Description

Technical Field

[0001] The utility model relates to the technical field of heating pipe network operation, in particular to a multi-mode water replenishment control device for a heating pipe network. Background Art

[0002] During the operation of the heating network, the network pressure often fluctuates due to water loss, opening of new loads, etc., causing hydraulic imbalance in the entire heating system and seriously affecting the heating quality. Severe pressure fluctuations can cause the network to rupture or even cause the network to shut down. At this time, it is necessary to configure a suitable water replenishment system for the heating network to ensure that the network pressure fluctuation is within a certain range.

[0003] A multi-mode water replenishment control system for a heating pipe network is disclosed in a Chinese patent announcement with a search announcement number of CN214745989U, and its technical highlights are: it includes a water replenishment tank and a controller, the water replenishment tank is connected to at least three water replenishment pipelines in parallel through a water outlet pipeline, and the other end of the water replenishment pipeline is connected to the heating main network through a water replenishment main pipe; the water replenishment pipelines are all installed with water replenishment pumps, the water replenishment pumps are installed with water pump frequency converters, the water outlet pipelines are installed with ball valves, the water replenishment main pipes are installed with electric valves, flow meters and a first pressure transmitter, and the heating main network is installed with a second pressure transmitter; the electric valves, flow meters, first pressure transmitters, second pressure transmitters, and water pump frequency converters are all connected to the controller circuit.

[0004] In actual operation, it was found that the above scheme still has at least the following defects: although the device can replenish water to the heating network, it lacks temperature control equipment, which can easily lead to the temperature of the water added to the heating network being inconsistent with the temperature of the water in the original heating network. The water in the water supply pipe is cold in one section and hot in another, affecting its use. For this reason, we propose a multi-mode water replenishment control device for the heating network to solve the above problems. Utility Model Content
