Field of the Invention The present invention relates to a timer device for a ball valve and a compressed air shutoff valve, and more particularly to a timer device and a compressed air shutoff valve for a ball valve for appropriately adjusting the amount of compressed air used in a ship manufacturing process.

Generally, a timer is used to appropriately control the amount of compressed air used in a ship manufacturing process. Conventional commercial timers can be divided into gas timers and water timers.

Conventionally, a compressed air shutoff valve equipped with a timer has been generally used with a relatively long time set by applying an electronic timer. However, there is a problem that the compressed air shutoff valve equipped with an electronic timer is not suitable for use in an explosion-proof area such as a painting factory.

For example, an air hose and a fall pipe air fan are usually used for paint drying and ventilation inside a block. Recently, an air fan has been developed and applied to reduce the amount of compressed air used. However, there has been a problem in that, after the night coating operation, the apparatus is turned on for a long time while air is used to dry the coating, and the compressed air is continuously supplied even after the completion of drying, resulting in ineffective coating drying due to waste of compressed air.

In order to solve such a conventional problem, in the present invention, it is possible to easily set the ball valve to be used and to set a time, and to provide a ball having a simple structure of the apparatus, A timer device for a valve is provided.

A rotary cam fixing pin 91 is protruded from the mechanical timer 90 toward the protruding direction of the timer shaft 21 and the rotary cam 30 is provided with a rotary cam fixing pin 91 And the counterclock ratchet 51 is configured to operate after a set time of the timer to release the latch ratchet 52 from the valve rotational axis 60. [
The timer device for a ball valve according to an embodiment of the present invention does not require a separate ball valve constituted by a spring spring and can be mounted on a conventional ball valve and includes a timer means 100, And a bracket 72 for coupling the timer unit 100 and the ball valve 70.

The timer means 100 includes a case 11 and an upper case 12, a ball valve knob 40 for opening and closing the ball valve 70, and a timer knob 20 for setting the time of the timer do.

[ Referring to FIG. 5 (B), the timer knob 20 is rotated in a clockwise direction to operate an internal component in which the time is set. When the rotation cam fixing pin 91 rotates in the clockwise direction to set the timer, the rotation cam 30 rotates in conjunction with the rotation of the rotation cam fixing pin 91. Thus, the counter ratchet 51 separates from the counter insertion groove 31, And is located on the outer periphery of the cam 30.

5 (c), after setting the time of the timer, the valve rotating shaft 60 is turned counterclockwise to open the ball valve 70 at an angle of 90 °, And is in a state immediately before insertion into the latch insertion groove 61. Referring to Fig. 5 (d), the ball valve 70 is completely opened and the valve rotation shaft 60 is completely restrained by the latching ratchet 52, so that the timer rotates counterclockwise for the set time. As shown in FIG. 5 (e), there is no change in the latch ratchet 52 and the counter ratchet 51 when the set time of the timer is nearly completed. 5 (b), after the set time of the timer has elapsed, the rotation cam 30 is instantaneously rotated by a certain angle by the rotation tolerance groove 32. At this time, the counter- (51) is inserted into the counter insertion groove (31), the latching ratchet (52) is momentarily rotated to release the valve rotating shaft (60) which has been restrained.

As a result, the two latching latches 52 and the counter ratchet 51 of the articulated type, the counter insertion groove 31 of the concave shape, and the rotation cam 30 formed with the rotation tolerance groove 32 are constituted, And the ball valve can be instantaneously and precisely controlled after the set time has elapsed.
