ASHRAE CHAPTER 46 صفحه 11
SAFETY DEVICES
The terms safety valve, relief valve, and safety relief valve are
sometimes used interchangeably, and although the devices generally
provide a similar function (safety), they have important differences
in their modes of operation and application in HVAC systems (Jordan
1998).
Safety valves open rapidly (pop-action). T
hey are used for gases
and vapors (e.g., compressed air and steam).
Relief valves open or close gradually in proportion to excessive
pressure. They are used for liquids (e.g., unheated water).
Safety relief valves perform a dual function: they open rapidly
(pop-action) for gases and vapors and gradually for liquids. Typical
HVAC application is for heating water.
