Description

TECHNICAL FIELD

[0002] The heat pipe is the heat supply pipe from the boiler room, direct combustion engine room, heat supply center and the like to the heat inlet of the building. The heat source heats the liquid in the radiator, and then the liquid is delivered to each household through the heat pipe network for heating. The heat pipe network is formed by laying and connecting the bodies of multiple heat pipes. Before laying, the air tightness of the heat pipe needs to be detected to prevent the liquid in the heat pipe from flowing out during use and causing heat loss. The heat pipe is usually tested for air tightness using the positive pressure method. The positive pressure method is to seal and inflate the heat pipe using an air tightness detection device, and then to observe the pressure change using an air tightness detector to determine the leakage amount and further infer whether the air tightness of the heat pipe is qualified.

However, there are safety hazards during the lifting of the pipe, and frequent lifting can cause the operator to be overworked. The air tightness detection device is connected to the heat pipe by flange connection, but the connection and disconnection process is complicated, there are safety hazards during lifting, and it cannot meet the detection requirements of pipes of different sizes, thereby causing inconvenience in use.
