Working principle of slide ball type check valve

The following image accurately and vividly expresses the slide ball type check valve. On the right is the open state of the slide ball type check valve. The valve disc of the slide ball type check valve is wrapped with a rubber ball, and it relies on the pressure of the water inlet to move along the slide to the rolling ball chamber, giving way to the flow of water; The left figure shows a closed state, with the force of the valve disc wrapping the rubber ball and the product's self gravity returning, coming out of the rolling ball chamber and blocking the conveying channel to achieve a check.
