www.huyifamen.com        GQ947Y電動(dòng)軌道球閥是新型實(shí)用產(chǎn)品,具有旋轉(zhuǎn)球芯90度擺切斷的一種高科技型球閥。 國(guó)內(nèi)目前所用Q型球閥均是在給定預(yù)緊力下球芯與閥座摩擦進(jìn)行開(kāi)與關(guān),經(jīng)常導(dǎo)致密封面損壞,閥門泄漏和卡死現(xiàn)象,軌道球閥就是針對(duì)上述常見(jiàn)缺陷進(jìn)行更新設(shè)計(jì)使球芯旋轉(zhuǎn)90度再開(kāi)關(guān)的新型球閥,該球閥能使密封面無(wú)摩擦結(jié)合,達(dá)到無(wú)泄漏的安全目的,并大大提高了閥門的使用壽命。一、GQ947H軌道球閥結(jié)構(gòu)特點(diǎn)
傳統(tǒng)的球閥,無(wú)論是浮動(dòng)式或固定式,球體與閥座始終接觸,開(kāi)關(guān)扭矩大,密封面容易損傷,軌道球輪著啟閉時(shí),球體先偏轉(zhuǎn)-δ角,然后轉(zhuǎn)動(dòng),開(kāi)關(guān)全過(guò)程中球體與閥座脫離,故閥座不會(huì)被擦傷,并且啟閉扭矩小。二、GQ947H軌道球閥主要零件材料
