②操作时,人体不能正对阀杆顶部,以防阀杆受压喷出伤人。
③开关操作要平稳、用力咬均匀,严禁使用冲击力,一般情况用手操作即可,避免使用加工杠杆操作新阀。
④手轮(手柄)强度的设计是以操作所需的扭力值为参考依据的,因此不可将手轮(手柄)当做操作踏板及任意增长或套接加长杠杆,或以扳手来过度增加扭力,不能使用绳索等作用在手轮(手柄)上,再以起重机或滑轮来操作或吊运阀门。
⑤带手轮或手柄的隔膜阀,顺时针转动手轮为关,逆时针转动为开。
当阀门全开后,应将手轮反方向回转1-2圈。
带有其他执行机构的丝扣闸阀的操作方式应严格遵循产品说明书。
⑥高压差下,闸板半开半关状态下易损坏闸板,因此丝扣闸阀不能用于节流或调节,须一次性开启或关闭。

②隔膜阀操作时,人体不能正对阀杆顶部,以防阀杆受压喷出伤人。
③隔膜阀开关操作要平稳、用力咬均匀,严禁使用冲击力,一般情况用手操作即可,避免使用加工杠杆操作新阀。
④隔膜阀手轮(手柄)强度的设计是以操作所需的扭力值为参考依据的,因此不可将手轮(手柄)当做操作踏板及任意增长或套接加长杠杆,或以扳手来过度增加扭力,不能使用绳索等作用在手轮(手柄)上,再以起重机或滑轮来操作或吊运阀门。
⑤带手轮或手柄的隔膜阀,顺时针转动手轮为关,逆时针转动为开。
当阀门全开后,应将手轮反方向回转1-2圈。
带有其他执行机构的闸阀的操作方式应严格遵循产品说明书。
⑥高压差下,闸板半开半关状态下易损坏闸板,因此闸阀不能用于节流或调节,一次性完全开启或完全关闭。
隔膜阀阀可以安装在任意角度的管道上,但不宜倒装,通常可侧立式或卧式安装,以防止管道中杂质在密封面上滞留。
隔膜阀阀蝶板的开度与流量基本呈线性比例变化,如果用作控制节流,当节流幅度较大时,蝶板的背面易发生气蚀,有损坏阀门的可能,故蝶板开度不宜太小,一般要求其开度应大于15°。
当蝶板处于中间开度时,水流动力矩会起作用,故操作机构需加自锁功能。
隔膜阀阀安装时应使阀门处于关闭状态,以防阀体变形。
特别要防止焊接管道或法兰时焊渣掉在密封面上,以确保阀门严密性。
系统作水压试验时,中线沟槽蝶阀应处于开启状态。
隔膜阀阀在存放和保管期间应使蝶板开启4°~5°,以防止密封圈产生疲劳变形。
隔膜阀阀的蝶板进口侧装有弯头时,会形成偏流,蝶板开闭力矩会增大,故要求蝶板与弯头间应有不小于4倍管径的距离。
隔膜阀的密封原理是靠楔形闸板上的两密封面和阀体上的两密封面楔入时的紧密结合来达密封的。
使用楔形闸板的目的是为了提高辅助的密封载荷,以使金属硬密封沟槽闸阀既能对高介质压力,也能对低介质压力进行密封。

Flange covers serve as transport protection and must not be removed.3.3StorageIf the valve is not to be installed immediately on delivery, it must be properly stored.It should be stored in a dry room at as constant a temperature as possible.Storage over a prolonged period may necessitate moisture-proof packaging. A decision on this must be taken on the basis of the local conditions.3.4 Return consignmentsThe customer must ensure that the valves havebeen well flushed and cleaned before beingpassed on to the maintenance staff. This is ofparticular importance when the goods are returnedto the manufacturer.3.4.1GRAS certificateA GRAS certificate according to EUROPUMP on the field of application is to be enclosed with the returned goods.If necessary, safety precautions and decontamination measures are to be mentioned.Pre-printed forms can be requested from ITT Richter.4Product descriptionThe entire diaphragm valve is of a simple design. In comparison to conventional full-bore valves, it has the advantage that, apart from the diaphragm, the one-piece body is the only "wetted" part.The valves are protected against aggressive atmospheres on the outside with an epoxy paint.Richter diaphragm valves consist of the assemblies:- Body- Upperpart4.1BodyThe metallic body bears the following cast data as per DIN EN 19:− nominal diameter− nominal pressure− body material− manufacturer's code−melt number / foundry number− lining material4.2Upper partThe upper part of the diaphragm valve consists of the bonnet, compressor, diaphragm, stem/valve stem, threaded bushing, (stroke index), travel stop (DN 15 - 80), position indicator (DN 100– 200) and handwheel.4.3NameplateA nameplate on the body contains the following details :- RichterproductionNo.- Any customer-specific dataExample of production No.: 99 4875/2/1Please indicate the production number on all correspondence.5 InstallationTo protect the sealing surfaces againstcontamination and damage, the yellowprotective caps must remain on the flanges until just before installation.The plant must be flushed and free of loose solid matter.The installation space must correspond to the face to face dimen-sion.We recommend gaskets to protect the sensitive plastic sealing surfaces against damage by the mating flange.Gaskets with a PTFE jacket and a stainless steel inlay must be used if a flange is endangered by hard pipe flanges, e.g. made of metal or ceramic.The size of the gaskets must correspond to the nominal diameter of the valve.5.1Direction of flowThe direction of flow is not prescribed for diaphragm valves. The direction can be determined as required.5.2EarthingIf the valve has to be earthed, this can also be performed using the pipe screws.A tooth lock washer is placed under one nut of each valve flange. This penetrates the paint film and thus creates the electric contact with the screw.5.3 Tightening torques of the screw fittingsTighten the connection screws between thebonnet and body with a torque wrench.For recommended torques for the screws, see Section 9.6.CAUTION !CAUTION !6Operation6.1Initial commissioningNormally the valves are tested for leaks with water and air. Unless other agreements have been made, there may still be residual amounts of water in the bore of the valve. Beware of a possible reaction with the operating medium.After initial loading of the valve with operating pressure and tem-perature, the torques of all connection screws must be checked.6.2ShutdownIf the valve is to be dismantled, the local regula-tions are to be observed.Always make sure that the pipe and the vessel have been depressurised and emptied.Suitable protective action is to be taken to avert any risk to people and the environment throughany aggressive or toxic media leaking.If the dismantled valve is to be returned to the company's own workshop or to the manufacturer, it must be thoroughly cleaned.See also Section 3.4.After dismantling, immediately protect the plastic flanges of the valve against mechanical damage using flange caps.6.3Re-startingWhen re-starting the valve, make sure that, depending on the progress of shutdown, all the appropriate steps as described in Section 5 and Section 6.1 are repeated.6.4Inadmissible modes of operation and their consequencesWhen operating in the range of below-zero temperatures, the national regulations are to be observed.7 Maintenance• Check all connection screws of the valve in accordance withSection 5.3.• Check the working order of all other equipment in accordancewith the plant standards in the operating area:− body screws− safety stuffing box − air connections − control equipment − protective devices − etc.The exact arrangement and designation of all single parts belong-ing to the valve including the item numbers mentioned in the following instructions are contained in the arrangement drawing in Section 9.9.All maintenance work is to be performed with appropriate tools by qualified staff. The working practice applicable in the general mechanical engineering sector is to be observed.7.1Screw connectionsPeriodical checks of the tightening torques in line with the opera-tional requirements at the following points:•Connection screws between body and bonnet.•Pipe screws .For tightening toques, see Section 9.6.7.2CleaningThe valve is to be cleaned thoroughly before the start of repair work. Even if the valve has been properly drained and flushed, there could still be residual amounts of medium in the valve, e.g.between the sealing surfaces.Moreover, the plastic components may have absorbed medium which emerges gradually from the material after cleaning.Protective clothing should therefore be worn.See also Section 3.4.7.3Dismantling7.3.1MV (with handwheel)− Undo cover screws and remove upper part.− Turn stem into the threaded bushing until the compressor withthe diaphragm is exposed.− Turn diaphragm through 90° and lift off (bayonet catch).Observe safety regulations when working with the medium.When cleaning, do not treat mechanically but only use soft and/or liquid cleaning materials.7.3.2MVP (with actuator)-Open coupling and remove actuator.- Press stem into the bushing until the compressor with thediaphragm is exposed.-Turn diaphragm through 90° and lift off (bayonet catch).7.4Assembly-Insert new diaphragm, turn through 90° (bayonet catch).

隔膜阀a-es71t1230dn125说明书
手动隔膜阀的操作很近似于胶管阀的操作。
旋转手轮是压缩器下降,开始像阀体底壁推动隔膜。
在节流状态,手动操纵器旋转到所需的流量处之后并停留在该处。
在开-关状态,达到大压力时,两个表面则达到严密的密封。
当隔膜阀打开时,手动操纵器的旋转作用则相反,
当闭合元件提升后扩大了流动面积。
终,在全开位置,压缩器完全收缩到阀盖帽内部,隔膜远离物流。
在此点阀门达到它的全面积容量。
总之隔膜阀提供固有等百分比流动特性,该特性在操作时往往会直线运动。
1、隔膜阀开关不能用F扳手,而且开到底时,再关一圈,不能开到底。
2、丝杠要定期加黄油。
3、阀门关闭时不能用太大的力,以防膜片损坏。
4、螺栓要定期加黄油,以防生锈。
5、阀门损坏后,要拆开检查,如果只是膜片损坏,只更换膜片就可以了。
更换膜片时,阀门要处于全开状态。
安装与维护
隔膜阀安装前应仔细核对管路的运行条件是否与本阀规定的使
用范围相符,并应清洗内腔,以防止污物卡阻或损伤密封部件。
橡胶衬里层和橡胶隔膜表面切勿涂刷油脂类物品,以防橡胶溶胀,影响隔膜阀使用寿命。
手轮或传动机构,不允许作起吊用,并严禁碰撞。
手动操作隔膜阀时,不得借助于辅助杠杆,以防扭力过大而损伤驱动部件或密封部位。
隔膜阀应存放在干燥通风的室内,严禁堆放,库存隔膜阀的两端通道必须封口,且启闭件应处于微开启状态。
