Definitions
- the invention relates to a rail vehicle with a gray water line, which is connected via a reservoir or directly to an environment of the rail vehicle, the gray water line is equipped with a pressure relief valve, which is located upstream of the pressure protection valve portion of the greywater line against in the area protects the rail vehicle occurring pressure surges.
- a pressure-tight passenger compartment plays an important role in driving Kgs ⁇ NEN, especially in a tunnel or at a Switzerlandbegeg ⁇ voltage, differences between an ambient pressure and a carriage internal pressure occur that produce pressure fluctuations in the passenger compartment, to reduce reasons of comfort, are. Therefore, every leaking of the car should be through which
- the greywater line connects the drains of a hand wash basin
- the collecting container is arranged outside the passenger compartment in Unterflurbe ⁇ rich. It has an overflow pipe which provides a permanent open connection to the environment.
- the greywater line must be provided with a pressure protection solution that does not prevent the drainage of gray water.
- the gray water line is equipped with a valve.
- AI ei ⁇ ne beak valve which consists of a specially shaped rubber element, which is installed in the course of gray water pipe.
- the design is such that the Gummiele ⁇ element runs lying flat on one another. If this element belas ⁇ tet from its upstream side with water, the weight of the water pushes apart the element, so that the water can flow.
- a downstream occurring defects ⁇ tender pressure surge does not allow that this Ven ⁇ til opens. On the contrary, overpressure compresses the element only more closely , so that pressure transmission in the direction of the interior of the rail vehicle is effectively avoided.
- This embodiment of a valve works passively and ver ⁇ closes the opening type of construction is not permanent or from ⁇ solut. Based on this, the present invention seeks to gozuentwi ⁇ ckeln the aforementioned rail vehicle such that a better protection against pressure surges in its environment is possible.
- This object is achieved in that the pressure protection valve is designed as a pinch valve, which is controlled by a control ⁇ device to protect the portion of the greywater line from pressure surges.
- valve which serves to protect the upstream portion of the gray water line is actively controlled, thereby effectively improving the protection against external pressure surges.
- the control device opens or closes the pinch valve, depending on an operation of a water consumer connected to the gray water pipe, which is detected by means of a sensor.
- a sensor For example, an operation of a water faucet ⁇ at a hand wash basin with the aid of a sensor can be construed ER.
- this sensor outputs a signal representing an actuation of the faucet, this signal is passed to the control device for the pinch valve, so that the pinch valve, which otherwise can be permanently closed, is opened.
- the control device can control the pinch valve as a function of a signal coming from the train controller of the rail vehicle, for example.
- a signal indicates whether a pressure surge is to be expected from the surroundings of the rail vehicle or a general operating situation of the rail vehicle is such that a high probability of pressure surges is given.
- coming from the train ⁇ control signal may be a speed signal and evaluates such ⁇ out by the control means for the pinch valve to be that exceeding a threshold value for the speed signal prevents an opening of the pinch valve comparable. This is based on that high speeds bring an increased likelihood of pressure surges with it so that at these speeds the pinch Güns ⁇ term way is kept closed.
- a pressure surge signal is generated, which controls the pressure protection flaps of an air conditioner and this closes when needed.
- This pressure surge control signal can be used to close the pinch valve in the event of a pressure surge occurring by means of the control device.
- the control device may open or close the pinch valve, depending on a pressure surge detected by means of a pressure sensor.
- the gray water pipe or the collecting tank for gray water may be equipped with the pressure sensor for detecting a pressure pulse, wherein the pressure sensor is arranged downstream of the pinch valve, ⁇ expresses otherwise, on an outward side of the pinch valve.
- a signal generated by the sensor, which reproduces the presence of a pressure surge, is fed to the control device for the pinch valve, which then closes the pinch ⁇ valve.
- This can also apply, for example, if, as explained above, is signaled by a sensor on a faucet whose operation.
- the procedure is that the avoidance of penetration of a pressure surge in the interior of the vehicle always has priority ge ⁇ genüber a speedy discharge of gray water is obtained.
- the control means for the pinch valve can control a further pinch valve, which is ge ⁇ switched in series to the pinch valve, wherein said control means controls the two pinch valves such that always at least one of the pinch valves is closed. In this way it is ensured ⁇ that the gray water pipe is always closed by at least one of the two pinch valves provided so that rebounds can not pressurize the interior of the rail vehicle. For the removal of greywater, the pinch valves can be alternately opened and closed.
- Figure 1 is a schematic view of a sanitary arrangement of a rail vehicle in a first exporting ⁇ approximate shape
- Figure 2 is a schematic view of a sanitary arrangement of a rail vehicle in a second exporting ⁇ approximate shape
- Figure 3 is a schematic view of a sanitary arrangement of a rail vehicle in a third exporting ⁇ approximate shape
- Figure 4 is a schematic view of a sanitary arrangement of a rail vehicle in a fourth exporting ⁇ approximate shape
- FIG. 5 shows a schematic view of a sanitary arrangement of a rail vehicle in a fifth embodiment.
- a faucet 1 is illustrated, which can be opened via an actuating sensor 2 and is supplied via a water supply line 3 with fresh water.
- Greywater is collected in a sink 4, which can be considered together with the faucet 1 as a water consumer, and leaves this via a gray ⁇ water line 5.
- a pneumatically controllable pinch valve 6 is provided at the downstream end of a pneumatically controllable pinch valve 6 at the downstream end of a pneumatically controllable pinch valve 6 is provided. Via a control line 7 controls a control device 8 for the
- the pinch valve 6 is controlled via the control device 8 so that it is kept basically closed, so that occurring in the vicinity of the rail vehicle
- control device 8 is connected via a control line 12 signals connected to the actuating sensor 2 for the faucet 1.
- actuation sensor 2 actuation a loading of the faucet 1, 8 opens the control ⁇ means the pinch over a period of a complete drainage of the Greywater allowed.
- the variant of FIG. 1 is supplemented insofar as the control device 8 for the pinch valve 6 is additionally connected to a signal source 13, which signals an expected pressure surge via a control line 14.
- the signal source 13 may be, for example, a train control of the rail vehicle.
- a control signal is, for example, be generated, representing a Ge ⁇ speed of the rail vehicle. Since it can be assumed from ⁇ that an increased speed bump also an increased probability of the occurrence of printing brings with it that can be evaluated via the control line 14 coming from the control-speed signal such that, above a speed ⁇ threshold lying speeds closing the pinch valve 6 by pulling.
- FIG. 3 now shows an embodiment in which the control device 8 is connected to a separate pressure sensor 16 for the purpose of reproducing a pressure surge via a signal line 15.
- the pressure sensor 16 is located downstream of the pinch valve 6, in particular beyond the car body ⁇ wall 9 on an outer side of the rail vehicle. Once the pressure sensor 16 detects a pressure surge, that of the STEU ⁇ er adopted 8 is signaled, which then closes the pinch valve. 6 As long as the pressure sensor 16 does not signal auftre ⁇ border pressure surge, the pinch valve 6 ge ⁇ remain open.
- the embodiment according to FIG. 4 differs from that according to FIG. 3 in that the pressure sensor 16 is provided on a collection container 17 for greywater.
- the pressure sensor 16 is arranged in the discharge line 11 for detecting a pressure surge
- the drain line 11 opens directly on a track.
- the gray water is discharged via the drain pipe 11 is collected in the collection container 17, which is evacuated at a later time.
- a signal connection between the actuating sensor for the faucet 1 and the control device is not 8
- an additional signaling of the Betreliistszu ⁇ object of the faucet 1 of the control device 8 would also in the embodiments according to Figures 3 and 4 possible.
- FIG. 5 a further embodiment is illustrated, in the downstream of the washbasin 4 two Pinch valves 61, 62 are connected in series and are in each case with the control device 8 in a signal connection.
- the control device 8 is, as in the embodiments according to Figures 1 and 2, connected via the control line 12 with the actuating sensor 2 for the faucet 1.
- the control device 8 controls the pinch valves 61, 62 in such a way that one of the two pinch valves 61, 62 is CLOSED ⁇ sen. For example, if the hand basin 4 is used, first the pinch valve 62, which is closer to the hand basin 4 than the pinch valve 61, opened via the control device 8, so that the gray water collects in front of the closed pinch valve 61.
