Whirlpool 4322452 manual Regulator Operation

REGULATOR OPERATION

The pressure of the gas coming into the pressure regulator pushes against a spring-loaded diaphragm, forcing it upward. The diaphragm spring puts pressure on the diaphragm. In order to control the flow rate, the diaphragm has a tapered plug suspended from it to restrict or increase the gas flow pressure (see Figure 2-3).

As the gas pressure against the diaphragm drops, the tension from the spring pushes the diaphragm downward, moving the tapered plug away from the valve seat, allowing more gas pressure to flow to the burners (see Figure 2-4). Additional gas may then flow into the regulator, pushing the diaphragm back up, thus restricting the flow of gas pressure into the passage way, and the cycle can repeat. In this way, the diaphragm and tapered plug maintain a constant gas pressure level to the burners.
