DRAW-BAR LOAD SENSING MECHANISM Russian patent published in 2002 - IPC

FIELD: automatization of heat and power generating installations. SUBSTANCE: invention specifically refers to automatization of control processes in steam and hot-water boilers. Draw-bar load sensing mechanism has smoke-removing conduit, bimetal sensitive element, switching element and element setting mechanism in operational condition. Switching element comes in the form of microswitch and lever is employed as element setting mechanism in operational condition. Adjustment screw setting driving member in working position between operational and emergency positions of bar is put on free end of bimetal sensitive element. EFFECT: expanded functional potential of draw-bar load sensing mechanism thanks to widened range of operational currents and voltages, increased sensitivity and possibility of its adjustment. 1 cl, 1 dwg
