TURBINE EXPANDER CONTROL SYSTEM

摘要

turbine manufacture; turbine expander control systems. SUBSTANCE: control system of turbine expander installed on gas-distributing station between high- and low-pressure gas lines has gas heater, stop valve with actuator, and control element with actuator installed downstream of gas heater at its inlet to turbine expander; system also has bypass and shut-off valves with actuators installed in parallel with turbine expander. Inlet pipe connection of shut-off valve which opens in step with stop valve closure and vice versa is joined to high-pressure gas line upstream gas heater. EFFECT: enhanced reliability of supplying users with of desired parameters. 1 dwg
