The water level display controller is composed of a power supply circuit, a water level transducing detecting circuit, a water level indicating circuit, a control circuit, etc. When the inside of a water tank does not have water, the controller automatically open an electromagnetic valve to fill water, an indicator lamp displays the water level situation, the controller automatically closes the electromagnetic valve after water is filled, and water filling is stopped. When water level is not high and needs water filling or water is not needed to be filled, two push-button switches are respectively pressed, and water can be filled or water filling can be stopped. The utility model has the advantages of simple structure, visual display, convenient installation, convenient use, convenient maintenance, and low cost.
Description
The utility model relates to a kind of water level display control unit, and the cistern water level that is particularly suitable for solar water heater shows control.
After the solar water heater Application and Development, the various automatons of its cistern water level are invented in succession and are used, but have some defectives to some extent, have fairly simple and automaticity is not high, inconvenience is installed, safeguarded to have too complicated and make cost higher.
The purpose of this utility model provide a kind of simple in structure, installation, easy to maintenance, cost is low, practical water level display controller.
The purpose of this utility model realizes with following technical proposals: it is made up of power circuit, level sensor testing circuit, water level indicating circuit and control circuit etc.The level sensor circuit is sent water level signal into control circuit, and then control electromagnetic valve opens or close, and makes the water in the water tank use up back water filling automatically, stops water filling after filling with automatically.
The sensor that positive source and resistance R 01, R02, R03 form and R18, C2 also connect the base stage of T1, and the input of amplifier unit A1-A4 is anodal with 19 and connect the emitter of T1, composition level sensor testing circuit.
The output terminal of amplifier unit A1-A3 connect respectively R8 and L1, R9 and L2, R10 and L3, the output terminal of A4 and D5, R11, L4 are composed in series water level display circuit.
The base stage of the output terminal of A1 and D6, R15 series connection T3, the base stage of the collector of T3 and R16, R17 series connection T4; The output terminal of A4 connects the base stage of T2 through D5, R14, and the collector of T2 is in parallel with R16, R17 and C3.The collector of T4 with connect positive source after J1, D8 are in parallel, form control circuit after adding push switch K1, K2.
R12, L5 series connection back is in parallel with J1, forms working indicating.
Relay contact J1-1 with meet R17 after R13 connects, form the T4 conducting, the latching circuit after the J1 adhesive.
The two ends of push switch K1 meet R12 and R17 respectively, and the K2 two ends connect R17 and power cathode respectively.
The utility model circuit is simple, multiple functional, can start water filling automatically, can manual control add water in water utilizing process again, water can be filled with water tank and stop automatically, manual control stops water filling midway again, uses with convenient, through practical probation, have advantages such as installation and maintenance are convenient, economical and practical.
Contrast drawings and Examples below, the utility model is described in detail.
Fig. 1 water level display controller electrical schematic diagram
Fig. 2 is practical figure in solar water heater water tank
Symbolic representation is as follows in the accompanying drawing:
R01, R02, R03---detection resistance M---solenoid valve
K1, K2---push switch J1---relay
T1, T2, T3, T4---triode A1, A2, A3, A4---amplifier unit
L1, L, L3, L4---water level indicator light L5---water filling pilot lamp
Learn by Fig. 1, AC power is through step-down, D1-D4 rectification, C1 filtering provides dc supply, form the sensing detection circuit by R18, C2, R19, R01-R03 and T1, detect cistern water level, amplifier unit A1-A4 and R1-R5, T1, R19 etc. form four voltage comparator circuits, and its output directly drives pilot lamp L1-L4 and shows cistern water level; T2, T3 control T4 conducting or end makes relay J 1 adhesive or release, thus control electromagnetic valve open or close, make the water tank water filling or stop water filling.
In Fig. 2, water tank (1) water filling is gone into water inlet (2) by water supply line through solenoid valve (M), E, F among E, F among the figure, 4 water levels of G, H and Fig. 1, G, H are corresponding, and the resistance collection is put in the box (3) R01, R02, R03 are housed, and water tank metal support (4) connects positive source.
The course of work of the present utility model is such: (referring to Fig. 1, Fig. 2).
Energized, anhydrous in water tank this moment (1), A1-A4 exports electronegative potential, water level indicator light L1-L4 does not work, and T2, T3 end, and P, Q point is the high pressure position, the T4 conducting, the J1 adhesive, J1-2 connects, and solenoid valve (M) is opened, water tank (1) beginning water filling, L5 is bright for the water filling pilot lamp, and J1-1 connects, and the Q point keeps noble potential.
When water level rose to the E point, positive source connect support (4) through water tank water body and the conducting of E point, made A1 output noble potential, pilot lamp L1 is bright, the T3 conducting, and the P point is electronegative potential, connect power positive end owing to the Q point through R13, J1-1 this moment, and make the Q point keep noble potential, and water tank continues water filling.
When cistern water level is increased to F, G point successively, A2, A3 export noble potential successively, and pilot lamp L2, L3 light successively.
When water level continued to rise to the H point, A4 exported noble potential, and pilot lamp L4 is bright, the T2 conducting, and the Q point is electronegative potential, and T4 ends, and water filling pilot lamp L5 extinguishes, and J1 discharges, and J1-2 disconnects, and solenoid valve (M) cuts out, and water tank (1) stops water filling.(J1-1 also disconnects)
After the beginning water, water level is reduced to below the H point, and A4 exports electronegative potential, and T2 ends, and this moment, P point, Q point were electronegative potential still, thereby T4 still ends not water filling because J1-1 disconnects already, and T3 is conducting still.Be lower than the E point until cistern water level, A1 exports electronegative potential, and pilot lamp L1 extinguishes, and begins water filling after T3 ends again, repeats the above course of work.
When the not high need of water level add water after spending part water, press push switch K1, make the T4 conducting, J1 gets electric adhesive, J1-2 connects, and solenoid valve is opened and added water, stops to add water completely automatically until water: if do not need water is not filled it up with, press push switch K2, T4 is ended, can stop to add water.
