平板閘閥的產(chǎn)品結(jié)構(gòu)特點(diǎn)Productsdesignfeatures ●閥體有鑄造和焊接兩種結(jié)構(gòu)。
Castandweldtwostructureswiththebody
●閥座采用O形密封圈密封和施加預(yù)緊力的浮動(dòng)閥座結(jié)構(gòu)，使閥門進(jìn)出口雙向密封；并且該結(jié)構(gòu)的啟閉力矩僅為普通閥門的1/2，能達(dá)到輕松開、關(guān)閥門。

●閥座采用密封面上鑲嵌PTFE，具有PTFE對(duì)金屬和金屬對(duì)金屬的雙重密封，PTFE密封面同時(shí)清除閘板臟物的作用，

●金屬對(duì)金屬密封的閥門，閥體外部設(shè)有注油脂結(jié)構(gòu)，油脂通過注脂器、閥座進(jìn)入閥門密封面，使閥門達(dá)到零泄漏。

●帶導(dǎo)流孔閥門的閘板，無論是全開或是全關(guān)始終與密封面吻合，密封面得到保護(hù)不受介質(zhì)直接沖刷，從而延長(zhǎng)使用壽命。

●閥門在全開時(shí)，通道平滑為直線，流阻系數(shù)極小，無壓力損失，可通毛球清掃管線。

●本閥采用帶自密封能力的填料結(jié)構(gòu)，無需經(jīng)常調(diào)節(jié)，開、關(guān)極為輕便，且密封性可靠，填料函處設(shè)有輔助密封油脂注入結(jié)構(gòu)，密封性能 可靠，真正達(dá)到零泄漏；解決了通用閥門填料處最容易外漏的蔽病。
