平板閘閥產品結構特點Products design features

  ●閥體有鑄造和焊接兩種結構。
   Cast and weld two structures with the body

  ●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。
   The seal ring uses the floating seat ring structure with o-sear ring sealed and pre-tightening force applied to have inlet and outlet dual-way sealed;and the open-close moment with this structure is 1/2 that of the common valves only,able to lightly open and close valves.

  ●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,
   The seat ring uses the sealing face inlaid with PTFE,so has dual seals of PTFE to metal and metal to metal, the PTFE sealingface also acts as removing the dirt on the wedge disc.

  ●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。
   For the valve with the metal to metal seal,there is grease injector outside of it,grease gets into the sealing face through the injector and the seat ring to have the valve up to null leak.

  ●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?;げ皇芙櫓手苯映逅?,從而延長使用壽命。
   The wedge disc of the valve with flow guide hole is always fitted with the sealing face whether in full open or full close status to have the sealing face protected without being directly eroded by the medium so as to extend the duration.

  ●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。
   When fully opened,the valve's channel is smooth and linear ,with an extremely small flow resisting coefficient and no pressure loss,and the pipeline can be cleaned with hair-ball through it.

  ●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,密封性能絕對可靠,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。
   This valve uses the packing structure with the ability of self-seal,needs no constant adjustment,features very light open and close and a reliable seal An assisting sealing grease injection structure is set in the packing to have the sealing performance absolutely reliable and get a true null leak,settling the problem for the packing place of universal valves to be easiest leak outward.

       ●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。
   Automatic removal of the high pressure in the internal cavity when the valve is about to close(see the working principle diagram)for the details) so as to ensure safety.

  ●全封閉結構,防護性能好,可適應全天候要求。
   Fully sealed structure leaves a good protective property,suitalbe for the requirement of 24-hour duty.

  ●升降桿閥門設有指示桿或觀察窗以表示閥門的啟閉情況,旋轉桿閥門采用封閉齒輪轉動啟閉指示機構。
   An indication rod or viewing window is set Ascend and descend stemwith the valve to whow the open-close condition,Revolve stem with the valve Use a sealed gear-driving open-close indicating mechansim.

  ●直理式閥門外表面采用環氧煤瀝青防腐處理,能與管線同壽命。
   The external surface of the directly built-in valve is corrosion resisting treated with epoxy coal bitumen and can be the same duration as the pipeline.
