固定球閥執(zhí)行標(biāo)準(zhǔn)
1、設(shè)計和制造:GB/T 12237; API 608
2、檢驗和試驗:GB/T13927; API 598
3、法蘭連接:JB/T 79.1-4; ASME B 16.5
4、結(jié)構(gòu)長度:GB/T 12221; ASME B 16.10
結(jié)構(gòu)特點及用途
1、操作省力:介質(zhì)壓力在球體上產(chǎn)生作用力全部傳遞給上下軸承,球體不會相對位置移動,兩端閥座密封受力均勻,操作力矩低。
2、采用彈簧預(yù)加載荷的可動金屬潤座結(jié)構(gòu),能適用高溫、高壓以及各種介質(zhì)管路。
3、根據(jù)客戶要求,可以設(shè)計能適用于含顆粒、料漿等介質(zhì)。
4、廣泛適用于食品、醫(yī)藥、石油、化工、天然氣、鋼鐵、環(huán)保、 造紙等介質(zhì)管路。
