Abstract
The present invention relates to a kind of processing technology of the piston rod with china protective layer, comprise the following steps：(i) dispensing：(ii) melting；(iii) refine：(iv) high-pressure casting；(v) (iii) forge；(vi) Vehicle Processing；(vii) quench；(viii) ion processing；(ix) electroplate；(x) china protective layer is covered in the outer surface of the zn-ni alloy depositses of piston rod.Because liquid Metal Filling die cavity speed is high during due to high-pressure casting; fluidised form is unstable; therefore use general casting die; casting is also easy to produce stomata, it is impossible to be heat-treated, and the processing technology of the piston rod with china protective layer of the invention forges treatment by carrying out to piston rod; eliminate the stomata of casting; so that hair training can be heat-treated so that the piston rod physical property for finally giving is more preferably, more durable.
Description
Technical field
The present invention relates to a kind of processing technology of the piston rod with china protective layer, belong to valve actuator technology neck
Domain.
Background technology
Valve electric actuator, is called electric device for valve, abbreviation Q type Densos, is a kind of control valve and its similar sets
The standby driving equipment realized unlatching, close or adjust control；Be widely used in electric power, metallurgy, oil, chemical industry, food, papermaking,
The industries such as pharmacy, water factory and sewage disposal, it is adaptable to butterfly valve, ball valve, plug valve, etc. make the valves of 90 ° of revolutions and its similar set
It is standby；If plus support can be used as angle distance electric executor, being such as used for air door, baffle door, gas baffle door and its class
Like equipment.
Piston rod is one of strength member of part of revolving valves YE, and the good job of piston rod quality is for part
Steady operation and the service life tool of turning valve have a significant impact.
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 corrosion resistance
The good piston rod with china protective layer of energy.
The present invention is that the technical scheme for solving above-mentioned technical problem proposition is：A kind of piston rod with china protective layer
