Description

Technical Field

[0001] The utility model relates to the technical field of circulating water pump pipe networks, in particular to a two-way switching device for a centrifugal circulating water pump pipe network. Background Technique

[0002] Thermal energy storage refers to the storage of thermodynamic energy through corresponding devices. Thermal energy storage equipment is the basic equipment for solar thermal power generation, multi-source heat networks, and heat pump systems. The thermal energy storage industrial chain mainly includes thermal energy storage raw materials, thermal energy storage device products, complete sets of equipment and construction, facility operation and maintenance services, etc. The development priorities of the thermal energy storage industry include: molten salt thermal energy storage applicable to high-temperature thermal energy storage and its combination with solar thermal power generation, high-efficiency steam thermal energy storage facilities, and new thermal energy storage phase change materials.

[0003] With the growth of energy demand and the improvement of energy conservation and emission reduction requirements, the hot water storage tank system has received extensive attention because it can efficiently utilize various energy resources for thermal energy storage, and at the same time can supply heat to users by using the stored heat to improve the heat utilization efficiency. In this heating method, the hot water storage tank system plays a crucial role. It can store hot water from different heat sources for a long time and release heat when needed. However, the traditional single-flow water pump system cannot meet the complex requirements of the hot water storage tank system for heat storage and heat release, resulting in the need to equip each heat source with an independent water pump system to cooperate with the heat storage and heat release of the heat storage tank. This not only increases the equipment cost, but also makes the operation more complex and increases the workload of later maintenance, unable to meet the daily use requirements. Therefore, it is urgent to design a two-way switching device for a centrifugal circulating water pump pipe network to solve the above problems. Summary of the Invention

In this heating method, the hot water storage tank system plays a crucial role. It can store hot water from different heat sources for a long time and release heat when needed.

During daily use, by controlling the pump body and the second control ball valve at the pump pipeline, the pipeline switching flow operation of heat storage and heat release is realized. During the heat storage process, the central control system will open the electric valve connected to the selected heat source and start the water pump system to pump hot water into the heat storage tank for storage. During the heat release process, the central control system will close the electric valve connected to the heat source, open the valve connected to the heating system, and at the same time start the water pump system to pump the hot water in the heat storage tank out to supply heat.

The central control system is responsible for intelligently controlling the on-off states of these electric valves according to actual requirements to achieve the matching of the heat source and the heat storage or heat release requirements of the heat storage tank system.

[0023] An upper flow-through pipeline 5 and a lower flow-through pipeline 6. One end of the first flow-through pipeline 2 and the second flow-through pipeline 3 is provided with the upper flow-through pipeline 5. A lower flow-through pipeline 6 is arranged on the side surface of one side of the first flow-through pipeline 2 and the second flow-through pipeline 3. A gas boiler 7 is arranged at one end of the upper flow-through pipeline 5. An electric boiler 8 is arranged at one end of the lower flow-through pipeline 6. A first connection ball valve 9 is arranged between the upper flow-through pipeline 5 and the first flow-through pipeline 2 and the second flow-through pipeline 3. A second connection ball valve 10 is arranged between the lower flow-through pipeline 6 and the second flow-through pipeline 3 and the second flow-through pipeline 3. The hot water in the heat storage tank 1 is pumped out to supply heat.

According to this information, the control system intelligently controls the on-off states of the electric valves and the operation of the water pump system to achieve the optimal matching of the heat source and the demand of the heat storage tank system.

[0024] Working principle: When in use, first, the heat storage tank 1 is connected through the first flow pipeline 2 and the second flow pipeline 3. The gas boiler 7 and the electric boiler 8 are respectively connected through the upper flow pipeline 5 and the lower flow pipeline 6. Under the control of the first connecting ball valve 9 and the second connecting ball valve 10, the two are switched and connected bidirectionally in the water pump pipe network.

Each heat source-coupled heat storage tank system is connected to the water pump system through a group of electric valves. The central control system is responsible for intelligently controlling the on-off states of these electric valves according to actual needs to achieve the matching of the heat source and the heat storage or heat release requirements of the heat storage tank system. During daily use, by controlling the pump body 13 and the second control ball valve 14 at the pump pipeline 4, the pipeline switching flow operation of heat storage and heat release is realized. During the heat storage process, the central control system will open the electric valve connected to the selected heat source and start the water pump system to pump hot water into the heat storage tank 1 for storage. During the heat release process, the central control system will close the electric valve connected to the heat source, open the valve connected to the heating system, and at the same time start the water pump system to pump the hot water in the heat storage tank 1 out to supply heat. The control system monitors the states of each heat source, the water level and temperature of the heat storage tank 1, and the requirements of the heating system in real time. Based on this information, the control system intelligently controls the on-off states of the electric valves and the operation of the water pump system to achieve the optimal matching of the heat source and the heat storage tank system requirements.
