Pressure relief valve with rotating damper

摘要

PRESSURE RELIEF VALVE WITH ROTATING DAMPER A combustible gas burner (100) includes gas flow conduit or a housing (102) having an outlet (104) and a pressure relief valve (106). The pressure relief valve (106) includes a valve seat (110) at the outlet (104), a valve body (108) and a valve body rotator (114). The valve body (108) is configured to engage the valve seat (110) and move along an axis (112) relative to the valve seat (110) in response to a pressure at the outlet (104). The valve body rotator (114) is configured to rotate the valve body (108) about the axis (112) in response to movement of the valve body (108) along the axis (112) relative to the valve seat (110).
