SHUTOFF AND PRESSURE REGULATING VALVE

摘要

Fuel is directed to the stages of an afterburner by metering flow to the stages with a single metering valve (14) and by controlling the flow to each stage by means of an integral shutoff and regulating valve (16). Each shutoff valve opens and closes the fuel flow to a stage as required. Each regulating valve, which is housed within a respective shutoff valve, regulates flow to each segment as a function of the pressure drop across the metering valve (14) so that a constant weight flow to the segment is achieved.
