Description

Technical Field

[0001] This utility model belongs to the technical field of valve braking devices, and specifically relates to a valve electric booster. Background Technology

[0002] The medium inside the pipelines at a solar thermal site is in a high-temperature and high-pressure environment. Manually opening and closing valves may cause leakage or outward spray of the medium inside the pipeline, thereby endangering the personal safety of personnel on site. Therefore, it is not suitable to manually open and close the pipeline valves at a solar thermal site.

[0003] For pipes and valves that have already been installed and put into use, replacing the valves in a centralized manner would require a lot of manpower, material resources and financial resources. Utility Model Content

[0004] This utility model provides a valve electric booster to solve the problem of high risk of valve opening in solar thermal field pipelines.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A valve electric booster, comprising: The limiting device includes a fixed plate and two limiting rods. The limiting rods are installed on the fixed plate. When the limiting device is installed on a pipeline, the two limiting rods are located on both sides of the pipeline and clamp the pipeline. A drive assembly, mounted on the fixed plate, is used to provide power for rotating the valve; A locking component is installed at the output end of the drive component. The drive component drives the locking component to rotate, and the locking component locks onto the valve and pushes the valve to rotate. Furthermore, the drive assembly includes a speed-regulating motor detachably mounted on the fixed disk, the output end of the speed-regulating motor is mounted on the drive disk, and the locking assembly is mounted on the side of the drive disk away from the speed-regulating motor.

[0006] Furthermore, the locking assembly includes multiple mounting blocks, each mounting block being detachably equipped with a latching element, and the valve stem is clamped between the latching element and the mounting block.

[0009] Furthermore, the slot includes an opening and a reduced diameter portion that are interconnected, the reduced diameter portion being disposed above the opening, and a rubber pad being fixed inside the slot.

[0010] Furthermore, the fixed plate includes a plate body and a mounting section fixed on the plate body, and the limiting rod is threadedly connected to the mounting section.

[0011] Furthermore, the speed-regulating motor is provided with an installation sleeve, the inner side of the fixing plate is provided with multiple installation positions, and the outer wall of the installation sleeve is provided with multiple installation keys at intervals. The multiple installation keys are inserted and fixed into the installation positions one by one.

[0012] Furthermore, the drive disk includes a rotating part and a protective part. The protective part is disposed near the side of the speed-regulating motor, and the diameter of the protective part is larger than the diameter of the rotating part. At the same time, the area of ​​the protective part is larger than the cross-sectional area of ​​the speed-regulating motor.

[0013] Furthermore, a rubber friction layer is provided on the outside of the limiting rod.

[0014] The present invention can achieve the following beneficial effects: 1. This application uses a limiting device to install the entire device on the pipeline.

Detailed Implementation

[0019] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0020] Example 1 like Figures 1 to 3 As shown, a valve electric booster includes a limiting device 1, a driving component 2 mounted on the limiting device 1, and a locking component 3 mounted on the end of the driving component 2. The limiting device 1 is used to install the device onto the pipeline 100 and provides a fixed mounting point for the driving component 2. The driving component 2 drives the locking component 3 to rotate, and the locking component 3 locks onto the valve 200. When the locking component 3 rotates, it can push the valve 200 to rotate.

[0021] The limiting device 1 includes a fixed plate 11 and limiting rods 12. The limiting rods 12 are detachably mounted on the fixed plate 11, and two limiting rods 12 are provided. When the electric booster of this application is installed on the pipe 100, the two limiting rods 12 are located on both sides of the pipe 100 and clamp the pipe 100. With this arrangement, when the drive assembly 2 drives the locking assembly 3 to rotate, the limiting rods 12 can lock the limiting device 1 in place, preventing the limiting device 1 from rotating. The limiting device 1 has a simple structure, is easy to install, and does not need to be installed or disassembled with the pipe 100, reducing the impact on the structure of the pipe 100.

[0022] Specifically, the fixed plate 11 includes a plate body 111 and an installation section 112 integrally formed with the plate body 111. The number of installation sections 112 is the same as the number of limiting rods 12. Threaded holes are provided in the installation sections 112, and the limiting rods 12 are threaded onto the installation sections 112. This design allows the limiting rods 12 to be detachably connected to the fixed plate 11, facilitating storage and ensuring that only the size of the fixed plate 11 needs to be changed for pipes 100 of different diameters, while the limiting rods 12 are universally compatible.

[0023] It should be noted that the limiting rod 12 is wrapped with a rubber friction layer, which increases the friction between the limiting rod 12 and the pipe 100, making it difficult for the limiting rod 12 and the pipe 100 to slide relative to each other, and making the installation of the limiting device 1 more stable.

[0024] The drive assembly 2 includes a speed-regulating motor 21 that is detachably mounted on the fixed disk 11. The speed-regulating motor 21 includes a motor and a reducer. The motor provides driving force, and the reducer adjusts the rotation speed of the rotary valve 200. A drive disk 22 is installed at the output end of the reducer, and the locking assembly 3 is installed on the side of the drive disk 22 away from the reducer.

[0025] Furthermore, the speed-regulating motor 21 is fitted with a mounting sleeve 23, and the outer wall of the mounting sleeve 23 is circumferentially spaced with multiple mounting keys 231. Correspondingly, the inner side of the disc body 111 is circumferentially provided with multiple mounting positions 113. When the speed-regulating motor 21 is installed on the limiting device 1, the multiple mounting keys 231 are inserted and fixed into the mounting positions 113 one by one, and the mounting keys 231 and the mounting positions 113 are connected by bolts and nuts. The speed-regulating motor 21 and the limiting device 1 are detachably connected, which facilitates the maintenance, replacement and storage of the speed-regulating motor 21 and the limiting device 1.

[0026] The positioning assembly 3 includes multiple mounting blocks 31, which are spaced apart circumferentially along the drive disc 22 and positioned near the outer edge of the drive disc 22. Each mounting block 31 can be detachably mounted with a latching element 32, which includes a triangular groove 321 on its end face. When the latching element 32 is mounted on the mounting block 31, the valve stem is confined within the triangular groove 321. Because it is a triangular groove, it can accommodate valve stems of different diameters, allowing the valve 200 to rotate adaptively when the drive disc 22 rotates. Simultaneously, the valve stem being confined within the triangular groove 321 allows the positioning assembly 3 to support the upper electric booster, thus enabling the entire device to be stably installed by relying on both the limiting rod 12 and the positioning assembly 3 for support and limitation.

[0027] The fastener 32 has threaded mounting holes 322 near both the top and bottom ends, and the mounting block 31 has corresponding threaded fixing holes 311. When the fastener 32 is installed onto the mounting block 31, only bolts are needed to achieve a stable and tight connection between the fastener 32 and the mounting block 31.

[0028] Furthermore, the drive disc 22 includes a rotating part 221 and a protective part 222. The protective part 222 is located near the speed-regulating motor 21, and its diameter is larger than that of the rotating part 221. Simultaneously, the area of ​​the protective part 222 is larger than the cross-sectional area of ​​the speed-regulating motor 21. This allows the protective part 222 to protect the drive assembly 2, preventing damage to the drive assembly 2 from leakage or splashing of the medium within the pipeline 100 when the gate is opened. Specifically, the protective part 222 can be a plastic sheet or other corrosion-resistant, hard, and inexpensive material. It should be noted that... Figure 1 The protective section 222 was not shown in the text.

[0029] Example 2 Reference Figure 4 The difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the locking component 3 includes multiple mounting ridges 33. These mounting ridges 33 are spaced apart on the drive disk 22 and circumferentially surround it, with each mounting ridge 33 extending radially along the drive disk 22. Each mounting ridge 33 has a locking groove 331 on its sidewall. The locking groove 331 is located on the same side of the mounting ridges 33, extends radially along the drive disk 22, and penetrates both ends of the mounting ridge 33. The locking groove 331 includes an interconnected opening and a reduced diameter portion. The opening penetrates the sidewall of the mounting ridge 33, and the reduced diameter portion is located within the mounting ridge 33 and above the opening. The locking groove 331 allows the valve stem to be engaged and supports the entire electric booster.

[0030] Specifically, when the valve 200 is rotated, the valve stem is engaged in the locking groove 331. The electric booster presses down on the valve stem under gravity, causing it to be accommodated within the reduced-diameter section. Because the reduced-diameter section is triangular, it can adapt to valve stems of different diameters to maintain the valve stem's fixed position. Furthermore, a rubber pad is fixed to the side wall of the locking groove 331 to increase the friction between the valve stem and the side wall of the locking groove 331, making it less likely for the valve stem to slide relative to the mounting edge 33.

[0031] It should be noted that the contact area between the positioning component 3 and the valve stem is small in Embodiment 1 of this application, making it suitable for valves 200 with complex structures and patterns. Embodiment 2 of this application is simple and convenient to install, has uniform force distribution and strong pushing force. For valves 200 that can utilize the structure of Embodiment 2 of this application, the positioning component 3 structure of Embodiment 2 is preferred.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
