摘要： The present invention relates broadly to a pressure relief valve and vent assembly (10) comprising a pressure relief valve (12) arranged to couple to a tank (14), and a tank vent (26). The tank vent (26) comprises a vent body (16) having a vent inlet (18) and a exhaust outlet (20) in communication with each other via a fluid passageway (22). The tank vent also comprises an exhaust check valve (24) connected to the vent body (16) at the exhaust outlet (20). The exhaust check valve (24) is arranged to allow fluid to flow through the fluid passageway (22) in one direction only from the tank (14) to atmosphere via the vent inlet (18) and the exhaust outlet (20). the pressure relief valve and vent assembly (10) also includes an ambient air inlet (28) in fluid communication with the fluid passageway (22). The ambient air inlet (28) is arranged to permit the flow of ambient air from atmosphere into the tank (14) via the vent inlet (18). The tank vent (26) also comprises an ambient air inlet check valve (30) configured to allow air flow in one direction only from atmosphere to the tank (14) via the air inlet (28).

摘要： A pressure relief valve and vent assembly include a tank vent including: (i) a vent body having a vent inlet adapted to connect to a tank and arranged to communicate with an exhaust outlet via a fluid passageway; (ii) an exhaust check valve connected to the vent body at or adjacent the exhaust outlet, the exhaust check valve being configured to allow flow in one direction only; and (iii) a pressure relief valve connected to the tank vent inlet and adapted to couple to a tank. The pressure relief valve, when closed, allows for venting air or air/hydrocarbon mixtures from the tank to the exhaust check valve via the fluid passageway. The pressure relief valve, when opened on pressurization of the tank, exhausts tank fluid from the exhaust check valve.
