Scanning type pipeline leakage detecting mechanism

Abstract

The invention discloses a scanning pipeline leakage detection mechanism, which comprises a base, a pipeline, two sealing mechanisms symmetrically arranged along the pipeline, a connecting pipe, a pressure gauge, a servo motor, a lead screw, a feed nut, and a sliding seat , a support frame, the sealing mechanism also includes a sealing seat, a number of not less than 3 sealing rings uniformly distributed along the sealing seat, a sealing rubber ring, a retaining ring, a steel ball, a rubber sleeve, a first inlet The air passage, the second air inlet passage, the plug, the servo motor drives the connecting pipe to move, and scans the pipe for inspection. When the pressure detected by the pressure gauge exceeds the set value, the servo motor stops and the leaking part is sealed. The device has a simple structure. Through scanning detection, it can perform real-time detection on the entire pipeline to improve safety performance. It adopts a floating design and uses three-stage sealing to effectively prevent the leakage of gas from being discharged, so that the leaked gas is filled with the connecting pipe, which effectively improves 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.
