QJH高壓球芯截止閥的工作原理是利用閥桿帶動球芯旋轉(zhuǎn)，?實現(xiàn)閥門的開啟和關(guān)閉。?當閥門關(guān)閉時，?球芯與閥座緊密接觸，?形成密封，?阻止介質(zhì)流通；?當閥門開啟時，?球芯與閥座分離，?介質(zhì)可以順利通過閥門。?這種設(shè)計使得閥門在關(guān)閉時能夠形成有效的密封，?防止介質(zhì)泄漏，?同時在開啟時允許介質(zhì)暢通無阻地流經(jīng)閥門。?此外，?QJH高壓球芯截止閥的設(shè)計還考慮到了多種規(guī)格和型號的選擇，?以滿足不同管徑和壓力的需求，?廣泛應(yīng)用于各類液壓系統(tǒng)中，?如液壓升降機、?液壓挖掘機等。?
