Air tightness detection equipment for anti-freezing water faucet and detection method of air tightness detection equipment

Abstract

The invention discloses detection equipment, and particularly relates to anti-freezing faucet airtightness detection equipment, which is technically characterized by comprising a tubular part with air vents at two ends, a positioning assembly used for fixing the tubular part and introducing gas into the tubular part, and a sealing assembly used for blocking and sealing the tubular part, the device further comprises a gas supply device used for providing gas, the positioning assembly comprises a hollow positioning rod, the surface of the positioning rod is provided with an exhaust hole used for ventilating the tubular part, and the sealing assembly comprises a telescopic part used for stretching out and drawing back in the axial direction of the positioning rod. The telescopic end of the telescopic part is provided with an axial sealing plug used for sealing a ventilation opening in one side of the tubular part, a sealing plug piece used for sealing a ventilation opening in the other side of the tubular part is arranged outside the positioning rod, and the device further comprises an air pressure sensor connected with the positioning rod in parallel and communicated with an air supply device. According to the invention, the air tightness of the tubular part can be efficiently detected by observing the change of the internal air pressure.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an airtightness detection device of an antifreeze faucet and a detection method thereof. Background technique [0002] At present, in the production process of the faucet, the air-tightness test of the tubular parts of the faucet is usually carried out by means of ventilation and immersion in order to avoid the liquid side leakage of the faucet during use, that is, by closing the two ends of the tubular parts and ventilating them After being pressurized, it is immersed in water, and the air-tightness of the tubular parts is judged by observing whether there are bubbles emerging from the water surface. This method is cumbersome to operate and has low detection efficiency. Increase the labor intensity of workers. [0003] In addition, Chinese Utility Model Patent Publication No. CN205534299U discloses an antifreeze faucet, comprising a faucet body, a water pipe is provided at th...
