Description
Technical field
The invention belongs to ceramic ball valve technical field, more particularly to a kind of composite ceramics spheroid for high-pressure ceramic ball valve
And preparation method thereof.
Background technology
Ceramic ball valve is due to ceramic material deflection very little, and bond strength is higher, therefore with good pull resistance, resistance to compression
Property, wearability and corrosion resistance, with the development and progress of ceramic material in recent years, solve ceramic material more crisp not substantially
Foot, makes the toughness and intensity of ceramic material be greatly improved, progressively instead of metal ball-valve, solve metal ball-valve easy
Leakage, moment of torsion are big, sealing surface intolerant to the shortcoming that burn into reliability is low, service life is short, along with the raw material of manufacture ceramics is wide
It is general, it is with low cost, greatly save metal material and rare mineral resources, therefore ceramic ball valve is widely used in electricity
The industrial circles such as power, oil, chemical industry, metallurgy, mining, sewage disposal, especially in face of high abrasion, deep-etching, high temperature, high pressure etc.
Harsh environments, ceramic ball valve more shows its remarkable performance.Spheres of ceramic as ceramic ball valve important component,
Directly affect the quality of ceramic ball valve and use, ceramic ball valve currently on the market is broadly divided into pure spheres of ceramic ceramic ball valve
With steel ball blank ceramic ball valve, pure spheres of ceramic ceramic ball valve has good integrity, advantage easy to install, but can not hold
By larger open and close torque and the intensity of pressure；The spheres of ceramic made with steel ball blank, with higher intensity and reliably
Property, this spheres of ceramic is that ceramic inner sleeve is installed in steel ball blank, and ceramic empiecement is installed outside steel ball blank, is made
All parts contacted with medium are ceramic material, however this spheres of ceramic due to install ceramic material when can produce compared with
Many gaps, not only make spheres of ceramic processing become complicated, and can not ensure that ceramic material and steel ball blank are close
With reference in addition, although the self lubricity of ceramic material can reduce the opening and closing moment of torsion of valve, but it still can not meet valve rod base
The requirement of moment of torsion is transmitted to spheres of ceramic.
The content of the invention
Present invention aims to overcome that the deficiencies in the prior art and provide and a kind of being answered for high-pressure ceramic ball valve
Spheres of ceramic and preparation method thereof is closed, the ceramic material on spheres of ceramic is solved and does not allow easy to install, ceramic material and steel ball
Body combination is not close, and valve rod base transmits the insecure problem of moment of torsion to spheres of ceramic.
What the present invention was realized in：A kind of composite ceramics spheroid, including the ceramics set in steel cylinder, steel cylinder
Inner sleeve, the upper valve pole socket for being arranged on steel cylinder upper end, the lower valve pole socket for being arranged on steel cylinder lower end, it is characterised in that：Pottery
Porcelain inner sleeve one end is provided with sphere head, and the ceramic inner sleeve other end is provided with ceramic coat, and ceramic coat is arranged on outside steel cylinder
Side, upper valve pole socket and lower valve pole socket and ceramic coat tight fit, upper valve pole socket bottom surface and lower valve pole socket bottom surface are provided with convex
Rise, steel cylinder outer surface is provided with the groove being meshed with projection.
Screw is provided with described upper valve pole socket and lower valve pole socket, is consolidated upper valve pole socket and lower valve pole socket by screw
Dingan County is on steel cylinder.
Bellmouth is provided with described ceramic coat.
The face that described upper valve pole socket and lower valve pole socket is contacted with ceramic coat is set to taper surface.
Described projection is key.
Described groove is key groove.
A kind of preparation method of composite ceramics spheroid, it is characterised in that：
Step 1）, steel cylinder select：Steel cylinder is selected according to ceramic ball valve nominal pressure and the size of nominal diameter
The steel grade of different intensity grades, to meet intensity requirement；
Step 2）, ceramic inner sleeve processing：Sphere head, other end connection ceramic coat are set in one end of ceramic inner sleeve；
Step 3）, ceramic coat processing：Bellmouth is offered on ceramic coat；
Step 4）, ceramic inner sleeve assembling：There is sphere from steel cylinder one end installation settings with hot cover process or adhesive
The ceramic inner sleeve at first end；
Step 5）, ceramic coat assembling：Have with hot cover process or adhesive from the other end installation settings of steel cylinder
The ceramic coat of coniform hole；
Step 6）, upper valve pole socket, lower valve pole socket assembling：Screw is provided with steel upper valve pole socket and lower valve pole socket, is led to
Screw is crossed to be fixedly connected with steel cylinder, meanwhile, by the taper surface and ceramic coat of steel upper valve pole socket and lower valve pole socket
Bellmouth is fitted close；
Step 7）, key assembling：By the raised key of steel upper valve pole socket and steel lower valve pole socket bottom surface and steel cylinder appearance
The key groove intermeshing in face.
The present invention has following good effect：
1st, because composite ceramics spheroid uses steel cylinder as steel ball blank, therefore high strength steel can be selected
Manufacture high pressure, the intensity requirement of big-diameter ball valve are met, while ceramic inner sleeve and ceramic coat link together, makes spheres of ceramic
Globality is stronger, it is easy to the installation of ceramic ball valve, improves the deficiency that existing spheres of ceramic is present；
2nd, ceramic inner sleeve and ceramic coat not only can be using hot cover process assemblings, and can use the gluing dress of adhesive
Match somebody with somebody, ceramic inner sleeve, ceramic coat is combined with steel ball even closer, assemble relatively reliable；
3rd, because ceramic coat is an entirety, spheres of ceramic surface is made there was only one of seam, than spheres of ceramic before
Many slit designs are simpler, and intensity is higher, and processing also more facilitates；
4th, upper valve pole socket and lower valve pole socket and the close-fitting face of ceramic coat are set to taper surface, upper and lower valve rod base
Bellmouth on taper surface and ceramic coat is fitted close so that the combination of ceramic coat and steel cylinder is even closer and jail
Gu；
5th, the keyway intermeshing of the key of upper and lower valve rod base and steel ball, so as to be more beneficial for valve rod base to Ceramic Balls
Body transmits moment of torsion.
