Problems solved by technology

When the pressure fluctuations on both sides of the valve body of this kind of pneumatic loop sealing valve are large, material gushing phenomenon often occurs, so it is difficult to effectively control the feeding amount and discharging amount, and it is difficult to meet the production needs
In addition, for valves that work in a high-temperature aerobic atmosphere above 1400 °C, the selection of materials and structures is also a major problem at present.
Because it has not yet found a material that can withstand extremely high temperature oxidation above 1400°C, has extremely high temperature strength and wear resistance without brittleness, and a loop seal valve made of it

Abstract

The invention belongs to the technical field of chemical engineering and particularly relates to an extremely high temperature resistant and adjustable pneumatic loop sealing valve device. According to the extremely high temperature resistant and adjustable pneumatic loop sealing valve device, a high-temperature resistant thermal insulation layer is arranged on the casing inner wall in a lining manner; a high-temperature resistant lining is built in the wall body; a feed opening is formed in the left side at the top of the casing; a discharge opening is formed in the right side at the bottom of the casing; an extremely high temperature resistant rotating valve body is fixedly mounted on the wall between curved passages connecting the feed opening with the discharge opening; a tungsten rod shaft and a U-shaped tungsten plate are adopted as a frame; then corundum casting materials are adopted to cast the frame into the rotating valve body which satisfies the valve size requirement; the left end of the tungsten rod shaft extends out of the casing and is fixedly connected with a driving sleeve shaft of an electric actuator. Through the adoption of the extremely high temperature resistant and adjustable pneumatic loop sealing valve device, the material flushing phenomenon is effectively prevented and the working requirement for valves in extremely high temperature aerobic atmosphere is satisfied.

Description

technical field [0001] The invention belongs to the technical field of chemical engineering, and in particular relates to an extremely high temperature-resistant adjustable pneumatic loop sealing valve device. Background technique [0002] There is a pneumatic loop sealing valve in the existing fluidized production equipment, and the pneumatic loop sealing valve is both a feeding device and a discharging device in use. When the pressure fluctuations on both sides of the valve body of this kind of pneumatic loop sealing valve are large, material gushing phenomenon often occurs, so it is difficult to effectively control the feeding amount and discharging amount, and it is difficult to meet the production needs. In addition, the selection of materials and structures for valves working in a high-temperature aerobic atmosphere above 1400°C is also a major problem at present. Because there is no material that can withstand extremely high temperature oxidation above 1400° C., has ...
