四柱式伞齿轮刀闸阀
four-column type pneumatic knife gate valve
四柱式伞齿轮刀闸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。
Four-column-type bevel gear 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 castted into a model using structure to make valve better robustness and usability. It's suitable for paper making, mining, sewage, chemical industry, food industry .
