Description

Technical Field

[0001] This utility model relates to the field of valve plate installation and fixing technology, and in particular to a valve stem guide device that is compatible with multiple specifications. Background Technology

[0002] With the rapid development of industrial production and urban infrastructure construction, various fluid transport systems are widely used in many fields such as chemical industry, energy, and water supply and drainage. As a key control component in fluid transport systems, the performance and reliability of valves directly affect the safe and stable operation of the system. With industrial upgrading and technological innovation, the requirements for valve installation efficiency, adaptability diversity and ease of operation are constantly increasing. This drives the continuous iteration of valve-related supporting technologies and creates a demand environment for the innovative development of valve guiding devices.

[0003] Valve guide devices play a crucial role in valve systems, guiding valve movement and ensuring stable opening and closing. In practical applications, the specifications and models of valves used in different projects vary considerably, placing higher demands on the adaptability of guide devices. At the same time, convenient and efficient operation methods can significantly improve construction and maintenance efficiency and reduce labor costs. Therefore, developing valve guide devices with multi-specification adaptability and easy operation has become a key technological direction for meeting diverse market demands and improving the overall performance of valve systems.

[0004] The shortcomings of existing technology.

[0005] 1) Poor adaptability and limited application scope: Most existing valve guide devices have a fixed structure and can only be adapted to a single specification or a few specifications of valve plates. When faced with valve plates of different sizes and different installation positions, they often cannot be used directly and need to be replaced or customized. This not only increases the cost and time cost, but also limits the application of valves in diverse scenarios and makes it difficult to meet the current complex and ever-changing engineering needs.

[0006] 2) Complex operation and poor stability: The operation process of traditional valve guiding devices is cumbersome. Adjusting the position and angle of the guiding device and controlling the opening and closing of the valve requires multiple independent operation steps, resulting in low operation efficiency. Moreover, its force transmission structure is poorly designed, which can easily lead to problems with smooth force transmission, resulting in laborious operation. In addition, it lacks an effective locking structure, and the device is prone to loosening or displacement due to external forces after adjustment, which affects the normal operation of the valve, poses safety hazards, and reduces work efficiency. Utility Model Content

[0007] The purpose of this invention is to solve the problems of poor adaptability, limited application range, complex operation and poor stability in the existing technology, and to propose a valve stem guide device that adapts to multiple specifications.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a valve stem guide device adaptable to multiple specifications, comprising: a mounting plate, a first sliding plate fixedly connected to the top of the mounting plate, a set of sliding grooves opened on the top of the first sliding plate, a set of sliding components slidably arranged inside the sliding grooves, a second sliding plate fixedly connected to the top of each sliding component, a first rotating shaft fixedly connected to the top of each second sliding plate, a first crank arm rotatably connected to the outer wall of each first rotating shaft, a second rotating shaft rotatably connected to the inner wall of each first crank arm, and a second crank arm fixedly connected to the bottom of each second rotating shaft.

[0009] Preferably, a transmission assembly is fixedly connected inside the second crank arm, one end of the transmission assembly is fixedly connected to a transmission sleeve, and one end of the transmission sleeve is fixedly connected to a rotating handle.

[0010] Preferably, the rotating handle has a through-hole, and a plug-in rod is movably inserted into the through-hole. One end of the plug-in rod is fixedly connected to a locking component. A set of rotating grooves are evenly distributed around the bottom circumference of the mounting plate. A set of limiting components is fixedly connected to the bottom of the mounting plate and fixedly installed around the circumference. Each rotating groove and the limiting component are centered. Each limiting component has a through-hole, and each plug-in groove cooperates with the locking component.

[0011] Preferably, limit baffles are fixedly installed at both ends of the first sliding plate, and the limit baffles are used to limit the sliding range of the sliding component.

[0012] Preferably, each of the sliding components is fixedly mounted with a mounting component on its top, and the mounting part of each mounting component is fixedly connected to the mounting part of a fixing plate. A valve plate is fixedly connected to the outer surface of the fixing plate, and a threaded rod is fixedly connected to one end of the fixing plate. The threaded rod is movably inserted into the interior of the transmission component and the transmission sleeve.

[0013] Preferably, the outer wall of the transmission assembly is rotatably connected to the center of the first sliding plate.

[0014] Preferably, the threaded rod is used to connect the rotating components in the valve, and the rotational force drives the entire device to open and close in the water valve.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, a highly flexible adjustment system is constructed by setting a sliding component, a rotatable mounting plate, and a matching positioning and locking mechanism. Unlike traditional fixed-structure valve guide devices, which can only adapt to a single specification or a few specifications of valve plates, this device can drive the sliding component to move horizontally by rotating the rotating handle according to different sizes of valve plates and the position of the valve plate mounting part. Combined with the angle adjustment of the mounting plate, it can achieve precise adaptation and installation of valve plates of various specifications, greatly expanding the scope of application and effectively solving the problem of poor adaptability in the prior art.

[0017] 2. In this utility model, the manual operation transmission system forms a stable force transmission path by rotating the handle, transmission sleeve, and transmission components. Compared with the cumbersome operation and unsmooth force transmission of existing valve guiding devices, the operator of this device only needs to rotate the handle to easily adjust the sliding components. The operation process is simple and convenient. At the same time, the locking structure of the plug-in rod and the limit component ensures that the device remains stable during adjustment and use, avoiding loosening or displacement, improving the reliability and safety of operation, and significantly improving work efficiency.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figures 1-4 As shown, this utility model provides a valve stem guide device with multiple specifications, including: a mounting plate 1, a first sliding plate 11 fixedly connected to the top of the mounting plate 1, a set of sliding grooves 111 opened on the top of the first sliding plate 11, a set of sliding components 2 slidably arranged inside the sliding grooves 111, a second sliding plate 21 fixedly connected to the top of each sliding component 2, a first rotating shaft 23 fixedly connected to the top of each second sliding plate 21, a first crank arm 24 rotatably connected to the outer wall of each first rotating shaft 23, a second rotating shaft 25 rotatably connected to the inner wall of each first crank arm 24, and a second crank arm 251 fixedly connected to the bottom of each second rotating shaft 25.

[0026] The overall effect of Embodiment 1 is that, through the combination of components such as mounting plate 1, first sliding plate 11, sliding groove 111, sliding assembly 2, second sliding plate 21, first rotating shaft 23, first crank arm 24, second rotating shaft 25 and second crank arm 251, a basic structural framework with flexible adjustment capability is constructed. The sliding function of sliding assembly 2 in sliding groove 111 can realize horizontal displacement adjustment; it lays a structural foundation for adapting to valve plates of different sizes, so that the device can be adaptively adjusted according to the size of the valve plate and the position of the valve plate mounting part.

[0027] Example 2: Figures 1-4 As shown, a transmission assembly 26 is fixedly connected inside the second crank arm 251. One end of the transmission assembly 26 is fixedly connected to a transmission sleeve 27, and one end of the transmission sleeve 27 is fixedly connected to a rotating handle 28.

[0028] The overall effect of Embodiment 2 is that the transmission component 26, transmission sleeve 27 and rotating handle 28 inside the second crank arm 251 form a manual operation transmission system. The rotating handle 28 facilitates the operator to apply force, and the force is transmitted to the transmission component 26 through the transmission sleeve 27, realizing the transmission and conversion of force. This transmission system not only makes it convenient for users to operate the valve stem guide device, but also provides stable power transmission for adjustment operation when adapting to valve plates of different sizes, enhancing the flexibility and practicality of the device.

[0029] Example 3: As Figures 1-4 As shown, the inside of the rotating handle 28 is provided with an insertion hole 3, and an insertion rod 31 is movably inserted into the insertion hole 3. One end of the insertion rod 31 is fixedly connected to a locking component 32. A set of rotating grooves 33 are evenly provided around the bottom circumference of the mounting plate 1. A set of limiting components 34 are fixedly installed around the bottom of the mounting plate 1. Each rotating groove 33 and the limiting component 34 are centered. Each limiting component 34 is provided with an insertion groove 341, and each insertion groove 341 cooperates with the locking component 32.

[0030] The overall effect of embodiment 3 is that the insertion hole 3, insertion rod 31, and locking assembly 32 inside the rotating handle 28, together with the rotating groove 33, limiting assembly 34, and insertion groove 341 at the bottom of the mounting plate 1, constitute a precise positioning and locking mechanism. When it is necessary to adjust the position or angle of the device to adapt to different sized valve plates, the insertion rod 31 can be pulled out, so that the locking assembly 32 disengages from the insertion groove 341 for flexible rotation. After the adjustment is completed, the insertion rod 31 is inserted, and the locking assembly 32 engages with the insertion groove 341 to lock, ensuring that the device remains stable when adapting to different valve plates, preventing displacement due to external forces, and ensuring the reliability of the device and the accuracy of the adaptation.

[0031] Example 4: Figures 1-4 As shown, limit baffles 12 are fixedly installed at both ends of the first sliding plate 11. The limit baffles 12 are used to limit the sliding range of the sliding component 2.

[0032] The effect achieved by the entire embodiment 4 is that the limiting baffles 12 at both ends of the first sliding plate 11 restrict the sliding range of the sliding component 2, preventing the sliding component 2 from disengaging from the sliding groove 111 during the sliding process, thus ensuring the safety and stability of the sliding structure.

[0033] Example 5: Figures 1-4 As shown, each sliding component 2 is fixedly mounted on top of an installation component 5, and the installation part of each installation component 5 is fixedly connected to the installation part of a fixing plate 41. A valve plate 42 is fixedly connected to the outer surface of the fixing plate 41, and a threaded rod 4 is fixedly connected to one end of the fixing plate 41. The threaded rod 4 is movably inserted into the inside of the transmission component 26 and the transmission sleeve 27.

[0034] The overall effect of embodiment 5 is that the connection design of the mounting component 5, fixing plate 41, valve plate 42 and threaded rod 4 on the top of the moving component 2 realizes the effective combination of the guide device and valve plates of different sizes. Through the mounting component 5 and fixing plate 41, valve plates 42 of different sizes can be stably installed on the device. The threaded rod 4 is movably inserted into the transmission component 26 and transmission sleeve 27, so that the guide device can provide guidance and support for the installation and operation of the valve plate, ensuring the device's adaptability and guiding function for valve plates of different specifications, and meeting diverse installation and use needs.

[0035] Example 6: As Figures 1-4 As shown, the outer wall of the transmission assembly 26 is rotatably connected to the center of the first sliding plate 11.

[0036] The overall effect of embodiment 6 is that this connection method makes the transmission component 26 more smoothly transmit force and motion, reduces friction and resistance caused by unreasonable connection, improves transmission efficiency, and ensures that the stable and efficient transmission can ensure that the components of the device work together in the process of adapting to valve plates of different sizes, providing power support for the installation and adjustment of valve plates.

[0037] Example 7: Figures 1-4 As shown, the threaded rod 4 is used for the rotating component in the threaded connection valve, and the rotational force drives the entire device to open and close in the water valve.

[0038] The effect achieved by the entire embodiment 7 is that the threaded rod 4, as a key component connecting the guide device and the valve plate, is designed to ensure that after valve plates of different sizes are installed, the force applied by the operator through the rotating component in the water valve can be accurately applied to the valve plate to adjust the state of the valve plate.

[0039] Working principle: When it is necessary to adapt to valve plates of different sizes, the operator rotates the rotating handle 28. The rotating handle 28 transmits the rotational power to the transmission component 26 through the transmission sleeve 27. The transmission component 26 then applies force to the sliding component 2, driving the sliding component 2 to slide within the sliding groove 111 of the first sliding plate 11. This achieves horizontal displacement adjustment of the device, thus initially adapting to the lateral installation requirements of the valve plate. During this process, the limiting baffles 12 at both ends of the first sliding plate 11 function to limit the sliding range of the sliding component 2, preventing it from disengaging from the sliding groove 111, and ensuring the safety and accuracy of the sliding adjustment. The operator then pulls out the insertion rod 31 from the insertion hole 3 of the rotating handle 28, causing the locking component 32 to disengage from the limiting component 3. The insertion slot 341 of 4 allows the mounting plate 1 to rotate around the rotating slot 33 as the axis. After adjusting to a suitable angle, the insertion rod 31 is reinserted, and the locking component 32 engages with the insertion slot 341 to lock it in place, ensuring the device remains stable when adapting to different valve plates and preventing displacement due to external forces. After the position adjustment is completed, the mounting component 5 on the top of the sliding component 2 fixes the fixing plate 41 to the valve plate 42, achieving a stable connection between the guide device and valve plates of different sizes. Subsequently, when the valve plate needs to be opened or closed, the threaded rod 4 is threadedly connected to the rotating component in the valve, ultimately accurately transmitting the rotational force to the valve plate, achieving precise adjustment of the valve plate's state, and completing the entire process from adaptation and installation to operation control for valve plates of different specifications.

[0040] The wiring diagrams of the threaded rod 4 and valve plate 42 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring arrangement of the threaded rod 4 and valve plate 42 will not be explained in detail.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
