Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing to this
Utility model embodiment is described in further detail.
See Fig. 1, the vacuum boost system sensor of a kind of integrated check valve, have:
Housing 1；
The module 2 being arranged on housing 1；
As shown in Figures 2 and 3, the mounting seat 5 being arranged on housing 1, mounting seat 5 is provided with annular groove 51；
Annular groove 51 is provided with the through hole 53 connected with module 2；The inner side of annular groove 51 is towards housing 1 inner recess；
It is arranged in annular groove 51, can close the diaphragm 4 of through hole 53；
The valve 3 being connected with mounting seat 5, valve 3 is provided with the jacking block 31 of spacing diaphragm 4, diaphragm 4
Thickness makes there is gap between the inner side of annular groove 51 and jacking block 31.
The sealing means of vacuum boost system sensor, its concrete technical scheme is the design of this structure and diaphragm 4
Combining of type selecting:
A) diaphragm 4 is assemblied in the structure of housing 1 is six pore structure uniform Design, it is ensured that diaphragm 4 is assemblied in shell
On body 1, negative-pressure sucking is uniform, it is ensured that sealing is good；
B) the thickness design of diaphragm 4, with the degree of depth and the end face a size of gap of valve 3 of the concave surface in six-hole ball face
Coordinating, valve 3 end faces-jacking block 31 fixes spacing diaphragm 4 installation dimension, so that the sealing of diaphragm 4
Can long time stability；
C) material of diaphragm 4 is containing polyfluoroprene, has " king of rubber " title, and the corrosion resistance of fluorine is strong, high/low temperature
In the case of, stiffness changing is the least, makes diaphragm 4 same sealing under high and low temperature environment good.
Annular groove 51 center is provided with connection post 52；Jacking block 31 is provided with screwed hole, connects post 52 and screwed hole
Threaded.
Through hole 53 has six, is uniformly distributed in annular groove 51.Housing 1 is six hole housings 1 in design structure
The overall structure in face is concave shape, and diaphragm 4 diameter dimension accords with completely with the spherical diameter of housing 1 six hole concave surface
Closing, valve 3 end face fixes spacing diaphragm 4 installation dimension, so that diaphragm 4 positions in the structure,
The sealing performance steady in a long-term making sensor is good.The thickness design of diaphragm 4, with housing 1 six-hole ball face
The degree of depth of concave surface and the end face a size of matched in clearance of valve 3, steam can design from housing 1 concave structure
Place is oozed out, under humidity environment, and favorable sealing property.
In the case of negative pressure, diaphragm 4 can be adsorbed closing through hole 53, it is achieved seals, when wetly,
Dampness can ooze out from the gap location between the inner side of annular groove 51 and jacking block 31.
Diaphragm 4 material is containing polyfluoroprene.In the case of high/low temperature alternation, diaphragm 4 hardness will not change,
Make diaphragm 4 same sealing under high and low temperature environment good.
Condenser welding is connected in module 2, and module 2 is bonded on housing 1.
Module 2 is EP2508C.
Use technique scheme, it is possible to achieve the stability of the sealing of product, additionally exist when the environment measured
Just under epidemic disaster rugged environment, the overall structure in six faces, hole of housing 1 is concave shape, and diaphragm 4 is straight
Footpath size complies fully with the spherical diameter of six hole concave surfaces, and steam can ooze out at concave structure design, makes film
The sealing property of sheet 4 under high and low temperature environment, wet environment seal performance still good, sealing property is stable.
Above in conjunction with accompanying drawing, this utility model is exemplarily described, it is clear that this utility model implements
It is not subject to the restrictions described above, as long as have employed method of the present utility model design and technical scheme is carried out
