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
The present invention relates to the one-way valve field, particularly relate to a kind of membrane flap type 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 comprised of pipeline, ball sealer, spring and cone structure, when large, back down the spheroid at taper hole place when pipeline one end pressure, make the valve body conducting, when reverse pressure is large, make ball that taper hole is sealed, forbid that fluid passes through, and completes one-way conduction., there are the problems such as wear and leakage and spring failure in common one-way valve structures complexity.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of one-way valve, weighs the mode of film lobe motion by valve body, realizes the one-way flow of fluid, have connect reliable, simple in structure, maintainability is good, the advantages such as long service life.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of one-way valve is provided, comprise: entrance inner tube, screw shell, valve film, outlet inner tube, the entrance inner tube is socketed in valve film inlet side, screw shell is socketed in entrance inner tube connecting end, the outlet inner tube is socketed in valve film outlet side, and the outlet inner tube is connected with screw shell, and withstands the valve film.
In a preferred embodiment of the present invention, entrance inner tube two ends are provided with outside thread, and entrance inner tube and valve film joint are provided with seal convexity.
In a preferred embodiment of the present invention, around described valve film, connecting ring thickness is larger, and seal groove is offered in both sides.
In a preferred embodiment of the present invention, described valve film is the rubber manufacture, and the valve film contains 3 film lobes, is mutually 120 ° of angles.
In a preferred embodiment of the present invention, described screw shell is provided with internal thread, also offers tool withdrawal groove on the symmetry plane perpendicular to central axis.
In a preferred embodiment of the present invention, described outlet inner tube two ends are provided with outside thread, and outlet inner tube and valve film joint are provided with seal convexity.
The invention has the beneficial effects as follows: one-way valve of the present invention weighs the mode of film lobe motion by valve body, realizes the one-way flow of fluid, have connect reliable, simple in structure, maintainability is good, the advantages such as long service life.
The accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of one-way valve one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, outlet conduit, 2, the film lobe, 3, screw shell, 4, inlet pipe.
Embodiment
Below will the technological scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of one-way valve, comprise: entrance inner tube 4, screw shell 3, valve film 2, outlet inner tube 1, entrance inner tube 4 is socketed in valve film 2 inlet sides, screw shell 3 is socketed in entrance inner tube 4 connecting ends, outlet inner tube 1 is socketed in valve film 3 outlet sides, outlet inner tube 1 is connected with screw shell 3, and withstands valve film 2.
Entrance inner tube 4 two ends are provided with outside thread, and entrance inner tube 4 is provided with seal convexity with valve film 2 joints, can well be connected with threaded sleeve and form excellent sealing, Leakage prevention with the valve film.
Around described valve film 2, connecting ring thickness is larger, and seal groove is offered in both sides, with connecting tube, forms excellent sealing, Leakage prevention.
Described valve film 2 is the rubber manufacture, and valve film 2 contains 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, also offers tool withdrawal groove on the symmetry plane perpendicular to central axis, with valve film connecting ring, effectively coordinates and forms sealing.
Described outlet inner tube 1 two ends are provided with outside thread, and outlet inner tube and valve film joint are provided with seal convexity, well are connected with threaded sleeve and form excellent sealing, Leakage prevention with the valve film.
The one-way valve working procedure is:
When inlet side pressure is large, pressure makes the film lobe scatter to surrounding, and fluid is passed through, and when outlet side pressure is large, pressure-acting, in the film lobe, makes the Mo Banxiang center gather, and sealing, prevent reverse flow mutually.
The beneficial effect of one-way valve of the present invention is:
One, complete the usage requirement of one-way valve by the action of film lobe, simple in structure;
Two, by the valve film, be the rubber manufacture, long service life, anti-corrosion effects is good;
Three, with common one-way valve, compare there is compact structure, reliability is high, the advantages such as long service life.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present invention.
