The difference between the two constitutes the sealing force between the valve disc and the valve seat, so that the valve disc is tightly pressed against the valve seat, and the medium of the equipment cannot be discharged. When the pressure in the equipment exceeds the regular working pressure and reaches the opening pressure of the valve, the inside The force exerted by the medium on the valve flap is greater than the force exerted by the loading tissue on it, so the valve flap leaves the valve seat.

Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis), installation method edit 1, the disc of the check valve is disc-shaped, and the passage around the valve seat The rotating shaft of the valve rotates. Because the channel in the valve is streamlined, the flow resistance is smaller than that of the rising butterfly check valve. It is suitable for the occasion of low flow velocity and infrequently changing gate diameter.

It is widely used in coal chemical, petrochemical, rubber, paper, pharmaceutical and other pipelines as a media splitting, confluence or flow switching device. [1] The structure and working principle of the buckle door: consists of valve seat, valve plate, dense soil sealing ring, and hinge It consists of four parts and is only used for round and square water outlets with one-way water flow.
