摘要
A manifold safety valve assembly is disclosed. The assembly includes a manifold having at least two outlets and a flow director valve disposed between the outlets to direct fluid pressure from an inlet to one or the other of the outlets. Safety valve mechanisms are mounted at each manifold outlet. Each safety valve comprises a body having a main valve fluid passage. A rupture disk normally blocks an upstream location of the valve fluid passage. A pressure relief mechanism normally blocks a relatively downstream portion of the main fluid passage. A secondary fluid passage leads from a main fluid passage at a point between the rupture disk and a pressure relief mechanism to a gauge port.
