Abstract
The utility model relates to a microsize automatic device for water supply for the life, the production and the fire water supply, comprising a water tank 1, a pump electric machine D and a control box 5 providing with a control circuit. The utility model is in parallel connected with a water supply line. When the pressure of the tap water is lower, the pressure return difference generated by opening a water tap makes the pump electric machine run to supply the water by a pressure gauge with an electric contact communicating with the control circuit. The utility model is simple in structured, convenient in installation and use, small in occupation area and low in cost and is suitable to be used for residential houses buildings.
Description
The utility model relates to a kind of miniature automatic water supply device of be used for life, production and fire water supply, particularly residential houses building domestic water.
Before the utility model proposes, existing building generally adopts water tower to become high-level tank water, and existing problem is that floor space is big, cost height and water quality vulnerable to pollution.At present, a kind of diaphragm type automatic air pressure appears on the market
Water supply facilities, it is made up of parts such as barrier diaphragm-type pressurized water tank, water pump, automatic control cabinet, pipelines, though solved the more existing problems of water tower or water tank, but because of its barrier diaphragm-type pressurized water tank complex structure, difficulty of processing is big, control circuit is also complicated, thereby cost is still higher, is not suitable for promoting the use of at the residential houses building.
The purpose of this utility model is to avoid existing weak point in the above-mentioned prior art and proposes a kind of miniature automatic water supply device, and this apparatus structure is simple, installation, easy to use, and occupation of land face is little and cost is lower.
Technical solution of the present utility model is: a kind of miniature automatic water supply device, and it is made up of water tank, the pump motor of interior dress float valve and control cabinet that control circuit is housed, and water outlet of water tank inserts user's water pipeline by water pipe through pump motor, one way valve.
The control circuit of the utility model control cabinet comprises major loop and control loop.Major loop is in series by normally open contact and the pump motor D of fuse RD1, A.C. contactor CJ.Incorporate major loop into after the normally closed interlock of the toggle switch K1 of control loop, fuse RD2, water level switch SK, electro connecting pressure gauge lower limit contact YT1, relay J 2, the series connection of relay J 1 line bag; After electro connecting pressure gauge upper limit contact YT2 connects with relay J 2 line bags and at YT1 and J1 line bag two ends; After often the opening control contact and its line bag and relay J 1 normally open contact connected of A.C. contactor CJ also and at YT1 and J1 line bag two ends.Electro connecting pressure gauge is connected with the one way valve outlet by pipe, and water tank is connected with water level switch SK by pipe.
Automatic water supply device of the present utility model and user's water supply pipe also connect, and its input voltage is 220 volts.When pump motor D delivery port pressure is lower than the electro connecting pressure gauge lower limit, make J1 line Bao Dedian by YT1, the adhesive of J1 normally open contact makes the adhesive of A.C. contactor CJ normally open contact connect pump motor D circuit, pump motor running, water supply installation work.Along with pressure of supply water rises gradually, YT1 disconnects, and this moment, pump motor still can remain in operation owing to the CJ self-locking.When pressure of supply water surpassed the electro connecting pressure gauge higher limit, YT2 connected that J2 is got is electric, and the J2 normally closed interlock disconnects, J1 line bag dead electricity and disconnect CJ, and pump motor is out of service.Afterwards, along with user's water, pressure of supply water descends gradually, and when being lower than the low pressure limit value, pump motor could start and repeat above-mentioned circulation.
From the above, when tap water pressure was higher, this device was not worked.And when tap water pressure was low, user's tap of fetching boiling water produced the pressure return difference and makes A.C. contactor line Bao Dedian by electro connecting pressure gauge, the water pump water supply start.After closing water tap, when pressure of supply water rises to certain value, make pump motor stop to supply water by electro connecting pressure gauge.Cistern water level is controlled by float valve.Thereby the utility model installation, easy to use, simple in structure, occupation of land face is little and cost is lower, is particularly suitable for the residential houses building and uses.In addition, because the water in the water tank is in flow regime often, water quality is good.The diet health that helps the resident.
Following accompanying drawing has been described an embodiment of the present utility model.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model control cabinet inner control wiring diagram.
Referring to Fig. 1, water tank of the present utility model 1 is welded by steel plate, at water tank water inlet place the float valve 2 that is used for control water level is housed, and its delivery port is communicated with user's water pipeline through pump motor D, one way valve 3 by water pipe.Control circuit (referring to Fig. 2) is housed in the control cabinet 5, and its major loop is in series by normally open contact and the pump motor D of fuse RD1, A.C. contactor CJ.Incorporate major loop into after the toggle switch K1 of its control loop, fuse RD2, vapour-pressure type water level switch SK, electro connecting pressure gauge lower limit contact YT1, relay J 2 normally closed interlocks, the series connection of relay J 1 line bag.As further special character, between SK and YT1, be in series with quartzy time switch clock SJ and hand switch K2 parallel with one another, so that supply water to the user according to user's needs setting-up time section.Electro connecting pressure gauge upper limit contact YT2 connects with relay J 2 line bags and all is connected in parallel on YT1 and J1 line bag two ends after often the opening control contact and line bag and relay J 1 normally open contact being connected of back and A.C. contactor CJ.Outlet is connected electro connecting pressure gauge with one way valve by rubber tube 4, and water tank is connected with water level switch SK by rubber tube.
The utility model control circuit also is connected to indicator lamp D1 and the D2 that represents power connection and machine operation respectively.
Miniature automatic water supply device of the present utility model is at input voltage 220V, maximum current 10A, and below the pump motor power 2.2KW, pump head h=32m, flow Q=3.5m
2/ h, supplying water highly reaches 25 meters.Electro connecting pressure gauge can be selected YT-603, and A.C. contactor can be selected CJ10-10, and relay can be selected JZX-2Z, and quartz clock can be selected the SDK-2 type.
