Description

Technical Field

[0001] This utility model relates to the field of fluid transport pipeline cleaning technology, specifically a jet pig with a rifling structure for the perforation. Background Technology

[0002] The main mode of transportation for oil, gas, and natural gas is pipeline transportation. During pipeline transportation, due to factors such as the pipeline's operating years, pipeline length, and the wax content of the oil, paraffin or other impurities may accumulate on the inner wall of the pipeline, which can easily cause blockages or even complete blockages. Regular cleaning and dredging of the pipeline are necessary.

[0003] Existing jet pigs typically employ a method of adding baffles at the front end to enhance their purging capacity. However, this design increases the weight of the jet pig itself, which can easily cause it to get stuck and exacerbate wear between the jet pig and the inner wall of the pipeline, affecting the pipeline's transport efficiency and safety.

[0010] Beneficial effects: By setting through holes of different diameters in the first and second sealing discs, this utility model can increase the flow rate and velocity of the fluid medium entering from the second through hole and exiting from the first through hole, thereby enhancing the purging capability of the jet pig.

[0011] Preferably, a positioning device is provided at one end of the perforation hole.

[0012] Preferably, the positioning device is a magnetic induction ring, and the magnetic induction ring is gear-shaped.

[0013] Beneficial effects: This utility model fixes the positioning device at the end of the perforation, which not only does not affect the passage of fluid medium through the perforation, but also monitors the position of the jet pig, preventing the jet pig from being lost in the pipeline and causing pipeline blockage.

[0014] Preferably, the first sealing disc and the second sealing disc are symmetrically fitted at both ends of the body.

[0015] Preferably, a first fixing plate and a second fixing plate are respectively provided at both ends of the main body.

[0027] according to Figure 1-4 As shown, this embodiment provides a jet pig with a rifling structure for the perforations, including a body 10. The body 10 has perforations 11 inside, and the surface of the perforations 11 is rifling-structured. The rifling is a concave-convex spiral pattern, wherein multiple concave lines 11b and convex lines 11a are provided, and the number is the same. In this embodiment, there are 6 concave lines 11b and convex lines 11a.

[0028] When the jet pig is used for pipeline cleaning, the fluid medium passes through the perforation 11 and is affected by the rifling trajectory, which promotes the disturbance of the fluid medium and enhances the turbulent kinetic energy of the fluid medium, thereby enhancing the purging ability of the jet pig. In this embodiment, the surface of the perforation 11 is set with a rifling structure, which reduces the weight of the jet pig itself, reduces the wear between the jet pig and the inner wall of the pipeline and the risk of the jet pig getting stuck, and improves the pipeline's transportation efficiency and safety.

[0029] The surface of the main body 10 is symmetrically provided with a first limiting baffle 12 and a second limiting baffle 13, and multiple ribs (not shown in the figure) are provided along the circumference of the main body 10 on the side of the first limiting baffle 12 and the second limiting baffle 13 to reinforce the first limiting baffle 12 and the second limiting baffle 13.

[0030] The first sealing disc 14 and the second sealing disc 15 are respectively sleeved at both ends of the main body 10. The first sealing disc 14 and the second sealing disc 15 are respectively provided with a first through hole 141 and a second through hole 151. The first through hole 141 and the second through hole 151 are evenly arranged on the first sealing disc 14 and the second sealing disc 15 along the circumferential direction of the surface of the main body 10. In this embodiment, the first sealing disc 14 and the second sealing disc 15 are each provided with 6 first through holes 141 and 6 second through holes 151, and the diameter of the first through hole 141 is smaller than that of the second through hole 151.

[0031] When a jet pig is used for pipeline cleaning, by setting through holes of different diameters on the first sealing plate 14 and the second sealing plate 15, the flow rate and velocity of the fluid medium entering from the second through hole 151 and ejected from the first through hole 141 can be increased, thereby enhancing the purging capability of the jet pig.

[0032] The two ends of the main body 10 are respectively provided with a detachable first fixing plate 16 and a second fixing plate 17. The first fixing plate 16 and the second fixing plate 17 are annular. The inner diameter of the first fixing plate 16 and the second fixing plate 17 is the same as the concave diameter of the perforation 11. The first fixing plate 16 and the second fixing plate 17 fix the first sealing disc 14 and the second sealing disc 15 to the other side of the first limiting baffle 12 and the second limiting baffle 13 by bolts.

[0033] like Figure 2 and Figure 3 As shown, in this embodiment, one end of the main body 10 is fixed by four bolts passing through the first fixing plate 16, the first sealing disc 14, and the first limiting baffle 12, respectively; the other end of the main body 10 has the same arrangement. In this embodiment, the sealing disc is detachably fixed to both ends of the main body by bolts, which is beneficial for the installation and use of the jet pig.

[0034] like Figure 1-4 As shown, a positioning device is provided at one end of the perforation 11. The positioning device is a magnetic ring 18, which is gear-shaped. The magnetic ring 18 is clamped and fixed to the end side of the perforation 11 by the second fixing plate 17.

[0035] In this embodiment, by setting an induction magnetic ring 18 on the end side of the perforation 11, the fluid medium will not be obstructed from passing through the perforation 11. When the jet pig moves in the pipeline, the position of the induction magnetic ring 18 can be monitored in real time by the detection device, thereby obtaining the position of the jet pig and preventing the jet pig from being lost in the pipeline and causing pipeline blockage.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
