The function of the gas phase connection valve from the condensate pump inlet pipeline to the surface condenser
Thread Content
There is a gas phase communication line from the inlet pipeline of the condensate pump to the surface condenser (condenser). What is its function? So is the gas phase connection valve on the pipeline normally open or normally closed?
This pipeline is to prevent cavitation in the condensate pump and affect the delivery volume. The valve is a normally open valve, and it should be noted that the pipeline should not have a U-shaped bend to avoid poor exhaust.
The pipeline connecting the inlet of the condensate pump and the condenser is an air balance pipe, which is used for exhaust. Always open.
