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，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。另外，閘閥還有明桿和暗桿之分。截止閥沒有。</span>

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),不能作調(diào)節(jié)和節(jié)流。閘板有兩個(gè)密封面,常用的模式閘板閥的兩個(gè)密封面形成楔形、楔形角隨閥門參數(shù)而異,通常為50,介質(zhì)溫度不高時(shí)為2°52'。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。閘閥的種類,按密封面配置可分為楔式閘板式閘閥和平行閘板式閘閥,楔式閘板式閘閥又可分為:單閘板式、雙閘板式和彈性閘板式;平行閘板式閘閥可分為單閘板式和雙閘板式。按閥桿的螺紋位置劃分，可分為明桿閘閥和暗桿閘閥兩種。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。</span> </p><p><span style="font-size:16px;">閘閥安裝注意事項(xiàng)1.安裝前須檢查閥門腔內(nèi)和密封面等部位，不允許有污物或砂粒附著。2.各連接部位螺栓，要求均勻擰緊。3.檢查填料部位要求壓緊，既保證填料的密封性，也要保證閘板開啟靈活。4.用戶在安裝鍛鋼閘閥前，必須校對(duì)閥門型號(hào)，連接尺寸及注意介質(zhì)流向，保證與閥門要求一致性。5.用戶在安裝鍛鋼閘閥時(shí)，必須預(yù)留閥門驅(qū)動(dòng)的必要空間。6.驅(qū)動(dòng)裝置的接線須按線路圖進(jìn)行。7.鍛鋼閘閥必須定期保養(yǎng)，不得隨意碰撞及擠壓，以免影響密封。很多閥門能夠適應(yīng)多種工況，但是如果選擇不合理，閥門的性能和使用壽命會(huì)大打折扣。正確、合理的選擇閥門，首先要了解閥門各零部件的材質(zhì)適應(yīng)的工況，根據(jù)其使用范圍進(jìn)行選擇才能使其發(fā)揮比較好性能。閥體、閥蓋和閥瓣是閥門主要零件，直接承受介質(zhì)壓力，</span><span

style="font-size:16px;">閘閥閥體的流道可分為，全通徑式和縮徑式兩種。流道孔徑與閥門公稱通經(jīng)，基本相同的為全通徑式；流通孔徑比閥門公稱通經(jīng)小的稱為縮徑式?？s徑形狀有均勻縮徑和費(fèi)均勻縮徑兩種。流道呈錐管形的即是一種非均勻縮徑，這類閥門入口端的孔徑基本上與公稱通徑相同，然后逐漸縮小，至閥座處縮小到小。采用縮徑式流道（無論是錐管形非均勻縮徑或均勻縮徑），其優(yōu)點(diǎn)是同一規(guī)格的閥門，可減少閘板的尺寸、啟閉力與力矩；缺點(diǎn)是流阻增加，壓降和能耗增大，所以縮孔不宜太大。對(duì)錐管形縮徑來說，閥座的內(nèi)徑與公稱通徑之比，通常取～。公稱通徑小于250mm的縮徑閥門，其閥座內(nèi)徑一般比公稱通徑降低一檔；公稱通徑等于或大于300mm的縮徑閥門，其閥座內(nèi)徑一般比公稱通徑降低二檔。</span>
