不銹鋼球閥應(yīng)用規(guī)范:
1、設(shè)計制造按GB12235-59
2、結(jié)構(gòu)長度按GB12221-89
3、法蘭尺寸按JB/T79-94
4、閥門檢查和試驗按GB13927
一,不銹鋼球閥產(chǎn)品結(jié)構(gòu)特點;
1. 閥門采用固定球閥,新穎浮動閥座結(jié)構(gòu) 形式,密封可靠;
2. 特種材質(zhì)密封,耐高溫,耐磨損,壽命長;
3. 上閥軸沒有防脫機(jī)構(gòu),可以在有介質(zhì)壓力的情況下調(diào)整填料;
4. 閥座的優(yōu)良結(jié)構(gòu),在閥座支撐面內(nèi)側(cè)精確加工一道特制耐磨封圈,當(dāng)封圈嚴(yán)重時磨損時,密封福與
球體間形成暫時的金屬對金屬密封圈,閥門填料墊片均采用耐高溫石墨填料。保證閥門在高溫發(fā)生時無
泄漏;
