发明名称 Swiveling intake elbow for dry sectional gate valve
摘要 A dry sectional gate valve having a swiveling intake elbow and shot pin assembly for selectively locking the elbow into a fixed position. A shot pin extends from a pull-knob through the flange of the elbow into one of a plurality of spaced-apart detent slots or holes around the perimeter of the valve body. The elbow can be swiveled thereby allowing a connecting fire hose to be positioned to minimize kinks and avoid obstacles thereby bringing water freely into the valve. The shot pin can be used to selectively lock the elbow in a desired position facilitating connection and disconnection of mating fire hose couplings or the shot pin can be set to allow the elbow to rotate freely enabling the hose to reach its most relaxed position when charged.
