Novel rotary valve

Abstract

The invention discloses a novel rotary valve. The novel rotary valve mainly solves the problem that exiting gas pipeline control valves are blocked due to too much tar and the problem that existing waste gas pipeline control valves cannot be opened so as to be blocked due to too much accumulated dust. The novel rotary valve comprises a valve body, a valve element, an inlet, an outlet and a valve shaft. The novel rotary valve is a multifunctional valve not only capable of achieving quantitative control but also capable of achieving variable control. The blockage phenomenon is avoided, sealing performance is good, and no blockage phenomenon appears at high temperature.

Description

technical field [0001] The invention relates to a novel rotary valve, which belongs to the technical field of valve production. Background technique [0002] Most of the existing gas pipelines or waste gas pipelines use butterfly valves for adjustment and control. But after using for a period of time, it is difficult to open the valve due to tar or dust blockage, and it is difficult to close tightly after opening. [0003] The finished product silo of the vertical kiln is controlled by a traditional plug-in board at the outlet. This manual plug-in board is usually fixed and cannot be adjusted to achieve uniform feeding of the material in the bin. During production, the material in the silo is freely fed by the drop. As the material level in the silo decreases to a certain level, the material against the wall of the silo will suddenly collapse, causing the material to pass through and crush the sieve in the next process to death. , In addition, when the material slide is to...

Problems solved by technology

But after using it for a period of time, it is difficult to open the valve due to tar or dust blockage, and it is difficult to close it tightly after opening.

[0003] The finished product silo of the vertical kiln is controlled by a traditional plug-in board at the outlet. This kind of manual plug-in board is usually fixed, and the material in the bin cannot be adjusted to achieve uniform feeding.

During production, the material in the silo is freely fed by the drop. As the material level in the silo decreases to a certain level, the material against the wall of the silo will suddenly collapse, causing the material to pass through and crush the sieve in the next process to death. In addition, when the material slide is too large, it can also block the crushing ring hammer in the next process of the sieve

In addition, the star-shaped ash discharge valve of the terminal ash storage bin of the dust collector is too slow to discharge ash, and variable control cannot be implemented
