とを特徴とする電動弁の針状弁部構造。 When the stator 10 of the motor is energized, its rotation is converted into a linear movement of the valve stem 1 by the external thread 4 formed on the valve stem 1, and when the valve stem 1 is fully closed, the needle valve 3 is pressed against the valve seat 2 by the spring 14. In the electric valve that is in contact with the valve shaft 1 integrally formed with the rotor 5 of the motor.
The tip of the needle valve 3 is opened to provide a deep hole 16, and the inner part of the hole is formed into a smooth surface.On the other hand, a concave ring groove 15 is provided in the upper shaft of the needle valve 3, and a deep hole 16 is formed in the shaft of the needle valve 3. Insert the ball 23 and spring 1 into the hole 16.
4 and the shaft of the needle valve 3, and the outer periphery of the valve shaft 1 corresponding to the concave ring groove 15 is so that the needle valve 3 can rotate and move up and down within the range of the concave ring groove 15. A needle valve structure of an electric valve characterized by being fixed by caulking.
