Abstract
The utility model discloses a many rings of flexible check valves of meshing silica gel for drainage system, it includes duckbilled, valve body, flange, there is the silica gel layer of the surperficial meshing of a plurality of circles two opposite side inboards of duckbilled department, are equipped with viscidity because the glassware for drinking water is met to silica gel for its can be better the backward flow that prevents water.
Description
Technical field
The utility model is related to water delivery water bailing component field, more particularly, to a kind of flexible check valve with silica gel edge sealing.
Background technology
Check valve is one of water delivery water bailing component, is generally divided into metal check valve and flexible check valve, and uses rubber
The service life that the flexible check valve of main material made by glue is longer than metal check valve, in actual use, due to adopting
The closed that rubber makees the flexible check valve of material of main part is not very good, affects its non-return effect.
Content of the invention
For the problems referred to above of prior art and equipment, the utility model makes following design:Structure includes flange, valve
Body, duckbilled it is characterised in that:The inner side of described duckbilled, is fixed with some circle layer of silica gel, the surface of described layer of silica gel is in dentation,
There is groove with the faying face of described layer of silica gel, described layer of silica gel simultaneously has corresponding projection towards inside duckbilled inside described duckbilled
Structure.
The utility model is met water using silica gel and is had certain viscosity, can be closely to paste more than inside in external pressure
Close anti-backflow, simultaneously the concaveconvex structure inside layer of silica gel and described duckbilled expand both faying face and active force so as to
More preferably, design is ingenious, is worthy to be popularized for bond strength after bonding.
Brief description
Fig. 1 is the utility model structural representation.
Specific embodiment
Embodiment one
As shown in figure 1, the utility model include flange 1, valve body 2, duckbilled 3 it is characterised in that:The inner side of described duckbilled 3,
It is fixed with two circle layer of silica gel 4, the surface of described layer of silica gel 4 is in dentation, ratcheting, described duckbilled after the layer of silica gel merging on duckbilled both sides
There is groove 3 inner sides with the faying face of described layer of silica gel 4, and described layer of silica gel 4 has raised knot accordingly towards duckbilled 3 inner side one side
Structure.
These are only the utility model preferred embodiment, therefore the scope of the utility model enforcement can not be limited according to this, that is,
The equivalence changes made according to the utility model description and decoration, all should belong in the range of the utility model covering.
