Abstract
The utility model discloses a one-way valve, which is characterized in that: the one-way valve comprises a rubber valve body; the rubber valve body is provided with a vertically penetrated passageway; the passageway is provided with an opening end and a closing end; and the closing end can be opened elastically. The one-way valve has a simple structure, fewer accessories, convenience and durability in installation, long service life and good sealing effect.
Description
Technical field
The utility model relates to a kind of improvement invention of one-way valve.
Background technique
As everybody knows, one-way valve is because the applicable situation difference has a variety of specifications and pattern.But one-way valve generally all has the spool of valve body and unidirectional unlatching, so that structure generally all seems is comparatively complicated, accessory is many, installs to be inconvenient to not be durable, working life is short, and sealing effect is poor.
Summary of the invention
In view of the problem of known technology existence at present, the technical problem that the utility model will solve is to be to provide a kind of simple in structure, and accessory is few, and is easy for installation durable, long service life, the one-way valve of good sealing effect.
For solving the problems of the technologies described above, the utility model takes following technological scheme to accomplish:
A kind of one-way valve is characterized in that: said one-way valve comprises rubber valve body, and rubber valve body has the passage that runs through up and down, and passage has opening flared end and closure of openings end, but closure of openings end elasticity is opened.
The one-way valve of said structure; The spool that does not have unidirectional unlatching; Its unidirectional open function is to open through the elasticity of the closure of openings end of rubber valve body to realize; When the hydrodynamic pressure that gets into from the opening flared end of rubber valve body during greater than the elasticity tension of closure of openings end, the closure of openings end of rubber valve body will be opened, and the hydrodynamic pressure of other direction all can not make the closure of openings end of rubber valve body open.The said structure one-way valve, simple in structure, accessory is few, and is easy for installation durable, long service life, good sealing effect.
Stablize for ease of the installation of rubber valve body and the openings of sizes of maintenance opening flared end, said one-way valve also includes base, and base is provided with in the opening flared end of rubber valve body passage.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the utility model.
Embodiment
Accompanying drawing has been represented the technological scheme and the embodiment of the utility model, combines accompanying drawing to further describe each relevant details and working principle thereof of embodiment below again.
With reference to accompanying drawing 1, this kind one-way valve comprises rubber valve body 4 and plastics base 1; Rubber valve body 4 has the passage 5 that runs through up and down, and the upper shed of passage 5 is the opening flared end, and the under shed 6 of passage is the closure of openings end; But closure of openings end 6 elasticity are opened; Said plastics base 1 is provided with in the opening flared end of rubber valve body passage 5, and the lower end surface of plastics base 1 is a tube-in-tube structure 3, and the cylindrical of tube-in-tube structure 3 is set in the passage 5 of rubber valve body; Keep the openings of sizes of the opening flared end of rubber valve body to stablize, the endoporus 2 of tube-in-tube structure 3 communicates with the passage 5 of rubber valve body.
When the hydrodynamic pressure that gets into from the opening flared end of rubber valve body during greater than the elasticity tension of closure of openings end; The closure of openings end of rubber valve body will be opened; And the hydrodynamic pressure of other direction all can not make the closure of openings end of rubber valve body open, thereby realizes the unidirectional open function of one-way valve.The one-way valve of said structure, simple in structure, accessory is few, and is easy for installation durable, long service life, good sealing effect.
Claims (2)
