Abstract
A kind of high-performance desulfurization specialty butterfly valve, it includes valve body, valve seat, valve plate, valve rod, by being correspondingly improved design to valve body, valve seat, valve plate, valve rod, realizes reduction operational torque；Firm seat shape, it is to avoid the deformation of valve seat protuberance is torn；Ensure that valve plate and valve rod are reliably driven, valve is normally opened and closed, cause corrosion while preventing medium and directly being contacted with valve rod, extend valve shelf life.
Description
Technical field
The utility model is related to valve technology field, especially a kind of high-performance desulfurization specialty butterfly valve.
Background technology
Desulfurization butterfly valve is a kind of valve as unlatching, closing and regulation fluid passage.In use, desulfurization specialty
Some basic demand such as corrosion, wear, flow velocity, temperature must is fulfilled for butterfly valve, and the desulfurization at present applied to association area is special
There are some shortcomings with butterfly valve in industry：Operational torque is big；Valve seat is easily deformed tear；Valve plate and valve rod transmission are easily separated from, valve
Can not normally it open and close.Its particular problem is described as follows：The sealing surface of existing valve plate is plane, and operational torque is big, easy scratch
Valve seat；Valve seat is rubber back one layer thin directly against valve body, valve install and valve plate opening-closing process in, valve seat is by squeezing
Easily protuberance is deformed or torn for pressure and traction；The valve plate and valve rod of butterfly valve are driven by pin, and valve rod passes through pin when rotating
Drive valve plate to rotate, valve was used after a period of time, due to abrasion and dielectric corrosion, the easy loose or dislocation of pin, cause valve plate
Can not normally open and close, and corrosive medium can by pin hole directly and valve rod, valve body contact, cause the corruption of whole valve
Erosion, shortens service life.
The content of the invention
The purpose of this utility model is to provide a kind of high-performance desulfurization specialty butterfly valve, and it includes valve body, valve seat, valve
Plate, valve rod, by being correspondingly improved design to valve body, valve seat, valve plate, valve rod, realize reduction operational torque；Firm valve seat
Shape, it is to avoid the deformation of valve seat protuberance is torn；Ensure that valve plate and valve rod are reliably driven, valve is normally opened and closed, while preventing medium
Directly contacted with valve rod and cause corrosion, extend valve shelf life.
To reach above-mentioned purpose, the solution that the utility model is taken is：A kind of high-performance desulfurization specialty uses butterfly valve bag
Valve body, valve seat, valve plate, valve rod are included, sealing surface is processed and makes hemisphere face by the valve plate；The valve seat is by rubber and phenolic aldehyde material
Expect an entirety being sulfided into；Valve plate and valve rod connection are driven or used spline drived, i.e. valve plate and valve rod junction using plane
Plane cooperation is made, realizes and ensure that reliable transmission between the two；The valve seat and valve plate of butterfly valve are made using anti-corrosion material,
The only direct contact medium of valve seat and valve plate, other parts not with physical contact between media, it is to avoid corrosivity, extend valve
Service life.
Sealing surface is processed and makes hemisphere face by the valve plate of butterfly valve, is directly rubbed with valve seat by reducing sealing area,
So as to reduce the operational torque of valve, and frictionally damage of the valve plate to valve seat is alleviated, extend the service life of valve seat.
The valve seat of butterfly valve is an entirety being sulfided into by rubber and phenolic materials, and phenolic materials have certain hardness,
Valve seat support performance is good, stable and firm, is unlikely to deform, and the valve seat of monolithic devices is not easily susceptible to draw masterpiece in valve plate opening-closing process
With and tear, extend the service life of valve seat.
Brief description of the drawings
Fig. 1 is the front view of the present embodiment.
Fig. 2 is the sectional drawing of the present embodiment.
Fig. 3 is the structure chart of the present embodiment valve plate.
Fig. 4 is the structure chart of the present embodiment valve seat.
Fig. 5 is the present embodiment valve plate and valve rod transmission structure figure.
Marked in figure：1 valve body, 2 valve seats, 3 valve plates, 4 valve rods, 5 phenolic materials.
Embodiment
The utility model is described again with reference to embodiment and its accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3, a kind of high-performance desulfurization specialty includes valve body 1, valve seat 2, valve plate 3, valve rod 4 with butterfly valve,
Sealing surface is processed and makes hemisphere face by valve plate 1, is directly rubbed with valve seat 2 by reducing sealing area, so as to reduce valve
The operational torque of door, and frictionally damage of the valve plate 3 to valve seat 2 is alleviated, extend the service life of valve seat 2.
Referring to Fig. 4 and Fig. 5, the entirety that valve seat 2 is sulfided into by rubber and phenolic materials 5, phenolic materials 5 have certain
Hardness, the support performance of valve seat 2 is good, stable and firm, is unlikely to deform, the valve seat 2 of monolithic devices be difficult in the opening-closing process of valve plate 3 by
Act on and tear to tractive force, extend the service life of valve seat 2.Valve plate 3 and the connection of valve rod 4 are driven or used spline using plane
Plane cooperation is made in transmission, i.e. valve plate 1 and the junction of valve rod 3, it is ensured that reliable transmission between the two；The He of valve seat 2 of butterfly valve
Valve plate 3 is made using anti-corrosion material, only valve seat 2 and the direct contact medium of valve plate 3, and other parts do not connect directly with medium
Touch, it is to avoid corrosivity, extend the service life of valve.
