Description

Technical Field

[0001] The utility model relates to the technical field of heating pipe networks, and more specifically to a water distribution and collection device for a heating pipe network. Background Art

[0002] The urban central heating pipeline network is a pipeline system that transports and distributes heating media from the urban central heating source to the heat users. The heat network consists of heat transmission trunk lines, heat distribution trunk lines, and branches. The heat transmission trunk lines are drawn from the heat source, and the heat distribution trunk lines are connected from the heat transmission trunk lines or directly from the heat source, and supply heat to users through the heat distribution branch lines.

[0003] At present, the uniformity of heat flow distribution of the heating medium is generally improved by optimizing the network pipe structure through reasonable matching of pipe diameters. However, there is still a large temperature difference between the room temperatures of two communities that are far apart during the heating season, and the heating effect is not ideal, which still makes it difficult to meet the actual needs of heat users.

[0004] After searching, a Chinese patent with authorization announcement number CN220793242U discloses a heating pipe network water distribution and collection device and a heating pipe network. The structure connects a number of branch pipes connected to the areas to be heated on the main pipe, so as to connect the heating medium of the heating station to multiple areas to be heated with different distances and water consumption through the branch pipes. Then, the heat flow in the corresponding branch pipes is monitored according to the monitoring device, and the control valve on the corresponding branch pipe is controlled to adjust the heating medium in the pipe to ensure that the heat flow of each area to be heated meets the load requirements. The flow of the heating medium in each branch pipe can be effectively and reasonably controlled to evenly distribute the heat flow and improve the heating efficiency and effect.

[0005] However, when this structure is actually used, the heating medium is transported through the first branch into the area to be heated for heat exchange, causing heat loss during the transportation process, and the heat exchange efficiency is affected due to the small heat exchange area.

[0015] Technical effects and advantages of the utility model:

[0016] 1. By setting up a heat exchange mechanism, compared with the prior art, the branch water pipe transports water to the inside of the L-shaped pipe, and then enters the heat exchange tube through the L-shaped pipe for heating.

With the flow of hot water, the heat is gradually released to the heating area, and the cooled water is discharged through the output pipe to form a cycle, reduce heat loss, and control the size of the delivery flow to ensure the balance of water in each branch water pipe;

[0017] 2. By setting up a disassembly mechanism, compared with the prior art, the bolts on one side of the first flange are rotated to separate the first flange from the second flange, thereby removing the L-shaped pipe, and then the inside of the branch pipe can be cleaned. Secondly, the sealing effect is also enhanced by the sealing ring to prevent water leakage. When the surface of the fixed disk is severely worn, the fixed disk is rotated clockwise, thereby driving the threaded barrel to rotate clockwise to remove the threaded barrel from the threaded rod, thereby replacing the fixed disk. In addition, the direction in which the motor drives the threaded rod to rotate is counterclockwise, so that the threaded barrel will not fall off, thereby ensuring safe use.
