The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Embodiment:

As shown in Figure 1, the New-type boiler control device that the present embodiment provides, comprise Steam Heating module 1 and flatiron heater 2, Steam Heating module 1 is connected on both ends of power successively by power switch 3 and fuse 4, flatiron heater 2 is connected on both ends of power by power switch 3, and flatiron heater 2 comprises the first temperature controller 5 of series connection successively, flatiron heating tube 6 and thermal cut-off 7, at flatiron heater 2 two ends, be parallel with electromagnetic valve 8 and the microswitch 9 of series connection successively, described Steam Heating module 1 comprises the engine pressure switch 12 of series connection successively, steam heating pipe 10 and the second temperature controller 11, described engine pressure switch 12 is often open-normally closed interlock contact, the normally-closed contact of engine pressure switch 12 is connected between fuse 4 and steam heating pipe 10, the normally opened contact of engine pressure switch 12 is connected in parallel on the two ends that engine pressure switch 12 normally-closed contacts are connected with steam heating pipe 10, at the second temperature controller 11 two ends, be parallel with pumping motor 13 and the 3rd temperature controller 14 of series connection successively.

Operation principle: during work, switch on power, switch 3 switches on power, now the normally-closed contact of engine pressure switch 12 is in normally closed (connection) state, normally opened contact is in often opening (disconnection) state, the branch road being now communicated with normally-closed contact is in conducting state, now steam heating pipe 10 is in heated condition, the second temperature controller 11 is worked, by the branch, short-circuit being composed in series by pumping motor 13 and the 3rd temperature controller 14 in parallel on the second temperature controller 11, now pumping motor 13 is not worked, when the second temperature controller 11 along with steam heating pipe 10 heat and temperature rise to set temperature time, the second temperature controller 11 disconnects, and in temperature constant state, now make the normally-closed contact of engine pressure switch 12 become disconnection by normally closed (connection), normally opened contact becomes on-state by often opening (disconnection), the branch road conducting that normally opened contact is connected, cause steam heating pipe 10 not worked, and electric current flows to pumping motor 13 by the branch road on normally opened contact, make 13 conductings of pumping motor, in running order (realizing pumping draws water), when the temperature of the 3rd temperature controller 14 of connecting with pumping motor 13 reaches the temperature of setting, the 3rd temperature controller 14 disconnects, pumping motor 13 quits work, thereby realize overtemperature protection and temperature control by two temperature controllers, and control in the lump that pumping is drawn water and pumping on the control action of pressure valve to the water yield in pot, thereby guarantee the normal work of whole system.The thermostatically controlled Temperature Setting of the second temperature controller 11 is 175 ° in the present embodiment, and the Temperature Setting of the overtemperature protection of the 3rd temperature controller 14 is 110 °, and this is not the restriction to innovation and creation, and just preferred plan is considered the most.
