Structure is identical as solenoid valve connection structure, and the present invention repeats no more.
It is a kind of application example of the invention with further reference to Fig. 4.Boiler 1 includes the water level switch 11 of sensed water level, water
Bit switch 11 and water replanishing device are electrically connected and control the on-off of solenoid valve.Boiler 1 further includes being electrically connected with water level switch 11
Manual moisturizing switch 12, pressure switch 13, heating unit 14 and buzzer 15, it is logical that pressure switch 13 controls heating unit 14
It is disconnected.Water level switch 11 divides low middle high three water position status, and when boiler is in low water level, buzzer 15 must establish beginning alarm by cable, close
Manual moisturizing switch 12 is closed, boiler 1 carries out moisturizing；When moisturizing reaches mid water levels, manual moisturizing switch 12 is disconnected, and is pressed simultaneously
Power switch 13 detects pressure value, and boiler 1 is heated in heating unit energization, enters water replanishing device automatic water supplement shape at this time
State.
Specifically, the other end is electrically connected with buzzer 15 as shown in figure 5,11 one end of water level switch connects with power supply, when
When in low water level, L4 and L5 of water level switch 11 are connected, and buzzer 15 obtains electric generation low-water alarm, and equipment enters standby
State.Contactor KM01 and intermittent duty relay 16 are electrically connected between water replanishing device and water level switch 11, contactor KM01 is
Normally closed contactor and the on-off for controlling intermittent duty relay 16, when being in mid water levels, M3 is connected with M4, contactor KM01
For power loss normally off, when being in high water level, H2 is connected with H4, contactor KM01 for electric opening state.Intermittent duty relay
The 16 primary conversions for carrying out signal of the movement of interval 90 seconds, the first solenoid valve 51 of water replanishing device and the 4th solenoid valve 431 pass through
Intermittent duty relay 16 controls electric simultaneously and power loss, and second solenoid valve 61 and third solenoid valve 411 are same by intermittent duty relay 16
Electricity and power loss is made in time control, it is preferred that the time relay is connected in the first solenoid valve 51 and second solenoid valve 61, so that first
Solenoid valve 51 and second solenoid valve 61 can be delayed by opening.11 other end of water level switch is also electrically connected with pressure switch 13,
Contactor KM02 is equipped between water level switch 11 and pressure switch 13, contactor KM02 controls the on-off of heating unit 14.Contact
Device KM02 is normally open contactor, and when being in low water level, contactor KM02 is power loss opening state, when being in middle high water level,
Contactor KM02 be electric closed state.Water level switch 11 is electrically connected with manual moisturizing switch 12 and is equipped with therebetween and contacts
Device KM03, contactor KM03 are normally closed contactor, and when being in low water level, contactor KM03 is power loss closed state, when being in
When mid water levels, contactor KM03 be electric opening state.
It is anhydrous state in boiler 1 when initial, when needing boiler 1 to work, is closed the main power switch K01 of boiler 1,
Water level switch 11 must be electric, and detects that L4 and L5 of water level switch 11 connect, with L4 and L5 for low water level state in boiler 1
The buzzer 15 that position communicates obtains electric sending low-water alarm, and boiler 1 enters standby mode.
When low water level, L1 and L4 conductings, KM03 is closed state, by manually pressing manual moisturizing switch 12, boiler 1
Interior carry out moisturizing.When water reaches the mid water levels of boiler 1, L4 and L5 disconnections of water level switch 11, buzzer power-off stops
Alarm, meanwhile, L1 and L4 disconnections, contactor KM03 obtain electric opening, and manual moisturizing switch 12 is automatically stopped work；Pressure switch
13 detect the hydraulic pressure in boiler 1 to be closed, and M4 and the M6 conducting of water level switch 11, contactor KM02 obtain electric actuation, heats
Unit 14 heats water.
Then boiler 1 enters automatic water supplement program, and the first solenoid valve 51 and the 4th solenoid valve 431 remain turned-off, third
Solenoid valve 411 obtains electric opening, and second solenoid valve 61 is opened after time relay KT02 is delayed five seconds, the steam energy in boiler 1
It is enough first to be entered in water pressure buffer 3 through third solenoid valve 411, the pressure in water pressure buffer 3 is improved, then water pressure buffer
Water in 3 enters in boiler 1 through second solenoid valve 61, realizes moisturizing.After 90 seconds, if the water in water pressure buffer 3 is not
Make rate of water make-up deficiency in boiler 1 enough, 16 generation movement of intermittent duty relay is so that second solenoid valve 61 and third solenoid valve 411
It simultaneously closes off, the 4th solenoid valve 431 obtains electric opening, and the high steam in water pressure buffer 3 is flowed into through the 4th solenoid valve 431 to be stored up
Release is realized in water tank 2, the first solenoid valve 51 is opened after time relay KT01 is delayed five seconds, and the water energy in water tank 2 is enough
It is flowed into water pressure buffer 3.The acting again for 90 seconds after last time acts of intermittent duty relay 16, simultaneously closes off the first electromagnetism
Valve 51 and the 4th solenoid valve 431, open second solenoid valve 61 and third solenoid valve 411, and the water in water pressure buffer 3 is mended again
Enter in boiler 1, repeat above-mentioned movement, until stopping moisturizing after mending to 1 high water level of boiler.
When the water in boiler 1 gradually uses up decline by high water level, and is reduced to mid water levels, contactor KM01 power loss,
First solenoid valve 51 and the 4th solenoid valve 431 remain turned-off, and third solenoid valve 411 obtains electric opening, prolong in time relay KT02
Second solenoid valve 61 is opened after Shi Wumiao, carries out moisturizing to boiler 1；After 90 seconds, if water in water pressure buffer 3 it is insufficient and
So that rate of water make-up is insufficient in boiler 1,16 generation movement of intermittent duty relay so that second solenoid valve 61 and third solenoid valve 411 simultaneously
It closes, the 4th solenoid valve 431 obtains electric opening, and the high steam in water pressure buffer 3 flows into water tank 2 through the 4th solenoid valve 431
Interior realization release, the first solenoid valve 51 is opened after time relay KT01 is delayed five seconds, carries out moisturizing to water pressure buffer 3.
When 1 water level of boiler reaches high water level, H2 and H4 conductings, contactor KM01 obtain electric opening, so that interval
Relay 16 disconnects, the first solenoid valve 51, second solenoid valve 61, third solenoid valve 411 and the equal power loss of the 4th solenoid valve 431
It is in close state, waits moisturizing circulation next time.It is fast when being caused 1 moisturizing speed of boiler not catch up with consumption by accidental cause
When spending, water level triggers safeguard protection when being reduced to low water level, i.e. pressure switch 13 is opened, and heating unit 14 stops heating, together
When buzzer 15 sound an alarm.
The beneficial effects of the present invention are: 1. boiler replenishing water devices of the present invention can replace small pump to carry out moisturizing, saving is set
Standby cost and operating cost；
2. boiler replenishing water device of the present invention is equipped with water pressure buffer and connects the first steam of water pressure buffer and boiler
Branch, the steam in boiler, which is able to enter in water pressure buffer, is pressurized water pressure buffer, so that in water pressure buffer
The enough boilers that more smoothly flows into of water energy；
3. boiler replenishing water device of the present invention is additionally provided with the second steam branch, water tank and water pressure buffer pass through the second steam
Branch communicates, and the steam in water pressure buffer can flow into water tank, facilitates water tank to moisturizing in water pressure buffer；
4. the steam in boiler enters water supply tank condensation after steam channel is by water pressure buffer, in the process, steam
Steam packing closes transmission, and quality of steam can be protected, while steam can recycle, avoid wasting；
