            锻钢截止阀有三种体减压阀盖连接设计形式：

 　　第一种是体盖螺栓连接锻钢截止阀，调节阀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锻钢截止阀，锻钢阀门按这种连接形式设计的阀门，其阀体与阀盖全焊密封，呼吸阀优点是无外泄漏。

 　　第三种是压力自紧式阀盖锻钢截止阀，针型阀按这种连接形式设计的阀门，其阀体与阀盖用螺蚊连接，内压自密封环密封，优点是内部压力越大，其密封性能越好。您可以根据实际情况合理选用阀门。

          Forged steel valve body cover to connect the design of three forms: The first is a body of forged steelScrew pumps valve cover bolt connection, according to this form of connection of valve, the valve body and valve cover bolt connection, spiral wound gasket seal,Self-priming pumps the advantage of easy maintenance. The second body of solder connectionsMagnetic pumps forged steel valve cover, according to this form of valve connection, valve cover his body with welded seal, the advantage of no external leak. A third is the pressure from tight bonnetChemical pumps forged steel valve, according to this form of connection of valve, the valve body with the valve cover to connect with Lo mosquito, Suber-water pumpsthe internal pressure from the sealing ring seal, the internal pressure of the advantage of greater the seal the better the performance. You can select the valve according to the actual circumstances reasonable.
