Description
Technical field
The invention belongs to valve manufacture method field, be specifically related to a kind of technique 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, market comparatively common are stainless valve and copper valve, also cast iron valve is had in the product of low side 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 in domestic water gradually for the manufacture of heavy metals such as the lead in the alloy of metal valve, tin, domestic water is polluted, directly affects the healthy of people.
Although Plastic valve can pass through injection moulding, doing very accurate dimensionally, there is easily aging problem in plastics, and duration of service compensates; 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, not easily aging, and uses health, environmental protection.But conventional ceramic quality is more crisp, because the connection portion at each parts is very fragile, easily rupture in use procedure, there is the risk of injury human body.The ceramic valve sold in the market all have employed 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 solve the problem, the invention provides a kind of manufacturing process of composite ceramics family expenses valve, by the family expenses valve hygienic environment-protecting of this manufacture technics, 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) get out valve body material and valve internal materials, select the structure of valve body and valve internals, shape and size according to real needs, prepare Valve Block Mould and valve internals mould;
(2) drop in valve body material in ball mill, and add auxiliary material, mix, and at the roasting temperature 1.5-2h of 1450-1850 DEG C, cool after roasting completes, form valve body idiosome material;
(3) valve body idiosome material is plastified, import in Valve Block Mould after having plastified; By hot chamber machine, die casting is carried out to valve body idiosome material, and carry out pressurize;
(4) the valve body idiosome material processed in step (3) is cooled, the demoulding, obtained valve body idiosome;
(5) degreasing, cooling, glazing are carried out to valve body idiosome;
(6) by sinter molding equipment, valve body idiosome is sintered, after cooling, obtain valve body;
(7) drop in valve internal materials in ball mill, and add auxiliary material, mix, and at the roasting temperature 1.5-2h of 1150-1550 DEG C, cool after roasting completes, form valve internals idiosome material;
(8) valve internals idiosome material is plastified, import in valve internals mould after having plastified, carry out die casting by hot chamber diecasting and to valve internals idiosome material, and carry out pressurize;
(9) the valve internals idiosome material processed in step (8) is cooled, the demoulding, obtained valve internals idiosome;
(10) degreasing, cooling, glazing are carried out to valve internals idiosome;
(11) by sinter molding equipment, valve internals idiosome idiosome is sintered, after cooling, obtain valve internals;
(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 the material preparing to manufacture valve body and valve internals, and make Valve Block Mould and valve internals mould as required.
First ready valve body material is put into ball mill, utilize ball mill to be pulverized completely by valve body material, then add auxiliary material and mix and carry out roasting, form valve body idiosome material after cooling, products for further is processed; After valve body idiosome material completes, carry out plasticizing and import Valve Block Mould, die casting, pressurize, cooling, the demoulding obtain valve body idiosome; Again to the valve body idiosome degreasing obtained, cooling, glazing, sintering, again obtain valve body after cooling.
In like manner can obtain valve internals by above step.
Valve is assembled into again according to principle from inside outwards, from bottom to top.
As preferably, shared by the moiety of valve body material and valve internal materials and each composition, mass percent is: TiO
2: 45-60%, Al
2o
3: 30-40%, SiO
2: 5-20%.
Use TiO
2, Al
2o
3with SiO
2composition valve body material and the composite ceramic material of valve internal materials, 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 being greater than about 8.5MPa.
As preferably, shared by the moiety of auxiliary material and each composition, mass percent is: binding agent: 40-60%, fluidizer: 20-40%, dispersion agent: 10-20%.
Use binding agent can improve cohesive strength between composite ceramics abrasive material; Adding fluidizer can make the snappiness of composite ceramics abrasive material strengthen, and easily processes; Dispersion agent after composite ceramics abrasive material plastifies, can be removed fixing impurity particle, promotes the gloss of composite ceramics.
As preferably, valve body material and valve internal materials also comprise the steatite ceramic gatch of liquefaction.
Be added to valve body material and valve internal materials after being melted by steatite ceramic gatch, not only make valve body material and valve internal materials be more prone to grind in ball mill, while can also promote the gloss of composite ceramics valve finished product, strengthen 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 have lower thermal expansivity, suitable porosity and higher flexural strength, make composite ceramics family expenses valve durable in use.
