不鏽鋼截止閥

 
不鏽鋼截止閥J41W不鏽鋼截止閥說明:不鏽鋼截止閥系列(liè)産品,主要用來切斷(或接通)管路介質。适用于化工等行業的硝酸、醋酸等場(chǎng)合。該系(xì)列産品按國家(jiā)标準生産,具有結構(gòu)先(xiān)進,工藝性能,各項性能指标(biāo)達到先進标準水平。

不鏽鋼截止閥結構(gòu)特點
該型閥門采(cǎi)用平面密封和錐面(miàn)密封兩種密封型式,可使用于不(bú)同工況的介質要(yào)求,具有密封性能穩定,使(shǐ)用壽命長。逆時針轉(zhuǎn)動手輪驅(qū)使閥(fá)杆帶動閥(fá)瓣及膈膜迅速上升,打開通道(dào)使介(jiè)質順利通過。

設計與制造标準:
1、設計制造按GB12235-89
2、結(jié)構長度按GB12221-89
3、法蘭尺寸按JB/G79-94
4、閥(fá)門檢查和試驗按GB13927
