Abstract
The utility model discloses a device for detecting the air tightness of a brake pipe system compaction type fast-assembling pipe joint. The device is characterized by comprising a water tank connected with a drain pipeline; an air compressor connected with a main air-entraining pipe, which is provided with an air inlet valve and a pressure gauge and is connected with an air exhaust pipe provided with an air exhaust valve; and a plurality of branch connection pipes communicated with the tail end of the main air-entraining pipe, wherein each branch connection pipe is provided with a valve, each branch connection pipe penetrates through the wall of the water tank and penetrates into the inner part of the water tank, and the tail end of each branch connection pipe is connected with a to-be-detected compaction type fast-assembling pipe joint. Making use of the characteristic that compressed air generates bubbling reaction in water, the device determines whether a pipe joint is good by putting the pipe joint receiving an air tightness detection into the water tank, airing the pipe joint, and observing whether bubbles exist in the water tank or whether the pressure gauge has changes, is simple and easy in operation, and solves the problem of detecting the air tightness of the railway freight train brake pipe system compaction type fast-assembling pipe joint.
Description
Technical field
The utility model relates to a kind of air-tightness detection device, particularly about the air-tightness detection device of the fast holding pipe joint of braking pipe arrangement compression type.
Background technology
The bubble-tight detection of the fast holding pipe joint of railway freight-car braking pipe arrangement compression type is crucial in technological requirement, and national requirements detects the bubble-tight numerical value of braking pipe arrangement, and bubble-tight quality relates to the safety problem of railway freight-car in operational process.The detection method of being taked in the past is: after ready-packaged joint was compressed, suds were smeared on the surface, junction, and whether observe has bubble, if bubble is arranged then show gas leakage.The force value that traditional method can not be observed gas also is not easy to do the pressurize experiment.
Summary of the invention
Therefore, for the impermeability that solves railway freight-car (as: C80B, C70 type lorry) the fast holding pipe joint of braking pipe arrangement compression type detects problem, the utility model provides a kind of air-tightness detection device of pipe adapter accurately and fast.
For realizing above-mentioned purpose, the utility model is taked following technical scheme: the air-tightness detection device of the fast holding pipe joint of a kind of braking pipe arrangement compression type, and it is characterized in that: it comprises a tank, is connected with discharge pipe line on the tank, is marked with water in the said tank; One air compressor connects an aerating house steward, and said aerating house steward is provided with air intake valve and tensimeter, and on the aerating house steward, is connected with a gas outlet, and said gas outlet is provided with drain tap; End said aerating house steward is communicated with a plurality of branch tubes, and each said branch tube passes flume wall and extend into portion in the tank, remains to be done the fast holding pipe joint of compression type of detection in the end connection of said branch tube.On each said branch tube valve is installed all.
During detection, have or not bubble and pressure tabular value to have or not variation to judge that whether pipe adapter leaks gas in the tank through observing.
Utility model is owing to take above technical scheme; The beneficial effect that is had is: 1, the utility model utilization pressurized air has the characteristics of bubbling reaction in water; Put into tank with waiting the pipe adapter of doing the impermeability detection; In pipe adapter, ventilate, have or not bubble or tensimeter to have no change to judge the quality of joint in the observation tank.After using it can detect the assembling of braking pipe arrangement compression type pipe adapter easily and effectively whether gas leak phenomenon is arranged, and then guarantee the assembling quality requirement of Freight Car Braking System.2, in tank, a plurality of branch tubes can be set, connect a plurality of pipe adapters, on each branch tube, all be provided with valve, make each branch tube both can parallel connection use, also can use separately, once suppress and to detect a plurality of pipe adapters.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed description.
As shown in Figure 1, the utility model device comprises a tank 1, and the tank side is connected with discharge pipe line 2.Outer setting one air compressor at tank connects an aerating house steward 3 through air compressor, and aerating house steward 3 is provided with air intake valve 4 and tensimeter 5.On aerating house steward 3, also be connected with a gas outlet 6, gas outlet 6 has drain tap 7, and air intake valve 4 is opened during aerating, and drain tap 7 is closed; Drain tap 7 is opened during exhaust, and air intake valve 4 is closed.
End branch aerating house steward 3 goes out a plurality of branch tubes 8, all is equipped with valve 9 on each branch tube 8, makes that each branch tube both can while air inlet, also air inlet separately.Each branch tube 8 all passes flume wall and extend into portion in the tank.End at each branch tube 8 can connect the fast holding pipe joint 10 of compression type, and the fast holding pipe joint 10 of compression type just is meant the part of waiting to do air-tight test.
When doing the impermeability detection; At first on branch tube 8, install fast holding pipe joint 10, in tank, inject water then, water was not advisable to have pipe adapter; Close the Inlet and outlet water valve then; At the air intake valve of opening on air compressor and the aerating house steward 34, make pressurized air fill into fast holding pipe joint 10 through branch tube 8 then, this moment, drain tap 7 was closed.After force value meets the requirements of force value (like 1MPa), air intake valve 4 is closed, pressurize 1 minute, the bubble that whether has on every side of fast holding pipe joint 10 produces in the observation tank, and the value of tensimeter 5 has no change.If having bubble, the joint junction do not produce, and tensimeter numerical value no change, show that then impermeability is good.After detection finishes, open drain tap 7 gas is emitted, open draining valve, the decline of water table in the tank to below the pipe adapter lower surface, is pulled down joint at last.
Claims (2)
1. the air-tightness detection device of the fast holding pipe joint of braking pipe arrangement compression type, it is characterized in that: it comprises a tank, is connected with discharge pipe line on the tank, is marked with water in the said tank; One air compressor connects an aerating house steward, and said aerating house steward is provided with air intake valve and tensimeter, and on the aerating house steward, is connected with a gas outlet, and said gas outlet is provided with drain tap; End said aerating house steward is communicated with a plurality of branch tubes, and each said branch tube passes flume wall and extend into portion in the tank, remains to be done the fast holding pipe joint of compression type of detection in the end connection of said branch tube.
