The purpose that backflow preventer is set is to pollute the water quality of water inlet pipe in order to prevent pipe network water from flowing backwards.
During operation, when inflow during less than water yield, steady flow compensator cooperates vacuum suppresser to suppress the formation of negative pressure at the totally-enclosed state, and makes the pressure in the steady flow compensator be not less than a certain setting value all the time, thereby has protected the pressure of water inlet pipe to maintain all the time on the lowest service pressure; Simultaneously, the deposit water in the steady flow compensator will in time replenish, with regulating pondage; When inflow during greater than water yield, steady flow compensator and vacuum suppresser are under the situation of eliminating the instantaneous negative pressure that produces because of water pump water supply, compare by the setting pressure of water pump water inlet pipe pressure and outlet pressure sensor, when water inlet pipe pressure is lower than setting pressure, water pump carries out constant pressure water supply by setup pressure value, reaches the constant pressure on the outfall sewer, when water inlet pipe pressure during more than or equal to setup pressure value, the water pump autostop, and supply water by bypass pipe; When at low discharge or not during water, water pump will enter resting state automatically, and water pump is shut down, and then supplied water by low discharge pressurize pipe this moment, reaches energy-conservation better.
In running, when the fault because of water pump, outlet pressure sensor, switch board makes the pressure of outfall sewer out of control, and when exceeding the hyperpressure of setting; the overpressure protection apparatus action; the water pump termination of pumping is not damaged with protection pipe network and water appliance, guarantees safety.
The beneficial effects of the utility model are, steady flow compensator and vacuum suppresser are set have been realized directly being connected in series water supply with water inlet pipe, and water inlet pipe do not produced negative pressure, polluted water not, can make full use of original pressure of water inlet pipe, and be provided with low discharge or dry shutdown dormancy, and avoid the power consumption operation of water pump in poor efficiency, make energy-conservation the biglyyest; Simultaneously, cancelled pond, water tank, can save and take up an area of and investment, and convenient for installation and maintenance, and operating cost is low.
