Solenoid valve to fill pressure release to constant pressure supply water.
Specific works situation is that after refrigeration unit unlatching, have certain pressure on cold-water return pipeline, this pressure value
Switch board is fed back to by first pressure sensor, when the setting value of switch board is less than the pressure that first pressure sensor is fed back to
When value, the first water pump is started by switch board and fills progress constant pressure supply water to water-storage pressure, until the hydraulic pressure pressure value in first pipe
After reaching setting value, the first water pump is stopped, during this period, if the water storage that constant pressure supply water fills is not enough to cold water constant pressure supply water
When, the pressure value that constant pressure supply water fills is fed back to by switch board by second pressure sensor, at this moment switch board can start tap water
Second solenoid valve on pipeline gives constant pressure supply water to fill and carries out moisturizing, ensures the pressure on cold-water return pipeline with this；Work as control
When the setting value of cabinet is more than the pressure value of first pressure sensor feedback, switch board will start the first solenoid valve by cold-water return
Water in pipeline is discharged in constant pressure supply water filling, after the hydraulic pressure pressure value in first pipe reaches setting value, closes the first electricity
Magnet valve, during this period, if the water storage that fills of constant pressure supply water is excessive, the pressure that is filled constant pressure supply water by second pressure sensor
Value feeds back to switch board, and at this moment switch board can start third solenoid valve, is filled to constant pressure supply water and carries out pressure release through blow-off line, until
After hydraulic pressure pressure value in first pipe reaches setting value, the first solenoid valve and third solenoid valve are closed；First is used when moisturizing
Water pump and the second water pump, the first water pump make feed pump, and the second water pump makees reserve pump, when feed pump damages, pass through switch board
Quickly start the second pump, to ensure effective use of the utility model.
