초록

A trip control system for use with, for example, turbines, includes a porting manifold that supports and provides fluid to two or more trip manifolds, each of which includes a bleed circuit having two or more bleed valves connected in parallel between a trip header line and a return or dump line to bleed the hydraulic fluid pressure from the trip header line to thereby cause a trip. The trip control system includes redundant trip manifolds operating in parallel, wherein each trip manifold is able to independently engage a trip of the turbine and each of ...

청구항

1. A method of operating a controlled device using a trip manifold to deliver control pressure from a system pressure source to an input of a controlled device, the method comprising: receiving a trip signal from a controller;executing a tripping action of the trip manifold in response to receiving the trip signal from the controller, the tripping action including:de-energizing an actuator valve of a first control valve system to couple a control input of a control valve of the first control valve system to a drain line, wherein the control valve closes ...
