隔膜阀的基本知识、结构、及应用: 1、采用橡胶或塑料等软质密封制作的隔膜,密封性较好。由于隔膜为易损件,应 视介质特性而定期更换。
2、受隔膜材料限制,隔膜阀适用于低压和温度相对不高的场合。
3、隔膜阀按结构形式可分为:屋式、直流式、截止式、直通式、闸板式和直角式 六种;连接形式通常为法兰连接;按驱动方式可分为手动、电动和气动三种,其中 气动驱动又分为常开式、常闭式和往复式三种。
4.一般不宜用于温度高于60度及输送有机溶剂和强氧化介质的管路中,也不宜在较 高压力的管路中使用

Basic knowledge of the diaphragm valve, structure, and application : 1、Made of rubber or plastic soft seal diaphragm, sealing is good. Because the diaphragm for wearing parts, should be replaced periodically depending on the dielectric properties.
2、Restricted by the diaphragm material, diaphragm valve is suitable for the occasion of relatively low pressure and temperature is not high.
3、Diaphragm valve can be divided into: the form of the structure type, once-through, cut-off, cut-through, ram and right Angle type six kinds; Form is usually connected with flange connection; According to the drive mode can be divided into manual, electric and pneumatic three, including pneumatic drive is divided into often open, often closed and reciprocating three .
4.Should not be commonly used for temperature higher than 60 degrees and organic solvents and strong oxidizing medium pipeline, unfavorable also used in high pressure pipeline.
