Definitions

the invention relates to a railway vehicle with a sanitary device, is obtained at the wastewater, and connected to a sewer pipe between the sanitary device and a port for a target container for receiving wastewater, which is connected via a further connection with a sewage pipeline for emptying into a landside target container may be, with a sewer connection of the sanitary device is lower than at least a portion of the sewage pipeline, so that the waste water is to be promoted by the sewer line against the gravitational force.
the invention has the object, a rail vehicle of the type mentioned further such that frost protection of the sewage pipeline is given to a greater extent.
the sewer line has at least one non-return valve, which is arranged between the sewer connection of the sanitary device and the section of the sewage pipeline.
Such a backflow barrier causes returned wastewater to be collected at a location in the sewer pipe and discharged more effectively at a later time.
the non-return valve is arranged in a substantially horizontally extending portion of the sewage pipeline. This increases the effectiveness of the non-return valve in the sewage pipeline.
the backflow barrier can be formed by an increase and a subsequent lowering of the course of the sewage pipeline. This ensures that wastewater is prevented from flowing backward by being raised in the course of the sewage pipeline and collecting behind the lift in the conveying direction.
the increase may preferably be at least one pipe diameter. It is also possible that the increase is several pipe diameters, in any case it must be ensured that an expected amount of backflowing wastewater is reliably retained by the non-return valve.
a lying in the conveying direction of the waste water behind the backflow barrier section of the sewage pipeline can be designed to be heated, so that in the case of Supplying the sewage pipeline with frost possible damage can be safely avoided.
the sanitary device 1 which may be, for example, a toilet, a sink or a shower, connected via a sewer connection 2 to a sewage pipeline 3.
the sewage pipeline 3 opens at a port 4 of a target container 5, which serves to receive the wastewater.
the target container 5 can be present, for example, as a rail vehicle side provided wastewater container.
a sewer line between the target container 5 and another destination container is considered, which is arranged outside of the rail vehicle and is present as a shore-side suction device.
the sewage connection 2 of the sanitary device 1 is lower than a portion of the sewage pipeline 3 to the port 4 of the target container 5, so that waste water is to be conveyed against the action of gravitational force, typically by means of compressed air or vacuum.
the sewage pipeline 3 runs initially substantially horizontally from the connection 2 in the conveying direction of the wastewater, is then arranged obliquely upward therefrom and leads obliquely downwards in the region of the destination container 5 via a pipe bend.
the end of a delivery cycle involves wetting of the sewage pipe inside with wastewater.
This wastewater flows after completion of the delivery cycle to the next locally lowest point in the sewage pipeline sections against the conveying direction of the waste water back towards the sanitary device 2.
the sewage pipe 3 has a return flow barrier 6, in the flow direction of the waste water is formed by an increase and a subsequent lowering of the course of the sewage pipeline 3.
the increase corresponds to about four times a diameter of the sewage pipeline 3.
the non-return valve 6 causes not discharged wastewater from the pipe area in the conveying direction behind the return flow barrier 6 collects in the region of their lowering. This avoids that the non-pumped wastewater can flow even further towards the sanitary device 1. It is thus easier to spend at a subsequent sewage production cycle to the target container 5.
a heating device 7 is provided adjacent to the backflow barrier 6 of the sewage pipeline 3 in the flow direction of the wastewater. This heating device 7 is suitable for applying heat to the region of the wastewater pipeline 3 in which wastewater flowing back collects. As a result, in the case where frost damage to the sewage pipeline 3 is to be feared, ice formation in the sewage pipeline 3 behind the non-return valve 6 can be avoided.
non-return valve 6 does not necessarily have to have a constant pipe diameter. Rather, there are also different diameters about the pipe bend, which forms the return flow barrier 6, conceivable. Also, three-dimensional characteristics of the non-return valve 6 are possible. If required, several return flow barriers can be provided along the sewage pipeline 3.
the backflow barrier 6 is typically formed by a plurality of pipe bends, so that it is easy to assemble.
