Scouring-resistant special high-pressure ceramic valve

Abstract

The invention discloses a washing-resistant special high-pressure ceramic valve, and relates to the technical field of high-pressure ceramic valves, the washing-resistant special high-pressure ceramic valve comprises a rotary table, the lower end of the rotary table is fixedly connected with a washing-resistant mechanism, the washing-resistant mechanism comprises a gradual change ring and a washing wheel mechanism, the washing wheel mechanism comprises a wheel sheet mechanism, the wheel sheet mechanism comprises a copper sheet plate, and the copper sheet plate is fixedly connected with the washing wheel mechanism. A connecting mechanism is fixedly connected to one side of the washing-resistant mechanism and comprises a sealing ring mechanism and an inner pipe. Internal high-speed and high-pressure substances impact the wheel sheet mechanism, the hexagonal ring, the oval ring and the two copper sheet plates form a basic frame, rotation is easier, after the high-speed and high-pressure substances enter the flow direction pipe and make contact with the guide groove, rotation of the wheel sheet mechanism is accelerated, the inner wall of the ceramic valve is prevented from being directly scoured, and the service life is prolonged. Centrifugal force generated by rotation of the wheel sheet mechanism, the connecting shaft sleeve and the rotating shaft further counteracts the scouring force, the problem that the scouring force of internal substances is too large is solved, and the effects of weakening the scouring force from multiple angles and improving the wear resistance of the ceramic valve are achieved.

Description

technical field [0001] The invention relates to the technical field of high-pressure ceramic valves, in particular to a special high-pressure ceramic valve that is resistant to erosion. Background technique [0002] Ceramic valve, using high-performance structural ceramics, it has good self-cleaning, super wear-resistant, strong corrosion, strong self-lubrication, long service life, wide use environment, especially suitable for use in chemical industry, in chemical industry, coal, petroleum In such harsh environments, metal valves can no longer meet the needs of harsh working conditions such as high wear and strong corrosion. It is mainly reflected in the situation that metal valves are easy to leak, have large torque, and the sealing surface is not resistant to corrosion. The application of ceramic materials to industrial valves is a A bold and useful innovation. The following problems exist for the prior art: [0003] 1. The ceramic valve of the prior art is widely used ...

AI Technical Summary

Problems solved by technology

[0003] 1. The ceramic valves of the prior art are widely used in some high-pressure, high-wear and strong-corrosion environments. They are in harsh environments for a long time, and the internal high-speed liquid or high-pressure gas easily causes damage to the inner core of the ceramic valve, making it impossible to Normal work, in severe cases, cracks or ruptures in the ceramic valve, resulting in leakage of internal substances;

[0004] 2. Most of the ceramic valves in the prior art use bolts and other installation methods. The installation is slow and the operation process is complicated. For some frequently used parts, too much time is wasted in disassembly and assembly, which prolongs the construction period. The traditional connection There will also be leakage problems during the process, and the sealing is not strong
