Description

Technical Field

[0001] This utility model relates to the field of gas injection valve technology, specifically a gas injection valve for oil wells. Background Technology

[0002] In the process of oil and gas extraction, a considerable portion of crude oil cannot be extracted underground, making the extraction of remaining oil and complex oil and gas reservoirs particularly important. To improve crude oil recovery, oil recovery technologies such as gas injection are increasingly used, often requiring the use of gas injection valves. However, existing gas injection valves for oil wells still encounter some problems in actual use.

[0003] For example, application number 201720050936.4 specifically describes a heated gas injection valve for oil well production. It includes a gas injection valve body, a splined shaft, and a gas injection valve assembly. The upper end of the gas injection valve body has a gas injection port. The gas injection valve assembly is housed within the gas injection valve body and slidably connected to the inner wall of the gas injection valve body. The splined shaft is inserted into the gas injection valve assembly. This design reduces the number of operations, decreases labor intensity, and improves oil production efficiency. Existing gas injection valves are often fixedly connected to their bases, making maintenance difficult when malfunctions occur, significantly impacting performance. Most existing gas injection valves have a simple structure, making it inconvenient to adjust the internal flow rate and adapt quickly to changing external demands, thus affecting work efficiency.

[0004] To address the aforementioned problems, a gas injection valve for oil wells is proposed. Utility Model Content

By using this device, the problems of existing air injection valves, which are often fixedly connected to their bases, are difficult to maintain when malfunctioning, greatly affecting their performance. Existing air injection valves are mostly simple in structure, making it inconvenient to adjust their internal flow rate and difficult to quickly adjust when external demands change, thus affecting work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil well gas injection valve, comprising a base and a gas injection valve body disposed on the top of the base, wherein the base has a placement groove, a support plate is fixedly connected to the bottom of the gas injection valve body, and the support plate matches the placement groove, a rotating knob is rotatably connected to the top of the base, and the bottom of the rotating knob extends into the interior of the base and is fixedly connected to a bevel gear, and a placement chamber is fixedly connected to one end of the gas injection valve body, and a placement plate is fixedly connected inside the placement chamber.

[0027] 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.

[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0029] Combination Figures 1-4An air injection valve for oil wells includes a base 1 and an air injection valve body 2 disposed on the top of the base 1. The base 1 has a placement groove 11. A support plate 21 is fixedly connected to the bottom of the air injection valve body 2, and the support plate 21 matches the placement groove 11. A rotating knob 12 is rotatably connected to the top of the base 1, and the bottom of the rotating knob 12 extends into the interior of the base 1 and is fixedly connected to a bevel gear 121. A placement chamber 22 is fixedly connected to one end of the air injection valve body 2, and a placement plate 221 is fixedly connected inside the placement chamber 22.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example 1:

[0032] To address the problem that existing air injection valves are often fixedly connected to their base 1, making maintenance difficult and significantly impacting performance when malfunctions, the following solution is proposed. Please refer to the following for details. Figures 1-3 A soft pad 111 is fixedly connected to the top of the base 1, and the soft pad 111 matches the support plate 21. A bevel gear 122 is meshed with one side of the first bevel gear 121. A positive and negative threaded rod 123 is fixedly connected to one side of the second bevel gear 122, and sliding blocks 124 are threaded to both ends of the positive and negative threaded rod 123. The sliding blocks 124 are slidably connected inside the base 1. A locking block 125 is fixedly connected to the top of the sliding block 124. A handle 211 is fixedly connected to the top of the support plate 21. A locking groove 212 is provided on the support plate 21, and the locking groove 212 matches the locking block 125. When maintenance of the air injection valve body 2 is required, the rotary knob located on the top of the base 1 can be rotated. 12. Rotating knob 12 drives bevel gear 121 to rotate, which in turn causes bevel gear 122 to rotate. Bevel gear 122 moves two sets of sliding blocks 124 through the positive and negative threaded rods 123, thereby causing the locking block 125 to move out of the slot 212. At this time, the air injection valve body 2 can be removed from the base 1 by the handle 211. When installation is required, the support plate 21 at the bottom of the air injection valve body 2 is aligned with the placement slot 11 and placed in, so that the soft pad 111 is aligned with the support plate 21. Then, rotating knob 12 in the opposite direction moves the locking block 125 into the slot 212. This makes it easier to remove the air injection valve body 2 from the base 1 and improves the usage effect.

[0033] Example 2:

[0034] To address the issue that most existing air injection valves have a simple structure, making it inconvenient to adjust their internal flow rate during use and hindering quick adjustments when external demands change, thus affecting work efficiency, the following solution is disclosed. Please refer to the details. Figure 1 and Figure 4The placement chamber 22 is also fixedly connected to a drive motor 23. A through-hole 222 is provided on one side of the placement plate 221, and a sealing gasket 223 is fixedly connected to one side of the placement plate 221. A threaded rod 231 is fixedly connected to the output end of the drive motor 23, and a sealing plate 232 is threadedly connected to the outer side of the threaded rod 231. The sealing plate 232 is slidably connected inside the placement plate 221. A flow port matching the through-hole 222 is provided on the sealing plate 232. When it is necessary to control the flow rate of the pipeline inside the air injection valve body 2, the placement can be activated. The drive motor 23 inside chamber 22 drives the threaded rod 231 to rotate, which in turn causes the sealing plate 232 to slide inside the placement plate 221. At this time, the opening and closing degree of the flow port on the sealing plate 232 and the through port 222 on the placement plate 221 changes, thereby controlling the flow rate. The setting of the sealing gasket 223 on one side of the placement plate 221 improves the sealing performance of the overall device, avoids leakage during the adjustment process, and realizes the function of stable adjustment of the flow rate inside the base 1, thus improving the efficiency of use.
