Definitions
- Tank device for storing a gaseous medium
- the invention relates to a tank device for storing a gaseous medium, in particular for storing hydrogen, for example for use in vehicles with a fuel cell drive or for use in vehicles with a hydrogen combustion engine as the drive.
- DE 10 2018 201 055 A1 describes a tank device with at least one storage unit which has a control valve and which is connected to an outlet line via a line system. At least one control valve of at least one storage unit is designed as a main valve, and at least one control valve of at least one storage unit is designed as a secondary valve, with the main valve and the secondary valve being designed differently.
- the safety devices for such a tank device are standardized. Each tank device must have such a shut-off valve. In the event of damage to the tank device caused by an accident involving the vehicle with a fuel cell drive or if a line in the tank device breaks, the shut-off valve can close the tank container so that no gas can escape from the tank device.
- shut-off valves Due to the high safety requirements for the shut-off valves and due to high system pressures of, for example, 800 bar or more, such shut-off valves are structurally very challenging and have a large installation space. This in turn increases the total weight of the entire tank device, which in the event of an accident involving the vehicle with a fuel cell drive can lead to high acceleration forces occurring and possible deformation of the valve device or the tank device.
- the tank device according to the invention with the characterizing features of claim 1 has the advantage that a compactly designed tank device with a safety valve with a positive energy balance and compliance with all safety-related criteria is provided in a structurally simple manner.
- the tank device for storing a gaseous medium, in particular hydrogen has a valve device, a tank and a longitudinal axis.
- the valve device also has a valve housing, in which valve housing a pilot valve element that can be moved along the longitudinal axis is arranged.
- the pilot valve element cooperates with a first valve seat to open and close a first outlet opening and thus forms a pilot valve.
- the valve device can be controlled by means of a magnetic coil.
- a main valve element is arranged in the valve housing, which main valve element interacts with a second valve seat to open and close a second outlet opening and thus forms a main valve.
- the tank device also includes a screw-in housing element, with the valve device being firmly integrated in a neck region of the tank by means of the screw-in housing element.
- the valve device is arranged in a closed position by means of a tank pressure in the tank and by means of a spring when the magnet coil is switched off.
- the screw-in housing element has an integral part with a first thread and a pot-shaped end with a second thread.
- a through-channel is formed in the screw-in housing element, via which through-channel the tank is connected to the valve device. This leads to greater robustness of the entire tank, especially in the event of an accident.
- the second valve seat is formed downstream on the valve housing and on the outlet opening and the cylindrical outlet opening opens into a cylindrical through-channel, with a diameter D of the through-channel being larger than a diameter d of the outlet opening.
- the passage channel merges into the outlet opening by means of a conical transition area.
- the tank device has a fixing element, through which fixing element the valve device is firmly connected to the screw-in housing element and the valve device is thus fixed to the screw-in housing element.
- the through-channel can be connected to a tank interior by means of an inlet opening formed in the valve housing and a through-channel of the screw-in housing element.
- the flow cross section of the gaseous medium from the tank can thus be controlled in a simple manner.
- the spring is arranged in a recess of the pilot valve element and a spring chamber is formed, by which spring the pilot valve element and the main valve element are subjected to a force in the direction of the valve seat. In this way it can be ensured that the pilot valve element is pressed against the valve seat with the aid of the force of the spring and the pressure difference between the tank and the through-channel. The tightness of the valve device is thus ensured when the magnet coil is not energized.
- the pilot valve element has a longitudinal opening and a transverse bore, which longitudinal opening and which transverse bore are fluidly connected to the spring chamber. In this way, the gaseous medium can be guided through the valve device in an optimal manner.
- a control chamber is formed between the valve housing and the main valve element, in which control chamber a spring is arranged, which spring acts on the main valve element with a force counter to the direction of the second valve seat.
- the main valve element has a discharge channel, which discharge channel opens into a through-opening, the through-opening opening into the outlet opening.
- the first valve seat is formed on the main valve element and the second valve seat is formed on the valve housing.
- the tank device described is preferably suitable in a fuel cell arrangement for storing hydrogen for the operation of a fuel cell.
- the tank device described is also suitable for storing hydrogen in a fuel cell-powered vehicle.
- the tank device described is also suitable for storing hydrogen in a hydrogen-powered vehicle, for example a vehicle with a hydrogen combustion engine as the drive.
- the drawing shows an exemplary embodiment of a tank device according to the invention for storing a gaseous medium, in particular hydrogen. It shows in
- Fig.l an embodiment of a tank device according to the invention with a valve device in longitudinal section. Description of the embodiment
- FIG.l an embodiment of a tank device 1 according to the invention is shown with a longitudinal axis 11 for a gaseous medium.
- the tank device 1 has a tank 10 and a valve device 2 .
- the tank 10 has a tank housing 47 in which a tank interior 100 is formed.
- the tank housing 47 also includes a neck area 6 into which the valve device 2 is integrated by means of a screw-in housing element 24 .
- a connection point in the form of a thread is attached in the neck area 6 so that the valve device 2 can be screwed into the tank 10 by means of the screw-in housing element 24 . Furthermore, a fixing element 12 is provided, which firmly connects the valve device 2 and the screw-in housing element 24 to one another, for example by means of a screw connection.
- the screw-in housing element 24 has a projection 240 on which a first thread 241 is formed, so that this can be easily introduced into the neck region 6 of the tank 10 .
- the screw-in housing element 24 has a pot-shaped end 242 in which the valve device 2 is accommodated.
- the cup-shaped end 242 also has a second thread 243 onto which the fixing element 12 can be screwed when the valve device 2 is fixed to the screw-in housing element 24 .
- a through-channel 244 is formed in screw-in housing element 24, so that gaseous medium, in particular hydrogen, can be fed in this way, for example, to an anode region of a fuel cell in a fuel cell arrangement via valve device 2 from tank interior 100 via a cylindrical through-channel 80.
- the valve device 2 has a valve housing 20 in which a cylindrical inlet opening 28 is formed, with the inlet opening 28 opening into the through-channel 244 of the screw-in housing element 24 . Both the inflow and the outflow of the valve device 2 take place here axially to the longitudinal axis 11 of the tank device 1. Furthermore, a magnetic coil 14 is accommodated and integrated in the valve housing 20, the magnetic coil 14 being fixed in the valve housing 20 by means of a support element 22 and sealed against an interior region of the valve device 2 by means of sealing elements on the support element 22. The magnet coil 14 can be controlled via an electrical connection 30 .
- a pilot valve element 18 movable along the longitudinal axis 11 is arranged in the valve housing 20 .
- the pilot valve element 18 has a recess 45 in which a spring chamber 25 is formed.
- a spring 26 is arranged in this spring chamber 25 .
- the pilot valve element 18 has a longitudinal opening 33 and a transverse bore 180 which are fluidically connected to the spring chamber 25 .
- the spring chamber 25 also opens into the inlet opening 28.
- a main valve element 19 is arranged coaxially to the pilot valve element 18 in the valve device 2 , the main valve element 19 partially surrounding the pilot valve element 18 .
- a transverse bore 190 is formed in the main valve element 19 and opens into the transverse bore 180 of the pilot valve element 18 .
- the main valve element 19 has a first outlet opening 56 which opens into a passage opening 57 . This in turn opens into a second outlet opening 31.
- a first valve seat 27 is formed on the main valve element 19 and interacts with the pilot valve element 18 to open and close the first outlet opening 56 and thus forms a pilot valve 44 .
- a second valve seat 40 is formed on the valve housing 20 and interacts with the main valve element 19 to open and close the second outlet opening 31 and thus forms a main valve 191 .
- the second valve seat 40 is formed on the downstream of the valve housing 20 and the second outlet port 31 .
- a control chamber 32 is formed between the valve housing 20 and the main valve element 19 , in which a spring 7 is arranged, which acts on the main valve element 19 with a force counter to the direction of the second valve seat 40 .
- the spring 26 in the spring chamber 25 applies a force to the pilot valve element 18 and the main valve element 16 in the direction of the second valve seat 40.
- the spring 26 is supported on the one hand on the screw-in housing element 24 and on the other hand on the pilot valve element 18.
- the through-channel 80 opens into the second outlet opening 31 by means of a conical transition area 36, the through-channel 80 having a diameter D and the second outlet opening 31 having a diameter d.
- the diameter D of the passage 80 is larger than the diameter d of the second outlet opening 31.
- the valve housing 20 is designed here in multiple parts, so that the magnetic coil 14 is accommodated and integrated between the multi-part valve housing 20 . Furthermore, the valve device 2 can be controlled by means of the magnetic coil 14 .
- a pressure P2 in the tank 10 is also greater than a pressure pi in the passage 80, so that in addition to the force of the spring 26, another closing force acts on the pilot valve element 18 and the main valve element 19 and the valve device 1 is in a closed position when the solenoid coil 14 is de-energized is arranged.
- valve device 2 The functioning of the valve device 2 is as follows: When the magnetic coil 14 is energized, a magnetic field is formed, which leads to a force acting between the screw-in housing element 24 and the pilot valve element 18 . This generates a magnetic force on the pilot valve element 18 which opposes the force of the spring 26 and the pressure forces generated by the gaseous medium. With a sufficiently high magnetic force, the pilot valve element 18 lifts off the first valve seat 27 and provides an opening cross section between the inlet opening 28 and the Passage channel 80 free.
- Gaseous medium now flows out of the tank interior 100 via the inlet opening 28, the spring chamber 25, the longitudinal opening 33, the outlet channel 56 and the through-opening 57 into the through-channel 80 via an inlet line 50 in the direction of an inlet area 55 of a consumer system, for example in the direction of an anode area fuel cell assembly.
- Gaseous medium now also flows through the second Valve seat 40 from the tank interior 100 via the inlet opening 28, the spring chamber 25, the longitudinal opening 33, the transverse bore 180 of the pilot valve element 18, the transverse bore 190 of the main valve element 19 via the control chamber 32 into the through-channel 80 via the inflow line 50 in the direction of the inflow area 53 Consumer system, for example in the direction of an anode area of a fuel cell assembly.
- the pilot valve element 18 and the main valve element 19 thus move again in the direction of the first valve seat 27 and the second valve seat 40 and thus seal the opening cross sections on the first valve seat 27 and the second valve seat 40 again.
- Gaseous medium now no longer flows out of the tank device 1 via the valve device 2 in the direction of the inlet area 53.
- the principle of the automatic closing of the valve device 2 also works in an emergency, for example if the power supply is interrupted. In this way it can be ensured that the hydrogen is enclosed in the tank device 1 and that it is not released into the environment in an uncontrolled manner.
- the direction of flow runs from an external refueling station 54 via the inlet line 50 and the valve device 2 in the direction of the tank interior 100. Since current must not be supplied during refueling, the valve device 2 must be designed in such a way that the valve device 2 can be pressed open via the pressure conditions present at the valve device 2 . Since the pressure in the passage duct 80 is greater than in the area of the main valve element 19 when refueling, the pressure conditions must be designed in such a way that the main valve element 19 can be pressed and opened against the force of the spring 26 and the pressure in the tank 10 so that the Tank 10 can be filled with gaseous medium, such as hydrogen.
- gaseous medium such as hydrogen
- the same pressure conditions are established in front of and behind the second valve seat 40 so that the valve device 2 is closed again via the force of the spring 26 .
- the tank interior 100 can thus be filled with hydrogen via the feed line 50, which is then connected here to an external filling station 54, via the same valve device 2 as the hydrogen is made available to the supply system.
- the tank device 1 for storing a gaseous medium can be used in addition to fuel cell-powered vehicles, for example, for hydrogen storage in vehicles with a hydrogen combustion engine as the drive.
