H42H/Y/W鑄(鍛)鋼立式止回閥產(chǎn)品概述 (保特律閥門)
H42W/H/Y嚴(yán)格按 API6D、GB/T12235 標(biāo)準(zhǔn)設(shè)計(jì)制造,本系列閥門正常處于關(guān)閉狀態(tài),由于管線中進(jìn)口端介質(zhì)的壓力作用,而克服彈簧阻力使閥門開啟。當(dāng)進(jìn)口端介質(zhì)壓力低于出口端時(shí),彈簧將閥芯推向閥座而使閥門關(guān)閉,阻止介質(zhì)逆流,故起止回作用。本閥門由于采用彈簧支撐閥芯,故采用立式安裝或臥式裝均可。本產(chǎn)品廣泛應(yīng)用于石油、化工、制藥、電力行業(yè)等各種工況的管路上。
