Why is the process pipeline cut off?

After filling it with water, after opening the valve for an hour, the water flow became significantly smaller. I would like to ask for professional advice 18804760688
Sir, first of all, after releasing the water for an hour, check whether the water level of the reservoir is still full. If there is an obvious water level difference, it is normal for the downstream water output to become smaller due to the change in water level. If there is no obvious change, it may be that the valve selection has blocked the flow. Valve selection needs to be adjusted.
What I doubt is the sealing of the pipe. If air enters the pipe through the water injection port or other gaps, it will slowly destroy the siphon, causing the water volume to gradually decrease.
The flow rate of the valve opening corresponds to a certain water level difference. It may be that the valve is too open and leaks, and the liquid level pressure difference is reduced.
The water level of the reservoir is very large, and the ground is being irrigated downstream. The water level will drop, so an ordinary check valve is used.
We also tried it, opening the valve one-third, but the flow still stopped.
The check valve is opened and closed by the pressure of the medium. The smaller the flow rate, the smaller the pressure of the medium, and the valve disc will slowly close.
