Description

technical field [0001] The invention relates to the technical field of pipeline systems, in particular to a gas pipeline metering and pressure regulating device and method. Background technique [0002] In the gas pipeline station, in order to meet the normal operation of the pipeline, it is necessary to detect and control the flow and pressure of the gas transported by the pipeline. In the past, there are two main process methods: Method 1, the metering system and the pressure regulating system are respectively set up, and the two systems are relatively independent. Among them, the metering system mainly includes the front and rear gas collection pipes, the upstream and downstream straight pipe sections, the upstream and downstream shut-off valves and the flow rate. The pressure regulating system mainly includes the front and rear gas manifolds, upstream and downstream cut-off valves and regulating valves, and uploads the data of the metering system and pressure regulating ...
