本考案は、弁を開閉するための電動操作機、特
にその開度位置検出装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electric operating machine for opening and closing a valve, and particularly to an opening position detection device thereof.

Electric operating machines used for valves, especially ball valves and butterfly valves, open and close the valve by rotating it 90 degrees, and a combination of a limit switch and a cam is used to detect the opening position.

Therefore, the valve body of the valve (not shown) rotates to perform opening/closing operations. Cams 7a and 7b are fixed to the output shaft 5 and rotate together with the output shaft 5. A limit switch 6 is installed on the cams 7a and 7b.
cams 7a and 6b are arranged in series, and the drive of the motor 1 is stopped depending on the rotational position of the cams 7a and 7b. In the known electric operating machine, the cam 7a,
In addition to limit switches 7b, limit switches 6a and 6b are fixed to an operating machine base 13, and all wiring for the limit switches, capacitor, motor, and other accessories is soldered using electric wires. Therefore, after all parts have been assembled into the electric operating machine, the cam has to be adjusted (to ensure that the valve is fully open, fully closed, or the limit switch operates at the intended opening).
従来の電動操作機では、配線はモータを含めて

In conventional electric operating machines, all wiring, including the motor, is done by soldering the wires, which sometimes results in wiring errors, and the wires are difficult to handle, resulting in a significant decline in work efficiency.

り、結果的には非常に非経済的である。 In addition, if a problem occurs such as the limit switch not working properly, the limit switch wiring must be rewired and readjusted, but since all the wiring is soldered, firstly it is a hassle to remove it, and then it is difficult to re-wire it. Adjustment requires specialized knowledge. Therefore, if such a problem occurs at a site where the valve is actually used, a technician with specialized knowledge is required. Until this specialized engineer is dispatched, the valve cannot be used, which is extremely uneconomical.

In the present invention, in order to solve the above problem, the wiring is made into a printed circuit board, the limit switch and the motor capacitor are fixed on the printed circuit board, and the cam device is attached to the printed circuit board through a cover. In addition, it is characterized in that the output shaft of the electric operating machine, the camshaft, and the cam device are configured to be separate and removable.

7b is fixed to a camshaft 8, and further, this camshaft 8 is rotatably fixed to a cover 9. The cover 9 is fixed to the printed circuit board 1, and although it is fixed with screws in this embodiment, it is not limited to this. Limit switch 6a, 6b
is turned on and off by the convex portions 14 of the cams 7a and 7b.
It is fixed to the printed circuit board 11 at an appropriate distance from the cams 7a and 7b. It is desirable that the limit switches 6a, 6b be directly fixed to the printed circuit board 11 by soldering. A capacitor 10 is similarly fixed to this printed circuit board 11, and a limit switch 6 is connected to the capacitor 10.
A and 6b are wired using a printed pattern. Furthermore, the printed circuit board 11 is attached to the mounting plate 1.
2, and the plate 12 is similarly fixed to the base 13 of the electric operating machine.

軸8は取り外し可能の構造となつている。 A recessed groove 16 is provided at the opposite end 15 of the output shaft 5 connected to the valve, and a convex portion 18 that engages with the recessed groove 16 is formed at the end 17 of the camshaft 8 . Therefore, in conjunction with the rotation of the output shaft 5, the camshaft 8 (therefore, the cams 7a, 7b) rotates. Further, the output shaft 5 and the camshaft 8 have a removable structure.

Figure 3 shows the wiring of a general electric operating machine. P within the dashed-dotted line frame is a portion to be processed on the printed circuit board, and the portion indicated by a broken line within the frame is a portion where wiring was conventionally performed using electric wires. Therefore, by mounting the limit switch and the motor capacitor on the printed circuit board, the number of electric wires is greatly reduced, connection errors are less likely to occur, and work efficiency is dramatically improved. In addition, when assembling the electric actuator, all you have to do is attach the cover with the cam and camshaft, the limit switch, and the capacitor to a printed circuit board in advance, and then attach the printed circuit board to the electric actuator, so there is no hassle associated with conventional assembly. .

易にできる。 Furthermore, by attaching the cam to the printed circuit board together with the cover, it is possible to improve the contact between the limit switch and the cam. Furthermore, even if a problem occurs with the limit switch, it is only necessary to replace it with a new printed circuit board equipped with an already adjusted limit switch, eliminating the need for conventional troublesome readjustments and making repairs easy even without specialized knowledge.
