Before leaving the factory, the liquid medicine and propellant (dimethyl ether or propane butane, etc.) are filled together. When in use, just press the control switch, and the liquid medicine will be driven by the propellant and sprayed out from the nozzle. The sealing of refrigerant aerosol cans needs to be sampled and tested during production.

At the same time, the conical seat is an inverted cone structure, and can seal aerosol tanks of different opening sizes during use, thereby realizing leak detection of aerosol tanks of different models, which is more flexible to use.

[0004] The above scheme adopts an immersion method to realize the air tightness detection of the refrigerant gas tank. However, due to the clamping structure of the above-mentioned leak detection device, the refrigerant gas tank needs to be completely immersed in the water of the leak detection tank during the air tightness detection process, resulting in a large amount of water droplets adhering to the outer surface of the refrigerant gas tank removed from the leak detection tank. Drying equipment is required to remove water in a targeted manner to prevent rust on the surface of the refrigerant gas tank.

[0005] To this end, a detection device for a refrigerant gas tank is proposed, which has the advantages of strong targeted gas tank air tightness detection and reduced water droplet adhesion, thereby solving the problems in the above-mentioned background technology. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a detection device for a refrigerant gas tank.

By starting the motor to drive the screw fixed at its output end to rotate, the guide seat drives the refrigerant gas tank clamped on the clamping frame to extend into the pool water of the detection pool during the movement of the threaded sleeve along the surface of the screw, so as to achieve the purpose of quick detection of the air tightness of the valve end of the refrigerant gas tank. Compared with the prior art, the method of facing the valve end of the refrigerant gas tank downward can reduce the adhesion of water droplets on the tank wall, and is conducive to improving the detection efficiency of the refrigerant gas tank.

[0029] Working principle:

[0030] When in use, the refrigerant gas tank is inverted and close to the clamping frame 9, and then the cylinders 10 on both sides of the clamping frame 9 are started to extend, so that the two V-shaped clamps 18 clamp and fix the outer wall of the refrigerant gas tank, so that the valve end of the refrigerant gas tank faces the pool water of the detection pool 1. When the air tightness is tested, the screw 5 fixed at its output end is driven to rotate by starting the motor 4, so that the threaded sleeve 6 moves along the surface of the screw 5. During this process, the refrigerant gas tank clamped on the clamping frame 9 is driven by the guide seat 7 to extend into the pool water of the detection pool 1.

As the turnover cylinder 14 is pulled, the column 11 connected to one end of the telescopic rod 13 and the shaft seat 12 on the top of the detection pool 1 are rotated, so that the refrigerant gas tank on the turnover cylinder 14 is able to leave the range of the detection pool 1, which is convenient for the turnover and unloading of the refrigerant gas tank after the detection.
