Problems solved by technology

At present, for materials with large particles or long lengths, it is not easy to unload when passing through the feed valve, resulting in blockage and blockage of the feed valve, which is not conducive to the continuous operation of the feed valve. After long-term work, it is easy to cause the feed valve to Abrasion, which is not conducive to the maintenance of its airtightness

Abstract

The invention discloses a rotary sealing type feeding valve. The rotary sealing type feeding valve comprises a valve body and a valve element, wherein a feeding opening is formed in the top of the valve body; a discharging opening is formed in the bottom of the valve body; a spherical cavity is formed in the center of the valve body; the valve element is arranged in the spherical cavity and is matched with the spherical cavity; a feeding groove is formed in the valve element; the valve element is connected with a rotating shaft; the other end of the rotating shaft penetrates through the valvebody and then is connected with a driving mechanism; and the driving mechanism drives the rotating shaft and the valve element to rotate. By the feeding valve, the feeding requirement and the sealingrequirement can be met, moreover, large-grained or large-sized materials can be shorn effectively, and retardation and blockage of the feeding valve are avoided.

Description

technical field [0001] The invention relates to a feeding device, in particular to a rotary sealed feeding valve. Background technique [0002] The feed valve is a kind of device that can meet both feeding and sealing requirements. It can effectively prevent the material entering the container from volatilizing outside through the feed port, and is especially suitable for feeding toxic substances. At present, for materials with large particles or long lengths, it is not easy to unload when passing through the feed valve, resulting in blockage and blockage of the feed valve, which is not conducive to the continuous operation of the feed valve. After long-term work, it is easy to cause the feed valve to Wear and tear is not conducive to the maintenance of its airtightness. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention discloses a rotary sealing feed valve, which can meet both feed and sealing requirements,...
