Product description
The venting process is smooth and can prevent pressure fluctuations or other destructive phenomena.
-Can discharge the air inside the pipe when the empty pipe is filled with water, and can automatically open when the pipe is emptied or when negative pressure occurs, such as under water column separation conditions, and feed air into the pipe to eliminate negative pressure.
-High-speed discharge of airflow, even mixed with water mist of high-speed airflow will not make the exhaust port closed in advance and lead to air sealing. The exhaust port will only be closed after the air has been completely discharged.
-At any time, as long as the pressure inside the system is lower than atmospheric pressure, such as when the phenomenon of water column separation occurs, the air valve will immediately open to the system air intake, preventing negative pressure in the system. At the same time, when the system is emptying timely air intake can speed up the emptying speed
