Description

Technical Field

[0001] This utility model relates to the field of structural optimization and fluid control technology of industrial valves, and in particular to an adjustment component for the clearance between the butterfly plate orifice and the valve shaft. Background Technology

[0002] An adjustment assembly for the gap between a butterfly plate hole and a valve shaft is a device integrating multiple mechanical structures, including a frame, an elastic compensation ring type adjustment assembly, etc. Through the deformation of the elastic compensation ring, ratchet transmission and locking, the gap can be adjusted automatically or manually to maintain the fit between the butterfly plate hole and the valve shaft, ensuring valve sealing and stable operation.

[0003] An adjustment assembly for the clearance between a butterfly plate bore and a valve shaft mainly comprises a frame, which provides support and a mounting base for the entire assembly. Internally, it features an elastic compensation ring-type adjustment component that automatically fills the clearance using the elastic compensation ring. A long grooved guide sleeve guides the movement of the components. A locking assembly secures the positions of each component to prevent loosening. Furthermore, multiple components such as the valve, ratchet, and gears work together to achieve clearance adjustment.

[0004] Currently, traditional equipment does not employ elastic compensation ring regulating components and locking components. The gap between the butterfly plate hole and the valve shaft continuously widens due to wear, failing to automatically fill and easily leading to media leakage and a significant decrease in sealing performance. Components lack stable locking mechanisms, making them prone to loosening and displacement under vibration and pressure fluctuations, resulting in loss of fitting accuracy and increased risk of valve jamming. Frequent manual inspection and adjustment are required, increasing maintenance costs. Furthermore, long-term operation can exacerbate component wear due to excessive clearance, significantly shortening the overall service life of the equipment and making it difficult to adapt to complex operating conditions.

It aims to improve the problems in the existing technology where traditional equipment does not use an elastic compensation ring adjustment component and a locking component. As a result, the gap between the butterfly plate hole and the valve shaft continues to widen due to wear and cannot be automatically filled, which easily leads to media leakage and a significant decrease in sealing performance. Furthermore, the components lack a stable locking mechanism and are prone to loosening and displacement due to vibration and pressure fluctuations.

[0013] Reference Figure 1 , Figures 4-6The locking assembly 4 includes a connecting fastener 10, which is used to connect and fasten components within the assembly. Through the cooperation of the lever 11, connecting buckle 12, and fastener 13, quick connection and fastening are achieved, ensuring stable connection between components. The connecting fastener 10 includes a lever 11, with a connecting buckle 12 fixedly connected to one side of the lever 11. A fastener 13 is slidably connected to the outer wall of the connecting buckle 12, and the fastener 13 is fixedly connected to the outer wall of the long slot guide sleeve 3. The locking assembly 4 also includes a pull rod lock 19, which, through structures such as a fixing groove 20 and a locking block 21, achieves a locking function for components such as the long slot guide sleeve 3, preventing components from malfunctioning during operation. To prevent accidental movement and enhance the structural stability of the component, the lever lock 19 includes a fixing groove 20, which is fixedly connected to the outer wall of the long groove guide sleeve 3. The outer wall of the fixing groove 20 abuts against a locking block 21. A rotating locking block 22 is rotatably connected to one side of the locking block 21.

[0014] Working principle: First, the butterfly plate hole and valve shaft clearance adjustment assembly works in tandem through mechanical linkage and elastic compensation to achieve adaptive clearance control. When valve 5 is running, the valve shaft rotates, driving ratchet 6 to rotate. Ratchet teeth 7 mesh with reverse ratchet teeth 8, driving rotating rod 9 to drive gear 14 and rotating column 15, causing transmission rod 16 to reciprocate. Transmission rod 16 slides in sliding groove 18 through slide bar 17, pushing push block 26 to compress elastic compensation ring 27. The elastic deformation of compensation ring automatically fills the clearance between butterfly plate hole and valve shaft. If active adjustment is required, the fastening buckle 10 can be connected by lever 11, or the position of long groove guide sleeve 3 can be locked by locking block 21 and rotating locking block 22 of pull rod lock 19. The long groove structure of the guide sleeve allows for manual fine-tuning of the radial displacement of valve shaft. This dual mechanism ensures clearance stability.

[0015] Furthermore, the components achieve structural adaptation through the locking assembly 4 and the hinge 28: the lever 11 connecting the fastening buckle 10, the connecting buckle 12, and the fastening buckle 13 cooperate to quickly lock the relative position of the long groove guide sleeve 3 and the elastic compensation ring type adjusting assembly 2; the fixing groove 20 and locking block 21 of the pull rod lock 19 strengthen the locking by rotating the locking block 22 and locking the fixing block 23 to prevent the gap from changing due to vibration under operating conditions. The hinge 28 provides rotational freedom for the guide sleeve and the compensation assembly, adapting to the dynamic deformation during valve opening and closing. Ultimately, through the "active adjustment + passive compensation" of the mechanical structure, the precise fit between the butterfly plate hole and the valve shaft is continuously maintained, ensuring the valve's sealing and wear resistance performance.
