Abstract
A double-eccentricity all-metal seal butterfly valve comprises a valve body, a valve plate, a valve shaft, a disc spring type metal valve seat, an O-shaped elastic metal ring and a gland. The valve body and the valve plate are arranged in an eccentric manner, the disc spring type metal valve seat is fixed to the valve body through the gland, and the O-shaped elastic metal ring is arranged between the disc spring type metal valve seat and the valve body. The disc spring type metal valve seat is adopted in the double-eccentricity all-metal seal butterfly valve, the extending length within unit size is increased, so that elastic deformation of the valve seat during work is increased, and plastic deformation of the valve seat is reduced. Meanwhile when the valve works in the reverse direction, the O-shaped elastic metal ring can absorb part of deformation of the valve seat caused by medium pressure, so that the service life of the valve is greatly prolonged.

Double eccentric butterfly valve is also called high-performance butterfly valve, is mainly applicable to the System drainage use such as water factory, power plant, steel mill's smelting, chemical industry, water source spring engineering, environmental facility construction, is particularly useful on water channel pipeline, as regulating and the equipment use of damming.Compare with centre-pivoted butterfly valve, double eccentric butterfly valve is more high pressure resistant, and the life-span is longer, good stability.Compare with other valve, the larger material of bore is lighter, and cost is the end more just.But due to the restriction of its material, in the application of high temperature, high pressure, deep-etching liquid medium transportation art, be very restricted.
The metallic sealing butterfly valve in the past conventionally adopting in high temperature, high pressure, deep-etching liquid medium transportation art mostly is three eccentric designs, all very high at each side costs such as design, processing, assemblings; Seat design is multilayer metal foil, nonmetallic material interval is used in every layer of employing, could realize the conveying of high temperature, high pressure, deep-etching liquid, and because three eccentric designs are complicated, once reveal, must be keeped in repair by professional workforce, maintenance cost is large, and the manufacturing cost of three eccentric butterfly valve is expensive, and cost is higher.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of two eccentric full metal seal butterfly valves that are applicable on high temperature, high pressure, deep-etching liquid medium conveyance conduit.
For achieving the above object, technological scheme provided by the invention is:
An eccentric full metal seal butterfly valve, comprises valve body, valve plate, valve shaft, disk spring type metal seat valve, metallic elastic O shape ring and gland; Described valve body and valve plate are set for the eccentric, and described gland is fixed on disk spring type metal seat valve on valve body, and between disk spring type metal seat valve and valve body, are provided with metallic elastic O shape ring.
Further, described disk spring type metal seat valve comprises fixing part, depressed part and the lug boss that integral type arranges, and described fixing part is fixed between valve body and gland, and described depressed part and metallic elastic O shape ring are equipped with, described lug boss and depressed part are adjacent, and are close to valve plate setting.
Further, between described fixing part and valve body and gland, be provided with sealing gasket.
Further, be also provided with gland fixing device on described gland, described gland fixing device is fixed on gland on valve body.
Further, on described valve shaft, be provided with bearing housing, described bearing housing top is provided with shaft sealer.
Further, described valve plate is fixed by a pin on valve shaft.
Further, also comprise differential, described differential is fixed on valve body by standard piece.
Further, described valve shaft top is fixed with drive unit link.
Adopt technique scheme, beneficial effect of the present invention has:
(1) low, the long service life, easy to maintenance of the provided by the present invention pair of eccentric full metal seal butterfly valve cost.
(2) the present invention adopts disk spring type metal seat valve, has increased the extended length in unit sizes, thereby has increased the resiliently deformable of valve seat when work, has reduced its plastic deformation; Metallic elastic O shape ring can absorb a part because of the valve seat distortion that pressure medium causes when valve reverse operation simultaneously, has extended greatly the working life of valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is A portion detailed drawing in Fig. 1.
Wherein: 1 valve body, 2 valve plates, 3 valve shafts, 4 disk spring type metal seat valves, 41 fixing parts, 42 depressed parts, 43 juts, 5 metallic elastic O shape rings, 6 glands, 7 sealing gaskets, 8 gland fixing devices, 9 bearing housings, 10 shaft sealers, 11 pins, 12 standard piece, 13 drive unit links, 14 differentials, 15 differential covers.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 is structural representation of the present invention, and as shown in Figure 1, a kind of pair of eccentric full metal seal butterfly valve, comprises valve body 1, valve plate 2, valve shaft 3, disk spring type metal seat valve 4, metallic elastic O shape ring 5 and gland 6; Described valve body 5 and valve plate 4 are set for the eccentric, and described gland 9 is fixed on disk spring type metal seat valve 7 on valve body 4, and between disk spring type metal seat valve 7 and valve body 4, are provided with metallic elastic O shape ring 5.On described valve shaft 3, be provided with bearing housing 9, described bearing housing 9 tops are provided with shaft sealer 10.Described valve plate 2 is fixed on valve shaft 3 by pin 11.The differential 14 that is provided with differential cover 15 is fixed on valve body 1 by standard piece 12, and valve shaft 3 tops are fixed with drive unit link 13, is used for being connected and realizing valve opening and closing with drive unit.
Wherein, the installation details of disk spring type metal seat valve 4 and metallic elastic O shape ring 5 as shown in Figure 2, described disk spring type metal seat valve 4 comprises fixing part 41, depressed part 42 and the lug boss 43 that integral type arranges, described fixing part 41 is fixed between valve body 1 and gland 6, described depressed part 42 is equipped with metallic elastic O shape ring 5, described lug boss 43 is adjacent with depressed part 42, and is close to valve plate 2 settings.In addition, between described fixing part 41 and valve body 1 and gland 6, be provided with sealing gasket 7.On described gland 6, be also provided with gland fixing device 8, described gland fixing device 8 is fixed on gland 6 on valve body 1.
Provided by the present invention pair of eccentric full metal seal butterfly valve, while working under positive pressure, valve seat moves with the displacement of valve plate, guarantees sealability; While working under backpressure, valve seat displacement with valve plate under the effect of pressure is moved, thereby metallic elastic O shape ring absorption portion valve seat amount of deformation guarantees that valve seat does not produce plastic deformation and guarantees sealability simultaneously.Adopt disk spring type metal seat valve, increased the extended length in unit sizes, thereby increased the resiliently deformable of valve seat when work, reduced its plastic deformation; Metallic elastic O shape ring can absorb a part because of the valve seat distortion that pressure medium causes when valve reverse operation simultaneously, has extended greatly the working life of valve.
