隔膜阀最突出的特点

隔膜阀最突出的特点

原文: 最突出特点是隔膜阀下部阀体内腔与上部阀体内腔隔开,使位于隔膜上方的阀杆、阀瓣个零件不受介质腐蚀,省去了填料密封结构,且不会产生介质外漏。1. 采用橡胶或塑料等软质密封制作的隔膜,密封性好。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,隔膜阀适用于温度和压力相对不高的场合。3. 按结构形式可分为:屋式隔膜阀、直流式隔膜阀、截止式隔膜阀、直通式隔膜阀、闸板式隔膜阀和直角式六种。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,其中气动驱动有分为常开式、常闭市和往复式三种。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。隔膜阀最突出的特点。

译文: The most prominent feature is the lower part of the diaphragm valve body cavity and the upper valve body cavity is separated, the in the stem and disc parts above the diaphragm is not subject to corrosion medium, eliminating the packing seal structure, and won’t produce leakage of medium. 1. Made of rubber or plastic soft seal diaphragm and good sealing. 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 temperature and pressure is relatively high. 3. According to the structural form can be divided into: the house type diaphragm valve, once-through diaphragm valve, cut-off valve, straight through the diaphragm valve, diaphragm gate type diaphragm valve and six right Angle type. 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 closed and reciprocating three often open, often. 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.隔膜阀最突出的特点。
