TEMPERED WATER MIXING SYSTEM

摘要

An improved tempered water mixing system comprises a thermostatically operated main mixing valve for blending cold and hot water supplies during normal system operation, a secondary temperature-limiting flow-control devic e in the form of a thermostatic valve, and a pressure-responsive flow control device in the form of a pressure regulating valve (also known as a pressure regulator), with the thermostatic valve and the pressure regulating valve being connecte d to function as fail-safe devices so as to provide an uninterrupted discharge outflow at a substantial flow rate in the event of a malfunction of the main mixing valve.
