Definitions
- Valve assembly for a fuel gas tank for a fuel gas tank, fuel gas tank with valve assembly
- the invention relates to a valve assembly for a fuel gas tank.
- the invention also relates to a fuel gas tank with a valve assembly according to the invention.
- the fuel gas can in particular be hydrogen or natural gas, which is stored under pressure in a fuel gas tank.
- the preferred field of application of the invention is fuel cell and/or gas vehicles that are powered by a fuel gas.
- the fuel gas tank is usually designed as a high-pressure tank, in particular as a high-pressure gas bottle.
- a high-pressure tank always requires a shut-off valve to seal the tank tightly when the vehicle is not in use.
- the shut-off valve is usually designed as a valve that is closed when there is no current.
- the shut-off valve is usually integrated into a valve assembly that allows both the extraction of fuel gas from the fuel gas tank and the filling of the fuel gas tank with fuel gas.
- the valve assembly has a base body in which a extraction path and a filling path are formed.
- a controllable shut-off valve is integrated into the extraction path and a check valve is integrated into the filling path.
- the check valve prevents fuel gas from escaping from the fuel gas tank via the filling path.
- a further check valve can be arranged in the extraction path so that the flow direction in the two paths is determined via the check valves.
- DE 10 2016 008 443 A1 provides an example of a tank valve for mounting on a compressed gas container, which has a base body with a gas connection, via which the compressed gas container can be filled on the one hand and gas can be removed from the compressed gas container on the other.
- the gas connection is divided into a refueling line and a withdrawal line, with a withdrawal valve arranged in the withdrawal line.
- a check valve connected in series with the withdrawal valve blocks the flow against the intended flow direction when gas is withdrawn. The check valve thus prevents gas from flowing into the compressed gas container via the withdrawal line during refueling.
- Another check valve is integrated in the refueling line, which opens in the refueling direction and closes in the withdrawal direction.
- the present invention is concerned with the object of specifying a valve assembly for a fuel gas tank which, for example, allows emergency refueling of the fuel gas tank via the removal path if the refueling path is blocked or the check valve in the refueling path is jammed.
- valve assembly with the features of claim 1 is proposed.
- Advantageous further developments of the invention can be found in the subclaims.
- a fuel gas tank with a valve assembly according to the invention is specified.
- the valve assembly proposed for a fuel gas tank comprises a base body in which a removal path with an integrated shut-off valve for removing fuel gas from the fuel gas tank and a refueling path with an integrated check valve for refueling the fuel gas tank with fuel gas are formed, wherein the removal path and the refueling path are combined within the base body in a path that opens into a common gas connection.
- at least two further gas flow paths are formed in the base body, each of which bypasses the shut-off valve and forms a downstream section of the removal path arranged downstream of the shut-off valve in the removal direction.
- an inflow-side section of the extraction path arranged upstream of the shut-off valve and/or with a storage volume formed in the fuel gas tank.
- the flow direction in the extraction path is determined by a first check valve arranged in the inflow-side section and a second check valve arranged in the outflow-side section, and the flow through the two further gas flow paths in the extraction direction is blocked by a check valve each.
- the two additional gas flow paths together with the shut-off valve, form an emergency refueling path that can be used to refuel the fuel gas tank in the event of a malfunction in the actual refueling path. All that is required is to actively open the shut-off valve.
- the refueling pressure then opens the check valves arranged in the two additional gas flow paths, so that the fuel gas tank is refueled via the two additional gas flow paths and the open shut-off valve.
- the two check valves integrated into the extraction path ensure that the shut-off valve can only be flowed through in the forward direction and therefore only when it is activated. This means that the shut-off valve cannot open accidentally during a normal refueling process.
- a first gas flow path branches off from the extraction path upstream of the check valve integrated into the downstream section of the extraction path and flows into the extraction path or directly into the storage volume of the fuel gas tank upstream of the check valve integrated into the upstream section of the extraction path.
- Pressure relief can thus be achieved via the first gas flow path, which ensures that the pressure on the downstream side of the shut-off valve is never greater than the pressure in the fuel gas tank.
- the first gas flow path can therefore be referred to as a pressure relief path.
- the shut-off valve can be bypassed via the pressure relief path in order to connect the downstream side with the upstream side or with the storage volume of the fuel gas tank.
- a second gas flow path preferably branches off from the extraction path downstream of the check valve integrated in the downstream section of the extraction path and opens downstream of the check valve integrated in the upstream section of the extraction path integrated check valve - on the inflow side of the shut-off valve - into the extraction path.
- Pressure equalization can be achieved via the second gas flow path, which ensures that the pressure on the inflow side of the shut-off valve is never lower than the pressure in the area of the gas connection.
- the component can have two valve closing elements, between which a spring is arranged, by which each valve closing element is pre-tensioned in the direction of a valve seat.
- the component can be connected to the inflow side of the shut-off valve via the space between the two valve closing elements that accommodates the spring.
- the component can have a one-piece valve closing element with a circumferential groove and longitudinal grooves that can be moved back and forth between two valve seats.
- the component can be connected to the inflow side of the shut-off valve via the circumferential groove.
- the longitudinal grooves connect the circumferential groove with the gas volumes at the valve seats.
- the valve element is moved purely pneumatically into either one or the other end position, so that one valve seat is open and the other closed. Both valve seats are never open or closed at the same time.
- the opening and closing of the check valves can therefore be achieved purely pneumatically. This means that a spring is not required.
- the shut-off valve is preferably electrically controlled and/or designed as a normally closed valve.
- the shut-off valve can be designed to be particularly compact and robust.
- the shut-off valve can be actively opened to remove fuel gas from the fuel gas tank or to carry out emergency refueling.
- the common gas connection is designed as a connecting piece, preferably as a connecting piece with an external thread.
- the connecting piece facilitates the connection of an external gas line, via which fuel gas can be taken from the fuel gas tank and fuel gas can be supplied to the fuel gas tank when refueling. If the connecting piece has an external thread, the external gas line can be screwed onto the connecting piece, so that a high-pressure-resistant connection is established between the gas line and the valve assembly via the screw connection.
- the base body preferably has a connecting section for connection to the fuel gas tank.
- the valve assembly can be easily mounted on a fuel gas tank via the connecting section.
- the valve assembly can be inserted into a bottle neck of a fuel gas tank designed as a high-pressure gas bottle via the connecting section.
- the connecting section can also have an external thread so that it can be screwed into the bottle neck in order to achieve a high-pressure-resistant connection via the screw connection.
- the fuel gas tank also proposed is characterized in that it has a valve assembly according to the invention.
- the valve assembly is preferably inserted into the fuel gas tank in sections so that the common gas connection is accessible from the outside. Since the extraction path and the refueling path are brought together and lead as one path into the common gas connection of the valve assembly, only one gas line needs to be connected for extracting fuel gas and for refueling the fuel gas tank with fuel gas.
- Fig. 1 is a schematic representation of a valve assembly according to the invention inserted into a fuel gas tank with arrows to show the gas flow directions when removing fuel gas from the fuel gas tank and during regular refueling of the fuel gas tank with fuel gas
- Fig. 2 is a schematic representation of a further valve assembly according to the invention inserted into a fuel gas tank with arrows to show the gas flow directions when removing fuel gas from the fuel gas tank and during regular refueling of the fuel gas tank with fuel gas
- Fig. 2 is a schematic representation of a further valve assembly according to the invention inserted into a fuel gas tank with arrows to show the gas flow directions when removing fuel gas from the fuel gas tank and during regular refueling of the fuel gas tank with fuel gas
- Fig. 3 is a schematic representation of the valve assembly of Figure 2 with an arrow to show the gas flow direction during emergency refueling of the fuel gas tank via the actively opened shut-off valve,
- Fig. 4 shows a longitudinal section through two check valves opening in opposite directions, which are combined to form a component with two valve closing elements, whereby a spring arranged between the two valve closing elements applies a closing force to both valve closing elements in the direction of a valve seat,
- Fig. 5 is a longitudinal section through two check valves opening in opposite directions, which are combined to form a component with a one-piece valve closing element,
- Fig. 6 a cross section through the component of Figure 5 and
- the valve assembly 1 according to the invention shown in Figure 1 serves to remove fuel gas from a fuel gas tank 2 and to fill the fuel gas tank 2 with fuel gas, in particular with hydrogen or with natural gas.
- the valve assembly 1 shown has a base body 3 with a connecting section 16, via which the valve assembly 1 is connected to the fuel gas tank 2. At the other end, the base body 3 forms a gas connection 8 for the connection of an external gas line (not shown). In order to connect only one gas line must, a removal path 4 formed in the base body 3 and a refueling path 5 formed in the base body 3 are combined to form a path 9 which opens into the gas connection 8.
- a shut-off valve 6 is integrated into the extraction path 4, which can be controlled electrically and is designed as a normally closed valve.
- a first check valve 12 is arranged, which opens in the extraction direction.
- a second check valve 13 is arranged, which also opens in the extraction direction.
- the extraction path 4 thus leads via an inflow-side first section 4.1, in which the check valve 12 is integrated, the shut-off valve 6 and a downflow-side second section 4.2, in which the check valve 13 is integrated.
- the downstream section 4.2 is connected to the upstream section 4.1 via two further gas flow paths 10, 11, bypassing the shut-off valve 6.
- a check valve 14, 15 is arranged in each of these gas flow paths 10, 11 in such a way that it blocks in the removal direction.
- the first gas flow path 10 branches off in the extraction direction (arrow 18) upstream of the check valve 13 from the downstream section 4.2 of the extraction path 4 and flows upstream of the check valve 12 into the upstream section 4.1 of the extraction path 4. Via the first gas flow path 10, pressure relief in the direction of the fuel gas tank 2 (see arrow 27) can be ensured, which prevents the pressure p ou t on the downstream side of the shut-off valve 6 from rising above the pressure pi in the fuel gas tank 2.
- the second gas flow path 11 branches off in the extraction direction (arrow 18) downstream of the check valve 13 and downstream of the shut-off valve 6 from the downstream section 4.2 of the extraction path 4 and flows downstream of the check valve 12 and upstream of the shut-off valve 6 into the inflow section 4.1 of the extraction path 4.
- a pressure equalization can be effected in the direction of the inflow side (arrow 28) of the shut-off valve 6, which prevents the inflow-side pressure pi n at the shut-off valve 6 from falling below the pressure P2 at the gas connection 8.
- the check valve 12 ensures that the pressure pi n on the inflow side of the shut-off valve 6 does not fall below the pressure pi in the fuel gas tank 2 and at the same time the check valve 13 ensures that the pressure p ou t on the outflow side of the shut-off valve 6 does not rise above the pressure P2 at the gas connection 8, it is certain that the pressure p ou t on the outflow side of the shut-off valve 6 never exceeds the pressure pi n on the inflow side of the shut-off valve 6. This prevents the shut-off valve 6 from opening unintentionally and/or flowing through in the reverse direction.
- Another check valve 7 is integrated into the refueling path 5, which opens in the refueling direction (arrow 17) when the pressure P2 in the area of the gas connection 8 is greater than the pressure pi in the fuel gas tank 2. If the refueling path 5 is blocked, emergency refueling can be carried out via the two gas flow paths 10, 11 and the section of the extraction path 4 leading via the shut-off valve 6 by actively opening the shut-off valve 6.
- Figures 2 and 3 show a further preferred embodiment of a valve assembly 1 according to the invention.
- a bore intersection can be dispensed with, so that the high-pressure resistance of the valve assembly 1 is increased.
- arrow 17 indicates the refueling direction in which the fuel gas flows into the fuel gas tank 2 via the refueling path 5 when refueling the fuel gas tank 2.
- Arrow 18 indicates the removal direction in which the fuel gas flows when removing fuel gas from the fuel gas tank 2.
- Arrows 27 and 28 in turn indicate the gas flow direction in the other gas flow paths 10, 11 to achieve pressure relief or pressure equalization.
- the gas flow direction during emergency refueling of the fuel gas tank 2 via the actively opened shut-off valve 6 and the gas flow paths 10, 11 is indicated by an arrow 19.
- valve assembly 1 In order to create a valve assembly 1 that is as compact as possible, the two check valves 12 and 15, which open in opposite directions and are connected via their respective downstream sides, can be combined to form a component 20. Possible embodiments are shown in Figures 4 to 7.
- FIG. 4 A first preferred embodiment of a component 20 is shown in Figure 4.
- the component 20 has two valve closing elements 23.1, 23.2, wherein each valve closing element 23.1, 23.2 is prestressed in the direction of an associated valve seat 21, 22 via an intermediate, common spring 24.
- the spring 24 is accommodated in a valve chamber 29, which connects the component 20 to the inflow side of the shut-off valve 6 or to the inflow-side section 4.1 of the extraction path 4.
- the check valve 12 opens against the spring force of the spring 24, while the valve closing element 23.2 is pressed against the valve seat 22 and closes the check valve 15.
- the check valve 15 opens with the valve closing element 23.2 against the spring force of the spring 24, while the valve closing element 23.1 is pressed against the valve seat 21 and closes the check valve 12.
- valve closing element 23 is designed in one piece and is controlled solely by pressure, i.e. pneumatically, so that a spring 24 is not required.
- the valve closing element 23 has a circumferential groove 25, via which the valve chamber 29 is connected to the inflow side of the shut-off valve 6 or to the inflow-side section 4.1 of the extraction path 4.
- valve closing element 23 Since the valve closing element 23 is guided radially, it also has at least one longitudinal groove 26 on each side of the circumferential groove 25, which opens into the circumferential groove 25 and serves as a gas flow channel (see Figure 6).
- the valve seat 21 When the valve seat 21 is open, the gas flows from there via the at least one longitudinal groove 26 between the circumferential groove 25 and the end of the guide of the valve closing element 23 facing the valve seat 21 to the valve chamber 29.
- valve seat 22 When the valve seat 22 is open, the gas flows from there via the at least one longitudinal groove 26 between the circumferential groove 25 and the end of the guide of the valve closing element 23 facing the valve seat 22 to the valve chamber 29.
- Figure 5 shows the valve closing element 23 in a switching position which it assumes when P2 > pi. Pressure equalization can then be achieved via the open check valve 15, which prevents the shut-off valve 6 from opening accidentally. During emergency refueling, the valve closing element 23 also assumes the switching position shown in Figure 5. The check valve 12 is closed in this switching position.
- Figure 7 shows the valve closing element 23 in a switching position which it assumes when P2 ⁇ pi and the shut-off valve 6 is actively opened. Fuel gas can then be removed from the fuel gas tank 2 and led to the gas connection 8 via the open check valve 12, the open shut-off valve 6 and the also open check valve 13. The check valve 15 is closed in this switching position.
- a valve assembly according to the invention can have additional valves and/or components in addition to the valves shown.
- a manual shut-off and/or blow-off valve, a thermal and/or pressure-controlled safety valve and a temperature and/or pressure sensor can be integrated into the valve assembly.
