四柱式刀閘閥
four-column type knife gate valve
四柱式刀閘閥是一種新型結(jié)構(gòu)的閥門,他的結(jié)構(gòu)分軟密封和硬密封,軟密封具有活動閥座和可更換的橡膠圈組成,可以很方便的更換用損了的密封圈,而且可以根據(jù)客戶需求做成四氟密封,并且能很好的達到密封要求。*彌補了以往四氟難密封和加工不方便的不足。并且支架也是采用鑄造成型結(jié)構(gòu),使得閥門具有更好的牢固性和使用性。是造紙、工礦、污水、化工、食品領(lǐng)域*產(chǎn)品。
Four-column-type 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 .
