電動法蘭刀閘閥PZ941H-16P介紹
一、電動法蘭刀閘閥PZ941H-16P,刀型閘閥的啟閉件是閘板,閘板的運(yùn)動方向與流體方向相垂直,手動刀型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,zui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,楔式刀型閘閥的閘板可以做成一個(gè)整體,叫做剛性閘板;可做成能產(chǎn)生微量變形的閘板改善其工藝性,彌補(bǔ)密封面角度在加工過程中產(chǎn)生的偏差,叫彈性閘板 刀型閘閥關(guān)閉時(shí)密封面可依靠介質(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,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。
二、具有以下優(yōu)點(diǎn);
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(jié)構(gòu)長度短,制造工藝性好,適用范圍廣。
