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

Ceramic butterfly gate
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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of butterfly plate among the utility model Fig. 1.
Fig. 3 is the structure enlarged view that valve seat and butterfly plate sealing surface cooperatively interact among the utility model Fig. 1.
Embodiment
Ceramic butterfly gate as shown in Figure 1, comprise valve body 1, butterfly plate 7, valve rod 8, valve seat 4, driving mechanism 13, Sealing and assembling set, be three eccentric structures between valve body 1, butterfly plate 7, valve rod 8 threes, has the sealing surface that cooperatively interacts between valve seat 4 and the butterfly plate 7, valve seat 4 adopts ceramic valve seat to be installed on the valve body 1 by valve seat trim ring 2, and the butterfly plate sealing surface is installed on the butterfly plate 7 by pressing plate 5 by ceramic seal circle 6 to be formed.Ceramic valve seat and ceramic seal circle 6 adopt engineering ceramic material, have high temperature resistant, corrosion-resistant, wear-resistant, abrasion resistance energy.
Valve seat 4 sealing surfaces and butterfly plate sealing surface are the sphere that cooperatively interacts.Both valve seat 4 sealing surfaces had the identical circular arc camber concentric with valve rod 8 centers of circle with ceramic seal circle 6, were linear sealing to improve sealability, as shown in Figure 2 under the state of being sealed and matched.
Valve seat 4 adopts floating valve seat, and described floating valve seat is formed for flexible adjustment circle 17 is set between valve seat 4 and valve seat trim ring 2.Stressed when big when valve seat 4, can realize compensation automatically by the resiliently deformable of flexible adjustment circle 17, satisfy seal request, as shown in Figure 3.
The butterfly plate sealing surface is provided with automatic control tegulatingdevice, and described automatic control tegulatingdevice adopts flexible adjustment pad 16 compositions are set between butterfly plate 7 and ceramic seal circle 6, and as shown in Figure 2, flexible adjustment pad 16 is installed in the circular groove in butterfly plate 7 planes.Utilize the elasticity of flexible adjustment pad 16, regulate the ceramic seal circle 6 of butterfly plate 7 and the sealing state between the valve seat 4 automatically.
Driving mechanism 13 is fixedly mounted on the valve body 1 by support 12, and valve rod 8 upper ends are connected with the output shaft of driving mechanism 13, and the lower end is installed in the valve body 1 by axle sleeve 3.Adopt filler 9 sealings between valve rod 8 middle parts and the valve body 1, this filler 9 is sealed in the packing cavity that is installed between valve body 1 and the valve rod 8 by bolt 14, nut 15 by filler pressing 10 and Gland 11.
