Pipe network pressure control circuit and system

Abstract

The invention relates to a pipe network pressure control circuit. A control module, a pressure detection module, a communication module and a driving module are additionally arranged to control the adjusting process and the pressure precision, and the control module controls the driving module according to a pipe network actual pressure value obtained from the pressure detection module or data ofa digital flow meter from the communication module, so that pipe network pressure changes are obtained in real time to adjust the pipe network pressure; and low-energy-consumption management is achieved by additionally arranging a power management module, downstream pressure changes are obtained in real time by additionally arranging a pressure detection module and the driving module to then adjust the pipe network pressure, the problem that due to the fact that the downstream pressure is too large, a pipeline is exploded or water does not exist due to too low pressure is avoided, and the problems that according to a traditional technical scheme, manpower is consumed, the adjusting process and the pressure precision are difficult to control, the pressure of the downstream pipeline cannot be adjusted in real time according to the changes of downstream pressure requirements, and energy consumption waste is caused due to the fact that a power source cannot be managed in a centralized modeare solved.

Description

technical field [0001] The invention belongs to the technical field of control, and in particular relates to a pipe network pressure control circuit and system. Background technique [0002] At present, the traditional pipe network pressure control management is mainly realized by adjusting the outlet pressure of the pressure reducing valves distributed in the water pipe network. There are two adjustment methods: [0003] One is manual adjustment, which meets the requirements of the water pipe network by manually adjusting the pressure reducing valve, but the manual adjustment method requires personnel to be on duty, and the adjustment process and pressure accuracy are difficult to control; [0004] The other is timing adjustment, which adjusts the pressure of the pipe network by preset fixed time and pressure, but the timing adjustment method cannot adjust the pressure of the downstream pipeline in real time as the downstream pressure demand changes, causing the downstream ...
