High pressure valve for pneumatically fillable containers - uses e.g. magnets to hold flap valve on seat until complete venting is required

摘要

The high pressure valve closes automatically during pneumatic filling of containers from pressure vessels. The excess pressure after the beginning of the valve opening is reduced almost instantaneously by a largely unimpeded out-flow of the air. The flap opens completely after release from the valve seating, even if a reduction in pressure has already taken place. Magnets are used as a holding or press-on force for the flap on the valve seating.
