Method and apparatus for functional testing of containers, especially tank venting devices

摘要

The method of functional testing of vessels, especially tank vents, is improved by using as few additional devices as possible to accurately specify the presence of leakage in the vessel and to allow for "accurate" reference measurements.;It is coupled to the tank 10, the adsorption filter 20 which is coupled to the tank 10 via the connection piping 12, and has the ventilation pipe 22, and is connected to the adsorption filter 20 via the valve piping 24, A tank vent valve 30 in which the pressure is applied in the vessel by a pressure source and the presence of leakage from the pressure process and / or the supplied volume flow rate is specified, in particular a method of functional testing of the tank vent device. And in the apparatus, the operating characteristic of the pressure source is measured when applying pressure to determine the pressure process and / or the volumetric flow rate supplied, from which the presence of a leak is specified.
