Description

Technical Field

[0001] This utility model relates to the field of heating pipe network technology, and more specifically, to a regulating device for hydraulic balance of heating pipe networks. Background Technology

[0002] Hydraulic balancing in a heating network refers to the process of adjusting the resistance of each branch of the network to distribute flow according to demand under design conditions, meeting the needs of terminal equipment and ensuring the normal operation of the system. The core purpose of hydraulic balancing is to prevent uneven flow from causing overheating or undercooling in some areas, thereby achieving both comfort and energy efficiency in the system.

[0003] A search revealed that utility model patent CN214619763U discloses a hydraulic balance regulating device for a heating network, comprising a shell, an automatic pressure relief component, and a storage and pressurization component. The automatic pressure relief component is located inside the shell, and the storage and pressurization component is connected to the shell. The automatic pressure relief component includes a pressure relief chamber, a moving block, a compression spring, and a fixed block. The storage and pressurization component includes a water tank support, a water storage tank, a drain pipe, and an overflow valve. The drain pipe is located on the upper end of the pressure relief chamber and has an inlet, and the moving block is located directly below the inlet. This device is a hydraulic balance regulating device for a heating network that can automatically relieve pressure when the pressure in the network is too high, temporarily recover and reuse the released excess supply water, and pressurize when the pressure is too low.

[0004] However, the aforementioned patents have the following shortcomings: although they can release pressure, it is not convenient to control the pipeline pressure after pressure release; also, when the depressurized water flows into the storage tank, heat will be lost if the system is not used for a long time, affecting subsequent use; furthermore, it is not convenient to pressurize when the pressure in the heating pipe is too low. Therefore, we propose a hydraulic balancing regulating device for heating pipe networks. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a regulating device for hydraulic balance of heating pipe network.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A hydraulic balancing regulating device for a heating network includes a main heating pipe, a main return pipe, and indoor heating pipelines. The main return pipe is equipped with multiple return mechanisms. Multiple heating branch pipes are fixedly connected to the main heating pipe. Multiple pressure relief pipes are fixedly connected to the main heating pipe. Multiple inlet pipes are fixedly connected to the sides of each of the heating branch pipes. The ends of each inlet pipe are connected to the inlets of the indoor heating pipelines. A pressurizing mechanism is installed between each heating branch pipe and each inlet pipe. A pressure relief pump is fixedly installed at the top of each inlet pipe. The input end of the pressure relief pump extends into the inner cavity of the inlet pipe. A pressure relief pipe is fixedly connected to the output end of the pressure relief pump. The end of the pressure relief pipe is fixedly sleeved into the inner cavity of the pressure relief main pipe. A water pressure monitoring instrument is fixedly installed at the top of one end of each inlet pipe, and a controller is installed at the bottom of the inlet pipe.

[0008] As a preferred embodiment of this utility model, the pressurizing mechanism includes a booster pump fixedly installed at the bottom of the inlet pipe, the output end of the booster pump extending into the inner cavity of the inlet pipe, the input end of the booster pump being fixedly connected to a water pumping pipe, and the end of the water pumping pipe being fixedly sleeved into the inner cavity of the heating branch pipe.

[0009] As a preferred embodiment of this utility model, the water return mechanism includes a water return branch pipe fixedly connected to the water return main pipe, and multiple drain pipes are fixedly connected to the side of the water return branch pipe. The multiple drain pipes are respectively connected to the drain outlets of multiple indoor heating pipelines.

[0010] As a preferred embodiment of this utility model, the input end of the pressure relief pump is inclinedly sleeved into the inner cavity of the inlet pipe, and the inclination direction of the input end of the pressure relief pump is the same as the direction of water flow in the inlet pipe.

[0011] In a preferred embodiment of this utility model, the output end of the booster pump is inclinedly sleeved into the inner cavity of the inlet pipe, and the inclination direction of the output end of the booster pump is the same as the water flow direction in the inlet pipe.

[0012] In a preferred embodiment of this utility model, the water pressure monitor, booster pump, pressure relief pump, and controller are all powered by the user's indoor power supply.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, a water pressure monitor is used to monitor the water pressure in the indoor heating pipeline introduced by the inlet pipe in real time. When the water pressure monitor detects that the pressure is too high, a portion of the water in the inlet pipe is pumped back to the heating main pipe by the cooperation of the pressure relief pump, pressure relief pipe and pressure relief main pipe. This realizes the pressure relief treatment of the inlet pipe and the hot water pumped back to the heating main pipe can continue to be used by subsequent users, thus improving the practicality of the regulating device.

[0015] (2) In this utility model, when the water pressure monitor detects that the water pressure in the inlet pipe is too low, the booster pump generates suction in the pumping pipe, and the pumping pipe is used to pump the hot water in the heating branch pipe. At the same time, the hot water is pressurized. The pressurized hot water mixes with the hot water in the inlet pipe, increasing the water pressure in the inlet pipe and ensuring the hydraulic balance in the latter part of the inlet pipe.

The return water main pipe 2 is equipped with multiple return water mechanisms 3. Multiple heating branch pipes 4 are fixedly connected to the main heating pipe 1. Multiple pressure relief main pipes 8 are fixedly connected to the main heating pipe 1. Multiple inlet pipes 5 are fixedly connected to the sides of each heating branch pipe 4. The ends of each inlet pipe 5 are connected to the inlet of the indoor heating pipeline 6. A pressurizing mechanism 7 is provided between each heating branch pipe 4 and each inlet pipe 5. A pressure relief pump 9 is fixedly installed at the top of each inlet pipe 5. The input end of the pressure relief pump 9 extends into the inner cavity of the inlet pipe 5. A pressure relief pipe 10 is fixedly connected to the output end of the pressure relief pump 9. The end of the pressure relief pipe 10 is fixedly sleeved into the inner cavity of the pressure relief main pipe 8. A water pressure monitoring instrument 11 is fixedly installed at the top of one end of each inlet pipe 5. A controller 12 is provided at the bottom of each inlet pipe 5.

[0026] In this embodiment, the controller 12 is electrically connected to the pressure relief pump 9, the booster pump 13 and the water pressure monitor 11 respectively. The controller 12 processes the pressure signal detected by the water pressure monitor 11 and controls the pressure relief pump 9 and the booster pump 13.

[0027] For details, please refer to Figures 1 to 4 The pressurizing mechanism 7 includes a booster pump 13 fixedly installed at the bottom of the inlet pipe 5. The output end of the booster pump 13 extends into the inner cavity of the inlet pipe 5. The input end of the booster pump 13 is fixedly connected to a water pumping pipe 14. The end of the water pumping pipe 14 is fixedly sleeved into the inner cavity of the heating branch pipe 4.

[0028] For details, please refer to Figure 1 and Figure 2 The return water mechanism 3 includes a return water branch pipe 16 fixedly connected to the return water main pipe 2. Multiple drain pipes 15 are fixedly connected to the side of the return water branch pipe 16. The multiple drain pipes 15 are respectively connected to the drain outlets of multiple indoor heating pipelines 6.

[0029] In this embodiment, after the hot water is used in the indoor heating pipeline 6, the low-temperature water is introduced into the return water main pipe 2 through the drain pipe 15 and the return water branch pipe 16, and the water is centrally reheated by the return water main pipe 2.

[0030] For details, please refer to Figure 4 The input end of the pressure relief pump 9 is inclined and sleeved into the inner cavity of the inlet pipe 5. The inclination direction of the input end of the pressure relief pump 9 is the same as the direction of water flow in the inlet pipe 5.

[0031] In this embodiment, the high-pressure water in the inlet pipe 5 can be smoothly discharged from the pressure relief pump 9 and the pressure relief pipe 10 in order to complete the pressure relief of the inlet pipe 5.

[0032] For details, please refer to Figure 4 The output end of the booster pump 13 is inclinedly connected to the inner cavity of the inlet pipe 5, and the inclination direction of the output end of the booster pump 13 is the same as the water flow direction in the inlet pipe 5.

[0033] In this embodiment, it is ensured that the water pressurized by the booster pump 13 into the inlet pipe 5 mixes smoothly with the original water in the inlet pipe 5.

[0036] Working principle: When heating is supplied to a user's home, hot water first enters the heating branch pipe 4 from the main heating pipe 1. Simultaneously, the hot water in the heating branch pipe 4 enters the indoor heating pipeline 6 of the user's home from the inlet pipe 5. Used water is discharged from the drain pipe 15 and return branch pipe 16 into the return main pipe 2. The return main pipe 2 guides the low-temperature water back for reheating. While the water flows through the inlet pipe 5, the water pressure is monitored in real time by the water pressure monitor 11. When the water pressure is too high, the pressure relief pump 9 is activated, generating suction at its input end. A portion of the hot water in the inlet pipe 5 is removed to depressurize it. The hot water is then pumped back to the heating main pipe 1 via the pressure relief pipe 10 and the main pressure relief pipe 8 for use by subsequent users. When the water pressure monitor 11 detects that the water pressure in the inlet pipe 5 is too low, the booster pump 13 is activated to generate suction in the pumping pipe 14. The pumping pipe 14 is used to pump the hot water in the heating branch pipe 4 and pressurize it. The pressurized hot water mixes with the hot water in the inlet pipe 5 to ensure the hydraulic balance in the latter part of the inlet pipe 5.
