I. Introduction of H44N Swing Check Valve

H44N Swing Check Valve Structure

采用内装摇臂旋启式结构,阀门的所有启闭件都装于阀体内部,不穿透阀体,除了中法兰部位用密封垫片和密封环外,整体没有外漏点,杜绝阀门外泄的可能。 H44N swing check valve adopts built-in swing arm swing check structure. All opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body. Except for the gasket and seal ring in the middle flange, There is no leakage point, preventing the possibility of leakage of the valve. The sealing surface is made of elastic nylon material or polytetrafluoroethylene, which improves the sealing performance and avoids the electrostatic spark caused by the impact of the medium pressure. 适用燃气管道接通和截断管路介质的启闭装置。 H42N vertical check valve is applicable to the opening and closing device for gas pipeline to connect and cut off the pipeline medium. Has been widely used in chemical, metallurgy, pharmaceutical and other fields.
