Abstract
A tank valve with a valve seat and a valve disc can be displaced relative to the valve seat along a displacement direction into either a closed position or a through-flow position. The valve seat includes a plate shaped part and a ring-shaped part. The valve disc has a first contact area which contacts the first plate shaped part of the valve seat when the tank valve is in the closed position. The valve disc also has a second contact area which is in contact with a second part of the valve seat when it is in the closed position.
Claims14
A tank valve, comprising:
- a valve seat comprising a first part that is plate-shaped, and a second part that is ring-shaped;
- and
- a valve disc displaceable relative to the valve seat along a displacement direction to either a closed position where the tank valve is closed or to a through-flow position where the tank valve is open, wherein the valve disc is configured to be displaceable to the closed position by a force from hydrostatic pressure pushing on the valve disc;
- wherein the valve disc comprises a first contact area which is in contact with the first part of the valve seat when the tank valve is in in the closed position,
- wherein the valve disc comprises a second contact area which is in contact with the second part of the valve seat when the tank valve is in the closed position, and
- wherein the first part of the valve seat is positioned above the second part of the valve seat.
A tank for liquefied gases, comprising:
- at least one tank volume;
- a tank valve situated inside the tank volume, wherein the tank valve comprises
- a valve seat comprising a first part that is plate-shaped, and a second part that is ring-shaped;
- and
- a valve disc displaceable relative to the valve seat along a displacement direction to either a closed position where the tank valve is closed or to a through-flow position where the tank valve is open, wherein the valve disc is configured to be displaceable to the closed position by a force from hydrostatic pressure pushing on the valve disc;
- wherein the valve disc comprises a first contact area which is in contact with the first part of the valve seat when the tank valve is in in the closed position,
- wherein the valve disc comprises a second contact area which is in contact with the second part of the valve seat when the tank valve is in the closed position, and
- wherein the first part of the valve seat is positioned above the second part of the valve seat.
A tank valve, comprising:
- a valve seat comprising a first part that is plate-shaped, and a second part that is ring-shaped;
- and
- a valve disc displaceable relative to the valve seat along a displacement direction to either a closed position where the tank valve is closed or to a through-flow position where the tank valve is open, wherein the valve disc is configured to be displaceable to the closed position by a force from hydrostatic pressure pushing on the valve disc in an absence of a traction force;
- wherein the valve disc comprises a first contact area which is in contact with the first part of the valve seat when the tank valve is in in the closed position,
- wherein the valve disc comprises a second contact area which is in contact with the second part of the valve seat when the tank valve is in the closed position, and
- wherein the first part of the valve seat is positioned above the second part of the valve seat.
