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valve connected in series with the withdrawal valve blocks the flow against the intended flow direction when gas is withdrawn.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 task of specifying a valve assembly with an integrated shut-off valve for removing fuel gas from a fuel gas tank, in which an unintentional opening of the shut-off valve is reliably prevented. Furthermore, with the help of the shut-off valve, the valve assembly should be able to be used for refueling the fuel gas tank.
- 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 withdrawal path with an integrated shut-off valve for withdrawing 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.
- the withdrawal path and the refueling path are combined within the base body in a path that opens into a common gas connection.
- a pressure equalization path branches off from this path or from an end face of the common gas connection, which is located upstream of the shut-off valve in the withdrawal direction. tils into the extraction path.
- a check valve is integrated into the pressure equalization path, which blocks in the extraction direction.
- the pressure equalization path with integrated check valve ensures that - regardless of the pressure in the fuel gas tank and regardless of the pressure in the area of the gas connection - the higher pressure of the two is always present on the inflow side of the shut-off valve.
- the pressure that prevails in the area of the gas connection is always present.
- the pressure on the inflow side is therefore always greater than or equal to the pressure on the outflow side. This means that there is never a differential pressure at the shut-off valve that would cause the shut-off valve to open unintentionally. This ensures that flow only passes through the shut-off valve in the direction of extraction and not in the opposite direction.
- it is therefore ensured that no fuel gas contaminated with water gets into the shut-off valve, freezes at low outside temperatures and blocks the shut-off valve.
- Another advantage is that a small gas flow only flows briefly through the pressure equalization path to achieve the desired pressure equalization. This means that the pressure equalization path and the check valve integrated in it can be designed for low flow rates. The additional path and the additional check valve therefore require little installation space.
- a check valve is integrated into the extraction path in the extraction direction upstream of the incoming pressure equalization path, which opens in the extraction direction and closes in the opposite direction.
- the inflow side of the shut-off valve is thus protected by two check valves.
- the check valve integrated into the pressure equalization path prevents - analogous to the check valve in the refueling path - fuel gas from flowing out of the fuel gas tank.
- the check valve integrated into the extraction path prevents fuel gas from flowing back from the inflow side of the shut-off valve into the fuel gas tank and thus ensures that no permanent gas flow can occur via the pressure equalization path.
- the base body has a connecting section for connection to the fuel gas tank.
- the connecting The connection section can have an external thread for screwing the valve assembly into the fuel gas tank, in particular into a bottle neck of the fuel gas tank. This simplifies the installation of the valve assembly on the fuel gas tank.
- the extraction path and the refueling path are connected to a storage volume of the fuel gas tank via a common path.
- the extraction path and the refueling path are each combined into one path not only in the area of the gas connection, but also on the side of the fuel gas tank.
- only one path leads into the fuel gas tank.
- the connecting section for connecting the valve assembly to the fuel gas tank can be made smaller, which is particularly advantageous if the valve assembly is to be inserted into a bottle neck of the fuel gas tank.
- the extraction path and the refueling path can also be designed as separate paths in the connecting section of the valve assembly. In this way, a hole intersection can be saved. In this case, the extraction path and the refueling path flow into the fuel gas tank as separate paths.
- 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 using the valve closing elements.
- the two valve closing elements can be designed as balls that interact with conical valve seats. The balls do not require radial guidance as they align themselves in relation to the conical valve seats. When the valve is opened, the balls thus release a sufficient flow cross-section to connect the inflow side of the shut-off valve to the fuel gas tank via the extraction path or to the gas connection via the pressure equalization path.
- the component can have a one-piece valve closing element that can be moved back and forth between two valve seats, with a circumferential groove and at least one longitudinal groove.
- the component can be connected to the inflow side of the shut-off valve via the circumferential groove.
- the at least one longitudinal groove connects 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. In the design as a normally closed valve, it meets the safety requirements for a fuel gas tank.
- 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. 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, when filling the fuel gas tank with fuel gas and when equalizing the pressure,
- Fig. 3 a longitudinal section through two check valves opening in opposite directions, which are combined to form a component with two valve closing elements, two valve seats and a spring,
- Fig. 4 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. 5 a cross section through the component of Figure 4 and Fig. 6 shows a further longitudinal section through the component of Figure 4, but in a different switching position.
- 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 13, 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).
- the base body 3 has a withdrawal path 4 for withdrawing fuel gas from the fuel gas tank 2 and a refueling path 5 for refueling the fuel gas tank 2.
- a shut-off valve 6 is integrated into the withdrawal path 4, which can be controlled electrically and is designed as a normally closed valve.
- a check valve 11 is arranged, which opens in the withdrawal direction and closes in the opposite direction.
- a further check valve 7 is integrated into the refueling path 5, which opens in the refueling direction (arrow 24) and closes in the opposite direction.
- the withdrawal path 4 and the refueling path 5 are combined to form a path 9, which opens into the gas connection 8.
- a pressure relief path 10 branches off from this path 9, which flows into the extraction path 4 upstream of the shut-off valve 6 in the extraction direction, downstream of the check valve 11 integrated in the extraction path 4.
- the pressure equalization path 10 thus connects the outflow side with the inflow side of the shut-off valve 6.
- a further check valve 12 is integrated into the pressure equalization path 10, which blocks in the extraction direction. In the opposite direction (arrow 25), however, the check valve 12 allows pressure equalization between the outflow side and the inflow side of the shut-off valve 6.
- the extraction path 4 and the refueling path 5 are merged into a path 14, so that only this one path 14 leads into the fuel gas tank 2.
- the connecting section 13 can be dimensioned very small.
- the extraction path 4 and the refueling path 5 can also be connected as separate paths to the storage volume of the fuel gas tank 2. This embodiment is shown as an example in Figure 2. Otherwise, the embodiment of Figure 2 corresponds to that of Figure 1.
- the pressure equalization path 10 can also not open into the path 9 within the base body 3, but instead be led directly to the front face of the base body 3 or the gas connection 8, so that it opens directly into a connected external gas line.
- This embodiment is not shown separately again in the figures, since it can be derived from Figures 1 and 2.
- check valves 11, 12, which open in opposite directions and are shown in Figures 1 and 2 can be combined to form a component 15 in order to save installation space. Possible embodiments of such a component 15 are shown as examples in Figures 3 to 6.
- FIG. 3 A first preferred embodiment of a component 15 is shown in Figure 3.
- the component 15 has two valve closing elements 18.1, 18.2, each valve closing element 18.1, 18.2 being prestressed in the direction of a valve seat 16, 17 via a common spring 19 arranged between the two valve closing elements 18.1, 18.2.
- Each valve closing element 18.1, 18.2 is thus assigned a valve seat 16, 17.
- the spring 19 is accommodated in a valve chamber 22 which surrounds the component. element 15 with the inflow side of the shut-off valve 6.
- the check valve 11 opens with the valve closing element 18.1 against the spring force of the spring 19, while the valve closing element 18.2 is pressed against its valve seat 17 and thus closes the check valve 12.
- the check valve 12 opens with the valve closing element 18.2 against the spring force of the spring 19, while the valve closing element 18.1 is pressed against its valve seat 16 and thus closes the check valve 11.
- valve closing element 18 is designed in one piece and is controlled solely by pressure, i.e. pneumatically, so that a spring 19 is unnecessary.
- the valve closing element 18 has a circumferential groove 20, via which the valve chamber 22 is connected to the inflow side of the shut-off valve 6.
- Figure 4 shows the valve closing element 18 in a switching position which it assumes when P2 > pi. Pressure equalization can then be achieved via the open check valve 12, which prevents the shut-off valve 6 from opening accidentally. The check valve 11 is closed in this switching position.
- Figure 6 shows the valve closing element 18 in a switching position which it assumes when P2 ⁇ pi and the shut-off valve 6 is actively opened. Fuel gas can then be taken from the fuel gas tank 2 via the opened check valve 11 and the opened shut-off valve 6 is led to the gas connection 8. The check valve 12 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.
