Boiler Mountings - Dead Weight Safety Valve

DEAD WEIGHT SAFETY VALVE

Function:-

A valve is placed upon a valve seat that is fixed upon a long vertical pipe having a flange at the bottom for fixing at the top of the boiler. Suspended at the top of the valve is the weight carrier that carries cast iron rings. The total weight must be sufficient to keep the valve on its seat against the normal working pressure. When the steam pressure exceeds the normal limit, it lifts the valve with its weight & the excess steam escape through the pipe to the outside. This valve is used only with stationary type of boilers. It is the most elementary type of safety valve. The objection to dead weight safety valve is the heavy weight that has to be carried.
