高溫截止閥是指關閉件(閥瓣)沿閥座中心線移動的閥門。根據(jù)閥瓣的這種移動形式,閥座通口的變化是與閥瓣行程成正比例關系。由于該類閥門的閥桿開啟或關閉行程相對較短,而且具有非??煽康那袛喙δ埽钟捎陂y座通口的變化與閥瓣的行程成正比例關系,非常適合于對流量的調(diào)節(jié)。因此,這種類型的閥門非常適合作為切斷或調(diào)節(jié)以及節(jié)流使用。

高溫截止閥工作原理和結構
低溫截止閥的閥桿軸線與閥座密封面垂直。閥桿開啟或關閉行程相對較短,并具有非??煽康那袛鄤幼?,使得這種閥門非常適合作為介質的切斷或調(diào)節(jié)及節(jié)流使用。
高溫截止閥的閥瓣一旦處于開啟狀況,它的閥座和閥瓣密封面之間就不再的接觸,并具有非??煽康那袛鄤幼?,合得這種閥門非常適合作為介質的切斷或調(diào)節(jié)及節(jié)流使用。
高溫截止閥一旦處于開啟狀態(tài),它的閥座和閥瓣密封面之間就不再有接觸,因而它的密封面機械磨損較小,由于大部分截止閥的閥座和閥瓣比較容易修理或更換密封元件時無需把整個閥門從管線上拆下來,這對于閥門和管線焊接成一體的場合是很適用的。介質通過此類閥門時的流動方向發(fā)生了變化,因此截止閥的流動阻力較高于其它閥門。
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)。截止閥只適用于全開和全關,不允許作調(diào)節(jié)和節(jié)流。
