Preferably, a reinforcing rib b is arranged between the limiting rod and the lower surface of the valve core, so that the structural strength of the limiting rod is improved.

Preferably, a protruding limiting block is arranged on the edge of the valve core at the position farthest away from the pin, after the check valve is closed, the limiting block abuts against the convex ring, the valve core is erected on the convex ring through the pin and the limiting block instead of the pin, and the diameter of the valve core can be reduced.

Preferably, the thickness of the limiting block is obviously larger than that of the valve core, so that the weight increasing effect is achieved, and the valve core is convenient to fall down when being closed.

Preferably, the upper surface of the valve core, which is far away from the limiting block, is provided with a weight reduction groove.

Preferably, the valve core, the pin and the limiting rod are integrally formed. The check valve is made of PC material, and the material intensity is big, has certain toughness, and easily machine-shaping.

The beneficial effects of the utility model reside in that: energy loss when opening can effectively reduce rivers through the check valve improves the hydraulic performance of water pump, and when the water pump shut down, the case is closed by oneself under the action of gravity, and the water of backward flow slowly flows down through the discharge groove of case, and the check valve case uses the PC material to make, and this material intensity is big, has certain toughness, and easily machine-shaping.
