Modular pottery ball core in the high -voltage ceramic ball valve makes ceramic ball valve also can be used in the poor operational environment of high pressure, enlarges ceramic ball valve's application range.
Description
Technical field
This utility model belongs to universal machine valve technology field, more particularly to a kind of in high-pressure ceramic ball valve
Combined ceramic core.
Background technology
Ball valve (ball valve) is to be developed by plug valve (plug valve), and its opening and closing element is as one
Spheroid, rotates 90 °, around the axis of valve rod, the purpose realized valve opening and close using spheroid.Ball valve is not only simple in structure, close
Sealing property is good, and in the range of certain inside nominal diameter small volume, lightweight, material consumption is few, installation dimension is little, have
Minimum circulating resistance, ball valve and to have a driving torque little, easy and simple to handle, the advantages of easily realize fast opening and closing, it is nearly more than ten
One of valve kind with fastest developing speed over year.Particularly in industrially developed country such as America and Japan De Fayixiying, ball valve using non-
Often extensive, the kind of use and quantity still continuing to expand, and to high temperature, high pressure, heavy caliber, high leakproofness, the long-life, excellent
Regulation performance and valve multifunctional direction development, its reliability and other performance indications all reach higher level, and
Part instead of gate valve, stop valve, regulating valve etc. and is applied to various working sites.
But existing metal material ball valve, due to the restriction of the aspects such as material, structure, for severe corrosive or contain
High rigidity solid particle medium, sometimes using there are a lot of problems under two kinds of operating modes having both at the same time, valve service life is short,
Have impact on the normal business activities of production, therefore occur in that the ceramic ball valve of many in the market.Due to structural ceramic material
Although hardness is high, abrasion and corrosion resistance is good, belongs to fragile material after all, and comprehensive mechanical intensity hardly matches metal, so
Common ceramic ball valve mostly is conventional design, and pressure rating is low, also have impact on promoting the use of of ceramic ball valve.
Utility model content
The purpose of this utility model be improve prior art deficiency, provide a kind of for the group in high-pressure ceramic ball valve
Box-like pottery core, makes ceramic ball valve also can be used in the working environment of High Pressure Difference, expands the group of the range of ceramic ball valve
Box-like pottery core.
For realizing this utility model purpose, there is provided technical scheme below: a kind of Combined ceramic core, including Ceramic Balls
Core body, it is opened in the runner of Ceramic Balls core-center, is symmetrically opened in Ceramic Balls core body upper and lower side valve rod blind hole and short axle blind hole,
It is characterized in that valve rod blind hole embeds is connected to the flat set of metal valve stem, short axle blind hole embeds and is connected to metal short axle circle set, metal valve stem
Flat set and valve rod blind hole interference fit, it is bonding with valve rod blind hole that metal valve stem flat set outer surface is coated with glue, metal short axle circle
Set and short axle blind hole interference fit, it is bonding with short axle blind hole that metal short axle circle set outer surface is coated with glue.
Preferably, runner is " o " type through hole or " v " the type through hole meeting the requirement of certain flow coefficient adjustment.
Preferably, Ceramic Balls core body is zirconia ceramicss or aluminium oxide ceramics or alumina toughened zircon pottery.Than
The metal material that anharmonic ratio is commonly used is light, and coefficient of friction when keying is little
Preferably, Ceramic Balls core body upper and lower end is plane.
Preferably, Ceramic Balls core body sphere diameter is than the sphere diameter ratio more than metal core, ratio >=2.
This utility model beneficial effect: general structure design is short and sweet, it is to inlay on Ceramic Balls core body first
The flat set of valve rod and short axle garden set that metal is made, indirectly increase the contact area of valve rod drive end and core, are Ceramic Balls
The moment of torsion that core can bear increases；Due to valve rod, short axle and respectively with the valve rod that they use cooperatively flat set, short axle garden set be all
Metal material, reduces the abrasion of valve rod；The runner of core is " o " type through hole or meets the requirement of certain flow coefficient adjustment
" v " type through hole, makes the purposes of ball valve more extensive；Sphere diameter than the sphere diameter ratio much larger than metal core, ratio >=2, can be further
The bulk strength ensureing ceramic core；Design short axle garden set hole is that float ball design is changed to fixing ball, be so unlikely to because
For working site High Pressure Difference, large effect is caused to valve torque, so that valve is driven steadily reliable；Will be flat for the valve rod of core body
Set hole and short axle garden set hole are designed as blind hole structure, are that valve medium when compared with small guide vane is very big to the erosion of valve rod, improve valve
The service life of bar.
Therefore, this utility model be capable of ceramic valve by low pressure striding to high pressure, better meet different uses
The technical requirements at scene, expand the range of ceramic ball valve, can greatly improve the economical production scale of enterprise, reduce into
This, obtain good economic benefit.
