1. A discharge valve for mounting on a fire truck or the like for controlling the flow of water from a fire pump to a fire hose comprising:
- a valve body of a one-piece construction having a portion having an inlet waterway for the delivery of water from the discharge of the fire pump,means forming an outlet from said valve body,said valve body defining a valve chamber at the downstream end of said inlet waterway,a valve member rotatable within said valve chamber to control the flow of water through said valve body from said inlet waterway to said outlet,said discharge valve being mounted so that the water flows from said outlet along a horizontal axis,and a valve cover of a one-piece construction mounted in a fixed position on said valve body and having a portion forming a discharge passage for the flow of water from said outlet to a fire hose connected to said valve cover,said discharge forming portion being provided with means for connecting the end thereof to a fire hose,said discharge forming portion of said valve cover having its downstream end extending downwardly at a fixed predetermined angle from said horizontal axis to direct water flowing along said horizontal axis from said outlet downwardly at said fixed predetermined angle into a fire hose connected on the end thereof and extending therefrom to lay on the ground,said inlet waterway, said outlet, said valve chamber, and said discharge passage being of a substantial size to permit the flow of a volume of water to the fire hose sufficient for typical fire extinguishing purposes,said valve cover having an integral drain valve portion forming an inlet passage communicating with said discharge passage and an outlet passage adapted to be connected to drain valve piping,and including a drain valve member movable to open and close flow between said inlet and outlet passages of said drain valve,said drain valve member having an operating member adapted to be manually operated from the exterior of said valve cover between open and closed positions independently of the flow controlling position of said first-mentioned valve member.
