QZ型电动刀闸阀

QZ type electric knife gate valve

此阀是一种新型结构的阀门，他的结构分软密封和硬密封，软密封具有活动阀座和可更换的橡胶圈组成，可以很方便的更换用损了的密封圈，而且可以根据客户需求做成四氟密封，并且能很好的达到密封要求。*弥补了以往四氟难密封和加工不方便的不足。并且支架也是采用铸造成型结构，使得阀门具有更好的牢固性和使用性。是造纸、工矿、污水、化工、食品领域*产品。该阀门配电动执行器可实现远程微电脑控制。在电源供应中断时，也可以通过手动来操作阀门启闭，从而紧急控制了介质的流向，也避免了事故的发生。也可以使用现场电控箱、远程PLC电动智能控制等附件来操作和调试的控制。用户可根据实际需要进行选择。

Electric knife gate valve that includes soft seal and hard seal is a new structure .Soft seal with activities seat and changeable rubber ring can easily replace damaged seal ring to achieve sealing requirement well , and can be made of PTFE seals according to customer's demands. It compley makes up for past PTFE difficult to seal and processing inconvenient ,and yoke is cast into a model using structure to make valve better robustness and usability. It's suitable for paper making, mining, sewage, chemical industry, food industry .This valve with electric actuator can realize remote microcomputer control. When power is cut off ,it also can be operated by manual to control the flow of media to avoid accidents . You can also use electric control box, remote PLC inligent control ,etc,to operate and debug control. Users can choose according to the their needs.
