Description

The utility model relates to the field of railway transport and can be used in top-drain tank cars for transporting liquid cargo (acid, liquefied hydrocarbon gases, liquid chemical products, etc.).

A drain device of a tank car for oleum model 15-1424 is known, shown in paragraph 4.1.1 in Fig. 4.4 in the manual "Specialized tanks for the transport of dangerous goods. Reference manual", approved. in the UMC "Train traffic safety" IPK Ministry of Railways of the Russian Federation. Association "Transbezopasnost" (01.01.1993). The drain device consists of a pipe 2, a guide funnel 1 in which the pipe 2 is installed, a hatch 3, a hinged bolt 4, a plug 5 and a fluoroplastic gasket 6. The product is poured in a closed way, and the product is drained either by pumping or by squeezing.

The technical problem inherent in this drain device of the tank car is that the drain-fill pipe is installed directly into the guide funnel, and during the movement of the car, the outer surface of the pipe rubs against the inner surface of the guide funnel, which can lead to abrasion of the drain-fill pipe and its failure, as well as the formation of a spark.

Also known is the patent RU 163209 U1, B61B 5/00, publ. 07/10/2015, which is taken as a prototype. In FIG. 2 of the indicated source shows a fragment of a boiler with a pallet. The pallet is installed symmetrically with respect to the longitudinal plane of the boiler. The drain-fill pipe is lowered into the pallet in such a way that a gap is structurally provided between the inner surface of the pallet and the end plane of the pipe. The lower part of the drain-fill pipe in the area of the pallet is kept from moving with the help of a guide funnel.

The technical problem inherent in this draining device of the tank car is the rapid contact wear of the lower end of the drain-loading pipe, which is in frictional contact with the guide funnel, as well as the possibility of spark formation in this place during the operation of the tank car.

The technical result of the claimed utility model is to exclude wear of the lower end of the drain-fill pipe of the drain device on the guide funnel and to exclude the possibility of spark formation during the operation of the tank car.

The specified technical result is achieved by a drain device of a tank car, containing a drain-fill pipe, the lower end of which is placed in a guide funnel mounted on a bracket fixed inside the tank car boiler, a replaceable sleeve made of a material is installed in the guide funnel along its inner surface, excluding sparking; fluoroplastic can be used as the material of the replaceable sleeve, which excludes sparking; stainless steel can be used as the material of the replaceable sleeve, which excludes sparking.

The claimed utility model differs from the prototype in that a replaceable sleeve made of a material that excludes sparking is installed in the guide funnel along its inner surface. Such differences from the prototype gives reason to assert that the proposed technical solution meets the criterion of patentability of a utility model - "novelty".

The essence of the claimed utility model is illustrated by the drawing.

The drain device of the tank car contains a drain-fill pipe 1, the lower end of which is placed in the guide funnel 2. The guide funnel 2 is mounted on the bracket 3. The bracket with the guide funnel 2 is fixed inside the boiler 4 of the tank car. A replaceable sleeve 5 is installed in the guide funnel 2 along its inner surface, made of a material that excludes sparking.

Fluoroplastic can be used as the material of the replaceable sleeve 5, which excludes sparking.

Stainless steel can be used as the material of the replaceable sleeve 5, which excludes sparking.

The drain device can be used in top-drain tank cars for transportation of liquid cargo (acid, liquefied hydrocarbon gases, liquid chemical products, etc.).

The technical result of the claimed utility model, which consists in eliminating the wear of the lower end of the drain-loading pipe and eliminating the possibility of spark formation during the operation of the tank car, is achieved as follows.

During the operation of a tank car equipped with a drain device with a top drain, the lower part of the drain-loading pipe is installed in a guide funnel, in which, when the tank car is rolling, the metal of the tank rubs against the metal of the guide funnel, which leads to frictional wear of the lower end of the pipe filling and draining and its failure, as well as to the possible formation of a spark. The exclusion of wear of the drain-filling pipe against the guide funnel and the formation of a spark during the operation of the tank is achieved due to the fact that a replaceable sleeve made of a material that excludes sparking is installed in the guide funnel along its inner surface. Depending on the physical and chemical properties of the transported cargo, the replaceable sleeve can be made of known polymeric materials that are inert to this cargo and replaced if it is worn out.

Thus, the claimed utility model, with its entire set of essential features, makes it possible to exclude abrasion of the drain-loading pipe of the drain device against the guide funnel and the formation of a spark during the operation of the tank car.
