In figure: the large storage tank of 1-, the little storage tank of 2-, 3-float valve, 4-blower pump for pipeline, 5-water pipe, 6-flap valve, 7-hydraulic pressure switch, 8-tap water pipe network, 9-electromagnetic valve, 10-water level switch, 11-timer switch.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed specific description.
The structure of the uninterrupted water supply installation that is used for water treatment machine that the utility model provides as shown in Figure 1, large storage tank 1 and little storage tank 2 all are communicated with tap water pipe network 8 by inlet pipeline, be provided with float valve 3 in described large storage tank 1, the bottom of little storage tank 2 is provided with the feed water inlet that is connected with water treatment machine, is provided with successively hydraulic pressure switch 7 and flap valve 6 on the pipeline between tap water pipe network 8 and little storage tank 2.
Be provided with water pipe 5 between large storage tank 1 and little storage tank 2, pipe pressurizing valve 4 is positioned on water pipe 5, one end of described water pipe 5 is communicated with the bottom delivery port of large storage tank 2, the other end of water pipe 5 is communicated with the inlet pipeline of little storage tank 2, and the tie point between two pipelines is between the water inlet at the top of flap valve 6 and little storage tank 2.
The circuit diagram of control circuit as shown in Figure 2, the external civilian electricity of control circuit, water level switch 10 is series in control circuit with blower pump for pipeline 4, and blower pump for pipeline 4 brings into operation when hydraulic pressure switch 7 is connected, and also is parallel with timer switch 11 on described hydraulic pressure switch 7.Be provided with water level switch 10 in described little storage tank 2, the inlet channel of little storage tank 2 is provided with electromagnetic valve 9, and described water level switch 10 and electromagnetic valve 9 are series in control circuit, and electromagnetic valve 9 cuts out when water level switch 10 disconnects.
The operating principle of the uninterrupted water supply installation that is used for water treatment machine that the utility model provides is as follows: be in parallel at control circuit hydraulic pressure switch and timer switch, when connecting arbitrarily a switch or two switches between the two and all connecting, blower pump for pipeline all can move, water in large storage tank is delivered in little storage tank, the flap valve that pipeline is provided with can prevent the current direction other places in large storage tank, thereby guarantees that the water in large storage tank is delivered in little storage tank.Therefore, too small when the hydraulic pressure of tap water pipe network or when cutting off the water, hydraulic pressure switch can be connected, and the water in large storage tank is delivered in little storage tank; On timer switch, the opening time section can be set, some that is arranged on every day is to some turn on-switch, when being in this period, regardless of water pressure conditions, timer switch all can be connected, thereby the water in large storage tank is delivered in little storage tank, can degenerate because of long-term the placement to guarantee the water in large storage tank.When the hydraulic pressure of tap water pipe network is normal, and when timer switch was outside set period, tap water flowed directly into little storage tank according to normal pipeline.Little storage tank inside is provided with water level switch, when the water in little storage tank is filled, and the water level switch automatic disconnection, this moment, the electromagnetic valve sealing, stopped supplying water in little storage tank.
