Description

Technical Field

[0001] This utility model relates to the field of fluorine connection pipe technology, and in particular to a direct-heating water-electricity separation air-source fluorine connection pipe fixing device. Background Technology

[0002] The core components of a fixed air-source heat pump fluorine connection pipe are specialized pipe clamps and supports, which are typically made of corrosion-resistant materials. They securely support the pipe to the wall or structure at specific intervals. Their main functions are to bear the weight of the pipe, absorb equipment vibration, prevent pipe displacement and friction, maintain the necessary slope, and protect the pipe and insulation layer from external damage, ensuring long-term stable, reliable, and quiet operation of the system.

[0003] Existing direct-heating water-electricity separation air source refrigerant connection pipe fixing devices use mechanical fixing to constrain pipe displacement and counteract the vibration effects during equipment operation. However, due to the difficulty in locking the pipes, vibration and loosening will gradually intensify during long-term equipment operation, leading to slow refrigerant leakage. Utility Model Content

One end of the second compression spring 72 is stuck under the pressure plate 73, and the other end of the second compression spring 72 is stuck between the toothed grooves of the second toothed nut 71. The pressure plate 73 is provided with two screw holes. The end of the second screw 74 is fixedly connected to the protective shell 7.
