Embodiment 3
That is the specific implementation of operation principle：
1st, the concrete operation method of dynamic constant pressure power control function：Discharge pressure setting value is input into control unit 3.Water outlet
The collection pressure signal of pressure probe 7 of mouth simultaneously feeds back to control unit 3, is judged by control unit 3.If the pressure of delivery port
More than discharge pressure setting value, then control unit 3 sends operational order to the pressure signals that collect of power probe 7, increase flap 1 with
The vertical plane area of medium, reduces aperture, so that increase resistance, so that the pressure letter that the pressure probe 7 of delivery port is collected
Number be equal to input discharge pressure setting value.If the pressure signal that the pressure probe 7 of delivery port is collected is less than discharge pressure
Setting value, then operate opposite.
2nd, the concrete operation method of dynamic constant flux control function：Pressure differential resetting value is input into control unit 3.
The pressure probe 7 of delivery port and the pressure probe 7 of water inlet gather pressure signal and feed back to control unit 3, by
Control unit 3 carries out subtraction and judgement.If the actual pressure differential that control unit 3 is calculated is more than pressure differential resetting value, control
Unit 3 sends operational order, increase flap 1 and the vertical plane area of medium, reduces aperture, so that increase load, so that control
The actual pressure differential that unit processed 3 is calculated is equal to pressure differential resetting value.If the actual pressure differential that control unit 3 is calculated is less than pressure differential resetting
Value, then operate opposite.
3rd, the concrete operation method of automatic energy tracing control function：Temperature difference setting value is input into control unit 3.
