Principle of work of the present utility model is:
When the water level in glass tube water level gauge changes up and down, the distributed capacitance near measuring junction can change, and water level switch K1, K2, K3, K4 are by measuring the change of electric capacity, the change of sensed water level.The water level switch of diverse location represents different water levels, and water level switch K1 represents surcharge water level, water level switch K2 represents full water water level, water level switch K3 represents moisturizing water level, water level switch K4 represents ultra low water level.The signal of each water level switch is summarized in signal and gathers control panel, by elements such as pilot relays, and controlling water level status indicator lamp, hummer work.
Observing and controlling process is as follows: water level switch K1 (superelevation), water level switch K2 (full water) use normally opened relay J1, J2, when water level namely not detected, water level switch K1, K2 disconnect, corresponding relay J 1, J2 power-off not adhesive, light emitting diode D1, D4 do not work.Water level switch K3 (moisturizing), water level switch K4 (ultralow) use normally closed switch, when water level namely not detected, switch closes, when water level being detected, switch disconnects, and corresponding relay J 3, J4 power-off not adhesive, light emitting diode D6, D8 do not work yet.During ordinary water level, water level is between water level switch K2 (full water) and water level switch K3 (moisturizing), when water level decreasing to water level switch K3 (moisturizing) below time, water level switch K3 closes, relay J 3 adhesive, light emitting diode D6 lights, represent the low position to needing moisturizing of water level, now, the normally opened contact J3-NO2 of relay J 3 closes, relay J 6 adhesive, normally opened contact J6-NO closed (can start water pump by controlling A.C. contactor), light emitting diode D11 lights simultaneously, represents that water pump carries out moisturizing.If due to certain because of, water level continues to drop to water level switch K4 (ultralow) position, water level switch K4 close, light emitting diode D8 lights, represent water level ultralow, by diode D10 drive buzzer warning.Meanwhile, relay J 4 adhesive, its exportable teletransmission in normally-open normally-close contact.When water level rises to more than water level switch K3 (moisturizing), water level switch K3 disconnects, and relay J 3 power-off discharges, light emitting diode D6 goes out, due to another normally opened contact JO-N01 self-locking of relay J 6, therefore relay J 6 continues adhesive, and water pump works on.When water level rises to water level switch K2 (full water), water level switch K2 closes, and light emitting diode D4 lights, relay J 2 adhesive, normally closed contact J2-NC2 disconnects, and relay J 6 power-off discharges, light emitting diode D11 goes out, and normally opened contact recovers normally open, and water pump quits work.If for a certain reason, water level continues to rise to water level switch K1 (superelevation) position, and water level switch K1 closes, and light emitting diode D1 lights, and represents water level superelevation, drives buzzer warning by diode D3.Meanwhile, relay J 1 adhesive, its exportable teletransmission in normally-open normally-close contact.
In addition, signal gathers relay J 1, J2, J3, J4, J6 on control panel and is dpdt relay, and except internal control, all have one group of normally-open normally-close contact to export, teletransmission sends water level signal to outside, controls external alert device, small pump etc.; Can be used as the detection part of boiler operatiopn secure data terminal, be convenient to water position status information to be undertaken recording by external detection system or external control system, forward, analyzed judgement, inform by short message etc.
