Description

The inventive utility model relates to railway transport and relates to freight tank wagons, in particular, designs of drain valves.

The known design of the drain device [RF patent for the invention No. 2267421, published January 10, 2006], comprising a housing surrounded by a heating casing and a main shutter. The main shutter includes a rod, the upper end of which is made with a hinged door, and the lower screwed into the rack. At the bottom, the rod is connected to a valve having upper and lower feathers, a rubber ring reinforced with a clamping ring and bolts. The main shutter is equipped with a fifth and persistent cup, and a through hole is made in the valve into which the heel is mounted and rigidly fixed, and a persistent cup is rigidly connected to the rod, into which the heel is installed and connected to it by bolts passing through its annular groove. Also, the drain device has an additional shutter, consisting of a cover with a rubber sealing ring, which is fixed to the cover by a ring and bolts, while the cover is fixed to the housing tip with a screw, and the screw support is made in the form of a folding bracket suspended on rollers that are mounted on the tip corps. The cover of the additional shutter is equipped with a lock nut with a handle. In addition, the drain device has an intermediate shutter installed between the main and secondary shutter behind the heating casing. The intermediate shutter is made of a detachable housing, inside of which a travel stop and a valve are installed, while a seal is attached to the valve using a pressure ring and fasteners.

This design is selected as a prototype for the claimed utility model.

Significant disadvantages of this design are the complexity of the assembly and installation of the locking and drain device. In addition, the centering of the main valve relative to the drain neck due to the lower and upper feathers deteriorates over time, as the feathers are erased and also break, which in turn leads to a loose closing of the main valve and leakage of the transported product.

The objective of the claimed utility model is to create a design of a locking and draining device of the tank car, which will increase the reliability of the locking and draining device by reducing distortions between the mating parts of the assembly, and will also ensure accurate, high-quality, technological assembly and installation of the locking and draining device of the tank car, will reduce labor costs during the operation and repair of the device.

The problem is solved due to the fact that the governing body of the shut-off and drain device of the tank car is made in such a way that an annular groove is made on the surface of the hull, and an annular protrusion is made on the rack flange, which, when the shut-off and drain device is installed in the boiler of the tank car, enters in the above annular groove.

The essence of the proposed design lies in the fact that the shut-off and drain device of the tank car includes a body and a main shutter, consisting of a valve pivotally connected through the heel to the lower part of the rod, which is screwed into the stand, consisting of a sleeve and a flange connected between by ribs, while on the upper part of the rod the control element of the locking and drain device is installed, along with this, on the surface of the housing on which the rack flange is mounted, an annular groove is made, into which the annular protrusion enters unitary enterprise made on a rack flange.

Also, a limiter is installed between the lower part and the threaded part of the rod, which prevents the threaded part of the rod from completely unscrewing from the rack.

The essence of the claimed utility model is illustrated by drawings:

FIG. 1 is a general view of the shut-off and drain device of the tank car;

FIG. 2 is a section AA of FIG. one;

FIG. 3 - remote element B of FIG. 2;

The locking and drain device of the tank car 1 includes a housing 2 and a main shutter 3, consisting of a valve 4, pivotally connected through the heel 5 to the lower part of the rod 6, which is threadedly screwed into the rack 7, consisting of a sleeve 8 and a flange 9 connected between each other by ribs 10. On the upper part of the rod 6 is installed the control element of the locking and draining device. Along with this, on the surface 11 of the housing 2, on which the flange 9 of the rack 7 is mounted, an annular groove 12 is made, into which an annular protrusion 13 is formed, made on the flange 9 of the rack 7.

In addition, between the lower part and the threaded part of the rod 6, a limiter 14 is installed that prevents the threaded part of the rod 6 from completely unscrewing from the rack 7.

The technical result of the claimed utility model is that the execution on the surface of the housing of an annular groove, and on the flange of the rack of the annular protrusion, which when installing the shut-off and drain device in the boiler of the tank car enters the above-mentioned ring groove, improves the reliability of the shut-off and drain device tank cars, distortions between the mating parts of the unit, affecting the performance, are reduced to a minimum, which also extends the life of the rubber seal due to uniform wear of the parts.

At the same time, the execution of an annular groove on the surface of the casing, and on the rack flange of the rack, which, when the shut-off and drain device is installed in the boiler of the tank car, enters the aforementioned annular groove made by a precise mechanical method, allows to reduce gaps during assembly of the assembly. Also, the proposed design allows you to refuse to install the lower and upper feathers on the main valve, which reduces the weight of the assembly unit as a whole.

The installation of a limiter between the lower part and the threaded part of the rod, preventing the complete unscrewing of the threaded part of the rod from the rack, allows to reduce the threaded part of the rod and thereby reduce the weight of the rod in the lower part.

Currently, the claimed utility model has developed design documentation and comprehensive testing of prototypes is underway.
