Description

Formula inlet non return check valve in pipe

Technical field

The utility model is related to a kind of non-return valve, and espespecially one kind is installed in hollow tube, possesses one-way check effect Formula inlet non return check valve in pipe.

Background technology

It is existing it is many provide fluid circulation body, be in response to one-way flow is only capable of the need for, can all be configured between pipeline There is non-return valve, medical air bed is to avoid air return in air bed from being one.Traditional method, presss from both sides after can pipeline be cut off An exposed non-return valve is equipped with, just completes to fix with the pipeline at the band folder beam non-return valve two ends.Existing structure is not only beautiful See, time-consuming to take a lot of work, particularly prolonged use posterior cord will cause gas leakage or separate failure and necessary with fracture or the possibility for releasing Maintenance, it is not satisfactory.

It is clear that existing body check valve arrangement, still undesirable perfect, there is improved necessity in fact.Inventor has mirror In this, spy creates into the utility model to grind, and the phase can borrow proposition of the present utility model, and to improve the shortcoming of prior art, the phase makes pipe The function of body non-return valve is able to more improve and preferable, meets actual demand.

Utility model content

To improve the shortcomings that foregoing existing exposed body non-return valve has, the utility model provides formula list in pipe To non-return valve, its main purpose is to provide a kind of body inlet non return check valve, and it uses and concealed is designed at tubular body, dress As long as body one end is filled in timing, inside be can be used, and pipe need to be cut in conjunction with band without as prior art, be can reach attractive in appearance, easy The purpose such as assembling and reduction likelihood of failure.

To reach above-mentioned purpose, the specific technological means of the utility model is：The inlet non return check valve is by a body and a film Body is constituted；Wherein, the body is in a hollow tubular in a hollow tubular or probably, and it is internal with a space, the interior volume A catch is provided with, the catch center offers a perforation, and the opening of hollow out is offered around the perforation on the catch；In addition, The body exterior is equipped with one or more bulge loop, and the two sides of the bulge loop are respectively a relatively low oblique oblique surface With a relatively precipitous oblique retaining surface.The film body is made up of a lamellar body with an axis body, wherein, the area of the lamellar body is equal to or general Equal to the area of the catch of the body interior, the axis body is outer extended by the mediad of the one side of the lamellar body, and is set on the axis body It is equipped with a baffle ring.The axis body and baffle ring borrow baffle ring block after passing the perforation of the body, form the link of film body and body Relation.

Wherein, the inlet non return check valve can be used to be placed through a tubular body.

The utility model have the advantages that it is attractive in appearance, be easily assembled and reduce likelihood of failure.

Specific embodiment

The now careful just structure composition of formula inlet non return check valve in pipe of the present utility model and the effect that can be generated, cooperation are attached Figure, lifts a preferred embodiment detailed description of the present utility model as follows：

Head is referred to shown in Fig. 1 and Fig. 2, and formula inlet non return check valve is by 2 groups of a body 1 and a film body in pipe of the present utility model Into.

Wherein, the body 1 is in a hollow tubular in a hollow tubular or probably, and it is internal with a space 11, the space 11 are internally provided with a catch 12, and the center of catch 12 offers a perforation 121, is opened up around the perforation 121 on the catch 12 There is the opening 122 of hollow out；In addition, being equipped with one or more bulge loop 13 outside the body 1, the two of the bulge loop 13 are constituted Side is respectively the relatively precipitous oblique retaining surface 132 of a relatively low oblique oblique surface 131 and.The film body 2 is by a lamellar body 21 Constituted with an axis body 22, wherein, the area of the lamellar body 21 is equal to or is approximately equal to the area of the catch 12 of the body 1 inside, this Axis body 22 is outer extended by the mediad of the one side of the lamellar body 21, and a baffle ring 221 is provided with the axis body 22.The axis body 22 with After the baffle ring 221 can pass the perforation 121 of the body 1, it is difficult to deviate from again by means of the block of baffle ring 221, forms film body 2 and body 1 Connection relationship.

Such as Fig. 3, the inlet non return check valve can be used to be placed through the inside of a body 3, consequently, it is possible to the fluid energy in body 3 With one-way flow, another relative effect to check.

In the utility model, why the bulge loop 13 is provided with relatively low oblique oblique surface 131, is to be easier to plug Enter in the body 3, as set the relatively precipitous oblique retaining surface 132, then be in order to improve it is another to prevention power, with reduce The possibility that the inlet non return check valve is moved in body 3 by reverse pressure.

Please coordinate Fig. 1 and Fig. 4, when the utility model is implemented, when fluid produces forward pressure in body 3, fluid energy The deformation of lamellar body 21 is smoothly promoted, fluid, by body 3, completes normal flowing using the periphery of lamellar body 21.

Please coordinate Fig. 1 and Fig. 5, when fluid produces reverse pressure in body 3, fluid touches the lamellar body 21, and will The lamellar body 21 is tightly suppressed at catch 12, and the lamellar body 21 can be used to close each opening 122, cause the inlet non return check valve to be formed The effect of check.

In sum, the utility model provides formula inlet non return check valve in pipe, and it is special that its technology contents complies fully with utility model The acquirement key element of profit.The utility model is industrially utilized really, is used in not seen publication before application or disclosing, and It is not technology that public domain is known.Also, the utility model can effectively solve long-standing problem in the prior art and reach The demand of associated user and long term consumer, it was demonstrated that the utility model can not be readily accomplished.The utility model has patent Key elements such as " practicality ", " novelty " and " creativeness " of law regulation, spy proposes patent application in accordance with the law.

Though the utility model is described by previous embodiment, but still its form of alterable and details, do not depart from this practicality New spirit and reach, and be can be appreciated that by those skilled in the art.Foregoing preferred embodiment of the present utility model, only by means of this One of mode that utility model principle can be embodied, but system is not limited thereto, should be according to foregoing claims institute circle It is set to standard.
