Marker post convenient for detecting and positioning gas leakage point

Abstract

The invention discloses a marker post convenient for detecting and positioning a gas leakage point, and relates to the field of gas pipeline marker posts. The marker post aims at solving the problemsthat an existing gas pipeline is inconvenient to carry out leakage alignment, the positioning is troublesome and not accurate enough, meanwhile, the detection operation is low in efficiency, the coverage range is small, the self-protection performance of a detection device is poor, and gas guide is inconvenient. According to the scheme, the marker post comprises a gas pipeline, a semicircular hollow pipe is arranged on the upper side of the gas pipeline, the upper end of the semicircular hollow pipe is fixedly connected with an eduction tube, the upper end of the eduction tube is connected with a first marker post and a second marker post, and the left side and the right side of the second marker post are connected with gas guide openings. The marker post has the advantages that the detection coverage range is greatly improved, the leakage point section can be effectively and timely detected, the positioning accuracy is greatly improved, meanwhile, the marker posts arranged at intervals are effectively utilized, and the leakage gas can be exported in time.

Description

technical field [0001] The invention relates to the field of gas pipeline marking piles, in particular to a marking pile for convenient detection and positioning of gas leakage points. Background technique [0002] Natural gas pipelines refer to pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas pipelines. The use of natural gas pipelines to transport natural gas is a way to transport large quantities of natural gas on land. Natural gas pipelines account for about half of the world's total pipeline length. [0003] Since the buried gas pipeline leaks, it has always been a problem to find the leak point at the first time, which has troubled us. Therefore, we want to make a systematic improvement in equipment and project implementation, so as to solve this problem. . [0004] In addition, the detection of the existing...
