Abstract

The invention belongs to the technical field of pipeline detection, and particularly relates to a connecting pipe air tightness detection device which comprises a supporting plate, a holding assembly and two detection assemblies. The holding assembly and the two detection assemblies are arranged on the supporting plate, an air outlet of a detection electromagnetic valve of each detection assembly is connected with one opening of a detection tee joint through an air pipe, and a second opening of the detection tee joint is connected with a barometer. The detection outer cylinder is connected to a cylinder push rod of the detection cylinder, the detection outer cylinder is provided with a long-strip hole, the detection inner cylinder is provided with an interface, the detection spring and the detection inner cylinder are sequentially installed in the detection outer cylinder, and the detection straight joint penetrates through the long-strip hole in the detection outer cylinder and is connected with the interface in the detection inner cylinder. A long connecting pipe is arranged at the end, away from the detection spring, of the detection inner cylinder and penetrates through the other end of the detection outer cylinder, and a third opening of the detection tee joint is connected with the detection straight joint through an air pipe. According to the invention, automatic detection of the air tightness of the connecting pipe is realized, and the detection quality is improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection, and in particular relates to an airtightness detection device for connecting pipes. Background technique [0002] Connecting tubes are widely used in the medical field, and are more frequently used in cardiology, interventional departments, anesthesia, and ICU. The connecting tube is used to connect other components such as catheters or high-pressure syringe syringes when injecting medicine, liquid or contrast medium to patients. [0003] A general connecting pipe consists of three parts: a conduit, an outer conical joint and an inner conical joint. The existing assembly method of the connecting pipe is manually bonded by workers, and the air tightness is checked after curing. The current detection method is: firstly plug the outer conical joint, and then connect the inner conical joint to the same air pipe with the air pressure gauge; add Air pressure, stand still for 10 seconds, an...
