Description

Technical Field

[0001] This utility model relates to the field of natural gas extraction technology, specifically to a throttle valve nozzle extraction tool. Background Technology

[0002] The throttle valve nozzle is the core component of the throttle valve, and its main function is to control the flow rate and pressure of fluids. The throttle valve nozzle mainly controls the flow rate and pressure of fluids by changing the size of the throttle orifice. The throttle orifice diameter of a fixed throttle valve nozzle is fixed, and the throttle flow rate needs to be changed by replacing the nozzle body. There are multiple nozzle models in the equipment of a single gas field production and transportation process, but the extraction tools can generally only be adapted to one or two nozzle models. For example, Chinese utility model patent CN204366827U discloses a nozzle disassembly tool. Through the first disassembly sleeve having a first disassembly hole that mates with a first nozzle, and the second disassembly sleeve having a second disassembly hole that mates with a second nozzle, it is possible to use one tool with two nozzle models. However, there are more than two nozzle models in the production and transportation process of a single gas field. Since the size of each disassembly hole cannot be adjusted, a large number of extraction tools are still required, and it is not easy to match them with the nozzles on newly added equipment, resulting in low extraction efficiency and increased tool preparation, purchase and maintenance costs. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology where the disassembly hole size of the throttle valve nozzle extraction tool is not adjustable and cannot be matched with different models of throttle valve nozzles, and to provide a throttle valve nozzle extraction tool.

[0004] This utility model provides a tool for extracting throttle valve nozzles, including: The bracket includes a first link and a second link, which are arranged in a cross shape to form an intersection. A first clamping assembly is passed through the first connecting rod and includes a first clamping member and a second clamping member, wherein the first clamping member and the second clamping member are symmetrically arranged on both sides of the intersection. The second clamping assembly is mounted on the second connecting rod and includes a third clamping member and a fourth clamping member, wherein the third clamping member and the fourth clamping member are symmetrically arranged on both sides of the intersection. The first clamping member, the second clamping member, the third clamping member, and the fourth clamping member enclose and form a clamping space; An adjusting member is provided on the first connecting rod and the second connecting rod respectively. The adjusting member is used to adjust the relative positions of the first clamping member, the second clamping member, the third clamping member and the fourth clamping member.

[0005] This utility model discloses a throttle valve nozzle extraction tool. By adjusting the position of the first clamping component on the first connecting rod and the position of the second clamping component on the second connecting rod, the size of the clamping space can be adjusted. This allows the clamping space to be used with throttle valve nozzles of different sizes and models for extraction operations, expanding the applicability of the extraction tool, reducing the number of tools required for extraction operations, and improving work efficiency.

[0006] Preferably, the intersection includes a limiting block, on which a first connecting hole and a second connecting hole are provided. The axes of the first connecting hole and the second connecting hole are perpendicular and offset vertically. The first connecting rod passes through the first connecting hole, and the second connecting rod passes through the second connecting hole. This allows the positions of the first and second connecting rods relative to the limiting block to be adjusted according to actual conditions, thereby adapting to the extraction of oil nozzles of different positions and models, and further expanding the applicability of the extraction tool.

[0007] Preferably, the limiting block includes a block structure component.

[0008] Preferably, the limiting block includes two nuts welded together. This allows for rapid fabrication and assembly of the limiting block, reducing the manufacturing cost of the extraction tool.

[0009] Preferably, the adjusting component includes a sleeve, which is threadedly connected to the first or second connecting rod. One end of the sleeve abuts against the first or second clamping assembly, and the other end is provided with an adjusting handle. By rotating the adjusting component relative to the first connecting rod, the first clamping assembly can be moved along the first connecting rod, changing the relative distance between the first and second clamping components. Simultaneously, rotating the adjusting component relative to the second connecting rod can change the relative distance between the third and fourth clamping components, thereby adjusting the clamping space and limiting the size of the formed clamping space to ensure the shape stability of the clamping space during use.

[0010] Preferably, the end of the sleeve away from the adjusting handle is provided with an operating part, which is compatible with a torque tool. This allows the adjusting component to be rotated and adjusted using a torque tool such as a wrench if the adjusting handle is damaged.

[0011] Preferably, the first clamping member and the second clamping member each include a flat plate structure, the first clamping member and the second clamping member are respectively perpendicular to the axis of the first connecting rod, and the first clamping member and the second clamping member can contact the outer wall surface of the nozzle.

[0012] Preferably, the third and fourth clamping members are respectively provided with limiting grooves on their adjacent side surfaces, and the limiting grooves can engage with the outer edge of the nozzle. This ensures stable contact between the extraction tool and the nozzle, preventing mutual rotation.

[0013] Preferably, the first clamping member and the second clamping member are each provided with anti-slip parts. This further improves the contact stability between the extraction tool and the nozzle.

[0014] Preferably, a limiting mechanism is provided between the first clamping member and the second clamping member. The limiting mechanism includes a limiting bolt and a limiting nut. The limiting bolt passes through the first clamping member or the second clamping member, and the limiting nut is threadedly engaged with the limiting bolt. This further ensures the shape stability of the clamping space during use.

By adjusting the position of the first clamping component on the first connecting rod and the position of the second clamping component on the second connecting rod, the size of the clamping space can be adjusted, so that the clamping space can be used to extract throttle valve nozzles of different sizes and models, thus expanding the applicability of the extraction tool. 2. This utility model provides a throttle valve nozzle extraction tool. By adjusting the clamping space, it can be used with throttle valve nozzles of different sizes and models, which can reduce the number of tools required for extraction operations and improve work efficiency.

[0025] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0026] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0028] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0029] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0030] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0031] Example 1 like Figures 1-7As shown, a throttle valve nozzle extraction tool includes a bracket 1, a first clamping assembly, a second clamping assembly, and an adjusting member 8. The bracket 1 includes a first connecting rod 11 and a second connecting rod 12, which are arranged in a cross shape to form a cross portion 2. The first clamping assembly passes through the first connecting rod 11 and includes a first clamping member 3 and a second clamping member 4, which are symmetrically arranged on both sides of the cross portion 2. The second clamping assembly passes through the second connecting rod 12 and includes a third clamping member 5 and a fourth clamping member 6, which are symmetrically arranged on both sides of the cross portion 2. The first clamping member 3, the second clamping member 4, the third clamping member 5, and the fourth clamping member 6 enclose a clamping space 7. The first connecting rod 11 and the second connecting rod 12 are respectively provided with adjusting members 8, which are used to adjust the relative positions of the first clamping member 3, the second clamping member 4, the third clamping member 5, and the fourth clamping member 6.

[0032] The bracket 1 is the main body of the extraction tool, which provides a mounting base for the first clamping component and the second clamping component, so that the first clamping component and the second clamping component can enclose and form a clamping space 7 that is adapted to the shape of the nozzle 10.

[0033] In one or more implementations, such as Figure 1 As shown, the bracket 1 can be an integral structural component of the first link 11 and the second link 12 arranged in a cross shape, that is, the first link 11 and the second link 12 are coplanar and perpendicular. By adjusting the position of the first clamping component and the second clamping component on the bracket 1, the relative position of the clamping space 7 and the bracket 1, as well as the adjustment of the size of the clamping space 7, can be realized.

[0034] In an optional embodiment, the first link 11 and the second link 12 may be screws, the first clamping assembly may be slidably disposed on the first link 11, and the second clamping assembly may be slidably disposed on the second link 12.

[0035] In one or more implementations, such as Figures 2-3As shown, the bracket 1 can be a structural component formed by passing a first connecting rod 11 and a second connecting rod 12 through a limiting block 21. The limiting block 21 is provided with a first connecting hole 211 and a second connecting hole 212. The axes of the first connecting hole 211 and the second connecting hole 212 are perpendicular and staggered vertically. The first connecting rod 11 passes through the first connecting hole 211, and the second connecting rod 12 passes through the second connecting hole 212, so that the first connecting rod 11 and the second connecting rod 12 are arranged in a cross shape. In use, the position of the first connecting rod 11 and the second connecting rod 12 relative to the limiting block 21 can be adjusted according to the actual situation to form brackets 1 with different cross shapes, expand the adjustable range of the first clamping component and the second clamping component, and thus adapt to the extraction of oil nozzles 10 of different positions and models, further expanding the applicability of the extraction tool.

[0036] In optional implementations, such as Figure 4 As shown, the limiting block 21 can be an integral block structure, which can be an iron block, an aluminum block, a cylinder, or a prism, and can be selected and adjusted according to the actual situation.

[0037] In optional implementations, such as Figure 3 As shown, the limiting block 21 can be two nuts welded together. Nuts are widely available. By welding two nuts to form the limiting block 21, the limiting block 21 can be quickly prepared and assembled for use, reducing the preparation cost of the extraction tool and facilitating its promotion and application in different fields.

[0038] like Figure 6 As shown, the first clamping assembly and the second clamping assembly are structural components for forming the clamping space 7. The first clamping assembly includes a first clamping member 3 and a second clamping member 4 arranged opposite to each other, and the second clamping assembly includes a third clamping member 5 and a fourth clamping member 6 arranged opposite to each other.

[0039] In one or more embodiments, the first clamping member 3 and the second clamping member 4 each include a flat plate structure. The first clamping member 3 and the second clamping member 4 are respectively perpendicular to the axis of the first connecting rod 11. The first clamping member 3 and the second clamping member 4 can contact the outer wall surface of the nozzle 10.

[0040] In an optional embodiment, the first clamping member 3 and the second clamping member 4 can be iron plates.

[0041] like Figure 7 As shown, in one or more embodiments, the third clamping member 5 and the fourth clamping member 6 are respectively provided with limiting grooves 51 on their adjacent side surfaces. The limiting grooves 51 can engage with the outer edge of the nozzle 10. This ensures stable contact between the extraction tool and the nozzle 10, preventing mutual rotation.

[0042] In an optional embodiment, the third clamping member 5 and the fourth clamping member 6 can be iron plate components, and the limiting groove 51 can be a groove structure formed by bending the iron plate or machining the iron plate. Since the cross-section of the throttle valve nozzle 10 is generally hexagonal, the shape of the limiting groove 51 can be a pointed groove that matches the outer edge of the nozzle 10.

[0043] Adjustment member 8 is a structural member disposed on the first link 11 and the second link 12 to limit the relative position of the first clamping assembly and the second clamping assembly.

[0044] In one or more embodiments, the adjusting member 8 may be a nut disposed on the first connecting rod 11 or the second connecting rod 12. The adjusting member 8 is threadedly connected to the first connecting rod 11 and the second connecting rod 12. By adjusting the position of the adjusting member 8, the first clamping assembly and the second clamping assembly can be moved accordingly, thereby adjusting the size of the formed clamping space 7 and ensuring the shape stability of the clamping space 7 during use.

[0045] In an optional embodiment, adjusting members 8 can be provided at both ends of the first link 11 and the second link 12, respectively, so as to adjust and limit the positions of the first clamping member 3, the second clamping member 4, the third clamping member 5 and the fourth clamping member 6 through each adjusting member 8.

[0046] In one or more implementations, such as Figure 8 As shown, the adjusting component 8 may include a sleeve 81, which is threadedly connected to the first connecting rod 11 or the second connecting rod 12. Rotating the sleeve 81 can cause the sleeve 81 to move relative to the first connecting rod 11 or the second connecting rod 12, so that the sleeve 81 can abut against the corresponding first clamping component or the second clamping component.

[0047] In an optional embodiment, an adjustment handle 82 can be provided at one end of the sleeve 81. The corresponding adjustment component 8 can be rotated with less effort by adjusting the handle 82, so as to facilitate the adjustment and use of the extraction tool.

[0048] In an optional embodiment, the end of the sleeve 81 away from the adjusting handle 82 may be provided with an operating part 83. The operating part 83 may be a nut welded to the end of the sleeve 81, which can be adapted to a torque tool to facilitate auxiliary adjustment by using a wrench or the like when the adjusting handle 82 is damaged or the adjusting part 8 is not working properly.

[0049] In an alternative embodiment, the adjusting handle 82 may be a rod-shaped structure perpendicular to the first link 11 or the second link 12.

[0050] In an alternative implementation, the adjustment handle 82 may be a block structure.

[0051] In one or more implementations, such as Figure 3 As shown, a limiting mechanism 9 is provided between the first clamping member 3 and the second clamping member 4. The limiting mechanism 9 includes a limiting bolt 91 and a limiting nut 92. The limiting bolt 91 passes through the first clamping member 3 or the second clamping member 4, and the limiting nut 92 is threadedly engaged with the limiting bolt 91. The distance between the first clamping member 3 and the second clamping member 4 is limited by the length of the limiting nut 92. In conjunction with the adjusting member, the first clamping member 3 and the second clamping member 4 can maintain a stable distance during use, further ensuring the shape stability of the clamping space 7 during use.

[0052] In one or more embodiments, the first clamping member 3 and the second clamping member 4 are respectively provided with anti-slip parts. This further improves the contact stability between the extraction tool and the nozzle 10.

[0053] In an optional embodiment, the anti-slip part can be a local silicone pad, anti-slip ridges, dotted protrusions, etc., which can make the surface contact between the first clamping component and the outer wall of the oil nozzle 10 more stable.

[0054] In an optional embodiment, the third clamping member 5 and the fourth clamping member 6 are also provided with anti-slip parts.

[0055] The throttle valve nozzle extraction tool of this embodiment can adjust the size of the clamping space 7 by adjusting the position of the first clamping component on the first connecting rod 11 and the position of the second clamping component on the second connecting rod 12. This allows the clamping space 7 to be used with throttle valve nozzles 10 of different sizes and models for extraction operations, expanding the applicability of the extraction tool, reducing the number of tools required for extraction operations, and improving work efficiency.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
