Abstract

The utility model relates to a check valve. The check valve comprises a conical shield (2) with a first connection pipe (1) and a substrate (8) with a second connection pipe (9); central lines of the first connection pipe (1) and the second connection pipe (9) are collinear; an annular skirt edge (3) is arranged at the bottom of the conical shield (2); an annular edge (7) matched with the skirt edge (3) is arranged at the top of the substrate (8); the edge (7) is inserted into the skirt edge (3) and is connected by adhesion; multiple base plates (4) spaced at equal angles are arranged along the peripheral direction of the inner wall of the conical shield (2); the bottom edges of the base plates (4) are arc. A seal pad (6) made of a soft material is arranged between the base plates and the substrate (8).

Description

A kind of one-way valve
Technical field
The utility model relates to a kind of one-way valve.
Background technique
On the gas circuit of industry equipment, oil circuit, water route pipeline, according to actual needs, one-way valve is often set, only flow and can not reflux along a direction for control media.Existing one-way valve general structure complexity, is not very high occasion for some simple pipelines and precision requirement, and above-mentioned one-way valve has promoted the cost of enterprise operation.
Model utility content
The utility model provides a kind of one-way valve simple in structure, easy to use for solving the technical problem existing in known technology.
The utility model for the technological scheme that solves the technical problem that exists in known technology and take is: a kind of one-way valve comprises with the cone-shaped hood of the first connecting tube with the pedestal of the second connecting tube, the centerline collineation of described the first connecting tube and the second connecting tube; Be provided with annular skirt in the bottom of cone-shaped hood, be provided with the annular edge coordinating with skirt at the top of pedestal, edge inserts in skirt and bonding connection; On the inwall of cone-shaped hood, be provided with the backing plate at circumferential equal angles interval, multiple edges, the bottom margin of described backing plate is arc, is provided with the sealing gasket of soft materials between backing plate and pedestal.
Advantage of the present utility model and good effect are: owing to having adopted above-mentioned design, the utility model is simple in structure, cost is lower.After in access pipeline, by floating of sealing gasket, control media can only flow to the first connecting tube by the second connecting tube, in the time that medium has the trend of reverse flow, sealing gasket is fitted in completely by deformation on the port of the second connecting tube and realizes and damming, easy to use and non-return is reliable for effect.
Brief description of the drawings
Fig. 1 is cross section structure schematic diagram of the present utility model.
In figure: 1, the first connecting tube; 2, cone-shaped hood; 3, skirt; 4, backing plate; 5, diapire; 6, sealing gasket; 7, edge; 8, pedestal; 9, the second connecting tube.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the utility model comprises with the cone-shaped hood 2 of the first connecting tube 1 with pedestal 8, the first connecting tubes 1 of the second connecting tube 9 and both centerline collineations of the second connecting tube 9.Actually add man-hour, the first connecting tube 1 and cone-shaped hood 2 be one-body molded to be obtained, the second connecting tube 9 obtains with pedestal 8 is one-body molded, and above-mentioned integral forming process comprises molding and forming etc.
Be provided with annular skirt 3 in the bottom of cone-shaped hood 2, be provided with the annular edge 7 coordinating with skirt 3 at the top of pedestal 8, edge 7 inserts in skirt 3 and bonding connection, realizes both installations of cone-shaped hood 2 and pedestal 8.
On the inwall of cone-shaped hood 2, be provided with the backing plate 4 at circumferential equal angles interval, multiple edges, the bottom margin of backing plate 4 is arc, is provided with soft materials as the sealing gasket 6 of plastic material, quality of rubber materials between backing plate 4 and pedestal 8.
The diapire 5 of pedestal 8, the surface of contact of sealing gasket 6 and pedestal 8, should be machined to higher planeness, as far as possible to strengthen the tightness between sealing gasket 6 and diapire 5.
Working method: by this one-way valve access pipeline, medium can only carry out by the flowing of the second connecting tube 9 to first connecting tube 1 directions, and now sealing gasket 6 is wrapped on each backing plate 4, and medium is via the edge circulation of sealing gasket 6.In the time that medium has the trend of reverse flow, sealing gasket 6 is fitted in completely by deformation on the diapire 5 of pedestal 8, on the port of the second connecting tube 9, realizes and damming.
