不銹鋼美標(biāo)法蘭球閥設(shè)計制造標(biāo)準(zhǔn)是API 600、API 602,在管路中主要用來做切斷、分配和改變介質(zhì)的流動方向。產(chǎn)品整體硅溶膠精密鑄造閥體,閥體表面精細(xì)、美觀,無需打磨。設(shè)計有防靜電,耐火結(jié)構(gòu),閥體等部件選用優(yōu)質(zhì)不銹鋼并經(jīng)酸洗、鈍化,檢查和試驗用不含任何油脂的純凈自來水進(jìn)行高壓密封試驗,經(jīng)上述特殊工藝處理,此類球閥不僅操作快速靈便,流阻小,安全可靠,而且使用壽命長(密封副沖刷?。?。
工作原理:
不銹鋼美標(biāo)法蘭球閥的工作原理是靠旋轉(zhuǎn)閥戀來使閥門暢通或閉塞。球閥開關(guān)輕便,體積小,可以做成很大口徑,密封可靠,結(jié)構(gòu)簡單,維修方便,密封面與球面常在閉合狀態(tài),不易被介質(zhì)沖蝕,在各行業(yè)得到廣泛的應(yīng)用。
