Definitions

  • the invention relates to a tank valve according to the closer defined in the preamble of claim 1. Art Furthermore, the invention relates to the use of such
  • a tank valve for mounting on a pressurized gas container is known from the general state of the art. Such a tank valve is also often referred to by the English term on-tank valve or its abbreviation OTV.
  • the tank valve is a construction with a base body, which has at least two sections, wherein a first body portion protrudes in the assembled state in the compressed gas container and is sealingly connected thereto. Typically, this first body portion is screwed via an external thread into an internal thread of a corresponding receptacle of the compressed gas container. In addition to this in the mounted state within the gas cylinder or its connection thread lying first
  • the body typically has a second
  • Gas cylinder is located.
  • One or typically both of the main body sections now have so-called functional subgroups, which are necessary for the realization of the functionality of the tank valve.
  • Such functional subgroups may be for example a bleed valve, a check valve in a refueling line, a safety valve, a (manual) shut-off valve, a filter, a connection socket for a refueling and / or extraction line or the like.
  • JP 2009-168165 A shows such under the name high-pressure valve.
  • valves are known for example from US 2009/0146094 A1 or in the embodiment as a pilot valve also from EP 1 682 801 B1.
  • a tank valve for example in the field of motor vehicles.
  • the object of the present invention is therefore to avoid the mentioned disadvantage and to provide a safe, reliable and, in particular with regard to the axial extent of the compressed gas tank subsequent axial expansion optimized construction of a tank valve.
  • Claim 10 is also given a particularly preferred use of such a tank valve.
  • the tank valve according to the invention has, similar to the tank valves according to the prior art, a base body in which a plurality of functional sub-groups for refueling the compressed gas storage, for the removal of gas from the compressed gas storage and to implement safety functions are integrated.
  • the main body section protrudes into the interior of the compressed gas container and is in particular via a thread with a corresponding receptacle in the
  • Compressed gas tank in the assembled state sealingly connected to this.
  • Tank valve according to the invention arranged in a single plane of the body. This integration of all functional subgroups in the second
  • Body portion within a single plane allows a very compact construction of the second body portion.
  • This can be designed, for example, when used in a compressed gas container for storing hydrogen at a nominal pressure of 70 MPa so that it has a thickness of only about 25 to 35 mm.
  • a compressed gas container for storing hydrogen at a nominal pressure of 70 MPa so that it has a thickness of only about 25 to 35 mm.
  • the plane is arranged perpendicular to a central axis of the first main body portion and in particular to a central axis of the compressed gas container.
  • the first body portion typically has a central axis which generally coincides with the central axis of the pressurized gas container since the first body portion is typically bolted to a central receptacle of the pressurized gas container.
  • Base body portion having arranged vertically.
  • Magnification of the volume of the gas cylinder can be increased.
  • the functional subgroups are arranged parallel and / or star-shaped in the second basic body section. Within the plane, the functional subgroups are thus arranged parallel and / or star-shaped in the second basic body section.
  • This also allows for the Space in the radial direction, based on a central axis of the plane, a very compact arrangement. This also reduces the space required in this direction and in particular also serves to save weight, since the base body can be realized correspondingly compact and with less material.
  • this arrangement does a very simple and efficient drilling of the recordings for the

  • the base body is made of an aluminum alloy.
  • Tank valve can be integrated in the second body portion at least some of the following functional subgroups:
  • Take-off valve in particular in the form of a pilot valve, which is preferably electromagnetically actuated;
  • Safety valve in particular a thermally triggered safety valve
  • shut-off valve preferably a manually operable shut-off valve
  • Filters in particular inlet filters
  • blow-off connection which in particular can be connected to a line element which serves to remove gas which escapes via the safety valve and / or the drain valve.
  • line element which serves to remove gas which escapes via the safety valve and / or the drain valve.
  • Main body section further functional subgroups are arranged. Further
  • Function subgroups can thus be arranged in addition to the function subgroups in the second basic body section also in the first main body section. There they are in particular parallel to the central axis of the first basic body section and thus perpendicular to the plane in which the functional subgroups in the second

  • the functional subgroups in the first main body section can thereby at least
  • a safety valve in particular a thermally triggered safety valve include.
  • Function subgroups are arranged very protected in the first body portion. Should it happen, for example, as a result of an accident or the like that the second body portion is sheared off from the pressurized gas container with the first base body portion still contained therein, then the pipe element with the pipe rupture protection may be sheared off, however, the pipe rupture protection remains intact.
  • a pipe rupture ensures that in case of breakage or failure of a pipe element this is closed.
  • it can consist of a valve device which acts as a function of a differential pressure between the side facing the interior of the compressed gas container and the other side facing the downstream side of a withdrawal line.
  • the pipe rupture device with a valve body closes the line element and thus prevents the outflow of gas from the compressed gas storage. At the same time is over the check valve in the

  • Fueling pipe, the pipe rupture protection and possibly the rigid diaphragm are in each case securely placed in the first body portion, which is located inside a typically designed via a threaded receptacle of the gas cylinder and will not be affected in the event of damage or only in a very strong damage ,
  • the first main body section can also include the safety valve, which is preferably designed as a thermally triggered safety valve, as one of the functional groups.
  • the safety valve is then of course not, as previously described in a preferred embodiment, arranged in the second body portion.
  • the structure also has the advantage that the second body portion can be realized with even lower height, if it can be dispensed with another fixture, such as the thermally triggered safety valve.
  • the basic body is typically made of a good heat conducting material such as aluminum, in the case of an undesirable heating of the entire body is heated accordingly, so that the thermally triggered safety valve even with an arrangement in the interior of the first
