平板閘閥的產品結構特點Productsdesignfeatures ●閥體有鑄造和焊接兩種結構。
Castandweldtwostructureswiththebody
●閥座采用O形密封圈密封和施加預緊力的浮動閥座結構，使閥門進出口雙向密封；并且該結構的啟閉力矩僅為普通閥門的1/2，能達到輕松開、關閥門。

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

●金屬對金屬密封的閥門，閥體外部設有注油脂結構，油脂通過注脂器、閥座進入閥門密封面，使閥門達到零泄漏。

●帶導流孔閥門的閘板，無論是全開或是全關始終與密封面吻合，密封面得到保護不受介質直接沖刷，從而延長使用壽命。

●閥門在全開時，通道平滑為直線，流阻系數極小，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構，無需經常調節，開、關極為輕便，且密封性可靠，填料函處設有輔助密封油脂注入結構，密封性能 可靠，真正達到零泄漏；解決了通用閥門填料處最容易外漏的蔽病。

●閥門關閉時能自動卸掉內腔高壓（詳見工作原理圖），保證使用安全。
