Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an electric valve fixing device. Background Technology
[0002] Electric valves are automated valves driven by electricity, used to control the on / off state and flow rate of fluids. They are widely used in HVAC, industrial and other fields. During operation, they are prone to displacement due to medium impact, self-vibration or external interference, which can lead to loose connections, leakage or even equipment damage. Therefore, they need to be securely installed by fixing devices to ensure stable and safe operation and ensure the reliable operation of the entire fluid.
[0003] An electric valve fixing device typically includes a support base for supporting the electric valve body, on which fastening components such as bolts or clips are provided to connect and fix the electric valve to the base. The device is also equipped with an adjustment mechanism to fine-tune the installation position of the electric valve, and a buffer to reduce the impact of vibration. There is also a connection part for connecting to pipelines or equipment, and some also have positioning pins to ensure accurate installation. All the mechanisms work together to achieve stable fixing of the electric valve.
[0004] In existing technologies, some electric valve fixing devices rely on bolt fastening. However, due to the continuous vibration of the electric valve during operation, the bolts gradually loosen. This vibration continuously weakens the bolt preload, and the preload drops significantly over time, making it difficult to stably lock the electric valve. When the preload is insufficient, gaps easily form between the fixing device, the electric valve, and the mounting foundation, leading to relative displacement. This not only affects the sealing performance of the electric valve and the pipeline but also exacerbates equipment wear and reduces the operational reliability of the entire device. Therefore, an electric valve fixing device is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figure 1 , Figure 2 and Figure 5 The present invention provides an embodiment of an electric valve fixing device, comprising a motor 1, a control tube 2 fixedly connected to the bottom end of the motor 1, the motor 1 serving as a power source, the bottom end of which is fixed to the top end of the control tube 2 by welding, the power generated by the motor 1 during operation can be directly transmitted to the control tube 2 to realize the operation of closing and opening the valve, two sliding rings 3 are slidably connected to the outer wall of the control tube 2, the outer wall of the control tube 2 is smoothed, the inner wall of the two sliding rings 3 is clearance-fitted with the outer wall of the control tube 2, and can slide along the axial direction of the control tube 2 to realize the position adjustment of the sliding rings 3;
[0035] A fixing mechanism 4 is installed on the outer wall of the sliding ring 3. The fixing mechanism 4 moves synchronously with the sliding ring 3 to achieve clamping and loosening operations. When the two sliding rings 3 are close to each other, the electric valve can be disassembled. When the two sliding rings 3 are far apart, the electric valve can be installed. A cleaning mechanism 6 is installed on the outer wall of the sliding ring 3. The cleaning mechanism 6 is also fixed on the outer wall of the sliding ring 3 and moves synchronously with the sliding ring 3. During the sliding process, it cleans the water pipe 5. The fixing mechanism 4 and the cleaning mechanism 6 are installed on both the front and rear sides of the control pipe 2. Each fixing mechanism 4 contains three clamping components 46.
[0036] The fixing mechanism 4 includes a pull ring 41, which is a ring-shaped mechanism and is the operating component of the fixing mechanism 4. It allows the operator to pull the ring 41 to clamp and loosen the control pipe 2 and the water pipe 5. Limiting rings 42 are fixedly connected to the far sides of the two sliding rings 3. The limiting rings 42 are fixed to the sliding rings 3 by welding. The limiting rings 42 are the core mechanism for the operation of the fixing mechanism 4. The limiting rings 42 can move together with the sliding rings 3. When the two sliding rings 3 are close to each other, the limiting rings 42 lose their compression on the sliding block 45. At this time, the operation of disassembling the electric valve is performed. When the two sliding rings 3 are far apart, the limiting rings 42 re-compress the sliding block 45. At this time, the operation of installing the electric valve is performed.
[0037] Multiple support blocks 43 are fixedly connected to the opposite side of the control pipe 2. The support blocks 43 provide a stable mounting point for the damper 44 and support the reset operation of the sliding block 45. The damper 44 is fixedly connected to the outer wall of the support block 43. One end of the damper 44 is fixed to the outer wall of the support block 43 by welding. It can absorb the energy generated by the vibration of the electric valve and reduce the vibration transmission. The sliding block 45 is fixedly connected to the outer wall of the damper 44. The other end of the sliding block 45 is connected to the damper 44 by welding. When the sliding block 45 is squeezed, the damper 44 performs a contraction operation. When the spring 7 supports the sliding block 45 to complete the reset, the damper 44 performs a stretching operation. Clamping components 46 are provided on the opposite side of the multiple sliding blocks 45. The clamping components 46 adjust the clamping position as the sliding block 45 moves to achieve the fixation between the control pipe 2 and the water pipe 5.
[0038] Reference Figure 2 The clamping assembly 46 includes hooks 461, which are metal claw-shaped mechanisms with a certain degree of elasticity. The adjacent sides of multiple hooks 461 are fixedly connected to the distant sides of multiple sliding blocks 45. The hooks 461 are fixed by welding and can move together with the sliding blocks 45. Their claws face the center of the control tube 2. The outer walls of multiple hooks 461 are detachably connected to fastening rings 462, which are ring-shaped mechanisms. The linkage between the fastening rings 462 and the hooks 461 achieves fastening. When the hooks 461 are tightened, multiple hooks 461 can retract inward toward the center of the control tube 2 to clamp the fastening ring 462. When the hooks 461 are relaxed, multiple hooks 461 can slide outward toward the center of the control tube 2 to relax the fastening ring 462.
[0039] Reference Figure 2 and Figure 5 The cleaning mechanism 6 includes a cleaning ring 61, which is a ring-shaped support structure and serves as the mounting carrier for the scraping ring 62. The inner wall of the cleaning ring 61 is fixedly connected to the outer wall of the sliding ring 3. The inner wall of the cleaning ring 61 is fixedly welded to the outer wall of the sliding ring 3 and moves synchronously with the sliding ring 3. The inner wall of the cleaning ring 61 is fixedly connected to the scraping ring 62, which is made of wear-resistant elastic material and is used to scrape off impurities from the surface of the 5. A spring 7 is sleeved on the outside of the damper 44 and works in conjunction with the damper 44. The spring 7 provides elastic restoring force to the sliding block 45.
[0040] Multiple sliding blocks 45 are slidably connected on their adjacent sides to the opposite sides of the control tube 2. For the front fixing mechanism 4, the rear side of the sliding block 45 slides on the front side of the control tube 2 to ensure that the sliding block 45 slides smoothly. One end of the spring 7 is fixedly connected to the outer wall of the sliding block 45. The other end of the spring 7 is fixedly welded to the outer wall of the sliding block 45 and extends and retracts as the sliding block 45 moves. The other end of the spring 7 is fixedly connected to the outer wall of the support block 43. The support block 43 provides support for the spring 7 to release its elastic force stably. The opposite sides of the two fastening rings 462 are fixedly connected to the support ring 463. For the front fixing mechanism 4, the front side of the fastening ring 462 is fixed with the support ring 463. The support ring 463 is used to connect the water pipe 5 and the fastening ring 462.
[0041] Water pipes 5 are fixedly connected to the opposite sides of the support ring 463. The water pipes 5 are connected to the support ring 463 by welding. The water pipes 5 are used to transport fluid media. The inner walls of the two limiting rings 42 are slidably connected to the outer wall of the control pipe 2. The limiting rings 42 and the control pipe 2 slide together and slide together with the sliding ring 3. The inner wall of the scraping ring 62 is in contact with the outer wall of the water pipe 5. When the scraping ring 62 moves with the cleaning ring 61, it can scrape off the dust and stains on the outer wall of the water pipe 5. The inner wall of the water pipe 5 is slidably connected to the outer wall of the limiting ring 42. The water pipe 5 and the limiting ring 42 are in clearance fit and can slide relative to each other to enhance structural stability. The adjacent sides of the two water pipes 5 can be disassembled to the opposite sides of the two sliding rings 3. Disassembly means that when the water pipe 5 and the sliding ring 3 are in contact with each other, the electric valve installation operation is completed. When the water pipe 5 and the sliding ring 3 are far apart, the electric valve disassembly operation is completed.
[0042] Working principle: The operator pulls outward the pull ring 41, which drives the sliding ring 3 to slide outward along the outer wall of the control tube 2. At this time, the two sliding rings 3 move closer to each other, and the limiting ring 42 on the far side of the sliding rings 3 moves and slides out. The limiting ring 42 loses its compression on the sliding block 45, and the spring 7 begins to release its elastic force. The spring 7 supports the sliding block 45 to slide away from the center of the control tube 2. The sliding block 45 drives the hook 461 to move away from the center of the control tube 2 at the same time. At this time, the hook 461 loses its constraint on the fastening ring 462, and the electric valve can be disassembled. When installing the electric valve, the operator pushes inward. Pulling ring 41 causes sliding ring 3 to slide inward along the outer wall of control pipe 2. The two sliding rings 3 move away from each other, and the limiting ring 42 on the far side of the sliding ring 3 moves accordingly and re-presses the sliding block 45. Spring 7 is compressed and stores elastic force. Under the action of compression, the sliding block 45 slides towards the center of control pipe 2, and at the same time drives the hook 461 to move synchronously. At this time, the hook 461 generates a constraint force on the fastening ring 462. When the fastening ring 462 is between the hook 461, the hook 461 fastens the fastening ring 462, so that the electric valve fits tightly against the water pipe, and the installation and fixing of the electric valve is completed.
[0043] During the process of the pulling ring 41 driving the sliding ring 3 to be pulled outward or pushed inward, the cleaning ring 61 fixed to the outer wall of the sliding ring 3 will move synchronously. The cleaning ring 61 is fixed to the sliding ring 3 by welding. The scraping ring 62 is made of wear-resistant elastic material. Because it is in close contact with the outer wall of the water pipe 5, it will slide on the outer wall of the water pipe 5 as the cleaning ring 61 moves. When the sliding ring 3 moves outward, the two sliding rings 3 move closer to each other, and the scraping ring 62 slides along the outer wall of the water pipe 5 towards the center of the device to scrape away the dust and stains in that area. When the sliding ring 3 moves inward, the two sliding rings 3 move away from each other, and the scraping ring 62 slides away from the center of the device to further clean other areas of the outer wall of the water pipe 5, so as to achieve a comprehensive cleaning of the outer wall of the water pipe 5, avoid the accumulation of impurities and affect the operation of the equipment, and form a coordinated linkage with the action of the fixing mechanism 4.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
