A kind of ceramic ball valve of stabilized structure, it comprises body, spheres of ceramic and valve rod in valve body, ceramic valve seat, pottery, described valve body by left valve barrel, right valve barrel and in valve body form, in described pottery, body is located between middle valve body and ceramic valve seat, described spheres of ceramic is positioned at ceramic valve seat, described spheres of ceramic upper end is provided with valve rod hole, and described valve rod is inserted in valve rod hole; It also comprises lower valve shaft, and the bottom of described spheres of ceramic is provided with axis hole, and described lower valve shaft and axis hole plug, and described lower valve shaft is actively socketed in middle valve body and pottery in body.
Described valve rod hole is blind hole.
Described valve rod hole is the step hole that opening end is large, and described valve rod hole opening end is provided with the metal ring matched with it, and described metal ring is located at outside described valve rod.
Described ceramic valve seat is provided with annular groove with the end face that body in pottery matches, and in described annular groove, is provided with seal ring.
Described left valve barrel channel end and right valve barrel channel end are installed with respectively pottery and take over, and described pottery is taken near the ceramic valve seat end and is provided with the two-stage step, and described ceramic valve seat is resisted against on first order step, and step place, the second level is provided with seal ring.
After adopting technique scheme, the utility model is compared with existing background technique, has following advantage:
1, lower valve shaft is set up in the lower end of spheres of ceramic, opens and closes when operation pulling valve rod, and the motion of spheres of ceramic is transmitted stable, and steadiness is good, has guaranteed the safety in utilization of valve.
2, the valve rod hole opening end is provided with metal ring, and metal ring is located at outside valve rod, makes valve rod directly not contact the valve rod hole opening end of spheres of ceramic, and under condition of high voltage, spheres of ceramic is difficult for breaking, and guarantees safety in utilization.
3, ceramic valve seat is provided with seal ring, good sealing effect with the end face that body in pottery matches.
