This Water Heater Gas Valve adjusting system comprises a controller, step motor, bidirectional quantitative gear pump, double spiral swing cylinder, Gas Water Heater Valve and other hydraulic components (hydraulic pipe, hydraulic lock).
Gas Water Heater Valve regulating the system principle of work as shown in figure 1. Stepper motor controller sends a signal receiving, driven bidirectional gear pump is (anti) turn oil, hydraulic oil through the pipeline, a positive driving swing cylinder screw (reverse) rotary screw, output and Gas Heater Valve stem is fixedly connected, so as to drive the rotary Gas Water Heater Valve stem, opening adjustment Gas Water Heater Valve, a pressure sensor at Gas Water Heater Valve outlet pipe, the controller through the analysis of pressure signal of artificial set and feedback signal, outputs a control signal to drive the motor action, finally realizes the fluid gas safety valves after the piping in the voltage stabilizing control.
