不銹鋼美標(biāo)止回閥的產(chǎn)品概述
美標(biāo)止回閥又稱逆止閥(單向閥)
不銹鋼美標(biāo)止回閥的產(chǎn)品特點
①產(chǎn)品的設(shè)計制造符合美國國家標(biāo)準(zhǔn)ANSIB16.34,美國石油協(xié)會標(biāo)準(zhǔn)APl6D要求。
②美標(biāo)止回閥的閥瓣為旋啟式,流道為直通式,水平管道、垂直管道均可安裝。
③美標(biāo)止回閥的搖桿銷軸采用內(nèi)裝式結(jié)構(gòu),減少了外泄漏缺點。
④閥體,閥蓋為螺栓連接,高壓情況下(PN≥10MPa)。中法蘭采用內(nèi)壓自密封結(jié)構(gòu),使得美標(biāo)止回閥體積小,重量輕,密封可靠。
