Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention will be further described:

[0011] A one-way valve, comprising an inlet inner tube 4, a threaded sleeve 3, a valve membrane 2, and an outlet inner tube 1, the inlet inner tube 4 is sleeved on the inlet side of the valve membrane 2, and the threaded sleeve 3 is sleeved on the inlet inner tube 4 Connecting end, the outlet inner tube 1 is sleeved on the outlet side of the valve membrane 3, the outlet inner tube 1 is connected with the threaded sleeve 3, and withstands the valve membrane 2. Both ends of the inlet inner pipe 4 are provided with external threads, and the connection between the inlet inner pipe 4 and the valve membrane 2 is provided with a sealing protrusion, which can be well connected with the threaded sleeve and form a good seal with the valve membrane to prevent leakage.

[0012] The thickness of the connecting ring around the valve membrane 2 is relatively large, and sealing grooves ar...

Abstract

The invention relates to a one-way valve. The one-way valve is characterized by comprising an inlet inner tube, a threaded sleeve, a valve membrane and an outlet inner tube; the inlet inner tube is connected to the inlet side of the valve membrane in a sleeved manner, the threaded sleeve is connected to the connecting end of the inlet inner tube in a sleeving manner, the outlet inner tube is connected to the outlet side of the valve membrane in a sleeved manner, and the outlet inner tube is connected with the threaded sleeve and ejects the valve membrane; and outer threads are arranged at the two ends of the inlet inner tube, sealing protrusions are arranged at the portions where the inlet inner tubes are connected with the valve membrane, the thickness of a connecting ring in the periphery of the valve membrane is large, and sealing grooves are formed in the two sides of the connecting ring. According to the one-way valve, one-way flowing of fluid is achieved in the manner that a heavy membrane flap of a valve body moves, and the one-way valve has the beneficial effects of being reliable in connection, simple in structure, good in maintainability, long in service life and the like.

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. When the pressure at one end of the pipeline is high, the ball at the cone hole will be pushed away. Make the valve body open, when the reverse pressure is large, the ball will seal the taper 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 described above is characterized in that it includes an inlet inner tube, a threaded sleeve, a valve membrane, and ...
