Description
Technical field
The invention belongs to ceramic ball valve technical field, particularly relate to a kind of composite ceramics spheroid for high-pressure ceramic ball valve and preparation method thereof.
Background technique
Ceramic ball valve due to stupalith amount of deformation very little, adhesive strength is higher, therefore there is good pull resistance, crushing resistance, wear resistance and corrosion resistance, along with the development and progress of stupalith in recent years, substantially the deficiency that stupalith is more crisp is solved, the toughness of stupalith and intensity are greatly improved, progressively instead of metal ball-valve, solve metal ball-valve easily to leak, moment of torsion is large, sealing surface is not corrosion-resistant, reliability is low, the shortcoming that working life is short, add the raw material manufacturing pottery extensive, with low cost, metallic material and rare mineral resources are greatly saved, therefore ceramic ball valve is widely used in electric power, oil, chemical industry, metallurgical, mining, the industrial fields such as sewage treatment, especially in the face of high wearing and tearing, deep-etching, high temperature, the harsh environments such as high pressure, ceramic ball valve more demonstrates the performance of its brilliance.Spheres of ceramic is as the important component part of ceramic ball valve, directly affect quality and the use of ceramic ball valve, now ceramic ball valve commercially is mainly divided into pure spheres of ceramic ceramic ball valve and steel ball blank ceramic ball valve, pure spheres of ceramic ceramic ball valve has good integrity, the advantage of easy installation, but larger open and close torque and the intensity of pressure can not be born, with the spheres of ceramic that steel ball blank is made, there is higher intensity and reliability, this spheres of ceramic installs ceramic inner sleeve in steel ball blank, at steel ball blank, ceramic empiecement is installed outward, make allly to be stupalith with the part of medium contact, but this spheres of ceramic is owing to can produce more gap when installing stupalith, not only make spheres of ceramic process and become complicated, and cannot ensure that stupalith and steel ball blank combine closely, in addition, although the self lubricity of stupalith can reduce the opening and closing moment of torsion of valve, but still cannot meet the requirement of valve rod base to spheres of ceramic transmitting torque.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and provides a kind of composite ceramics spheroid for high-pressure ceramic ball valve and preparation method thereof, the stupalith solved on spheres of ceramic is not easy to install, stupalith and steel ball combine not tight, and valve rod base is to the insecure problem of spheres of ceramic transmitting torque.
The present invention is achieved in that a kind of composite ceramics spheroid, comprise steel cylinder, the ceramic inner sleeve arranged in steel cylinder, be arranged on the upper valve rod seat of steel cylinder upper end, be arranged on the lower valve rod seat of steel cylinder lower end, it is characterized in that: ceramic inner sleeve one end is provided with sphere head, the pottery inner sleeve the other end is provided with ceramic coat, ceramic coat is arranged on outside steel cylinder, upper valve rod seat and lower valve rod seat and ceramic coat closely cooperate, upper valve rod seat bottom surface and lower valve rod seat bottom surface are provided with projection, steel cylinder outer surface is provided with the groove be meshed with projection.
Described upper valve rod seat and lower valve rod seat are provided with screw, by screw, upper valve rod seat and lower valve rod seat are fixedly mounted on steel cylinder.
Described ceramic coat is provided with cone shape hole.
The face that described upper valve rod seat and lower valve rod seat contact with ceramic coat is set to conical surface.
Described projection is key.
Described groove is key groove.
A making method for composite ceramics spheroid, is characterized in that:
Step 1), steel cylinder are selected: steel cylinder selects the steel grade of different intensity grades, to meet requirement of strength according to the size of ceramic ball valve nominal pressure and nominal diameter;
Step 2), ceramic inner sleeve processing: in one end of ceramic inner sleeve, sphere head is set, the other end connect ceramic coat;
Step 3), ceramic coat are processed: on ceramic coat, offer cone shape hole;
Step 4), ceramic inner sleeve are assembled: install with hot cover process or tackiness agent the ceramic inner sleeve being provided with the first end of sphere from steel cylinder one end;
Step 5), ceramic coat assemble: install from the other end of steel cylinder the ceramic coat being provided with coniform hole with hot cover process or tackiness agent;
Step 6), upper valve rod seat, lower valve rod seat assemble: steel upper valve rod seat and lower valve rod seat are provided with screw, be fixedly connected with steel cylinder by screw, meanwhile, the cone shape hole on the conical surface of steel upper valve rod seat and lower valve rod seat and ceramic coat is closely cooperated;
Step 7), key assemble: steel upper valve rod seat and the key of steel lower valve rod seat bottom surface projection and the key groove of steel cylinder outer surface are engaged each other.
The present invention has following good effect:
1, because composite ceramics spheroid adopts steel cylinder as steel ball blank, therefore high tensile steel can be selected to meet the requirement of strength manufacturing high pressure, big-diameter ball valve, ceramic inner sleeve and ceramic coat link together simultaneously, make spheres of ceramic integrity stronger, be easy to the installation of ceramic ball valve, improve the deficiency that existing spheres of ceramic exists;
2, ceramic inner sleeve and ceramic coat not only can adopt hot cover process to assemble, and can use the gluing assembling of tackiness agent, ceramic inner sleeve, ceramic coat are combined with steel ball more tight, assemble more reliable;
3, because ceramic coat is as a whole, make spheres of ceramic surface only have one seam, more simpler than the many slit design of spheres of ceramic before, intensity is higher, processes also convenient;
4, upper valve rod seat and lower valve rod seat and the close-fitting face of ceramic coat are set to conical surface, the cone shape hole on upper and lower valve rod base conical surface and ceramic coat closely cooperates, and the combination making ceramic coat and steel cylinder more closely and firmly;
5, the key of upper and lower valve rod base and the keyway of steel ball engage each other, thus are more conducive to valve rod base to spheres of ceramic transmitting torque.
