Problems solved by technology

[0002] Cone valves have the advantages of high temperature resistance, corrosion resistance, wear resistance, erosion resistance, etc., and are widely used in various acid-base salt gases, liquids, high-temperature steam in chemical industry, metallurgy, papermaking, electric power, medicine, environmental protection and other industries And the slurry conveying system, after a long time of use, the ordinary metal cone valve will wear and tear between the valve core and the middle body to form a gap and cause leakage, so it can only be scrapped, so the metal cone valve has short service life and high cost of use. high problem

Abstract

The invention relates to a rotary cone valve, in particular relates to a ceramic rotary cone valve, and belongs to the technical field of rotary cone valves. The ceramic rotary cone valve comprises a shell, wherein the shell is a metal shell or a ceramic shell, has a split structure or an integrated structure, and is in threaded connection with a flange or a flange pressing ring; an intermediate is arranged in the shell and is made of ceramics or polytetrafluoroethylene; and a ceramic valve core is sleeved in the intermediate in a close fit manner. According to the ceramic rotary cone valve, a clearance between the ceramic valve core and the intermediate can be adjusted, so that an optimal sealing effect is achieved; a ceramic flange liner is in close fit with the flange pressing ring through an additionally arranged step, so that the problem that the ceramic flange liner easily drops off at high temperature in the prior art is solved; the intermediate can be made of a polytetrafluoroethylene material, so that the ceramic rotary cone valve is high in sealing performance, cannot be scratched, is small in torque, and is smoothly turned on and turned off; and with the structure, the ceramic rotary cone valve is long in service life and low in using cost.

Description

Technical field [0001] The invention relates to a spin cone valve, in particular to a ceramic spin cone valve, and belongs to the technical field of spin cone valves. Background technique [0002] The rotary cone valve has the advantages of high temperature resistance, corrosion resistance, abrasion resistance, erosion resistance, etc., and is widely used in various acid-base salt gases, liquids, high-temperature steam in chemical, metallurgy, papermaking, electric power, medicine, environmental protection and other industries And the slurry conveying system, the ordinary metal cone valve will wear out between the valve core and the middle body after a long time, which will cause leakage, which can only be scrapped. Therefore, the metal cone valve has a short service life and a cost of use. High question. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned shortcomings of the prior art and provide a ceramic rotary cone valve with...
