Claims

[Scope of utility model registration request]

A rotating shaft is installed perpendicularly to the diaphragm for opening and closing the valve, a rotating gear is attached to the rotating shaft, and a motor drive gear for rotating the rotating shaft in the forward or reverse direction is engaged with the rotating gear. , a bearing is arranged below the rotating gear, the rotating shaft is rotatably and slidably inserted into the bearing, the bearing is brought into contact with the lower surface of the rotating gear, and the bearing is pushed down above the rotating gear. Arrange a spring to push the rotating shaft down toward the bearing side, carve a lower screw on the rotating shaft below the rotating gear, and carve an upper screw on the rotating shaft above the rotating gear. The opening/closing nut part for operating the diaphragm, which is attached to the diaphragm and moves up and down with the rotation of the rotating shaft, is screwed into the lower screw, and an opening switch nut and a closing switch nut are installed, which move up and down with the rotation of the rotating shaft. A forward rotation stop switch and a reverse rotation stop switch are installed by screwing into the upper screw, and are turned on and off by raising and lowering the open or close switch nut, and stop the motor in the forward or reverse rotation. An electric opening/closing valve device comprising an emergency stop switch that detects a rotating shaft that rises as the motor rotates in an emergency such as when something gets caught, and stops the motor in an emergency.
