Abstract

The invention discloses a non-return valve with high impact resistance and wear resistance. The non-return valve comprises a valve body which is of a hollow structure, wherein a water inlet is formedin the side wall of one side of the valve body; a first baffle ring is arranged on the inner wall of the water inlet; a movable rod which is transversely arranged is arranged in the valve rod; a baffle plate is arranged on the side wall of one side of the movable rod; one side, away from the movable rod, of the baffle plate abuts against the side wall of the first baffle ring; a water outlet is formed in one side, away from the water inlet, of the valve body; a second baffle ring is arranged on the inner wall of the water outlet; a first fixed block which is vertically arranged is arranged onthe side wall of one side of the second baffle ring; the first fixed block is in fastening connection with the second baffle ring through a bolt; a plurality of first through holes are formed in the side wall of one side of the first fixed block in a surrounding mode; and a sleeve rod which is transversely arranged is arranged on the side wall of the center of the first fixed block. The non-returnvalve with high impact resistance and wear resistance is relatively high in impact resistance and wear resistance, and can prolong the service life.

Description

Technical field [0001] The invention relates to the technical field of check valves, in particular to a check valve with high impact resistance and wear resistance. Background technique [0002] Check valve refers to the valve that automatically opens and closes the disc depending on the flow of the medium itself to prevent the medium from flowing back. It is also called check valve, one-way valve, reverse flow valve, and back pressure valve. Check valve is a kind of automatic The main function of the valve is to prevent the medium from flowing backward, to prevent the pump and the drive motor from reversing, and to discharge the container medium. The existing check valve is generally made of plastic, so its impact resistance and wear resistance are relatively poor, and it cannot adapt to high-pressure pipelines. For this reason, we propose a check valve with high impact and wear resistance to solve the above problems. Summary of the invention [0003] The purpose of the present...
