锻钢截止阀的优点及连接形式

译文：
锻钢截止阀有三种体盖连接设计形式： 第一种是体盖螺栓连接锻钢截止阀，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，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锻钢截止阀，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。

原文：
Forged Globe Valve There are three forms of body cover to connect the design: The first is the body of Y-type bellow seal stop valve acc. to DINforged steel valve cover bolt connection, according to the design of the valve to connect the form of its body with the valve cover bolt connection, spiral wound gasket seal, the advantage of easy maintenance. The second body cover welded Right angle bellow stop valve acc. to DINconnections forged steel globe valve, according to the design of such connections forms of valves, valve cover his body with all-welded seal, the advantage of no external leak. The third is the pressure of self-tight globe valve forged steel valve cover, according to the design ofQJ-1A stop valve for pneumatic line such connections forms the valve, the valve body with the valve cover with the screw mosquito connected pressure from the seal ring seal, the greater the advantage of internal pressure, its better sealing performance. You can use the valve according to the actual circumstances which reasonably.
