Inclined flap check valve

Abstract

The invention discloses an inclined flap check valve, which includes a valve body, a valve seat, and a valve clack. A medium channel is formed in the valve body, the valve clack is arranged in the medium channel in an inclining mode and in sealing fit with the axial end surface of the valve seat, one end of the valve clack is pivoted with the valve body, and the valve clack rotates around a pivoting shaft to realized on and off of the medium channel; and the medium channel is a straight-through channel, the valve clack is a non-balance weight valve clack, and the thickness, away from one sideof the pivoting shaft, on the valve clack is larger than the thickness, near one side of the pivoting shaft, on the valve clack. Through arranging the medium channel as the straight-through channel, amedium gradually moves in the horizontal direction, and then resistance of the medium in the medium channel is lowered, so that pressure loss in the medium flowing process is lowered; and next, the thickness, away from the pivoting shaft, on the valve clack larger than the thickness, near the pivoting shaft, on the valve clack is arranged, balance weight arranged on the valve chalk is avoided, and thus the valve chalk can be used in a small-diameter and high-class valve.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an oblique flap check valve. Background technique [0002] Check valve, also known as one-way valve or check valve or one-way valve, refers to a valve whose opening and closing parts are circular discs and rely on its own weight and medium pressure to generate actions to block the backflow of the medium. The medium in the pipeline flows back. Among them, the moment of inertia and moment of inertia of the disc movement of the swing check valve in the prior art are relatively large, and the impact on the sealing surface of the valve at the moment of closing the valve is relatively large, which is unfavorable to the safety of the system; When it is sensitive, sparks caused by strong impacts will have serious consequences. The inclined disc check valve can solve the problems of slow opening of the swing check valve, large reseating force when the valve disc falls back, and high-pres...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the pressure loss of the medium in the prior art when the inclined disc check valve flows, and because the inclined disc check valve with a counterweight is not suitable for small The defects in the working condition of the valve with high caliber, so as to provide a kind of oblique disc check valve
