Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an auxiliary mounting bracket for a vacuum fine-tuning valve. Background Technology

[0002] Vacuum fine-tuning valves are used to fill vacuum systems with gas and precisely adjust the intake flow rate to control and regulate the vacuum level within the system. They are suitable for working media such as air free of particulate matter and non-corrosive gases. Vacuum fine-tuning valves are widely used in industries such as petroleum, natural gas, nuclear power, power plants, shipbuilding, metallurgy, heavy machinery, and research institutes. In short, vacuum fine-tuning valves have a very wide range of applications and are applicable to a particularly broad range of situations.

[0003] Some existing vacuum fine-tuning valves are large in size and weight. During installation, relying solely on manual support or simple hoisting equipment can easily lead to shaking and instability. This can not only affect the installation accuracy but also cause poor sealing and even safety accidents. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an auxiliary mounting bracket for a vacuum fine-tuning valve, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a vacuum fine-tuning valve auxiliary mounting bracket, including a fine-tuning valve body and a connecting column. Four sets of symmetrically distributed guide columns are fixedly installed on one end of the fine-tuning valve body near the connecting column. A bracket assembly is provided on one side of the fine-tuning valve body near the connecting column. A fixing seat is fixedly installed on one end of the bracket assembly away from the fine-tuning valve body. A locking assembly is fixedly installed on the inner side of the fixing seat.

[0006] The bracket assembly includes a fixed plate and a movable plate, and the fixed plate has a mounting hole at one end near the fine-tuning valve body.

[0007] Preferably, the bracket assembly further includes a handwheel, an adjusting screw, a limiting block, a guide rod, a second limiting block, and a through hole. The fixed plate is provided with a handwheel on the side near the fine-tuning valve body. An adjusting screw is fixedly installed at the end of the handwheel near the fixed plate. A limiting block is fixedly installed at the end of the adjusting screw away from the handwheel. A guide rod is fixedly installed at the end of the fixed plate near the moving plate. A second limiting block is fixedly installed at the end of the guide rod near the moving plate. A through hole is provided at the center of the ends of the fixed plate and the moving plate away from the fine-tuning valve body.

[0008] The above technical solution facilitates quick installation of the fine-tuning valve body by setting up a bracket assembly. The distance between the fixed plate and the moving plate can be manually adjusted to meet the distance requirements between the fine-tuning valve body and the connecting valve in different installation scenarios, thus improving the versatility of the bracket.

[0009] Preferably, the inner diameter of the through hole is the same as the outer diameter of the connecting column, the mounting hole and the guide column are slidably connected, and a locking nut that is threadedly connected to the guide column is provided on the side of the mounting hole away from the fine-tuning valve body.

[0010] With the above technical solution, the mounting hole and guide post are designed to slide together. When installing the bracket assembly, the mounting hole can be aligned with the guide post and inserted first to achieve initial positioning and installation of the bracket assembly and the fine-tuning valve body, reducing installation difficulty. Then, by tightening the lock nut and threaded connection with the guide post, the bracket assembly and the fine-tuning valve body can be quickly fixed. It also facilitates the quick disassembly of the bracket assembly and the fine-tuning valve body. The inner diameter of the through hole is the same as the outer diameter of the connecting post, which facilitates the quick connection of the fixed plate and the moving plate with the fine-tuning valve body, and also facilitates the tight fit with the connecting post, improving the stability of the connection between the connecting post and the connecting valve.

[0011] Preferably, the adjusting screw is connected through the movable plate, and the adjusting screw and the guide rod are symmetrically distributed about the center lines of the fixed plate and the movable plate, and the guide rod is slidably connected to the movable plate.

[0012] With the above technical solution, by adjusting the screw threaded to the moving plate and the guide rod slidingly connected to the moving plate, the operator can manually turn the handwheel to move the moving plate, thereby adjusting the length of the bracket assembly. This facilitates the installation of the fine-tuning valve body in different installation environments and improves installation efficiency.

[0013] Preferably, the locking assembly includes a lower pressure ring and an upper pressure ring, one end of the lower pressure ring and the upper pressure ring are rotatably connected, and the other end of the lower pressure ring and the upper pressure ring are provided with a rotating rod. The top of the rotating rod is threadedly connected to a locking block. A second handwheel is provided on the side of the upper pressure ring away from the lower pressure ring. An adjusting screw is fixedly installed on the end of the second handwheel near the upper pressure ring, and a pressing block is rotatably installed on the end of the adjusting screw away from the second handwheel.

[0014] The above technical solution includes a locking assembly. By rotatably connecting one end of the lower pressure ring and the upper pressure ring, and threadedly connecting the other end to the locking block via a rotating rod, the locking assembly can be opened and closed quickly and locked, facilitating rapid fixation to the connecting pipe and improving installation efficiency.

[0015] Preferably, the locking components are provided in two identical sets, and the two sets of locking components are symmetrically distributed on the center line of the support assembly. The second handwheel, the second adjusting screw, and the pressing block are also provided in two identical sets, and the two sets of handwheels, the second adjusting screw, and the pressing block are symmetrically distributed on the center lines of the lower pressure ring and the upper pressure ring.

[0016] The above technical solution, by setting two sets of symmetrically distributed locking components, facilitates the stable connection of the bracket assembly with the connecting pipe, improves the stability of the fine-tuning valve body installation, and, through the two sets of symmetrically distributed handwheels, adjusting screws, and pressing blocks, when the worker installs the lower and upper pressure rings on the outside of the connecting pipe, if the inner diameter of the lower and upper pressure rings is larger than the outer diameter of the connecting pipe, the worker can manually rotate handwheels, causing adjusting screws to rotate and thus moving the pressing blocks towards the connecting pipe. By simultaneously pressing inward from both sides until they are tightly fitted with the connecting pipe, the locking components can be quickly fixed.

[0017] Preferably, the extrusion block is made of rubber, and the cross-section of the extrusion block has a “︵” shape.

[0018] The above technical solution uses rubber as the material for the extrusion block, which has good elasticity and wear resistance. The cross-section of the extrusion block is shaped like a "︵", which allows it to better fit the surface of the connecting pipe during the extrusion process, increasing the contact area, thereby improving friction, enhancing the locking effect, and ensuring the stability of the fine-tuning valve body during operation.

[0019] Compared with the prior art, this utility model provides an auxiliary mounting bracket for a vacuum fine-tuning valve, which has the following advantages:

[0020] 1. This vacuum fine-tuning valve auxiliary mounting bracket has a sliding connection between the mounting hole and the guide column. By aligning the mounting hole with the guide column and inserting it, the bracket assembly and the fine-tuning valve body can be quickly positioned and installed. Through the design of adjusting screw threaded to the moving plate and guide rod slidingly connected to the moving plate, the operator can manually turn the handwheel to move the moving plate laterally, thereby adjusting the length of the bracket assembly. This meets the distance requirements between the fine-tuning valve body and the connecting pipe in different installation scenarios, improving the versatility of the bracket.

[0021] 2. The auxiliary mounting bracket for this vacuum fine-tuning valve is rotatably connected at one end of the lower pressure ring and the upper pressure ring, and the other end is threadedly connected to the locking block via a rotating rod. This facilitates the quick opening and closing of the locking assembly and its locking. With handwheels symmetrically distributed at both ends of the lower and upper pressure rings, adjusting screws, and a pressing block, when the inner diameter of the lower and upper pressure rings is larger than the outer diameter of the connecting pipe, the operator can manually rotate the handwheels on both sides. This causes the adjusting screws to rotate, thereby moving the pressing block towards the connecting pipe until the pressing block is tightly fitted to the connecting pipe, achieving rapid fixation of the locking assembly to the connecting pipe. This facilitates the connection of pipes with different diameters. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-6 As shown, the present invention provides an auxiliary mounting bracket for a vacuum fine-tuning valve, including a fine-tuning valve body 1 and a connecting column 2. Four sets of symmetrically distributed guide columns 3 are fixedly installed on one end of the fine-tuning valve body 1 near the connecting column 2. A bracket assembly 4 is provided on one side of the fine-tuning valve body 1 near the connecting column 2. A fixing seat 5 is fixedly installed on one end of the bracket assembly 4 away from the fine-tuning valve body 1. A locking assembly 6 is fixedly installed on the inner side of the fixing seat 5.

[0031] The bracket assembly 4 includes a fixed plate 401 and a movable plate 402. The fixed plate 401 has a mounting hole 403 at one end near the fine-tuning valve body 1.

[0032] Specifically, the bracket assembly 4 also includes a handwheel 405, an adjusting screw 406, a limiting block 407, a guide rod 408, a limiting block 409, and a through hole 410. The fixed plate 401 is provided with a handwheel 405 on the side near the fine-tuning valve body 1. The adjusting screw 406 is fixedly installed at the end of the handwheel 405 near the fixed plate 401. The limiting block 407 is fixedly installed at the end of the adjusting screw 406 away from the handwheel 405. The guide rod 408 is fixedly installed at the end of the fixed plate 401 near the moving plate 402. The limiting block 409 is fixedly installed at the end of the guide rod 408 near the moving plate 402. A through hole 410 is provided in the center of the ends of the fixed plate 401 and the moving plate 402 away from the fine-tuning valve body 1. The advantage is that by setting the bracket assembly 4, it is easy to quickly install with the fine-tuning valve body 1, and the distance between the fixed plate 401 and the movable plate 402 can be manually adjusted to meet the requirements of the distance between the fine-tuning valve body 1 and the connecting valve in different installation scenarios, thus improving the versatility of the bracket.

[0033] Specifically, the inner diameter of the through hole 410 is the same as the outer diameter of the connecting column 2. The mounting hole 403 is slidably connected to the guide column 3. A locking nut 404, threadedly connected to the guide column 3, is provided on the side of the mounting hole 403 away from the fine-tuning valve body 1. The advantage is that, by slidingly connecting the mounting hole 403 to the guide column 3, when installing the bracket assembly 4, the mounting hole 403 can be aligned with the guide column 3 and inserted first, achieving initial positioning and installation of the bracket assembly 4 and the fine-tuning valve body 1, reducing installation difficulty. Subsequently, the threaded connection between the locking nut 404 and the guide column 3 enables quick fixation of the bracket assembly 4 and the fine-tuning valve body 1, and also facilitates quick disassembly of the bracket assembly 4 and the fine-tuning valve body 1. The fact that the inner diameter of the through hole 410 is the same as the outer diameter of the connecting column 2 facilitates quick connection between the fixing plate 401 and the moving plate 402 and the fine-tuning valve body 1, and also facilitates tight fit with the connecting column 2, improving the stability of the connection between the connecting column 2 and the connecting valve.

[0034] Specifically, adjusting screw 406 is threaded through and connected to movable plate 402. Adjusting screw 406 and guide rod 408 are symmetrically distributed about the center lines of fixed plate 401 and movable plate 402, respectively. Guide rod 408 is slidably connected to movable plate 402. The advantage is that, through the design of adjusting screw 406 being threadedly connected to movable plate 402 and guide rod 408 being slidably connected to movable plate 402, operators can manually rotate handwheel 405 to move movable plate 402, thereby adjusting the length of bracket assembly 4. This facilitates the installation of fine-tuning valve body 1 in different installation environments and improves installation efficiency.

[0035] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, the locking assembly 6 includes a lower pressure ring 601 and an upper pressure ring 602. One end of the lower pressure ring 601 and the upper pressure ring 602 are rotatably connected, and the other end of the lower pressure ring 601 and the upper pressure ring 602 are provided with a rotating rod 603. The top of the rotating rod 603 is threadedly connected to a locking block 604. A second handwheel 605 is provided on the side of the upper pressure ring 602 away from the lower pressure ring 601. An adjusting screw 606 is fixedly installed on the end of the second handwheel 605 near the upper pressure ring 602, and a pressing block 607 is rotatably installed on the end of the adjusting screw 606 away from the second handwheel 605. The advantage is that by setting up the locking assembly 6, and by setting one end of the lower pressure ring 601 and the upper pressure ring 602 to be rotatably connected, and the other end to the locking block 604 through the rotating rod 603, the locking assembly 6 can be quickly opened, closed, and locked, which facilitates quick fixation to the connecting pipe and improves installation efficiency.

[0037] Specifically, there are two identical sets of locking components 6, which are symmetrically distributed along the center line of the bracket assembly 4. There are also two identical sets of handwheels 605, adjusting screws 606, and pressing blocks 607, which are symmetrically distributed along the center lines of the lower pressure ring 601 and the upper pressure ring 602. The advantage is that by setting two sets of symmetrically distributed locking components 6, the bracket assembly 4 can be stably connected to the connecting pipe, improving the stability of the installation of the fine-tuning valve body 1. Through two sets of symmetrically distributed handwheels 605, adjusting screws 606, and pressing blocks 607, when the operator installs the lower pressure ring 601 and the upper pressure ring 602 on the outside of the connecting pipe, if the inner diameter of the lower pressure ring 601 and the upper pressure ring 602 is larger than the outer diameter of the connecting pipe, the operator can manually turn the handwheel 605, causing the adjusting screw 606 to rotate, thereby driving the pressing block 607 to move towards the connecting pipe. By pressing inward from both sides simultaneously until it is tightly fitted with the connecting pipe, the locking component 6 can be quickly fixed.

[0038] Specifically, the extrusion block 607 is made of rubber, and its cross-section has a "︵" shape. The advantage is that by using rubber, which has good elasticity and wear resistance, and by designing its cross-section as a "︵", the extrusion block 607 can better conform to the surface of the connecting pipe during the extrusion process, increasing the contact area, thereby improving friction, enhancing the locking effect, and ensuring the stability of the fine-tuning valve body 1 during operation.

[0039] Working principle: In use, the mounting hole 403 is slidably connected to the guide post 3. Aligning the mounting hole 403 with the guide post 3 and inserting it achieves initial positioning and installation of the bracket assembly 4 and the fine-tuning valve body 1, reducing installation difficulty. Subsequently, the locking nut 404 is threadedly connected to the guide post 3, enabling quick fixation of the bracket assembly 4 and the fine-tuning valve body 1. This also facilitates quick disassembly of the bracket assembly 4 and the fine-tuning valve body 1. The inner diameter of the through hole 410 is the same as the outer diameter of the connecting post 2, facilitating both quick connection of the fixing plate 401 and the moving plate 402 to the fine-tuning valve body 1 and tight connection with the connecting post 2. To improve the stability of the connection between the connecting column 2 and the connecting valve, the adjusting screw 406 is threadedly connected to the moving plate 402, and the guide rod 408 is slidably connected to the moving plate 402. The operator can manually rotate the handwheel 405 to move the moving plate 402, thus adjusting the length of the bracket assembly 4. This meets the distance requirements between the fine-tuning valve body 1 and the connecting valve in different installation scenarios, improving the versatility of the bracket. Subsequently, a locking assembly 6 is fixedly installed inside the fixed base 5. One end of the lower pressure ring 601 and the upper pressure ring 602 inside the locking assembly 6 are rotatably connected, and the other end is connected to the rotating rod 603. The threaded connection of the locking block 604 facilitates the quick opening and closing and locking of the locking assembly 6, and facilitates quick fixation to the connecting pipe. By setting two sets of symmetrically distributed locking assemblies 6, the bracket assembly 4 can be stably connected to the connecting pipe, improving the installation stability of the fine-tuning valve body 1. Through two sets of symmetrically distributed handwheels 605, adjusting screws 606, and pressing blocks 607, the operator installs the lower pressure ring 601 and upper pressure ring 602 on the outside of the connecting pipe. When the inner diameter of the lower pressure ring 601 and upper pressure ring 602 is larger than the outer diameter of the connecting pipe, the operator can manually turn the handwheel 605 to adjust the adjusting screw 606. 06 rotates, thereby moving the extrusion block 607 towards the connecting pipe. By simultaneously extruding inwards from both sides until it is tightly fitted with the connecting pipe, the locking component 6 can be quickly fixed. This allows for the connection of pipes with different diameters, improving the versatility of the auxiliary support. By setting the extrusion block 607 to be made of rubber, which has good elasticity and wear resistance, and by setting the cross-section of the extrusion block 607 to be in the shape of a "︵", it can better fit the surface of the connecting pipe during the extrusion process, increasing the contact area, thereby improving friction, enhancing the locking effect, and ensuring the stability of the fine-tuning valve body 1 during operation.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
