產(chǎn)品詳情
一般閥門(mén),在閥體上有方向標(biāo)志;萬(wàn)一沒(méi)有,應(yīng)根據(jù)閥門(mén)的工作原理,正確識(shí)別。截止閥的閥腔左右不對(duì)稱(chēng),流體要讓其由下而上通過(guò)閥口,這樣流體阻力小(由形狀所決定),開(kāi)啟省力(因介質(zhì)壓力向上),關(guān)閉后介質(zhì)不壓填料,便于檢修。這就是截止閥為什么不可安反的道理。其它閥門(mén)也有各自的特性。閥門(mén)安裝的位置,必須方便于操作;即使安裝暫時(shí)困難些,也要為操作人員的長(zhǎng)期工作著想。好閥門(mén)手輪與胸口取齊(一般離操作地坪1.2米),這樣,開(kāi)閉閥門(mén)比較省勁。
