THERMOSTATIC STEAM TRAP AND METHOD OF ITS OPERATION Russian patent published in 1997 - IPC

FIELD: pipe line fittings. SUBSTANCE: incoming flow of condensate is divided into two unequal flows; flow enters mixing chamber from opposite sides through valve member. Hydraulic force acting on control member is less than force of each separate flow. For realization of this method, use is made of device consisting of two valves fixed on common rod; their seats are arranged in mixing chamber for relative motion. EFFECT: enhanced efficiency. 4 cl, 1 dwg
