PRESSURE CONTROL FIXED VALUE ADJUSTING SYSTEM BASED ON TORCH OPERATING CONDITION

摘要

A pressure control fixed value adjusting system based on a torch operating condition, comprising a fuel supply line (10), a Venturi burner (30) and a control valve (20) connecting to the fuel supply line (10), the control valve (20) being disposed on the fuel supply line (10) to control the valve opening for the fuel supply line (10), the control valve having a pressure control fixed value. The pressure control fixed value adjusting system comprises a controller (40) connecting to a torch operating condition sensor (50), the torch operating condition sensor (50) detecting the operating condition of the torch and sending the detected result to the controller (40), the controller (40) automatically adjusting, according to the detected results, the pressure control fixed value of the control valve (20).
