Abstract
The utility model provides an airtightness detection apparatus comprising an air pipeline, a switch valve, a pressure-regulating valve, a pressure gauge, an air passage joint, and a connection board, an air source enters the box body by the air pipeline through the switch valve, the pressure-regulating valve, the pressure gauge, and the air passage joint, the air passage joint is connected with the connection board, and the connection board is connected with the box body in a sealing manner; and the airtightness detection apparatus is simple in structure, detection process is time saving and labor saving, high speed train electrical connector junction box bodies with poor sealing property can be detected by simple detection, generated faults and dangers brought by the faults in high speed train operation are prevented, and the performance of the airtightness detection apparatus is effective, fast, safe, and reliable.
Description
Technical field
The utility model relates to a kind of tightness test device, is specifically related to EMU electrical cnnector junction box casing tightness test device.
Background technology
The electrical cnnector junction box is mainly used in EMU, Main Function is to carry out separated time and wiring for the motor train unit active line of force, its casing generally is installed under the car, impermeability to casing requires very strict, if the impermeability of casing does not reach requirement, electrical equipment has the danger that is corroded in the casing, thereby causes being short-circuited or leaking electricity, easily initiation fire or cause personal injury.
Summary of the invention
In order to overcome above shortcoming, the utility model provides a kind of simple in structure, air-tightness detection device that can effectively detect the casing air tightness performance.
Casing air-tightness detection device described in the utility model, be connected with EMU electrical cnnector junction box casing, comprise gas pipeline, switch valve, pressure regulator valve, tensimeter, gas path joint, web joint, wherein switch valve, pressure regulator valve, tensimeter, gas path joint connect successively by gas pipeline, and gas path joint is connected with web joint.
During work, first web joint is connected with box sealing, then open switch valve, make and be filled with gas in the gas pipeline, source of the gas enters casing by gas pipeline by switch valve, pressure regulator valve, tensimeter, gas path joint, adjust pressure regulator valve and make the pressure in the gas pipeline reach setting, and from tensimeter, read numerical value and carry out air-tight test.If tensimeter numerical value is constant, represent that then EMU electrical cnnector junction box casing impermeability is good; If tensimeter numerical value changes, represent that then EMU electrical cnnector junction box box sealing is bad, need to be to further in detail leak detection of casing.
Casing air-tightness detection device described in the utility model, simple in structure, testing process is time saving and energy saving, just the EMU electrical cnnector junction box casing of poor sealing can be detected by easy detection, the danger of having broken down and having brought when having avoided the EMU operation has efficiently convenient, safe and reliable performance.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Each piece number explanation among the figure:
The 1-gas pipeline; The 2-switch valve; The 3-pressure regulator valve; The 4-tensimeter; The 5-gas path joint; The 6-web joint; The 7-casing; The 8-source of the gas.
Embodiment
In conjunction with Fig. 1, casing air-tightness detection device described in the utility model is elaborated.
As shown in Figure 1, frock described in the utility model, comprise gas pipeline 1, switch valve 2, pressure regulator valve 3, tensimeter 4, gas path joint 5, web joint 6, wherein source of the gas 8 enters casing 7 by gas pipeline 1 by switch valve 2, pressure regulator valve 3, tensimeter 4, gas path joint 5, gas path joint 5 is connected with web joint 6, and web joint 6 is tightly connected with casing 7.
During work, opening switch valve 2 makes in the gas pipeline 1 and is filled with gas, adjusting pressure regulator valve 3 makes the pressure in the gas pipeline 1 reach setting, and from tensimeter 4, read numerical value, then gas path joint 5 is connected with web joint 6, web joint 6 is tightly connected with casing 7, gas is filled with casing 7 again, carries out air-tight test.
