Product Introduction

Ball check valve is a kind of check valve with multi-ball, multi-channel, multi-cone inverted flow structure, which is mainly composed of front and rear valve bodies, rubber balls, and cones. Its working principle is: the rubber ball rolls in the ball cover for a short stroke to realize the opening and closing of the valve. When the water pump starts, the water blows open the rubber ball under the action of pressure, so that the rubber ball rolls to the right. The cone in the rear valve body fixes its position, and the check valve opens; after the pump stops, due to the pressure in the pipeline system The back water pressure forces the rubber ball to roll to the front valve body on the left side to close the check valve.
