1. one kinds of water turbine water stop ring double follow-up water sealing devices is characterized in that:

  • First grade axis to the double follow-up double sealing structure is;

    the static guide plate of one-level that has two ring-like guide grooves puts together on the main shaft, be fixed on the cover of top, two constant voltage water-filling elastic rubber pipes are placed on the bottom of two ring-like guide grooves respectively, two brilliant ring-like seals of static distinguish carbon lay respectively on two constant voltage water-filling elastic rubber pipes, fix by standstill seal body positioning screw, the one-level distinguish that has two ring-like guide grooves rotates guide plate and puts together on the main shaft of the static guide plate of one-level top, two hollow elasticity caulking gum pipes lay respectively at the bottom of two ring-like guide grooves, two brilliant seals of the ring-like carbon of distinguish lay respectively at outside two hollow elasticity caulking gum pipes, half sealed body positioning screw is fixed on the one-level distinguish and rotates in the ring-like guide groove of guide plate, and half inserts in the ring-like guide groove of the static guide plate of one-level;

    Secondary radially double follow-up list sealing is;

    the secondary rotation distinguish guide plate that has a ring-like guide groove puts together on the one-level distinguish and rotates on the main shaft of guide plate top, hollow elasticity caulking gum pipe is placed on the bottom of ring-like guide groove, the brilliant seal of the ring-like carbon of distinguish is positioned at outside the hollow elasticity caulking gum pipe, be fixed in the ring-like guide groove with distinguish seal positioning screw, divide the flap seal carrying cylinder to be positioned at the outside of first grade axis to the double follow-up double sealing structure, the lower end is fixed on the cover of top, the static distinguish guide plate of secondary that has a ring-like guide groove puts together on the upper end of branch flap seal carrying cylinder, ring-like hollow elasticity caulking gum pipe is placed on the bottom of ring-like guide groove, the brilliant seal of the ring-like carbon of distinguish is positioned at outside the ring-like hollow elasticity caulking gum pipe, be fixed in the ring-like guide groove the brilliant seal end face of the ring-like carbon of the distinguish driving fit of its end face and the ring-like guide groove of secondary rotation distinguish guide plate with distinguish seal positioning screw;

    The constant voltage damping device is;

    fix a pressure-resistant seal rubber bag tank in constant voltage tube upper end, a pressing plate is put in the upper end of pressure-resistant seal rubber bag tank, is enclosed within on the pressing plate guide rod, and the pressing plate guide rod is fixed on pressure-resistant seal rubber bag tank both sides, on the constant voltage tube;

    Passed the constant voltage water-filling elastic rubber pipe of branch flap seal carrying cylinder and ring-like guide groove of the static guide plate of one-level and guide groove bottom connects by constant voltage tube bottom water pipe;

    The brilliant seal of the ring-like carbon of distinguish end is with square hollow seal rubber pipe sealing.
