Description

Technical Field

[0001] This utility model belongs to the field of heating network technology, and more specifically, it relates to a heating network temperature balance regulation device. Background Technology

[0002] A heating network is a part of the infrastructure used in a centralized heating system. It transmits heat (usually hot water or steam) from heat sources (such as boilers or heating stations) to various heat-consuming units or buildings through a series of pipes to provide heating and domestic hot water. The heating network is one of the core components of a centralized heating system, ensuring that heat energy can be delivered to users efficiently and safely.

[0003] Some current heating networks control the network temperature by combining hot and cold water during the water delivery process. This can easily lead to unstable temperatures and large temperature differences during the combination of hot and cold water.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a heating network temperature balance regulation device in order to achieve a more practical purpose. Utility Model Content

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides a temperature balancing and regulating device for a heating network, including a main pipe 1 connected to the entire heating network. A secondary pipe 2 is installed at the top of the main pipe 1 and is connected to the main pipe 1. A buffer tank 3 is installed at the top of the secondary pipe 2. A hot water pipe 4 is installed on one side of the buffer tank 3, and a cold water pipe 5 is installed on the other side of the buffer tank 3, so that the cold and hot water can be mixed in advance during the process of entering, reducing the occurrence of uneven temperature. A stirring rod 6 is rotatably installed at the top of the buffer tank 3 through a bearing seat. A temperature sensor 7 is installed inside the buffer tank 3, and the temperature sensor 7 is connected to the control system of the entire heating network to monitor the temperature inside the buffer tank 3 in real time.

[0024] The buffer tank 3 is equipped with a motor 8 at its top, and the output end of the motor 8 is connected to the stirring rod 6 via a coupling. The motor 8 drives the stirring rod 6 to rotate, thereby improving the mixing effect of cold water and hot water.

[0025] The secondary pipe 2 is equipped with a first control valve 9, which facilitates the control of the opening and closing of the secondary pipe 2.

[0026] A second control valve 10 is installed on one side of the main pipeline 1 to facilitate the control of the opening and closing of the main pipeline 1.

[0027] An impeller 11 is installed on the other side of the main pipe 1 to further enhance the mixing of water flow within the main pipe 1.

[0028] The working principle of this embodiment is as follows: When using the heating network temperature balancing regulating device, the operator first connects the device to the heating network and connects the hot water pipe 4 and the cold water pipe 5 to the hot water supply device and the cold water supply device, respectively. After installation, when the heating network control system issues a water supply command, the hot water supply device and the cold water supply device respectively input a fixed amount of hot water and cold water into the buffer tank 3. At the same time, the motor 8 turns on to mix the hot water and cold water, thereby reducing the occurrence of temperature unevenness. When the water flows through the impeller 11, the water flow pushes the impeller 11 to rotate, thereby further improving the mixing effect. During the use of the device, the first control valve 9 is in the open state and the second control valve 10 is in the closed state. When multiple sets of this balancing regulating device are in use, the second control valve 10 is in the open state. According to the water supply demand of the heating network, the second control valve 10 is opened at the corresponding position, thereby realizing the long-distance transportation of water.
