VALVE FOR CONTROLLING WATER LEVEL

摘要

A valve for controlling a water level is provided to minimize the number of failure thereof and to extend lifespan thereof by reducing the number of operation thereof. A valve for controlling a water level includes a valve body(20), an opening ball(40), first and second stems(60), a lever(80), and a floating ball(90). The valve body includes a liquid inflow passage. The opening ball is installed in the valve body and includes a through hole(40b). The through hole controls flow of the liquid in the valve body. The first stem includes a key(60a). The key is inserted in a groove(40a) formed on the opening ball for rotating the opening ball. The second stem is installed on the opening ball and supports rotation of the opening ball. The lever is installed on each of the first and second stems for rotating the first and second stems. The floating ball is installed on an end of the lever and rotates up and down according to the water level.
