Abstract

The invention relates to a detecting system used for the leakage of a gas valve, which mainly utilizes the arrangement of a wireless sensor network. The detecting system provided by the invention comprises a wireless pressure transmitter, a bonding wireless temperature transmitter and a wireless ultrasonic leakage sensor, wherein the wireless pressure transmitter and the bonding wireless temperature transmitter are installed on the front and rear pipelines of the gas valve; the wireless ultrasonic leakage sensor is installed at the lateral side of the valve, thereby uploading signals with little change in pressure and temperature passing the front and rear section of the valve and ultrasonic leakage signals obtained by the wireless ultrasonic leakage sensor to a wireless gateway; the gateway is communicated with a computer through a wire mode; and the analysis software of the computer comprehensively utilizes a pressure distributing method, a temperature detecting method and an ultrasonic leakage detecting method to analyze the leakage of the valve, and analyzes and judges the leakage conditions of the valve through data. The detecting system provided by the invention has the advantages that the adopted methods have higher accuracy and sensitivity and the wireless transmitters are convenient and rapid to install, does not need to additionally lay a signal cable, can repair the leakage in time and has great significance on enhancing the production efficiency of enterprises and saving energy sources.

Description

technical field [0001] The invention relates to a detection technology, in particular to a detection system for gas valve leakage. Background technique [0002] At present, pipelines for storing and transporting compressed gas are widely used in industry and life, and the connection and control of gas movement in these pipelines are composed of various valves, such as for oil and natural gas collection, oil refining, Pressure relief valves, isolation valves and bypass valves on various pipelines and oil storage tanks and gas storage tanks in petrochemical, chemical and other industries, as well as steam traps in steam pipelines in factories, etc. Valves are the core actuators in the automatic control system and safety protection system of the petrochemical industry, and are called the "throat" of the petrochemical industry. The performance and status of valves will not only affect the quality and safety of the petrochemical industry production process, but also have a great...
