High Quality Pn40 Throttle Check Valve for Air Compressor High Quality Pn40 Throttle Check Valve for Air Compressor High Quality Pn40 Throttle Check Valve for Air Compressor 1. The opening and closing principle of swing check valve is the same as that of lifting check valve, which also depends on the action of fluid pressure and the weight of the valve disc. The difference is that the opening and closing way of the valve disc is rotating motion rather than moving up and down, and the inlet direction of the fluid should be on the side that can impact the rotation of the valve disc.

2. The closing part of swing check valve is a disc or disc equivalent to the diameter of the pipeline. It is suspended in the valve chamber.
High Quality Pn40 Throttle Check Valve for Air Compressor When the fluid medium in the pipeline is active, a thrust will occur in the fluid medium. The thrust will push the two discs of the wafer check valve, and the valve will be opened, and the medium will flow smoothly. When the medium in the pipeline stops moving, perhaps in a stopped state, the two valve disc in its own component and spring kneading force together under the closed force. When the valve disc is closed, the media in the pipeline backflow phenomenon, the backflow of the media on the valve disc reverse thrust and the gravity of the valve disc itself, the valve disc will be tightly kneaded and sealed surface fit, prevent the attack of the media backflow.
High Quality Pn40 Throttle Check Valve for Air Compressor The rubber ball in the ball cover for short stroke rolling to realize the valve opening and closing. When the water pump starts, the water under the action of pressure flushes the rubber ball, so that the rubber ball rolls to the right side, the position is fixed by the conical body in the back valve body, the check valve is opened; After the pump stops, due to the return water pressure in the piping system, the rubber ball is forced to roll to the left front valve body to reach the closing of the check valve.
