Cutting type diaphragm gas meter

Abstract

The invention discloses a cutting type diaphragm gas meter and belongs to a gas meter. The cutting type diaphragm gas meter comprises a base meter body, wherein a gas inlet and a gas outlet are arranged on the base meter body; a cutting valve is mounted at the gas inlet; the gas meter further comprises a signal acquisition treating circuit and a cutting type diaphragm gas meter terminal microcomputer controller; the signal acquisition treating circuit is connected with the cutting type diaphragm gas meter terminal microcomputer controller; the cutting valve is connected with the cutting type diaphragm gas meter terminal microcomputer controller through a cutting valve control circuit; the signal acquisition treating circuit is used for acquiring the flow of fuel gas flowing by the base meter body in real time and timely transmitting to the cutting type diaphragm gas meter terminal microcomputer controller; and when the abnormal states, such as small flow leakage, abnormal mass flow and over long service time, of the output of the base meter body are detected, the cutting valve on the base meter body is timely turned off and a liquid crystal display screen and a buzzer are utilized to alarm, so that the burning or explosion phenomenon caused by excessive leakage of the fuel gas is avoided and the life and property of people are protected.

Description

technical field [0001] The invention relates to a gas meter, more specifically, the invention mainly relates to a cut-off membrane gas meter. Background technique [0002] With the continuous improvement of the construction of gas projects in my country, the application range of gas has been greatly expanded, and a wider range of popularization has been achieved. However, there is no effective and reliable implementation method to deal with the abnormal state of the gas. When the gas is in an abnormal state during use, leakage, fire, explosion, etc. may occur, which is not conducive to the natural gas safety management of the gas company, and it is also harmful to people's lives and Property security brings great hidden dangers. [0003] Because the general diaphragm gas meter does not have the function of effectively collecting abnormal state information and pipeline safety cut-off, during use, when there are problems such as gas leakage of gas equipment and excessive gas co...
