Heating Basics – Gas Valve Systems

Most commonly, pressure relief valves employ a spring loaded "poppet" valve as a valve element. The poppet includes an elastomeric seal or, in some high pressure designs a thermoplastic seal, which is configured to make a seal on a valve seat. In operation, the spring and upstream pressure apply opposing forces on the valve.

Nov 15, 2019 · Gas Water Heater Thermocouple. The thermocouple is a sensor that tells the gas valve when to allow gas to flow to the burner. Gas hot water heater troubleshooting often involves the thermocouple. When they go bad the will not allow the gas valve to release any gas. No gas, no hot water.

How vacuum can form in a steam system - Heating Help

The set pressure of a relief device is the pressure at which the device operates. For spring-operated relief valves, small amounts of leakage start to occur at 92–95% of the set pressure. A relief device's overpressure is the pressure increase over its set pressure, usually expressed as …

Jun 24, 2014 · Instead of using a spring-loaded check valve between the boiler-feed pump and the boiler, use a motorized valve. Control the motorized valve with a pump controller on the boiler. When the boiler needs water, it will open the valve, which, in turn, will start the boiler-feed pump though its end switch.

Air Vents / Vacuum Relief Selection

Oct 22, 2011 · Like a water heater or room heater thermocouple, a boiler thermocouple's main function is to shut off the gas valve when the pilot goes out. If the thermocouple wasn't there, and the gas valve stayed open, unburnt gas would collect around the burner assembly and eventually waft into the room, creating a fire and explosion hazard.

Fundamentals of Pressure Relief Valves

Aug 23, 2018 · The current actuates a spring mechanism on the gas valve that keeps the valve open. if the current is too weak, the spring closes the valve and the pilot goes out. The thermoelectric effect that makes a thermocouple work is called the Seebeck effect, named after the German physicist who discovered it in 1821.

A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction.A thermocouple produces a temperature-dependent voltage as a result of Seebeck effect, and this voltage can be interpreted to measure temperature.Thermocouples are widely used as temperature sensors.. Commercial thermocouples are inexpensive, interchangeable, are supplied

Jan 10, 2014 · It is installed so that its ends are in the pilot light of the furnace. The thermocouple detects the heat from the pilot light, and should the pilot light go out accidentally, the thermocouple will automatically shut off the gas valve. This prevents unburned gas from flooding into the combustion chamber, where a small spark might cause an explosion.

Zurn Wilkins Backflow Preventers

These vent flow capabilities are available from the manufacturer. The key to sizing a vent for pressure or vacuum relief is to make sure that the vent (with set point) chosen will flow the required amount of vapors at a pressure less than the design pressure of the tank. This insures that the tank's design pressure or vacuum are never exceeded.

Sizing Pressure-Relief Devices - AIChE

The relief valve shown in Figure 6 includes a pitot tube to reduce pressure build-up. When the valve is opening, high gas velocity through the seat ring creates an area of relatively low pressure. Low pressure near the end of the pitot tube draws gas out of the volume above the relief valve diaphragm and creates a …

Thermocouple - Wikipedia

vacuum ceases, a spring force pushes on a lever and the valve operating pincloses against the orifice, thus shutting-off the fuel flow. Therefore, the vacuum fuelock filter has two primary functions: (1) it prevents dirty fuel from reaching the carburetor and (2) it shuts off the fuel flow automatically, regardless of the ignition being on or off.

with the thermocouple, the gas valve allows gas to flow to main burner until the call for heat is satisfied. • Intermittent pilot (also known as "spark to pilot") – Pilot is ignited by a spark generated by an ignition module and electrode. When enough heat is generated in the thermocouple, the gas valve allows gas …
