Sealed valve for isolating solids
Thread Content
This post was last edited by Qingchengjun on 2023-2-16 at 10:13. In industry, when solid materials need to be added to a sealed container that contains flammable, explosive, or toxic gases, this addition is carried out without removing the gases from the container first. First, add the solid material to a silo by feeding it openly, and after the feeding is complete, seal the feeding port. Open the isolation valve to introduce the solid, then close the isolation valve. Are there any valves that offer good sealing, durability, and easy material guidance?
A ball valve is selected. You can refer to the ball valve animation; it’s very concise and clear, lasting about 15 seconds. Please download from https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=989003&shareuid=301199

Thank you. I haven’t been able to view the video due to computer issues; I’m not yet clear about the differences between track ball valves and ordinary ball valves. It’s inevitable that there will be small particles left behind in solids, and without the possibility of washing them with water, I’m concerned that the ball itself may wear out quickly
You can refer to the thread asking for recommendations on manufacturers of imported ball valves for continuous reforming and regeneration systems: https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1467119&shareuid=301199. These ball valves can serve as a reference for your application requirements.
If the container contains pressurized flammable, explosive, or toxic gases, a hopper system should be used for solid feeding.
Powder ball valves are available; a lock-hopper system is preferable, with nitrogen used for pressurized purging and displacement
Search for ball valves specifically designed for powders; those produced in places like Ruian, Zhejiang are also good options
