Detailed implementation method:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment of this utility model is an oil and gas recovery pressure control valve assembly. The pressure control valve body 01 used in this application is a product that can be directly purchased on the market. Its principle and connection method are existing technologies known to those skilled in the art, so they will not be described in detail here.

[0025] Includes: a pressure control valve body 01, a disassembly and assembly assembly 03 is provided on the rotating shaft of the pressure control valve body 01, and a labor-saving assembly 02 is provided above the disassembly and assembly assembly 03;

[0026] The labor-saving component 02 includes a turntable 21. Rotating rods 22 are installed inside both sides of the turntable 21. Rotating rods 22 can be rotated outwards around a fixed rod 23, allowing them to completely rotate out of the turntable 21 and return to parallel alignment. The fixed rod 23 passes through the end of the rotating rod 22 furthest from the center of the turntable 21. A rotating plate 24 abuts against the top of the end of the rotating rod 22 closest to the center of the turntable 21. The rotating plate 24 can be rotated around a shaft 25, causing the shaft 25 to no longer abut against the rotating rod 22, allowing the rotating rod 22 to completely rotate out of the turntable 21 and return to parallel alignment. The shaft 25 passes through the middle of the rotating plate 24. The rotating plate 24 is connected to the turntable 21 via a torsion spring 26, which provides elastic force. Under the action of the torsion spring 26, the rotating plate 24 rotates to above the rotating rod 22, limiting its movement.

[0027] Furthermore, the disassembly and assembly component 03 includes an insertion block 31. When the insertion block 31 rotates, it can drive the rotating shaft of the pressure control valve body 01 to rotate. A limiting plate 32 passes through the lower interior of the insertion block 31. After the limiting plate 32 is pulled out of the insertion block 31, the limiting plate 32 can be rotated around the connecting rod 33. After the connecting rod 33 is released, the limiting plate 32 will not be inserted into the insertion block 31. A connecting rod 33 passes through the interior of one end of the limiting plate 32. Connecting blocks 34 are fixedly installed at both ends of the connecting rod 33. A sliding rod 35 is fixedly connected to one side of the connecting block 34. A side block 37 is connected to the outer wall of the sliding rod 35. The sliding rod 35 is connected to the side block 37 through a common spring 36. The common spring 36 provides elastic force. Under the action of the elastic force of the common spring 36, the stability of the position of the sliding rod 35 is maintained, thereby maintaining the stability of the positions of the connecting block 34, the connecting rod 33 and the limiting plate 32.

[0028] Furthermore, the turntable 21 is fixedly connected to the insert block 31 to ensure the integrity of the turntable 21 and the insert block 31. The rotating rod 22 is rotatably connected to the fixed rod 23. The rotating rod 22 is rotated outward around the fixed rod 23 until it is completely rotated out of the turntable 21 and parallel to the turntable 21 again. The fixed rod 23 is fixedly connected to the turntable 21 to ensure the firmness of the fixed rod 23.

[0029] Furthermore, the rotating plate 24 is rotatably connected to the shaft 25, allowing the rotating plate 24 to rotate around the shaft 25 so that the shaft 25 no longer blocks the rotating rod 22, allowing the rotating rod 22 to rotate completely out of the turntable 21 and back to be parallel to the turntable 21. The shaft 25 is fixedly connected to the turntable 21, ensuring the stability of the shaft 25 position.

[0030] Furthermore, the two ends of the torsion spring 26 are fixedly connected to the turntable 21 and the rotating plate 24 respectively. The torsion spring 26 provides elastic force. Under the action of the elastic force of the torsion spring 26, the rotating plate 24 rotates to the top of the rotating rod 22 and limits the rotating rod 22. The limiting plate 32 is slidably connected to the insert block 31. The limiting plate 32 can be pulled out of the insert block 31, and then the insert block 31 and the turntable 21 can be removed.

[0031] Furthermore, the insert 31 is inserted into the rotating shaft of the pressure control valve body 01. When the insert 31 rotates, it can drive the rotating shaft of the pressure control valve body 01 to rotate. The limiting plate 32 is rotatably connected to the connecting rod 33. After the limiting plate 32 is pulled out of the insert 31, the limiting plate 32 can be rotated around the connecting rod 33. After the connecting rod 33 is released, the limiting plate 32 will not be inserted into the insert 31. The slide rod 35 is slidably connected to the side block 37 to ensure that the side block 37 does not affect the movement of the slide rod 35.

[0032] Furthermore, the two ends of the ordinary spring 36 are fixedly connected to the slide rod 35 and the side block 37 respectively. The ordinary spring 36 provides elastic force, which maintains the stability of the position of the slide rod 35 under the action of the elastic force of the ordinary spring 36, thereby maintaining the stability of the positions of the connecting block 34, the connecting rod 33 and the limiting plate 32. The side block 37 is fixedly connected to the pressure control valve body 01 to ensure the firmness of the position of the side block 37.

[0033] Working principle: In use, first rotate the rotating plate 24 around the shaft 25 so that the rotating plate 24 no longer blocks the rotating rod 22. Then rotate the rotating rod 22 outwards around the fixed rod 23. After the rotating rod 22 is completely rotated out of the turntable 21 and parallel to the turntable 21 again, the worker holds the end of the rotating rod 22 away from the fixed rod 23 with both hands. Using the lever principle, the turntable 21 is rotated. After pressure adjustment, the connecting rod 33 can be held and moved away from the insert block 31. The connecting rod 33 drives the limiting plate 32 to gradually pull out the insert block 31, allowing the insert block 31 and the turntable 21 to be removed. The above is the complete working principle of this utility model.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
