A kind of vehicle braking rescue converting device test tool, including, sequentially connected blast pipe, pressure regulator valve, shut-off valve, Cylinder and discharge pipe, and the support frame for fixing above-mentioned component;Be additionally provided between shut-off valve and cylinder an exhaust valve and Pressure gauge, the blast pipe are connect with external ventilation apparatus, and the air inlet of the exhaust valve and pressure gauge is connected with cylinder, row The gas outlet of air valve is connected with outside atmosphere.
Further, the gas outlet of the shut-off valve is connect with exhaust valve, pressure gauge and cylinder respectively by a four-way pipe.
Further, the exhaust valve is needle valve.
Further, the pressure regulator valve is filtering pressure reducing valve.
Further, a handle is also fixed on the cylinder.
Further, support frame as described above has former and later two support ends, and connect respectively with blast pipe and discharge pipe.
Further, the blast pipe, pressure regulator valve, shut-off valve, cylinder and discharge pipe are located on same axis.
After technical solution described in the utility model, bring it is following the utility model has the advantages that
1, the utility model is compact-sized is not easy to reveal, and maintains easily, reduces maintenance cost;
2, the utility model is by the pressure in exhaust valve regulation cylinder, and exhaust valve uses needle valve, and degree of regulation is high, It can stablize, accurately export BP wind pressure signal;
3, the utility model structure is simple, simple and quick, improves work efficiency;
4, the overall dimensions of the utility model are small, light-weight to avoid generating vibration with portable movement.
Detailed description of the invention
Fig. 1: the main view of the utility model;
Fig. 2: the top view of the utility model;
Wherein: 1, blast pipe 2, pressure regulator valve 3, shut-off valve 4, cylinder 5, discharge pipe 6, support frame 7, exhaust valve 8, Pressure gauge 9, handle 10, four-way pipe.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
