摘要：
A drain valve slide and drain valve facing seal an elbow drain hole in a dry barrel fire hydrant when the main valve is closed. A first wedge on the main valve assembly engages the elbow when the main valve is opened and biases the drain valve slide and drain valve facing toward the elbow drain hole, creating a positive seal.
