What type of valve is used to cut off the pipeline conveying powder? The working temperature is 150 degrees Celsius, the outlet side is in the atmosphere, and the inlet side is in a negative pressure environment. The material will turn into metal sheets when rolled, which will affect the subsequent process. It is not suitable for metal hard sealing. Can you provide selections?
Inlet negative pressure and outlet atmosphere. Are you sure it can flow?
This post was last edited by CHANGBAISHI on 2020-3-31 08:45 to see if this should be possible, but whether it is feasible to have strict sealing requirements. Haha, for the sake of convenience, I will do a voluntary publicity for his family;P https://item.taobao.com/item.htm?spm=a230r.1.14.87.5719684ehpkNcy&id=552910591881&ns=1&abbucket=17#detail Browse down for product introductions to see if they are suitable for you, for reference.
If it is negative pressure, it may be difficult to unload materials, or it may affect the negative pressure process conditions in the tank. If it doesn't matter, it's the best choice.
Is it metal powder? How about using a hose valve, or a flapper valve?
It should be discharged by its own weight or a rotary valve.
It can flow. The specific gravity of the medium is large. The negative pressure is caused by the fan. The static pressure can overcome the atmospheric pressure.
The flapper valve does not seal well. I am also using it here. Is the hose valve a pinch valve? The inner tank of the pipe pinch valve I used has a short lifespan. The inner tank was damaged after being opened and closed 1500 times. I wonder if there is a problem with the manufacturing quality.
It can be opened and closed 1500 times, which is still relatively good. If it breaks, just replace it.
