Abstract
The utility model relates to a ceramic butterfly valve. The ceramic butterfly valve comprises a valve body, a butterfly plate, a valve rod, a valve base, a transmission mechanism, a sealing member and a mounting member, wherein an eccentric structure is arranged among the valve body, the butterfly plate and the valve rod, and sealing faces matched with each other are arranged between the valve base and the butterfly plate. The ceramic butterfly valve is characterized in that the valve base is made of ceramic and is arranged on the valve body through a valve base pressing ring, and a ceramic sealing ring is arranged on the butterfly plate through a pressing plate to form a butterfly plate sealing face. The ceramic butterfly valve has the advantages of being resistant in high temperature, resistant in corrosion, resistance in abrasion, resistant in washing, stable and reliable in product sealing performance, long in service life and the like. The ceramic butterfly valve is suitable for valves of conveying pipes for high-abrasion media such as ore pulp, dreg pulp, sewage and grout.
Description
Technical field
The utility model belongs to valve field, particularly about a kind of butterfly valve.The utility model is applicable to the valve of ore pulp, slag slurry, sewage, the contour wear medium conveyance conduit of slurries.
Background technique
Butterfly valve is as a kind of pipeline valve, compare with the bore valve have in light weight, volume is little, consumptive material is economized, installation dimension is little, driving moment is little, characteristics such as easy and simple to handle, be widely used on the production technology pipeline of industries such as electric power, iron and steel, papermaking, petrochemical industry.Butterfly valve has hard sealing structure and soft sealing structure, and hard seal butterfly valve can be used in the high temperature media operating mode, has high temperature resistant, abrasion resistance properties.But, when using to be used as in high wear medium, hard seal butterfly valve regulates or during throttle valve, in the moment of closing or opening, velocity of medium is very fast, and the butterfly plate sealing surface is wearing and tearing fast easily, and sealability instability, working life are short.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, provides that a kind of sealability is stable, the Ceramic butterfly gate of long service life.
The technical solution of the utility model comprises valve body, butterfly plate, valve rod, valve seat, driving mechanism, Sealing and assembling set, be three eccentric structures between valve body, butterfly plate, the valve rod three, has the sealing surface that cooperatively interacts between valve seat and the butterfly plate, mainly be that valve seat adopts ceramic valve seat to be installed on the valve body by the valve seat trim ring, the butterfly plate sealing surface is installed on the butterfly plate by pressing plate by the ceramic seal circle to be formed.
In above technological scheme, sealing surface of seat and butterfly plate sealing surface are the sphere that cooperatively interacts.
In above technological scheme, valve seat adopts floating valve seat, and described floating valve seat is formed for the flexible adjustment circle is set between valve seat and valve seat trim ring.
In above technological scheme, the butterfly plate sealing surface is provided with automatic control tegulatingdevice, and described automatic control tegulatingdevice adopts flexible adjustment pad composition is set between butterfly plate and ceramic seal circle.
The utility model has the advantages that valve seat and butterfly plate sealing surface adopt stupalith, high temperature resistant, corrosion-resistant, wear-resistant, abrasion resistance can be good, and product hermeticity can reliable and stable, long service life.
