Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched
The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
In the disclosure, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower " is the list with the disclosure
Upper and lower in the state of when being installed to body side wall bottom to valve, " inside and outside " refers to the inner and outer of corresponding component profile.
Present disclose provides a kind of check valves, as shown in Figure 1 to Figure 3, including valve body 1 and the bullet being arranged in the valve body 1
Property valve block 2, fluid inlet 3 and fluid outlet 4 are formed on valve body 1, elastic valve plate 2 is arranged in fluid inlet 3 and fluid outlet 4
Between.Sealing is formed under normal condition, between elastic valve plate 2 and valve body 1 or only there are micro gap, closed check valves；Work as stream
When the pressure difference of body entrance 3 and fluid outlet 4 reaches certain value, under the action of the pressure difference, flexible deformation occurs for elastic valve plate 2,
So that forming biggish gap between elastic valve plate 2 and valve body, fluid inlet 3 is connected to fluid outlet 4, and check valve is opened.Tool
Body could be formed with position limiting structure in the present embodiment on the inner wall of valve body 1, when closed check valve, elastic valve plate 2 supported
It is connected to the position limiting structure.Side where the position limiting structure limits elastic valve plate 2 towards fluid inlet 3 deforms, that is to say, that should
Side where position limiting structure only allows elastic valve plate 2 towards fluid outlet 4 deforms.
The check valve of the disclosure can be applied to various suitable occasions.Typically, check valve provided by the disclosure can
To be installed in body side wall bottom to use as drain valve.When check valve is installed in side wall bottom, 3 court of fluid inlet
To fluid outlet 4 is downward.When the intracavitary ponding of side wall type is excessive, by the gravity (that is, effect of hydraulic pressure) of water, so that
Side where elastic valve plate 2 towards fluid outlet 4 deforms, so that fluid inlet 3 be made to be connected to fluid outlet 4, check valve is beaten
It opens, and then the intracavitary ponding of type is discharged；When cut-offfing, interior air pressure increases, by the effect of vehicle internal and external pressure difference, so that
Side where elastic valve plate 2 towards fluid outlet 4 deforms, and check valve is opened, and in-vehicle air is enable to be discharged, and reduces interior gas
Pressure.
By the way that position limiting structure is arranged towards 3 side of fluid inlet in elastic valve plate 2, elastic valve plate 2 can be limited towards stream
Side deformation where body entrance 3 makes feather valve by differential pressure action when body exterior Fluid pressure is greater than interior of body
Piece 2 contacted with position limiting structure it is closer so that fluid outlet 4 can not be connected to fluid inlet 3 in this case, so as to
It prevents body exterior fluid from flowing by check valve interior, plays the role of one-way sealing, ensure that the sealing performance of vehicle body.
