Abstract
The utility model relates to a butterfly plate with a flexible sealing device. The butterfly plate comprises a butterfly plate (1) and a sealing member (2), wherein a groove (3) is formed in the butterfly plate (1); the sealing member (2) is positioned in the groove (3); and the position at the top end of the sealing member (2) and corresponding to a valve seat is in a sawtooth shape (4). After the structure is used, the top end of the sealing member (2) is in the sawtooth shape (4), multiple layers of dentate line sealing structures are formed on the top end of the sealing member (2); and if the sealing of one layer of lines is abraded, and the other multiple layers of lines are still can be used for sealing. According to the sealing device, the butterfly plate is easily processed, and the sealing effect is guaranteed.
Description
Technical field
The utility model relates to a kind of butterfly plate that is provided with soft seal device.
Background technique
Valve is the controlling component in the fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.The title of butterfly valve derives from the butterfly plate of wings, and in the cylindrical channel of butterfly valve body, the disc butterfly plate gets final product opening/shutting valve around its butterfly plate axis or the outer axis half-twist of butterfly plate.Sealing is to prevent fluid or component or the measure of solid particle from leaking and prevent the intrusion machinery equipment inside such as introduced contaminants such as dust and moisture between adjacent junction plane, and complicated Sealing is called seal arrangement.Soft seal is comprised of metal seat valve and elastomeric seals, and elastomeric seals is a kind of composite structure, is embedded in the dentation groove of valve seat, and channel bottom is lined with elastic material.Existing elastomeric seals top is circular arc, open and close increased frequency after sealing surface can wear and tear, the sealing surface rear seal pressure that can wear and tear reduces, and does not reach the linear sealing state.
The model utility content
The purpose of this utility model is exactly to solve in the seal arrangement that has butterfly valve now to produce the problem of leaking after the wearing and tearing of Sealing top.
The technical solution adopted in the utility model is: a kind of butterfly plate that is provided with soft seal device, comprise butterfly plate and Sealing, and described butterfly plate is provided with groove, and described Sealing is positioned at groove, and the corresponding position of the top of Sealing and valve seat is zigzag fashion.
The beneficial effect that the utility model adopts is: after adopting this structure, zigzag fashion is adopted on the Sealing top, has formed like this multilayer dentation linear sealing structure on the Sealing top, even one deck linear sealing wearing and tearing still have the multilayer linear sealing, has guaranteed sealing effect.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
As shown in Figure 1, a kind of butterfly plate that is provided with soft seal device, comprise butterfly plate 1 and Sealing 2, described butterfly plate is provided with groove 3, described Sealing 2 is positioned at groove 3, and the corresponding position of the top of Sealing 2 and valve seat is zigzag fashion 4, has formed like this multilayer dentation linear sealing structure on Sealing 2 tops, if one deck linear sealing wearing and tearing still have the multilayer linear sealing.This seal arrangement easy processing, and guaranteed sealing effect.
Claims (1)
