VALVE FACILITY FOR CONNECTING HEAT EXCHANGER OF WATER INTAKE TO HEATING SYSTEM Russian patent published in 2010 - IPC G05D16/06 F24D10/00 F16K7/12 

FIELD: machine building.

SUBSTANCE: invention refers to valve facility and is designed to connect heat exchanger of water intake to heating system. The valve facility for connecting heat exchanger (1) of water intake to the heating system consists of valve (20) of the primary circuit regulating flow of liquid heat carrier in primary circuit (2) of the heat exchanger and of valve (40) of the secondary circuit actuating flow of process water in secondary circuit (3) under effect of pressure change. Valve (20) of the primary circuit is actuated with valve (40) of the secondary circuit. Valve (20) of the primary circuit is installed in first element (51) of the case. Valve (40) of the secondary circuit is installed in second element (52) of the case. Both elements (51, 52) are connected by third element (53) of the case, wherein there is installed actuating device (47). Valve (20) of the primary circuit is actuated with valve (40) of the secondary circuit by means of actuating device (47). Valve (29) is installed before valve (20) of the first circuit; the valve responses to change of pressure and is equipped with membrane (30). The membrane extends to a zone of contact between first element (51) of the case and third element (53) of the case.

EFFECT: increased reliability of operation and simplification of manufacture of valve facility.
