CHANGE-OVER VALVE WITH AIR VENT VALVE
Document Type and Number:
Japanese Patent JPS56156565
Kind Code:
A
Abstract:
PURPOSE:To discover the abnormality of air vent rapidly by a mechanism wherein an air vent hole and a valve of an upper surface of a buoy are formed to a change- over valve, and air in the change-over valve is extracted to the outside. CONSTITUTION:When water is poured into a bath, a water level in a pipe 25 at the water suction side rises gradually, air in a change-over valve A is let escape to the outside in a cource of an air vent hole 5 and an air escaping groove 23, and the air vent hole 5 is clogged through the buoyancy of a buoy 6. When a valve 7 is not hermetically sealed due to fur, dust, etc., malfunction can easily be discovered because water passes through the air vent hole 5 and leaks from the surroundings of a handle 22 of an upper surface of a bathtub flange 18, and the abnormality of air vent can be discovered quickly.
