J661W氣動對焊截止閥 
    zui高工作溫度:-29~+300℃ 
     
J661W氣動對焊截止閥 適用介質(zhì):水.蒸汽.熱油等 
 閥門功能特點(diǎn)：本閥門是一種（分雙作用/單作用）雙重的密封設(shè)計(jì)（波紋管+填料）若波紋管失效，閥桿填料也會避免泄露，保證閥桿的零泄露，提供無需維修條件，安裝時(shí)必須注意閥門流向道標(biāo)志（單作用流道方向高進(jìn)低出，雙作用流道方向低進(jìn)高出） 
     工作原理 單作用（WZHBG型）氣開型的氣動波紋管切斷閥，在工作狀態(tài)電磁閥通電打開氣源閥門開閥，即斷電，電磁閥自動排氣執(zhí)行器內(nèi)彈簧力作用自動關(guān)閉，與遠(yuǎn)距離的控制臺（微機(jī)）配套使用，利用氣源控制閥門的開啟和關(guān)閉。 
     
     當(dāng)事故發(fā)生時(shí)，閥門線圈瞬時(shí)斷電，觸發(fā)二位三通電磁閥快速排氣并進(jìn)入關(guān)閉狀態(tài)。此時(shí)，即使撤區(qū)電源.氣源,閥門仍處于關(guān)閉狀態(tài),不會重新自動打開 
     
     當(dāng)工作人員處理事故時(shí),必須是無氣源壓力,無電源的狀態(tài)下進(jìn)行維修,事故處理完工后,人工重新開啟閥門,才會恢復(fù)供氣,即通電通氣 
     
     閥門采用先導(dǎo)式閥瓣,開啟輕松靈活,即使壓力達(dá)到1.6Ppa開啟也十分輕松,當(dāng)執(zhí)行器給壓時(shí)節(jié),先導(dǎo)閥開啟,當(dāng)執(zhí)行器卸壓時(shí)本閥處動關(guān)閉,本閥采用止回閥原理,只能單向截?cái)?安裝時(shí)必須注意閥門流向道標(biāo)志（本閥流道方向高進(jìn)低出） 
     
     雙作用（WZPQ型） 氣開/氣關(guān)式,利用電磁閥控制氣源,氣源進(jìn)入上部閥門的關(guān)閉,氣源進(jìn)入下部閥門的開啟,并與遠(yuǎn)距離的控制臺配套利用電源控制閥門的開啟和關(guān)閉
