Description

메뉴얼 조작 양방향 클러치를 갖는 전동밸브장치{Manual operation Electro-hydraulic valve unit with bidirectional clutch}[0001] The present invention relates to an electro-hydraulic valve unit with bidirectional clutch,

본 발명은 메뉴얼 조작 양방향 클러치를 갖는 전동밸브장치에 관한 것으로서, 더욱 상세하게는 전동밸브장치에 있어서, 전동조작시 메뉴얼핸들이 동작되지 않게 매뉴엘핸들이 양방향클러치를 매개로 개폐나사축에 축결합되게 구성하여서, 밸브의 전동조작시 메뉴얼핸들의 동작으로 인한 안전사고를 방지할 수 있도록 함을 목적으로 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor-operated valve device having a manual operation bi-directional clutch, and more particularly, to a motor-operated valve device in which a manual handle is operated in an electrically operated operation, So as to prevent a safety accident due to the operation of the manual handle during the electric operation of the valve.

일반적으로, 전동밸브장치는 밸브의 개폐를 밸브컨트롤러에 의하여 제어되는 밸브모터에 의하여 자동으로 개방 또는 폐쇄되게 하는 것이다.Generally, the motor-operated valve device automatically opens or closes the opening and closing of the valve by a valve motor controlled by the valve controller.

이상과 같은 전동밸브장치는 유체의 유동을 제어하는 밸브와 상기 밸브의 축에 결합된 밸브전동구동부 및 상기 밸브전동구동부의 동작을 제어하는 밸브컨트롤러로 구성되는 것이다.The electromotive valve device as described above includes a valve for controlling the flow of fluid, a valve electric drive part coupled to the shaft of the valve, and a valve controller for controlling the operation of the valve electric drive part.

상기 밸브전동구동부는 밸브축에 결합된 밸브개폐암과 상기 밸브개폐암과 회동시켜 개폐조작이 이루어지게 하는 밸브개폐블록, 상기 배브개폐블록을 직선운동시키는 개폐나사축, 상기 개폐나사축과 감속기를 매개로 전동 결속된 밸브모터 및 상기 개폐나사축을 수동조작할 수 있게 구비되는 메뉴얼핸들로 구성되는 것이다.Wherein the valve driving unit includes a valve openable and closable block coupled to a valve shaft and a valve openable and closable block for pivotally opening and closing the valve openable and closable cylinder, an opening and closing screw shaft for linearly moving the valve openable and closable block, And a manual handle provided so as to manually operate the opening and closing screw shaft.

상기한 바와 같이 구성된 종래의 전동밸브장치는 밸브컨트롤러에 의하여 밸브모터가 구동되어서 감속기를 통하여 개폐나사축이 회전하면 밸브개폐블록이 직선운동을 하면서 밸브개폐암을 회전시켜 밸브가 개폐되게 하는 것이다.In the conventional motor-operated valve device configured as described above, when the valve motor is driven by the valve controller to rotate the opening / closing screw shaft through the speed reducer, the valve open / close block linearly moves and rotates the valve openable /

또한, 종래의 전동밸브장치는 메뉴얼 조작시 메뉴얼핸들을 돌려줌으로써 수동조작에 의하여 개폐나사축이 회전되어서 밸브개폐블록이 밸브의 개폐가 이루어지는 것이다.In addition, in the conventional motor-operated valve device, the manually operated handle is rotated by manual operation to rotate the opening / closing screw shaft so that the valve opening / closing block opens and closes the valve.

그러나, 상기한 바와 같은 종래의 전동밸브장치는 밸브모터에 의한 전동조작시 외부로 노출된 메뉴얼핸들이 함께 회전되어 안전사고의 위험이 높은 문제점이 있었다.However, in the conventional motor-operated valve device as described above, there is a high risk of a safety accident due to the rotation of the manual handle exposed to the outside during the motor-operated operation by the valve motor.

이러한 문제점을 해결하기 위하여 메뉴얼핸들을 제거한 후 따로 보관하였다가 사용하는 경우가 있으나 이는 메뉴얼핸들의 분실을 야기하고 메뉴얼핸들의 사용시 신속한 사용이 이루어지지 않는 문제점이 있었다.In order to solve such a problem, there is a case where the manual handle is removed and then stored and used separately. However, this causes a loss of the manual handle and a problem that the manual handle is not used promptly.
