Abstract
A brake chamber diaphragm with a sealing ring belongs to a component in an automobile air brake system. The defects that the clamping force is large and air leakage is easy to occur in the sealing of the existing brake chamber diaphragm because the sealing of the existing brake chamber diaphragm is in surface contact with the contact surface between the existing brake chamber diaphragm and the upper shell and the lower shell are mainly solved. The utility model comprises a diaphragm body, wherein the upper and lower surface sealing parts of the diaphragm body are provided with convex sealing rings. The utility model discloses a set up convex sealing ring, make brake chamber diaphragm become the line contact with the contact of upper and lower casing by the face contact, not only can obviously improve brake chamber's sealing performance, simple structure, simple to operate moreover.
Description
Technical field
The utility model belongs to the parts in the Automobile air brake system.
Background technology
Brake operating diaphragm is the critical component in the Automobile air brake system, and its sealing is gone up lower house by the clip chucking and realized.Contact because contacting between brake operating diaphragm and the last lower house is face, therefore, not only required gripping power is big, and its easy gas leakage.
Summary of the invention
The purpose of this utility model is to provide the brake operating diaphragm that has seal ring at above-mentioned deficiency, can obviously improve the sealing property of compressed air brake cylinder.
The utility model is achieved in that and comprises the diaphragm body, it is characterized in that male adapter has been played at the upper and lower surface sealing position of said diaphragm body.
Above-mentioned male adapter is two male adapters that are parallel to each other.
The utility model is by setting up male adapter on former brake operating diaphragm, making it is to contact with housing by seal ring when contacting with last lower house, promptly, not only can obviously improve the sealing property of compressed air brake cylinder by original face contact becoming line contact, and simple in structure, easy for installation.
Description of drawings
Fig. 1 is the utility model structural profile scheme drawing.
Fig. 2 is the utility model installing condition scheme drawing.
---diaphragm body, 2---male adapter, 3---upper shell, 4---lower house, 5---clip among the figure: 1.
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: two male adapters that are parallel to each other 2 are played at the upper and lower surface sealing position of diaphragm body 1 promptly becomes the utility model.
During installation, the contact surface between diaphragm body 1 and upper shell 3 and the lower house 4 (promptly sealing the position) is two male adapters 2 by its upper and lower surface, promptly by original face contact becoming line contact, can obviously improve the sealing property of compressed air brake cylinder.
Claims (2)
1, a kind of brake operating diaphragm that has seal ring comprises the diaphragm body, it is characterized in that male adapter has been played at the upper and lower surface sealing position of said diaphragm body.
2,, it is characterized in that said male adapter is two male adapters that are parallel to each other by the described brake operating diaphragm that has seal ring of claim 1.
