Abstract

The invention discloses a check valve. The check valve comprises an inlet inner tube, a threaded sleeve, a valve diaphragm and an outlet inner tube. The inlet inner tube is sleeved on one side of a valve diaphragm inlet, the threaded sleeve is sleeved at a connection end of the inlet inner tube, the outlet inner tube is sleeved on the valve diaphragm outlet side, and the inlet inner tube is connected with the threaded sleeve and abuts against the valve diaphragm. By the aid of the mode, the check valve has the advantages of being reliable in connection, simple in structure, good in maintenance, long in service life and the like.

Description

technical field [0001] The invention relates to the field of one-way valves, in particular to a flap type 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] The technical problem mainly solved by the present invention is to provide a one-way valve, which realizes the one-way flow of fluid through the movement of the valve body flap, and has the advantages of reliable connection, simp...
