Abstract
The utility model discloses a pushing butterfly valve, comprising a valve body, a pushing valve piece, a rotating mechanism and a power mechanism, wherein a valve opening and a pushing orbit are arranged inside the valve body; the pushing valve piece is disposed on the air inlet side of the valve opening and rotates around a rotating shaft; the rotating shaft is moved by taking the pushing orbit as the track; the power mechanism pushes the pushing valve piece to move on the pushing orbit by taking the rotating shaft as the center; the rotating mechanism is composed of a sliding block and a chute which are cooperated with each other, the sliding block is fixed on the valve body, and the chute is fixed on the pushing valve piece; and the chute at least has a first station point and a second station point which are separately corresponded to the position that the sliding block locates in the chute in the sealing and the opening working situations of the pushing butterfly valve. The pushing butterfly valve arranges the pushing valve piece on one side of the valve opening and tightly presses the valve opening by depending on pushing force, thereby largely enhancing the sealing property and advancing the working pressure range of the butterfly valve.
Description
Technical field
The utility model relates to a kind of aeroseal valve, particularly a kind of butterfly valve.
Background technique
In valve body around himself axis rotation, thereby reach the valve that opens and closes or regulate butterfly valve, it is a discoidal butterfly plate normally.The characteristics of the special-purpose butterfly valve of industry can be high temperature resistant, and suitable pressure range is also higher, is mainly used in the cigarette air channel and the gas pipe line of high temperature media.
As shown in Figure 1 and Figure 2, be the schematic representation of a kind of typical butterfly valve respectively in sealing and unlatching.Butterfly plate 11 is pressed together on the valve interior wall face with its seal ring 13 around its running shaft 12 positive and negative rotations, makes butterfly valve close (as shown in Figure 1), and perhaps butterfly plate 11 is parallel with valve body, makes fluid 14 can pass through valve port 13 (as shown in Figure 2).
As everyone knows, butterfly valve has following advantage:
1, open-close convenient is rapid, laborsaving, fluid resistance is little, can often operate.
2, simple in structure, volume is little, and is in light weight.
3, can transport mud, it is minimum to accumulate liquid in pipeline opening.
4, under the low pressure, can realize good sealing.
5, adjusting function is good.
But above-mentioned butterfly valve is difficult to accomplish tight zero-clearance because structure is limit between its running shaft and valve body, the butterfly plate; Add that the rotation drive butterfly plate by axle compresses valve port, because butterfly plate peripheral distance running shaft distance differs, makes near running shaft place pressure bigger, increase along with distance, pressure reduces gradually, causes the butterfly plate periphery to be subjected to force unbalance, so be difficult to reach sealing and do not have the leakage requirement.
In sum, the shortcoming of butterfly valve is as follows:
1, the working pressure scope is little.
2, sealing is relatively poor.
As shown in Figure 3, it is another kind of existing butterfly valve, it sets up valve port 16 on valve body, be pressed together on the described valve port 16 by diaphragm seal 15, improve the sealability of valve body, still, because the basic structure of butterfly valve does not change, the promoting effect of the sealability of 15 pairs of valve bodies of diaphragm seal is extremely limited, and effect is also not obvious.
