Referring to fig. 1, a hot water pipe system for locally controlling water circulation to achieve constant pressure discharge includes a water storage container 12, a main hot water pipe 15, a hot water circulation pipe 16, and three branch hot water pipes, wherein the water inlets of the branch hot water pipes are connected in parallel and then connected in series with the main hot water pipe 15; the water outlets of the branch hot water pipelines are connected with different downstream water using equipment.
The main hot water pipe 15 is connected to a hot water outlet of the water storage tank 12, the hot water circulation pipe 16 is communicated with the main hot water pipe 15, and the hot water circulation pipe 16 is connected to a hot water inlet of the water storage tank 12.
Wherein, the hot water circulation pipeline 16 is provided with an electric valve 9, and each branch hot water pipeline is provided with a branch valve. The first branch hot water pipeline 17 is provided with a first branch valve 6, the second branch hot water pipeline 18 is provided with a second branch valve 7, and the third branch hot water pipeline 19 is provided with a third branch valve 8. The flow of each branch hot water pipeline can be adjusted by adjusting the opening degree of each branch valve, and at least one branch hot water pipeline is determined to be a main water supply branch pipeline, such as the first branch hot water pipeline 17.
A plurality of pressure sensors are also included, wherein a main circuit pressure sensor 5 is provided in the main hot water pipe 15; and a branch pressure sensor is arranged in each branch hot water pipeline and is positioned at the water outlet side of the branch valve. The first branch hot water pipeline 17 is provided with a first branch pressure sensor 2, the second branch hot water pipeline 18 is provided with a second branch pressure sensor 3, and the third branch hot water pipeline 19 is provided with a third branch pressure sensor 4.
Each pressure sensor is electrically connected to a control device 1 (e.g., a central controller or other upper computer, or PC), and the control device 1 is electrically connected to the electrically operated valve 9 and each branch valve.
Preferably, a water pump 11 is further connected in series to the hot water circulation pipeline 16, and the electric valve 9 is located on a water outlet side of the water pump 11; and the water pump 11 is electrically connected with the control device 1.
Preferably, a heating device 13 is provided in the water storage container 12, and the heating device 13 is electrically connected to the control device 1. The temperature of the water in the water storage container 12 is adjusted by arranging the heating device 13, and the temperature of the outlet water is kept relatively stable. The heating device 13 may specifically use an electric heating wire to achieve heating.
The water storage device further comprises a cold water pipeline 14, the cold water pipeline 14 is connected with a cold water inlet of the water storage container 12, and the valve 10 is connected to the cold water pipeline 14 in series. The valve 10 may be an electrically controlled valve and is electrically connected to the control device 1.
Preferably, the bypass valve is provided adjacent to the junction of the bypass hot water pipe and the main hot water pipe 15. Thereby reducing the accumulated water of each branch hot water pipeline at the branch valve.
Preferably, the diameter of at least one branch hot water pipe is larger than the diameters of the other branch hot water pipes, as shown in fig. 2, the pipe diameters of the second branch hot water pipe 18 and the third branch hot water pipe 19 may be smaller than the pipe diameter of the first branch hot water pipe 17, so that the first branch hot water pipe 17 serves as a main water supply branch hot water pipe. The branch hot water pipes with smaller diameters, such as the second branch hot water pipe 18 and the third branch hot water pipe 19, can be used for connecting the small heat exchanger 22 because the water supply amount is relatively small, so as to recycle the heat in the pipes through the heat exchanger 22.

Preferably, the system further comprises a drain valve 20, which is connected in series with the upstream of the branch valve of each branch hot water pipeline, and is arranged at a height lower than that of each branch hot water pipeline, so as to drain a small amount of cooled accumulated water accumulated in the pipeline on the right side of the branch valve of each branch hot water pipeline.
When a branch pressure sensor on the branch hot water pipeline detects that the pressure in the corresponding pipeline is too high, a transmission signal is transmitted to the control device 1, and the control device 1 sends a signal to adjust a branch valve on the corresponding branch hot water pipeline so as to reduce the hot water flow of the branch hot water pipeline in a high-pressure state. Meanwhile, signals are sent to adjust the branch valve shunting of the hot water pipelines of other branches. When the branch pressure sensors of all branch hot water pipelines detect that the pressure is too high at the same time, the control device 1 sends a signal to adjust the branch valves on the branch hot water pipelines so as to reduce the hot water flow of the branch hot water pipelines in a high-pressure state, and sends a signal to open the electric valve 9 and the water pump 11 so that part of the water flow can flow back to the water storage container 12 through the hot water circulation pipeline 16. Further, the control device 1 will simultaneously send a signal to turn down the valve 10 on the cold water pipe 14 and reduce the power of the electric heating means 13 inside the water reservoir 12 when the hot water circulation pipe 16 is open. When the main pipe pressure sensor 5 on the main hot water pipe 15 detects that the main pipe pressure is too high, a signal is sent to the control device 1, and the hot water circulation pipe 16 is directly opened.
