Abstract
The utility model discloses a butterfly plate area three -section circular arc seals one end flange telescopic butterfly valve, it has had the butterfly valve to adopt the sealed butterfly plate of the full conical surface to solve, opens and close the difficulty, and the life weak point is maintained inconveniently and the inconvenient problem of installation change. Sealing washer (10) are fixed in the seal groove of valve body (1) by clamping ring (11), and clamping ring and valve body are linked firmly through pin (6) with valve shaft (2) by screw connection, butterfly plate (9), the sealed face of butterfly plate (9) by first, two, three arc surfaces are tangent in proper order constitutes, the second arc surface forms sealed pair with the fourth arc surface rd of sealing washer (10).
Description
technical field:
The utility model is relevant with butterfly valve, especially relevant with cities and towns water drainage-supply system soft sealing butterfly valve.
background technique:
Current water drainage-supply system butterfly valve, the rubber seal be embedded on valve body or butterfly plate by compression is produced magnitude of interference and realizes sealing, adopts the butterfly plate of full conical surface seal opening and closing in process, because seal ring magnitude of interference is large, cause and open and close difficulty, seal ring is fragile to come off, and working life is short.
Two ends are the butterfly valve of fastening flange, need to support the use with expansion bend during installation, are convenient to install and change, but many expansion bends, improve installation cost and maintain and replace expense.
model utility content:
The purpose of this utility model is to provide one, and to open and close moment little, and good seal performance, long service life, butterfly plate convenient for installation and maintenance sealing wear three sections of telescopic butterfly valves of circular arcs sealing end flange.
The utility model is achieved in that
Seal ring 10 is fixed in the seal groove of valve body 1 by trim ring 11, trim ring is connected by screw with valve body, butterfly plate 9 and valve shaft 2 are connected by pin 6, and the sealing surface of butterfly plate 9 is formed by first, second and third arc surface is tangent successively, and the 4th arc surface Rd of the second arc surface and seal ring 10 forms sealing pair.
The telescopic pipe 3 that one end of valve body has flange to be connected with straight-run of pipe and forms stretches in valve body 1, valve body 1 end that is connected with telescopic pipe 3 has a groove, groove is built with compressible O-ring seals 7, trim ring 8 is housed outward, by regulating attachment screw to regulate O shape circle decrement, prevent the medium in pipeline from leaking outside.Telescopic pipe 3 is connected spacing with valve body 1 limit pull rod 5 and nut 4, telescopic pipe 3 can limit scope in free-extension.
The utility model has the following advantages:
One, the sealing surface of butterfly plate is processed with three sections of arc surfaces, when butterfly valve opens and closes, butterfly plate rotates along valve shaft 1, in the process that butterfly plate 4 opens and closes, first and third arc surface is approaching face, and decrement is less, moment is less, second arc surface is the cambered surface sealed with rubber seal 10, and compression magnitude of interference remains unchanged, and valve opening and closing is light and flexible, good seal performance more.
Two, due to butterfly plate sealing cambered surface 2 and seal ring magnitude of interference evenly constant, first and third arc surface is approaching face, and decrement is less, butterfly plate is worn and torn in opening-closing process less, extends valve working life.
Three, telescopic pipe is connected spacing with valve body limit pull rod and nut, telescopic pipe can limit scope in free-extension, be convenient to the installation and maintenance of valve.
Four, applied range, the three sections of circular arc sealings of butterfly plate band, the telescopic butterfly valve series product of end flange, can meet the use needs of the different latus rectum of cities and towns water drainage-supply system and different pressures.
accompanying drawing illustrates:
Fig. 1 is Total Product figure of the present utility model.
Fig. 2 is the amplification assumption diagram of butterfly plate three sections of circular arc sealings.
embodiment:
Seal ring 10 is fixed in the seal groove of valve body 1 by trim ring 11, trim ring is connected by screw with valve body, butterfly plate 9 and valve shaft 2 are connected by pin 6, and the sealing surface of butterfly plate 9 is formed by first, second and third arc surface is tangent successively, and the 4th arc surface Rd of the second arc surface and seal ring 10 forms sealing pair.
The telescopic pipe 3 that one end of valve body has flange to be connected with straight-run of pipe and forms stretches in valve body 1, valve body 1 end that is connected with telescopic pipe 3 has a groove, groove is built with compressible O-ring seals 7, trim ring 8 is housed outward, by regulating attachment screw to regulate O shape circle decrement, prevent the medium in pipeline from leaking outside.Telescopic pipe 3 is connected spacing with valve body 1 limit pull rod 5 and nut 4, telescopic pipe 3 can limit scope in free-extension.
Valve shaft 2 drives butterfly plate 9 to rotate, and the sealing surface of butterfly plate 9 has three sections of arc surface arc 1-Ra, arc 2-Rb, arc 3-Rc, and arc surface arc 2 and seal ring 2 cambered surface-Rd form sealing pair.Seal ring 10 is fixed in the seal groove of valve body 1 by trim ring 11, and trim ring 11 is connected by screw with valve body 1, after the sealing cambered surface of butterfly plate 9 and valve seat insert 10 are fitted, forms sealing pair, blocks fed sheet of a media.After the sealing cambered surface of butterfly plate 9 lifts off a seat seal ring 10, connect fed sheet of a media.
There is the adpting flange at same axis valve body 6 left side of the present utility model, right-hand member is that a telescopic tube 3(is flanged), carry out spacing with pull bar 5 and nut 5, at the position retractable installed and limiting in using process, valve and pipeline can adopt bolt and nut to be connected.
The butterfly valve series product of the three sections of circular arc sealings of the utility model butterfly plate band, an end band creeping flange can meet the usage requirement of the different latus rectum of cities and towns water drainage-supply system and different pressures.
