Technical field
The utility model belongs to a kind of air tightness test technical field, and in particular to a kind of quick airtight test dress of babinet
It sets.
Background technology
Currently, due to babinet service life either poor sealing performance and lead to the interior leakage or leakage of medium, can cause
Environmental pollution and economic loss can cause the generation of safety accident when serious.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of quick babinet in view of the above shortcomings of the prior art
Airtight test device, it is simple in structure, environment temperature is accurately controlled, improves precision, accuracy and the efficiency of detection, and in reality
Preferable effect is achieved in the application of border.
To realize the above-mentioned technical purpose, the technical solution that the utility model is taken is：
A kind of quick babinet airtight test device, wherein：Including air accumulator, regulating valve, pressure gauge, insulation cover, by measuring tank
Body, shut-off valve, flow valve, liquid nitrogen and incubator, the air accumulator are connect by pipeline with regulating valve, and the regulating valve is logical
It crosses pipeline to connect with pressure gauge, the pressure gauge is connect by pipeline with tested babinet, and the liquid nitrogen is filled in incubator
In, the tested babinet is immersed in liquid nitrogen, and the tested babinet is connect by pipeline with shut-off valve, and the shut-off valve is logical
It crosses pipeline to connect with flow valve, the insulation cover is mounted on the top surface of incubator, and the incubator is double using stainless steel
Layer structure and incubator central filler vacuum-powders insulation expanded perlite simultaneously add Photoresist aluminium powder.
To optimize above-mentioned technical proposal, the concrete measure taken further includes：
Idler wheel is installed on the bottom surface of above-mentioned incubator.
Pipeline between above-mentioned pressure gauge and tested babinet is made using seamless steel pipe.
Pipeline between above-mentioned tested babinet and shut-off valve is made using seamless steel pipe.
Liquid nitrogen is turned off manually when the liquid nitrogen level alarm in environmental chamber detects liquid nitrogen in the utility model.Insulating layer
For double-decked insulation, internal filled vacuum powder isolation expanded perlite simultaneously adds Photoresist aluminium powder, and thermal coefficient is little
In 0.03W/ (mK), liquid nitrogen tank uses stainless steel cryogenic box, and stainless steel inner container is corrosion-resistant anti-aging, and metal shell is prolonged resistance to
With castor convenience easy to remove is installed in bottom.Liquid nitrogen pipe belongs to ultralow temperature pipeline, must take into consideration low temperature when designing pipeline
The problem of liquid gasification and cold events, this equipment use the seamless steel pipe of 304 materials.Pipeline all using stainless-steel pipe,
Babinet is handled using carbon steel plastic-spraying, attractive and durable.
The utility model operating procedure is as follows：
(1) under normal temperature environment, it is passed through nitrogen, regulating valve is adjusted and is forced into nominal pressure to tested valve, detection valve exists
Room temperature seal performance；
(2) valve is put into the incubator equipped with cooling medium, keeps 15min, valve is impregnated, with thermocouple measurement valve
Door ensures that temperature is uniform everywhere；
(3) it is pressurized to nominal pressure to valve, the registration for observing flowmeter reads leak rate.
The utility model has the advantage of the followings：It is simple in structure, environment temperature is accurately controlled, the essence of detection is improved
Degree, accuracy and efficiency, and preferable effect is achieved in practical applications.
