style="font-size:16px;">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)，不適門參數(shù)而異,通常為5°,介質(zhì)溫度不高時(shí)為2°52‘。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。閘門介紹閘閥關(guān)閉時(shí)，密封面可以只依靠介質(zhì)壓力來密封，即只依靠介質(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。運(yùn)動(dòng)方式：閘閥的閘板隨閥桿一起作直線運(yùn)動(dòng)的，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),也就是將操作轉(zhuǎn)矩變?yōu)椴僮魍屏?。開啟閥門時(shí)，當(dāng)閘板提升高度等于閥門通徑的1：1倍時(shí)，流體的通道完全暢通，但在運(yùn)行時(shí)，此位置是無法監(jiān)視的。實(shí)際使用時(shí)，是以閥桿的頂點(diǎn)作為標(biāo)志，即開不動(dòng)的位置，作為它的全開位置。為考慮溫度變化出現(xiàn)</span><span

style="font-size:16px;">閘閥的特點(diǎn)和用途：閘閥的優(yōu)點(diǎn)是流動(dòng)阻力小，開閉較省力，不受介質(zhì)流向的限制，介質(zhì)可以兩個(gè)方向流動(dòng)，結(jié)構(gòu)尺寸較小，全開時(shí)密封面受介質(zhì)沖蝕小。缺點(diǎn)是結(jié)構(gòu)復(fù)雜，高度尺寸較大，開啟需一定的空間，開閉時(shí)間長(zhǎng)，開閉時(shí)密封面容易受沖蝕和擦傷。閘閥的應(yīng)用范圍是由其特點(diǎn)決定的，一般用于公稱通徑大于100mm的管道上，作切斷作用。閘閥可依靠介質(zhì)壓力緊緊與密封面緊閉，從而達(dá)到不泄露的效果。當(dāng)啟閉時(shí)閥芯和閥座密封面始終接觸并相互磨擦，因此密封面容易磨損，閘閥處于接近關(guān)閉時(shí)，管道前后壓差很大，使密封面磨損更加嚴(yán)重。閘閥的結(jié)構(gòu)會(huì)比截止閥更復(fù)雜，從外形來看，同口徑情況下，閘閥要比截止閥高，截止閥要比閘閥長(zhǎng)。另外，閘閥還有明桿和暗桿之分。截止閥沒有。</span>
