GQ947Y電動軌道球閥的詳細資料：

GQ947Y電動軌道球閥是新型實用產(chǎn)品，具有旋轉(zhuǎn)球芯90度擺切斷的一種新型球閥。國內(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行開與關(guān)，經(jīng)常導(dǎo)致密封面損壞，閥門泄漏和卡死現(xiàn)象，軌道球閥就是針對上述常見缺陷進行更新設(shè)計使球芯旋轉(zhuǎn)90度再開關(guān)的新型球閥，該球閥能使密封面無摩擦結(jié)合，達到無泄漏的安全目的，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

　　傳統(tǒng)的球閥，無論是浮動式或固定式，球體與閥座始終接觸，開關(guān)扭矩大，密封面容易損傷，軌道球輪著啟閉時，球體先偏轉(zhuǎn)-δ角，然后轉(zhuǎn)動，開關(guān)全過程中球體與閥座脫離，故閥座不會被擦傷，并且啟閉扭矩小。
