Abstract
The utility model provides a butterfly plate structure, the valve shaft mounting hole of butterfly plate is the rectangle trough - shaped structure of open -type, and its opening part seals through the detachable apron, the valve shaft is packed into setting up the adjustment through valve shaft bottom behind the valve shaft mounting hole and filling up the center height who adjusts the valve shaft, the valve shaft surface has two planar structure that parallel, planar structure with the lateral wall of valve shaft mounting hole cooperatees. The beneficial effects of the utility model are that: butterfly plate structure is simple, and milling process is efficient, and the precision easily guarantees, and with the convenient assembling of valve shaft, the valve shaft position accuracy is easily controlled, compares with the structure that the taper pin is connected, does not have the risk of leakage, seals effectually.
Description
Technical field
The utility model relates to a kind of valve part, particularly relates to butterfly plate structure.
Background technique
Current existing butterfly plate be connected by key, spline or taper pin between valve shaft, the deficiency of these two kinds of structures is: with key or spline joint, in order to ensure the positional accuracy of valve shaft, butterfly plate need be placed in valve body during processing valve shaft mounting hole and join boring, work efficiency is low, and circumferential required precision is high; When connecting with taper pin, taper pin runs through butterfly plate, and its junction easily produces the leakage of medium.
Model utility content
In order to overcome the above-mentioned shortcoming of existing butterfly plate, the utility model provides a kind of work efficiency high, easy for installation and the butterfly plate structure of No leakage risk.
The utility model solves the technological scheme that its technical problem adopts, a kind of butterfly plate structure, and the valve shaft mounting hole of butterfly plate is the rectangle channel-shaped structure of open type, and its opening is closed by dismountable cover plate; Adjust the center height of valve shaft after valve shaft loads described valve shaft mounting hole by setting up spacer bottom valve shaft, valve shaft outer surface has two plane structures paralleled, and plane structure matches with the sidewall of described valve shaft mounting hole.
The beneficial effects of the utility model are: butterfly plate structure is simple, and Milling Process efficiency is high, and precision easily ensures, and easy to assembly with valve shaft, valve shaft position precision is easy to control, compared with the structure connected with taper pin, and No leakage risk, good sealing effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment.
In figure: 1. cover plate; 2. valve shaft; 3. plane structure; 4. valve shaft mounting hole; 5. spacer; 6. butterfly plate.
Embodiment
As shown in Figure 1, a kind of butterfly plate structure, the valve shaft mounting hole 4 of butterfly plate 6 is the rectangle channel-shaped structure of open type, and its opening is closed by dismountable cover plate 1; By setting up the center height that spacer 5 adjusts valve shaft 2 bottom valve shaft 2 after valve shaft 2 loads described valve shaft mounting hole 4, valve shaft 2 outer surface has two plane structures paralleled 3, and plane structure 3 matches with the sidewall of described valve shaft mounting hole 4.
Claims (1)
1. a butterfly plate structure, is characterized in that: the valve shaft mounting hole of described butterfly plate is the rectangle channel-shaped structure of open type, and its opening is closed by dismountable cover plate; Adjust the center height of valve shaft after valve shaft loads described valve shaft mounting hole by setting up spacer bottom valve shaft, described valve shaft outer surface has two plane structures paralleled, and described plane structure matches with the sidewall of described valve shaft mounting hole.
