J944H電動(dòng)角式截止閥
J944H電動(dòng)角式截止閥的啟閉件是塞形的閥瓣,密封面呈平面或錐面,閥瓣沿流體的中心線作直線運(yùn)動(dòng)。閥桿的運(yùn)動(dòng)形式,有升降桿式(閥桿升降,手輪不升降),也有升降旋轉(zhuǎn)桿式(手輪與閥桿一起旋轉(zhuǎn)升降,螺母設(shè)在閥體上)。電動(dòng)角式截止閥只適用于全開和全關(guān),不允許作調(diào)節(jié)和節(jié)流。電動(dòng)角式截止閥屬于強(qiáng)制密封式閥門,所以在閥門關(guān)閉時(shí),必須向閥瓣施加壓力,以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門時(shí),操作力所需克服的阻力,是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力,關(guān)電動(dòng)角式截止閥的力比開電動(dòng)角式截止閥的力大,所以閥桿的直徑要大,否則會(huì)發(fā)生閥桿頂彎的故障
