Gas meter capable of automatically controlling gas pressure and preventing gas leakage

Abstract

The invention provides a gas meter capable of automatically controlling gas pressure and preventing gas leakage. The gas meter comprises a shell body, wherein the upper end of the shell body is provided with a gas inlet, a gas outlet, a gas inlet pipeline connected with the gas inlet, and a power supply module arranged at the inner part of the shell body; the top part of the shell body is provided with a gas detector, and an alarm device is arranged on the shell body; a gas pressure sensor is arranged on the inner wall of the gas inlet pipeline, and a self-closing valve is mounted on the gas inlet pipeline; the inner part of the shell body is provided with a processing module, and the processing module is respectively connected with the gas detector and the gas pressure sensor; the self-closing valve is connected with the gas pressure sensor, and the power supply module is respectively connected with the gas detector, the processing module, the self-closing valve, and the gas pressure sensor. The gas meter capable of automatically controlling gas pressure and preventing gas leakage is simple in structure, and can automatically control the gas pressure degree and send an alarm to prompt when gas is leaked; and thus the gas meter can be used to prevent the gas poisoning, fire disaster and other safety accidents.

Description

technical field [0001] The invention relates to a gas meter with automatic air pressure control and gas leakage prevention. Background technique [0002] The smart gas meter is mainly used to record the gas consumption, the gas charge pre-stored value is insufficient and the automatic alarm function, etc., does not have the function of automatic control of the air pressure and the alarm function of the gas leakage, and the gas pressure is often too low when the gas is used. People's use or high air pressure will affect the accuracy of the gas meter. At the same time, if the gas leakage is not found in time, the gas will spread rapidly, causing gas poisoning, fire and other safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to address the defects that the existing gas meter does not have automatic control of air pressure and prevention of rapid diffusion of gas after leakage, causing safety hazards such as gas p...
