Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure: 1. the device comprises a component to be detected, 2, a liquid pipeline, 3, a doubly-linked gas collecting ball, 4, a liquid differential pressure meter, 41, a U-shaped glass tube, 42, a scale, 5, a pressure meter, 6, a hydraulic test board, 7, a control valve, 8 and a pipeline connecting piece.
Detailed Description
As shown in figure 1, a low pressure test device for automobile brake system component leakage detection comprises a hydraulic test board 6 and a liquid differential pressure gauge 4, wherein a component 1 to be detected, a liquid pipeline 2, a pressure gauge 5, a control valve 7 and a doubly-connected gas collecting ball 3 are vertically arranged on the hydraulic test board 6.
The left end of the liquid pipeline 2 is communicated with the component 1 to be detected, the right end of the liquid pipeline 2 is communicated with the liquid differential pressure meter 4, and the lower end of the middle part of the liquid pipeline 2 is communicated with the doubly-connected gas collecting ball 3 through the control valve 7.
And a pressure gauge 5 is arranged on the liquid pipeline 2 and used for assisting pressure measurement.
The hydraulic test board 6 and the liquid differential pressure meter 4 are both positioned on the same vertical plane.
The liquid pipeline 2 is fixed on the hydraulic test board 6 through a pipeline connecting piece 8.
The double gas collecting bulb 3 is used for quantitative pressurization.
The liquid differential pressure gauge 4 comprises a U-shaped glass tube 41 and a scale 42 arranged between the U-shaped glass tube 41, and the right end of the liquid pipeline 2 is communicated with the U-shaped glass tube 41.
The working process is as follows: before detection, the control valve 7 is opened to directly communicate the liquid pipeline 2 with the doubly-connected gas collection ball 3 for quantitative pressurization, then the control valve 7 is closed, and the liquid pipeline 2 and the doubly-connected gas collection ball 3 are disconnected for detection; the liquid line 2 in turn influences the differential liquid pressure gauge 4, the liquid level difference of the differential liquid pressure gauge 4 changing when the brake fluid of the component 1 to be detected leaks.
