Intelligent pressure control system

Abstract

The invention discloses an intelligent pressure control system. The intelligent pressure control system comprises a pressure reducing valve, a controller, a pressure reducing guide valve, a decompression guide valve and an electromagnetic valve group, wherein a pressure transmitter electrically connected with the controller is arranged at each of two ends of the pressure reducing valve; the electromagnetic valve group is electrically connected with the controller and comprises a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve and a fourth electromagnetic valve; and the controller comprises a single chip microcomputer, a relay, a storage module, a clock module, a power supply module, a key, a display module and a GPRS communication module which areconnected. The intelligent pressure control system is high in automation degree, adjustment precision and response speed and can be used for monitoring pressure information of a pipe network in realtime and remotely maintaining a pipe network pressure system without manual intervention, so that the dynamic stability of the pipe network pressure is maintained, sudden leakage loss and tube bursting frequency can be maximally reduced, the management and maintenance levels of the pipe net are increased to a great extent, and the safe and stable operation capacity of the pipe network is improved.

Description

technical field [0001] The invention relates to a pressure control device for a pipe network, in particular to an intelligent pressure control system. Background technique [0002] The pressure management of urban water supply pipe network is a simple and effective way to reduce the leakage of pipe network and reduce the frequency of pipe burst. At present, the use of pressure reducing valves to regulate pressure in independent metering zones with closed boundaries is a relatively common pressure management measure. In the absence of power supply, the hydraulically driven pressure reducing pilot valve is currently the most common solution. [0003] However, this solution has some shortcomings: on the one hand, the existing pressure reducing pilot valve can keep the pressure behind the valve at a stable value, but the pilot valve on the pressure reducing valve needs to be manually adjusted, and there is insufficient automation of pressure adjustment, and the response On the...
