Abstract
The utility model discloses a housing detection gas recovery device comprising a pipeline connected with a detected work piece. The pipeline is provided with a seventh value connected with a vacuum device. One branch of the pipeline is connected with one end of a gas storage tank by a first valve, and the other end of the gas storage tank is connected with one end of a low pressure tank by a fifth valve and a fourth valve sequentially. Another branch of the pipeline is connected with the other end of the low pressure tank by a second valve. Another branch of the pipeline is connected with the low pressure tank by a third valve and a mechanical pump. The low pressure tank is connected with a high pressure helium gas source device by a sixth valve, and a main compressor is disposed between the fifth valve and the fourth valve. The housing detection gas recovery device has advantages of simple structure, convenient use, and ability of reducing costs. By using the device, the helium gas recovery rate can reach 98%.
Description
Technical field
The utility model relates to gas concentration unit, is specifically related to housing and detects gas concentration unit.
Background technology
The airtight detection of existing shell workpiece adopts the helium of authorised pressure or dried compressed air that tested workpiece is carried out compressive resistance and leaks air tight test, to tested workpiece forvacuum and filled helium, finally detect the qualified and defective of measured workpiece, after the common detection of people is complete, can discharge helium, cost compare is high, and environment is produced pollution.
The utility model content
The technical problems to be solved in the utility model provides housing and detects gas concentration unit, can reclaim and detect the gas that is finished, and is simple in structure, easy to use.
For achieving the above object, the technical solution of the utility model is as follows:
