Alarm device for remotely monitoring gas flow and pressure

Abstract

The invention discloses an alarm device for remotely monitoring gas flow and pressure, which comprises a gas supply pipeline. A plurality of gas supply branch pipes are communicated with the gas supply pipeline, and a first sensor group and a second sensor group are sequentially mounted at the joints of the gas supply branch pipes and the gas supply pipeline along the gas flow in the gas path communication direction of the gas supply pipeline; a third sensor group is mounted at the air outlet end of the air supply branch pipe; each of the first sensor group, the second sensor group and the third sensor group comprises a pressure sensor, a temperature sensor, a flow meter and a hazardous gas concentration sensor; the first sensor group, the second sensor group and the third sensor group are all in communication connection with an alarm. By arranging a plurality of sensor groups, pressure, flow, temperature, gas concentration and the like are detected, mutual detection of the pipeline and the sensors is realized, and the safety of the gas transportation pipeline is ensured.

Description

technical field [0001] The invention belongs to the field of alarms, in particular to an alarm device for remote monitoring of gas flow pressure. Background technique [0002] When transporting gas such as gas, it is necessary to monitor the pressure at all times to prevent gas leakage from causing danger and economic loss. However, the existing pressure detection is only to detect whether the air pressure exceeds the threshold value. Because there are many branch pipelines, gas will be used at any time, so after the air pressure drops, it is impossible to determine whether it is normal gas use or gas leakage. Improvements are therefore required. Contents of the invention [0003] In order to solve the above problems, the present invention discloses an alarm device for remote monitoring of gas flow pressure. The invention realizes the mutual detection of the pipeline and the sensor by setting multiple sets of sensor groups to detect the pressure, flow rate, temperature a...
