Abstract

See full text

A pressure relief valve includes a valve seat at the outlet, a valve body, and an air dashpot damper. In some embodiments, the valve body is configured to engage the valve seat and move along a central axis relative to the valve seat in response to a pressure at the outlet to regulate a flow of combustible gas through the outlet. In some embodiments, the air dashpot damper includes a tubular member having a closed distal end and an open proximal end, and a piston member received within the tubular member. In some embodiments, the tubular member or the piston member is attached to the valve body, and the piston moves relative to the tubular member along an axis of the tubular member in response to movement of the valve body relative to the valve seat. In some embodiments, the pressure relief valve includes a plurality of the air dashpot dampers.
