How a Natural Gas Regulator Works?
The regulator has an inlet and outlet. There is a valve at the inlet typically called a seat valve or similar. This seat is linked to a diaphragm. This diaphragm separates the upper and lower halves of the regulator body and also serves as the gasket for the two halves. On top of the diaphragm is a spring, below is the inlet seat. When no appliances are in use the lower section fills with gas, pushes the diaphragm up which seats the inlet valve and stops gas flow into the regulator. When an appliance is turned on, the gas flows out of the regulator and down the pipe to the appliance. When this happens the diaphragm lowers, opens the seat valve and gas once again flows. The seat valve has an orifice to reduce the speed at which the upstream gas enters the regulator, and the diaphragm spring determines how much pressure it takes to close the seat.
