Abstract:
A vent valve flow fuse includes a valve cap with a valve cap cavity defined by one or more valve cap interior surfaces. The vent valve flow fuse includes a valve body with a valve body cavity defined by one or more valve body interior surfaces. The vent valve flow fuse includes a poppet configured to at least partially fit within the valve cap cavity and the valve body cavity. The vent valve flow fuse includes a spring configured to fit within the valve body cavity and to generate a resistive force against the poppet. The poppet is in a first position when fluid having a first amount of fluid pressure enters the valve cap cavity from a vent valve and engages the poppet. The poppet is in a second position when fluid having a second amount of fluid pressure enters the valve cap cavity and engages the poppet.
