PURPOSE: A supply control device of valley water for a small water supply is provided to accurately control the supply of valley water by preventing the malfunction of a ball valve. CONSTITUTION: A supply control device of valley water for a small water supply comprises a ball valve(10), an overflow pipe(20), a ball top device(30), a two-way gear, a pair of ratchets, a float bar(60), and ratchet release units. The ball valve is connected to the front end of a water pipe(2) connected to the inside a water tank and has a valve shaft. The valve shaft penetrates through a base plate(3). The overflow pipe is installed in the water pipe. The ball top device has a floating body(32). The floating body is installed in the bottom end of a valve operation unit(31) integrally attached on the valve shaft. The two-way gear is integrally attached on the front surface of the valve operation unit. The ratchets are rotatably installed in both sides of the top base of the two-way valve and prevent the two-way valve from reversely rotating. The float bar has a float(62) rotated depending on a water level change. The ratchet release units are integrally attached on both sides of the float bar and release the setting of the ratchets. |
