Technical Field

[0001] This utility model relates to the field of heat pump technology, specifically a novel water pipe connection structure for swimming pool heat pumps. Background Technology

[0002] A heat pump is a highly efficient and energy-saving device that makes full use of low-grade heat energy. The working principle of a heat pump is to force heat from a low-temperature object to a high-temperature object in a reverse circulation manner. It consumes only a small amount of net reverse circulation work to obtain a large amount of heat supply, and can effectively utilize low-grade heat energy that is difficult to apply to achieve the purpose of energy saving.

[0003] Heat pump water pipe connections often use standard flange connections. However, traditional threaded connections of standard flanges are prone to stripping, improper torque leading to leakage, and direct connection of the heat pump's inlet and outlet to rigid pipes can cause vibration transmission and failure to release thermal stress.

[0004] There is an urgent need for a new type of water pipe connection structure for swimming pool heat pumps to address the technical deficiencies mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel water pipe connection structure for a swimming pool heat pump, comprising a heat pump water pipe, a shock-absorbing component, a stabilizing component, a sealing component, and a connecting water pipe. A movable flange is fixedly installed externally on the heat pump water pipe, and mounting bolts are installed on the movable flange. The shock-absorbing component includes a rubber flexible joint, which is installed between the heat pump water pipe and the connecting water pipe. The stabilizing component includes a butterfly flange, which is fixedly installed at the inlet of the connecting water pipe, and connecting bolts are provided on the butterfly flange. The sealing component is located at the outlet of the heat pump water pipe and the inlet of the connecting water pipe.

[0007] As a further technical solution of this utility model, a first connecting flange is fixedly connected to the top end of the rubber flexible joint, and a second connecting flange is fixedly connected to the bottom end of the rubber flexible joint. A first sealing ring is fixedly installed inside both the first connecting flange and the second connecting flange.

[0008] As a further technical solution of this utility model, the first connecting flange is connected to the butterfly flange and fixed by connecting bolts.

[0009] As a further technical solution of this utility model, the second connecting flange is connected to the movable flange and fixed by mounting bolts.

[0010] As a further technical solution of this utility model, the thread of the connecting bolt passes through the bolt hole of the butterfly flange, and the bolt hole of the butterfly flange contains bolt sealant.

[0011] As a further technical solution of this utility model, the sealing assembly includes a second sealing ring, which is fixedly connected to the connector of the heat pump water pipe.

[0012] As a further technical solution of this utility model, the sealing assembly includes a first O-ring and a second O-ring, which are fixedly installed on the butterfly flange.

[0013] As a further technical solution of this utility model, both the first O-ring and the second O-ring are made of rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the new water pipe connection structure for swimming pool heat pumps not only realizes the function of reducing vibration transmission and enhancing connection stability, but also realizes the function of improving sealing performance; By setting up shock-absorbing components, rubber flexible joints, a first connecting flange, a second connecting flange, and a first sealing ring, a rubber flexible joint is installed at the connection between the heat pump water pipe and the connecting water pipe. The first connecting flange of the rubber flexible joint is connected to the butterfly flange of the connecting water pipe, and the second connecting flange is connected to the movable flange of the heat pump water pipe. As a connecting component, the rubber flexible joint can effectively absorb the vibration and noise of the unit operation, prevent it from being transmitted to the rigid pipeline, absorb the stress generated by the thermal expansion and contraction of the pipeline, and prevent the support or connection from cracking under stress. By incorporating stabilizing components, butterfly flanges, connecting bolts, and bolt sealant, the flanges on the heat pump water pipes, connecting water pipes, and vibration damping components all adopt butterfly flanges. During connection, connecting bolts are used to fix the flanges together, and bolt sealant is filled at the connection points of the connecting bolts. It can completely fill the thread gaps, form a seal after curing, and has a locking and anti-loosening function. It is suitable for vibrating environments, and the connection stability of this structure is good. By incorporating a sealing assembly, a second sealing ring, a first O-ring, and a second O-ring, both the outlet of the heat pump water pipe and the inlet of the connecting water pipe are equipped with a sealing assembly. The outlet of the heat pump water pipe is equipped with a second sealing ring, and the inlet of the connecting water pipe is equipped with a first O-ring and a second O-ring.
