Problems solved by technology

[0002] The feed valves used in various dust and particle conveying systems such as thermal power plants, metallurgy, medicine, and chemical industry are usually made of carbon steel. Due to the continuous washing of powder particles, the sealing ring and valve plate are easily worn through. , the sealing performance and wear resistance are poor, and finally the entire feed valve is scrapped, and the service life of the feed valve is short, which not only increases the cost, but also affects the conveying efficiency
If stainless steel is used, the manufacturing cost will be greatly increased
The structure of the traditional feed valve is complicated, and there are often ash stuck and ash, which greatly affects the service life

Abstract

The invention relates to the technical field of a valve device and especially relates to a rotary ceramic feed valve. the rotary ceramic feed valve comprises an upper valve body and a lower valve body which are fixedly sealed and connected, a valve rod is arranged in the lower valve body, the valve rod adjacent to one side of the upper valve body is provided with a valve plate in which a spring connected with the valve plate is embedded; the connection position of the upper valve body and the valve plate is provided with a sealing ring; the outer wall of the upper valve body is provided with a spindle which is connected with the valve rod, the upper half part of the spindle is connected with a swinging arm which is connected with a pneumatic device. The rotary ceramic feed valve is rationally designed, prolonged in service life, and resists wear and heat, thus the feed valve is applied to a thermal power plant, and various dust and granule conveying systems in metallurgy, medicine and chemical engineering, it is low in dust deposition and simply maintained, and has excellent sealing performance and long service life, without jamming.
