본 발명은 전동 액츄에이터 작동상태 표시장치에 관한 것으로, 액츄에이터의 작동상태가 닫힘 상태인지 열림 상태인지를 돔형 표시부를 두어 확인 가능토록 하고, 표시부를 일정 각도마다 분할하여 어느 위치에서도 즉시 인식 가능토록 한 전동 액츄에이터 작동상태 발광 표시장치에 관한 것이다.The present invention relates to an electric actuator operating state display device, and to determine whether the operating state of the actuator is in the closed state or the open state with a dome-shaped display unit, and by dividing the display unit at a predetermined angle so that it can be immediately recognized at any position An actuator operating state light emitting display device.

일반적으로 버터플라이 밸브와 볼 밸브 등의 밸브류와 댐퍼 등의 회전기기 등을 개폐하는데 사용하는 액츄에이터는 외부로부터 입력되는 전기적인 신호에 의해 작동하고, 이 전기적인 신호는 통상 마이크로 스위치를 통해 전달받으며, 상기의 밸브 및 회전기기를 약 90°의 범위 내에서 전동 또는 수동으로 회전시켜 개폐하게 된다.In general, actuators used to open and close valves such as butterfly valves and ball valves, and rotary devices such as dampers are operated by an electrical signal input from the outside, and the electrical signals are generally transmitted through a micro switch. The valve and the rotary device are opened and closed by rotating the motor or manually in the range of about 90 °.

또한, 이러한 액츄에이터에는 밸브로부터 전달되는 역토오크에 의한 회전을 방지하기 위하여 이중 웜기어에 의한 셀프 록킹(Self-locking) 장치와, 수동 및 전동모드 전환장치, 과부하 및 과전류 보호장치, 응축 및 응결수 방지를 위한 히터 등이 내장되어 있어서 항상 최적의 운전상태를 유지하도록 되어 있다.In addition, these actuators have a self-locking device with dual worm gears, manual and electric mode switching devices, overload and overcurrent protection devices, and condensation and condensation water protection to prevent rotation by reverse torque transmitted from the valve. Built-in heater, etc. for maintaining the optimum operating state at all times.

이중, 수동 및 전동모드 전환장치는 밸브 또는 회전기기를 개폐함에 있어 모터의 동력이나 핸들 수작업 중 어느 한 가지를 선택하여 밸브를 개폐할 수 있도록 하는 장치로서, 수동/전동모드의 전환여부에 따라 밸브개폐를 모터의 동력 또는 수작업으로 실시할 수 있다. 수동/전동 동작 후 사용자는 정상 작동을 했는지 확인하게 되는데 이대 사용되는 것이 작동상태 표시창이다.Dual, manual and electric mode switching device is a device that can open and close the valve by selecting any one of the power of the motor or the handle manual operation in opening and closing the valve or rotary machine, depending on whether the manual / motor mode switching Opening and closing can be performed by motor power or by hand. After the manual / motor operation, the user checks the normal operation. This is the operation status display window.

기존의 표시장치는 도 1a 의 평면도 및 도 1b 의 단면도와 같이 하우징(1)에 투명의 표시창(20)을 결합시키고, 표시창(20)의 하부에는 발광용 램프(11)를 수용하는 표시구(10)를 안치시킨다 .물론 표시구(10)는 밸브레버와 연동하여 밸브레버의 개폐를 나타내는 형태로 구성하되, 밸브레버의 상단에 결합시킨다.Existing display devices are coupled to the transparent display window 20 in the housing 1, as shown in the plan view of Figure 1a and cross-sectional view of Figure 1b, the lower portion of the display window 20 to accommodate the light emitting lamp 11 ( 10) of course. Of course, the indicator 10 is configured in the form of opening and closing the valve lever in conjunction with the valve lever, it is coupled to the upper end of the valve lever.

따라서 2차웜샤프트(71)에 끼움 결합하여 동시에 작동하는 여닫기 표시구(312)가 90도로 회전하면(예를 들어 표시부(a1)가 열림창(313-1)으로 노출되어 닫힘상태인지를 표시하고 있다가, 표시부(a1)가 표시부(c1)위치로 이동하면, 표시부(a1)는 닫힘창(313-2)에 닫히고, 대신 닫혔던 표시부(c2')가 열림창(313-1)의 표시부(b2)를 통하여 열림 상태인지를 나타낸다.Therefore, when the opening and closing indicator 312 that is simultaneously engaged by fitting to the secondary worm shaft 71 is rotated by 90 degrees (for example, the display part a1 is exposed to the opening window 313-1 to indicate whether it is in a closed state and Then, when the display portion a1 moves to the position of the display portion c1, the display portion a1 is closed by the closing window 313-2, and the display portion c2 'which has been closed instead is displayed on the display portion 313-1 of the opening window 313-1. b2) indicates whether it is open.

결국 본원 발명은 여닫기 표시구(312)를 돔형으로 두고 수직벽의 중간 기준선을 두고 상하로 상호 반대의 위치를 표시하는 표시부를 두고, 표시부에 대응하는 위치에 열림창(313-1)을 이룬 독특한 돔형 구조의 개폐창(313)을 사용하기에 90도 를 회전하여도 측면과 상면에서 동시에 열림과 닫힘의 상태를 알려주어 사용자가 쉽게 인식가능토록 하는 편리함을 제공한다.As a result, the present invention has a display unit which displays the opening and closing holes 312 in a dome shape and displays the mutually opposite positions up and down on the middle reference line of the vertical wall, and forms an opening window 313-1 at a position corresponding to the display unit. Even when the opening and closing window 313 of the dome-shaped structure is rotated by 90 degrees, the state of opening and closing at the same time on the side and the upper surface provides convenience for the user to easily recognize.

본원발명은 여닫기 표시구(312)의 내면에 상응하는 2차웜샤프트(71)부위에는 수직으로 발산하는 엘이디 등의 조명등인 조명램프 표시기(315)를 수개 설치하여 반투명의 여닫기 표시구(312)를 비춰주면 이 상태가 열림창(313-1)을 통하여 투명한 표시창(311)에 그대로 나타나게 된다.The present invention is installed on the secondary worm shaft 71 corresponding to the inner surface of the opening indicator 312 by installing several illumination lamp indicators 315, such as LED lamps that emit vertically translucent opening indicator 312 In this case, this state is displayed on the transparent display window 311 through the opening window 313-1.

이상과 같이 본원 발명은 여닫기 표시구를 돔형으로 구성하고, 표시구의 수직벽 중간기준선을 중심으로 상하 표시부를 두며, 각 표시부가 수직 위치에서는 상호 반대의 위치를 표기토록 하고, 표시부의 표시 상태를 개폐하는 개폐창은 역시 수직위치에서 상하 반대로 닫힘창과 열림창을 두어 여닫기 표시구의 표시 상태가 상하에서 선택한 위치가 표기되고, 열림창과 닫힘창의 위치가 90도 마다 상호 반대로 오도록 하여, 사용자는 측면과 상면 어느 위치에서도 여닫기 표시구의 표시부 상태를 쉽게 볼 수 있어, 사용시의 오동작을 막을 수 있게 된다. As described above, the present invention constitutes the opening and closing display sphere in a dome shape, and has an upper and lower display portion centered on the middle reference line of the vertical wall of the display sphere, and allows each display portion to mark the opposite positions at the vertical position, and opens and closes the display state of the display portion. The opening and closing window is also placed vertically in the vertical position, the closing window and the opening window, the display state of the opening and closing indicator is displayed in the position selected from the top and bottom, and the position of the opening window and the closing window is opposite to each other by 90 degrees, so that the user The position of the display portion of the opening and closing indicator can be easily seen even at the position, thereby preventing malfunction in use.
