Abstract
A safety screen assembly includes a shroud sleeve with an upstream end that defines a flow inlet. A spring seat is disposed downstream from the shroud sleeve and includes a flow outlet. A screen spool is operatively disposed between the flow inlet and the flow outlet and includes a tubular body with an inner passage, a screen disposed within the inner passage, and a plurality of bypass passages formed in the tubular body. The tubular body is in sliding engagement with the shroud sleeve in both a first position and a second position, the shroud sleeve closing the plurality of bypass passages from fluid flow when the tubular body is in the first position, and the plurality of bypass passages being open to fluid flow when the tubular body is in the second position. A spring biases the tubular body of the screen spool toward the first position.
