APPARATUS FOR STEPPING ROTARY-TYPE MULTIPLE VALVE WHERE MULTI-FLOW-PATH FORMING CERAMIC FIXING PLATE AND FLOW-PATH-SELECTION CERAMIC ROTARY PLATE ARE SEPARATELY CONTACTED

摘要

PURPOSE: To provide an apparatus for stepping rotary-type multiple valve, which is able to minimize rotational friction in the multiple valve by allowing water to be discharged when a flow-path-selection ceramic rotary plate corresponds to one flow path without a rubber o-ring. CONSTITUTION: A purified water outlet (53) from a water purification tank (52), an acidic water outlet (57) from an acidic water tank (55), a cold water outlet (59) from an alkaline water tank (56) through an alkaline cold water tank (58), and a hot water outlet (61) from the alkaline water tank through an alkaline hot water tank (60) are connected to a plurality of water inlets (2,2"') formed on a rear side of a rotary-type multiple valve (1). Multi-flow-path forming ceramic fixing plate (3) connected to the water inlets and a flow-path-selection ceramic rotation plate (5) are formed in the multiple valve to be inserted into a shaft (6) of the multiple valve. Only the flow-path-selection ceramic rotation plate is rotated with the shaft when an assembly lever (7) is assembled so that a flow path of selected water of the multi-flow-path forming ceramic fixing plate is opened and closed to discharge the selected water through water outlet (4). A stepping apparatus (8) that is formed in front of the multiple valve installs spring supports to be inclinedly protruded over a fixing plate to support a plate spring. A ball-mounted stepping plate is inserted into the shaft to rotate with the shaft. A housing cap is covered on the stepping plate to be fixed to a housing cap of a signal generation device. Many angle-division-type ring recesses are formed on the inner front side of the housing cap so that the ball is inserted between the angle-division-type ring recesses or detached therefrom when the assembly lever rotates.
