style="text-indent:25px">美標(biāo)閘閥關(guān)閉時(shí)，密封面可以只依靠介質(zhì)壓力來密封，即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強(qiáng)制密封的 , 即閥門關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座，以保證密封面的密封性。閘閥的閘板隨閥桿一起作直線運(yùn)動(dòng)的，叫升降桿閘閥( 亦叫明桿閘閥)。通常在升降桿上有梯形螺紋，通過閥門頂端的螺母以及閥體上的導(dǎo)槽，將旋轉(zhuǎn)運(yùn)動(dòng)變?yōu)橹本€運(yùn)動(dòng) ,

, 再倒回 1/2-1圈 , 作為全開閥門的位置。因此，閥門的全開位置，按閘板的位置(即行程>來確定。不銹鋼閘閥,鍛鋼閘閥,法蘭閘閥,法蘭球閥,二片式球閥有的閘閥，閥桿螺母設(shè)在閘板上，手輪轉(zhuǎn)動(dòng)帶動(dòng)閥桿轉(zhuǎn)動(dòng) , 而使閘板提升 ,

閥門是連接方式為法蘭的閘閥，這種連接方式為常見。法蘭閘閥在管路中使用時(shí)穩(wěn)定可靠。特點(diǎn)：流體阻力小，閘閥閥體內(nèi)部介質(zhì)通道是直通的，介質(zhì)流經(jīng)閘閥時(shí)不改變其流動(dòng)方向，因而流動(dòng)阻力較小。啟閉較省力，啟閉時(shí)閘板運(yùn)動(dòng)方向與介質(zhì)流動(dòng)方向相垂直，與截止閥相比、閘閥的啟閉較為省力。介質(zhì)流動(dòng)方向一般不受限制。介質(zhì)可從閘閥兩側(cè)任意方向流過，均能達(dá)到接通或截?cái)嗟哪康?。便于安裝，適用于介質(zhì)的流動(dòng)方向可能改變的管路中。</p><p style="text-indent:25px">鉻鉬鋼閘閥的啟閉件是閘板，閘板的運(yùn)動(dòng)方向與流體方向相垂直，閘閥只能作全開和全關(guān)，不能作調(diào)節(jié)和節(jié)流。楔式閘閥的閘板可以做成一個(gè)整體，叫做剛性閘板;也可以做成能產(chǎn)生微量變形的閘板，以改善其工藝性，彌補(bǔ)密封面角度在加工過程中產(chǎn)生的偏差，這種閘板叫做彈性閘板。鉻鉬鋼閘閥的開啟和關(guān)閉由電動(dòng)裝置來控制，電動(dòng)裝置分別配有**電機(jī)、減速器、轉(zhuǎn)矩控制機(jī)構(gòu)，現(xiàn)場操作機(jī)構(gòu)，手動(dòng)、電動(dòng)切換機(jī)構(gòu)。除就地操作外，還可進(jìn)行遠(yuǎn)距離操作。電站匣閥安裝時(shí)帶有旁通閥的閘閥在開啟前應(yīng)先打開旁通閥（以平衡進(jìn)出口的壓差及減小開啟力）。</p><div
