Therefore, the anti-hooking flap check valve is provided.

Disclosure of Invention

In view of the above situation, the present invention provides a one-way valve for preventing hooking and turning over a plate, which is installed in a drainage and pollution discharge facility, when the one-way valve is opened, the edge of the upper end of the turning over plate can be hidden outside the cylinder body, thereby avoiding hooking and catching sundries in the drainage and pollution discharge process.

The technical solution of the invention is as follows: the anti-hooking turnover plate one-way valve comprises a cylinder, a turnover plate and a force application mechanism, wherein a leak hole is formed in the cylinder, the turnover plate and the cylinder form a turnover structure through a shaft, and the turnover plate is kept in close contact with the edge of the leak hole in the cylinder by the force application mechanism in a non-discharge state; the position of the shaft is positioned outside the cylinder body, so that the edge of the upper end of the turning plate is shielded by the cylinder body in the opening process, and a drainage and pollution discharge area is avoided.

Preferably, the shaft and the turning plate are not on the same plane, and the shaft is positioned on the cylinder body on the upper side of the leak hole.

Preferably, soft glue is arranged at the edge of the turning plate.

Preferably, soft glue is arranged at the edge of the leak hole.

Preferably, the turning plate is planar and forms a certain included angle with the barrel.

Furthermore, the turning plate is non-planar and forms a certain included angle with the cylinder body.

Preferably, the force application mechanism is a link mechanism, and the counterweight block applies force to the turnover plate through a link rod.

Furthermore, the force application mechanism is a balancing weight fixed on the turning plate.

Furthermore, the force application mechanism is elastic force acting on the shaft or the turning plate.

The invention has the beneficial effects that: 1. when the device is opened, the upper end of the turning plate is turned to the outer side of the barrel, a drainage and pollution discharge area is avoided, sundries are prevented from being hooked, and the sealing is not easy to lose efficacy; 2. the application range is wider, the shape can be flexibly produced according to the application environment, and the installation can be flexibly carried out according to the trend of drainage and pollution discharge facilities; 3. the position of the obvious bulge is not arranged in the leakage hole, and the maintenance is convenient.
