[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] Embodiment 1

[0027] A multifunctional oil nozzle for oil field production comprises a pipe body 1 and an oil outlet 2, wherein the oil outlet 2 is fixedly arranged on one side of the pipe body 1, a first cavity 3 and a second cavity 4 are arranged inside the pipe body 1, a flow regulating mechanism is arranged inside the pipe body 1, and the flow regulating mechanism comprises a threaded rod 5, a knob 6, a connecting portion 7, a sleeve 8 and a through hole 9, the through hole 9 is arranged in an array on the surface of the sleeve 8, the sleeve 8 is slidably arranged in the pipe body 1, and the two ends of the sleeve 8 extend into the first cavity 3 and the second cavity 4 respectively, and the sleeve 8 and the first cavity 3 and the second cavity 4 are connected. A limiting mechanism is arranged between the two cavities 4, the connecting part 7 is fixedly arranged on the top of the sleeve 8, the knob 6 is fixed on one end of the threaded rod 5, the other end of the threaded rod 5 penetrates and is rotatably arranged on the surface of the tube body 1, and one end of the threaded rod 5 is threadedly connected to the center part of the connecting part 7. The limiting mechanism includes a limiting rod 10 and a limiting ring 11, the limiting rod 10 is vertically fixed to the inner wall of the second cavity 4, the limiting ring 11 is fixedly arranged on the surface of the sleeve 8, and the limiting ring 11 is slidably arranged on the surface of the limiting rod 10.

[0028] See also Figure 1 and 2 , the oil and gas enter the sleeve 8 from the second cavity 4, enter the first cavity 3 after being filtered through the through holes 9 on the surface of the sleeve 8, and finally enter the oil outlet 2 through the first cavity 3 for discharge. When the flow of oil and gas needs to be adjusted, the knob 6 is turned to drive the threaded rod 5 to rotate. When the threaded rod 5 rotates, it can drive the connecting part 7 to gradually rise inside the tube body 1. At this time, the connecting part 7 can drive the sleeve 8 to gradually rise. As the height of the sleeve 8 increases, more through holes 9 on its surface will enter the first cavity 3. At this time, the total area of ​​the through holes 9 connected to the first cavity 3 increases, thereby achieving an increase in the flow rate of oil and gas. During the axial movement of the sleeve 8, the limit ring 11 can be driven to move synchronously on the surface of the limit rod 10. The circumferential limit of the sleeve 8 can be achieved through the cooperation of the limit rod 10 and the limit ring 11, so that the height of the sleeve 8 can be adjusted through the threaded rod 5 and the connecting part 7.

[0029] The cross section of the through hole 9 is set to a conical structure, the end of the through hole 9 with a larger diameter points to the inner wall of the through hole 9, and the end of the through hole 9 with a smaller diameter points to the outer wall of the through hole 9.

[0030] See also Figure 5 Since the oil and gas enter from the inside of the sleeve 8 and enter the first cavity 3 after passing through the through hole 9, the end of the through hole 9 with a smaller diameter plays a filtering role, while the end of the through hole 9 with a larger diameter can increase the volume of the through hole 9, so that the inside of the through hole 9 can accommodate more oil and gas, thereby improving the filtering efficiency of the oil and gas, and the end of the through hole 9 with a larger diameter can also accommodate more solid impurities.

[0031] An auxiliary adjustment mechanism is arranged at the top of the connecting portion 7, and the auxiliary adjustment mechanism includes a sealing plate 12 and an adjustment seat 13. The adjustment seat 13 is concentrically arranged at the top of the sealing plate 12, and the adjustment seat 13 and the sealing plate 12 are both slidably arranged on the inner wall of the first cavity 3. The sealing plate 12 is fixedly arranged on the surface of the connecting portion 7. The connecting portion 7 is arranged as a conical structure as a whole. The connection between the sealing plate 12 and the connecting portion 7 is arranged as an arc surface 19, and the central angle corresponding to the arc surface 19 is 90°.

[0032] See also Figure 3If the threaded rod 5 is in contact with oil and gas for a long time, the surface of the threaded rod 5 will be corroded, so that the threaded rod 5 cannot be engaged with the connecting portion 7. Therefore, on the one hand, the present embodiment fills the gap between the first cavity 3 and the connecting portion 7 through the sealing plate 12 and the adjusting seat 13, and in order to ensure the sealing, the side wall of the adjusting seat 13 also needs to be embedded with a sealing ring. On the other hand, since the side surfaces of the sealing plate 12 and the adjusting seat 13 are in contact with the oil outlet 2, the height of the sealing plate 12 and the adjusting seat 13 can be adjusted. The cross-sectional area of ​​the connection point between the oil outlet 2 and the first cavity 3 is adjusted to achieve auxiliary adjustment of the oil and gas flow rate. When the sleeve 8 rises, the number of through holes 9 exposed in the first cavity 3 increases. At this time, the flow rate inside the sleeve 8 increases. As the sleeve 8 rises, the sleeve 8 can drive the sealing plate 12 and the adjustment seat 13 to rise synchronously through the connecting part 7. At this time, the cross-sectional area of ​​the connection point between the oil outlet 2 and the first cavity 3 gradually increases, and the flow rate at this part will also increase. Conversely, when the flow rate inside the sleeve 8 decreases, the flow rate at this part will also decrease.

[0033] It should be noted that in this embodiment, the connection between the sealing plate 12 and the connecting portion 7 is set as an arc surface 19 with a central angle of 90°, which can reduce the impact force of oil and gas on the connection between the sealing plate 12 and the connecting portion 7, thereby increasing the service life of each component.

[0034] Embodiment 2

[0035] In the above scheme, the output flow rate of oil and gas can be controlled while filtering the oil and gas through the flow regulating mechanism and the auxiliary regulating mechanism. However, when the flow rate inside the first cavity 3 is small, the impact force of the oil and gas on the threaded rod 5 is large, which makes it possible for the threaded rod 5 to be damaged. Therefore, in this embodiment, a supporting mechanism is arranged between the first cavity 3 and the sealing plate 12. The supporting mechanism includes a supporting arm 14, a connecting seat 15 and a movable seat 16. The connecting seat 15 is fixedly arranged on the top of the first cavity 3, and the connecting seat 15 is sleeved on the surface of the threaded rod 5. The top end of the support arm 14 is hinged to the side of the connecting seat 15, and the movable seat 16 is hinged to the bottom end of the support arm 14. The movable seat 16 is slidably arranged on the surface of the sealing plate 12 through a sliding member. The sliding member includes a T-shaped track 17 and a slide groove 18. The slide groove 18 is arranged on the surface of the movable seat 16. The T-shaped track 17 is fixedly arranged on the surface of the sealing plate 12, and the movable seat 16 is slidably arranged on the surface of the T-shaped track 17 through the slide groove 18.

[0036] See also Figure 3 and 4When the sealing plate 12 drives the adjustment seat 13 to move upward, since the overall length of the support arm 14 is unchanged, the top of the support arm 14 will rotate on the side of the connecting seat 15, and the bottom of the support arm 14 will also rotate on the surface of the movable seat 16. At this time, as the sealing plate 12 moves upward, the bottom of the support arm 14 will drive the movable seat 16 to move on the surface of the T-shaped track 17 away from the threaded rod 5 until the movable seat 16 moves to the end of the T-shaped track 17. In the above process, the support arm 14 is always inclined from the initial state to the end state, so the support arm 14 can form a triangular structure with the sealing plate 12 and the threaded rod 5, thereby playing a supporting role between the first cavity 3 and the sealing plate 12 to resist the impact force of oil and gas.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
