摘要:
The invention relates to a valve, a container with the valve and the use of the valve. The valve, which is useful in a container to prevent an excessive pressure difference between the outside of the container and the inside of the container, comprises two blocking elements (1, 2; 110, 114), one of which (1; 110) allows fluid to enter the container when the external pressure exceeds the internal pressure by a predetermined magnitude, and the other of which (2; 114) allows fluid to enter the container when the internal pressure exceeds the external pressure by a predetermined magnitude.
摘要:
The present invention concerns those elements that, by means of valves, allow the balance of forces acting upon the walls of a hermetic container during its sinking in a liquid, thus preventing the stress produced due to the effect from an increased volume of liquid applied on the external face of the container. It also prevents spillage of the content into the surrounding environment through the said elements and is provided with the means to equally balance the forces cited during eventual re-floatation of the aforementioned container.
