Description
Technical field
The present invention relates to butterfly valve field, particularly to a kind of high-performance metal hard seal butterfly valve.
Background technology
Current modal hard seal butterfly valve is three eccentricity multilayered structure, and butterfly valve seat is positioned on valve body and non-disconnectable
Point, unadjustable；Sealing ring is lamellar stainless steel coil and graphite is composited；Sealing ring is solid with butterfly plate by pressing plate and screw
Fixed；The maximum drawback of this structure is: valve uses the initial stage, and sealing property is preferable, but it is continuous to sealing ring to be as medium
Washing away, cause graphite to come off, cause valve leak, the inefficacy of sealing ring causes whole valve to change, and wastes resource, also
Substantially increase maintenance cost；Further, since can use at high temperature under high pressure, have the generation of leakage the most unavoidably, the most such as
What reduces slip as far as possible, improves the security performance of valve, all has much room for improvement and perfect.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of leakage is low, the life-span is long, and high-performance metal easy to maintenance is hard
Sealed butterfly valve.
For reaching above-mentioned purpose, technical scheme is as follows:
A kind of high-performance metal hard seal butterfly valve, including valve body, butterfly plate molectron, valve rod, valve seat, disc holder and gear
Circle；Described valve seat is fixed on valve interior wall by disc holder and interior hexagonal flush end holding screw, described valve seat and valve body phase
It is provided with metallic gasket between adjacent plane；
Described butterfly plate molectron includes butterfly plate, metal o-ring, sealing ring pad, pressing plate, soket head cap screw and location
Pin；One side end face of described butterfly plate is provided with groove, and sealing ring pad is arranged in groove, metal o-ring be arranged on butterfly plate and
Between pressing plate, metal o-ring is fixed by pressing plate by soket head cap screw.
In one embodiment of the invention, described valve seat and metal o-ring surface spraying weld or pile-up welding hard alloy.
In one embodiment of the invention, described valve interior wall is provided with arc-shaped slot, and described back-up ring is fixed on arc
In draw-in groove.
In one embodiment of the invention, described butterfly plate, metal o-ring and pressing plate are fixed by alignment pin.
By technique scheme, the invention has the beneficial effects as follows:
Valve seat and metal o-ring are made up of metal material completely, and surface spraying weld or pile-up welding hard alloy, have anti-
Wash away, wear-resistant, high temperature high voltage resistant, the advantage of length in service life, even if opening and closing frequently, valve appoints the sealing that so can keep high
Can, stop the drawbacks such as Multi-layer sealing structure not resistance to erosion, drastically increase the service life of valve.
Valve body and valve seat are independent, and metal o-ring and butterfly plate on butterfly plate are also independent, so valve seat and butterfly plate
On metal o-ring can change, when the metal o-ring on butterfly plate or valve seat are impaired, it is not necessary to complete machine valve more simultaneously
Scrap, it is only necessary to change metal o-ring or valve seat, greatly reduce maintenance cost, also greatly reduce maintenance man-hours and inspection
Repair intensity and difficulty
Valve seat is detachable with valve body, is, by adjusting the thickness of described metallic gasket, to ensure sealing surface in valve assembling
Between seal pressure, thus the two way seal of complete machine valve is effectively ensured.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Conjunction is specifically illustrating, and the present invention is expanded on further.
See shown in Fig. 1 and Fig. 2, the invention discloses a kind of high-performance metal hard seal butterfly valve, including valve body 10, butterfly plate
Molectron, valve rod 20, valve seat 30, disc holder 40 and back-up ring 50；Valve seat 30 is tight by disc holder 40 and interior hexagonal flush end
Determine screw 60 to be fixed on valve interior wall, between valve seat 30 and the adjacent plane of valve body 10, be provided with metallic gasket 70, rise to seal and make
With；Simultaneously by adjusting the thickness of described metallic gasket, ensure the seal pressure between sealing surface, thus complete machine is effectively ensured
The two way seal of valve.
Valve interior wall is provided with arc-shaped slot, and back-up ring 50 is fixed in arc-shaped slot, plays the work of fixed valve base pressing plate 40
With, simultaneously facilitate maintenance and dismounting.
