VALVE ASSEMBLY Russian patent published in 2013 - IPC G05D23/275 F28F27/02 

FIELD: heating.

SUBSTANCE: valve assembly includes a valve that controls heat carrier flow rate in a heat exchange unit, which has primary circuit and secondary circuit, and a valve control device having a thermostatic element that is subject to influence of temperature in secondary circuit and that can be subject to a temperature and/or pressure variation device. A physical value obtained from valve (2) or heat exchange unit (22) has effect on the above device (14. 30) of temperature and/or pressure variation. Heat exchange unit is made in the form of water heater (22) having primary supply pipeline (25) and primary discharge pipeline (26) in primary circuit (23), as well as secondary supply pipeline (27) and secondary discharge pipeline (28) in secondary circuit (24). At that, water having increased temperature can be taken through secondary discharge pipeline (28). Temperature of primary supply pipeline (25) acts on device (14, 30) of temperature and/or pressure variation.

EFFECT: providing quick control of a valve at the appropriate control characteristic.
