NOISE REDUCTION RELIEF VALVE FOR CRYOGENIC LIQUID CONTAINERS

摘要

A relief valve coupled to a container is disclosed. The relief valve may include a valve body forming an internal chamber, an inlet portion connected to the chamber and configured to receive content flow from the container, a spring, a poppet including a seat disc, wherein a spring force exerted by the spring biases the seat disc towards the inlet portion, and a cap configured to include a plurality of passages.

主权项

1. A relief valve configured to be coupled to a relief outlet of a cryogenic container, the relief valve comprising:
a valve body forming an internal chamber and having a central axis, a proximal end and a distal end; an inlet portion located at the proximal end of the valve body and configured to be connected to the internal chamber and to receive content flow from the container, wherein fluid entering the internal chamber from the inlet portion travels in the general direction of the central axis; a spring and a moveable poppet disposed in the internal chamber, wherein a spring force exerted by the spring biases the poppet towards the inlet portion; and a cap configured to be connected to the distal end of the valve body, the cap comprising a plurality of passages for fluid flow, wherein each of the plurality of passages has a separate passage axis that is generally perpendicular to the central axis.
