Problems solved by technology

[0002] In order to ensure the safety of water supply on long-distance water pipelines, air valves need to be installed at local high points, slope change sections, and long-distance straight sections of the pipeline to automatically exhaust or enter water according to the situation of pipeline water filling or drainage. Air, the number of air valves installed on long-distance water pipelines is quite large. At present, all kinds of air valves lack automatic monitoring devices for their working status. Network water hammer, even pipe burst and pipe collapse accidents; if you only rely on manual inspection of the pipeline to check whether the air valves are working normally, it is time-consuming, laborious and inefficient

Abstract

The invention provides an air valve state monitoring device and method. By arranging the air valve monitoring device, different work states of air discharge, suction, sealing, failure and the like ofair valves on a pipeline or a pipe network can be remotely monitored by a center control unit, if failure happens, the position of a faulty air valve can be displayed in the center control unit, and an alarm is sent out, so that a manager can maintain and overhaul the air valve in time, the manual patrolling work-load is reduced, the service life of the air valve is prolonged, bad accidents, suchas pipe network water hammer, pipe explosion and pipe collapse, are prevented, and smart water management can be easily improved.

Description

technical field [0001] The present invention relates to the technical field of air valves, and more specifically, to an air valve state monitoring device and method. Background technique [0002] In order to ensure the safety of water supply on long-distance water pipelines, air valves need to be installed at local high points, slope change sections, and long-distance straight sections of the pipeline to automatically exhaust or enter water according to the situation of pipeline water filling or drainage. Air, the number of air valves installed on long-distance water pipelines is quite large. At present, all kinds of air valves lack automatic monitoring devices for their working status. Network water hammer, and even pipe burst and pipe collapse accidents; if only rely on manual inspection of the pipeline to check whether the air valves are working normally, it is time-consuming, laborious and inefficient. Contents of the invention [0003] The technical problem to be sol...
