ABSTRACT:
An auxiliary safety valve for interposition in a pressurized fluid system including a cylindrical valve body having threads for connecting the valve body to the outlet end of a pressurized container for communication therewith. The valve body has a main bore adapted to align with the outlet end of a pressurized container and an auxiliary bore formed at an acute angle to the main bore and joining with the main bore. A ball seat is formed substantially where the auxiliary bore joins the main bore, and a ball mounted in the auxiliary bore for movement therein and to said ball seat to close off the main bore when the pressure flow through the main bore exceeds a predetermined level of flow together with threads on the valve body for connecting the valve body to an outlet control valve for communication therewith.
The valve body also includes a conduit with a valve control therefor which bypasses the auxiliary valve for equalizing pressure within the container and at a point outwardly of the auxiliary valve.
