Embodiment Construction
[0025] Build the main circuit of the straight pipe leakage characteristic experiment system, and conduct the straight pipe leakage characteristic experiment according to the following steps:
[0026] 1. Place the buckle 13 of a certain aperture in the leakage port A of the straight pipe 14, and press it to death with the top pressure elbow 28;
[0027] 2), the leakage circuit of the straight pipe leakage characteristic experiment system is connected, and the water supply pump 3, the water outlet mass flowmeter 9 and the leakage outlet mass flowmeter 27 are powered on;
[0028] 3) Start the water pump 3, adjust the pressure regulating valve 7, observe the readings of the pressure gauge I15 and pressure gauge II16 until the set pressure. After a period of time, start to record the indication value of the mass flow meter 27 at the leak port, and record it once every other period of time;
[0029] 4) Adjust the pressure regulating valve 7 to stabilize the system at other pressure...

The invention discloses an experimental method for leakage characteristics of a buried petroleum transmission pipeline and belongs to the field of leakage characteristic research of the buried petroleum transmission pipelines. An experimental system for the leakage characteristics of the buried petroleum transmission pipeline, which is used by the method, can be used for researching the leakage characteristics of a straight pipe, an elbow, a tee joint, a flange and a valve. For the straight pipe, the elbow and the tee joint, the experimental system is used for researching the leakage characteristics of orifices; for the flange, the experimental system is used for researching the leakage characteristic of the flange when a pretightening force of a bolt is insufficient; for the valve, the experimental system is used for researching the internal leakage characteristic of the valve. The experimental system is formed by connecting the flanges, is convenient to dismount and mount, can be used for researching the leakage characteristics of various parts (the straight pipe, the elbow, the tee joint, the flange and the valve) and can be widely applied to laboratory investigation of colleges and universities and scientific research institutions and preliminary study of relevant enterprises.
Description
technical field [0001] The invention belongs to the field of research on leakage characteristics of buried oil pipelines, and in particular relates to an experimental method for leakage characteristics of buried oil pipelines. Background technique [0002] Corrosion and perforation of pipelines, sudden natural disasters (such as earthquakes, landslides, river scouring) and man-made sabotage will cause pipeline leakage or rupture, threatening the safe operation of buried oil pipelines. Since the leakage rate is affected by many factors such as soil gravity, oil body temperature, shape and size of the leakage port, and the special environment in which it is difficult to conduct field experiments, it is very necessary to establish an experimental system for the leakage characteristics of buried oil pipelines. At present, the experimental systems for the leakage characteristics of buried oil pipelines at home and abroad can only conduct experimental research on the leakage chara...
