Abstract
The utility model discloses a check valve for a windshield water pipe of an automobile. The check valve comprises a three-way pipe body, wherein the three-way pipe body is in a Y-shaped, and the three-way pipe body is internally provided with a check device. In the check valve, as the three-way pipe body is internally provided with the check device, materials are saved, and the assembly technology is simplified; secondly, one check device controls two nozzles, so that the flow and spray time of one nozzle are equal to those of the other nozzle, and the cleaning effects on the windshield of the automobile are the same.
Description
Technical field
The utility model relates to a kind of safety check, relates in particular to a kind of automobile air window water pipe safety check.
Background technique
The working principle of safety check is that water intake is exerted pressure by washer pump, when pressure reaches specified value (pressure greater than the spring initial pressure time), liquid backs down sealing gasket and arrives two water outlets by runner, be transported to nozzle by pipeline more afterwards, at last, liquid cleans automobile air window; When washer pump is closed, pressure disappears, and sealing gasket is because runner is pushed down in the effect of the power of spring, thereby liquid can not be passed through, at this moment according to the principle liquid return of gravity.But because sealing gasket is closed in the safety check, liquid can not be back to terminal, remains in the pipeline always.After washing system started again, because liquid is full of whole pipeline all the time, the liquid ejection time was reduced in 1 second, can clean automobile air window rapidly like this, can avoid windshield wiper dried glass of scraping when not having water simultaneously.
But, current check device is mounted in external of three-way pipe, because each car uses two nozzles, need work simultaneously, a safety check promptly is installed respectively below two nozzles, each car needs two safety check and a threeway body, and like this just relatively waste material and assembly technology are also more loaded down with trivial details; Secondly, when work, though the washer pump cracking pressure is identical, but two nozzles are respectively by two check device controls, therefore, the flow and the discharge time of the ejection of each nozzle are inconsistent, finally the result that automobile air window is cleaned also inconsistent (Yi Bian promptly occur easily cleaning up, Yi Bian cleaning is unclean; Clean on one side and finish, on one side clean intact).
Summary of the invention
The utility model provides a kind of automobile air window water pipe safety check at deficiency of the prior art, this automobile air window water pipe safety check economical with materials, and it is consistent with discharge time to control the flow of two nozzles ejection.In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of automobile air window water pipe safety check comprises the threeway body, and described threeway body is " Y " type, and described threeway body inside is provided with check device.
In the technique scheme, described check device comprises sealing gasket, and described sealing gasket covers on the boss of threeway body intersection, and described sealing gasket is provided with elastic device, and described elastic device is provided with check-valve cap, and described check-valve cap be located on the threeway body.
In the technique scheme, described elastic device is a spring.
In the technique scheme, offer vent on the described check-valve cap.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
Therefore the utility model has been saved material and has been simplified assembly technology owing to be provided with check device in threeway body inside; Secondly, by two nozzles of a check device control, so the flow of each nozzle is consistent with discharge time, thereby the result that automobile air window is cleaned is also consistent.
Description of drawings
Fig. 1 is the perspective view of automobile air window water pipe with safety check.
Fig. 2 is the plane structure schematic representation of automobile air window water pipe with safety check.
Fig. 3 is the cross-sectional view of automobile air window water pipe with safety check.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Referring to Fig. 1～3, a kind of automobile air window water pipe safety check comprises threeway body 1, described three-way pipe
Body 1 is " Y " type; the bottom that threeway body 1 is " Y " type structure is an intake pipe; two on top is an outlet pipe; be not to limit protection domain of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
Described threeway body 1 uses polyoxymethylenes resin (being plastics POM material), be commonly called as plastic steel, this mechanical property of materials is good, shock-resistant, threeway body 1 inside is provided with check device 2, described check device 2 comprises sealing gasket 2b, sealing gasket 2b adopts ethylene propylene diene rubber to make (being rubber EPDM material), described sealing gasket 2b covers on the boss 5 of threeway body 1 intersection, described sealing gasket 2b is provided with elastic device 3, preferably, elastic device 3 is springs that stainless steel material is made, described elastic device 3 is provided with check-valve cap 4, and described check-valve cap 4 be located on the threeway body 1, and is preferred, offer vent 6 on the check-valve cap 4, the benefit of doing like this is to be convenient to the smooth unlatching of automobile air window water pipe with safety check.
The water inlet pipe end of the utility model automobile air window water pipe with safety check is installed on the washing system kettle body, when its work, start washer pump, when pressure reaches specified value (pressure greater than the spring initial pressure time), liquid backs down the sealing gasket 2b that covers on the boss 5 and arrives two outlet pipes by runner, be transported to nozzle by pipeline more afterwards, last, liquid cleans automobile air window; When washer pump is closed, pressure disappears, and sealing gasket 2b is because runner is pushed down in the effect of the power of spring 3, thereby liquid can not be passed through, at this moment according to the principle liquid return of gravity.But because sealing gasket 2b is closed in the safety check.Liquid can not be back to terminal, remains in the pipeline always.After washing system started again, because liquid is full of whole pipeline all the time, the liquid ejection water time was reduced in the 1S.Can clean automobile air window rapidly like this, can avoid windscreen wiper dried glass of scraping when not having water simultaneously.
In sum, therefore the utility model has been saved material and has been simplified assembly technology owing to be provided with check device in threeway body inside; Secondly, by two nozzles of a check device control, so the flow of each nozzle is consistent with discharge time, thereby the result that automobile air window is cleaned is also consistent.
