Turbin Emergency Shut-Off Valve(TSV)

home Products TRT Valves Turbin Emergency Shut-Off Valve(TSV)
Feature

A TRT (Top-pressure recovery Turbine) is installed in the downstream of gas-cleaning equipment for a blast furnace.
The function of this valve is to stop gas flow through the turbine in the event of turbine trip or emergency stop. Incorporated within the hydraulic cylinder, which drives the valve, is a spring back mechanism. By releasing the hydraulic oil pressure, TSV will repidly close within approx 0.5sec, in order to avoid the TRT over speed.

TRT (Top-pressure Recovery Turbine)설비는 제선공정에서 발생된 Blast Furnace Gas로 발전 터빈을 구동하는 설비이며 주요 배관에 설치되는 밸브입니다.
Turbine상의 문제가 발생시 긴급히 차단되는 밸브입니다. 유압식으로 동작이 이루어 지며 긴급 사항 발생시 유압이 해제되면서 0.5초 이내로 밸브가 clsose됩니다.
