THROTTLE Russian patent published in 2010 - IPC F22B37/74 F16K47/00 

FIELD: machine building.

SUBSTANCE: throttle, mainly, for installation into hydraulic line of heat exchanging pipe of steam generator consists of throttling element placed with tightness in flow section of heat exchanging pipe; case of throttle element has inlet and outlet channels. Also the throttling element has multitude of channels and is installed in a cavity between subs which are arranged at break of the heat exchanging pipe and tied between them with bushings. The input channels are made along axis of the throttle with offset from its axis, also change of direction of liquid flow to opposite is achieved by connecting outlets of the inlet channels to end surfaces of the throttle with grooves. The grooves are limited with straps rigidly tied with the throttle.

EFFECT: improved conditions of operation of bundle of heat exchanging pipes of steam generating NPI (nuclear power installation).
