Abstract
The invention discloses a high-performance sealing butterfly valve of a core shift structure. The high-performance sealing butterfly valve comprises a valve body, a butterfly plate, a valve shaft, a valve seat, an air cylinder and a positioner. The air cylinder is arranged over the valve body; the positioner is arranged between the valve body and the air cylinder and is used for adjusting the opening proportion of the butterfly plate; the valve shaft penetrates through the butterfly plate to be fixed to the valve seat. The high-performance sealing butterfly valve of the core shift structure has the beneficial effects of being simple in structure, small in size, large in output force and long in service life.
Description
Technical field
The present invention relates to a kind of invention, particularly relate to a kind of high-performance sealed butterfly valve of core shift structure.
Background technique
Seal butterfly valve is used for realizing pipe-line system cuts off and the parts of flow control as a kind of, obtain applying very widely in many fields such as oil, chemical industry, metallurgy, water power, but rubbing between seal butterfly valve its butterfly plate sealing surface and sealing surface of seat of commonly using at present is larger, therefore the working life that the keying moment of butterfly valve just height, and frictional force result in greatly butterfly valve is lower.
Summary of the invention
The object of the invention is to the defect overcoming prior art, the high-performance sealed butterfly valve of the simple long service life of a kind of structure is provided.
For achieving the above object, the present invention proposes following technological scheme: a kind of high-performance sealed butterfly valve of core shift structure, comprise valve body, butterfly plate, valve shaft, valve seat, cylinder and positioning work piece, described cylinder is located at above described valve body, and described positioning work piece is located between described valve body and shown cylinder, the ratio of opening for regulating butterfly plate, described valve shaft is fixed on described valve seat through butterfly plate.
Described valve seat is teflon, and synthetic rubber and phenolic resin are composited.
Described valve shaft is special valve shaft.
Compared with prior art, it is simple that the high-performance sealed butterfly valve of disclosed a kind of core shift structure has structure, and volume is little, High power output and life-span long feature.
Accompanying drawing explanation
Fig. 1 is the high-performance sealed butterfly valve structure schematic diagram of disclosed core shift structure.
Embodiment
Below in conjunction with accompanying drawing of the present invention, clear, complete description is carried out to the technological scheme of the embodiment of the present invention.
As shown in Figure 1, the high-performance sealed butterfly valve of disclosed a kind of core shift structure, comprise valve body 1, butterfly plate 2, valve shaft 3, valve seat 4, cylinder 5 and positioning work piece 6, described cylinder 5 is located at above described valve body 1, and described positioning work piece 6 is located between described valve body 1 and shown cylinder 5, the ratio of opening for regulating butterfly plate, described valve shaft 3 is fixed on described valve seat 4 through butterfly plate 2.
Particularly, described valve shaft 3 is special valve shaft, make the sealing surface of described butterfly plate 2 the moment of closing just and the sealing surface of described valve seat 4 contact, reduce frictional force when sealing surface contacts, thus reduce the keying moment of described butterfly valve 2, improve the working life of described butterfly valve 2, make sealing more reliable.
Described valve seat 4 is teflon, and synthetic rubber and phenolic resin are composited.
Technology contents of the present invention and technical characteristics have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from spirit of the present invention based on teaching of the present invention and announcement; therefore; scope should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present invention and modification should be comprised, and contained by present patent application claim.
Claims (3)
