Description
Technical Field
The utility model relates to the field of check valves, in particular to a high-pressure diversion check valve.
Background
The check valve is mainly used for medium circulation and preventing the damage of the pump and the driving motor caused by medium backflow in a pipeline system. In practical application, the three-large performance pressure drop, the minimum full-open flow rate and the water-hammer prevention function of the check valve are important technical indexes for measuring the check valve.
The sealing of the valve seat is realized by pressing the gasket through the threaded connection of the valve seat and the valve body, so that the sealing is realized, however, the sealing can be realized by carbon steel, and the sealing is not tight if the sealing is made of stainless steel, because the stainless steel threads can be bitten, and the sealing is not tight.
