弁のストツパー構造。[Claims for Utility Model Registration] By energizing the stator coil 10 of the motor fixed to the outer periphery of the case 9 made of a non-magnetic material, the valve stem 1 having the male thread 4 housed in the case 9 is integrated. The formed rotor 5 of the motor is rotated, and this rotation is applied to the valve shaft 1 by a propulsion bearing 8 having a female thread 7.
In the motor-operated valve that controls the opening degree of the valve seat 2 by converting it into a linear motion, the inner peripheral surface of the rotary sleeve 15, which is integrated with the rotor 5 of the motor, is made to protrude in the radial direction at only one location. A convex portion 15a is integrally formed therein, and a retaining pin 16 is fixed to the inner surface of the lid 13 at a distance from the center by hanging down to the middle of the convex portion.
In the range of less than one revolution of the motor rotor,
The movement of the valve stem is regulated by bringing the retaining pin 16 into contact with the side surface of the convex portion 15a, and when the valve is fully opened, the tip 3a of the needle valve 3 is 0.5 degrees lower than the valve seat 2.
A stopper structure for an electric valve that is characterized by a stopper structure that allows it to come out more than mm.
