    隔膜阀安装操作注意事项

    原文:

    安装:1必须遵守适用的安全规范。2管道在阀门安装前要确保无杂质,否则将会对阀门造成损伤。3连接阀门,注意对准管道。4所有阀门, 须在阀体上进行焊接工艺前,必须拆卸执行机构。5更换膜片时,需保持膜片与密封面的开位连接,再将膜片与密封面分离。对于气开功能 阀:1)对执行机构通气,使膜片提起,脱离密封面。2)交叉拆卸阀体上的四颗螺钉,使执行机构与阀座分离,切断气源,更换膜片。3)对执行 机构通气,使膜片收起。4)将膜片与阀座上的密封面对好,交叉安装固定螺钉,反复通气活动几次。5)关闭膜片阀试漏后,可正常使用。对 于气闭功能阀:1)切断执行机构气源,使膜片提起,脱离密封面。2)交叉拆卸阀体上的四颗螺钉,使执行机构与阀座分离,通气,更换膜片。 3)在使膜片收起状态下将膜片与阀座上的密封面对好,交叉安装固定螺钉。5)反复通气活动几次,关闭膜片阀试漏后,可正常使用。对于双 动功能阀:1)切断气源,使膜片提起,脱离密封面。2)交叉拆卸阀体上的四颗螺钉,使执行机构与阀座分离,切断下气缸气源,上气缸充气,更 换膜片。3)将下气缸充气,使膜片收起。4)将膜片与阀座上的密封面对好,交叉安装固定螺钉,反复通气活动几次。5)关闭膜片阀试漏后,可正常使用。

    Installation: 1 must comply with the safety rules of the applicable. 2 pipeline before installing the valve in to ensure that no impurities, otherwise it will cause damage to the valve. The 3 is connected to the valve, attention at the pipeline. 4 all valves, shall be carried out on the valve body welding process, must remove actuator. 5 replacement diaphragm, need to keep the film is connected with the sealing surface of the open position, then the diaphragm and sealing surface separation. For the open air valve: 1) to the actuator ventilation, so that the diaphragm up, out of the sealing surface. 2) the four screws on the cross removing the body, make the implementation of separation, mechanism and the valve seat to cut off the gas source, the replacement of the diaphragm. 3) to the actuator ventilation, so that the diaphragm. 4) the sealing diaphragm and the valve seat on the face, cross mounting screws, repeated several times the ventilation activities. 5) closed diaphragm valve leakage test, can use normally. For gas closed function: 1) cut off valve actuator air, so that the diaphragm up, out of the sealing surface. 2) the four screws on the cross body disassembled, the actuator and valve seat isolation, ventilation, the replacement of the diaphragm. 3) in the folded state of the sealing diaphragm diaphragm and the valve seat on the face, cross mounting screws. 5) repeated ventilation activities several times, closed diaphragm valve leakage test, can use normally. For double action hydraulic function: 1) cut off the gas source, so that the diaphragm up, out of the sealing surface. 2) the four screws on the cross body disassembled, the executing agency separation and valve seat, cut off the lower cylinder gas cylinder, pneumatic, change of diaphragm. 3) the cylinder filling, so that the diaphragm. 4) the sealing diaphragm and the valve seat on the face, cross mounting screws, repeated several times the ventilation activities. 5) closed diaphragm valve leakage test, can use normally.
