 Use of the product 

 The axial check valve is mainly composed of parts such as valve body, valve seat, valve flap, spring, guide rod, guide sleeve and guide cover. The inlet medium pressure pushes the valve flap open, and the surface of the valve flap inlet is a circular arc. After opening, it is combined with the differ to form a spindle body to reduce the flow resistance. After stopping the pump, the inlet pressure gradually decreases. Under the action of the spring, the valve flap is closed to prevent backflow. The pressure at the outlet end gradually increases, and then the valve flap is pressed to ensure the seal of the check valve. When the valve flap is closed, it is stable, shock-absorbing, sound-absorbing, and reducing water impact.
