Abstract
PURPOSE: To permit automatic drainage by arranging a drain cock at a water stop cock part and permit interconnection so that the drain cock is closed when the water stop cock is opened, and the drain cock is opened when the water stop cock is closed.
CONSTITUTION: In a water passage which leads from the water feeding port 2 of a water stop cock 1 to a water discharge port 3, a guide 8 having water passing holes 9 and 10 is arranged slidably and pressed onto the water stopping part 15 formed on the inner wall of the water passage by a spring 14 pressed by a blind cover 16. Onto said guide 8, a packing 13 having a water passing hole 12 which coincides with the water passing hole 9 is mounted, and the end part of an operating shaft 5 slidable in the axial direction opposes to the water passing hole 12. The water passing hole 10 described above is formed at the position opposed to the water feeding port 2, and a drain hole 19 is formed at the position where opening and closing are performed by the end part of the guide 8, and a drain cock 20 is arranged.
