Description

Technical Field

[0001] This utility model relates to the field of switching valve technology, specifically to a dual-source heat pump switching valve installation device. Background Technology

[0002] A dual-source heat pump is a high-efficiency heat pump system that combines the advantages of air-source and ground-source heat pumps. It can flexibly switch between the two heat source modes according to external environmental conditions and energy utilization needs. An air-source heat pump absorbs heat from the air for cooling or heating, while a ground-source heat pump utilizes a stable heat source from underground soil or water for heat exchange. By operating these two heat sources in tandem, a dual-source heat pump selects the more efficient energy utilization mode under different seasons or operating conditions, thereby effectively improving the system's operating efficiency and energy-saving effect. In a dual-source heat pump system, the switching valve is one of the key components. Its main function is to switch between the two heat sources according to the system's operating status. However, because dual-source heat pumps involve multiple different piping connections, the installation and maintenance of the switching valve is often complex, requiring extremely high operational stability and sealing performance.

[0003] Utility model patent CN219639584U discloses an easy-to-install switching valve, including a switching valve body, a water pipe, and multiple connection ports on the switching valve body. A limiting device is provided on the switching valve body near the connection ports. The limiting device includes a rotating plate, with a rotating shaft fixedly connected to the bottom of the rotating plate. Connecting plates are rotatably connected to both ends of the rotating shaft, and the bottom of the connecting plates is fixedly connected to the switching valve body. A torsion spring is sleeved on the outer wall of the rotating shaft, with one end of the torsion spring fixedly connected to the connecting plate. With this easy-to-install switching valve, pressing the rotating plate causes the limiting block to lift, allowing the connecting pipe to be inserted into the connection port. Releasing the plate engages the limiting block with the limiting groove, thus fixing the water pipe to the switching valve. When maintenance or replacement of the switching valve is required, simply pressing the rotating plate removes the water pipe from the switching valve body, making installation and disassembly of the switching valve more convenient.

[0004] However, the existing technology described above uses a limiting block and a limiting groove to fix the water pipe, but this fixing method is prone to insufficient sealing in actual use. Because the force between the limiting block and the connecting piece is insufficient to pull the connecting piece towards the switching valve body, it cannot be ensured that the connection between the water pipe and the switching valve is always under pressure, posing a potential leakage risk. To address these issues, we propose a dual-source heat pump switching valve installation device, which can effectively improve sealing performance while simplifying installation and maintenance procedures. Utility Model Content

[0005] The purpose of this invention is to provide a dual-source heat pump switching valve installation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:
