Description

[Technical Field]

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

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (such as temperature, pressure, and flow rate) of the transported medium. When installing a valve, it needs to be supported first, then the center of the valve's flange sealing surface must be aligned with the center of the pipeline flange sealing surface, and then installed together to achieve a seal. For example, in the prior art, patent publication number CN116164149A discloses a high-temperature pipeline regulating system, including a support for mounting the valve body. A moving track is provided between the support and the valve body, and the moving track includes a pressure-bearing track and a guide track. The pressure-bearing track is located at the bottom of the transmission component to support its movement, and the guide tracks are located on both sides of the transmission component to guide its movement. The moving track moves the transmission component towards the pipeline side to facilitate its installation and ensure a tight seal between the flange sealing surface of the transmission component and the flange sealing surface of the pipeline. However, in this scheme, the moving track only moves along the central axis of the pipeline. In actual installation, one end of the pipeline may tilt in any direction, making it difficult for the two flange sealing surfaces to fit tightly together, thus failing to guarantee a seal and posing a safety hazard.

[0003] Therefore, it is necessary to provide a support device for valve installation to solve the above-mentioned technical problems. [Utility Model Content]

[0004] The main purpose of this utility model is to provide a support device for valve installation, which can adjust the position of the valve in the X, Y and Z directions, thereby adapting to pipelines in different positions and achieving precise docking between the valve and the pipeline.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a support device for valve installation, comprising a base plate, a support frame movably disposed on the base plate for supporting the valve, and a limiting module disposed at one end of the base plate for positioning the support frame. A pair of tracks are provided on the front and rear sides of the base plate along the X direction. The bottom of the support frame is movably disposed on the tracks via a plurality of rollers. An annular limiting part is provided on the outer side of the rollers to prevent the rollers from disengaging from the tracks. A floating gap is provided between the annular limiting part and the tracks to allow the rollers to float along the Y direction. The size of the floating gap is adjustable.

[0006] Furthermore, the support frame includes a movable base movably mounted on the base plate and a pair of triangular support frames arranged opposite each other above the movable base. A clearance space for placing the valve is formed between the pair of triangular support frames. Each of the triangular support frames has a mounting part at its top, and the valve's support part is mounted on the mounting part by a first bolt.

[0007] Furthermore, each of the triangular support frames is provided with a first connecting plate at its bottom, and a second connecting plate that cooperates with the first connecting plate is provided on the movable base. The first connecting plate and the second connecting plate are fixedly installed by a second bolt. Moreover, the first connecting plate and the second connecting plate are provided with stepped grooves on their opposite surfaces. The stepped grooves of the first connecting plate and the second connecting plate are arranged opposite each other and interlock with each other.

[0008] Furthermore, the movable base is provided with a plurality of support shafts extending along the Y direction on its front and rear sides, and bearings are sleeved on the outer periphery of the support shafts, and the rollers are rotatably mounted on the support shafts through the bearings.

[0009] Furthermore, a limiting ring is provided between the bearings to restrict the forward and backward movement of the bearings, and a first limiting buckle is provided at the outer end of the support shaft to prevent the bearings from moving. The roller is interference-fitted with the outer ring of the bearing, and a second limiting buckle is provided inside the roller to fasten onto the outer ring of the bearing.

[0010] Furthermore, the movable base is provided with a first mounting hole for mounting the support shaft, and second mounting holes are provided on both sides of the first mounting hole. A third bolt is provided in the second mounting hole to abut against the outer periphery of the support shaft and to assemble the support shaft with the movable base. The size of the floating gap can be adjusted by moving the support shaft back and forth.

[0011] Furthermore, the limiting module includes a mounting plate disposed on the base plate, a support frame mounted on the mounting plate with an X-direction position adjustable, and a limiting screw with one end disposed on the support frame and the other end disposed on the movable base.

[0012] Furthermore, the mounting plate is provided with a plurality of first positioning holes, and the bottom of the support frame is provided with a plurality of second positioning holes. A fourth bolt can be selectively provided in the first positioning holes and the second positioning holes to make the position of the support frame on the mounting plate adjustable.

[0013] Compared with existing technologies, the advantages of this utility model's support device for valve installation are as follows: The floating gap allows the roller to move along the Y-direction, and the roller, carrying the movable base, floats along the Y-direction, thus allowing the valve mounted on the triangular support frame to float along the Y-direction. This enables fine-tuning of the valve's position in the Y-direction, ensuring precise docking between the valve and the pipeline. Furthermore, the size of the floating gap is adjustable by adjusting the front and rear positions of the support shaft, accommodating different offsets during valve-pipe docking, thus offering good versatility. The fourth bolt, in conjunction with the first positioning hole at different positions, allows adjustment of the support frame's position along the X-direction, enabling the movable base to move along the X-direction, thereby allowing the valve to move along the X-direction. The height of the movable base can be adjusted by changing the diameter of the roller, thus adjusting the valve's height to accommodate pipelines at different heights. Therefore, this support device can adjust the valve's position in the X, Y, and Z directions, adapting to pipelines at different locations and achieving precise docking between the valve and the pipeline.

Detailed Implementation Methods

[0023] Please refer to Figures 1-3 This embodiment is a support device 100 for valve installation. The support device 100 for valve installation includes a base plate 1, a support frame 2 movably mounted on the base plate 1 for supporting the valve 200, and a limiting module 3 located at one end of the base plate 1 for positioning the support frame 2. A pair of rails 11 are provided on the front and rear sides of the base plate 1 along the X direction. The bottom of the support frame 2 is movably mounted on the rails 11 by a plurality of rollers 4.

[0024] In this example, mounting grooves 12 for mounting rails 11 are provided on the front and rear sides of the base plate 1. The mounting grooves 12 are adapted to the rails 11. By placing the rails 11 in the mounting grooves 12, the stability of the rails 11 can be guaranteed.

[0025] The valve 200 is cylindrical and is horizontally supported on the support frame 2 to facilitate the connection of the valve 200 with the pipeline. In order to facilitate the valve 200 to be conveniently supported on the support frame 2, the valve 200 includes a valve body 201 in the middle and support parts 202 provided on the front and rear sides of the valve body 201.

[0026] The support frame 2 includes a movable base 21 movably mounted on the base plate 1 and a pair of triangular support frames 22 arranged opposite each other above the movable base 21. A clearance space 5 for placing the valve 200 is formed between the pair of triangular support frames 22. Each of the triangular support frames 22 has a mounting part 221 at its top. The support part 202 of the valve 200 is mounted on the mounting part 221 by a first bolt. The triangular support frames 22 on the front and rear sides are fixedly connected by several support columns 23 to ensure the stability of the triangular support frames 22.

[0027] Since the inclined sides of the triangular support frame 22 tend to move to both sides, a first connecting plate 222 is provided at the bottom of the triangular support frame 22, and a second connecting plate 211 that cooperates with the first connecting plate 222 is provided on the movable base 21. The first connecting plate 222 and the second connecting plate 211 are fixedly installed by the second bolt. Moreover, the first connecting plate 222 and the second connecting plate 211 are provided with stepped grooves on their opposite surfaces. The stepped grooves of the first connecting plate 222 and the second connecting plate 211 are arranged opposite each other and interlock with each other. The interlocking of the stepped grooves can prevent the inclined sides of the triangular support frame 22 from moving to both sides.

[0028] The movable base 21 has several support shafts 212 extending along the Y direction on its front and rear sides. Bearings 213 are sleeved on the outer periphery of the support shafts 212, and the rollers 4 are rotatably mounted on the support shafts 212 through the bearings 213. A limiting ring 214 is provided between the bearings 213 to restrict the forward and backward movement of the bearings 213. A first limiting buckle 215 is provided at the outer end of the support shaft 212 to prevent the bearings 213 from moving. The first limiting buckle 215 restricts the forward and backward movement of the bearings 213 on the support shaft 212. The roller 4 is interference-fitted with the outer ring of the bearing 213. A second limiting buckle 216 is provided inside the roller 4 to lock onto the outer ring of the bearing 213. The second limiting buckle 216 restricts the forward and backward movement of the roller 4 on the bearing 213. The roller 4 is fixedly assembled with the outer ring of the bearing 213, so that the roller 4 can roll in the X direction on the track 11. When the roller 4 moves in the Y direction, it will move the support shaft 212 and the moving base 21 together in the Y direction. The height of the moving base 21 can be adjusted by changing the diameter of the roller 4, thereby adjusting the height of the valve 200 to adapt to pipes at different heights.

[0029] The outer side of the roller 4 is provided with an annular limiting part 41 to prevent the roller 4 from leaving the track 11. The annular limiting part 41 of the front roller 4 is restricted on the front track 11, and the annular limiting part 41 of the rear roller 4, which is arranged opposite to it, is restricted on the rear track 11. The two annular limiting parts 41 are restricted on the front and rear tracks 11, which can prevent the roller 4 from leaving the track in the Y direction.

[0030] A floating gap 6 is provided between the annular limiting part 41 and the track 11, which allows the roller 4 to float in the Y direction. The floating gap 6 allows the roller 4 to move in the Y direction, thereby moving the support shaft 212 and the movable base 21 together in the Y direction. When the valve 200 and the pipeline are relatively misaligned in the Y direction, the floating gap 6 allows the roller 4 to move in the Y direction, and the roller 4 floats in the Y direction along with the movable base 21. This allows the valve 200 mounted on the triangular support frame 22 to float in the Y direction, thereby allowing fine adjustment of the position of the valve 200 in the Y direction, so that the valve 200 can be accurately connected and installed with the pipeline.

[0031] The movable base 21 has a first mounting hole 217 for mounting the support shaft 212, and second mounting holes 218 on both sides of the first mounting hole 217. After the support shaft 212 is installed into the first mounting hole 217, third bolts are simultaneously screwed into the second mounting holes 218 on both sides. The third bolts on both sides simultaneously abut against the outer circumference of the support shaft 212, completing the installation and fixation of the support shaft 212 to the movable base 21. If the offset in the Y direction when the valve 200 is connected to the pipeline is large, the movable base 21 needs to move a large distance in the Y direction, so the floating gap 6 is also large. If the offset in the Y direction when the valve 200 is connected to the pipeline is small, the movable base 21 needs to move a small distance in the Y direction, so the floating gap 6 is also small. Therefore, the size of the floating gap 6 needs to be set to be adjustable to adapt to different offsets when the valve 200 is connected to the pipeline. The size of the floating gap 6 can be adjusted by adjusting the installation position of the support shaft 212 on the movable base 21. When it is necessary to adjust the size of the floating gap 6, the third bolt can be loosened, the support shaft 212 can be moved to the set position in the Y direction, and then the third bolt can be tightened again to complete the installation and fixation of the support shaft 212 and the movable base 21, thereby realizing the adjustment of the size of the floating gap 6.

[0032] The limiting module 3 includes a mounting plate 31 mounted on the base plate 1, a support frame 32 whose X-direction position is adjustable and mounted on the mounting plate 31, and a limiting screw 33 with one end mounted on the support frame 32 and the other end mounted on the movable base 21. At the position where the limiting screw 33 contacts the movable base 21, a first nut is screwed onto each of the limiting screws 33 on both sides of the movable base 21, and the limiting screw 33 is fixed to the movable base 21 by the first nut. At the position where the limiting screw 33 contacts the support frame 32, a second nut is screwed onto each of the limiting screws 33 on both sides of the support frame 32, and the limiting screw 33 is fixed to the support frame 32 by the second nut. When the support frame 32 and the limiting screw 33 are moved along the X-direction, the movable base 21 can be moved along the X-direction, thereby enabling the valve 200 to move along the X-direction.

[0033] The mounting plate 31 has several first positioning holes 311, and the bottom of the corresponding support frame 32 has several second positioning holes 321. A fourth bolt can be selectively installed in the first positioning holes 311 and the second positioning holes 321 to adjust the position of the support frame 32 on the mounting plate 31. If it is necessary to move the valve 200 in the X direction, the corresponding moving base 21 can be moved in the X direction. The fourth bolt is then loosened and reinserted into the corresponding first positioning hole 311. The position of the support frame 32 in the X direction is adjusted by the cooperation of the fourth bolt with the first positioning holes 311 at different positions, thus enabling the moving base 21 to move in the X direction, and consequently, the valve 200 to move in the X direction.

[0034] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
