2、采用可更換式密封結構，維修跟換更方便。

3、完全敞開的通道，可以防止介質在閥內的沉積。

4、閘板具有閘刀的功能，能有效的閘斷介質中各類雜物。

 

三、進口氣動帶手動刀形閘閥產品概述：

德國《DE LOCKE》洛克進口氣動帶手動刀形閘閥是具有氣動執行機構(雙層氣缸，并帶有緩沖機構)和手動及其保護機構(手動和可自鎖的氣動手動轉換裝置)的低支架明桿閘閥。該閥由于采用雙層氣缸結構，其與單氣缸式氣動閘閥相比，提升力增大了一倍。這就從根本上解決了單氣缸氣動閘閥的某些閥板在閥體內楔死而打不開的弊病。而且，由于該閥具備緩沖機構，能有效地減輕了關閉閥門時。由于活塞下行沖擊而造成的閥板密封面和閥體密封面的磨損，同時，也能避免閘板卡死的現象。

3、 The product overview of imported pneumatic valve with manual knife type valve:
The pneumatic gate valve with manual knife type imported from de lock in Germany is a low support open stem gate valve with pneumatic actuator (double cylinder and buffer mechanism) and manual and its protection mechanism (manual and self-locking pneumatic manual transfer device). Because of the double cylinder structure, the lifting force of the valve is doubled compared with the single cylinder pneumatic gate valve. This fundamentally solves the disadvantage that some valve plates of single cylinder pneumatic gate valve can not be opened without wedge in the valve body. Moreover, because the valve has buffer mechanism, it can effectively reduce the closing of the valve. The valve plate sealing surface and valve body sealing surface are worn due to the downward impact of piston, and the phenomenon of ram sticking can also be avoided.
 

四、進口氣動帶手動刀形閘閥產品維護：

1、手輪、手柄及傳動機構均不允許作起吊用，并嚴禁碰撞。

2、雙閘板閘閥應垂直安裝（即閥桿處于垂直位置，手輪在頂部）。

3、帶有旁通閥的閘閥在開啟前應先打開旁通閥（以平衡進出口的壓差及減小開啟力）。

4、帶傳動機構的閘閥，按產品使用說明書的規定安裝。

5、如果閥門經常開關使用，每月至少潤滑一次。

4、 Maintenance of imported pneumatic valve with manual knife gate valve:
1. Hand wheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
2. The double gate valve should be installed vertically (i.e. the stem is in the vertical position and the hand wheel is at the top).
3. The gate valve with bypass valve should be opened before opening (to balance the pressure difference between the inlet and outlet and reduce the opening force).
4. The gate valve with transmission mechanism shall be installed according to the product manual.
5. If the valve is used frequently, lubricate it at least once a month.
