双偏置蝶阀和三偏置蝶阀
2019年7月29日
蝶阀是最常用的阀门之一,我们常用的有同心软密封蝶阀、双偏心蝶阀和三偏心蝶阀。通常同心软密封蝶阀主要应用于常温、低压工况下,如给排水、水利工程、市政建设等领域。那么什么是双偏心蝶阀呢?什么是三偏心蝶阀?它们适用于什么条件?双偏心蝶阀PTFE阀座双偏心蝶阀耐腐蚀。金属阀座双偏心蝶阀耐高温。但金属阀座双偏心蝶阀不能承受高压。由于板与密封面直接接触,在高压工况下使用会造成泄漏。双偏心蝶阀应用于给排水、污水、建筑、石油、化工、轻纺、造纸、水电、冶金、能源等领域。三偏心蝶阀三偏心蝶阀是将同心圆蝶阀和双偏心蝶阀结合起来的一种阀门。There are more choices for the seat material of triple eccentric butterfly valves, and is able to suit both low and high temperature and All kinds of acid, alkali and other corrosive media. In addition, triple eccentric butterfly valve can achieve zero leakage, especially suitable for large diameter valve, and, in the use of shut-off valve, can replace the gate valve and ball valve. When used to regulate the flow rate, it can replace the cumbersome globe valve. At present, the triple eccentric butterfly valve is widely used in oil mining, oil refining, petrochemical, energy generation and other important industrial fields of the pipelines. With people's continuous research,it is believed that the triple eccentric butterfly valve will be used in more and more fields.
