The best option.

The passenger car’s plumbing system contains a water tank 1 located under the car’s roof, with a gas line 2 and a supply pipe 3, a pipe network 4, the input of which is connected to the output of the water tank, and the outputs to the inputs of the devices for washing (washing) passengers, washing dishes and other water consumers with taps and wastewater outlets 5, which are connected to a common drain pipe 6, toilets with flushing nozzles 7, to which the output of a water-pressure device with a controlled valve 8 is connected, made, for example, in the form of sokonapornogo water pump with a hydraulic accumulator and a controlled valve at the outlet, the shutter device 9 at the toilet outlet with flushing nozzles 7, made, for example, in the form of an electromechanical device, the input of which is connected to the output of the control unit or in the form of a pneumatic device, the input of which is connected to a vacuum network or in the form of a water lock connected to the sewer pipe 10, as well as a vacuum unit 11, the output of which is connected to the atmosphere, a storage tank with thermal insulation and heating devices 12, is located minutes under the car and having two branches, the first sewage 13 and second 14 for sewage,

separated by a sealed partition 15, which can be made of metal or alkali-acid-resistant rubber.

The first compartment 13 contains an inlet pipe 16, which is connected through the sewage filter 17 to the outlet of the common flush pipe 6, a flow pipe 18, one end of which is located near the bottom of the compartment 13 of the storage tank 12, and the second is connected to the input of the water-pressure device with a controlled valve 8 , an overflow pipe 19, a non-return air valve 20 in its upper part and a waste water drain valve 21 in its bottom, and the second compartment 14 has two inlets in its upper part, one of which is connected to the input of the vacuum unit 11, and the other is connected to the output can lizatsionnoy pipe 10, and one or two outlet with devices for pumping sewage 22 and control unit 23, which outputs are connected to a water apparatus with a controllable valve 8 and the vacuum assembly 11.

A variant is also possible in which a wastewater disinfector 24 is installed between the wastewater filter 17 and the inlet pipe 16.

The operation of the device.

The device operates as follows.

When preparing the car for operation, the water tank 1 is refilled, through the filling line 2 until water emerges from the supply pipe 3, as a result, water is supplied from the water tank 1 to the pipeline network 4 of the car, and through it to the entrances of the devices for washing (washing) passengers and washing dishes and other water consumers with wastewater outlets 5 that are connected to a common drain pipe 6.

During the operation of the wagon, the wastewater flows through a common drain pipe 6 through the wastewater filter 17, and when the wastewater disinfector is installed and through it, through the inlet pipe 16 into the compartment 13 of the storage tank 12. At the beginning of the operation of the wagon, when filling it with water, pour a little into this compartment

the amount of clean water (10 ... 15 liters), for example, through a sink 5.

During the operation of the car, all wastewater from washbasins, sinks, and souls is discharged into a common drain pipe 6 and, being cleaned with a filter 17 and disinfected with a disinfectant 24, enters the compartment 13 of the storage tank 12, and upon command from the control unit 23, the vacuum unit 11 is turned on, which creates a vacuum in the compartment 14 of the storage tank 12, preparing the toilet system for operation.

When turned on from the control unit 23, the water-pressure device 8, using a controlled valve, sucks the wastewater from the compartment 13 of the storage tank 12 through the flow pipe 18 into the toilet flush nozzles 7, while the shutter device 9 opens at the outlet of the toilet 7 and fecal water from the toilet 7 through the sewer pipe 10 under the action of vacuum enter the compartment 14 of the storage tank 12.

When the compartment 13 of the storage tank 12 is overflowed with waste water, its surplus is poured onto the railway track through an overflow pipe 19.

The non-return air valve 20 serves to exit excess air from the compartment 13 of the storage tank 12 when wastewater enters it, and the wastewater drain valve 21 is used to discharge all remaining wastewater to the railroad track when the car is stopped.

The implementation of the sealed partition 15 of alkali-acid-resistant rubber, when draining waste water from the compartment 13 of the storage tank 12, eliminates the destruction of the body of the latter during freezing of fecal water in its compartment 14 due to the bending of the partition 15 towards the compartment 13.

From the above it is seen that the introduction of a set of distinctive features in the utility model can significantly reduce water consumption in the car during operation, as well as increase its sanitary and technical parameters and equipment reliability.
