Zusammenfassung: | Disclosed is a ball valve timer device capable of being easily mounted in an existing ball valve, capable of setting time, having a simple configuration, and formed to lock the ball valve accurately after set time. The ball valve timer device mounted in the ball valve has a latching ratchet and a counter ratchet formed into two joints between a rotary cam and a valve rotary shaft, wherein the counter ratchet is inserted into a concave counter insertion groove in the rotary cam, and the rotary cam has a rotary tolerance groove formed at the center thereof and is able to rotate at a certain angle, so the ball valve can be instantaneously locked after the set time passes. Therefore, the ball valve timer device is capable of being used after mounted in the existing ball valve easily, so a complicated ball valve device does is not additionally required. In addition, the ball valve timer device is capable of locking the ball valve accurately after the set time, thereby usefully using the ball valve timer device in order to shut off air or a fluid, which flows in a pipeline, after certain time passes. |
