Description

Technical Field

[0001] This utility model relates to the field of installation equipment technology, and in particular to a valve auxiliary installation device. Background Technology

[0002] Small gate valves are mainly used to cut off the flow of media in pipelines. Their working principle is to open and close the valve by raising and lowering the gate. Specifically, when the sealing surface of the gate and the valve seat is smooth and flat, the gate moves downward to prevent the media from flowing through; when the gate moves upward, the media can pass through freely.

[0003] Small gate valves are widely used in many fields, such as process modules, due to their advantages of low flow resistance, easy opening and closing, and simple structure. However, during the assembly of the upper cover plate of a process module, the small gate valves, due to their considerable weight, require one person to position them while another operates the clamps, resulting in low efficiency. Furthermore, after installation, the heights of the small gate valves corresponding to the two chambers of the process module cannot be adjusted simultaneously, making it difficult to ensure that the installation level of the two small gate valves is perfectly aligned. Utility Model Content

By turning the adjustment rod, the adjustment block can move away from or towards the inside of the second track.

[0013] In some embodiments, when there are two valves to be installed and both valves are located on a cover plate, one of the second rails can be engaged with one side of the cover plate and the other second rail can be engaged with the other side of the cover plate.

[0014] In some embodiments, the top of the support seat has a downwardly recessed support groove, the shape of which matches the shape of the bottom of the valve.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] This embodiment provides a valve auxiliary installation device, such as... Figure 1-8 As shown, the valve auxiliary installation device includes a support seat 1, a lifting unit 2, and a support unit 3. One end of the support seat 1 is used to support the valve, and the other end of the support seat 1 has a mating port 11. The top of the lifting unit 2 is located inside the mating port 11, and it can drive the support seat 1 to move up and down to adjust the height of the support seat 1. The bottom of the lifting unit 2 is set on the support unit 3.

[0035] The support seat 1 is used to support the valve, potentially reducing the need for manual lifting. The lifting unit 2 can adjust the height of the support seat by moving it up and down, solving the height adjustment problem. Furthermore, when there are two valves, it can ensure that both valves are at the same height. The support unit 3 supports the entire device, maintaining stability and allowing valve installation to be performed by a single person. In addition, the support unit 3 has other functions, which will be described in other embodiments. The mating port 11 on the support seat 1 connects the lifting unit 2 and the support seat 1, enabling the lifting unit 2 to drive the support seat 1 to move up and down. The mating port 11 also ensures accurate lifting and lowering movements, improving the precision of height adjustment.

[0036] During installation, the valve is placed on the support seat 1 and adjusted to the target height using the lifting unit 2; positioning can be completed by a single person. The support unit 3 keeps the device stable, and the precise control of the lifting unit 2 ensures that the level of the two valves is consistent through fine-tuning, eliminating the need for multiple people to work together. In other words, the support seat 1 supports the valve and transmits the lifting force; its mating port 11 connects to the top of the lifting unit 2, forming a transmission interface for height adjustment. The lifting unit 2 achieves vertical displacement of the support seat 1 through a mechanical lifting mechanism, allowing precise control of the valve installation height and solving the problem of difficulty in manually adjusting the level. The support unit 3 provides a stable base, ensuring that the device does not shift during operation, making single-person operation possible.

[0037] In a specific embodiment, the lifting unit 2 includes a mating block 21 and a mating nut 22. The top of the mating block 21 is located inside the mating opening 11. One side of the mating block 21 has a first tooth 23. One end of the mating nut 22 is inserted into the outer wall of the mating opening 11, and this end has a second tooth 24 that meshes with the first tooth 23. By operating the other end of the mating nut 22, the first tooth 23 and the second tooth 24 engage to move the lifting seat 1 up and down.

[0038] The top of the mating block 21 is embedded inside the mating opening 11 of the lifting seat 1, and its bottom is connected to the support structure of the lifting unit 2. A first tooth 23 is provided on one side of the mating block, and this tooth surface meshes with the second tooth 24 at the end of the mating nut 22. The mating block 21 is the core transmission component for the lifting motion. After its tooth surface meshes with the second tooth 24 of the mating nut 22, it converts the rotational motion of the mating nut 22 into its own vertical linear motion, thereby driving the lifting seat 1 to move up and down. Furthermore, the first tooth 23 of the mating block 21 can be designed as a helical tooth or a trapezoidal tooth to enhance meshing stability and prevent slippage during movement.

[0039] One end of the mating nut 22 is inserted into the outer wall of the mating opening 11, and its end is machined with a second tooth 24 that meshes with the first tooth 23 of the mating block; the other end is exposed for manual or tool-driven rotation by the operator. The mating nut 22 converts rotational torque into linear thrust by rotating to drive the second tooth 24 to mesh with the first tooth 23.

[0040] When the operator rotates the mating nut 22, the second tooth 24 pushes the first tooth 23 to slide along the tooth surface. Since the mating block 21 is confined within the mating opening 11, the meshing motion of the teeth forces the mating block to move vertically, thereby causing the lifting seat 1 to rise and fall. In the specific process, rotating the mating nut 22 clockwise causes the second tooth 24 to push the mating block 21 upward through meshing, and the lifting seat 1 is raised accordingly, realizing valve height adjustment; rotating the mating nut 22 counterclockwise causes the mating block 21 to move downward under the action of gravity or external load, and the meshing of the teeth provides controllable downward resistance to prevent sudden drop.

[0041] The mating block 21 and the mating nut 22 convert the rotational motion into linear lifting through tooth meshing, which solves the technical problems of traditional installation requiring multiple people to cooperate and difficulty in leveling.

[0042] In a specific embodiment, the lifting unit 2 further includes a locking member 25. One end of the locking member 25 is inserted into the outer wall of the mating opening 11 and faces the mating block 21 inside the mating opening 11. The locking member 25 can move along the wall thickness direction of the mating opening 11 to fix or release the mating block 21. The locking member 25 is located on the outer wall of the mating opening 11, with one end inserted into the outer wall and facing the mating block 21 inside the mating opening. The locking member 25 can directly contact the mating block 21, and fix or release the mating block 21 by moving along the wall thickness direction of the mating opening 11. In a specific embodiment, the locking member 25 can be a threaded bolt, which presses the mating block 21 by screwing into the threaded hole on the outer wall, using friction to fix the position. Its thread can be designed as a trapezoidal thread to provide a self-locking function, ensuring that the position of the lifting seat 1 is stable after lifting and lowering, and avoiding accidental slippage due to load weight.

[0043] Once the lifting seat 1 is adjusted to the target height by the lifting unit 2, the locking member 25 can prevent accidental displacement caused by external force or vibration by pressing the mating block 21, thereby maintaining the stable height of the lifting seat. During the height adjustment process, if it is necessary to temporarily fix the position of the mating block 21, the locking member 25 can quickly lock to avoid safety hazards caused by the sliding of the mating block during operation. In addition, the locking member 25 cooperates with the first tooth 23 and the second tooth 24 of the lifting unit 2 to achieve quick locking after the height adjustment is completed, improving the overall reliability of the device.

[0044] In a specific embodiment, the support unit 3 includes a first track 31 and a second track 32. The mating block 21 is slidably disposed on the first track 31. The two ends of the first track 31 are respectively provided with the second track 32. The first track 31 can slide along the second track 32. The directions of the first track 31 and the second track 32 are different.

[0045] The first track 31 and the second track 32 are designed to be perpendicular to each other. Specifically, the first track 31 is a horizontal track (X-axis direction) used to enable the mating block 21 to slide laterally in the horizontal plane; the second track 32 is a vertical track (Y-axis direction) located at both ends of the first track 31, allowing the first track 31 to move longitudinally as a whole. The perpendicular intersection of the first track 31 and the second track 32 forms a two-dimensional planar adjustment system. Through the combined movement of the horizontal (X-axis) and vertical (Y-axis) directions, the mating block 21 can meet the adjustment requirements of any position in the horizontal plane.

[0046] During operation, the first track 31 slides along the second track 32. By moving the first track 31 longitudinally, the position of the support seat 1 in the Y-axis direction can be adjusted. The mating block 21 slides along the first track 31. By moving the mating block 21 laterally, the position of the support seat 1 in the X-axis direction can be adjusted. This satisfies the horizontal alignment requirements of the small gate valves between the process module cavities.

[0047] In this embodiment, the first track 31 and the second track 32 work together with the lifting unit 2 to enable a single person to complete the horizontal positioning and height adjustment of the valve without the need for multiple people to cooperate.

[0048] In a specific embodiment, the bottom of the mating block 21 has a sliding seat 26, the bottom of the sliding seat 26 has a groove 27, and the groove 27 mates with the first track 31.

[0049] The sliding seat 26 is located at the bottom of the mating block 21. As an intermediate component connecting the mating block 21 and the first track 31, its function is to convert the up-and-down movement of the mating block 21 into horizontal sliding along the track, while also providing support and guidance. The groove 27 is located at the bottom of the sliding seat 26 and its shape matches the first track 31. The groove 27 is directly embedded in the first track 31, and the sliding seat 26 can move stably on the first track 31 through mechanical engagement.

[0050] In this embodiment, the sliding seat 26 engages with the first track 31 via the groove 27, ensuring that the mating block 21 slides stably along the track and preventing offset or wobbling. The shape matching between the groove 27 and the first track 31 (such as a T-slot, dovetail groove, etc.) prevents the sliding seat from disengaging from the track, ensuring the safety of the device. At the same time, the shape of the groove 27 restricts the sliding direction, ensuring the linear movement of the mating block 21 during adjustment and avoiding installation errors caused by offset.

[0051] In a specific embodiment, the first track 31 includes a crossbar 311, the two ends of which are bent downward to form a first vertical bar 312 and a second vertical bar 313, respectively. The end of the first vertical bar 312 has a first connecting groove 314 opening toward the second vertical bar 313, and the end of the second vertical bar 313 has a second connecting groove 315 opening toward the first vertical bar 312. One of the second tracks 32 is slidably disposed in the first connecting groove 314, and the other second track 32 is slidably disposed in the second connecting groove 315.

[0052] The crossbar 311, as the main body of the first track 31, supports the groove 27 of the sliding seat 26, providing a horizontal sliding track for the mating block 21. Its downward-bent ends achieve a rigid connection with the vertical bar, forming an overall support frame. The first vertical bar 312 and the second vertical bar 313 are formed by downward bending at both ends of the crossbar 311, and are slidably connected to the second track 32 via the first connecting groove 314 and the second connecting groove 315, respectively. The first connecting groove 314 and the second connecting groove 315 are located at the ends of the first vertical bar 312 and the second vertical bar 313, respectively, with their opening directions facing each other. Their function is to accommodate the ends of the second track 32, forming a sliding pair; to restrict the movement direction of the second track 32, ensuring that the first track 31 slides linearly along the second track 32; and to achieve overall telescopic adjustment of the support unit through the cooperation of the grooves and the track.

[0053] In the specific operation, when the horizontal installation position of the small gate valve needs to be adjusted, the operator pushes the first rail 31 to slide along the second rail 32. At this time, the first vertical rod 312 and the second vertical rod 313 cooperate with the second rail 32 through the first connecting groove 314 and the second connecting groove 315, realizing the horizontal movement of the entire lifting seat 1 driven by the horizontal rod 311. During the sliding process, the groove 27 of the sliding seat 26 slides smoothly along the surface of the horizontal rod 311, ensuring that the horizontal position of the mating block 21 is accurately adjusted. When height adjustment is required, in the lifting unit 2, the second tooth 24 is engaged with the first tooth 23 of the mating block 21 by rotating the mating nut 22, driving the lifting seat 1 to move up and down. At this time, the rigid frame composed of the horizontal rod 311, the first vertical rod 312, the second vertical rod 313, the first connecting groove 314 and the second connecting groove 315 provides stable vertical guidance for the lifting action and prevents the lifting seat from tilting. After the position adjustment is completed, the locking part 25 is inserted into the outer wall of the mating port 11 and presses against the mating block 21. At the same time, the friction of the first connecting groove 314, the second connecting groove 315 and the second track 32 together locks the position of the first track 31, forming a double fixing mechanism to ensure the stability of the device during installation.

[0054] In a specific embodiment, the support unit 3 further includes an adjustment module 33 for adjusting the distance between the two second tracks 32; the adjustment module 33 is disposed on one of the second tracks 32 and / or the other second track 32. The adjustment module 33 is used to adjust the distance between the two second tracks 32, thereby adjusting the overall width of the support unit 3 to adapt to the size requirements of different installation environments or process modules.

[0055] In a specific embodiment, the adjustment module 33 includes an adjustment rod 331 and an adjustment block 332. The adjustment block 332 is located inside the second track 32. The adjustment rod 331 passes through the second track 32 from the outside and is connected to the adjustment block 332. By turning the adjustment rod 331, the adjustment block 332 can move away from or closer to the inside of the second track 32.

[0056] The adjusting rod 331 is typically a screw structure with external threads. When the adjusting rod 331 is turned, its threads engage with the internal threads of the adjusting block 332, converting rotational motion into linear motion. The adjusting block 332 is fixed inside the second track 32 and has a threaded hole inside that matches the adjusting rod 331. When the adjusting rod 331 rotates, the adjusting block 332 moves along the inner wall of the second track 32 in a direction away from or towards the track center. For example, rotating the adjusting rod 331 clockwise moves the adjusting block 332 outward, increasing the distance between the two second tracks 32; rotating the adjusting rod 331 counterclockwise moves the adjusting block 332 inward, decreasing the distance between the two second tracks 32.

[0057] In a specific embodiment, when there are two valves to be installed, and both valves are located on a cover plate, one of the second rails 32 can be engaged with one side of the cover plate, and the other second rail 32 can be engaged with the other side of the cover plate. First, one of the second rails 32 of the auxiliary device is engaged with one side of the cover plate, and then the other second rail 32 is engaged with the other side of the cover plate by adjusting the module 33; the small gate valve (i.e., the valve) is placed on the support seat 1 according to the installation direction, and then the height is adjusted to a suitable position.

[0058] In a specific embodiment, the top of the support seat 1 has a downwardly recessed support groove 12, the shape of which matches the shape of the bottom of the valve. The downwardly recessed shape of the support groove 12 precisely matches the bottom of the valve, effectively supporting and fixing the small gate valve, preventing it from sliding or shifting during installation, and ensuring positioning accuracy.

[0059] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
