Z61Y锻钢焊接闸阀

上海融骏阀门锻钢闸阀有三种体盖连接设计形式。种是体盖螺栓连接，按这种连接形式设计的阀门，其阀体与阀盖用螺栓连接，缠绕式垫片密封，优点是便于维修。第二种体盖焊接连接，按这种连接形式设计的阀门，其阀体与阀盖全焊密封，优点是无外泄漏。第三种是压力自紧式阀盖，按这种连接形式设计的阀门，其阀体与阀盖用螺纹连接，内压自密封环密封，优点是内部压力越大，其密封性能越好。

rjvalve forged steel gate valve has three types of bonnet. One is bolted bonnet,which the body is connected with bonnet by
bolts and sealed by spiral gasket withadvantages of convenient maintenance; one is welded bonnet, which the body is
fullywelded with sealing bonnet of no leakage; another is pressure-in bonnet, which thebody is screwed into the bonnet and
sealed by inner pressure-in ring with bettersealing ability for higher pressure.
