REGULATOR WITH EFFICIENT GAS FLOW Russian patent published in 2012 - IPC G05D16/06 

FIELD: machine building.

SUBSTANCE: proposed device comprises valve body with inlet, outlet and throat arranged there between, drive secured to valve body to comprise valve plate and diaphragm articulated with valve plate. Said valve plate is arranged inside valve body to reciprocate between open position and closing position in response to pressure variation and valve body outlet taken up by diaphragm. It comprises also valve port arranged in valve body throat. Note here that said port comprises cylindrical component including valve seat and channel extending through valve port. Valve seat is tightly jointed with valve plate in closing position. Note here that said valve port features selected set of parameters including channel diameter and seat height corresponding to seat length along said channel. Said set is preselected from multiple sets of parameters, each including channel diameter and seat height. Note also that seat heights of said sets are in inverse relation with channel diameters.

EFFECT: high-efficiency gas flow at preset outlet pressure.
