Kind Code:
A1
Abstract:
A simplified valve (100) which can efficiently discharge hot water or cold water, which is safe because of being prevented from being tampered by an infant, and which is inexpensive because of having a simplified configuration.
The simplified valve (100) comprises a valve main body (10), a valve element (20), a lid body (30), a valve shaft (50), and a main lever (60). The simplified valve (100) also comprises a rotatable safety securing plate (40) having a second mark (40a) provided on the outer peripheral surface of the rotatable safety securing plate (40). Hot water or cold water can be discharged only when the main lever (60) is set to be operable by rotating the safety securing plate (40) to match the second mark (40a) with a first mark (10a) provided on the outer surface of the valve main body (10).
