<4>Working Principle

When the equipment is put into movement, the water from the tap-water pipe-net flows into the flow stabilizing can. When the water supply capacity of the pipe-net can meet with the demand of use, the pressure of it is kept with the normal water supply range, the negative-pressure preventing module controlled electric valve is opened and the pump moves to carry out the pressure-overlapped water supply; While the said capacity can not meet with the demand, the pipe-net pressure is lower than that for normal water supply, the said module automatically adjusts the opening of the electric valve till its being closed, at this time water supply by the flow stabilizing can is automatically switched in. The vacuum eliminator on the said can is opened therewith, preventing a negative pressure from being produced inside of the can.
