CONTROL VALVE, DEVICE TO MEASURE AND CONTROL FLOW Russian patent published in 2008 - IPC F16K7/04 G05D7/00 

FIELD: mechanics; valves production.

SUBSTANCE: pack of inventions relates to valves production, in particular, to control valves incorporating a driving mechanism with a minor friction and is designed to control flowing media in various industrial branches, e.g. in semiconductor production, pharmacology and biotechnology. The control valve incorporates an elastomer flow pipe, plunger (124) with the first and second ends. a clamping element (502) coupled to plunger the first end and abuts with the flow pipe. Reference surface (128) is arranged, primarily, opposite to clamping element (502) so that the elastomer gets clamped between clamping element (502) and reference surface (128) to control the liquid medium along the flow pipe. First driving spring (511) is arranged between clamping element (502) and the first end of plunger (124). Second driving spring (510) abuts with the second end of plunger (124). The device to control and measure the flow is a control valve with body (101) and flow meter (112). This pack of inventions aims at increasing the accuracy of control of flowing media.

EFFECT: increasing the accuracy of control of flowing media.
