電動截止閥結(jié)構(gòu)特點:
1、 啟閉無摩擦。這一功能完全解決了傳統(tǒng)閥門因密封面之間相互摩擦而影響密封的問題。
2、 上裝式結(jié)構(gòu)。對裝在管道上的閥門可直接在線檢查與維修,能有效減少裝置停車,降低成本。
3、 單閥座設計。消除了閥門中腔介質(zhì)因異常升壓而影響使用安全的問題。
4、 低扭矩設計。特殊結(jié)構(gòu)設計的閥桿,只需配一個小手把閥門就能輕松啟閉。
5、 楔形密封結(jié)構(gòu)。閥門是靠閥桿提供的機械力,將球楔壓到閥座上而密封,使閥門的密封性不受管線壓差變化的影響,在各種工況下密封性能都有可靠保證。
6、 密封面的自清潔結(jié)構(gòu)。當球體傾離閥座時,管線中的流體沿球體密封面成360°均勻通過,不僅消除了高速流體對閥座局部的沖刷,也沖走了密封面上的聚積物,達到自清潔的目的。
7、 閥門口徑DN50以下的閥體、閥蓋是模鍛件、DN65以上的閥體、閥蓋是鑄鋼件。
8、 閥體與閥蓋的連接形式各有不同、夾箍銷軸式連接、法蘭墊片連接和自密封螺紋連接。
9、 閥座、閥瓣密封面均采用等離子噴焊或堆焊鈷鉻鎢硬質(zhì)合金,密封面硬度高、耐磨、抗擦傷、使用壽命長。
10、閥桿材料為滲氮鋼、滲氮后的閥桿表面硬度高、耐磨、抗擦傷、同時防腐蝕、使用壽命長。
