Are there any check valves that are installed vertically with flow from top to bottom?
This kind of check valve is a valve-type check valve used at the outlet of the compressor, just like the suction and discharge valves on the reciprocating compressor.
The structure must be quite special, please submit the drawings.
It's fine as long as it's not reset by gravity.
Double plates should be fine, axial flow, lifting type
I haven't used it yet. Someone can provide some drawings and we can learn from it.* study * ah!

Reply 1# I have never used Xiaoxiang Yeyu, but I think it should be there. The lift check valve directly on the vertical pipeline is much simpler than the horizontal pipeline.
Yes, I have come into contact with a special valve at the inlet of the jet vacuum pump.
If the check valve is installed this way, it must be spring-return.
Yes, it relies on springs. The valve in my picture relies on spring pressure to check.
