UA55568C2 - Barrel of tank container - Google Patents

Abstract

A barrel of a tank container includes a case and discharge device that includes an overflow valve, valve seat and discharge pipe oriented along boiler case and partially recessed in lower wall of end side of case with respect to cross section of pipe. At admission of discharge pipe is made a longitudinal transversal bevel on longitudinal part of which is mounted a seat of overflow valve, and transversal parts of bevel of discharge pipe over the seat of overflow valve and under it are closed by walls. The seat of the overflow valve is equipped with barrels fastening lower part of discharge device and contains a groove in which is mounted a gasket on which is located a ring.

Description

The invention relates to containers for storing and transporting liquid products, and is specifically used in the construction of tank containers.

A well-known boiler with a drain device, supplied with a shut-off valve located in the tray. In the same pallet, there is a rack with a nut through which the shut-off valve control rod is passed. The lower part of the draining device is provided with vertical draining nozzles, closed with a plug (see AS USSR 110663, class 20c, 9, 1957).

A boiler with such a draining device in the cross section has an increased overall size in the vertical direction and can be used as a stationary tank or in railway tanks.

A known cylindrical boiler for transporting liquid, gas or bulk material with unloading under the influence of gravity, containing a housing and a draining device, including a drain valve, a drain valve seat and a discharge nozzle, oriented along the boiler body and partially recessed in the bottom wall of the end side body in relation to the cross-section of the nozzle (see USSR patent 1.308.190,

Vb61D 88/12 dated 04/30/87, published in bulletin M16, 1987). Such a boiler in its cross-section in the vertical direction has a minimum overall size and, apparently, can be changed in tank containers, but it does not provide for the installation of an internal shut-off valve with a service handle located in the upper part of the container, which is especially important for safety when draining dangerous loads

The basis of the invention is the task of improving the boiler of a tank container, which ensures the installation of an internal shut-off valve with a service handle located at a safe distance from the discharge nozzle, which ensures the safety of unloading the tank container during draining.

The task is solved by the fact that in the boiler of a tank container containing a housing and a draining device, which includes a drain valve, a seat of a drain valve and a discharge nozzle, oriented along the boiler body and partially recessed in the lower wall of the end side of the body relative to the cross section of the nozzle, respectively before the invention, a longitudinal cross section was made at the inlet of the discharge nozzle, on the longitudinal part of which a seat of the drain valve was installed, and the transverse parts of the section of the discharge nozzle above the seat of the drain valve and below it were closed by walls.

In the variant, the seat of the drain valve is supplied with strikers that secure the lower part of the drain device.

In addition, the seat of the drain valve can be made with a recess in which a gasket is installed, on which the ring is placed.

The cause-and-effect relationship between the set of essential features and the technical result achieved is that thanks to the step cut at the inlet of the discharge nozzle, it became possible to install the seat of the drain valve from the lower part of the drain device placed on it. At the same time, the installation of the control handle at a safe distance from the drain nozzle is ensured.

In addition, the stepped cut on the discharge nozzle allows you to install the valve seat at the level of the lower forming boiler body, which allows you to completely drain the product. And this, in turn, ensures increased reliability, unloading safety during draining, and operational safety of tank container boilers.

The essence of the invention is explained by the drawings, where:

Figure 1 shows a general view of a tank container; in Fig. 2 - remote element A of Fig. 1; in Fig. 3 - the remote element B of Fig. 2; in Fig. 4 - view B in Fig.; in Fig. 5 - a section for installing the saddle at the inlet of the discharge pipe.

The boiler of the tank container contains a cylindrical body 1, which houses a device 2 with an internal drain valve 3, an external shut-off valve 4 with a plug 5, located at the outlet of the discharge nozzle 6. The drain valve C is connected to a screw 7 screwed into the bottom of the cup 8 9, in which windows 10 are made. In the upper part, the draining device 2 contains a shaft 11 with a handle 12 for controlling the draining device 2.

The shaft 11 is sealed with gaskets 13 using covers 14 and connected to the screw 7 using a rod 15.

The discharge nozzle would be oriented along the body 1 of the boiler and partially sunk in relation to its cross-section in its lower part.

The seat 16 of the drain valve C is installed in the wall of the housing 1 at the entrance of the unloading nozzle 6 in the stepped cutout 17, which is made with a longitudinal-transverse section formed by the longitudinal 18 and transverse 19 edges. At the same time, the depth of the cut is chosen in such a way as to ensure the location of the surface 20 of the seat 16 of the drain valve C at the level of the lower forming 21 of the body 1.

The ends of the inlet part of the unloading nozzle 6 above the seat 16 of the drain valve C and below it are closed by walls 22 and 23.

The shape of the cross-section of the unloading nozzle 6 is adopted constructively and can be both oval and cylindrical. The blank for the manufacture of the unloading nozzle b is a tube with the calculated thickness of its wall.

A notch 24 can be made in the seat 16 of the valve Z, in which a gasket 25 is installed, on which a flat ring 26 is placed. The drain valve 3 sits on the ring 26.

This option is used, as a rule, in the production of a boiler from low-alloy or carbon grades of steel. In this case, ring 26 should be made of high-alloy steel.

On the seat 16 of the drain valve C, bonks 27 with threads are placed, to which the cup 9 of the drain device 2 is bolted. The device works as follows.

The opening of the internal drain valve C is carried out by rotating the handle 12 connected to the shaft 11, the force is transmitted to the rod 15 connected to the screw 7, which, unscrewing in relation to the stationary cup 9, - lifts the drain valve C up, and the product through the windows 10 in the cup 9 and the resulting gap between the valve

With and saddle 16 is directed to the outlet through the discharge pipe 6 and the open external shut-off valve 4. In this case, the plug 5 must be removed, and the warehouse communication (not shown in the drawings) must be connected to the discharge pipe 6.

In the event of an emergency (emergency) situation, for example, a product leak at the point of connection of the communication to the discharge nozzle 6, the drain is stopped by the operator, who is at a safe distance from the place of the leak, and in this way possible contact with a dangerous product is excluded. The operator, being away from the place of leakage, has the opportunity to close the drain valve 3. o pennnvnnnt shir a GO
