VALVE TRIM, AND THERMOSTATIC CONTROL DEVICE FOR CONTROL OF MASS FLOW Russian patent published in 2013 - IPC G05D23/02 

FIELD: machine building.

SUBSTANCE: valve trim for thermostatic control device to control the mass flow includes shutoff part (14) located in the valve seat and brought into movement with trigger shaft (16), housing part (18), to which there directed at least in some sections is trigger shaft (16), and at least one energy accumulating element (29) that is installed in housing part (18) and acts in the first movement direction so that shutoff part (14) of the valve is installed in initial position (28) relative to housing part (18), and at least one thermal actuating link (41) from alloy with shape memory, which contacts both housing part (18), and shutoff part (14) of the valve. Thermal link (41) is installed with possibility of acting in the direction opposite to the first movement direction and causes interchangeable movement of shutoff part (14) of the valve, which depends on temperature, at least of one energy accumulating element (29) so that interchangeable force of thermal actuating link (41) is higher than interchangeable force at least of one energy accumulating element (29). Housing part (18), shutoff part (14), trigger shaft (16), energy accumulating element (29) installed in housing part (18) and thermal link (41) form a unified assembly and are made in the form of a plug-in cartridge.

EFFECT: creation of the valve trim and thermostatic control device to control the mass flow, owing to which adaptation to control of the heating system with heated floor at least in one room can be possible.
