Abstract:
     The photoelectrical autocontrolling pressure apparatus for boiler is a kind of photoelectrical autocontrolling pressure switch making the autocontrol be performed during boiler running. However, existing products are not a photoelectrical autocontrol switch special for controlling the pressure of boiler, especially without overpressure safety mechanism. This apparatus provides a photoelectrical autocontrolling pressure technique for the control of pressure of boiler and has overpressure safety mechanism. It acts as ensuring safe production, protecting production and environment, and saving energy. The apparatus has following advantages: simple construction technology, easy manufacturing, cheap cost of manufacture and obvious economic benifit.
