Liquid storage kettle airtightness detection device

Abstract

The invention discloses a liquid storage kettle airtightness detection device. The liquid storage kettle airtightness detection device comprises a detection housing, a piston, a sealing component, a pressure relief assembly, a linkage assembly, and a gas path connection housing; the piston is movably installed in the detection housing and can move up and down along the center line of the detectionhousing; the sealing component is fixed on the piston; two ends of the pressure relief assembly are fixedly connected with the piston and the linkage assembly respectively; the pressure relief assembly is used for preventing the sealing component from exerting excessive pressure on a liquid storage kettle; the linkage assembly abuts against the piston; the linkage assembly is used for making thepressure relief assembly to unfold or close with the movement of the piston; a sealing opening is formed in the sealing component; the gas path connection housing is fixed on the detection housing; agas transmission gas path is formed between the gas path connection housing and the detection housing; and the sealing opening is communicated with the gas transmission gas path. With the liquid storage kettle airtightness detection device of the invention adopted, the phenomenon of product deformation can be effectively prevented; and the airtightness of the liquid storage kettle can be effectively detected. The liquid storage kettle airtightness detection device is relatively simple in structure and can assist in reducing test costs.

Description

technical field [0001] The invention relates to a detection technology, in particular to an airtight detection device for a liquid storage pot. Background technique [0002] Containers such as kettles and oil pots have airtightness requirements and need to be tested for airtightness. During the test, it is necessary to fill in high-pressure gas from the mouth of the pot for testing. Therefore, various sealing fixtures are required to cooperate with the test during the test. The general sealing fixture uses the cylinder to drive the sealing head to descend and directly press on the bottle mouth to seal. This way of sealing will exert a certain pressure on the product body and may cause the product to deform and become unusable. The improved method is to use a mechanism to fix the position of the spout, and then use the cylinder to drive the sealing head to press down to the spout to achieve the sealing effect. This method solves the problem of product deformation, but the ...
