Abstract

A stopper in a valve actuator is provided to be used by being mounted on an actuator without a stopper since an additionally manufactured stopper device is easily mounted on a conventional actuator. A stopper in a valve actuator includes a rotation stopper(10) and a pair of stopping members(22). The rotation stopper is rotatably formed together with a rotational shaft(2) to open and close a channel of a valve by an operation of an actuator(1). The stopper surface is formed on one side of the rotation stopper. The stopping members limit the rotation angle of the rotation stopper by being in contact with the stopper surface of the rotation stopper. The stopping members have a clockwise stopping member and a counter clockwise stopping member to limit the rotation angle of both direction of the rotation stopper, respectively.

The two stopper surfaces 12 are formed at predetermined angles along the circumferential direction of the rotary stopper 10, respectively. Each stopper surface 12 is brought into contact with the engaging members 21 and 22 at the time of the clockwise rotation and the counterclockwise rotation of the rotary stopper 10, respectively.

상기 걸림부재(21)(22)는 회전스토퍼(10)의 스토퍼면(12)과 접촉하여 회전각을 제한하게 된다.The locking members 21 and 22 contact the stopper surface 12 of the rotary stopper 10 to limit the rotation angle.

상기 걸림부재(21)(22)는 상기 회전스토퍼(10)의 양쪽 방향의 회전각을 각각 제한하는 시계방향 걸림부재(21) 및 반시계방향 걸림부재(22)를 포함한다.The locking members 21 and 22 include a clockwise locking member 21 and a counterclockwise locking member 22 for respectively limiting rotation angles in both directions of the rotary stopper 10.

도 5 및 도 6에 도시된 바와 같이, 상기 시계방향 걸림부재(21)는 상기 회전스토퍼(10)가 시계방향으로 회전할 때 하나의 스토퍼면(12)과 접촉하여 회전스토퍼(10)의 시계방향의 회전을 저지하게 된다. As shown in FIGS. 5 and 6, the clockwise engaging member 21 contacts one stopper surface 12 when the rotary stopper 10 rotates in a clockwise direction so that the clock of the rotary stopper 10 may be reduced. The rotation of the direction is prevented.

이와는 반대로, 상기 반시계방향 걸림부재(22)는 상기 회전스토퍼(10)가 반시계방향으로 회전할 때 다른 스토퍼면(12)과 접촉하여 회전스토퍼(10)의 반시계방향의 회전을 저지하게 된다.On the contrary, the counterclockwise locking member 22 contacts the other stopper surface 12 to prevent the counterclockwise rotation of the rotary stopper 10 when the rotary stopper 10 rotates counterclockwise. do.

That is, when the clockwise locking member 21 and the counterclockwise locking member 22 are screwed or loosened, the distance to the stopper surface 12 of the rotation stopper 10 can be adjusted, thereby rotating. The allowable angle at which the stopper 10 rotates can be adjusted.

걸림부재(21)(22)를 조여 스토퍼면(12)과의 거리를 좁이게 되면 회전스토퍼(10)의 회전각이 작아지고, 이와 반대로 걸림부재(21)(22)를 풀어 스토퍼면(12)과의 거리를 멀게 하면 회전스토퍼(10)의 회전각이 커지게 되는 것이다. When the locking member 21, 22 is tightened to narrow the distance from the stopper surface 12, the rotation angle of the rotary stopper 10 becomes smaller. On the contrary, the locking member 21, 22 is released to release the stopper surface 12. If the distance to the far away) will be to increase the rotation angle of the rotary stopper (10).

The coupling bracket 50 is detachably screwed to the support member 30 to mount the device. It is used in combination with the support member 30 only when necessary. Devices that need to be mounted are piece-coupled to the coupling bracket 50.

이상에서 설명한 바와 같이 본 발명에 따른 밸브 액츄에이터의 스토퍼장치에 의하면, 액츄에이터에 의해 작동하는 밸브 회전축의 회전각도를 제한할 수 있게 되고, 그로 인해 회전축에 의한 디스크의 개폐동작을 정확하게 제어하여 유체의 유출을 방지할 수 있는 효과가 있다.As described above, according to the stopper device of the valve actuator according to the present invention, it is possible to limit the rotation angle of the valve rotating shaft operated by the actuator, thereby precisely controlling the opening and closing operation of the disk by the rotating shaft, thereby allowing the fluid to flow out. There is an effect that can prevent.

또한, 본 발명에 의하면, 본 발명에 따른 스토퍼장치를 별도로 제작하여 기존의 액츄에이터에 간편하게 장착시킬 수 있게 됨으로써 스토퍼가 구비되지 않았던 액츄에이터에 장착하여 사용할 수 있는 효과가 있다.In addition, according to the present invention, the stopper device according to the present invention can be manufactured separately and can be easily mounted on an existing actuator, so that the stopper device can be mounted and used on an actuator that is not provided with a stopper.
