Rapid-deflate valve stem cover and associated systems and methods

A rapid-deflate valve cover configured to operably couple to a Schrader valve stem, the rapid-deflate valve cover comprising:

• an annular body defining a central axis and having a proximal end and a distal end, the annular body including:
• a central passage extending through the annular body along the central axis from the proximal end to the distal end;
• a seal positioned within the central passage;
• an exhaust bore proximal to the distal end of the annular body;
• an internally threaded portion positioned within the central passage between the seal and the exhaust bore, the internally threaded portion configured to threadingly engage an externally threaded portion of the Schrader valve stem;
• a pressure relief gap including a longitudinal trough formed in a direction of the central axis along the internally threaded portion;
• and
• a valve core chamber at the proximal end configured to operably receive a valve core within the valve core chamber,
• wherein:
• when the rapid-deflate valve cover is in a closed position, the seal contacts the Schrader valve stem to prohibit gas flow from the Schrader valve stem into the central passage and out of the pressure relief gap, and
• when the rapid-deflate valve cover is in an open position with the internally threaded portion partially threadingly engaged with the externally threaded portion of the Schrader valve stem, the seal is positioned away from the Schrader valve stem to permit gas flow from the Schrader valve stem through the pressure relief gap, and a portion of the exhaust bore extends past the externally threaded portion in a direction along the central axis toward the distal end.
