高溫截止閥工作原理和結(jié)構(gòu)
低溫截止閥的閥桿軸線與閥座密封面垂直。閥桿開啟或關(guān)閉行程相對(duì)較短,并具有非??煽康那袛鄤?dòng)作,使得這種閥門非常適合作為介質(zhì)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?dòng)作,合得這種閥門非常適合作為介質(zhì)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(jī)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(shí)無(wú)需把整個(gè)閥門從管線上拆下來(lái),這對(duì)于閥門和管線焊接成一體的場(chǎng)合是很適用的。介質(zhì)通過(guò)此類閥門時(shí)的流動(dòng)方向發(fā)生了變化,因此截止閥的流動(dòng)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(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)。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。
