How Does a Natural Gas Regulator Work?

DATE:2014-06-20 | comments: | posted by:admin

Functions of the Regulator

The natural gas regulator plays several roles in the safe operation and use of natural gas appliances. The regulator accepts signals from the thermostat on when to turn on and turn off heat manufacture and flow. It also monitors and controls the pressure of the natural gas running through the appliance in keeping with its design and manufacturer's specifications. It also has a safety feature that if no flame is produced, the regulator cuts off the flow of natural gas so that unburnt fuel does not come  into the home.

Parts of the Regulator

A natural gas regulators accepts incoming gas from a line that is under very high pressure. Through a set of internal valves, it lowers the pressure of the gas to the level that your specific appliance is designed to function at. A regulator has three main working parts: the loading mechanism, the sensor element and the control device. All three work in conjunction to reduce and control the level of pressure that the natural gas is traveling under.

How Regulators Are Set

The setting of any given regulator is controlled by the loading mechanism that is fixed during manufacture. An internal spring often plays this role. When the regulator handle is turned, the spring inside compresses. That pressure is transmitted to the sensor element, which then prompts the control element to regulate the outgoing pressure of the natural gas.
