Abstract

The invention discloses an anti-clogging and low-resistance check valve, which comprises a pipeline body, flanges are coaxially fixedly connected to the openings at both ends of the pipeline body, a flow groove is opened in the pipeline body, and a flow groove is arranged in the flow groove. The top wall is vertically and fixedly connected with a baffle, and the inner bottom wall of the pipe body is vertically and fixedly connected with a vertical plate corresponding to the baffle on the side close to the flow groove, and the inner top wall of the flow groove is provided with a baffle plate. The non-return mechanism matched with the plate and the vertical plate. When the device is working, it can not only open the check normally, but also use the kinetic energy of the fluid to exert force on the lifting plate when it is opened, thereby reducing the resistance of the fluid in the pipeline body and ensuring the normal opening of the valve body. The impurities in the body are collected and automatically removed after the work is over, which improves the service life of the device, and does not need to disassemble the valve body, so the use effect is good.

Description

technical field [0001] The invention relates to the technical field of check valves, in particular to an anti-clogging and low-resistance check valve. Background technique [0002] Check valve refers to a valve whose opening and closing part is a circular disc and acts to block the reverse flow of the medium by its own weight and medium pressure. The valves in the prior art are used in different situations due to the fluid in use in different occasions. Doped with impurities, the valve will be blocked by impurities after a certain period of time, which will affect the service life of the valve, especially for the lift check valve, the valve body and disc of the lift check valve are provided with folding The groove of the flow, and the existing check valve is generally a whole, which is not easy to disassemble, so the cleaning of impurities is difficult. Contents of the invention [0003] The object of the present invention is to solve the problem that impurities are easil...
