EMERGENCY SHOWER WITH IMPROVED VALVE ACTUATION

摘要

The emergency shower includes a discharge outlet pivotable between a first non-use position and a second deployed position about a rotary union, for dispensing water therefrom. A ball valve is positionable between a first flow restricting position and a second flow permitting position, when the discharge outlet pivots between the first non-use and second deployed positions. A linkage system actuates ball valve movement when the discharge outlet pivots, by way of a first link pivotally coupled relative to the discharge outlet and movable therewith and a second link pivotally coupled with the ball valve and responsive to movement of the first link, the second link positions the ball valve in the first flow restricting position when the discharge outlet is in the first non-use position and commensurately moves the ball valve to the second flow permitting position when the discharge outlet pivots to the second deployed position.

1. An emergency shower with improved valve actuation, comprising:
a shower head arm pivotable between a first non-use position and a second deployed position for dispensing water out therefrom; a rotary union coupled relative to the shower head arm to permit pivotable movement thereof between the first non-use position and the second deployed position; a ball valve positionable between a first flow restricting position when the shower head arm is in the first non-use position and a second flow permitting position when the shower head arm pivots about the rotary union to the second deployed position; and a linkage system having a first link pivotally coupled relative to the shower head arm and movable therewith between the first non-use position and the second deployed position and a second link pivotally coupled with the ball valve and responsive to movement of the first link with the shower head arm, the second link positioning the ball valve in the first flow restricting position when the shower head arm is in the first non-use position and commensurately moving of the ball valve to the second flow permitting position when the shower head arm is pivoted to the second deployed position.
