Description

上記のような課題を解決するため、この発明は、弁体の回動によって流体通路を開閉するバルブと、前記弁体を回動させるためのモータを備えた駆動機構と、前記駆動機構におけるモータの出力軸と弁体の弁軸を連結する接続機構と、前記駆動機構のモータを駆動するための電源を備え、この電源をモータと切換えスイッチを介して電気的に接続したコントローラとからなり、前記コントローラに、弁体が開位置になると点灯する開位置表示灯と、弁体が閉位置になると点灯する閉位置表示灯と、前記切換えスイッチの切換え時にモータと開位置表示灯又は閉位置表示灯に対して予め設定した時間だけ通電する制御回路を設け、前記制御回路に設定する通電時間を、弁体の開閉切換えに要する時間よりも長く設定し、弁体が開位置又は閉位置に停止した後も、長く設定した通電時間だけ開位置表示灯又は閉位置表示灯が点灯しているようにしたものである。 In order to solve the above-described problems, the present invention provides a valve that opens and closes a fluid passage by rotation of a valve body, a drive mechanism that includes a motor for rotating the valve body, and a motor in the drive mechanism. Comprising a connection mechanism for connecting the output shaft of the valve body and the valve shaft of the valve body, and a controller for driving the motor of the drive mechanism, and a controller that electrically connects the power supply to the motor via a changeover switch. The controller includes an open position indicator lamp that lights when the valve element is in the open position, a closed position indicator lamp that lights when the valve element is in the closed position, and a motor and an open position indicator lamp or a closed position indicator when the changeover switch is switched. a control circuit for energizing only time set in advance for the lamp is provided, the energizing time to be set in the control circuit, is set longer than the time required for opening and closing the switching of the valve body, the valve body is opened or closed position After stopping is also one in which open position indicator or closed position indicator only energization time set longer has to lit.

上記コントローラは、その内部に、取換え可能な乾電池を用いた電源と制御回路を収納し、外面に切換えスイッチと開位置表示灯及び閉位置表示灯が設けられ、上記モータとリミットスイッチ、各表示灯が電源と制御回路を介して電気的に接続されている。 The controller houses a power supply and control circuit using replaceable dry batteries inside, and is provided with a changeover switch , an open position indicator lamp and a closed position indicator lamp on the outer surface, the motor, limit switch, and each display. lighting is that is electrically connected via a power and control circuit.

更に、制御回路に設定する通電時間を、弁体の開閉切換えに要する時間よりも長く設定し、弁体が開位置又は閉位置に停止した後も、長く設定した通電時間だけ開位置表示灯又は閉位置表示灯が点灯するようにしたので、弁体が開又は閉になった後も所定時間だけ開位置表示灯又は閉位置表示灯が点灯していることになり、点灯時間を長くすることで弁体が開又は閉の位相表示を見逃すことが少なくなり、コントローラを操作の容易な位置に設置してバルブの開閉等を遠隔操作できると同時に、開又は閉の位相確認が可能になる。 Furthermore, the energization time set in the control circuit is set to be longer than the time required for switching the opening and closing of the valve body, and after the valve body stops at the open position or the closed position, the open position indicator lamp or Since the closed position indicator lamp is lit, the open position indicator lamp or the closed position indicator lamp is lit for a predetermined time after the valve element is opened or closed, and the lighting time is lengthened. Thus, it is less likely to miss the phase display of the opening or closing of the valve body, and the controller can be installed at an easy-to-operate position to remotely control the opening and closing of the valve, and at the same time, the phase of opening or closing can be confirmed.
