Description of drawings

An embodiment below is provided, and the utility model is described in further detail.

Fig. 1 is the schematic diagram of embodiment;

Fig. 2 is the electrical schematic diagram of embodiment.

The specific embodiment

Referring to Fig. 1, water storing tank 1 is equipped with into water water level controller 2 by tip position, by a jar position, the end water outlet water level controller 3 is installed, water storing tank 1 bottom weep hole is equipped with out water solenoid valve 4, go out the water inlet that water solenoid valve 4 is connected to out water pump 5, the delivery port that goes out water pump 5 is equipped with outlet pipe 8, and outlet pipe 8 is equipped with pressure switch 7, outlet pipe 8 is also connected to pressure surge tank 6, and outlet pipe 8 ends are equipped with 4 outlet valves 9; The water inlet of water treatment machine 11 is connected to water source (as the municipal tap water pipe), and the outlet water pipe of water treatment machine 11 is connected to water storing tank 1 top after being serially connected with entering water electromagnetic valve 10.The water inlet water level controller 2 of present embodiment and water outlet water level controller 3 all adopt 2 spacing control modes, when water level increases from low to high and surpass the upper limit water level of its setting, its output control contact action (as switching to disjunction) from closure, when water level reduced from high to low and surpass the lower limit water level of its setting, output contact restored (as from the disjunction to the closure).Referring to Fig. 2, control contact (1WK-1) with water inlet water level controller (1WK) behind the coils from parallel connection of coils of entering water electromagnetic valve 10 (2F) and water treatment machine pump motor A.C. contactor (2C) is connected in series, be attempted by transformer (1B) secondary windings X, A two ends then, the main contact (2C-1) of water treatment machine pump motor A.C. contactor (2C) and (2C-2) be connected in series with water treatment machine pump motor (2D); When water level in the water storing tank 1 is lower than the lower limit water level of into water water level controller 2 (1WK) setting, control contact (1WK-1) is connected, entering water electromagnetic valve 10 (2F) must be established by cable logical, water treatment machine pump motor A.C. contactor (2C) gets electric adhesive, constant open contact (2C-1) and (2C-2) closure, the water treatment machine pump motor gets electric operation, to water storing tank 1 water filling, when rising to the upper limit water level that surpasses water inlet water level controller 2 (1WK) setting along with water level, control contact (1WK-1) disconnects, entering water electromagnetic valve 10 (2F) is closed, and water treatment machine pump motor (2D) stall stops to water storing tank 1 water filling.When water level in 1 jar of the water storing tank is higher than the upper limit water level that water outlet water level controller 3 (2WK) sets, the control contact (2WK-1) of water outlet water level controller 3 (2WK) is connected, at this moment go out pump motor exchange contactor (1C) and go out water solenoid valve 4 (1F) whether adhesive depends on whether the contact of pressure switch 7 (1P) is closed, in the present embodiment, pressure switch 7 (1P) is two spacing electric contact pressure gauges, its control contact (1P-1) disconnects when outlet pipe 8 internal pressures are higher than its higher limit that sets, when the pressure in the outlet pipe 8 was lower than its lower limit that sets, its control contact (1P-1) was connected.When opening outlet valve 9 water intakings, outlet pipe 8 internal pressures descend, and cause control contact (1P-1) closure, go out water solenoid valve 4 (1F) and must establish by cable logical.Go out pump motor A.C. contactor (1C) simultaneously and get electric adhesive, its constant open contact (1C-1) and (1C-2) closure, go out pump motor (1D) and get electric operation, add force feed water to outlet pipe 8, after having got water and closing all outlet valves 9, outlet pipe 8 internal pressures rise on overpressure switch 7 (1P) setting value in limited time, control contact (1P-1) disconnects, go out pump motor (1D) stall, go out water solenoid valve 4 (1F) and close, block the pressure in the outlet pipe 8.Because bypass is connected to Pneumatic pressure surge tank 6 on outlet pipe 8, make when just opening outlet valve 9 and the not saltus step suddenly of pressure of outlet pipe 8 when going out pump motor (1D) starting, thereby improved the stability of pressure of supply water and prevented out the frequent start-stop of pump motor (1D).

So the utility model owing to the water of water storing tank bottom that supplies water with water pump pressurization output, has made full use of the volume of water storing tank with fully using seat, and water storing tank needn't high-orderly be installed; Next has adopted automated manner to control out the work of water pump, exempted when opening the tap water intaking also needs the manual control switch to go out the operation of water pump in the past, and the hydraulic pressure of output is very stable, it has realized need not the automatic control of Switching Power Supply with regard to practicable long distance and voltage stabilizing water outlet, and it is a kind of constant pressure water supply installation that is adapted at factory and public situation use.
