碳鋼電動閘閥批發(fā)銷售的啟閉件是閘板,閘板的運動方向與流體方向相垂直,閘閥只能作全開和全關,不適合作調(diào)節(jié)和節(jié)流。閘板有兩個密封面,zui常用的楔式閘板閥的兩個密封面形成楔形,楔形角隨閥門參數(shù)而異,通常為5o。楔式閘閥的閘板可以做成一個整體,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。 閘閥關閉時,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制密封的,即閥門關閉時,要依靠外力強行將閘板壓向閥座,以保證密封面的密封性。
碳鋼電動閘閥批發(fā)銷售具有以下優(yōu)點;
1.流體阻力小,密封面受介質(zhì)的沖刷和侵蝕小。
2.開閉較省力。
3.介質(zhì)流向不受限制,不擾流、不降低壓力。
4.形體簡單,結構長度短,制造工藝性好,適用范圍廣。
