Abstract
The utility model relates to rotary cone valves, in particular to a ceramic rotary cone valve and belongs to the technical field of the rotary cone valves. The ceramic rotary cone valve comprises a shell body, wherein the shell body is made of metal or ceramic, the shell body is of a split-type structure or an integrated structure, and the shell body is connected with a flange or a flange compression ring in a threaded mode. A middle body is arranged in the shell body, wherein the middle body is made of ceramic or polytetrafluoroethylene, and a ceramic valve core is tightly sleeved inside the middle body in a matched mode. According to the ceramic rotary cone valve, a gap between the ceramic vale core and the middle body can be adjusted, and therefore the best sealing effect can be achieved. A ceramic flange lining is closely matched with the flange compression ring through a step which is additionally arranged, and therefore the problem that a ceramic flange lining is prone to disengaging at the high temperature in the prior art is solved. In addition, due to the fact that the middle body can be made of polytetrafluoroethylene, the sealing performance of the ceramic rotary cone valve can be better, scratch will not be generated, the torque will not be small and opening and closing can be smooth. According to the structure, the ceramic rotary cone valve is longer in service life and lower in usage cost.
