The utility model has the advantages of light weight, flexibility, small occupation area and automatic controlling operation; the utility model can effectively exert the water storage function of the water tank on the top of the high building; the utility model which is matched with a 2.2 power water pump can satisfy water supply for 150 families in a high building under fourteen storeys.
Description
The utility model relates to high residential building tap water automatic water supply device.
City tap-water supply system hydraulic pressure is lower, is higher than four layers floor, and general water service is not gone up.Therefore, occurred the pressure water supply device on the market, but that its weak point is an expense is higher, complex structure, and need certain pressure reduction, when water system hydraulic pressure is big, could use.The high building that has is at roof water tank to be set, and when big, tap water is directly imported in the water tank by the hydraulic pressure of water low peak period (as midnight) water system, and when water used up in the water tank, tap water can't be imported water tank by day.The high building that has is provided with water tank, and directly with in the tap water suction water tank, this way is unallowed in " water supply regulations " with electric pump, and it can produce negative pressure in water system, the water phenomenon occurs robbing.
It is low that the utility model purpose just provides a kind of cost, can give high building water tank constant pressure water supply automatically, when water tank overflows, and the automatic water supply device that stopping automatically again supplies water guarantees the high building water.
The utility model purpose is to be implemented by following technical solution: the building water supply device comprises steel water tank, motor, centrifugal water pump, automatic control power switchbox, water inlet pipe, outlet pipe etc., be characterized in that city tap-water directly inserts water tank, be provided with float valve, spilling water bucket, overflow pipe in the water tank, centrifugal water pump and motor are connected with the water tank bottom, centrifugal water pump is connected with outlet pipe by gate valve, flap valve again, outlet pipe is connected with water-supply-pipe, and water-supply-pipe directly feeds the water tank of high building roof.The electric contact vacuum meter is set on the water tank, and when water system was cut off the water the water tank lack of water, the electric contact vacuum meter was an outgoing signal, and control circuit is cut off the electricity supply by auxiliary reclay, the water pump autostop.Snubber and electro connecting pressure gauge are installed on the outlet pipe; electro connecting pressure gauge is provided with upper and lower two limit values; when roof water tank water is full; the value of electro connecting pressure gauge is a higher limit; pressure meter is that outgoing signal is given control circuit; control circuit cuts off control power supply, water pump autostop by auxiliary reclay.When the roof water tank lack of water, the value of electro connecting pressure gauge is a lower limit, and pressure meter is that outgoing signal is given control circuit, and control circuit is connected control power supply, water pump Auto Power On by auxiliary reclay.Automatic control circuit is to increase by three auxiliary reclays and electro connecting pressure gauge, electric contact vacuum meter automatic control circuit in the general control circuit.
Water supply installation light and flexible of the present utility model, floor space is little (generally takes up an area of 1.5m
2～2m
2, large-scale 3m
2～4m
2), need not increase and build fixation means, reduced investment, convenient for installation and maintenance, full automatic operation.In addition, this water supply installation can be given full play to roof water tank retaining adjustment function, relaxes peak water contradiction, does not rob water with the peak period and strives electricity, and adapted 2.2kw power water pump can satisfy the following building 150 family waters in floor rooms 14.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model automatically controlled circuit diagram.
Water supply installation of the present utility model comprises steel water tank 1, motor 20, centrifugal water pump 18, water inlet pipe 3, outlet pipe 5 etc.Water inlet pipe 3 one ends link to each other with water-supply systems by gate valve 10, and the other end inserts in the water tank 1.There is peep hole 4 water tank 1 side, and float valve 2, spilling water bucket 12, overflow pipe 13 are established in its inside, and when water in the jar was full, float valve 2 come-ups stoped water inlet pipe 3 water inlets, and the water that overflows simultaneously flows out water tank 1 from spilling water bucket 12, overflow pipe 13.The bottom of water tank 1 links to each other with centrifugal water pump 18, motor 20 by gate valve 11, and centrifugal water pump 18 is connected with outlet pipe 5 by gate valve 16, flap valve 17 again, and outlet pipe 5 is connected with water-supply-pipe 6 through gate valve 7, and water-supply-pipe 6 directly feeds in the high building roof water tank.One snubber 19 and electro connecting pressure gauge 15 are installed on the outlet pipe 5, and pressure meter 15 demonstrates the pressure of water in the water pipe 5.Electric contact vacuum meter 14 is installed, the pressure that vacuum meter 14 shows in the water tank 1 on the water tank 1.Automatic control power switchbox 22 is connected with motor 20 and centrifugal water pump 18 by lead 21, controls opening, stopping of motor 20 and centrifugal water pump 18.Automatic control circuits in the automatic control power switchbox 22 are to increase by three auxiliary reclays and electro connecting pressure gauge, electric contact vacuum meter automatic control circuit in the general control circuit.When hydraulic pressure in the city tap-water supply system was big, tap water directly entered into roof water tank by water-supply-pipe 6 through flap valve 9, gate valve 8.When water in the roof water tank is full; the force value that electro connecting pressure gauge 15 on the outlet pipe 5 demonstrates through snubber 19 is the higher limit that electro connecting pressure gauge 15 is set; electro connecting pressure gauge 15 outgoing signals; at this moment, 1JY upper limit constant open contact closure in control circuit, the 2ZJ auxiliary reclay is started working; the constant close contact of 2ZJ auxiliary reclay disconnects; control circuit cuts off the control power supply, and centrifugal water pump 18 and motor 20 autostops stop pumping.During the roof water tank lack of water, the lower limit of the force value that electro connecting pressure gauge 15 demonstrates for setting, electro connecting pressure gauge 15 outgoing signals, at this moment, 1JY lower limit constant open contact closure in control circuit, the 1ZJ auxiliary reclay is started working, the constant open contact closure of 1ZJ auxiliary reclay, control circuit is connected power supply, centrifugal water pump 18 and motor 20 Auto Power Ons, through outlet pipe 5, water-supply-pipe 6 is pumped in the roof water tank centrifugal water pump 18 with the water in the water tank 1.When the water-supply systems lack of water or when cutting off the water; lack of water in the water tank 1; electric contact vacuum meter 14 on the water tank 1 demonstrates the lower limit of setting, i.e. outgoing signal, at this moment; in control circuit; 2JY lower limit constant open contact closure, the 3ZJ auxiliary reclay is started working, and 3ZJ auxiliary reclay constant close contact disconnects; control circuit cuts off control power supply, centrifugal water pump 18 and motor 20 autostops.
