Embodiment Construction

[0046] The present invention will be further described below in conjunction with the examples.

[0047] Such as figure 1 As shown, when the municipal gas pipeline supplies gas to users, decompression treatment is required. The decompression system mainly includes a pressure regulating valve and a relief valve. ratio of gas to air).

[0048] A pressure transmitter is installed on the low-pressure pipeline between the pressure regulating valve and the gas equipment, which is used to collect the pressure on the low-pressure gas pipeline in real time, and is used to realize the judgment of the state of the downstream valve port, the monitoring of the flow rate behind the pressure regulating valve, and correlation The combined meter has the monitoring of measurement accuracy and timely detection of gas theft.

[0049] Such as figure 2 As shown, by monitoring the characteristic flow rate behind the valve port of the pressure regulating valve, the state of the valve port of the p...

Abstract

The invention provides a method for monitoring characteristic flow of a low-pressure gas pipeline. The method is characterized in that a pressure regulating device is arranged, the two sides of the pressure regulating device are respectively connected with the low-pressure gas pipeline and a medium-pressure gas pipeline, the pressure regulating device is connected with gas utilization equipment through the low-pressure gas pipeline, a pressure transmitter is arranged on the low-pressure gas pipeline, and the pressure transmitter is used for collecting real-time pressure in the low-pressure gas pipeline, establishing a p-t curve of pressure and time, obtaining the slope k of the p-t curve by continuously calculating the pressure variation delta p within delta t time, and judging the state of the pressure regulating device and the change of the flow in the low-pressure gas pipeline according to the slope k. The technical problems that an existing low-pressure gas pipeline monitoring manner mainly adopts a manual inspection manner, a large amount of manpower and time need to be consumed, cost is high, the inspection frequency is lower, and safety and reliability are poor are solved. The method can be widely applied to low-pressure gas pipeline monitoring.

Description

technical field [0001] The invention relates to a flow monitoring method, in particular to a method for monitoring the characteristic flow of a low-pressure gas pipeline. Background technique [0002] Natural gas is one of the most important clean energy sources for human beings. With the increase of proven reserves and the improvement of mining technology, the use of natural gas is becoming more and more popular. At present, the monitoring of downstream gas pipeline network mainly adopts the method of manual inspection. For the monitoring of downstream low-pressure pipeline network with many branch pipelines, it needs a lot of manpower and time, and the cost is high. The frequency of inspection is low, which is safe and reliable. Poor sex. Contents of the invention [0003] The present invention aims at the technical problems that the existing downstream low-pressure gas pipeline network monitoring mainly adopts manual inspection, which requires a lot of manpower and tim...
