[0001] The utility model relates to the technical field of oil pipeline leakage prevention monitoring, in particular to a finished oil pipeline transportation leakage prevention monitoring device. Background Art

[0002] With the rapid economic development and technological advancement in various regions, the pipes of finished oil pipelines are generally steel pipes, which are connected into long-distance pipelines using connection devices such as welding and flanges, and valves are used for opening and closing control and flow regulation.

[0003] The above device does not have a structure for monitoring leakage at the connection end of the finished oil pipeline when in use. As a result, when the existing finished oil pipeline is in use, due to the high oil pressure in the pipeline and the corrosiveness of the oil in the pipeline to the sealing ring at the pipe connection, the connection end of the pipeline is very likely to leak after long-term use, causing losses, which may seriously cause fire or explosion. Leakage monitoring can mostly only monitor the value of the pressure change in the pipeline, and cannot accurately locate the leakage point. Based on the shortcomings of the existing technology, the utility model designs a leakage prevention monitoring device for finished oil pipeline transportation. Utility Model Content

[0013] As a preferred technical solution of the present invention, the movable cover of the dust cover is connected to the outside of the pressure relief valve.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. A leak-proof monitoring device for transporting refined oil in a pipeline, wherein the first sealing strip and the second sealing strip are respectively placed in the interior of the first sealing groove and the second sealing groove, and then the first sealing cover and the second sealing cover are respectively covered on the connecting ends of the first oil pipe and the second oil pipe from the upper and lower sides thereof, and the first sealing cover and the second sealing cover are connected and fixed by the second sealing strip to achieve sealing. At this time, the warning column and the sealing ring are at the bottom of the inner cavity of the monitoring cylinder. When leakage occurs at the connection between the first flange and the second flange, the pressure in the first sealing cover and the second sealing cover increases. Since the monitoring cylinder is connected with the inner cavity of the first sealing cover through the connecting hole and the through hole, the inner cavity of the first sealing cover and the second sealing cover increases, and the warning column and the sealing ring are lifted up. If the leakage state is more serious, the warning column and the sealing ring continue to move upward until the warning column can be directly observed at the observation window.

[0016] 2. This device for monitoring the leakage of refined oil pipeline transportation can effectively prevent wind, sand, and dust from entering the pressure relief hole of the pressure relief valve by covering the dust cover on the pressure relief valve in a normal state. If a leak occurs at the connection end between the first oil pipe and the first sealing cover, causing the warning column and the sealing ring to move upward, the upward-moving warning column can push the push seat and the connecting rod to move upward and pull the dust cover off the pressure relief valve. When the leakage pressure is too high and the warning column moves above the pressure relief valve, the inner cavity of the monitoring tube is connected to the outside through the pressure relief valve for continuous pressure relief, and the warning column is always at the observation window for warning. This device is convenient for protecting the pressure relief valve or for emergency pressure relief. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Working principle: When a leak-proof monitoring device for transporting refined oil pipelines is used, in the initial state, first, the first oil pipe 1 and the second oil pipe 102 are respectively provided with a first flange 101 and a second flange 103 at the opposite ends, and a gasket 104 is placed between the first flange 101 and the second flange 103, and the first bolt 105 is used to connect the first oil pipe 1 and the second oil pipe 102 so as to facilitate the connection of the first oil pipe 1 and the second oil pipe 102 for oil transportation. A first sealing strip 204 and a second sealing strip 202 are connected between the first sealing cover 2 and the second sealing cover 202 connected to the outer side of the connection between the first oil pipe 1 and the second oil pipe 102. 5, and the first sealing strip 204 and the second sealing strip 205 are in contact with the side walls of the first oil pipe 1 and the second oil pipe 102, so as to facilitate the sealing connection between the first sealing cover 2, the second sealing cover 202, the first oil pipe 1 and the second oil pipe 102. At the same time, the fixed base plate 301 connected to the top of the first sealing cover 2 and the monitoring tube 302 are sealed and slidably connected with the warning column 306 and the sealing ring 307, and the through hole 305 opened at the bottom of the fixed base plate 301 is in communication with the inner cavity of the connecting hole 311 opened at the top of the first sealing cover 2, so as to facilitate the monitoring of leakage at the connecting end of the first oil pipe 1 and the second oil pipe 102;

[0030] When it is necessary to monitor whether there is leakage between the first oil pipe 1 and the second oil pipe 102, firstly, the first sealing strip 204 and the second sealing strip 205 are respectively placed in the first sealing groove 201 and the second sealing groove 203, and then the first sealing cover 2 and the second sealing cover 202 are respectively covered on the connecting ends of the first oil pipe 1 and the second oil pipe 102 from the upper and lower sides thereof, and the first sealing cover 2 and the second sealing cover 202 are connected and fixed by the second sealing strip 205 to achieve sealing. At this time, the warning column 306 and the sealing ring 307 are at the bottom of the inner cavity of the monitoring tube 302. When the first flange 101 When leakage occurs at the connection between the first and second flanges 103, the pressure inside the first sealing cover 2 and the second sealing cover 202 increases. Since the monitoring tube 302 is connected to the inner cavity of the first sealing cover 2 through the connecting hole 311 and the through hole 305, the inner cavity of the first and second sealing covers 202 increases and the warning column 306 and the sealing ring 307 are lifted up.
