Check valve installed on the intake pipeline of the water ring vacuum pump
Thread Content
The company has one set of exhaust gas absorption equipment, which uses a water ring vacuum pump to draw out the exhaust gases from the system. During shutdowns, water often enters the intake buffer tank. Upon investigation, it was found that the inlet valve was not closed before shutting down, which allowed water to flow back into the buffer tank. Therefore, it is planned to install a check valve; however, after consulting various sources, there is a type of vacuum check valve, and it’s not clear whether this will be effective
Do you recycle the exhaust gas you extract?
I’m not sure how to select a check valve. But you said that installing a check valve is feasible, and the manual for water ring vacuum pumps also recommends installing a check valve.
It should have followed the requirements for a check valve.
We have met and shared our manufacturing process with you; ours features a buffer gas tank, and its storage capacity can be estimated based on the pump’s flow rate. If the gas supply source stops suddenly, the gas holder acts as a buffer, ensuring a continuous flow of gas at the inlet and preventing conditions such as negative pressure or surge, thus allowing for a smooth shutdown. As for the negative pressure condition you mentioned, it’s probably because the air supply is cut off after the outlet is closed, which results in negative pressure, right?
It can be equipped for both import and export operations, or the valves can be automatically closed in a linked manner when the machine is shut down
1. Operationally, it is necessary to drain it in a timely manner. 2. A check valve should be installed
It is more reliable to install a pneumatic ball valve; check valves are not a panacea either.

A pneumatic butterfly valve can be installed to save time and effort. .
1. Establish shutdown procedures; it is best to install automatic shut-off valves. 2. Drain the water when shutting down the system. 3. Control the issue at its source, rather than trying to contain it. 4. Backflow occurs because the negative pressure at the air intake side is not relieved. Shutdown process: XV valve shuts off – FV valve is opened for venting – the liquid ring pump stops working – the buffer tank is drained
