Description
Technical field
The invention belongs to valve method field of manufacturing, be specifically related to a kind of technique of utilizing composite ceramic material fabricator valve.
Background technology
Valve is generally made up of the valve internals of valve body and valve inner, can be divided into metal valve, Plastic valve and ceramic valve according to manufactured materials.
In production technology and technique, comparatively ripe in family expenses valve is metal valve, on market, comparatively common are stainless valve and copper valve, in the product of low side, also there is cast iron valve a little, but there is considerable defect in metal valve, metal valve is in life-time service process, extremely easily there is the problems such as burn into gets rusty, plating exfoliation, can penetrate into gradually in domestic water for the manufacture of the heavy metal such as lead, tin in the alloy of metal valve, domestic water is polluted, directly affect the healthy of people.
Although Plastic valve can be by injection moulding, do dimensionally very accurately, there is easily aging problem in plastics, compensation duration of service; And due to Shooting Technique, be difficult to manufacture the baroque product of boring, cause Plastic valve to be difficult to extensively promote in family expenses valve.
If use ceramic valve as family expenses valve, not only ceramic plasticity-is strong, quality is hard, it is aging to be difficult for, and uses health, environmental protection.But conventional ceramic quality is more crisp, because the connection portion at each parts is very fragile, in use procedure, there is the risk that injures human body in easily fracture.The ceramic valve of selling in the market has all adopted the valve internals of metal, but the poor stability of product, difficult forming, junction is more prone to fracture; And the manufacturing process of existing ceramic valve is comparatively complicated.
Therefore, developing a kind of manufacturing process that can manufacture hygienic environment-protecting, long-lived ceramic valve, is the new problem of the required research of those skilled in the art.
Summary of the invention
In order to address the above problem, the invention provides a kind of manufacturing process of composite ceramics family expenses valve, the family expenses valve hygienic environment-protecting manufactured by this technique, durable in use.
In order to achieve the above object, the invention provides following technical scheme:
A manufacturing process for composite ceramics family expenses valve, concrete steps are:
(1) be ready to valve body material and valve internals material, according to structure, shape and the size of the selected valve body of real needs and valve internals, prepare Valve Block Mould and valve internals mould;
(2) will in valve body material, drop in ball mill, and add auxiliary material, mix, and at the roasting temperature 1.5-2h of 1450-1850 DEG C, after roasting completes, carry out coolingly, form valve body idiosome material;
(3) valve body idiosome material is plastified, after having plastified, import in Valve Block Mould; By hot chamber machine, valve body idiosome material is carried out to die casting, and carry out pressurize;
(4) the valve body idiosome material processing in step (3) is carried out to cooling, the demoulding, make valve body idiosome;
(5) valve body idiosome is carried out to degreasing, cooling, glazing;
(6) by sinter molding equipment, valve body idiosome is carried out to sintering, obtain valve body after cooling;
(7) will in valve internals material, drop in ball mill, and add auxiliary material, mix, and at the roasting temperature 1.5-2h of 1150-1550 DEG C, after roasting completes, carry out coolingly, form valve internals idiosome material;
(8) valve internals idiosome material is plastified, after having plastified, import in valve internals mould, carry out die casting by hot chamber diecasting and to valve internals idiosome material, and carry out pressurize;
(9) the valve internals idiosome material processing in step (8) is carried out to cooling, the demoulding, make valve internals idiosome;
(10) valve internals idiosome is carried out to degreasing, cooling, glazing;
(11) by sinter molding equipment, valve internals idiosome idiosome is carried out to sintering, obtain valve internals after cooling;
(12) valve body and valve internals are assembled into valve according to principle from inside outwards, from bottom to top.
In method provided by the invention, first need to prepare to manufacture the material of valve body and valve internals, and make as required Valve Block Mould and valve internals mould.
First ready valve body material is put into ball mill, utilize ball mill that valve body material is pulverized completely, then add auxiliary material and mix and carry out roasting, cooling rear formation valve body idiosome material, products for further processing; After valve body idiosome material completes, plastify and import Valve Block Mould, die casting, pressurize, cooling, the demoulding obtain valve body idiosome; Again to the valve body idiosome degreasing obtaining, cooling, glazing, sintering, obtain valve body after again cooling.
In like manner can make valve internals by above step.
Be assembled into valve according to principle from inside outwards, from bottom to top again.
As preferably, moiety and the shared mass percent of each composition of valve body material and valve internals material are: TiO
2: 45-60%, Al
2o
3: 30-40%, SiO
2: 5-20%.
Use TiO
2, Al
2o
3with SiO
2the composite ceramic material of composition valve body material and valve internals material, can show for lower than 2.8X10
-6(1/K) thermal expansivity, the porosity of the volumeter at least 31% in the space, hole of composite ceramics main body, and there is the flexural strength that is greater than about 8.5MPa.
As preferably, the moiety of auxiliary material and the shared mass percent of each composition are: binding agent: 40-60%, fluidizer: 20-40%, dispersion agent: 10-20%.
Use binding agent can improve cohesive strength between composite ceramics abrasive material; Add fluidizer and can make the snappiness of composite ceramics abrasive material strengthen, easily processing; Dispersion agent can be after composite ceramics abrasive material plastifies, and removes fixing impurity particle, promotes the gloss of composite ceramics.
As preferably, valve body material and valve internals material also comprise the steatite ceramic gatch of liquefaction.
After steatite ceramic gatch is melted, be added to valve body material and valve internals material, not only make valve body material and valve internals material in ball mill, be more prone to grind, the while can also promote the gloss of composite ceramics valve finished product, strengthens that it is attractive in appearance.
Compared with the production technique of the present invention and existing valve production technique and existing ceramic valve, use composite ceramics fabricator valve, hygienic environment-protecting; And use novel stupalith to make valve body and valve internals, make finished product there is lower thermal expansivity, suitable porosity and higher flexural strength, make composite ceramics family expenses valve durable in use.
