Description

The utility model relates to railway transport, in particular to the designs of drain devices of railway tank cars for the transport of liquid substances with a triple degree of protection.

From the prior art, a shut-off device for a drain device is known (GB 2519984, F16K 1/00, publ. 03/20/2010), containing a body with inlet and outlet pipes and equipped with a shut-off body installed in the body in an inclined plane with respect to the cross section of the pipe.

A locking device for drain devices of railway tank cars is known (RU 92503, F16K 1/22, B61D 5/00, B67D 7/02, publ. , while the shut-off body is installed on the inlet pipe in an inclined plane with respect to the cross section of the pipe (prototype).

A general technical problem solved by the creation of the claimed utility model is to improve the throughput of the locking device of the drain device of the railway tank car to increase the speed of draining liquid substances, especially viscous liquids.

The technical result consists in improving the capacity of the drain device of a railway tank car.

The technical result is provided by a drain device of a railway tank car, containing a locking device, which, in turn, contains a housing with inlet and outlet nozzles and a locking body mounted on the inlet pipe in an inclined plane with respect to the axis of the inlet pipe, in which the axes of the inlet and outlet pipes of the outlet pipe are displaced relative to each other by a distance n, made in the range from 5 mm to 60 mm.

A comparative analysis with the prototype shows that the proposed drain device of the railway tank car differs from the prototype in that the axes of the inlet and outlet pipes are offset relative to each other by a distance in the range from 5 mm to 60 mm. Such a difference from the prototype gives reason to assert that the proposed technical solution meets the criterion of patentability of a utility model - "novelty".

The proposed utility model is illustrated by graphic material, where in Fig. 1 shows a schematic representation of the draining device of a railway tank car; in fig. 2 - an example of the implementation of the proposed drain device of a railway tank car in the "open" position.

The drain device of the railway tank car (Fig. 1) contains a locking device 1, which, in turn, contains a housing 2 with an inlet pipe 3 and an outlet pipe 4 and a shut-off body 5 installed on the inlet pipe 3 in an inclined plane with respect to the axis inlet pipe 3. The shut-off body 5 is made in the form, for example, of a butterfly valve with a control drive, the free end of which is made, for example, in the form of a steering wheel.

The technical result, which is to improve the capacity of the drain device of the railway tank car, is achieved as follows.

The axis of the inlet pipe 3 and the axis of the outlet pipe 4 are displaced relative to each other by a distance n, made in the range from 5 mm to 60 mm. Such a design of the shut-off device 1 of the drain device of the railway tank car provides an improvement in the throughput of the shut-off device 1 and the drain device of the railway tank car as a whole.

Making the distance n less than 5 mm will not ensure the achievement of the technical result, since the rate of draining liquid substances through the drain device of the railway tank car is reduced due to partial blocking of the through hole of the shut-off device 1 due to the inclined position of the shut-off body 5 of the shut-off device 1, namely its rotary damper in the “open” position, which will negatively affect the throughput of the drain device of the railway tank car. The implementation of the distance n more than 60 mm will not ensure the achievement of the technical result due to the occurrence of turbulence in the flow of transported liquid substances caused by a significant displacement of the axis of the inlet pipe 3 and the axis of the outlet pipe 4, as well as a critical reduction in the through hole of the locking device 1, which will significantly reduce the throughput ability of the drain device of the railway tank car. Also achieved is the simplification of the design of the locking element 5 of the locking device 1 and the reduction of the time for closing/opening by reducing the length of the trajectory of the rotary damper.

A specific example of the implementation of the utility model is the drain device of a railway tank car with a triple degree of protection.

The drain device of the railway tank car (Fig. 2) is assembled from three parts: the upper part 6, the middle part 7 and the lower part 8, and from three sequentially located and independently controlled gates: the upper gate (not shown in position), the lower gate (position not shown) and a locking device 1. The locking device 1 is located in the middle part 7 of the drain device. The locking device 1 includes a body 2 with an inlet pipe 3 and an outlet pipe 4, and a locking body 5. The locking body 5 is made in the form of, for example, a butterfly valve and a control actuator, the free end of which is made, for example, in the form of a steering wheel. The locking element 5 is installed on the inlet pipe 3 in an inclined plane with respect to the axis of the inlet pipe 3. The outlet pipe 4 is installed with an axis offset relative to the axis of the inlet pipe 3 by a distance n from 5 mm to 60 mm.

When transporting liquid substances in a railway tank car in a drain device, the rotary valve of the shut-off body 5 of the shut-off device 1 is in the “closed” position, tightly blocking the through hole of the inlet pipe 3. When draining liquid substances from the railway tank car through the drain device to transfer the shut-off body 5 of the locking device 1 from the "closed" position to the "open" position rotate the control actuator, the free end of which is made, for example, in the form of a steering wheel. The displacement of the axis of the inlet pipe 3 and the axis of the outlet pipe 4 relative to each other by a distance n at the position of the rotary valve of the locking body 5 in the "open" position inside the body 2 of the locking device 1, completely frees the through hole of the outlet pipe 4 of the locking device 1, ensuring unimpeded draining of liquid substances from a railway tank car.

Thus, the claimed utility model provides an improvement in the capacity of the locking device and the drain device of the railway tank car as a whole.
