バルブ。 The needle valve, which is brought into contact with and separated from the valve seat of the valve body, is brought into contact with and separated from the valve seat by the rotation of a rotor supported by a screw tube, and the end of the needle valve is passed through a hole in the connecting plate of the rotor, and one side thereof is A stopper is provided on one part, a spring receiver is provided movably on the other side, a coil spring is provided between the spring receiver and the needle valve to bias the valve in the valve closing direction, and a spacing member is provided between the spring receiver and the stopper. An electric control valve characterized in that when the valve is opened and closed, the spacing member comes into contact with the stopper, thereby separating the spring receiver from the connecting plate.
