Scanning type pipeline leakage detecting mechanism

Abstract

The invention discloses a scanning type pipeline leakage detecting mechanism which comprises a base, a pipeline, two sealing mechanisms symmetrically arranged along the pipeline, a connecting pipe, a pressure gage, a servo motor, a lead screw, a feeding nut, a sliding seat and a supporting frame; each of the sealing mechanisms comprises a sealing seat, sealing rings, a sealing rubber ring, a check ring, a steel ball, a rubber sleeve, a first air inlet passage, a second air inlet passage and an end cap, wherein the sealing rings are uniformly distributed along the sealing seat and are more than 3; the servo motor works to drive the connecting pipe to move, so that scanning type detection is carried out on the pipeline; and when the pressure detected by the pressure gage exceeds a set value, the servo motor stops, and the leaked part is sealed. The scanning type pipeline leakage detecting mechanism is simple in structure, detects the whole pipeline in real time through scanning type detection to improve the safety performance, and adopts a floating design to effectively prevent the leaked gas from emission through three stages of sealing so as to enable the leaked gas to be full of the connecting pipe and to effectively improve the detection precision.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a scanning pipeline leakage detection mechanism. Background technique [0002] The pipeline is a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. In the field of hazardous gas production and transmission applications, the pipeline needs to be completely sealed. If a leak occurs, it may cause In major safety accidents, in the high-pressure main pipeline, due to the high gas pressure and fast flow rate, the gas flow rate in the pipeline exceeds a certain range, which will generate scour force, damage the pipeline wall, and eventually cause perforation, resulting in leakage. At the same time, gas corrosion It also further accelerates the perforation of the pipeline wall. Since there is a certain lag in the manual use of instruments to detect gas leakage, it is difficult to detect the leakage immediately after the leakage occurs, resu...

[0002] The pipeline is a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. In the field of hazardous gas production and transmission applications, the pipeline needs to be completely sealed. If a leak occurs, it may cause In major safety accidents, in the high-pressure main pipeline, due to the high gas pressure and fast flow rate, the gas flow rate in the pipeline exceeds a certain range, which will generate scour force, damage the pipeline wall, and eventually cause perforation, resulting in leakage. At the same time, gas corrosion It also further accelerates the perforation of the pipeline wall. Since the manual use of instruments to detect gas leakage has a certain lag, it is difficult to detect the leakage immediately after the leakage occurs, resulting in a large amount of dangerous gas being discharged outside the site, which poses a great safety hazard.
