Abstract
The invention discloses a flexible check valve with a single circle of engaged silicone rubber. The flexible check valve is used in a drainage system and comprises a duckbill, a valve body and a flange. A circle of surface-engaged silicone rubber layer is arranged on the inner sides of two opposite edges of the duckbill. Due to the fact that silicone rubber has viscidity when encountering water, the flexible check valve can better prevent water backflow.
Description
Technical field
The present invention relates to water delivery water bailing component field, particularly relate to a kind of flexible check valve with silica gel edge sealing.
Background technology
Check valve is the one in water delivery water bailing component, it is generally divided into metal check valve and flexible check valve, and use service life of the flexible check valve that rubber makees main material longer than metal check valve, in actual use, owing to the closure using the rubber flexible check valve of making material of main part is the best, affect its non-return effect.
Summary of the invention
For prior art and the problems referred to above of equipment, the present invention makes following design: structure includes flange, valve body, duckbilled, it is characterized in that: the inner side of described duckbilled, it is fixed with a circle layer of silica gel, the surface of described layer of silica gel is dentation, inside described duckbilled, the faying face with described layer of silica gel has groove, and described layer of silica gel simultaneously has corresponding bulge-structure inside duckbilled.
The present invention utilizes silica gel chance water to have certain viscosity, more than inside can be in external pressure, anti-backflow of fitting closely, concaveconvex structure inside layer of silica gel and described duckbilled expands both faying face and active forces simultaneously, bond strength after making it bonding is more preferable, designs ingenious, is worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Embodiment one
As shown in Figure 1, the present invention includes flange 1, valve body 2, duckbilled 3, it is characterized in that: the inner side of described duckbilled 3, it is fixed with a circle layer of silica gel 4, the surface of described layer of silica gel 4 is dentation, the layer of silica gel on duckbilled both sides is ratcheting after merging, and inside described duckbilled 3, the faying face with described layer of silica gel 4 has groove, and described layer of silica gel 4 simultaneously has corresponding bulge-structure inside duckbilled 3.
These are only preferred embodiment of the present invention, therefore the scope of present invention enforcement can not be limited according to this that the equivalence change i.e. made according to description of the invention content and decoration all should belong in the range of present invention covering.
