ANTIFREEZE SPRAY BEAM

PURPOSE: An antifreezing spray rod is provided to discharge residual spray liquid remaining in a spray pipe by opening an exhaust valve and closing an index caulk, thereby preventing freezing in a spray pipe. CONSTITUTION: An antifreezing spray rod is provided to have an index caulk(4) which opens and closes flow path from a supply hose(H) to a spray pipe(2) in a base part. A discharge valve(5) is installed in the spray rod so that residual spray liquid can be discharged by passing through the discharge valve, when the index caulk is closed. The index caulk and the discharge valve consists of a three directions valve which selectively converts the connection of the spray pipe with regard to a drain(10), and the connection to the supply hose.
