Fig. 2 is the left view of temperature control air door movement device among Fig. 1.
Fig. 3 is the enlarged drawing at I position among Fig. 2.
Fig. 4 to Fig. 6 is that the structure master of annexation between rotating shaft of the present invention, La Er and the tongue piece looks, overlooks and left view.
The specific embodiment
The example of concrete structure of the present invention and annexation can be referring to accompanying drawing.Fig. 1 is the embodiment that this device is applied to hot-water boiler, and the spring abutment 2 that wherein is built-in with memorial alloy spring 4 is fixed on the upper top position of boiler water jacket 3.Be fixed with trim ring 1 in the upper end of memorial alloy spring 4, backguy 8 upper ends are connected with trim ring 1, and the lower end passes spring abutment 2 bottoms, and fixing sheaths 6 stretch out water jacket 3 in the copper pipe 5 by being fixed in spring abutment 2 bottoms, are connected with the line ball nut 16 of the upper end of adjustment screw.
Fig. 2 is the structural representation of temperature control air door movement device, and the adjustment screw structure among the figure can be referring to Fig. 3.The upper end of adjustment screw is a line ball nut 16, and by these line ball nut 16 fixedly connected backguys 8, there is external screw thread the lower end of adjustment screw 9, and adjustment nut 18 spins on it.The movable bearing 17 that is equipped with on the adjustment screw above the adjusting nut 18 9, this bearing 17 is connected with drawing ear 20.Among Fig. 2, draw ear 19 to also have a back-moving spring 11 to be connected.These back-moving spring 11 other ends are fixed on the body of heater by hold-down screw 12.The air door 14 of boiler is fixed in the rotating shaft 22, and the tongue piece 19 at rotating shaft middle part is identical with air door 14 directions, is provided with to transfer wind knob, this accents wind knob to comprise to transfer conch female 15 and transfer conch to follow closely 13 on air door 14, and described accent conch is followed closely 13 and contacted with described tongue piece 19.
The structure of rotating shaft 22 in the temperature control air door movement device, tongue piece 19 and La Er 20 and annexation are referring to Fig. 4 to Fig. 6.Rotating shaft 22 is fixed on the body of heater by shaft seating 21, and air door is movably connected in the rotating shaft 22.Be provided with a tongue piece 19 at rotating shaft 22 middle parts, the left side of rotating shaft 22 is connected with a rectangular ear 20 that draws, and has the connecting hole 23 and the extension spring connecting hole 24 that is connected back-moving spring 11 that connects backguy 8 at the outside one end that draws ear 20.The accent wind knob of air door 14 is finished the task of damper by the action of tongue piece 19 with rotating shaft 22.
The realization of this device mainly is to realize by the memory function of memorial alloy spring change of shape to temperature, when rising on the memorial alloy spring memory temperature gradually, boiler temperature prescribes a time limit, the memorial alloy spring is stretched to extreme position gradually, drive the active force that backguy 5 overcomes return spring 11 by pushing circle 1, pulling rotating shaft 10 rotations, transfer the generation space between wind knob and the tongue piece 19, air door moves downward under the deadweight situation, intake reduces, furnace temperature reduces, memorial alloy spring 4 descends along with temperature and shrinks, pulling force reduces, return spring 11 active forces strengthen relatively, draw ear 20 rotating shafts 10 drive tongue pieces 19 to promote to transfer wind knobs 13 to open air door by effect and begin next circulation, by the temperature memory characteristic of memorial alloy spring 4, reach intelligence and adjust the door opening size, the output temperature that reaches boiler is constant, guarantees the control of intelligence ginseng, continues purpose of energy saving.
