三、進(jìn)口電液動(dòng)刀形閘閥產(chǎn)品概述：

德國(guó)《DE LOCKE》洛克進(jìn)口電液動(dòng)刀形閘閥也叫電液動(dòng)刀閘閥，適用于帶有懸浮顆粒、纖維材料的紙漿、污水、煤漿、灰渣水泥混合物等介質(zhì)的管道，靠可以切割纖維材料的刀刃形閘板來切斷這些介質(zhì)。閥體實(shí)際上不存在腔室，閘板在側(cè)面導(dǎo)向槽內(nèi)升降，并由底部的凸耳緊壓在閥座上，如需達(dá)到較高的介質(zhì)密封性時(shí)，可選用O形密封閥座實(shí)現(xiàn)雙向密封。

3、 Introduction of imported electro-hydraulic knife gate valve products:
German "de lock" imported electro-hydraulic knife gate valve is also called electro-hydraulic knife gate valve. It is suitable for pipelines with suspended particles, fiber materials, pulp, sewage, coal slurry, ash cement mixture and other media. These media can be cut off by blade gate which can cut fiber materials. In fact, there is no chamber in the valve body. The gate rises and falls in the side guide groove, and is tightly pressed on the valve seat by the lug at the bottom. In order to achieve high medium tightness, the O-shaped sealing valve seat can be selected to achieve bidirectional sealing.

五、進(jìn)口電液動(dòng)刀形閘閥產(chǎn)品維護(hù)：

1、手輪、手柄及傳動(dòng)機(jī)構(gòu)均不允許作起吊用，并嚴(yán)禁碰撞。

2、雙閘板閘閥應(yīng)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(yīng)先打開旁通閥（以平衡進(jìn)出口的壓差及減小開啟力）。

4、帶傳動(dòng)機(jī)構(gòu)的閘閥，按產(chǎn)品使用說明書的規(guī)定安裝。

5、如果閥門經(jīng)常開關(guān)使用，每月至少潤(rùn)滑一次。

5、 Maintenance of imported electro-hydraulic 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.
