Description
Technical field
The present invention is specifically related to a kind of helium recovery unit.
Background technique
In existing ultra-low temperature container testing property, usually can adopt a kind of inert gas of costliness---helium, as tested media, in test process, can consume a large amount of helium, these helium are all directly emptied in air, cause waste, add such Product checking cost simultaneously; So need a kind of helium recovery unit badly to solve the problem.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of helium recovery unit, this helium recovery unit can solve the problem well.
For reaching above-mentioned requirements, the technological scheme that the present invention takes is: provide a kind of helium recovery unit, and this helium recovery unit comprises the high pressure tank, low pressure gasholder and the liquid nitrogen case that are interconnected; Liquid nitrogen case inside is provided with detected member, and suction port and the air outlet of low pressure gasholder are all connected to pneumatic filter, and high pressure tank is connected to pressure pan pressure relay, is connected to suction booster between high pressure tank and low pressure gasholder.
The advantage that this helium recovery unit has is as follows:
The helium recovery that this helium recovery unit will directly be discharged in air originally by arranging the parts such as low pressure pressure tank relay, pressure pan pressure relay and pneumatic filter, recycles, thus reduces the testing cost of this series products.With regard to testing cost, after using this device, for different products, the highlyest reduce testing cost more than 50%.
