Description

Technical Field

[0001] This utility model relates to the field of valve connection technology, and more specifically, to a combinable valve connection bracket. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. For valves used with high-temperature fluid media, a connecting bracket is required to connect the valve and its actuator (electric or pneumatic actuator). The connecting bracket not only serves a fixing function but also keeps the actuator away from the valve, thus protecting the actuator from high temperatures.

[0003] In the same piping system, the fluid temperature varies at different locations, and the corresponding distances between the valves and the actuators should also differ. Existing valve mounting brackets are typically single components, designed based on the required height difference between the actuator and the valve. Therefore, multiple mounting brackets are required, and these brackets are not interchangeable and can only be used once. Utility Model Content

[0004] In view of this, the present invention proposes a combinable valve connection bracket to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model proposes a combinable valve connecting frame, including an upper connecting frame and multiple lower connecting frames;

[0006] The upper connecting frame has an actuator connecting part at the top for connecting the actuator; the upper connecting frame has a first extended connecting part at the bottom for connecting to the top of the lower connecting frame below it.

[0007] The top of the lower connecting frame has a second extended connecting part, which is adapted to the first extended connecting part and is used to connect to the bottom of the upper connecting frame;

[0008] The bottom of the lower connecting frame has a third extended connecting part, which is adapted to the second extended connecting part for connecting to the top of another lower connecting frame below it, or for connecting a valve.

[0009] In one embodiment, the upper connecting frame includes a frame body, which is a cylindrical structure;

[0010] The first extension connection includes a stepped hole disposed inside the frame body, the stepped hole penetrating the frame body, the central axis of the stepped hole being parallel to the central axis of the frame body, and the stepped hole being used for fixing with a first bolt to connect the lower connecting frame.

[0011] In one embodiment, at least two stepped holes are provided; each stepped hole is provided at equal intervals along the circumference of the frame.

[0012] In one embodiment, the second extended connection includes a threaded hole disposed on the top of the lower connecting frame, the central axis of the threaded hole being parallel to the central axis of the lower connecting frame, the position of the threaded hole corresponding to the position of the stepped hole, and the threaded hole being used to connect with the threaded section of the first bolt.

[0013] In one embodiment, at least two threaded holes are provided; each threaded hole is equally spaced along the circumference of the lower connecting frame.

[0014] In one embodiment, the third extended connection includes a second through hole disposed at the bottom of the lower connecting frame, the central axis of the second through hole being parallel to the central axis of the lower connecting frame, the position of the second through hole corresponding to the position of the threaded hole, and the second through hole being used for fixing with a second bolt to connect to another lower connecting frame or the valve below it.

[0015] In one embodiment, at least two second through holes are provided; each of the second through holes is provided at equal intervals along the circumference of the lower connecting frame.

[0016] In one embodiment, the lower connecting frame includes a first plate, a second plate, and a plurality of columns. The first plate is disposed below the second plate, and the columns are disposed between the first plate and the second plate. The two ends of the columns are fixedly connected to the first plate and the second plate, respectively.

[0017] The second plate has a through-hole in the middle, and the bottom of the frame has a first boss that is adapted to the through-hole.

[0018] In one embodiment, the bottom of the first plate has a second protrusion that is adapted to the snap-fit ​​hole.

[0020] The bottom of the frame has a first chamfer;

[0021] The frame has a clearance hole, a first through hole, and a second through hole arranged sequentially in the middle.

[0022] The actuator connection part is a flange structure, and the edge of the actuator connection part has a plurality of first through holes, which are used for third bolts to fix and connect the actuator.

[0023] Compared with existing technologies, the advantages of this modular valve connector bracket lie in its combination design of an upper connector bracket (with an actuator connection part) and multiple lower connector brackets (with mutually adaptable extension connections). Users can flexibly stack the lower connector brackets according to actual height requirements. This design eliminates the need for custom-designed connector brackets for each scenario, achieving a modular solution of "one set of components for multiple heights."

Detailed Implementation

[0034] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Reference Figure 1 and Figure 2 This embodiment proposes a combinable valve connecting frame, including an upper connecting frame and multiple lower connecting frames; the top of the upper connecting frame has an actuator connecting part 12 for connecting an actuator; the bottom of the upper connecting frame has a first extended connecting part for connecting to the top of the lower connecting frame below it; the top of the lower connecting frame has a second extended connecting part, which is adapted to the first extended connecting part for connecting to the bottom of the upper connecting frame; the bottom of the lower connecting frame has a third extended connecting part, which is adapted to the second extended connecting part for connecting to the top of another lower connecting frame below it, or for connecting a valve.

[0036] Existing valve connectors are single components, requiring individual design and manufacturing for each specific height difference (caused by fluid temperature variations at different locations within the piping system). This results in non-interchangeable connectors, limiting their use to single-use and increasing design and production costs. The above embodiment, through a combination design of an upper connector (with an actuator connection) and multiple lower connectors (with mutually adaptable extension connections), allows users to flexibly stack the lower connectors according to actual height requirements. For example: Refer to... Figure 7 and Figure 8 If the drive unit needs to be positioned further away from high-temperature valves (e.g., in high-temperature areas), multiple lower connecting brackets can be added; refer to... Figure 6Conversely, in low-temperature regions, the number of lower connecting brackets can be reduced. This configuration eliminates the need for custom-designed connecting brackets for each scenario, achieving a modular solution of "one set of components for multiple heights." This embodiment significantly reduces the number of design iterations, avoids the repeated manufacturing of connecting brackets of different heights, improves resource utilization, solves the problem of height customization, and achieves height adjustability.

[0037] When the fluid temperature in the piping system changes (e.g., valve relocation), users can easily add or remove the lower connector module for rapid height adjustment without replacing the entire unit. All connectors use adaptable interfaces (such as threaded, snap-fit, or flanged designs) for easy assembly and disassembly. The lower connector can be reused in different valve installations, extending component life. This embodiment improves the overall adaptability of the valve system, especially suitable for complex piping systems with large temperature gradients (such as petrochemical or energy systems).

[0038] In some embodiments, the upper connecting frame includes a frame 11, which is a cylindrical structure; the first extended connecting part includes a stepped hole 14 disposed inside the frame 11, the stepped hole 14 penetrates the frame 11, allowing the first bolt to pass through and fix from top to bottom, and the operating space only needs to be on one side (top), solving the problem of difficult installation of bottom bolts in narrow spaces.

[0039] The central axis of the stepped hole 14 is parallel to the central axis of the frame 11. The stepped hole 14 is used for the first bolt to fix and connect the lower connecting frame. The parallelism between the central axis of the stepped hole and the central axis of the frame ensures that the bolt is subjected to vertical force and prevents the connection from loosening due to eccentric load. The large diameter section of the stepped hole accommodates the bolt head, while the small diameter section constrains the screw, forming a two-level force-bearing surface (bolt head pressing against the stepped surface + screw subjected to shear force), which improves the shear strength compared to the through hole structure.

[0040] In some embodiments, at least two stepped holes 14 are provided; each stepped hole 14 is provided at equal intervals along the circumference of the frame 11.

[0041] In some embodiments, refer to Figure 4 The second extended connection includes a threaded hole 24 disposed on the top of the lower connecting frame. The central axis of the threaded hole 24 is parallel to the central axis of the lower connecting frame. The position of the threaded hole 24 corresponds to the position of the stepped hole 14. The threaded hole 24 is used to connect with the threaded section of the first bolt.

[0042] In some embodiments, at least two threaded holes 24 are provided; each threaded hole 24 is provided at equal intervals along the circumference of the lower connecting bracket.

[0043] In some embodiments, refer to Figure 5The third extended connection includes a second through hole 26 located at the bottom of the lower connecting frame. The central axis of the second through hole 26 is parallel to the central axis of the lower connecting frame. The position of the second through hole 26 corresponds to the position of the threaded hole 24. The central axis of the threaded hole 24 is parallel to the central axis of the lower connecting frame and its position strictly corresponds to the stepped hole 14, forming a self-aligning mechanism. The second through hole 26 is used for fixing with a second bolt to connect to another lower connecting frame or valve below it. When disassembling a certain lower connecting frame, only a single bolt needs to be loosened to separate that layer.

[0044] In some embodiments, at least two second through holes 26 are provided; each second through hole 26 is provided at equal intervals along the circumference of the lower connecting frame.

[0045] In some embodiments, refer to Figure 3 The lower connecting frame includes a first plate 21, a second plate 22, and multiple columns 23. The first plate 21 is located below the second plate 22, and the columns 23 are located between the first plate 21 and the second plate 22. The two ends of the columns 23 are fixedly connected to the first plate 21 and the second plate 22, respectively. The columns 23 serve as vertical supports, axially transmitting the load of the actuator to the valve and preventing the plates from bending. The double-plate design forms a shear-resistant plane, reducing weight by more than 50% compared to a solid block. The first plate 21 has a third through hole 28 in the middle, which further reduces weight.

[0046] The second plate 22 has a through-hole 25 in the middle, and the bottom of the frame 11 has a first boss 18. The first boss 18 is adapted to the 25 and is embedded in the 25. The gap can be ≤0.5mm and the horizontal offset is automatically corrected. The stepped hole 14 and the threaded hole 24 are naturally aligned due to coaxial constraint, and the bolt can be directly screwed in.

[0047] In some embodiments, the bottom of the first plate 21 has a second protrusion 27, which is adapted to the snap-fit ​​hole 25. The second protrusion 27 is embedded in the snap-fit ​​hole 25 to automatically correct the horizontal offset.

[0048] In some embodiments, the top of the snap-fit ​​hole 25 has a second chamfer 29; the second chamfer 29 allows for smooth insertion even with initial angular deviation.

[0049] The bottom of the frame 11 has a first chamfer 19; the middle part of the frame 11 has a clearance hole 15, a first through hole 16 and a second through hole 17 arranged in sequence; each through hole can reduce weight and facilitate wiring.

[0050] The actuator connection part 12 is a flange structure. The edge of the actuator connection part 12 has multiple first through holes 13. The first through holes 13 are used for third bolts to fix and connect the actuator. The first through holes 13 are arranged in a standard flange hole spacing matrix. When disassembling the actuator, only the third bolts need to be loosened, without removing the entire connection frame.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
