ADJUSTABLE DRAIN VALVE FOR DRY BARREL FIRE HYDRANT
First Claim
1. A drain valve to drain water from a dry barrel hydrant, the dry barrel hydrant including a barrel coupled to an upper end of an elbow having a hollow body, and a main valve assembly configured to seal against a seat located below a drain hole in the upper end of the elbow, the main valve assembly moving from an open position allowing water to flow from the elbow into the barrel to a closed position in which the main valve assembly seals against the seat, blocking water flow from the elbow into the barrel, the drain valve comprising:
- a drain valve body fixed to the main valve assembly, the drain valve body including a drain valve facing configured to align with the drain hole of the elbow as a result of the main valve assembly being in the open position, and to not align with the drain hole of the elbow as a result of the main valve assembly being in the closed position;
a drain hole sleeve positioned in the drain hole of the elbow, the drain hole sleeve being hollow.
