SAMSON 3780说明书调节阀维护及操作规程DCS系统对调节阀的控制主要通过调节阀自身的电气阀门定位器完成。
我司生产线上的调节阀为德国SAMS ON调节阀,SAMSON调节阀采用智能数字阀门定位器(3780,HART协议数字通信),其控制精度高,运行稳定。
定位器的主要性能介绍如下:结构与工作原理HART电气定位器是为连接气动调节阀而设计的,它可确保阀杆位置(受控变量)与控制信号(参考变量)之间的对应关系。
它将控制装置 4至20mA的输出信号和调节调的行程相比较,并产生一个相应的压力信号作为输出变量。
为此,用户需要提供辅助气源压力1.4-6巴。
定位器辅助能源是由4到20mA参考变量信号提供。
定位器由一个感应,非接触或位移传感系统,一个由2/2-通开关阀组成的电控阀块以及一个电控单元组成。
电控单元包含两个用于处理控制算法及管理通讯的微控器.一旦实际阀门行程值(实际值)与参考变量(设定点)之间出现偏差,微控器就会产生一个二进制脉冲调制信号去控制两个 2/2通开关阀,且分别由一个指定的放大器来控制。
其中一个阀控制排气,另一个控制气源.气源阀(3)将供气(7气源压力1·46巴)送到执行器(填充)。
排气阀(将执行器排出空气流排放到大气中(排气)。
这些开关阀即可以有开关状态—一常开。
常闭—一也可产生可变宽度的单脉冲。
对于这两个受控_阀门,阀林将会移动到与参考变连量相对应的位置。
如果没有系统偏差气源阀和排气阀都将关闭。
作为一个标准功能,定位器配有一个故障信息输出(根据DDN19Z34,NANUR标准的进制输出),用于向控制室发送故障信号。
成的激活位于定位器铰接盖上的写保护开关‘可防止设定被HART通讯修改。
作为对标准定位器型号的补充,有几个附加的选项用于扩展定位器功能。
带眼位开关的定位器为了在故障一安全电路中指示出阀门的最终位置,两个软件限位开关或两个接近开关被带强制排空功能的定位器一个控制定位器的6-24V电压信号,使得信压力施加到执行器。
系列型电气阀门定位器带通信应用型单作用或双作用阀门定位器用于装配到气动控制阀,自校准、自动适配控制阀和气动执行机构。
输入控制信号至行程至开启角度至数字式电气阀门定位器作为气动控制阀的重要附属装置,接受控制系统或控制器输出的电动控制信号,按预先设置关系辅助气动执行机构调整阀位并实现准确定位。
阀门定位器将从控制系统接收的输入控制信号(给定参数)和控制阀位行程或旋转角(被调参数)反馈量进行比较、处理,进而输出相应的气动控制信号(输出参数)给气动执行机构。

SamSon自力式调节阀值及国际领先水平产品。
我国阀门行业目前已经能生产十几大类产品。
如闸阀、截止阀、球阀、蝶阀、安全阀、止回阀、节流阀、旋塞阀、减压阀、隔膜阀、疏水阀、紧急切断阀等,最高使用温度570℃,最低-196℃、最高压力600MPa,最大通径5350MM。
尽管这些产品有力支援了国内经济建设,但是应该清醒看到我们的产品大都属于一般技术含量或劳动密集型产品,很少具有国际领先水平。
最近西气东输主管线招标,我们阀门企业全部落败就是一个令人遗憾的事实。
痛定思痛。
民族工业要振兴阀门行业要发展就一定要实施技术创新,调整产品结构,要勇于研制开发技术含量高、劳动附加值高具有国际领先水平的阀门产品如控制阀门和自动阀门类的调节阀,三通合流阔、三通分流阀,安全阀;球阀类的金属硬密封全焊接,高参数大口径阀;以及电站超临界C12-A合金钢阀门。
实施技术创新研究开发新产品有几条路,一是通过和院校科研机构合作,如最近开封高压阀门厂和中科院下属的“三维”公司合作开发的电站锅炉主蒸气调节阀就是具有国际领先水平的产品,其“压力降”大大低于国际标准,在电站行业具有非常前景;二是国外合作或技术引型自力式压力调节阀一、产品[自力式差(微)压力调节阀]的详细资料:产品型号:ZZC、ZZV型产品名称:自力式差(微)压力调节阀产品特点:ZZC和ZZV50mm.WC至0.1MPa自力式差(微)压调节阀是一种不需要外加能源的执行器产品。
可用于公称压力PN0.1、PN10。
差(微)压均可分段调节。
从50mm.WC至0.1MPa。
其用途十分广泛,可用于工业燃烧炉系统,控制两种物料,如煤气、空气流量配比,以达理想燃烧。
用于氢冷发电机组密封油系统,控制密封油与氢气间压力差,以确保可靠密封。
当差压阀的低压端通大气即为微压阀(差压阀负压,端压,力为零)。

(Note 1)For low temperature, use dry air with no condensation.(Note 2)Impact resistance:No malfunction when tested with a drop tester in the axial direction and at a right angle to the main valve and armature, one time each in bothenergized and de-energized states. (initial value)Vibration resistance:No malfunction when tested with one sweep of 8.3to 2000Hz in the axial direction and at a right angle to the main valve and armature, one time each in both energized and de-energized states. 3INSTALLATION Using a Pre-wired Connector4 wire round type connector (M 12) conforming to NECA (Nippon Electric Control Equipment Industries Association) standard 4202.Internal Wiring SpecificationTerminal numbers in the circuits are for a DIN connector . Numbers inside ( ) are pre-wired connector pin numbers.MAINTENANCE Installation and Maintenance ManualVQ7-6/7-8, ISO Standard Solenoid ValveDIN connectorwiring Specification Pre-wired connector wiring SpecificationPerform maintenance procedures as shown in the instruction manual.If handled improperly, malfunction or damage of machinery or equipment may occur.Equipment removal and supply/exhaust of compressed airWhen equipment is removed, first confirm that measures are in place to prevent dropping of work pieces and run-away of equipment, etc. Then cut the supply pressure and power, and exhaust all compressed air from the system using its residual pressure release function.When the equipment is to be started again after remounting or replacement, first confirm that measures are in place to prevent lurching of actuators, etc., and then confirm that the equipment is operating normally.Low frequency operationValves should be switched at least once every 30 days to prevent malfunction.(Use caution regarding the air supply.)Manual override operationWhen the manual override is operated, connected equipment will be actuated.Confirm safety before operating.Installation and Removal of Pilot Valve CoverRemovalTo remove the pilot valve cover, spread the cover's hook outward about 1mm witha flat head screw driver, and pull the cover straight off. If it is pulled off at an angle,the pilot valve may be damaged or the protective O-ring may be scratched.InstallationPut the cover back on straight without touching the pilot valve, and push it all the way until the cover's hook locks, without twisting the protective O-ring. (When pushed in, the hook opens and locks automatically.)Replacement of Pilot ValveRemoval1) Take off the sockets which are installed on the pilot valve pins by pulling themstraight upward.2) Remove the pilot valve mounting screws with a small screw driver.Installation1) After confirming installation of the gasket, securely tighten the mounting screwswith the proper torque shown in the table below.2) Put the sockets on straight and install them securely so that the receptaclehousings touch the coil surface as shown in the drawing below.If they are pushed in with excessive force, there is a danger of the sockets coming off of the receptacle housings. Confirm that the sockets do not protrude from the windows on the side of the receptacle housings.specific product catalogue.Momentary energizationIf a double solenoid valve will be operated with momentary energization, it shouldbe energized for at least 0.1 second.Leakage voltageParticularly when using a C-R element (surge voltage suppressor) for protection ofthe switching element, take note that leakage voltage will increase due to leakagecurrent flowing through the C-R element, etc.Low temperature operationAvoid ambient temperatures outside the range of -10 to 60°C (-5°C minimum forrubber seals). At low temperatures, appropriate measures should be taken to avoidsolidification or freezing of drainage and moisture, etc.Operation for air blowingWhen using solenoid valves for air blowing, an external pilot type or direct solenoidoperated type should be used. Also, supply to the external pilot port compressedair within the pressure range prescribed in the specifications.Mounting orientationIn the case of a single solenoid, the mounting orientation is unrestricted. In thecase of double solenoid or 3 position valves, mount so that the spool valve ishorizontal. Also, when mounting in a location with vibration or impact, mount sothat the spool valve is at a right angle to the direction of vibration.Do not use in locations where vibration or impact exceeds the product'sspecifications.7EUROPEAN CONTACT LIST7.1 SMC CorporationCountry Telephone Country TelephoneAustria(43) 2262-62 280Italy(39) 02-92711Belgium(32) 3-355 1464 Netherlands(31) 20-531 8888Czech Republic(420) 5-414 24611 Norway(47) 67 12 90 20Denmark(45) 70 25 29 00 Poland(48) 22-548 50 85Finland(358) 9-859 580 Portugal(351) 22 610 89 22France(33) 1-64 76 1000 Spain(34) 945-18 4100Germany(49) 6103 4020 Sweden(46) 8 603 12 00Greece(30) 1- 342 6076 Switzerland(41) 52-396 3131Hungary(36) 23 511 390 Turkey(90) 212 221 1512Ireland(353) 1-403 9000 United Kingdom(44) 1908-56 38887.2 WebsitesSMC Corporation SMC Europe Proper tightening torque Nm0.8 to 1.2。
