style="font-size:16px;">甘肅閘閥廠家，誠禹惠物資有限公司為您講解閘閥的知識(shí)閘閥也叫閘板閥,是一種使用的閥門。它的閉合原理是閘板密封面與閥座密封面高度光潔、平整一致,相互貼合,可阻止介質(zhì)流過,并依靠頂模、彈簧或閘板的模形,來增強(qiáng)密封效果。它在管路中主要起切斷作用。它的優(yōu)點(diǎn)是:流體阻力小,啟閉省勁,可以在介質(zhì)雙向流動(dòng)的情況下使用,沒有方向性,全開時(shí)密封面不易沖蝕,結(jié)構(gòu)長(zhǎng)度短,不僅適合做小閥門,而且適合做大閥門。閘閥按閥桿螺紋分兩類,一是明桿式,二是暗桿式。按閘板構(gòu)造分,也分兩類,一是平行,二是模式。閘閥的用途很普遍的，日常生活中也是隨處可見地存在，閘閥對(duì)我們來說并不陌生，因?yàn)樗俏覀兒人囊环N介質(zhì)，可以幫助到我們很多很多地方，那么，在生活中我們也要掌握一些閥門的知識(shí)。</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>
