Description

Fully-automatic water supply system

The invention belongs to the water supply system technical field.

Present urban water use is generally nervous, and tap water pressure is lower, so highrise building all must add a cover water supply facilities, to guarantee normal water supply.Existing water-supply technology mainly contains jumbo high level cistern formula and two kinds of the high-pressure bottle vapour-pressure types that is located at ground.Adopt jumbo high level cistern, as be located at roof, not only increased the building load and, but also increased the cost of engineering the etch of roof; Build water tower as other and then both took up an area of, cost is higher.And adopt the water supply facilities of the high-pressure bottle vapour-pressure type be located at ground, and then its cost is still higher, the control section complex structure, and maintenance inconvenience, and to the quality requirement height of high-pressure bottle, so be not suitable for civilian very much.In addition, above-mentioned two kinds of water supply modes all have water based on reservoir, the problem that the not enough water pump of the water yield of having ignored reservoir draws water and the reservoir inflow produces during less than water yield.

The objective of the invention is the weak point at above-mentioned two kinds of water supply modes, provide a kind of with low cost to people, make, install and use all very easy fully-automatic water supply system, it is specially adapted to the civil high-rise buildings feedwater.

Major technique feature of the present invention be with a pressure switch and steady flushing small water case and water level controller thereof by automatic control circuit to the startup of pump motor with stop to control automatically, thereby guarantee the daily normal water supply of highrise building.

Compare with two kinds of above-mentioned basic water supply modes, the invention has the advantages that: not only floor space is little, does not need jumbo high level cistern, water tower or high-pressure bottle and charger thereof; And with low cost, install, easy to use, be particularly useful for not having originally the highrise building of high level cistern, its refitting engineer is also very easy.Automatic control section among the present invention can also be moved on the water facilities of existing high level cistern, and it is carried out Automatic Control.Automatic control function of the present invention is more complete, and accuracy is higher, and part replacement is convenient.Need not special messenger's keeping and maintenance.Be very suitable for the feedwater of civil high-rise buildings.

Structure principle chart of the present invention such as accompanying drawing (one) have one way valve 3 between water pump 1 and reservoir 2 delivery ports; Between one way valve and pond reservoir delivery port, pressure switch 4 is arranged; Into water limit switches 5 is arranged on the reservoir; The delivery port of water pump is directly received on the water pipe 6; Water halter 12 is arranged on the water pipe; Water pipe top connects the very little steady flushing small water case 7 of relative reservoir volume; Steady flushing small water case has dust cap 13 on it; The water level controller 8 that directly extends water tank bottom is housed in it.

Figure (two) is the structure chart of water level controller 8.

Figure (three) is an automatically controlled circuit diagram.

Now just be described with reference to the accompanying drawings its major technique feature and operating principle thereof:

Reservoir 2 is by 5 water inlets of water inlet limit switches.When the level pressure in the reservoir was lower than certain value, because of pressure switch K4 disconnects, water pump quit work, thereby when having prevented because of the few inflow of reservoir moisture storage capacity again less than the water pump pump-out, made the interrupted suction of water pump cause starting frequent or suck air.The pressure switch K4 closed type that is stressed.It is a closure of utilizing the pressure control switch contact of water level, can adopt pressure switch or electro connecting pressure gauge, the controlling value of its level pressure generally should be decided on the water yield of reservoir and the pump-out of water pump, cause and few can also keep horizontal plane to be higher than delivery port after wanting to guarantee enough to fill with steady flushing small water case, in order to avoid suction air, water pump 1 is directly intake to steady flushing small water case 7 with water pipe 6, and this both can conveniently install, and can directly supply water to the water halter when pump working again.Steady flushing small water case 7 is the very little containers of the relative reservoir of capacity, its effect is for fear of the Fraquent start because of water halter frequent open and close causing water pump, simultaneously, press the duty of the height control of pump of water level again by water level controller 8 wherein, to guarantee normal feedwater.The volume of the steady flushing small water case of cause is very little.Its capacity at least can be littler more than 10 times than jumbo high level cistern.Close or less than high-pressure bottle once the feedwater capacity, so can need not consider of the influence of its installation site to building, and the number of starts of water pump is not a lot, approximate the number of starts of high-pressure bottle vapour-pressure type water pump and compare with the number of starts of the water pump of big capacity high level cistern, then be inversely proportional to its Capacity Ratio: establish 0.2 ton of each household average water every day, 6 tons of other waters every day of 30 families, other establishes only 0.2 ton of the capacity of steady flushing small water case, then the average number of starts only 2 times per hour of water pump.Termination water pipe 6 under the steady flushing small water case, there is a water level controller 8 that directly extends water tank bottom its inside, the effect of water level controller is the height by water level and hangs down the starting of control of pump and stop, its form has multiple, but its function is when water level is gone up in water level arrival, disconnecting circuit, when water level was reduced to down water level, circuit was connected.The present invention has provided the water level controller 8 of a kind of structure shown in figure (two); It is with pipe 15, floating ring 11 compositions that can keep afloat and slide up and down of a carry magnet 14 of overcoat with water level, and pipe 15 should be can not leak, and can not be magnetized.Two switch tongue tubes of the upper and lower water level of control are housed in the pipe, last water level switch K10 is a closed type, the operating principle that following water level switch K9 is the controller of open type is when the floating ring of carry magnet 14 slides up and down with water level, magnet adhesive or separate reed switch contact and reach and be switched on or switched off circuit and come the starting of control of pump and stop.When in the steady flushing small water case 7 when anhydrous, floating ring is parked in down water level switch K9 place, and magnet adhesive K9 connects control circuit, and water pump is started working.After water enters water tank, the floating ring come-up, K switch 9 disconnects again, this moment, circuit was connected and the continuation conducting by the self-holding contact of relay J 1, and when floating ring floated to water level switch K10 place with water level, magnet had disconnected normally closed contact K10, control circuit disconnects, electromagnetic relay J1J2 all disconnects, and the self-holding contact of J1 is return also, and water pump quits work.When floating ring was reduced to down water level switch K9 place heavily again with water level, circuit was switched on once more, carries out so repeatedly.Water level controller can be installed on the dust cap 13, or be fixed on the little water tank 7, botch routines in order to avoid as far as possible, normally closed switch K10 can connect with the tongue tube of two closed types, and normally closed switch K9 composes in parallel with two tongue tubes of often opening to be connected on the control circuit.
