Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention will be further described:

[0012] A one-way valve, comprising a valve body 1 and a valve core 2 installed in the valve body, the bottom surface of the valve core is provided with a supporting spring 3, the inner wall surface of the inlet of the valve body is provided with a first elastic member 4, the first A baffle plate 5 is provided on the inner wall of the valve on the opposite side of the elastic member to the inlet. Since the elastic piece is also designed on the top surface of the valve core, the upward pulling force of the valve core is increased, which solves the problem of medium backflow caused by poor sealing and valve core jamming during the locking process of the check valve.

[0013] A supporting rod 6 is arranged at the joint between the above-mentioned first elastic member and the inner wall surface, and the top end of the supporting rod is in the small hole 7 on the inner wall surf...

Abstract

The invention relates to a check valve. The check valve comprises a valve body and a valve element installed in the valve body, wherein a supporting spring is arranged on the bottom face of the valve element. The check valve is characterized in that first elastic parts are arranged on the inner wall face of an inlet of the valve body, and baffles are arranged on the portion, where the first elastic parts are opposite to the inlet, of the inner wall face of the valve body. According to the check valve, because the first elastic parts are arranged on the inner wall face of the inlet of the valve body, and the baffles are arranged on the portion, where the first elastic parts are opposite to the inlet, of the inner wall face of the valve body, the upward tension of the valve element is increased, and the problem that the check valve cannot be sealed tightly in the locking process is solved.

Description

technical field [0001] The invention relates to a one-way valve. Background technique [0002] One-way valves are used in pipeline containers to limit pressure or flow direction. A general one-way valve is composed of a pipeline, a sealing ball, a spring and a cone-shaped structure. The valve body conducts, and when the reverse pressure is large, the ball seals the tapered hole, prohibiting the passage of fluid, and completing one-way conduction. Ordinary one-way valves have complex structures, and there are problems such as wear, leakage and spring failure. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to provide a technical solution for a one-way valve. [0004] The one-way valve includes a valve body and a valve core installed in the valve body, the bottom surface of the valve core is provided with a supporting spring, and it is characterized in that a first elastic member is provided on the...
