进口刀型闸阀产品优势-德国洛克

 

进口刀型闸阀结构特点:

刀型闸阀顾名思义就是平板阀板底部具有刀型斜切口，具有切断介质的功能，使得阀门关闭不受介质阻塞。此阀门一般用于纸浆、煤灰、化工原料、污水、食品等介质的流通启闭。压力范围一般都1.6MPa以内使用，温度一般在120℃以下使用，高温也可以用特殊材质代替使用。根据密封性能要求可以分软密封和硬密封。软密封可以达到0泄露，硬密封根据不同泄露等级检验。

该阀门操作方便,开启自由,运动灵活可靠; 阀瓣装配维修简单, 密封结构合理, 密封圈更换方便实用。

进口刀型闸阀工作原理:

 刀闸阀关闭时,密封面可以只依靠介质压力来密封,即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封,这就是自密封.大部分闸阀是采用强制密封的,即阀门关闭时，要依靠外力强行将闸板压向阀座,以保证密封面的密封性。

Working principle of imported knife gate valve:
When the knife gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, the medium pressure will press the sealing surface of the gate valve to the seat on the other side to ensure the sealing surface, which is self sealing. Most gate valves adopt forced sealing, that is, when the valve is closed, the gate valve should be pressed to the seat by external force to ensure the sealing surface tightness.
                                                                               

进口刀闸阀安装须知:

1.安装前须检查阀门腔内和密封面等部位，不允许有污物或砂粒附着；

2.各连接部位螺栓,要求均匀拧紧；

3.检查填料部位要求压紧，既保证填料的密封性，也要保证闸板开启灵活；

4.用户在安装阀门前，必须校对阀门型号，连接尺寸及注意介质流向，保证与阀门要求一致性；

5.用户在安装阀门时，必须预留阀门驱动的必要空间；

6.驱动装置的接线须按线路图进行；

7.刀型闸阀必须定期保养，不得随意碰撞及挤压，以免影响密封。

Instructions for installation of imported knife gate valve:
1. Check the valve cavity and sealing surface before installation, and no dirt or sand is allowed to adhere to them;
2. The bolts of each connecting part shall be tightened evenly;
3. Check the packing position to ensure the tightness of the packing and the flexible opening of the ram;
4. Before installing the valve, the user must check the valve model, connection size and medium flow direction to ensure the consistency with the valve requirements;
5. When installing the valve, the user must reserve the necessary space for valve driving;
6. The wiring of driving device shall be carried out according to the circuit diagram;
7. The knife gate valve must be maintained regularly. It is not allowed to collide and squeeze at will, so as not to affect the seal.
