[0027] Please see Figures 1-3This utility model discloses a pipeline pressure device for water supply and drainage scheduling, including a pipeline body 1, a pressure detection component and a regulating component;

[0028] The pressure detection component is installed on the main body of the pipeline network 1 and is used to detect the pressure inside the main body of the pipeline network. The inner wall of the main body of the pipeline network 1 is provided with an anti-corrosion layer, which is a polytetrafluoroethylene coating. The outer wall of the main body of the pipeline network 1 is provided with an insulation layer, which is a polyurethane foam layer. The polyurethane foam insulation layer on the outer wall can reduce the loss of water temperature inside the pipeline, and is especially suitable for cold regions to avoid the pipeline freezing and cracking due to low temperature.

[0029] The regulating component is connected to the main body of the pipeline network 1 and is used to regulate the pressure inside the main body of the pipeline network;

[0030] The pressure detection component includes at least two pressure sensors 2, which are spaced apart along the length of the main body of the pipeline network 1. The pressure sensors can comprehensively capture pressure data of different sections of the pipeline network, avoid missing local pressure anomalies at a single detection point, and provide accurate data support for subsequent pressure regulation.

[0031] In this invention, the regulating component includes a booster pump 3 and a pressure reducing valve 4. The inlet of the booster pump 3 is connected to an external water source, and the outlet of the booster pump 3 is connected to the inlet of the main pipe network 1 via a pipe 5. The pressure reducing valve 4 is installed on the outlet pipe 6 of the main pipe network 1, and the pressure reducing valve 4 is detachably connected to the pipe of the main pipe network 1. When the pressure sensor detects that the pipe network pressure is lower than 0.3 MPa, the booster pump can be started to increase the pressure. When the pipe network pressure is higher than 1.2 MPa, the pressure reducing valve automatically opens to release pressure, ensuring that the pipe network pressure is stable within the safe range of 0.3-1.2 MPa.

[0032] This utility model also includes a buffer assembly; the buffer assembly includes a buffer tank 7 and an elastic diaphragm 8, the buffer tank 7 is connected to the middle pipe of the main body of the pipeline network 1 through a branch pipe 9; the elastic diaphragm 8 is disposed inside the buffer tank 7, dividing the interior of the buffer tank 7 into an air chamber 10 and a water chamber 11, the water chamber 11 is connected to the branch pipe 9, and the air chamber 10 is filled with compressed nitrogen; the top of the buffer tank 7 is provided with a pressure regulating valve 12, which is connected to the air chamber 10 and is used to regulate the nitrogen pressure in the air chamber; the bottom of the buffer tank 7 is provided with a drain valve 13, which is connected to the water chamber 11 and is a manual shut-off valve. When the water flow velocity in the pipeline changes suddenly and causes an impact, the water flows into the water chamber and squeezes the elastic diaphragm. The compressed nitrogen in the air chamber absorbs the impact force through elastic deformation, thus mitigating the impact of the water flow on the inner wall of the pipeline and the joints. The air pressure regulating valve at the top of the buffer tank can adjust the air chamber pressure according to actual needs, and the drain valve at the bottom can periodically discharge a small amount of impurities deposited in the water chamber, ensuring the stable operation of the buffer assembly.

[0033] This utility model also includes a filter assembly; the filter assembly includes a filter cylinder 14 and a filter screen 15; the filter cylinder 14 is installed on the water inlet pipe of the main body of the pipe network 1, and the filter cylinder 15 is connected to the pipe of the main body of the pipe network 1 through a flange; the filter screen 15 is disposed inside the filter cylinder 14. This filter assembly can effectively intercept sand and impurities in the water, preventing impurities from entering the pipe network and clogging the pipes or damaging the regulating components. The stainless steel material has the characteristics of rust resistance and high strength, and can be used for a long time without frequent replacement.

[0034] Working Principle: During operation, the device first filters the water through a filter assembly at the inlet of the main pipeline network. The filter screen inside the filter cylinder intercepts sand and impurities in the water, preventing blockages or damage to downstream components and ensuring clean water flow. At least two pressure sensors, spaced apart along the length of the main pipeline network, monitor the pressure in different sections of the network in real time, providing data support for adjustment. When the sensor detects that the network pressure is lower than the set value, the booster pump starts, drawing water from an external source, pressurizing it, and then delivering it to the main pipeline network to increase the internal pressure. If the pressure is higher than the set value, the pressure-reducing valve at the outlet of the network automatically opens to release pressure, ensuring the pressure remains stable within a safe range. The buffer assembly in the middle of the network works simultaneously. When water flows, some water enters the buffer tank's water chamber, compressing the elastic diaphragm. Compressed nitrogen in the air chamber absorbs the impact force through elastic deformation, reducing damage to pipes and joints. The air chamber pressure can be adjusted via the top pressure regulating valve, and the bottom drain valve of the buffer tank periodically removes deposited impurities, ensuring long-term stable operation of the device. Simultaneously, the inner anti-corrosion layer and outer insulation layer of the pipeline network serve to prevent corrosion and maintain water temperature, respectively.

[0035] In summary, this utility model has a novel structural design, which can achieve accurate detection and stable regulation of water supply and drainage network pressure, while reducing the damage to the pipeline caused by water flow impact, preventing impurities from clogging the pipeline, and ensuring the efficient operation of the water supply and drainage system.

[0036] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
