天然气阀门维护安全操作手册一、天然气阀门的类型及功能在开始维护操作之前,我们先来了解一下常见的天然气阀门类型及其功能。
1、球阀球阀的阀芯是一个中间有通道的球体,通过旋转球体来控制天然气的通断。
球阀操作简单,密封性好,常用于主管道的开关控制。
2、截止阀截止阀的阀芯是一个锥形塞,通过上下移动来控制天然气的流量。
截止阀适用于需要精确调节流量的场合。
3、安全阀安全阀是一种自动保护装置,当管道内的压力超过设定值时,安全阀会自动开启,释放多余的压力,以保护管道和设备的安全。
二、维护前的准备工作1、工具准备准备好必要的工具,如扳手、螺丝刀、检漏仪、密封胶等。
确保工具完好无损,且符合天然气阀门维护的要求。
2、个人防护装备佩戴好个人防护装备,包括安全帽、防护手套、护目镜等,以防止在操作过程中受到伤害。
3、关闭阀门并放空在进行维护之前,务必先关闭上游和下游的阀门,将管道内的天然气放空,以避免天然气泄漏造成危险。
4、设立警示标识在维护现场周围设立明显的警示标识,禁止无关人员进入,防止发生意外。
三、维护操作步骤1、外观检查首先,对天然气阀门的外观进行检查,查看是否有腐蚀、变形、损坏等情况。
如果发现问题,应及时记录并采取相应的措施。
2、清洁使用干净的布擦拭阀门的外表面,去除灰尘和污垢。
对于难以清洁的部位,可以使用适量的清洁剂,但要注意清洁剂不能对阀门造成腐蚀。
3、密封检查检查阀门的密封性能,观察是否有泄漏现象。
可以使用检漏仪在阀门的连接处和密封部位进行检测,如果发现泄漏,应及时更换密封件。
4、操作灵活性检查手动操作阀门,检查其开启和关闭是否灵活,有无卡涩现象。
如果存在卡涩,应查找原因并进行处理,可能是阀芯有杂物或者润滑不足。
5、内部部件检查对于一些可拆卸的阀门,可以拆开检查内部部件的磨损情况,如阀芯、阀杆等。
如有磨损严重的部件,应及时更换。
6、润滑对阀门的活动部件进行润滑,以保证其操作的灵活性。
但要注意使用的润滑油应符合天然气阀门的要求,不能与天然气发生反应。
BULLETIN 400G-40JUNE 1993 安装和维护手册用于3"-12"水击泄压阀(氮气控制型)SECTION 1 安装和维护说明3"-12"水击泄压阀安装和启用1. 在安装水击阀以前,请确定阀门前的管道内没有脏东西、废弃物和金属屑,如果有条件,最好将阀门上游钢管进行吹扫,去除杂物。
2. 将阀门安装在管线上,确定阀门上游螺栓连接牢固。
(注意:为平抑温度变化产生的压力设定漂移,最好将扩大阀芯用的温差补偿氮气瓶埋地)。
3. 确定氮气供应系统的阀门是关闭的。
4. 连接氮气供应管线,从氮气供应系统阀门(H)到充气阀(D)。
5. 将阀门至于操作状态:5.1. 在开始使用水击泄放阀系统之前,应先打开连通温差平抑氮气瓶的截断阀(E),打开氮气充气阀(D)。
5.2. 缓慢打开氮气控制柜后的氮气瓶开关。
不要快速打开高压氮气瓶,避免高压氮气冲入系统损坏系统。
5.3. 缓慢调整氮气控制柜内的调压阀,顺时针为增加压力,直至调压阀下游(左侧)和水击阀上氮气压力表的压力达到标牌显示值,此时,水击阀和温差平抑氮气瓶都已经充压完成。
5.4. 缓慢打开水击阀后的截断闸阀(B)。
5.5. 缓慢打开水击阀前的截断闸阀(A)。
此时阀前压力应低于阀腔内压力,阀门保持关闭。
6. 水击阀停止使用:6.1. 缓慢关闭水击阀前的截断阀(A)。
6.2. 缓慢关闭水击阀后的截断阀(B)。
6.3. 通过水击阀前后管道上的排放阀将阀门前后管道内的压力泄出,如果没有排放阀的设计,则在拆除阀门时,应缓慢松开阀门与管道连接的螺栓,让压力从法兰连接处泄出。
关闭水击阀上的充气阀(D)和截断阀(E)。
缓慢打开水击阀上部的泄压阀(F),将阀腔内的压力泄出。
水击泄压阀的修理注:在阀门部件专有名称后,括号内的编号为阀门部件的编号,详见阀门的拆解图形的指示。
1. 确定阀门前后,及阀腔内压力已经泄出。
2. 如图二所示,将氮气控制系统取下;或将连接氮气控制系统的氮气管连接接头分开。
1、手动阀门的正确操作手动阀门是设备和装置上使用很普遍的一种阀门,它是通过手柄、手轮来操作的。
一般情况下手柄、手轮顺时针旋转规定为关闭方向,逆时针旋转规定为开启方向。
但有的阀门启闭方向与上述相反,故操作前应注意检查启闭标志后再操作手动阀门,其手柄、手轮的大小是按正常人力设计的。
因此,在阀门使用上规定:不允许操作者借助杠杆和长扳手启、闭阀门。
同时,手柄长度、手轮直径小于320mm的,只允许一个人操作;直径等于或超过320mm的手轮,允许两人共同操作,或者允许一人借助适当的杠杆(一般长度不超过0.5m)操作。
但隔膜阀、非金属阀门是严禁使用杠杆或长扳手操作的,也不允许用过大、过猛的力关闭阀门有的操作者习惯使用杠杆和长扳手操作手动阀门,认为关闭力越大越好,其实不然。
这样会造成阀门过早损坏,甚至酿成事故。
实践证明:除撞击式手轮外,过大过猛地操作阀门容易损坏手轮、手柄,擦伤阀杆和密封面,甚至压坏密封面。
其次,手轮、手柄损坏或丢失后,应及时配齐,不允许用活扳手代用。
闸阀和截止阀之类的阀门,关闭或开启到头(即下死点或上死点)时要回转1/4~1/2圈,使螺纹更好密合,以有利操作时检查,以免拧得过紧损坏阀门。
较大口径的蝶阀、闸阀和截止阀,有的设有旁通阀。
旁通阀的作用是平衡进出口压差,减少开启力矩。
开启时,应先打开旁通阀,然后再开启大阀门。
开启蒸汽阀门前必须先将管道预热,排出凝结水。
开启时要缓慢,以免产生水锤现象,损坏阀门和设备。
开闭球阀、蝶阀、旋塞阀时,当阀杆顶面的沟槽与通道平行时,表明阀门在全开启位置;当阀杆向左或向右旋转90。
时,沟槽与通道垂直时,表明阀门在全关闭位置。
有的球阀、蝶阀、旋塞阀以扳手与通道平行为开启,垂直为关闭。
三通、四通阀门的操作应按开启、关闭、换向的标记进行,操作完毕后应取下活动手柄。
对有标尺的闸阀和节流阀,应检查调整好全开或全闭的指示位置。
明杆闸阀、截止阀也应记住它们全开和全闭的位置,这样可以避免全开时顶撞死点。

This action results in the clockwise rotation of the drive shaft.∙ With air assist : Applying air pressure to the outside chamber(s) through Port 2 forces the piston(s)inward. This action results in the clockwise rotation of the drive shaft. As the piston(s) are driven inward, from the stored energy in the compressed spring(s) and air pressure, air is exhausted from the inside chamber through Port 1.4.3 Spring Return (SO)4.3.1 CW MovementApplying air pressure to Port 1 drives the piston(s) outward, which compresses the spring(s) and turns the drive shaft clockwise as the air volume on the outside of the piston(s) exhausts through Port 2. 4.3.2 CCW Movement∙ With no air assist: Exhausting air from the inside chamber through Port 1 allows the stored energy in the compressed spring(s) to force the piston(s) inward. This action results in the counterclockwise rotation of thedriveshaft.∙ With air assist: Applying air pressure to the outside chamber(s) through Port 2 forces the piston(s) inward. This action results in the counterclockwise rotation of the drive shaft. As the piston(s) are driven inward, from the stored energy in the compressedspring(s) and air pressure, air is exhausted from the inside chamber through Port 1.5 Installation 5.1 Installation on ValvesWARNING : FOR YOUR SAFETY, IT IS IMPORTANT THAT THE FOLLOWING PRECAUTIONS BE TAKEN BEFORE ANYDISASSEMBLY OF THE ACTUATOR OCCURS.▪ Depressurize the lines and cylinder of the actuatorbefore removing any components.▪ On spring return actuators, be careful to loosen theend cap bolts evenly due to the preload on the springs.Triac actuators are mounted directly to valves or adapted to the valve by means of an intermediate bracket and coupler. The coupler adapts the output of the actuator to the valve shaft. Pipelines can behorizontal, vertical, or other positions. When mounting the actuator to a valve using a mounting kit; the drive shaft, coupling device and valve stem should becentered and concentric to prevent any side loading to the bottom pinion radial bearing and valve stem seal area. After mounting, it may be necessary to adjust the end of travel stop for proper open or closed valve position. Pneumatically stroke the actuator several times to assure proper operation with no binding of the coupler.5.2 Air SupplyPneumatic piping to the actuator and associated accessories should follow the best practices for instrument pneumatic piping systems:∙ Line shall be free of water, oil, pipe sealant or other contaminants.∙ Operating medium is to be filtered dry air or inert gaswhich is filtered to 50‐micron particles size or less.∙ Actuator shall be supplied with proper air pressure and air volume. ∙ Triac 3R Scotch Yoke Actuators shall not exceed a maximum working pressure of 150 psi. ∙ Spring Return Models:Note: If exhaust port is not piped, it is important that the exhaust port is not exposed to a corrosive atmosphere.Please contact A ‐T Controls for possible solutions if non ‐typical conditions exist.5.3 LubricationTriac 3R Scotch Yoke Actuators are lubricated from the factory and no additional lubrication is required unless the actuator will be performing more than 100,000 cycles.∙ If more than 100,000 cycles will be performed, an oil mist lubricator is recommended.[1] [2]o Use oil type VG32 Class in temperature range from 15 to 158°Fo Set oil mist lubricator to lowest setting. [1]: If a Triac Scotch Yoke Actuator has been in operation with oil mist lubrication, it cannot be discontinued. [2]: If the actuator is equipped with a pneumatic positioner or controller, oil mist lubricated air shall not be used unless the instrument manufacturer indicates that used instrument is compatible with lubricated air.5.4 Travel AdjustmentWARNING : TO AVOID CATASTROPHIC FAILURE TO ACTUATOR,AIR MUST BE REMOVED FROM ACTUATOR BEFORE ANY TRAVEL ADJUSTMENTS ARE MADE.The Triac 3R Scotch Yoke Actuators have travel stopadjustments in both the clockwise andcounterclockwise directions. A 5° overtravel featureprovides adjustments from ‐5° to +5° at the 0° clockwiseposition, and from 85° to 95° at the 90° counterclockwise position.All actuated valves require accurate travel stop adjustments at both ends of the stroke to obtain optimum performance and valve seat life. Theaccumulation of tolerances in the adaption of actuators to valves is such that there must be a range ofadjustment for both ends of the stroke to achieve the expected performance. See the valve manufacturer’s IOM on how the travel should be adjusted. The following are typical features seen:∙ Ball & Plug Valves: require precise adjustment at the open and closed position. This is to protect the seat from the flow media and to assure absolute shut ‐off in the closed position.∙ Butterfly Valves: require precise adjustment at the open and closed position. This is to assure full shut ‐off, to prevent disc overtravel which can damage the seat in the closed position, and to assure maximum flow in the open position.∙ Tee Assemblies: where two valves are operated in tandem through a single operator, (3‐wayconfiguration) require precise adjustment at both ends of the stroke. This is to assure the seating of both valves.6 Disassembly ProceduresWARNING : FOR YOUR SAFETY, IT ISIMPORTANT THAT THE FOLLOWING PRECAUTIONS BE TAKEN BEFORE ANY DISASSEMBLY OF THE ACTUATOR OCCURS.▪ Depressurize the lines and cylinder of the actuatorbefore removing any components.▪ On spring return actuators, be careful to loosen the endcap bolts evenly due to the preload on the springs. ▪ Disconnect electrical supplies6.1 Removing End Caps6.1.1 DA & DR Models1.

Relieve all pressure from the valve and remove it from the system.2. Turn valve stem to full open position.3. Loosen the packing gland locking device.4. While holding the valve body secure, use a torque wrench to tighten the packing gland to the value shown on the attached Installation Summary Chart. If a torque wrenchis not available, tighten the packing gland approximately 1/16 turn.5. Pressurize the valve to the maximum operating pressure and check for leaks.6. If the packing still leaks, relieve all pressure in the valve and repeat steps 4 and 5. If the packing does not seal after several attempts, it needs replaced (refer to Section 3.0).7. Reinstall the packing gland locking device.Section 3.0Packing or Stem Replacement1. Relieve all pressure from the valve and remove it from the system.2. Turn valve stem to full open position.3. Remove the packing gland locking device.Model # Order # Serial # Mfg. DateDrawing #3Parker Autoclave Engineers Instrumentation Products Division Erie, PA USA | Cat. 02-0024ME4. While holding the valve body (or housing for HT and LT valves) secure, unthread and remove the packing gland. The packing will stay on stems that have a larger stem tip below the packing (see Fig. 3: SW8, 10/20SM9, 10/20SM12, 10/20SM16).Note: For HT and LT valves, the housing must be removed where the stem tip is larger than the body cone ring ID (SW6, SM12 and SM16 valves). Remove the housing locking device and unscrew the housing from the valve body.5. Autoclave Engineers manual valves have three different type of stems; one piece non-rotating (figure 2), two piece pinned non-rotating (figure 4) and rotating (figure 5). Follow steps 6-9 for one piece non-rotating stems, steps 10-11 for two piece pinned non-rotating stems andstep 12 for rotating stems.One piece non-rotating stem 6. For stems without a larger stem tip, remove the bottom washer, packing and packing washer in the body. Place the bottom washer, packing and packing washer in the body. If the stem does not require replacement, screw the packing gland back into the body and tighten the packing gland to the value in the Installation Sum- mary Chart.7. Remove the handle by loosening the set screw(s) located in the larger hole of t he handle (use a 5/32 hex wrench for the 3" long handle, a 3/16 hex wrench for the 4" and 10-1/4" long handle) and remove it from the stem sleeve. Unscrew the stem from the packing gland. Remove the two nuts and thrust washer from the top of the stem assembly. Remove the stem from the stem sleeve. Remove the bottom thrust washer from the stem. For SW8, 10SM9 and 20SM9 valves, remove the stem collar by unscrewing it clockwise. For stems with a larger stem tip, remove the packing washer and packingfrom the stem.8.Clean thrust washers and all surfaces which mate with thrust washers with a clean cloth. Apply non-hardening lubricant (Jet-Lube SS-301 or similar) lightly to both faces of the thrust washer and the sleeve threads.9. For stems with a larger stem tip, place the bottom washer, packing and packing washer on the stem (remove the bottom washer from from the old stem if the stem is being replaced). For SW8, 10SM9 and 20SM9 valves, place the stem collar on the stem by threading it counter-clockwise. Place first thrust washer on the stem and slide stem into stem sleeve. Place second thrust washer on the stem sleeve. Replace hex nut lightly against the upper thrust washer and thread the stem assembly fully into the packinggland. Screw the packing gland into the body and tightento the value in the Installation Summary Chart. Open the valve completely, then close it one turn to remove the play. Finger tighten the hex nut, then use a wrench to tighten it approximately 1/8 of a turn. Install the lock nut and finger tighten it in place. While holding the lock nut secure, loosen the hex nut from the top washer and tighten it against the lock nut approximately 1/16 of a turn. Replace the handle by lining the hex socket set screw up against the flat spot on the stem sleeve and tightenit in place (DO NOT OVERTIGHTEN). In order to have a nonrotating stem, a slight amount of free play must exist between the stem sleeve and shaft. The handle should have a 10 degree maximum free play for "backlash". If the free play is excessive, it will be necessary to remove the handle and loosen the lock nut and tighten the hex nut further against the thrust washer. Tighten the lock nut as indicated above and check for free play. When the desired "backlash" is achieved, replace the handle as described above. Re-install the locking device.Two piece pinned non-rotating stems10.

Remove the packing washer and packing from the stem. If a new lower stem is required, remove the housing andcone ring from the old stem and place the cone ring and housing over the new lower stem. Place the bottom washer, packing and packing washer on the stem. Insert the lower stem into the upper stem so that the groove pin holes line up. Drive the groove pin into the hole until it is flush with the outside diameter of the upper stem.11. Lubricate stem sleeve threads with Jet-Lube SS-301 or similar lubricant. Thread the stem sleeve all the way into the packing gland or the insert so that the stem is in the full open position. While holding the housing in a vice, torque the packing gland to the value in the Installation Summary Chart and tighten the locknut. Apply silicone grease or similar lubricant to the sealing surfaces of the cone rings. Apply Jet-Lube SS-301 or similar lubricant to the threads. Screw the housing into the valve body and torque the housing to the value in the Installation Summary Chart. Replace the housing locking device.Rotating Stem 12. Remove the handle from the stem.

一.线路截断阀和站场ESDV阀(驱动方式:气液联动连接形式:全焊接厂商:CAMERON卡麦隆)1.安装注意事项1.1阀门吊装拉运1.1.1 应采用正确的方式吊装阀门,使阀体支撑负荷。
----------------------------------------警告:其它凸出部件上。
支耳和阀门端颈为系吊链的正确位置,请切勿将吊链系于手轮、齿轮箱或执行器----------------------------------------------1.1.2如果阀门上装配有吊耳, 则应用吊耳吊装阀门。
1.1.3在吊装阀门期间应使阀门端部保护盖保持在原位。
只有当阀门安装完毕后,才可移去保护盖。
1.1.4 吊装时应逐个阀门吊装,不得多个阀门同时吊装。
阀门在摆放时禁止叠加。
----------------------------------------------警告:在吊装时,请注意保护阀门端面及阀门配件不受损坏,否则将导致阀门受损。
----------------------------------------------1.1.5 阀门拉运前要对阀门进行逐个检查,对存在外观缺陷、手轮变形、部件损坏的情况,施工单位可以拒绝拉运。
1.1.6阀门拉运时要对每台阀逐个固定,防止阀门在运输过程中倾倒、相互摩擦和碰撞。
1.1.7 阀门在拉运时要采取防雨措施。
----------------------------------------------1.1.8 阀门运抵现场后要设专人负责保管。
存放的场地要求平整,下铺上盖,排列整齐,小阀门可以放在货架上。
存放时注意保护好阀门封盖和法兰密封面。
禁止在存放期间闲杂人员对阀门进行开关。
----------------------------------------------阀门位置:卡麦隆球阀可安装在任何位置,阀门的任何一端均可作为上游端。
图1-正确的利用端颈吊装方式图 2 –正确的利用吊耳的吊装方式1.2焊接说明:阀门焊接连管前,前后管道应同轴,断面应平行。
带有支架的阀门必须放置在加固的基础之上,使得球阀不承受来自管线的附加应力。
阀门安装前管线必须吹扫干净,清除掉管道内的油污、焊渣和杂物。
1.2.1在预热、焊接或热应力释放时,距焊缝3″(75mm)以外阀体上的任何点处温度均不能超过400°F(200°C)。
请用测温色笔检验温度。
1.2.2在把卡麦隆球阀最终焊接在管线之前,应用1″宽的保护带盖上阀门密封自三点钟至九点钟区域(球阀与阀座之间的密封和阀座与端部之间的密封)。
这样有助于防止任何杂质落入这个区域。
在开工或试压之前,管线系统应通球清楚杂质。
1.3安装执行器1.3.1确认阀门已处于全开或全关位置,执行器处于合适的位置。
1.3.2首先确定希望的执行器方位,然后进行安装。
执行器可以有不同的安装位置(推荐阀表面使用一薄层润滑剂)。
1.3.3执行器安装完毕后,应使用螺栓进行固定。
如果螺栓孔没有对齐,找正过程中可以轻轻打开或关闭执行器,直至对正。
如果不能操作执行器,应完成设定限位器的步骤。
1.3.4阀位观察孔对3″及以上阀杆尺寸的的阀门,当把管塞和呼吸塞从适配法兰上移去,即可观察到与阀门限位有关的键轴限位的位置。
当在开位观察孔中观察到键轴限位与阀位限位相重叠时,阀门处于全开位。
当在关位观察孔中观察到键轴限位与阀位限位相重叠时,阀门处于全关位。
下图(左)表示了3″及以上尺寸阀杆的阀门观察孔的位置,下图(右)表示了4″及以上尺寸阀杆的阀门观察孔的位置。
(图中表示均为开位)1.4加长杆部分结构图由于线路截断阀室全部采用了阀池安装方式,因此球阀的阀体部分处于地下,地面见不到阀体。
阀体的各个接口用接管引至地面。
加长杆部分如下图所示:1.5延伸到地面的各个接口管排列如下:1.6阀体、执行机构整体连接图2. 水压测试安装卡麦隆阀门的管线系统进行静压测试时,请遵循以下步骤以避免造成阀门内密封面和阀座密封的损坏。
2.1 当向管线系统加入试验介质时,阀门应处于全开位,这样可以把管线中的碎屑通过阀球通径冲刷出管线。
2.2 一旦管线吹扫完毕并向系统中充满试验介质,球阀应处于中间位置(约离全开位10°的位置)。
这样试验介质即可流入阀腔。
这时阀门已做好试压的准备。
2.3 完成静水压试验后,在将试验介质从管线系统中排除之前,应把阀门返回全开位。
阀腔中试验介质可通过阀体侧底部的排污口排出阀外。
2.4 一旦阀门及管线系统完成通球清管并注入产品,阀门应移至半开位(约离全开位10°的位置)。
阀腔中遗留的试验介质应通过阀体下部的排放口放空。
如果阀门有阀杆加长管,排放口应设置在延长管的顶部之上装配法兰之下。
2.5 打开阀体排放口将使得截留在阀腔中的试验介质流出来。
将排放口保持在开位直至所有试验介质通过排放口排净。
2.6 关闭排放口并将阀门转向全开位或需要操作的位置。
2.7 阀座腔应注入工厂批准的阀门清洗液以消除任何滞留的试验介质。
3.二级阀座密封(润滑剂和密封脂的注入)对安装在线的阀门,清洗和注入密封脂的操作是唯一可在线带压进行的补救方法。
作为标准配置,所有尺寸的球阀上均有密封脂注入口,其注入口由两级止回阀组成以保证其注入密封脂的可靠性。
在阀门维护方面,配合Cameron旋转阀座,可加注清洗剂和润滑剂并使之均匀分布以实现对球阀密封面的清洗和保养。
阀座注脂密封示意图阀杆采用三重密封,配有盘根注入装置,Δ型聚四氟材料为主密封(上下位置),上下密封环中间有不锈钢弹簧片预紧的聚四氟密封唇,无需润滑,紧急情况时可注入密封脂。
4.阀位指示顶部阀杆有整体式限位器(1/4圆周的挡块),保证阀门精确的开关位置,避免损伤阀门密封。
同时在阀颈部开有观察孔,可以通过肉眼观察阀门开关位置。
5.气液联动执行机构操作方法操作是阀门日常维护的重要部分。
阀门操作有利于消除聚集在阀座表面或阀球表面的杂质,阀门每次操作均可使阀座环旋转15º,并均匀分布对阀座内嵌体的磨损。
5.1一般规定5.1.1操作阀门前应注意检查阀门的开闭标志后再操作。
5.1.2对于长时间(6个月以上)没有动作和进行清洗、润滑操作的球阀,在操作球阀前应先注入少量清洗液密封脂,以保护阀门密封。
5.1.3检查阀门状态,如阀门为全关位,则检查阀门两端压力,带有旁通回路的球阀当两端压差大于1MPa时,打开球阀进出口两端的压力平衡阀,平衡球阀两端压力。
阀门上下游压差小于1MPa,开始操作阀门。
5.1.4球阀操作完成后必须仔细确认球阀的状态,必要时同调控中心共同确认。
5.1.5球阀只允许在全开或全关状态下运行,禁止用于节流或在非全开关位运行。
5.2气动操作(人工气压方式)5.2.1如果要开启装置:拉住左手柄进行开启装置的切换,直至装置顶部指示器指到全开位置,此时可听到气流声明显减小。
5.2.2如果要关闭装置:拉住右手柄可进行关闭装置的切换,直至装置顶部指示器指到全关位置,此时可听到气流声明显减小。
操作人员完成操作后,必须确认阀门的开关位置是否满足要求,带远传的装置需确认其转传信号正确,确认无误后方可离开现场。
5.3手动操作(人工液压方式)5.3.1如果要关阀:按下手动泵上右端按钮,提起手动泵手柄至最高端,向下按动手柄;重复上步,直至阀位指示器指到全关位置;阀门到达全关位后,按住手动泵中央的平衡阀按钮,按下手柄,将手柄复位。
5.3.2如果要开阀:按下手动泵上左端按钮,提起手动泵手柄至最高端,向下按动手柄;重复上步,直至阀位指示器指到全关位置;阀门到达全开位后,按住手动泵中央的平衡阀按钮,按下手柄,将手柄复位。
操作人员完成操作后,必须确认阀门的开关位置是否满足要求,带远传的装置需确认其转传信号正确,确认无误后方可离开现场。
5.4阀门限位器调节方法5.4.1拆除控制块下方的排气丝堵。
5.4.2用手动泵驱动装置,检查装置手动回路部分是否满足要求,并初调手动泵上的速度调节旋钮。
5.4.3连接氮气动力气源,将进入装置的气体压力调节到装置最低工作压力的1.5 倍,打开进气管路阀门。
5.4.4气动驱动装置关10~15度。
5.4.5调节装置限位调节器至最大位置,手动驱动装置开启到全开位,调节装置限位调节器使限位块与旋转叶片接触。
5.4.6气动驱动装置关10~15度,然后气动驱动装置至全开,观察阀门是否在全开位置。
5.4.7气动驱动装置关40~50度,根据阀门厂家提供的数据,在在球体中部沿水平方向做全关位的标记,手动驱动装置关至标记处。
