[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0021] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0022] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection via an intermediate medium; or the internal communication of two components or the interaction between two components. As examples, a direct connection refers to two parts or components being connected together without the need for an intermediate medium, while an indirect connection refers to two parts or components each being connected to at least one intermediate medium, with the connection achieved through the intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Furthermore, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0023] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0024] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0025] In this invention, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientations or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, in the context, it should be understood that when an element is mentioned as being "upper" or "lower" than another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as "upper side," "lower side," "left side," "right side," "front side," and "rear side" not only represent positive orientation but can also be understood as lateral orientation. For example, "above," "on top of," "upper side of," and "above" the first feature "above" or "on the second feature" includes the first feature being directly above, to the upper left, to the upper right, to the upper front, and to the upper rear of the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. The terms "below," "under," "below," and "below" for "first feature" and "second feature" include situations where the first feature is directly below, to the lower left, to the lower right, in front of, or behind the second feature, or simply indicate that the first feature is at a lower horizontal level than the second feature. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0026] In oil and gas extraction, geothermal wells or dual-tube production trees are often selectively used depending on the extraction conditions. Before use, the geothermal wellhead gate valve needs to be directly installed on the casing head, or the dual-tube production tree needs to be installed on the casing crossover. However, a current problem is that the angle of the geothermal wellhead gate valve or dual-tube production tree cannot be adjusted after assembly using existing casing heads or casing crossovers. If the angle is incorrect or the equipment is tilted, all components need to be disassembled and reinstalled, which is difficult and inefficient. To solve the problems in the existing technology, this invention provides a rotary casing structure. The technical solution of this invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 4 As shown, the present invention provides a rotary sleeve structure, which includes a sleeve body 10 and a rotating component 20. The rotating component 20 is disposed on the outer periphery of the sleeve body 10 and located at one end of the sleeve body 10 along the axial direction. The rotating component 20 can rotate around the axis of the sleeve body 10. After the sleeve body 10 is installed in a preset position, when the rotating component 20 is rotated in a clockwise or counterclockwise direction, the rotating component 20 can drive the target device to rotate, so as to adjust the target device to the target position.

[0028] After assembling this rotary sleeve structure with the target equipment, if the angle of the target equipment does not meet the standard, the rotating component 20 can be rotated clockwise or counterclockwise as needed. After assembly, the rotating component 20 can drive the target equipment to rotate until the target angle is reached. No disassembly of the target equipment is required; adjustment can be completed simply by rotating the rotating component 20. The structure is simple, the manufacturing cost is low, the operation is easy, the adjustment speed is fast, the adjustment accuracy is high, and the work effect is good.

[0029] It should be noted that, as Figures 1-4 As shown, the casing body 10 has a through hole 11 along the axial direction, which is used to install the hanger in the mining equipment. In addition, the side wall of the casing body 10 has a connection hole 12 along the radial direction, which is used to connect the side valve of the mining equipment.

[0030] like Figures 1-4 As shown, the rotating assembly 20 includes a flange 21 and a rotating component 22. The flange 21 is disposed on the outer periphery of the sleeve body 10, and a limiting groove is provided in the radial direction of the flange 21. The rotating component 22 is located in the limiting groove. This arrangement not only has a simple structure and is easy to process, but also allows the flange 21 to withstand a large ultimate load, resulting in a more stable structure. In addition, the rotating component 22 is always located in the limiting groove, thereby further ensuring the stability of the flange 21's rotation.

[0031] It should be noted that the rotating component 22 is made of steel balls, and each limiting groove is filled with no less than 100 steel balls. In this structure, no less than 100 steel balls can fill the entire limiting groove, thereby ensuring the stability and smoothness when rotating the flange 21. The choice of steel balls as the rotating component 22 not only facilitates production and reduces manufacturing costs, but also, due to their smooth surface, can significantly improve the rotation effect of the flange 21. Furthermore, the rigid material can withstand a large ultimate load, is not easily damaged, and has a long service life.

[0032] Furthermore, such as Figures 1-2 As shown, flange 21 has a filling groove radially arranged on the side opposite to sleeve body 10, and the filling groove is connected to the limiting groove. The filling groove is used to fill the rotating part 22. In this structure, the filling groove and the limiting groove are matched accordingly, thereby facilitating the filling of the rotating part 22 and ensuring ease of use.

[0033] It should be noted that both the limiting groove and the filling groove are annular. After the structure is locked to the target equipment, the rotating part 22 will be subjected to a large shear force. The annular limiting groove can surround the flange 21, and the multiple steel balls surrounding the flange 21 can effectively reduce the shear force on each steel ball, thus ensuring that it will not be damaged and that the sleeve body 10 and the flange 21 will not easily separate. The annular filling groove can also improve the filling speed and ensure the convenience of filling.

[0034] Preferably, such as Figures 1-2 As shown, the inner diameter of the filling groove is larger than the inner diameter of the limiting groove. By increasing the diameter of the filling groove, the speed at which steel balls are filled into the limiting groove can be increased, thereby improving work efficiency.

[0035] The issue to consider here is that the steel balls may fall out of the filling tank, potentially causing an operational accident. To address this problem, such as... Figures 1-2 As shown, the rotating assembly 20 also includes a sealing element 23, which is disposed within the filling groove and used to seal multiple steel balls. By providing the sealing element 23, multiple steel balls can be sealed by filling the filling groove, thereby preventing steel balls from falling out during operation and causing operational accidents. It should be noted that since the filling groove is annular, the sealing element 23 also needs to be of a corresponding annular structure for sealing.

[0036] To ensure good rotation performance, such as Figure 1 and Figure 2 As shown, multiple limiting grooves are evenly arranged along the axial direction of flange 21, and the filling grooves correspond one-to-one with the limiting grooves. This arrangement can significantly improve the smoothness and stability of rotation, ensuring the adjustment efficiency of the target equipment.

[0037] Furthermore, the flange 21 is coaxially arranged with the sleeve body 10, and can rotate around the axis by an angle of 0°-360°. This arrangement improves the ease of rotation, provides a wide adjustment range, and ensures that the target equipment can be adjusted to any rotation angle.

[0038] Example 1 Based on the above structure, such as Figure 1 and Figure 2 As shown, the geothermal well gate valve 100 is directly installed on the rotary sleeve structure. When the angle of the geothermal well gate valve 100 needs to be adjusted after installation, simply loosen the bolts and rotate the corresponding flange 21 to achieve this, without the need for disassembly and reassembly.

[0039] Example 2 like Figure 3 and Figure 4 As shown, a base 30 is provided at the end of the casing body 10 away from the flange 21. When using the dual-tube wellhead 200, it needs to be installed on a rotating casing structure. At this time, the base 30 can improve the stability, and the angle of the dual-tube wellhead 200 can be adjusted by rotating the flange 21 without disassembly and reassembly.

[0040] In summary, after assembling this rotary sleeve structure with the target equipment, if the angle of the target equipment does not meet the standard, the rotating component 20 can be rotated clockwise or counterclockwise as needed. After assembly, the rotating component 20 can drive the target equipment to rotate until the target angle is reached. No disassembly of the target equipment is required; adjustment can be completed simply by rotating the rotating component 20. This method features a simple structure, low manufacturing cost, easy operation, fast adjustment speed, high adjustment accuracy, and good operational results.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
