Tank valve
A tank valve for installation at a pressure gas tank has a base body including a first base body section, which in the assembled state projects into the pressure gas tank and is sealingly connected with the same, and includes a second base body section, which in the assembled state remains outside the pressure gas tank. The tank valve further has a plurality of functional sub-groups for refueling the pressure gas tank via a refueling path, for the extraction of gas from the pressure gas tank via an extraction path, and for implementing safety and operating functions.
1. A tank valve of a pressure gas tank, comprising:
a base body, wherein the base body includes a first base body section which, in an installed state, projects into the pressure gas tank and is sealingly connected with the pressure gas tank and wherein the base body includes a second base body section which, in the installed state, remains outside of the pressure gas tank; and
a plurality of functional sub-groups for refueling the pressure gas tank via a refueling path, for extraction of gas from the pressure gas tank via an extraction path, and for implementing safety and operating functions;
wherein a first subset of the plurality of functional sub-groups is disposed in or on the first base body section;
wherein a first functional sub-group of the first subset is a nonreturn valve in the refueling path;
wherein a second functional sub-group of the first subset is a pipe burst protection in the extraction path.
2. The tank valve according to claim 1 , wherein a third functional sub-group of the first subset is a rigid cover in a line segment leading to or from a safety valve.
3. The tank valve according to claim 2 , wherein a fourth functional sub-group of the first subset is a thermally actuated safety valve.
4. The tank valve according to claim 1 , wherein a second subset of the plurality of functional sub-groups is disposed in the second base body section and wherein all of the functional sub-groups of the second subset are disposed in relation to a respective primary axial alignment and a respective actuation direction within one plane in the second base body section.
5. The tank valve according to claim 4 , wherein the one plane is disposed perpendicular to a central axis of the first base body section.
6. The tank valve according to claim 4 , wherein the second subset includes:
a pilot extraction valve which is magnetically actuatable;
a manually actuatable shut-off valve;
a manually actuatable drain valve;
an inlet filter;
a gas connection; and
a discharge connection.
7. The tank valve according to claim 1 , wherein the base body is an aluminum alloy.
8. The tank valve according to claim 1 , wherein the base body is formed by forging.
9. A use of the tank valve according to claim 1 at the pressure gas tank for storing hydrogen or natural gas as fuel for a nominal pressure of more than 65 MPa in a vehicle.
