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
The present invention relates to a kind of one-way valve.
Background technique
One-way valve is used in pipe container, for limiting pressure or the flow direction, general one-way valve is made up of pipeline, ball sealer, spring and cone structure, when pipeline one end pressure is large, backs down the spheroid at taper hole place, make valve body conducting, when reverse pressure is large, taper hole is sealed by ball, forbids that fluid passes through, complete one-way conduction.Common one-way valve structures is complicated, there is the problem such as wear and leakage and spring failure.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technological scheme of one-way valve.
Described a kind of one-way valve, it is characterized in that comprising pipe in pipe in entrance, screw shell, valve film, outlet, in entrance, pipe box is connected on valve film inlet side, screw shell is socketed in pipe connecting end in entrance, in outlet, pipe box is connected on valve film outlet side, in outlet, pipe is connected with screw shell, and withstands valve film; In described entrance, pipe two ends are provided with outside thread, and in entrance, pipe and valve film joint are provided with seal convexity, and around described valve film, connecting ring thickness is comparatively large, and seal groove is offered in both sides.
Described one-way valve, it is characterized in that described valve film is rubber, valve film contains 3 film lobes, is mutually 120 ° of angles.
Described one-way valve, is characterized in that described screw shell is provided with internal thread, is also offering tool withdrawal groove perpendicular on the symmetry plane of central axis.
Described one-way valve, is characterized in that in described outlet, pipe two ends are provided with outside thread, and in outlet, pipe and valve film joint are provided with seal convexity.
One-way valve of the present invention, by the mode of the heavy film lobe motion of valve body, realizes the one-way flow of fluid, have connect reliable, structure is simple, maintainability good, the advantages such as long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
A kind of one-way valve, comprise pipe 1 in pipe 4 in entrance, screw shell 3, valve film 2, outlet, in entrance, pipe 4 is socketed in valve film 2 inlet side, screw shell 3 is socketed in pipe 4 connecting end in entrance, in outlet, pipe 1 is socketed in valve film 3 outlet side, in outlet, pipe 1 is connected with screw shell 3, and withstands valve film 2.In entrance, pipe 4 two ends are provided with outside thread, and in entrance, pipe 4 and valve film 2 joint are provided with seal convexity, can well be connected with threaded sleeve and form excellent sealing with valve film, Leakage prevention.
Described valve film 2 surrounding connecting ring thickness is comparatively large, and seal groove is offered in both sides, forms excellent sealing, Leakage prevention with connecting tube.Described valve film 2 is rubber manufacture, and valve film 2, containing 3 film lobes, is mutually 120 ° of angles, has good anti-corrosion capacity and good working life.Described screw shell 3 is provided with internal thread, is also offering tool withdrawal groove perpendicular on the symmetry plane of central axis, effectively coordinates to be formed to seal with valve film connecting ring.In described outlet, pipe 1 two ends are provided with outside thread, and in outlet, pipe and valve film joint are provided with seal convexity, be well connected and form excellent sealing with valve film, Leakage prevention with threaded sleeve.
Non-return valve operational process is: when inlet-side pressure is large, and pressure makes film lobe scatter to surrounding, and fluid is passed through, and when outlet side pressure is large, pressure acts on film lobe, Mo Banxiang center is gathered, mutually seals, prevent reverse flow.
The beneficial effect of one-way valve of the present invention is:
One, completed the usage requirement of one-way valve by the action of film lobe, structure is simple;
Two, be rubber manufacture by valve film, long service life, anti-corrosion effects is good;
Three, compared with common one-way valve, there is compact structure, reliability is high, the advantages such as long service life.
