Definitions
- the invention relates to a shut-off valve for a pressurized gas container with the features of the preamble of claim 1.
- the invention relates to a pressurized gas container with such a shut-off valve.
- the pressurized gas container should in particular be able to be used to store hydrogen, preferably in mobile applications, for example in fuel cell vehicles.
- Fuel cell vehicles require hydrogen and oxygen to operate the fuel cells. While the oxygen can be taken from the ambient air, the hydrogen is usually carried along in pressurized gas containers on board the vehicle. The pressure in these containers is usually above 500 bar and is hereinafter referred to as high pressure.
- shut-off valve of the pressurized gas container. This opens against the high pressure in the pressurized gas container. Since a comparatively large cross-section has to be opened for the necessary flow, a high initial opening force is required. In the case of an electromagnetically operated shut-off valve that is switched directly, this means that large magnetic forces must be applied. Alternatively, an indirectly switched shut-off valve can be used, which is switched via a pilot valve, for example. By opening an initially small cross-section, pressure equalization can be brought about so that less force is required for the subsequent complete opening of the shut-off valve. Indirectly switched However, compared to directly switched valves, valves have a significantly more complex structure, which is reflected in a large number of parts.
- the present invention has the object of giving a shut-off valve for a pressurized gas container, which enables high actuating forces for the initial opening and at the same time is simply built on.
- shut-off valve with the features of claim 1 is proposed.
- Advantageous further developments of the invention can be found in the subclaims.
- a pressurized gas container with such a shut-off valve is specified.
- the shut-off valve proposed for a pressurized gas container comprises a liftable valve closing body which is biased against a valve seat by the spring force of a closing spring, so that in the closed position of the valve closing body a connection between a valve inlet and a valve outlet is interrupted.
- the shut-off valve also includes an actuator for opening the valve closing body.
- the actuator interacts with an actuator which is arranged at a distance coaxially from the valve closing body and can be moved in the direction of the valve closing body with the aid of the actuator so that an opening pulse can be generated with stops of the actuating member on the valve closing body.
- the proposed shut-off valve is therefore switched directly with the help of the actuator and the actuating element.
- the initially high opening force in the case of a directly switched valve is brought about in the proposed shut-off valve by a pulse that results from the movement of the actuator. Because the kinetic energy of the actuator is converted into a force when it hits the valve-closing body, which lifts the valve-closing body out of the valve seat against high pressure. Since the pressure is equalized after the initial opening, full opening can then be effected with significantly reduced force.
- the movement of the actuating element required to generate the opening pulse can be brought about with comparatively low actuating forces, so that the actuators can be correspondingly small. At the same time, the number of parts is reduced because the proposed shut-off valve is switched directly.
- the actuator system and / or the actuating element is or are biased by the spring force of a return spring.
- the spring force of the return spring counteracts the direction of force of the actuators. With the help of the return spring, the required return can thus be brought about. Because so that the actuator can be set in motion by means of the actuator and the actuator can absorb sufficient kinetic energy, a predetermined distance between the valve closing body and the actuator must be maintained in the closed position of the shut-off valve.
- the actuator system and the actuating element are preferably coupled, or at least can be coupled, so that with the preloading of one component, the other component in each case is also preloaded or can be reset via the return spring.
- the actuator system preferably comprises a linearly acting actuator, for example a magnet, piezo or eddy current actuator.
- the direction of force of the actuator can thus be optimally aligned with the direction of movement of the actuator.
- it can have a “repulsive” or “attractive” effect on the actuator.
- the type of action determines whether the actuator is arranged in front of or behind the actuating element.
- the actuator can have a repulsive effect.
- the actuator is arranged behind the actuating member, that is to say on the side of the actuating member facing away from the valve closing body.
- the actuator can in particular be a type of plunger with an at least partially elongated body.
- the actuating element be a push rod.
- the actuating member be manufactured at least partially or partially from a magnetic material. This enables the use of a magnetic actuator.
- a magnetic actuator can be used to exert a repulsive or attractive effect on the actuator.
- the actuator can, for example, be a permanent magnet or include such a magnet.
- the actuator system preferably comprises an actuator space for receiving the actuator.
- the return spring can also be arranged in the actuator space.
- the actuator chamber can be sealed off from a pressure gas-leading area of the shut-off valve and can be vented via a ventilation duct.
- the seal can be realized in particular in the area of a guide of the Actuating member.
- the volume or pressure compensation required for the movement of the actuating member can be effected via the ventilation channel.
- compressed gas can be discharged via the ventilation channel, which gas enters the actuator chamber by way of the leakage.
- the actuator space can also be connected to an area of the shut-off valve that carries pressurized gas. Sealing measures are unnecessary in this case.
- the opening stroke of the valve closing body is preferably limited by a stop.
- the stop defines an end position of the valve closing body.
- the opening cross section of the shut-off valve is preferably a maximum.
- an electromagnet is also preferably arranged, by means of which the valve closing body can be held in the open position. With the help of the magnetic force of the electromagnet, the spring force of the closing spring can thus be overcome, which biases the valve closing body in the direction of the valve seat. Since the required holding forces are comparatively low, a correspondingly small electromagnet can be used.
- the valve closing body and / or the valve seat is or are at least partially conical.
- the valve closing body is self-centering in relation to the valve seat when it is closed, so that the shut-off valve closes tightly.
- the valve closing body can be guided over the closing spring and / or a guide cage. The guidance of the valve closing body ensures an optimal alignment of the valve closing body with respect to the valve seat and thus a tight closing of the shut-off valve.
- the proposed shut-off valve is arranged in such a way that the valve inlet is or can be connected to the compressed gas container. There is thus high pressure in the valve inlet of the shut-off valve. This means that the shut-off valve opens against high pressure.
- the advantages of the invention come into effect optimally.
- a pressurized gas container with a shut-off valve according to the invention is proposed.
- the advantages of the shut-off valve also extend to the pressurized gas container.
- the compressed gas container can be used, for example, to store hydrogen, so that the problems described at the beginning are solved with the aid of the compressed gas container or with the aid of the shut-off valve of the compressed gas container.
- Fig. 1 is a schematic longitudinal section through an inventive Absperrven valve in the closed position
- Fig. 2 is a schematic longitudinal section through the shut-off valve of FIG. 1 when activating the actuator and
- Fig. 3 is a schematic longitudinal section through the shut-off valve of Fig. 1 in fengnagna Of. Detailed description of the drawings
- the shut-off valve 1 shown in FIGS. 1 to 3 has a valve closing body 2 which is movable back and forth between a valve seat 4 and a stop 13.
- the valve closing body 2 is pretensioned against the valve seat 4 by means of the spring force of a closing spring 3.
- a valve inlet 5 is connected to a valve outlet 6.
- the valve inlet 5 has a connection to a high-pressure connection 15, via which the shut-off valve 1 is connected or can be connected to a pressurized gas container (not shown).
- the shut-off valve 1 shown also has an actuator 7 which interacts with an actuating member 8. This is in the closed position of the shut-off valve 1 and with currentless actuator 7 at a distance coaxially to the valve closing body 2 is arranged (see Fig. 1).
- the actuator system 7 is arranged behind the actuating element 8. If an actuator of the actuator system 7 is energized, the actuator forces move the actuator 8 in the direction of the valve closing body 2 (see Fig. 2) this leads to the valve closing body 2 being lifted out of the valve seat 4 against the spring force of the closing spring 3 and against high pressure. A first opening cross-section is released, which leads to the pressure downstream of the valve seat 4 being equal to the pressure upstream.
- the actuator of the actuator system 7 and the restoring spring 9 are arranged in an actuator space 10 which is sealed off from an area 11 carrying compressed gas. This means that the actuator does not come into contact with the compressed gas.
- the seal is effected via a guide 16 of the actuating member 8.
- a ventilation duct 12 is provided for venting the actuator space 10.
