specific Embodiment approach 1
[0036] Specific implementation mode one: refer to Figures 1 to 2 Specifically illustrate the present embodiment, the urban water supply pipe network pressure control mobile system described in the present embodiment, it comprises pressure regulating system, container truck 8, a No. 1 pressure sensor and No. 1 GPRS antenna,
[0037] The pressure regulating system is set inside the container truck 8, and the pressure regulating system includes a C valve 1, five manual butterfly valves 2, an industrial computer 6, a control cabinet 7, a pressure reducing pipeline 10, a bypass pipe 11, a booster pump 12 and a booster pump Pipeline 13, two No. 2 pressure sensors 4 and electromagnetic flowmeter 5,
[0038] The pipe sections at both ends of the decompression pipeline 10 pass through the container truck 8 and extend out of the car. The pipe sections at both ends are used to connect with the inlet pipe section of the pipe network in the test area. On the pressure pipeline 10, two No....
specific Embodiment approach 2
[0054] Specific embodiment 2: This embodiment is a further description of the urban water supply pipe network pressure control mobile system described in specific embodiment 1. In this embodiment, it also includes two air valves 3,
[0055] Both air valves 3 are arranged on the decompression pipeline 10,
[0056] Two air valves 3 are used to discharge excess air in the front and rear pipelines respectively,
[0057] The control cabinet 7 is also used to display the pressure difference between the front and rear pipelines and the flow data before and after pressure regulation.

Abstract
The invention provides a city water supply pipe network pressure regulation and control movable type system and a pipe network pressure regulation and control method achieved by adopting the system, and relates to the field of water supply pipe network pressure regulation and control study. The city water supply pipe network pressure regulation and control movable type system and the pipe network pressure regulation and control method achieved by adopting the system aim at solving the problem which exists in an existing mode that since a pressure increasing pump station or a pressure reducing station is installed to achieve pressure increasing or pressure reducing for a water supply pipe network, a pressure increasing pump or a pressure reducing valve needs to be installed at a fixed site, the pump or the valve cannot be moved after being installed, the space is wasted, and the pressure regulation and control mode is single. Pipe sections at the two ends of a pressure reducing pipeline penetrate through a container truck to extend to the portion outside the truck, the pipe sections at the two ends are used for being connected with an inlet pipe section of a testing area pipe network, and a control cabinet is used for receiving the pressure of the front pipeline and the rear pipeline to obtain a pressure difference and flow data before and after pressure regulation and control, and transmitting the data to a control plate card; pressure data of the most disadvantageous point is transmitted to the control plate card in a wireless mode through a first GPRS antenna on a first pressure sensor, and the control plate card is used for controlling the control cabinet to regulate and control the pressure of the testing area pipe network. The control plate card is used for regulating and controlling the pressure of the testing area pipe network.
Description
technical field [0001] The invention relates to a mobile system for regulating and controlling the pressure of an urban water supply pipe network and a method for regulating and controlling the pressure of the pipe network realized by the system, belonging to the research field of pressure regulating and controlling of the water supply pipe network. Background technique [0002] With the rapid development of social economy and the continuous reduction of water resources, the water supply industry pays more and more attention to the water supply efficiency of the pipe network. Due to the serious aging of my country's water supply pipe network, poor quality of pipe materials, abnormal operation and other problems, the pipe network has serious leakage, the pressure in some areas is not up to standard (difficult to meet the minimum service head), and the water supply efficiency is low. Due to the positive phase relationship between pressure and flow (leakage), the higher the pre...
