摘要: In the burner control valve construction disclosed herein, a modulating throttle valve is positioned by a diaphragm. One side of the diaphragm is exposed to the gas inlet pressure while the pressure on the other side of the diaphragm is controlled by varying the duty cycle at which gas is alternately admitted and vented from the space adjacent the diaphragm, the admitting and venting of gas being controlled by an electromagnet energized by a suitable squarewave signal of adjustable duty cycle.

摘要: In the hot water heating system disclosed herein, a sensing means such as a thermistor provides a first electrical control signal which represents deviation of outlet water temperature from preselected value and a flowmeter provides a pulsating electrical signal having a frequency which varies as a function of rate of flow through the heating system. An output signal is generated having a frequency equal to that of the pulsating signal and a squarewave pulse duration which varies as a function of the first control signal. Heater means are then energized by the output signal so as to provide a thermal input to the heating system which is substantially proportional to the product of water output temperature deviation and flow rate. This control minimizes output temperature fluctuations due to thermal inertia and heater lag.
