Embodiment
Fig. 1 is the scaling method of the one loop of nuclear power station voltage-stablizer shower valve polarization aperture of an embodiment, applied to voltage stabilizing
Device, the scaling method include：
Step S200：Start on-off type heater.
Heater includes six groups, is respectively：RCP001RS, RCP002RS, RCP003RS, RCP004RS, RCP005RS and
RCP006RS.In this step, the on-off type heater of startup is RCP001RS and RCP002RS, and output power is 24KW,
And power invariability after being powered.In voltage-stablizer low pressure, the pressure controling signal of voltage-stablizer connects RCP001RS and RCP002RS.
RCP001RS can also be connected with RCP002RS by operator under specified criteria, make the water heating vaporization of voltage-stablizer cause in pressure
Rise.
Step S300：Shower valve is adjusted to the first aperture, voltage-stablizer pressure is dropped to when starting on-off type heater
Pressure simultaneously keeps stable.
When operator puts into on-off type heater, pressure rises in voltage-stablizer, and the pressure controling signal of voltage-stablizer is connected
Shower valve.By adjusting the spigot baffle of shower valve, shower valve is set to open an aperture (the first aperture), shower water enters voltage-stablizer
Make steam condensation, temperature declines, and pressure declines.Spray valve opening size corresponds to the uninterrupted of shower water, is sprayed by adjusting
Valve to the first aperture can balance pressure increase caused by on-off type heater, so that the pressure remained steady in voltage-stablizer.
Step S400：It is to make the output power of proportion expression heater to adjust shower valve to the second aperture, second aperture
Reach preset value and aperture that voltage-stablizer pressure still remains unchanged.
The state for maintaining step S300 for a period of time, controls the pressure in voltage-stablizer and stablizes, then further open spray
Drench valve.Voltage-stablizer pressure declines at this time, and the pressure controling signal of voltage-stablizer connects proportion expression heater, passes through proportion expression heater
Water temperature in voltage-stablizer is further heated to open to balance the further of spray valve opening.In this step, proportion expression heater it is defeated
Go out power adjustable section, the output power by adjusting proportion expression heater can compensate for voltage-stablizer radiation loss and shower valve and continuously spray
Super cooling effect caused by leaching, so that the pressure remained steady in voltage-stablizer.
Specifically, when the output power of proportion expression heater reaches preset value, stop adjusting shower valve.Wherein preset value
Refer to：Output power accounting is 50% or so.I.e. by slowly adjusting shower valve, until the output power of proportion expression heater reaches
50% or so of output power accounting, and the stabilization of voltage-stablizer pressure is maintained, the aperture corresponding to shower valve is second at this time
Aperture.Optionally, preset value is 45% to 55% output power accounting.

In the present embodiment, spray valve opening is manually adjusted.The manually mechanical shutter of adjustment spray valve, makes spray
Leaching valve opening has the first aperture gradually to be opened to the second aperture.In opening process, since spray valve opening increase causes to flow through
The spray water flow of shower valve becomes larger, so as to cause voltage-stablizer pressure to decline, voltage-stablizer pressure controling signal is connected proportion expression and added
Hot device, makes proportion expression heater be continuously increased output power, to maintain voltage-stablizer pressure stability.When the output of proportion expression heater
When power reaches output power accounting 50%, stop adjusting process manually, record spray valve opening (the second aperture) at this time.
Specifically, shower valve includes the first shower valve and the second shower valve, the first shower valve and second shower valve

(i.e. spray flow) and, it is necessary to maintain a preset time after changing the output of proportion expression heater, can just make voltage-stablizer pressure steady
Decide.Optionally, preset time is 30 minutes or so.
Further, as shown in fig. 6, obtaining the second aperture, after the step of shower valve polarization aperture, further include：
Step S700：Proportion expression heater is arranged to automatic adjustment state, and exits on-off type heater.
