1. a mortor operated valve, possesses:

  • Valve casing, this valve casing forms columned valve chamber, and has opening portion a side of above-mentioned valve chamber and have seat portion the opposing party;

    Rotor case, forms columned rotor chamber around the above-mentioned opening portion that this rotor case is fixed on above-mentioned valve casing;

    Rotor, this rotor has rotor shaft on the axial direction of above-mentioned rotor chamber and above-mentioned valve chamber, can rotate and can be configured in above-mentioned rotor chamber in the axial direction movably;

    Stator coil, this stator coil is assemblied in the periphery of above-mentioned rotor case and drives above-mentioned rotor to rotate;

    Supporting part, this supporting part is fixed on the above-mentioned opening portion of above-mentioned valve casing and divides above-mentioned valve chamber and above-mentioned rotor chamber, and supports the above-mentioned rotor shaft of above-mentioned rotor;

    AndValve body, this valve body is located at the above-mentioned seat portion side of above-mentioned rotor shaft,Above-mentioned rotor is rotated, utilize the feed screw mechanism of above-mentioned supporting part and above-mentioned rotor shaft that above-mentioned rotor and rotor shaft are moved in the axial direction, above-mentioned valve body is utilized to increase and decrease the aperture of the valve port of above-mentioned seat portion, and utilize all pressures path by above-mentioned valve chamber and above-mentioned rotor chamber conducting, when above-mentioned rotor moves in the axial direction, above-mentioned valve chamber and above-mentioned rotor chamber is made to realize all pressingThe feature of said electric valve is,Above-mentioned supporting part has;

    be entrenched in the embedding part in the above-mentioned opening portion of above-mentioned valve casing;

    And be fastened on above-mentioned valve casing above-mentioned opening portion surrounding ends on lip part,Above-mentioned lip part is formed with the guiding path at above-mentioned rotor chamber side opening, the external diameter established amount less of the internal diameter of the inner peripheral surface of above-mentioned valve casing of the periphery of above-mentioned embedding part,Utilize the gap of the inner peripheral surface of the periphery of above-mentioned embedding part and above-mentioned valve casing and above-mentioned guiding path, form and above-mentionedly all press path,Gap between the periphery of above-mentioned embedding part and the inner peripheral surface of above-mentioned valve casing is formed in the whole circumference of the periphery of above-mentioned embedding part, and is to prevent allotrylic size.
