Description

Technical Field

[0001] This application relates to the field of temperature control equipment technology for industrial applications, specifically to a support structure for an extended pipeline. Background Technology

[0002] Existing units all have extended piping that can be directly connected to the customer's workstation. If the extended length is too large, the piping becomes a cantilever beam, which is prone to leakage due to increased deflection. Therefore, support brackets must be added to the cantilever section to ensure stability. Currently, two common bracket types are used: (1) Bottom support clamp type: A bracket is installed below the pipeline and clamped at an appropriate position at the front end; (2) Pipe clamp type: suitable for straight pipe sections with the same diameter, which are fixed by brackets and pipe clamps.

[0003] Analyzing the existing bottom-support clamp-type supports in terms of degrees of freedom after fixation, the vertical degree of freedom is restricted by the support's support, while the vertical degree of freedom is restricted by the clamp. The front-to-back degree of freedom is self-limited by the pipeline. In terms of lateral degree of freedom, due to inherent limitations such as the large clamp gap, it cannot accurately restrict the pipeline, resulting in potential lateral swaying and a fixation defect. Furthermore, the pipe clamp structure is only suitable for straight pipe sections with a uniform diameter; when the pipeline contains various structural forms such as diameter changes, joints, or valves, the pipe clamp becomes difficult to effectively hold the pipe in place. Utility Model Content

[0004] In view of this, the main objective of this application is to provide a support structure for extended pipes, which helps to solve the problem of the fixation defects of existing methods for fixing extended pipes.

[0005] This application provides a support structure for an extended pipeline, which is used to support the geometric connection structure of a terminal ball valve and a secondary terminal ball valve, comprising: The limiting bracket has a geometric support part at its upper end to adapt to the geometric connection structure, and a connecting and fixing part at its lower end. The bracket has the connecting and fixing part mounted on its upper end face, and the rear end of the bracket is mounted on the equipment mounting panel of the terminal ball valve or the secondary terminal ball valve.

[0006] Therefore, this application eliminates the clamp form and adds a limiting bracket. The limiting bracket is used to fix the terminal ball valve or the secondary terminal ball valve. The limiting bracket limits on multiple surfaces, so that the vertical and horizontal degrees of freedom of the extended pipeline simultaneously meet the limiting requirements. Traditional terminal connections require two wrenches, one for fixing the valve seat and one for tightening the ferrule. When fixing the terminal ball valve, the newly added limiting bracket can mimic the wrench form and replace one of the wrenches to achieve single-wrench operation, simplifying the installation and connection. The limiting bracket sets the geometry of its support part according to the geometric connection structure of the terminal ball valve and the secondary terminal ball valve, accurately fixing the complex extended pipeline from multiple degrees of freedom. The limiting bracket provides stable and reliable limiting, is simple and neat, easy to install, and covers a wide range of installation conditions.

[0007] Optionally, the geometric support portion is provided with a geometric slot, and the top of the geometric slot is open.

[0008] The semi-open slot design allows for the use of geometric connection structures that accommodate, support, and limit terminal or sub-terminal ball valves from bottom to top.

[0009] Optionally, the geometric support portion is provided with a horizontally penetrating geometric through hole.

[0010] As described above, the geometric connection structure of the terminal ball valve or the secondary terminal ball valve passes through the geometric through hole, accurately locking the geometric connection structure in the geometric through hole, ensuring the assembly accuracy of the geometric through hole and the geometric connection structure.

[0011] Optionally, the bracket has two first elongated slots arranged in parallel, wherein the bracket includes: a top panel located on the upper end face of the bracket, on which one or two first elongated slots are provided; a rear panel located at the rear end of the top panel, on which two elongated slot mounting holes are arranged in parallel; and two side panels symmetrically distributed on the lower ends of the two sides of the top panel, wherein the number of first elongated slots provided on one side panel is at most one.

[0012] As shown above, the first elongated slot facilitates the adjustment of the front and rear positions of the connecting and fixing parts of the limiting bracket according to actual needs, thereby enhancing the front and rear freedom of the support structure; the rear panel is mounted on the equipment mounting panel through the elongated slot mounting hole, which allows the bracket to be adjusted up and down, further enhancing the vertical freedom of the support structure; the rear panel and the two side panels work together to provide stronger structural support.

[0013] Optionally, both ends of the connecting fixing part are provided with a second elongated slot for fixing the connecting fixing part to the bracket by bolts.

[0014] As shown above, the limiting bracket and the bracket are fixed together by the second long slot, and the long slot is used for adjustment and fixation. This method is suitable for the natural state of the extended pipe. The second long slot avoids applying unnecessary external force to the extended pipe in terms of left and right degrees of freedom.

[0015] Optionally, the connecting fixing part is L-shaped, and one of the second elongated slots is located on the top panel, and the other of the second elongated slots is located on the side panel.

[0016] As shown above, in order to support the secondary terminal ball valve, the connecting and fixing part of the limiting bracket is set in an L-shape, so that the second long slot at one end of the connecting and fixing part and the first long slot on the side panel are located below the extended pipe, thus not affecting the connection between the extended pipe and other components.

[0017] Optionally, the bracket includes: a side plate arranged along the length of the extended pipe; a front right-angle plate with the connecting fixing part mounted on its top end, the right angle of the front right-angle plate facing rearward and the front right-angle plate being located in front of the left side of the side plate; and a rear right-angle plate located behind the right side of the side plate, the right angle of the rear right-angle plate facing forward and the rear right-angle plate having a long slot mounting hole.

[0018] As shown above, the right angle of the front right-angle plate is set to face backward, and the right angle of the rear right-angle plate is set to face forward, which can significantly enhance the stability of the bracket.

[0019] Optionally, the two elongated mounting holes are vertically arranged on the vertical surface of the rear right-angle plate.

[0020] As shown above, the two elongated mounting holes are vertically set on the vertical surface of the rear right-angle plate, allowing the bracket to be adjusted up and down, thus enhancing the bracket's vertical freedom.

[0021] Optionally, the bracket includes: a Z-shaped side plate, which is arranged along the length of the extended pipe, and the rear end of the Z-shaped side plate is provided with a long groove mounting hole; and a cover plate, which is arranged at the lower front end of the Z-shaped side plate.

[0022] As shown above, the Z-shaped side plate is composed of multiple folded edges, which can effectively improve the bending resistance of the side plate in the direction perpendicular to the pipeline; the long slot mounting hole at the rear end of the Z-shaped side plate supports the bracket to be finely adjusted up and down; the cover plate is located at the lower front end of the Z-shaped side plate, and the cover plate serves as a support surface to support the limiting bracket below the extended pipeline.

[0023] Optionally, the connecting fixing part is arranged in an inverted U-shape, and a through hole is provided on the lower side of the front end of the Z-shaped side plate. The inverted U-shaped side passes through the through hole and is located on one side of the cover plate.

[0024] As shown above, the inverted U-shaped design enables the connecting and fixing parts to provide stronger mechanical locking capabilities, effectively preventing loosening or displacement when subjected to lateral forces.

[0025] In summary, the support structure for the extended pipeline provided in this application mainly includes a limiting bracket and a support bracket. Both the limiting bracket and the support bracket are adjusted and fixed via elongated slots, facilitating adaptation to the natural state of the extended pipeline and avoiding unnecessary external forces. The limiting bracket provides stable and reliable positioning, is easy to install, covers a wide range of installation conditions, and has a neat and aesthetically pleasing appearance. Since traditional terminal connections require two wrenches—one for fixing the valve seat and the other for installing the ferrule—the limiting bracket designed in this application can replace one wrench when fixing the terminal ball valve, enabling single-wrench operation and simplifying installation. The limiting bracket, used to fix terminal or secondary terminal ball valves, mimics the wrench shape and can limit movement on multiple surfaces, simultaneously satisfying the limiting requirements for vertical, horizontal, and vertical freedom.

The top panel 201 is provided with two parallel long slots, and the length directions of the first long slots and the second long slots are perpendicular, i.e., they are arranged in a cross shape. This allows the limiting bracket 1 to be finely adjusted in the front-back direction and the left-right direction. The first long slots and the second long slots are fixed in position by bolts. The rear panel 202 is provided with two parallel long slot mounting holes, and the length direction of the long slot mounting holes is vertical, which facilitates the bracket 2 to be finely adjusted in the up-down direction on the equipment mounting panel.

[0050] In such Figure 2 In the schematic diagram shown, the structure and function of the limiting bracket 1 are the same as those of the other brackets. Figure 1 The limit bracket 1 is exactly the same as that in the previous one, so the limit bracket 1 will not be described again here.

[0059] Specifically, to support the secondary terminal ball valve, the connecting and fixing part 102 of the limiting bracket 1 is set in an L-shape, so that the second long slot at one end of the connecting and fixing part 102 and the first long slot on the side panel are located below the extended pipe, so as not to affect the connection between the extended pipe and other components.

[0060] In such Figure 3 In the schematic diagram shown, with Figure 3 Taking the orientation shown as an example, bracket 2 includes a top panel 201, a rear panel 202, and two side panels 203. Figure 3 The embodiments described herein are specifically designed for fixing secondary terminal ball valves, and the length of the top panel 201 is greater than [a certain value]. Figure 1 The length in. Figure 3 In the design, a first elongated slot is provided on the left side of the top panel 201, and another first elongated slot is provided on the side panel 203 at the right end of the bracket 2. The two first elongated slots are arranged in parallel.

The first elongated slot on the top panel 201 and the second elongated slot on the left side of the connecting fixing part 102 are arranged in a cross shape, and the first elongated slot on the side panel 203 and the second elongated slot at the lower right side of the connecting fixing part 102 are arranged in a cross shape. This allows the limit bracket 1 to be finely adjusted in the front-back direction and the left-right direction.

[0061] [Fourth Specific Embodiment] Optionally, the geometric support portion 101 is provided with a horizontally penetrating geometric through hole.

[0062] Specifically, the geometric connection structure of the terminal ball valve or the secondary terminal ball valve passes through the geometric through hole, accurately locking the geometric connection structure in the geometric through hole, ensuring the assembly accuracy of the geometric through hole and the geometric connection structure.

[0064] Specifically, the Z-shaped side plate 221 is composed of multiple folded edges, which can effectively improve the bending resistance of the side plate in the direction perpendicular to the pipeline; the long slot mounting hole at the rear end of the Z-shaped side plate 221 supports the bracket 2 to be finely adjusted up and down; the cover plate 222 is located at the lower front end of the Z-shaped side plate 221, and the cover plate 222 serves as a support surface to support the limiting bracket 1 below the extended pipeline.

[0066] Specifically, the inverted U-shaped design enables the connecting fixing part 102 to provide stronger mechanical locking capability, effectively preventing loosening or displacement when subjected to lateral force.

[0067] In such Figure 4 In the schematic diagram shown, with Figure 4 Taking the indicated direction as an example, Figure 4 The embodiment described is specifically designed for fixing a secondary terminal ball valve. Based on the external hexagonal connection structure of the secondary terminal ball valve, the geometric support portion 101 at the upper end of the limiting bracket 1 is configured as a hexagonal through hole. The external hexagonal connection structure is inserted through the hexagonal through hole and fits tightly. The hexagonal through hole is similar to a hexagonal wrench. The connecting and fixing portion 102 at the lower end of the limiting bracket 1 is inverted U-shaped, with second elongated slots at both ends of the inverted U-shape. The Z-shaped side plate 221 includes an upper flange 221a, a web 221b, and a lower flange 221c, arranged in a Z-shape. The upper flange 221a extends to the left of the web 221b, and the lower flange 221c extends to the right of the web 221b. A cover plate 222 is located at the lower front end of the Z-shaped side plate 221. The cover plate 222 mainly includes an upper top plate 222a, a left side plate 222b, and a right side plate 222c. The left side plate 222b and the right side plate 222c are respectively provided with first elongated slots for installing second elongated slots of the limiting bracket 1. The first elongated slots at both ends of the cover plate 222 and the second elongated slots at both ends of the inverted U-shaped connecting and fixing part 102 are arranged in a cross shape, which allows the limiting bracket 1 to be adjusted in the front-back direction and the left-right direction.

[0068] In the above embodiments, the long slots of the limiting bracket 1 and the bracket 2 arranged in a cross shape and the long slot mounting hole at the rear end of the bracket 2 enable the support structure to accurately fix complex extended pipelines from six degrees of freedom: up, down, left, right, front, and back.

[0069] The above embodiments are all described using a hexagonal connection structure as an example. This application can also be configured as an octagonal connection structure or a circular connection structure, etc. This application does not make any specific limitations here.

[0070] In summary, the support structure for the extended pipeline provided in this application mainly includes a limiting bracket and a support bracket. Both the limiting bracket and the support bracket are adjusted and fixed via elongated slots, facilitating adaptation to the natural state of the extended pipeline and avoiding unnecessary external forces. The limiting bracket provides stable and reliable positioning, is easy to install, covers a wide range of installation conditions, and has a neat and aesthetically pleasing appearance. Since traditional terminal connections require two wrenches—one for fixing the valve seat and the other for installing the ferrule—the limiting bracket designed in this application can replace one wrench when fixing the terminal ball valve, enabling single-wrench operation and simplifying installation. The limiting bracket, used to fix terminal or secondary terminal ball valves, mimics the wrench shape and allows for limiting from multiple sides, simultaneously satisfying the limiting requirements for vertical, horizontal, and vertical freedom.

[0071] In this application, bracket 2 can meet the requirements using ordinary and compliant production methods, while limiting bracket 1 requires surface treatment to ensure its aesthetics. This support structure underwent 50 repeated installation and disassembly tests on the machine, demonstrating strong stability of the extended pipeline.
