Intelligent air valve, monitoring system and intelligent air valve monitoring method

Abstract

The invention provides an intelligent air valve. The intelligent air valve comprises a main valve, a valve part, an instant pressure sensor, a displacement sensor and a data recorder; the instant pressure sensor extends into the main valve, and is used for sensing instant fluid pressure in the main valve and capable of outputting pressure information; the displacement sensor is used for sensing the position change of the valve part and capable of outputting valve part displacement information; the instant pressure sensor and the displacement sensor are both connected with the data recorder; and the data recorder can record and transmit the pressure information and the displacement information into the processor. Known from working states of the intelligent air valve, when the intelligent air valve breaks down, failures can be timely discovered and processed to prevent engineering accidents. The invention further provides a monitoring system comprising the intelligent air valve. The monitoring system facilitates remote monitoring by workers. The invention further provides an intelligent air valve monitoring method; and the method facilitates detection and mastering of the working states of the intelligent air valve.

Description

technical field

[0001] The invention belongs to the technical field of valves, in particular to an intelligent air valve, a monitoring system and an intelligent air valve monitoring method. Background technique

[0002] The air valve is a valve used to ventilate the pipeline system and suppress the negative pressure caused by the transient process depressurization wave and its possible bridging water hammer. It is usually installed on the pipeline system to prevent the air resistance of the pipeline system during the process of transporting and distributing fluids. , collapse, pipe burst and equipment damage and other engineering accidents, so as to ensure normal liquid supply. However, the working state of the existing air valve is always unknown, and it is impossible to judge whether it is working normally; when the existing air valve fails, it cannot be found in time, especially in the transient process of the pipeline system, the performance of the air valve is completel...
