Be provided with air bag in the tank body of normal pressure tank, the upper end of normal pressure tank is provided with the automatic air valve 43 be communicated with inside air bag, and the lower end of normal pressure tank is provided with the interface 44 be communicated with inside air bag, and the water entering normal pressure tank is stored in air bag; The tank body of normal pressure tank is provided with the air vent 45 that normal pressure tank inside is communicated with air; Manual drain valve 46 is provided with, normal pressure tank and frame partial installation in the bottom of described normal pressure tank.Normal pressure tank is by being provided with the pipeline communication water supplement port 42 of moisturizing motor operated valve 41; With normal pressure tank connected moisturizing pipeline on be also provided with electronic drain valve 49.
Control unit 70 is arranged on the top of frame, is provided with the control panel 74 of control unit in frame.Extract duct is provided with a pressure of return water sensor 71, and pressure of return water sensor setting is in the water inlet side of reducing valve; Be provided with negative-pressure cup low water level sensor 72 in the bottom of negative-pressure cup, be provided with the LOAD CELLS 73 of water level in monitoring tank in the bottom of normal pressure tank; Control unit receives the signal that pressure of return water sensor, LOAD CELLS and negative-pressure cup low water level sensor send, and control unit controls the operation of three way cock, moisturizing motor operated valve and pressure release electromagnetic valve, and control unit also controls startup and the stopping of small pump.
The operating process of level pressure, expansion pressure release:
Pressure of return water Sensor monitoring reclaimed water system pressure, when system pressure is increased to the setting pressure upper limit (being generally setting value+0.2bar), pressure release electromagnetic valve is opened by control unit, the water raised causing system pressure is stored in normal pressure tank, the volume expansion of tank body barrier film air bag, maintains system pressure constant.If water level superelevation in normal pressure tank in pressure leak process, can open the manual drain valve of bottom of normal pressure tank hand-manipulated, or controlled to open electronic drain valve by control unit, normal pressure tank starts the tank body water level safety value that sluices.
When system pressure drops to setting pressure lower limit (being generally setting value-0.2bar), control unit sends signal to small pump, and the water in normal pressure tank is mended to reclaimed water system by small pump, and when system pressure reaches control program setting value, water pump quits work.
When system pressure change is less (being usually less than ± 0.2bar), the expansion drum being arranged on small pump exit plays the effect of voltage stabilizing, maintains system pressure dynamic equilibrium.
The operating process of exhaust:
When reclaimed water system pressure stability, equipment starts exhaust within a period of time.Control unit sends exhaust signal to three way cock, three way cock is communicated with small pump and negative-pressure cup (pressure release electromagnetic valve is now in closed condition), the water of reclaimed water system is full of negative-pressure cup by extract duct, small pump startup optimization, and the water of negative-pressure cup is refilled system.Due to the effect of reducing valve, under the effect of small pump, form negative pressure in negative-pressure cup, reduce because the solubility with pressure of air in water reduces, the water supplemented carries out gas-water separation in negative-pressure cup.When negative-pressure cup water level reaches the sensed position of negative-pressure cup low water level sensor, small pump is out of service, and the water in system flows in negative-pressure cup.Due to the great variety of pressure, system water carries out gas-water separation in negative pressure.Water constantly flows in negative-pressure cup, is discharged after isolated gas is extruded by the liquid level risen gradually by the automatic air valve of negative-pressure cup upper end.This part unsaturated water with high absorption character is noted back system again, for reaching air water solubility equilibria, the gas in absorption system is again made it balance.This device repeats such circulation, and the free gas in water and dissolved gas are just excluded in this circulation.
The water entering normal pressure tank also first can be exhausted by reducing pressure in normal pressure tank, then just can by benefit in system pipeline.Normal pressure tank is made up of air bag, tank body and automatic air valve, and tank interior communicates with air.During use, water does not contact completely with inner tank wall, so stopped to get rusty and the secondary pollution of water quality.The recirculated water of high pressure enters in air bag and becomes normal pressure, the gas evolution in water, discharges from the automatic air valve being arranged on normal pressure tank upper end.
The operating process of moisturizing:
LOAD CELLS monitoring tank body water level conditions bottom normal pressure tank, and measured value is fed back to control unit, when normal pressure tank water level is lower than setting value, control unit sends signal and opens moisturizing motor operated valve, the water source of municipal water supply pipeline is by water supplement port to moisturizing in normal pressure tank, and the water filled in normal pressure tank is softened through water softener.
