Description

Self-cleaning type efficient check valve

Technical Field

The invention relates to the technical field of check valves, in particular to a self-cleaning efficient check valve.

Background

The check valve is mainly divided into a swing check valve (rotating according to the gravity center) and a lifting check valve (moving along the axis), and the check valve only allows the medium to flow in one direction and prevents the medium from flowing in the opposite direction. Typically such valves are self-acting, with the flap opening under the pressure of a fluid flowing in one direction; when the fluid flows in the opposite direction, the valve flap is combined by the fluid pressure and the self-weight of the valve flap to act on the valve seat, thereby cutting off the flow. When the medium flows reversely, the valve clack is closed and closed by the sealing surface of the valve clack and the valve seat due to the self weight of the valve clack and the reverse force of the medium, thereby achieving the purpose of preventing the medium from reversely flowing; however, in the practical application process, because the check valve adopts the single valve plate assembly, the structure is simple, the problem of leakage backflow caused by the fact that the conveyed material is blocked or the diaphragm is damaged by the medium is solved, the check valve cannot work normally, the service life of the valve is greatly reduced, therefore, the check valve needs to be maintained and replaced frequently, the use cost is increased, compared with the design provided by the application number 201520146027.1, the design can open the air blowing valve and the air outlet valve when the material is blocked, compressed air is introduced from the air outlet, the material is driven to be discharged from the air outlet together, the self-cleaning function of the check valve is realized, but the design can change the internal pressure when the air is introduced, for some sensitive materials, the material performance can be influenced by the large air pressure difference, and therefore the use limitation is large.
