Description

The utility model relates to water storage systems with a water tank, in particular for use in vehicles, for example, rail vehicles.

In rail vehicles, for example, for plumbing equipment or for on-board kitchens, there are fresh water installations with fresh water tanks. Fresh water installations are located, depending on the type of on-board equipment, in one, several or all of the train cars. Depending on the design, fresh water tanks are located, for example, in the roof area, in the interior or under the vehicle floor. In certain situations, such as when there is a risk of frost, fresh water tanks must be completely drained. Thus, the ability to ensure their simple discharge is necessary.

The utility model is based on the task of creating a water storage system with the possibility of its compact and economical implementation, in particular, in railway transport with the possibility of its reliable operation and easy labor discharge.

This problem is solved according to this utility model through a water storage system, characterized by the features of paragraph 1 of the formula. Preferred embodiments of the water storage system are disclosed in the dependent claims of the utility model.

According to a utility model, it is proposed that a water storage system has a common pipeline connected through a parsing point to an overflow pipe connected to the water tank and a drain pipe connected to the water tank, and the common pipe redirects at a water level that has reached a predetermined maximum level in the water tank or exceeds it liquid from the overflow pipe to the end of the common pipe remote from the parsing point, and in the event of a water tank drain, directs the liquid from the drain pipe to the end of the common pipe remote from the parsing point.

A significant advantage of the water storage system according to this utility model is that the proposed common pipeline provides both the possibility of redirecting liquid at an excessively high water level and redirecting liquid after a given discharge of the water tank and, thereby, partially fulfilling the function of both the drain pipe and the overflow function the pipeline. This makes it possible to make the overflow pipe and the drain pipe relatively short, which ensures the rejection of duplicate or parallel piping, in comparison with the implementation of a separate overflow and separate drain pipe. In other words, the water storage system according to this utility model provides the possibility of its implementation with saving pipelines or reducing their length and, thereby, with a minimum cost, minimum installation costs and maximum space savings.

With respect to the arrangement of the suction openings and the drain openings, it is preferable to have a suction hole in the drain pipe in the bottom area of the water tank and an overflow hole in the water tank in the overflow pipe located above the suction hole and determining the maximum fill level.

To ensure the most non-laborious drainage of the water tank, it is preferable to have a suction section in the drain pipe extending up to the height of the suction hole, higher than the height of the overflow hole, and from there down to a height below the bottom of the water tank, and the tank drain when the liquid suction section is filled only severity of fluid. In this embodiment, the so-called lifting force of liquids: when filling the suction section with liquid, the water tank is automatically drained under the influence of gravity or due to pressure drop in the pipeline.

The parsing point is preferably below the level of the overflow opening of the overflow pipe, particularly preferably below the level of the suction opening of the drain pipe.

In order to allow suction into the suction zone for draining the liquid, interrupting if necessary, or subsequently stopping the suction process caused by raising the liquid, it is preferable that there is a shut-off element in the overflow pipe between the disassembling point and the overflow hole, in particular a valve that allows the flow of fluid in the open position medium in the direction of the parsing point and, for example, draining the liquid when the filling level is exceeded, and in the closed position it reinforces or about interrupting the flow of fluid and due to this, for example, the absorption of liquid into the suction zone. This embodiment makes it possible to interrupt further discharge after the previously initiated suction process by opening the valve and creating an air connection between the suction port and the overflow port.

The valve can be made in the form of a hose pinch valve or in the form of a magnetic valve.

Given the minimum number of components, it is preferable to make a breakdown point in the form of a directional valve, in particular a 3-way 2-position valve (valve with three inlets and two positions) connected to the first supply pipe to the common pipe, the second supply pipe to the drain pipe, and the third supply pipe to overflow pipe and in the first position, overlapping the first, second and third inlet, and in the second position, opening the first and second inlet and overlapping the third inlet. In this embodiment, the directional valve forms both an adapter for connecting the overflow, drain and common pipelines, and a component capable of blocking the previously started drain.

The shut-off element or directional valve is preferably made with the possibility of remote control, in particular with the possibility of pneumatic or electrical switching. This embodiment provides the preferable possibility of remotely switching the shut-off element or the directional valve when the liquid is sucked out of the water tank and the additional liquid is sucked into the suction zone.

Taking into account the liquid suction, it is preferable to install in the common pipeline, downstream of the breakdown point, a suction device for sucking the liquid into the suction zone of the drain pipe and for filling it, which ensures subsequent automatic drainage of the tank only under the influence of the gravity of the liquid. With the latter embodiment indicated, the discharge process can advantageously be interrupted by connecting the overflow pipe to the drain pipe and thereby creating an air flow from the overflow pipe to the drain pipe.

Alternatively, the suction device is installed in the drain pipe - i.e. upstream parsing points.

The suction device is preferably made in the form of an ejector or pump.

The utility model also relates to a vehicle, in particular to a rail vehicle equipped with a water storage system described above. Regarding the advantages of the vehicle for this utility model, the above should be noted.

According to a utility model, the operation of a water storage system with a water tank is possible.

According to a utility model, it is proposed that

- in the normal operating mode, a common pipeline connected to the overflow pipe connected to the water tank and a drain pipe connected to the water tank was connected to the overflow pipe and allowed liquid to be drained through the overflow pipe, and

- in the operating mode, the liquid was drained by suction through the suction hole located at the bottom of the water tank and suction into the suction zone, which was higher up from the suction hole than the overflow hole of the overflow pipe, and from there down to a height below the water tank, and the tank was drained provided by the action of gravity of the liquid through the drain pipe and the common pipe when filling with liquid due to the absorption of the suction zone.

The utility model is disclosed in more detail using an example of its implementation using drawings, which show the following:

FIG. 1 is an example of an embodiment of a rail vehicle according to this utility model equipped with a water storage system according to an embodiment in which a valve is installed in the overflow pipe;

FIG. 2 is an example of an embodiment of a rail vehicle according to this utility model equipped with a water storage system according to an exemplary embodiment in which an overflow pipe, a drain pipe and a common pipe are connected by means of a directional valve;

FIG. 3 is an example of an embodiment of a rail vehicle according to this utility model equipped with a water storage system according to an embodiment in which the overflow pipe is located downstream of the suction device.

In the figures, for clarity, identical or similar components always have the same conventions.

In FIG. 1 shows a rail vehicle equipped with a water storage system. The water storage system includes a water tank 20, preferably located in the roof area 11 of the rail vehicle 10. The water tank 20 is preferably designed to store water, in particular fresh water, coming in via one or more pipe connections 21 not shown in FIG. 1 to consumers, e.g. toilets, washbasins, dishwashers, etc.

To fill the water tank 20 with liquid, two filling pipelines 30 and 31 are introduced into the water tank 20 and provide filling with liquid in the direction shown in FIG. 1 shooter P1.

To prevent overflow of the water tank 20, the rail vehicle 10 is equipped with an overflow pipe 40, an overflow hole 41 of which is located in the area of the water tank 20 and determines the maximum filling level. If the liquid level in the water tank 20 reaches the level of the overflow hole 41, for example, in the event of an overflow or splash during braking or acceleration of the rail vehicle 10, the liquid flows through the overflow hole 41 through the overflow pipe 40 from the rail vehicle 10.

An overflow port 41 is connected at a point of disassembly 50 to a common conduit 60 that directs fluid discharged from the water tank 20 through an overflow conduit to a drain port 62. A drain port 62 is located at an end 61 of the common conduit 60 remote from the breakdown point 50. Drain port 62 preferably located in the floor area 12 of the rail vehicle 10.

A drain line 70 with a suction hole 71, also called a suction pipe, is also connected to the disassembly point 50. A suction hole 71 is located in the bottom zone of the water tank 20 and allows the liquid to be sucked out of the water tank 20. The suction may be necessary if the rail vehicle 10 is parked in winter and there is a danger of freezing or if fluid replacement is necessary.

A suction portion 72 is adjacent to the suction hole 71, extending upward to a height greater than the height of the overflow hole 41 of the drain line 40 and then extending downward to a height below the water reservoir 20. The suction portion 72 can automatically drain the water reservoir 20 only by gravity or by account so-called lifting action of the liquid as soon as the suction portion 72 is filled with liquid.

In the embodiment of FIG. 1, a valve 42 is installed in the overflow line 40 in the region between the disassembly point 50 and the overflow hole 41, providing an open fluid flow in the direction of the disassembly point 50, and in the closed position, separating the overflow hole 41 from the disassembly point 50. In addition, the rail vehicle 10 of FIG. 1 includes a suction device 80 mounted in an area between a parsing point 50 and a drain hole 62 of a common pipe 60, i.e. downstream of the disassembly point 50. The functions of the valve 42 and the suction device 80 are described in more detail below.

The water storage system of the rail vehicle 10 is preferably operated as follows:

If it is necessary to fill the water tank 20, a liquid, such as water, is poured into the water tank 20 through the filling lines 30 and 31 in the direction shown in FIG. 1 shooter P1.

In the normal mode of operation of the water reservoir, for example, during the movement of the rail vehicle 10 through the connecting pipes 21 there is a liquid intake. The valve 42 in the overflow pipe 40 is opened in the normal operating mode of the water reservoir, so that in case of excess of the liquid level or splashing out, to ensure the flow of liquid through the overflow hole 41 and the valve 42 to the breakdown point 50, and then drain the liquid through the drain hole 62 from the rail vehicle 10. In this way, the overflow hole 41 prevents unwanted flooding of the roof area 11.

In normal operating mode, the suction device 80 is not activated, the drain pipe 70 and the suction section 72 are not involved, since there is no liquid in the section 72 and automatic drainage through the drain pipe 70 is possible only under the influence of gravity or only due to the lifting force of the liquid. Spontaneous filling of the suction portion 72, for example, due to splashing out of the liquid during movement, prevents the lower location of the overflow hole 41.

If necessary, drain the water tank 20, for example, to prevent freezing of the liquid at low temperatures, the suction device 80 is activated for a short time to suck the liquid at the suction hole 71 into the suction section 72 and completely fill it with liquid. As soon as the suction section 72 is full, the water tank 20 is drained only due to the gravity of the liquid or only due to the lifting force of the liquid, since the liquid flowing in the direction of the drain hole 62 creates reduced pressure and draws in the remaining liquid through the suction hole 71. After completely filling the suction section 72 with liquid, the liquid drains automatically, even if the suction device 80 is then deactivated; those. there is no need for continuous operation of the suction device 80.

To ensure that fluid is sucked in at the suction port 71, the valve 42 in the overflow line 40 is closed during the activation of the suction device 80, as well as during the subsequent automatic draining of the water tank 20. This prevents air from flowing through the overflow line 40 into the drain line 70 and the suction section 72 and the possibility of an undesired interruption of the discharge process due to air entering the suction portion 72.

If it is necessary to interrupt the draining process deliberately after the automatic draining of the water tank 20 has begun, this is achieved simply by opening the valve 42 and directing the air through the overflow pipe 40 to the drain pipe 70 to fill the suction section 72 with air and stop the suction of the suction section 72.

Valve 42 is made in accordance with FIG. 1, respectively, on-off. In the closed state, the valve 42 allows the suction device 80 to suck in liquid at the suction hole 71 and fill the suction portion 72 with liquid, so that then the automatic drainage of the water tank 20 is possible only by gravity; regardless of whether the suction device 80 continues to operate and suck in the liquid, the drainage of the water tank 20 continues automatically after filling in the suction section 72 and the automatic discharge starts under the influence of the lifting force of the liquid. If it is necessary to interrupt the suction of the liquid in the suction portion 72 and the resulting automatic drain, the valve 42 is opened and air is passed into the suction portion 72.

The parsing point 50 is preferably below the level of the suction hole 71 of the drain pipe 70.

In FIG. 2 shows another exemplary embodiment of a rail vehicle 10 equipped with a water storage system. The water storage system includes a water tank 20 to which several subsea pipelines 21, an overflow pipe 40, and a drain pipe 70 are connected.

In contrast to the exemplary embodiment of FIG. 1, a parsing point 50 connecting the drain pipe 70 and the overflow pipe 40 to a common pipe 60 is formed by a directional valve 100. The directional valve 100 preferably has a first inlet 101 for connecting to a common pipe 60, a second inlet 102 for connecting to a drain pipe and a third inlet 103 for connection to an overflow line 40.

The directional valve 100 preferably enables two of the following connection positions:

In the first position, also called the overflow position and performed in the normal operating mode of the rail vehicle 10, the travel valve 100 connects the first inlet 101 and the third inlet 103, i.e. a common pipeline 60 with an overflow pipe 40, to ensure that the overflow pipe 40 functions overflow. In the overflow valve overflow position 100, the second inlet 102 or drain pipe 70 is disconnected from the common pipe 60; however, it is preferable that the first, second, and third connections are connected to provide ventilation for the suction portion 72 (see below).

In the second position, also called the draining position and performed to drain the water tank 20, the directional valve 100 connects the first inlet 101 and the second inlet 102, i.e. a common conduit 60 with a drain conduit 70, so that after activating the suction device 80, liquid is sucked from the water tank 20 into the suction port 71 and, thus, to the suction section 72. In order to simultaneously prevent air intake through the overflow port 41 or overflow conduit 40, the directional valve 100 interrupts the connection between the first supply 101 and the third supply 103 in the discharge position, i.e. disconnects the overflow hole 41 from the suction hole 71 of the drain pipe 70.

If it is necessary to interrupt the previously started drainage process, in which the liquid is sucked out of the water tank 20 by its lifting force, the directional valve 100 is moved to the overflow position, which prevents further draining of the liquid from the water tank 20 through the suction section 72 in the direction of the drain hole 62. Preferably the overflow position simultaneously connects the suction portion 72 to the overflow hole 41 for venting the suction portion 72 and interrupting the suction action.

In FIG. 3 shows an exemplary embodiment of the rail vehicle 10, in which the suction device 80 is installed elsewhere. In FIG. 3 it can be seen that the suction device 80 is installed in the area of the drain pipe 70, i.e. between the suction hole 71 and the parsing point 50.

Placing the suction device 80 in the area of the drain pipe 70 makes it possible to refuse in the embodiment of FIG. 1 from an additional valve, for example from valve 42. The drawback of FIG. 3 is, however, the inability to stop draining under the influence of gravity through the drain pipe 70 after its initiation by the suction device 80.

Otherwise, for the exemplary embodiment of FIG. 3, explanations regarding FIG. 1 and 2.

Despite the detailed description and illustration of the preferred examples of implementation, the utility model is not limited to the disclosed examples of implementation, and the specialist will be able to derive from them other options for performing the utility model without violating the scope of its legal protection.
