精品Q21F-64P外螺紋對(duì)焊接式氣源球閥
一,Q21F,Q21SA外螺紋球閥的作用:Q21F,Q21SA外螺紋球閥,主要是鍛鋼鍛造制造工藝,螺紋采用數(shù)控車床精成而成,它的關(guān)閉件是一個(gè)球體,球體繞閥體中心線旋轉(zhuǎn)來達(dá)到開啟,關(guān)閉的目的,主要作用是用來切斷,分配和改變介質(zhì)的流向
二,Q21F,Q21SA外螺紋球閥的工作原理:關(guān)閉時(shí)逆時(shí)針轉(zhuǎn)動(dòng)手柄,手柄通過閥桿轉(zhuǎn)動(dòng)球閥的球體,讓球在閥座內(nèi)旋轉(zhuǎn),當(dāng)手柄旋轉(zhuǎn)90度時(shí),球體也旋轉(zhuǎn)了90度,從而讓球體跟中間的密封圈一起,堵住閥體的通道,達(dá)到關(guān)閉的目的。開啟時(shí)順時(shí)針轉(zhuǎn)動(dòng)手柄,手柄通過閥桿轉(zhuǎn)動(dòng)球閥的球體,讓球體在閥座內(nèi)旋轉(zhuǎn),當(dāng)順時(shí)針轉(zhuǎn)到90度時(shí),球體的中心孔剛好對(duì)準(zhǔn)閥體的通道,從而流體可以通過閥體和球,達(dá)到開啟的目的。
