Abstract
The utility model discloses a vehicle brake pipeline air-tightness detection device which comprises an air treatment pipeline; an inlet end of the air treatment pipeline is communicated with a power air interface of a factory, and an outlet end of the air treatment pipeline is communicated with an inlet end of a detection pipeline through a first shut-off valve; an outlet end of the detection pipeline is communicated with a vehicle brake pipeline; and the first shut-off valve and the inlet end of the detection pipeline are communicated with the outside through an exhaust pipeline. The vehicle brake pipeline air-tightness detection device has a simple structure, is easy to operate, is low in cost, is energy-saving and environmental-friendly, and can simultaneously detect the air-tightness of a plurality of brake pipelines.
Description
Technical field
The utility model relates to a kind of air-tightness detection device, particularly a kind of railcar bicycle brake piping air-tightness detection device.
Background technology
The brake system impermeability is a key point of railcar quality of production control, carries out pressurize, the pressure in factory's gas circuit need for during detection the cleaned air that charges into 1.0Mpa in the brake system; Be usually less than 1.0MPa, can't reach requirement, in order to satisfy testing requirements; All need use air compressor when detecting the vehicle impermeability in the past, and also need cooperate the dedicated test frock, air compressor belongs to electrical equipment; Cost is high, power consumption is high; Also not environmental protection, and maintaining is difficult, also has bigger potential safety hazard.
Summary of the invention
Goal of the invention: the purpose of the utility model is to overcome the deficiency of prior art, provide a kind of simply, railcar brake piping air-tightness detection device easily, improve the limitation that impermeability detects, simplify detection difficulty, the enhancing detection security.
Technical scheme: a kind of vehicle brake conduit air-tightness detection device; Comprise the air-treatment pipeline; The inlet end of said air-treatment pipeline is communicated with factory power wind interface; The outlet side of air-treatment pipeline is through the inlet end of the first block valve communication with detection pipeline, and the outlet side of said logical signal piping is communicated with vehicle brake conduit, and the inlet end of said first block valve and signal piping all is in communication with the outside through gas exhaust piping.
Further, said air-treatment pipeline comprises second block valve, air purifier, pressure charging valve and the reservoir that is communicated with successively; Said pressure charging valve is provided with exhaust box; The reservoir bottom is provided with draining valve.
Further, said air-treatment pipeline is arranged on the travelling car.
Further, between said air-treatment pipeline and the factory power wind interface first rapid-acting coupling is set.
Further, set gradually the 3rd block valve and tensimeter on the said signal piping; Second rapid-acting coupling is set between said signal piping and the vehicle brake conduit.
Further, on the said gas exhaust piping the 4th block valve is set.
Beneficial effect: the utility model is simple in structure, easily operation, and cost is low, and energy-conserving and environment-protective can detect the impermeability of multichannel brake piping simultaneously.
Description of drawings
Be illustrated as the structural representation of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done explanation further.
As shown in the figure; The utility model is included as vehicle brake conduit the air-treatment pipeline 1 that detects desired gas is provided; Said air-treatment pipeline 1 is arranged on travelling car; Like this can be so that pick-up unit be moved, the inlet end of air-treatment pipeline 1 is communicated with factory power wind interfaces through first rapid-acting coupling 9, and the outlet side of air-treatment pipeline 1 is through the inlet end of first block valve, 2 communication with detection pipelines 3.Signal piping 3 shown in the present embodiment comprises three branch roads; Every the branch road outlet side all is communicated with a vehicle brake conduit through second rapid-acting coupling 12, and the inlet end of said first block valve 2 and signal piping 3 each bar branch road all is in communication with the outside through gas exhaust piping 4.According to actual needs, the branch road of signal piping 3 can be provided with many.
Between the inlet end of air-treatment pipeline 1 and outlet side, set gradually second block valve 5, air purifier 6, pressure charging valve 7 and reservoir 8; Noise is bigger when considering pressure charging valve 7 work, is provided with exhaust box 14 above that; Be provided with draining valve 15 in reservoir 8 bottoms, be used for discharging the ponding of reservoir 8 inside.
Between the inlet end of signal piping 3 and outlet side, set gradually the 3rd block valve 10 and tensimeter 11.
The 4th block valve 13 is set on gas exhaust piping 4.
During device work; The air of factory power wind interface output original pressure gets into air purifier 6; Cleaned air passes gets into pressure charging valve 7; Pressure charging valve stores flowing to reservoir 8 behind 2～4 times of this supercharging airs, has produced one constantly at the output terminal with regard to air-treatment pipeline 1 like this and has satisfied the required pressure air of railcar air-tight test.Pressure air flows to each bar branch road of signal piping 3 respectively through first block valve 2; Detect the brake piping of vehicle through each bar branch road input; Come the air pressure of observation test vehicle brake conduit through the tensimeter on the branch road 11; After detection vehicle brake conduit inner air pressure reaches required value, close the 3rd block valve 10 of this test branch road, so just can change the impermeability that detects vehicle brake conduit through tensimeter 11 registrations.After detect finishing, close first block valve 2, open the 4th block valve 13 on the 3rd block valve 10 and the exhaust branch road 4 on signal piping 3 each bar branch road, just can drain and detect the interior pressure air of vehicle.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
