Abstract
A high speed valve has a valve body having a flow passage therethrough, and a poppet disposed within the valve body. The poppet is movable between a first position in which the poppet blocks the flow passage and a second position, and the poppet has a piston connected to a stem at a proximal end of the stem. The valve also has a rotating lever release mechanism adjacent a distal end of the stem.
Claims16
A valve actuation mechanism for a high rate discharge valve, comprising:
- a lever member with a first end and a second end;
- a pivot pin attached to the first end of the lever member, the pivot pin having a pivot pin axis;
- and
- a compression spring that contacts the second end of the lever member, wherein the load of the compression spring is perpendicular to the pin axis;
- and
- wherein the mechanism is attached to a valve body of the valve having a flow passage therethrough;
- and wherein the valve further comprises:
- a poppet disposed within the valve body, the poppet movable between a first position in which the poppet blocks the flow passage and a second position, the poppet containing a piston connected to a stem at a proximal end of the stem;
- wherein the pivot pin axis is parallel to an axis of the stem.
