A safety arrangement for a DME fuel tank of a vehicle, adapted to release an excessive pressure from the fuel tank, including a spring-loaded pressure release valve adapted to open at a predefined pressure level, where the safety arrangement further includes a housing mounted on the fuel tank and having an outer opening closed by a lid, where the pressure release valve is arranged in the housing and where the housing is provided with an outlet pipe having an outlet opening, and where the lid is adapted to melt at a predefined temperature, thereby allowing gas to exit the pressure release valve through the outer opening of the housing when the pressure release valve is open and the lid has melted. A small gas leakage caused by an excessive pressure can be discharged downwards through the outlet pipe and outlet opening towards the ground, and a large gas leakage, caused by e.g. a fire, can be discharged outwards from the fuel tank, away from the fire.
A safety arrangement for a liquefied gas fuel tank of a vehicle, adapted to release an excessive pressure from the fuel tank, comprising a pressure release valve adapted to open at a predefined pressure level, wherein the safety arrangement further comprises a housing mounted on the fuel tank and having an outer opening closed by a lid, where the pressure release valve is arranged in the housing and where the housing is provided with an outlet pipe having an outlet opening, and where the lid is adapted to melt at a predefined temperature, thereby allowing gas to exit the pressure release valve through the outer opening of the housing when the pressure release valve is open and the lid has melted, wherein the lid is attached to the housing with screws.
A safety arrangement for a liquefied gas fuel tank of a vehicle, adapted to release an excessive pressure from the fuel tank, comprising a pressure release valve adapted to open at a predefined pressure level, wherein the safety arrangement, further comprises a housing mounted on the fuel tank and having an outer opening closed by a lid, where the pressure release valve is arranged in the housing and where the housing is provided with an outlet pipe having an outlet opening, and where the lid is adapted to melt at a predefined temperature, thereby allowing gas to exit the pressure release valve through the outer opening of the housing when the pressure release valve is open and the lid has melted, wherein the safety arrangement is provided with a sealing ring between the lid and the housing.
A safety arrangement for a liquefied gas fuel tank of a vehicle, the liquefied gas fuel tank having a first end and an opposing second end, an axis of the liquefied gas fuel tank extending between the first end and the second end, the safety arrangement being adapted to release an excessive pressure from the liquefied gas fuel tank, comprising a pressure release valve adapted to open at a predefined pressure level, wherein the safety arrangement further comprises a housing mounted on the liquefied gas fuel tank and having an outer opening closed by a lid, where the pressure release valve is arranged in the housing and where the housing is provided with an outlet pipe having an outlet opening, and where the lid is adapted to melt at a predefined temperature, thereby allowing gas to exit the pressure release valve through the outer opening of the housing when the pressure release valve is open and the lid has melted for jetting the gas out radially relative to the axis of the liquefied gas fuel tank.
