眾海消防推薦：鑄鋼閘閥的種類和用途介紹,鑄鋼閘閥的種類非常的多，不同種類的鑄鋼閘閥的用途也是不一樣的，下面鑄鋼閘閥廠家就為大家介紹一下鑄鋼閘閥的種類用途。鑄鋼閘閥是采用鑄鋼材料鑄造而成的閘閥，跟普通的閘閥一樣，它也有著多種種類。通常都是按閘閥的密封面進(jìn)行區(qū)分的，有楔式閘板式閘閥和平行閘板式閘閥。而楔式閘板式閘閥又可分為：單閘極式、雙閘板式和彈性閘板式。平行閘板式閘閥也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。鑄鋼閘閥關(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。鑄鋼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),也就是將操作轉(zhuǎn)矩變?yōu)椴僮魍屏?。主要用途：各種工業(yè)自動(dòng)化生產(chǎn)的管道流量、壓力、溫度的控制。貴州閥批發(fā)價(jià)格電動(dòng)閥/氣動(dòng)閥品牌：中國〔眾海消防〕。</p><div
