Description
Technical field
The present invention relates to a kind of butterfly valve, particularly to the butterfly valve of a kind of double eccentric conical valve seat metal hard-sealings, belong to five metals
Hot-water heating technical field.
Background technology
Heat distribution pipe network, imflammable gas conveying, the flue gas of petrochemical industry and variousization of gas industry in power industry
Work raw material and the conveying of product, water utilities industry the large aperture tubing such as Hydraulic transportation in medium frequently opened and closes
To the valve installed, the occasion closed, requires that leakage is little, switching speed is fast.Butterfly valve kinetic energy aspect of the prior art relies on execution machine
The moment of torsion of structure makes valve plate close tighter and tighter closing when, and sealing member aspect relies on high polymer elastic sealing member and butterfly plate outer
Elastic Contact thus reach sealing effectiveness.But, some as high temperature, flue gas, solvent special occasions in, due to macromolecule
The limitation such as the heatproof of material, solvent resistant causes sealing member easily to damage and causes leakage etc., not only directly affects commercial production, makes
Become economic loss, be even also possible to cause security incident.
Summary of the invention
For solving big, the flimsy technical problem of sealing member, the present invention offer in the leakage of Special use environment of above-mentioned butterfly valve
A kind of butterfly valve of double eccentric conical valve seat metal hard-sealing.
The technical solution adopted in the present invention is: the butterfly valve of a kind of double eccentric conical valve seat metal hard-sealings, by valve body, holds
Row mechanism, butterfly plate and black box are constituted, and valve body is the connection supporting body of butterfly valve and inner chamber is spherical cavity structure, spherical cavity end
There are installation room, actuator include housing and drive assembly, drive assembly be arranged on housing and be arranged on valve body by housing
Above, butterfly plate includes butterfly plate body and valve rod, and the outer of butterfly plate body uses built-up welding stellite to constitute hard sealing surface, butterfly
The back side of plate body is joint face and is connected to valve rod by connecting elements, and valve rod is arranged on valve body and constitutes double eccentric, valve rod
Upper end extend for connection to drive assembly, black box include sealing ring, positioning pressuring plate, pendant collet sealing clamp and location spiral shell
Nail, sealing ring is formed by stacking and is arranged on the inside of installation room by the hard sealing ring of multiple layer metal, and positioning pressuring plate is arranged on sealing ring
Outside, pendant collet sealing clamp is arranged on outside positioning pressuring plate and is positioned at valve body by location screw.
Double bias are that butterfly plate longitudinal axis deviates valve body longitudinal axis, the sealing axis runout valve rod axis of sealing surface.
The invention has the beneficial effects as follows: sealing ring is unlikely to deform by hard quoit multiple-layer stacked, and sealing ring is inlayed completely
At valve body, fluid only flows through from its side that to have extremely strong protection against erosion performance long for service life；Except the height with bi-direction zero-leakage
Outside sealing property, the advantage also with splendid low flow resistance coefficient.
Accompanying drawing explanation
The present invention is further described below in conjunction with the accompanying drawings:
Fig. 1 is lateral section and the local structure for amplifying schematic diagram of the present invention；
Fig. 2 is the cross-sectional structure schematic diagram of the present invention.
In figure 1, valve body, 2, actuator, 3, butterfly plate, 4, valve rod, 5, hard sealing surface, 6, sealing ring, 7, location pressure

Detailed description of the invention
In the embodiment in figure 1, the butterfly valve of a kind of double eccentric conical valve seat metal hard-sealings, by valve body 1, actuator 2,
Butterfly plate 3 and black box are constituted, and valve body 1 is the connection supporting body of butterfly valve and inner chamber is spherical cavity structure, and spherical cavity end has peace
Dress room, actuator 2 includes housing and drives assembly, drives assembly be arranged on housing and be arranged on the upper of valve body 1 by housing
Face, butterfly plate 3 includes butterfly plate body and valve rod 4, and the outer of butterfly plate body uses built-up welding stellite to constitute hard sealing surface 5,
The back side of butterfly plate body is joint face and is connected to valve rod 4 by connecting elements, and valve rod 4 is arranged on valve body 1 and constitutes double eccentric,
The upper end of valve rod 4 extends for connection to drive assembly, and black box includes sealing ring 6, positioning pressuring plate 7, pendant collet sealing clamp 8 and
Location screw 9, sealing ring 6 is formed by stacking and is arranged on the inside of installation room by the hard sealing ring of multiple layer metal, and positioning pressuring plate 7 is installed
In the outside of sealing ring 6, pendant collet sealing clamp 8 is arranged on outside positioning pressuring plate 7 and is positioned at valve body 1 by location screw 9.
In the embodiment of fig. 2, double bias are that butterfly plate longitudinal axis 10 deviates valve body longitudinal axis 11, the sealing axis of sealing surface
12 deviation valve rod axis 13.
Embodiment: sealing ring 6 is unlikely to deform by hard quoit multiple-layer stacked, sealing ring 6 is embedded in valve body 1 completely, stream
Body only flows through from its side that to have extremely strong protection against erosion performance long for service life；Except the high sealing performance with bi-direction zero-leakage
Outward, the advantage also with splendid low flow resistance coefficient.
