[EN] During the filling process in pressurized hydraulic systems, sudden pressure changes generated inside the pipes can cause significant damage. To avoid these excessive overpressures, air valves should be installed to ...
[EN] The present paper summarizes the results obtained in air release and admission tests in air valves with diameter between 50 and 150 mm. The pressure-flow curves are presented and the pressure values at which dynamic ...
[ES] En este trabajo se propone y describe un método para la obtención experimental de las
curvas que relacionan la presión en el interior de la tubería con el caudal másico expulsado o
admitido por ventosas. El método de ...
[EN] Air pockets generated during emptying operations in pressurized hydraulic systems cause
significant pressure drops inside pipes. To avoid these sudden pressure changes, one of the most
widely used methods involves the ...
