However, current flange tightening procedures present challenges: accurately controlling the applied tightening force and establishing clear tightening standards are difficult. This can lead to leaks due to insufficient tightening or damage to flanges from over-tightening. Furthermore, flange tightening is challenging in space-constrained areas. Therefore, accurately controlling the tightening torque of pipe flanges, making it easily identifiable, and applicable to flange tightening operations of different sizes and in any area are problems that need to be solved by those skilled in the art.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0030] like Figures 1-6As shown, this embodiment provides a pipe flange locking fixture, including a torque wrench 10, a connector 20, and a locking belt 30. The connector 20 and the torque wrench 10 are inserted into each other. The torque wrench 10 can be set with any torque value. The locking belt 30 is connected to the connector 20 and can form a sleeve with the connector 20 to be fitted onto the outside of the pipe flange. The inner diameter of the sleeve is adjustable.

[0031] Specifically, in this embodiment, the torque wrench 10 can be set to any torque value, enabling standardized implementation of pipe flange locking. Based on the set torque value, the torque force applied to the pipe flange can be limited, thus establishing a standardized operating procedure and preventing problems such as loose pipes or damage to the flange due to over-tightening. Furthermore, the connector 20 and the torque wrench 10 are connected via a plug-in connection, facilitating categorized storage and portability, allowing operation in any area, and correspondingly reducing operating costs. It also facilitates future expansion of the torque wrench 10's use. The locking belt 30 connects to the connector 20, forming a sleeve that can be fitted onto the outside of the pipe flange, allowing the entire device to be relatively fixed to the flange structure. The inner diameter of the sleeve is adjustable, making it suitable for locking pipe flanges of different sizes, improving both compatibility and locking efficiency.

[0032] The specific structure of the pipe locking fixture in this embodiment is described below.

[0033] like Figure 1As shown, in this embodiment, the pipe flange locking fixture includes a torque wrench 10, a connector 20, and a locking belt 30. The fixture is primarily used for locking the pipe flange, ensuring accurate and controllable locking force to prevent damage. Optionally, in this embodiment, the connector 20 and the torque wrench 10 are interlocked, allowing for categorized storage, easy disassembly and transport, and applicability to pipe flange locking operations in different areas. This also facilitates future expansion of the torque wrench 10's use. Furthermore, the torque wrench 10 can be set with any torque value. In other embodiments, when locking the pipe flange, if the torque reaches the set value, rotation will cease and a warning sound, such as a "click," will be emitted to alert the operator, thus controlling the locking process and limiting the torque range. For example, the torque wrench 10 can be a wrench that directly displays and adjusts the torque value; specific models are not limited here. Furthermore, the locking belt 30 is connected to the connector 20 to ensure its flexible application. Simultaneously, the locking belt 30 forms a sleeve around the connector 20, which is then fitted onto the outside of the pipe flange, allowing the pipe flange locking fixture to be stably connected to the pipe flange and facilitating its locking. For example, the inner diameter of the sleeve is adjustable to accommodate pipe flanges of different sizes, thus expanding the applicability of the pipe flange locking fixture.

[0034] Combination Figures 2-6 As shown, in this embodiment, the torque wrench 10 includes an adjusting part 11 and a connecting part 12. Optionally, the adjusting part 11 is used to set the torque value, and the adjusting part 11 is provided with a torque scale, so that the torque force applied during the tightening process can be set to ensure that the tightening process is accurate and controllable, and the standard of the tightening operation can be determined. At the same time, the torque value can be displayed intuitively on the adjusting part 11, so that the operator can quickly determine whether it is tightened, thereby avoiding damage to the pipe fitting due to over-tightening. Further, the connecting part 12 is provided on the adjusting part 11, which facilitates the operator to apply torque force. Exemplarily, the pipe fitting tightening fixture is also provided with an extension component, and a connection port is provided on the torque wrench 10, so that the extension component can be inserted into the connection port to extend the length of the torque wrench 10. The extension component can be provided on the adjusting part 11 or between the adjusting part 11 and the connecting part 12, which can be set as needed and is not limited here.

[0035] Furthermore, the connector 20 can be inserted into the connecting part 12 to achieve a stable connection between the torque wrench 10 and the connector 20. For example, the end of the connecting part 12 facing away from the adjusting part 11 is provided with a square block, and one end of the connector 20 is provided with a square groove. The square groove and the square block can be inserted into each other to achieve a detachable connection. In other embodiments, a locking structure can also be provided on the connecting part 12 to lock their positions after the connector 20 and the connecting part 12 are inserted and connected, ensuring the stability of subsequent pipe tightening operations. Whether to lock and the locking method can be set by those skilled in the art as needed, and will not be elaborated here.

[0036] Optionally, in this embodiment, the connector 20 is provided with a fixing pin 201, a through hole 202, and an abutment surface 203. Specifically, in this embodiment, the connector 20 is configured with an arc-shaped structure, and the sleeve is located on the outer arc side of the connector 20. A through hole 202 is provided through the middle part of the connector 20, and a fixing pin 201 is provided at the bottom of the through hole 202. Specifically, the locking belt 30 is rotatably connected to the fixing pin 201, which not only ensures the stable installation of the locking belt 30 on the connector 20, but also ensures the flexible operation of the locking belt 30, which can be rotated and adjusted according to the position of the pipe fitting.

[0037] Furthermore, the locking belt 30 can be inserted into and locked in the through hole 202, thereby ensuring that the position of the locking belt 30 does not change when it is fitted onto the outside of the pipe flange. For example, a locking element is provided in the through hole 202, and the locking element can be an elastic band, an inner clamp, etc., simply requiring the locking belt 30 to be fixed in the through hole 202. In other embodiments, the locking belt 30 can also be made of a material with good frictional properties. In this way, simply inserting the locking belt 30 through the through hole 202 and pressing it tightly against the pipe flange allows the pipe flange to rotate under the frictional effect between the locking belt 30 and the pipe flange, as well as under the rotation of the torque wrench 10, to complete the locking operation. The specific method of locking the locking belt 30 can be configured as needed by those skilled in the art, and is not limited here.

[0038] Furthermore, an abutment surface 203 is provided on the outer arc side of the connector 20, that is, the abutment surface 203 is located on the sleeve side, and when the locking belt 30 is sleeved on the outside of the pipe flange, the abutment surface 203 can press against the locking belt 30, so that the operator can apply torque force more effectively. For example, the connector 20 can be manufactured in various sizes and types to meet the locking requirements of different types of pipe flanges.

[0039] Optionally, the two ends of the locking belt 30 are respectively configured as a rotating end 301 and a movable end 302. Specifically, the rotating end 301 is provided with a rotating sleeve, which is fitted onto the outside of the fixed pin 201, thereby achieving the connection between the rotating end 301 and the fixed pin 201, allowing the locking belt 30 to be adjusted relative to the connector 20 to better fit the outside of the pipe flange. Further, the movable end 302 can pass through the through hole 202, thereby allowing the middle part of the locking belt 30 to be locked in the through hole 202, forming a sleeve. Specifically, by adjusting the distance between the movable end 302 and the through hole 202 after the movable end 302 passes through the through hole 202, the inner diameter of the sleeve can be changed, thus making it suitable for pipe flanges of different sizes and expanding the applicability of the pipe flange locking tool.

[0040] Therefore, in this embodiment, after the movable end 302 of the locking belt 30 passes through the through hole 202 of the connector 20, the locking belt 30 is fitted onto the outside of the pipe flange, so that the abutment surface 203 can press against the outside of the locking belt 30, thereby making the locking belt 30 and the pipe flange tightly fit together. Finally, by setting the torque value on the torque wrench 10 and holding the adjustment part 11 of the torque wrench 10 to lock the pipe flange, the pipe flange can be locked under the standard torque, so that the locking operation standard can be judged, the locking judgment and identification is no longer difficult, and the problem of pipe flange damage caused by over-tightening is avoided. Furthermore, the pipe flange locking fixture in this embodiment is also suitable for locking pipe flanges in space-constrained areas, and locking the pipe flange according to the set standard torque can avoid problems such as leakage or damage to the pipe due to poor flange locking.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
