「産業上の利用分野」
本考案は、回動に伴つて流路を開閉する弁体を
回動操作する電動モータと、前記電動モータを作
動制御する制御手段を設ける電動弁に関する。[Detailed description of the invention] "Industrial application field" The present invention includes an electric motor that rotates a valve body that opens and closes a flow path as it rotates, and a control means that controls the operation of the electric motor. Regarding electric valves.
「従来の技術」
従来、例えば、ゴルフ場や田畑において潅漑の
ために用いられる散水栓を離れた箇所から自動的
に開閉できるように、回動に伴つて流路を開閉す

操作する場合、閉状態にある位置から90度回動操
作することにより開状態に、且つ、その開状態に
ある位置から90度戻すことにより閉状態に、夫々
切換え操作するように構成されていた。``Prior Art'' Conventionally, for example, a valve element that opens and closes a flow path as it rotates is driven by an electric motor, so that water faucets used for irrigation at golf courses and fields can be automatically opened and closed from a remote location. However, when opening and closing a valve body such as a ball valve using an electric motor, it is necessary to rotate the valve body 90 degrees from the closed position to open it. They were configured so that they could be switched to the closed state by returning 90 degrees from the original position.
「考案が解決しようとする問題点」

くとも３本の電源線を電動モータにスイツチを介
して接続させる必要がある等の問題があつた。``Problems to be solved by the invention'' In the prior art, the valve body was configured to rotate back and forth within a range of 90 degrees to switch between the open state and the closed state. Pressed toward the downstream side of the flow path, only the outer circumferential portion of the valve body corresponding to the downstream side of the flow path slides while being strongly pressed against the valve case, which is likely to wear out quickly and reverse the polarity of the electric motor. Since the valve body is rotated in the forward and reverse directions, there are problems such as the need to connect at least three power lines to the electric motor via switches.

る。``Means for Solving the Problems'' However, the present invention provides a power supply unit that reverses the polarity of DC power and outputs it for each activation command in an electric valve whose valve body is rotated by an electric motor to open and close the valve. , a rectifier that applies DC power to the electric motor with the same polarity regardless of the output polarity of the power supply section, and a switch that automatically stops the electric motor by turning on and off in conjunction with the opening/closing operation of the valve body. The valve body is characterized in that the valve body is configured to be rotated in one direction by a predetermined angle by a motor.
「作用」
従つて、弁体を一方向にのみ回動操作しながら
流路を開閉するので、弁体外周部の各部分が流路

モータを用いる弁体開閉構造に比べて電源配線数
を容易に削減し得るものである。``Operation'' Therefore, since the flow path is opened and closed while rotating the valve body in only one direction, each part of the outer circumference of the valve body is positioned on the lower side of the flow path, and the entire valve body is uniformly spread. It can be used in a state where it wears out, and the durability of the valve body is significantly improved compared to the conventional one, and the output polarity of the power supply section is reversed to operate the electric motor.
Power can be supplied to the motor using the main power wiring, and power consumption can be easily reduced compared to a conventional valve body opening/closing structure using a solenoid, and compared to a conventional valve body opening/closing structure using a reversible motor. Therefore, the number of power supply wiring can be easily reduced.
