上海湖泉閥門集團有限公司是一家生產J941H dn80高溫蒸汽電動法蘭截
止閥的生產廠家,它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動。閥桿的運動形式,有升降桿式(閥桿升降,手輪不升降),也有升降旋轉桿式(手輪與閥桿一起旋轉升降,螺母設在閥體上)。湖泉閥門J941Hdn80電動法蘭式截止閥屬于強制密封式閥門,所以在閥門關閉時,必須向閥瓣施加壓力,以強制密封面不泄漏。當介質由閥瓣下方進入閥門時,操作力所需要克服的阻力,是閥桿和填料的摩擦力與由介質的壓力所產生的推力,關閥門的力比開閥門的力大,所以閥桿的直徑要大,否則會發(fā)生閥桿頂彎的故障。湖泉閥門電動截止閥的介質流向就改由閥瓣上方進入閥腔,這時在介質壓力作用下,關閥門的力小,而開閥門的力大,閥桿的直徑可以相應地減少。同時,在介質作用下,這種形式的閥門也較嚴密。
