Abstract RU 2240459 C2

FIELD: piping valves and fittings.

SUBSTANCE: invention is designed for use on main lines as devices cutting off and regulating delivery of working medium flow, especially when handling aggressive medium and at wide range of operating temperatures. Proposed cock has body with disk and spring shutoff devices. These shutoff devices are installed for synchronous operation under action of screw drive. Damper space and deflector killing hydraulic pulses and turbulence in moving flow are arranged on lower part of disk shutoff device. Cock has rotary cylindrical shutoff device with calibrated holes operated by separated drive to register or disconnect calibrated holes and moving flow further on.

EFFECT: improved reliability of cock by killing turbulence and detonation pulses in flow.
