The present invention is leak-proof function is improved simple water supply directed to a control device, in particular a valley water tube and the overflow tube individual with two ball valves disposed to operate opening and closing mutually opposed to a new concept of a technique for preventing the feed leaks when a number of valleys in relate to.
Simple water supply control apparatus disclosed in the prior art includes a valve float consideration is being configured to momentarily turn repeat the operation as over time turn the valve shaft, increases the ball valve clearance correctly can not meet the level of the water tank with a leak occurs , the wear of the components (see, sheet, etc.) is caused a problem that the durability is lowered deep.
The invention accommodates class to two water supply ball valve and ball valve for overflow each individual is installed on the water supply pipe and the overflow pipe branches into the two sides at the top of a valley pipes linked in accordance with the water level as a way to sweep away the problems while mutually opposed to open and close in accordance with the turning operation of the float and for the overflow float and the technology that allows for precise interrupting a flow path of the water supply pipe and an overflow pipe at the same time characterized by a steel wanted.
