Description

Technical Field

[0001] The utility model relates to the technical field of pipeline sealing detection, in particular to a pipeline structure sealing detection device for a refrigeration machine. Background Art

[0002] The working principle of a refrigerator is to rely on the absorption and discharge of refrigerant. Through the circulation of the refrigerant, the refrigerant is transported through pipelines, absorbing the heat of low-temperature objects and transporting it to high-temperature objects to achieve a cooling effect. Refrigerator is widely used in refrigeration fields such as air conditioners and refrigerators, and can provide people with a comfortable living environment.

[0003] Existing pipeline sealing detection devices detect the sealing of pipelines by sealing both ends of the pipeline and placing the pipeline in water to observe whether bubbles are generated in the pipeline. For example, Chinese patent application number CN202320460669.3 discloses an air-conditioning pipeline welding sealing detection device, which includes a base with a water pool fixedly installed above the base. The air-conditioning pipeline welding sealing detection device also includes a fixed frame, an electric telescopic rod, a clamping mechanism, a heating and cooling device, a thermometer, and a temperature display screen. The fixed frame is fixedly installed above the base, next to the water pool.

[0004] This device achieves a sealing effect by inserting a sealing plug into the pipe. Sealing by plugging in makes it difficult to seal pipes of different specifications, and after one side of the pipe is sealed, it is necessary to press the mounting plate so that the sealing plug on the other side can seal the pipe. When a large number of pipes need to be inspected, each pipe will need to press the corresponding mounting plate when sealing, affecting the inspection efficiency. Utility Model Content

[0025] During operation, the clamping plate 9 is pulled toward the direction of the mounting plate 4 on one side, the pipe is directly put on the fixed pipe 11, and the clamping plate 9 is pushed back to the initial position. The motor 6 drives the screw 7 to rotate, and the screw 7 drives the movable plate 8 to move, so that the clamping plate 9 moves toward the pipe. The clamping plate 9 will push the pipe, so that the connecting plate 5 and the clamping plate 9 clamp the two ends of the pipe, and the rubber sheets 10 on both sides will fit tightly with the two ends of the pipe, thereby sealing the pipe. The push rod 2 pushes the connecting frame 3 to move downward, so that the fixed pipe 11 is immersed in the water pool, and the air pump supplies gas to the fixed pipe 11.
