A kind of processing technology the present invention relates to valve with high intensity handle, belongs to valve arrangement technical field.The processing technology of the valve high intensity handle of the present invention includes：(i) handle body is made；(ii) obtained handle body is heat-treated；(iii) in handle body electroplating of Zn-Ni alloy onto surface coating；(iv) the method coating refractory coating for passing through atomizing spraying on the surface of handle body；(v) valve is checked one by one with high intensity handle, rejecting face coat is defective, will examine qualified storage.In processing technology of the valve of the present invention with high intensity handle, in the method coating refractory coating that the surface of handle body passes through atomizing spraying, there is one layer of refractory coating again outside the zn-ni alloy depositses of handle, so that handle not only has decay resistance, also it is provided with fire resistance, service life is substantially prolongs, ensure that the stabilization of work.
Description
Technical field
A kind of processing technology the present invention relates to valve with high intensity handle, belongs to valve arrangement technical field.
Background technology
Valve is the control unit in fluid delivery system, has cut-off, regulation, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the function such as overflow pressure relief；Valve handle is a kind of control member of valve, and it is connected with valve element, to realize by human control
Valve event；Because valve opening and closing needs certain torque, to ensure valve handle intensity, usual handle body uses metal material
Material is made；But metal handle feel is bad, and there may be corrosion, influence to use.
Existing valve handle is generally arranged a plastic bushing in its manipulatable end, as the protective case at valve management end, changes
The feel of valve handle has been apt to it, has played a part of antirust, but the plastic pipe sleeve installation being arranged is insecure, is easily shifted over, very
To being slipped from manipulatable end, protective effect is lost.
The content of the invention
The technical problem to be solved in the present invention is, in view of the shortcomings of the prior art, proposing that a kind of intensity is high and service life is grown
Valve high intensity handle processing technology.
The present invention is to solve the technical scheme that above-mentioned technical problem proposes to be：A kind of processing work of valve high intensity handle
Skill, comprise the following steps：
(i) handle body is made, is comprised the following steps that：
A, dispensing, the mass percent composition of each component is in handle body：C：0.03-0.09%, Cr：0.13-0.19%, Si：

Eu：0.04-0.12%, Lu:0.01-0.08%, magnesia：0.29-0.33%, tungsten carbide:0.23-0.36%, surplus Fe；
B, melting raw material：Added raw materials into by the mass percent of predetermined each composition in smelting furnace, the temperature in smelting furnace is improved
To 1450 degrees Celsius to 1490 degrees Celsius, raw material is smelted to form alloy solution；
C, alloy solution obtained in the previous step is cooled down, uses the air-cooled cooldown rate with 11-13 DEG C/s by alloy solution
It is air-cooled to 800-850 degrees Celsius；
D, the alloy solution after previous step is cooled down carries out secondary smelting in smelting furnace, and the temperature in smelting furnace is brought up into 1350 takes the photograph
For family name's degree to 1380 degrees Celsius, alloy forms alloy solution by secondary smelting；
E, cast, secondary smelting formation alloy solution cast to the blank of obtained handle body；
F, the blank of handle body is machined；
G, the blank of the handle body after Vehicle Processing is subjected to sanding and polishing and handle body is made；
(ii) obtained handle body is heat-treated, concrete technology is：
A, heat：Handle body is heated to 850-875 DEG C, and is incubated 60-75min；
B, cool down：The air-cooled cooldown rate with 8-10 DEG C/s is used to accelerate handle body after being cooled to 400-450 DEG C, then air cooling
To room temperature；
C, once it is tempered：After handle body is heated into 700-750 DEG C of tempering 30-35min, warm 40s is treated, makes the temperature of handle body
Degree homogenization, accelerate to be cooled to room temperature afterwards with 15-18 DEG C/s cooldown rate；
D, double tempering：Room temperature is air-cooled to after handle body is heated into 660-680 DEG C of tempering 20-25min；
E, quench：Handle body quenching and preserving heat temperature is 600 DEG C ± 10 DEG C, soaking time 0.5-1.5h；Handle body quenches
Tank water cooling 10-15 minutes are quickly put into after the completion of heating, cooling bath water temperature is controlled at 25-35 DEG C；
(iii) in handle body electroplating of Zn-Ni alloy onto surface coating, zn-ni alloy depositses thickness is 80 ± 20 μm；
(iv) the method coating refractory coating on the surface of handle body by atomizing spraying, coating spraying thickness 1.5-2.5mm,
Second of spraying is carried out after solidifying 10-15 hours, coating spraying thickness 1.2-1.3mm, solidifies 10-15 hours, valve is made and uses
