The invention discloses a high-precision gas leakage detection device and method. The high-precision gas leakage detection device comprises a mixture gas source container, wherein the mixture gas source container is used for holding a leakage detection gas and a leakage detection substance; a detection tube, wherein the first end of the detection tube is connected with the mixture gas source container and the second end of the detection tube is suitable to be connected with a member to be detected, at least one of the mixture gas source container and the detection tube being provided with an inlet valve; an exhaust pipe, wherein the first end of the exhaust pipe is connected with the detection tube and the first end of the exhaust pipe is arranged between the inlet valve and the second end of the detection tube, and the exhaust pipe is provided with an outlet valve; an air-pressure detection member, wherein the air-pressure detection member is connected with the portion, arranged between the inlet valve and the second end of the detection tube, of the detection tube; and a leakage detector, wherein the leakage detector is suitable to close to the member to be detected for detecting the leakage detection substance. The high-precision gas leakage detection device in the invention has the advantages of being high in detection precision, simple in structure and convenient to operate, and being capable of detecting leakage points and the like.
Description
technical field [0001] The invention relates to the technical field of leak detection, in particular to a high-precision gas leak detection device and a high-pressure gas element leak detection method. Background technique [0002] Water dispensers, air conditioners, refrigerators and other products need to be sealed and leak tested before leaving the factory. In order to solve the problems of high false detection rate and many process flows of traditional high-pressure gas detection, some equipment adopts the method of gas detection and brushing foam to judge whether the product leaks, but the detection accuracy is low and the leakage point cannot be detected. There are also some devices that incorporate a variety of leak detection methods in order to improve accuracy, but the structure of the device is too complicated and the operation is very cumbersome. Contents of the invention [0003] The present invention aims at solving one of the above technical problems at leas...
