본 고안은 모터의 회전범위를 구동기어상 스위치탄편과 회로기판상 회전범위표시 박막부와의 물리적인 접촉상태에 따라 밸브개폐 구동축 90°또는 180°회전후 정지되면서 밸브개폐가 이루어지게된 모터를 이용한 밸브개폐 장치에 관한 것이다.According to the present invention, the motor opens and closes the valve by opening or closing the valve opening / closing drive shaft 90 ° or 180 ° according to the physical contact state between the switch bullet on the drive gear and the thin film part on the circuit board. It relates to a valve opening and closing device.

종래이 종류의 밸브개폐장치로는 마이크로 스위치를 내장하여 모터의 전원을 차단시킴으로써 밸브개폐가 이루어지게 한 것과 또는 모터의 축상에 다수의 돌기를 갖은 회전판을 고정시켜 돌기의 간격만큼에서 밸브개폐가 이루어지도록 된 것이었으나, 이는 전기의 과부하가 발생하여 전기소모가 크고, 모터의 고장이 자주 발생하는문제점이 있어서, 본 고안은 이러한 문제점을 해소하기 위해 안출된 것으로서, 밸브개폐 구동축상의 구동기어에 스위치탄편을 설치하고, 회로기판상에 회전기판상에 회전범위표시 박막부를 형성하여 이들이 서로 물리적으로 접촉됨에 따라 모터의 구동을 제어할 수 있도록 함으로써, 영구자석형 피엠(P.M) 교류모터 등과 같이 기동시 정,역 어느 방향으로 회전할 경우 또는 일방향회전시 정확한 밸브개폐 위치에 서 모터를 정지시킬 수 있게끔 고안된 것이다.The conventional type of valve opening and closing device is to open and close the valve by cutting off the power of the motor by incorporating a micro switch, or to open and close the valve at the interval of the protrusion by fixing a rotating plate having a plurality of protrusions on the shaft of the motor. However, this is due to the problem that the electrical overload occurs, the electrical consumption is large, and the motor failure frequently occurs, the present invention was devised to solve such a problem, the switch piece on the drive gear on the valve opening and closing drive shaft It is installed on the circuit board, and the rotation range display thin film is formed on the rotating board to control the driving of the motor as they are in physical contact with each other. When rotating in either direction or in one direction, move the motor in the correct valve opening position. It is designed to stop.

이하 본 고안을 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안을 밸브상에 장착시킨 상태를 단면도시한 것이고, 제2도는 기어연동구성을 나타낸 평면도이며, 제3도는 본 고안의 요부분리 사시도이다.1 is a cross-sectional view showing a state in which the present invention is mounted on a valve, and FIG. 2 is a plan view showing a gear linkage configuration, and FIG. 3 is a partial perspective view of the present invention.

밸브(1)상부의 개폐축(2)상에 개폐손잡이(12)가 설치되어 이 손잡이로 개폐동작이 이루어지게 됨은 통상의 밸브개폐 구조와 같다.Opening and closing handle 12 is installed on the opening and closing shaft (2) of the upper part of the valve (1) is the opening and closing operation is made by this handle is the same as the conventional valve opening and closing structure.

본 고안은 이러한 밸브상부에 개폐축(2)으로 연장되는 구동축(2’)과 이 구동축(2’)상에 축착되어 정,역모터(도시없음)로 부터의 구동력을 감속기어(8)들을 통해 회전력을 부여받는 구동기어(3)에 있어서, 이구동기어(3)상부에 고정설치되어 회로기판(5) 표면과 접촉대면 되는 스위치탄편(4)과, 회로기판(5)상 위 스위치탄편이 접촉되는 부분에 회전범위표시 박막부(6)로 이루어진 밸브개폐범위 조절구도가 장치됨을 특징으로 한 것으로, 회로기판(5)상 회전범위표시 박막부(6)는 밸브개폐축(2)상 연장된 구동축(2’)의 회전범위를 90°혹은 180°로 조절할 수 있도록 정,역모터의 구동제어회로(7)와 연결되는데, 그 상태는 제4a,b도 및 제5b,c도에 잘 도시되어 있다.According to the present invention, the driving shaft 2 'extending to the opening / closing shaft 2 above the valve and the driving shaft 2' are fixed on the driving shaft 2 'to reduce the driving force from the forward and reverse motors (not shown). In the drive gear (3) to which the rotational force is applied, the switch bullet piece (4) fixedly mounted on the upper driving gear (3) and facing the surface of the circuit board (5) and the switch bullet piece on the circuit board (5) are The valve opening and closing range adjustment mechanism consisting of the rotation range display thin film portion 6 is provided on the contact portion, and the rotation range display thin film portion 6 on the circuit board 5 extends on the valve opening and closing shaft 2. It is connected to the drive control circuit 7 of the forward and reverse motors to adjust the rotation range of the driven drive shaft 2 'to 90 ° or 180 °, and the state is well shown in FIGS. 4a, b and 5b, c. Is shown.

스위치탄편(4)은 단부가 여러갈래로 나뉘어져 2개 1조씩 위 회전범위표시 박막부(6)에 대응되게 되어있다.The switch piece piece 4 is divided into several parts at an end thereof so as to correspond to the upper rotation range display thin film portion 6 by two sets.

이와같이 구성된 본 고안은 모터가 구동되면 감속기어(8)들을 통해 구동기어(3)가 회전되어 구동축(2’) 즉, 개폐축(2)이 회전되어 구동축(2’) 즉, 개폐축(2)이 회전됨에 따라 밸브(1)의 개폐가 이루어지게 되는데, 이때 구동기어(3)상 스위치탄편(4)이 제4a,b도와 같이 회로기판(5)상 3단 동심원(9a)(9b)(9c)으로 이루어지고 바깥원(9a)과 중간원(9b)의 단락부(11)가 중심점(0)으로부터 90°각도로 설정된 회전범위 표시 박막부(6A)에 접촉대면되게 되면 모터 구동제어회로(7)에 의해 정,역방향으로 90°회전후 정지하게 됨으로써, 개폐스위치(S)를 어느쪽으로 하여도 밸브개폐위치에서 정확히 모터가 정지하게 되며, 제5a,b도와 같이 회로기판(5)상 3단 동심원(10a)(10b)(10c)으로 이루어지되, 바깥원(10a)과 중간원(10b)의 단락부(11)가 중심점(0)으로부터 180°각도로 설정된 회전범위표시 박막부(6B)에 접촉대면될 경우에는 모터구동제어회로(7)에 의해 180회전후 정지하게 되므로 마찬가지로 개폐스위치(S)를 어느쪽으로 하더라도 모터는 밸브개폐 위치에서 정확하게 정지하게되며 과부화가 발생하지 않는다. 한편 정전 또는 고장에 의해 전원이 끊길 경우에는 별도 개폐손잡이(12) 결합하여 수동 조작에 의해 밸브 개폐를 하면 된다.According to the present invention configured as described above, when the motor is driven, the driving gear 3 is rotated through the reduction gears 8 so that the driving shaft 2 ', that is, the opening and closing shaft 2, is rotated so that the driving shaft 2', that is, the opening and closing shaft 2 is rotated. As the valve 1 rotates, the valve 1 is opened and closed. At this time, the switch carbon piece 4 on the drive gear 3 is concentric circles 9a and 9b on the circuit board 5 as shown in FIGS. 4a and b. Motor driving control when the short circuit portion 11 of the outer circle 9a and the middle circle 9b is brought into contact with the rotation range display thin film portion 6A set at an angle of 90 ° from the center point 0. By stopping by 90 ° in the forward and reverse directions by the circuit 7, the motor stops exactly at the valve opening / closing position regardless of which opening / closing switch S is used. As shown in Figs. 5a and b, the circuit board 5 Rotation range consisting of phase 3 concentric circles (10a) (10b) (10c), the short circuit portion 11 of the outer circle (10a) and the intermediate circle (10b) is set at an angle of 180 degrees from the center point (0) In the case of contacting the display thin film portion 6B, the motor drive control circuit 7 stops the motor after 180 rotations. Therefore, even if the on / off switch S is turned to the same position, the motor stops accurately at the valve opening and closing position and overload occurs. I never do that. On the other hand, when the power is cut off due to power failure or failure, it is possible to open and close the valve by manual operation by combining the opening and closing handle 12 separately.

이와같이 본 고안은 밸브개폐 범위를 정확하게 조절할 수 있으며, 밸브개폐 위치에서 모터를 정지시킬 수 있게되고, 기존의 기계적 작동에 의하여 모터를 정지시킴으로서, 발생되던 전기전과부하 발생을 막고 전기소모를 최대한 방지할 수 있게된 잇점을 제공 하게되었다.In this way, the present invention can precisely control the valve opening and closing range, stops the motor at the valve opening and closing position, and stops the motor by the existing mechanical operation, thereby preventing the occurrence of electric overload generated and preventing electric consumption as much as possible. It provides the benefits that are possible.
