Description

The utility model relates to the production of pressure vessels, and can be used in the construction of containers for compressed and liquefied gases or liquids, for example, vessels for storing fire extinguishing substances under pressure, fuel tanks for compressed natural gas with a special configuration, etc.

A technical solution is known for a fuse for a gas distribution system, which describes a battery of two high-pressure cylinders operating on one valve [Description of the invention to US patent No. 22244545 of 08/11/1938, Ncl. 222-3, publ. 06/17/1941].

The disadvantage of this solution is the relative complexity of the design, where each cylinder must be equipped with its own set of valves and fittings, and the flexible connection of the cylinders requires their additional rigid fixation.

Known distribution device for combustible gas, which consists of many cylinders united by a single collector [Description of the invention to patent EP No. 0805302 from 05/03/1996, IPC ⁶ F17C 1/00, publ. 11/05/1997]. The locking devices of each cylinder are combined by a system of rigid pipes with access to a single (common) gearbox. Between themselves, the cylinders are combined to form a rigid structure.

The presence of many locking and starting devices makes the design of the battery insufficiently reliable and expensive, and the devices for rigidly fastening the cylinders to each other, which each cylinder is equipped with, makes the design of the cylinder low-tech.

Known type-setting reservoir for liquids or pressurized gases, which includes many single cylinders, united by a manifold system, which are located both from the upper neck of the cylinder, and lower [Description of the invention to PCT application No. 98/26209 from 12/13/1996, IPC ⁶ F17C 1/00, publ. 06/18/1998]. The configuration of the outlines of the typesetting tank can be arbitrary, which is obviously due to the presence of free space where this tank can be placed.

Among the disadvantages of this technical solution can be noted

the difficulty of assembling such a battery, due to the very large number of joints, and low reliability, which is proportional to the number of single welded and threaded joints. Not without reason, the design of the reservoir provides for the presence of a membrane that can eliminate local gas leakage by clogging the neck of a defective cylinder.

Known matching pressure cylinder, consisting of several thin-walled interconnected cylinders, combined using a composite shell in a battery [Description of the invention to US patent No. 5577630 from 02.02.1995, Ncl. 220-581, publ. 11/26/1996].

A single outer shell does not allow to obtain a battery configuration other than planar. In addition, the manufacture of cylinders of this design is notable complexity. In their production requires special unique, and therefore expensive equipment.

Known battery cylinder, made in the form of a set of spherical containers (elements), interconnected through cylindrical rings (flanges), for example, by welding [Description of the invention to A.S. USSR No. 138784 dated 04/08/1960, IPC ⁶ F17C 1/00, publ. 01/01/1961]. In terms of counteracting internal pressure, spherical containers are the most optimal.

The drawback of a cylinder is the specific area of use - pumping and storage stations with a large volume (from 10 ⁵ dm ³ ) of required capacities. In the case of small volumes (10 ² -10 ³ dm ³ ) the production of these battery cylinders is low-tech due to the complexity of their manufacture and non-compact form.

The closest in the set of essential features of the claimed utility model is a welded container (tank) for storing gas under high pressure, consisting of at least two single containers (vessels) having a common partition with a communicating hole, and one unit container is equipped with a fitting (neck) for connection shut-off valves [Description of the invention to patent EP No. 1286103 of July 17, 2002, IPC ⁶ F17C 1/00, publ. 02/26/2003]. Thanks to the sectional structure, the operation of these containers is characterized by a high degree of safety.

Nevertheless, the design of each version of the known welded containers is unique, and the lack of unification makes the product

extremely low-tech and, accordingly, expensive to manufacture.

The problem solved by the utility model is to create the next design of a compact high-pressure vessel with structurally unlimited capacity and arbitrary configuration.

The technical result will be the creation of a special composite tank for compressed and liquefied gases or liquids, designed for high pressure, technologically advanced to manufacture and having a special shape, including one easily adapted to existing layout schemes, as well as the specifics of operation.

To solve the problem and achieve the claimed technical result in a container for compressed and liquefied gases or liquids, containing at least two vessels connected to each other with the possibility of communication, at least one of which is equipped with a neck for connecting shut-off valves, each vessel includes a cylindrical shell and bottoms, while the vessels communicate with each other through the through holes in the side walls of the shells and / or bottoms through at least one tubular connecting th element, through which portions on its outer surface sealingly bonded to the walls of the holes in the shells and / or heads of the vessels.

Besides:

- the walls of the cylindrical shells and / or bottoms in the places of the through holes are made with increased thickness;

- increased wall thickness in the places of the through holes is made in the form of an overlap of cylindrical shells and cylindrical sections of the bottoms;

- increased wall thickness in the places of the through holes is made in the form of an lap ring on a cylindrical shell or on a cylindrical section of the bottom;

- the fastening of the outer sections of the tubular connecting element with the walls of the holes is made welded, or glue, or soldered, or threaded with an adhesive sealing layer.

The utility model is illustrated in the drawing, where:

- figure 1 shows a General view of the container for compressed and liquefied gases or liquids;

- figure 2 is a top view of the tank;

- figure 3 is a variant of the power tight connection of the vessels of the container;

- figure 4 is a view A of figure 3, is a side view of the tubular connecting element;

- figure 5 is a design of the side wall of the vessel in place of the through hole.

The container for compressed and liquefied gases or liquids contains two or more vessels 1 connected to each other with the possibility of communication, at least one of which is equipped with a neck 2 for connecting shut-off and supply valves (not shown conditionally), AT THIS, each vessel 1 includes a cylindrical the shell 3 and the bottoms 4, while the vessels 1 communicate with each other through the through holes 5 in the side walls of the shells 3 and / or bottoms 4 by means of at least one tubular connecting element 6, which through sections 7 on its outer surface 8 is hermetically bonded to the walls of the holes 5 in the shells 3 and / or the bottoms 4 of the vessels 1. The walls of the cylindrical shells 3 and / or bottoms 4 in the places of the through holes 5 are made with an increased thickness, which is obtained, for example, in the form of an overlap of the cylindrical shells 3 and cylindrical sections 9 of the bottom 4 or in the form of an lap ring 10 on the cylindrical shell 3 or on the cylindrical section 9 of the bottom 4.

Power tight fastening of the outer sections 7 of the tubular connecting element 6 with the walls of the holes 5 can be made welded, or glue, or soldered, or threaded with an adhesive sealing layer (not shown conventionally).

Let us analyze the significance of the features of a utility model.

Vessels 1 constituting a container for compressed and liquefied gases or liquids are hermetically connected with each other by means of tubular connecting elements 6, while the walls of the cylindrical shells 3 and / or bottoms 4 in the places of the through holes 5 are made with an increased thickness, which made it possible to provide a single connection elements of the battery (vessels 1) due to welding, soldering, gluing or through the use of appropriate threads (as shown in figures 1 and 3), sealed and fixed in assembled form, for example, special glue. This technical solution allows you to get another design

a special composite large-capacity container, individually adapted to already existing layout schemes, for example, located along the wall, located under the flooring, placed on the roof of a passenger vehicle, repeating in plan the bottom of the trunk of a passenger car, etc.

Existing schemes for arranging cylinders into batteries (see the prior art) also allow one to obtain the above configurations, however, their serial connection with the help of coils and multiple shut-off devices or parallel connection to a common bus may not provide the necessary flow rate of the working medium and is not power. In such schemes, each individual self-sufficient capacity is individually fastened to a common base or a package of cylinders is combined into a certain monolithic structure. In the claimed technical solution, the container for compressed and liquefied gases is a rigid non-separable assembly unit with a minimum number of parts, which provides a high degree of reliability of the device, including due to the absence of excessive mechanical collapsible joints. The fastening of such a design to a certain base, in principle, it is enough to ensure only at one most characteristic point.

The design of containers for compressed and liquefied gases or liquids will be considered in detail on the example of its manufacture. An example is illustrated in FIG. 1 and FIG. 2.

Vessels 1 are manufactured using conventional techniques. One of the vessels 1 has a bottom 4 with a neck 2 for valves and blanks and a blind bottom 4, the other vessels 1 have a blind bottom 4 on each side. At the border of the transition of the bottom 4 to the cylindrical part of each vessel 1, in the place where through holes 5 will be made, which are stress concentrators, lapping (reinforcing) rings 10 are installed, increasing the wall thickness of the vessel 1 to the required value.

In the side wall of the vessel 1 provided with an lap ring 10, for example, two holes 5 are made - opposite or at an angle, for example, 90 ° to each other. In other vessels 1, in places of wall thickness increased by lap rings 5, counter holes 5 are also made. These holes 5 should be so many that, if necessary,

vessel 1 could be connected to another vessel 1 or, conversely, the last vessel 1 in the battery should be closing - not have extra holes 5 for connecting the next vessels 1.

Separately, tubular connecting elements 6 are made, for example, in the form of elongated fittings with multidirectional threaded sections 7 along the edges and a turnkey hexagon 11 in the middle.

The vessel 1 with the neck 2 is installed in the device, for example, is laid on the table and fixed. A second vessel 1 is installed (laid) next to it, each bottom 4 of which is deaf, so that the holes 5 of both vessels 1 are oriented to each other. In both holes 5, for example, a tubular connecting element 6 is simultaneously baited, on the threaded sections 7 of which adhesive sealant is applied. Rotating the tubular connecting element 6 by the hexagon 11 with a wrench, the vessels 1 are brought to a state of hard contact with each other.

In the same way, the third vessel 1 of the battery is assembled, the fourth, and so on, the required amount. Closes the battery vessel 1, which does not have additional holes 5 for connection.

The assembled vessel battery 1 — a container for compressed and liquefied gases or liquids — is maintained until the adhesive composition is fully polymerized. Stop valves are wrapped in the neck 2 and the container is ready for operation.

The capacity is operated as follows. Liquid carbon dioxide is pumped into it under pressure. A filled tank is brought to the place of operation, for example, to a semi-automatic welding section in a CO ₂ medium, installed along the wall of the production section and connected to the automation of the welding equipment. As carbon dioxide is used, the tank is emptied and eventually sent for refueling. Refueling can take place, for example, and in such a way, when, upon the customer’s order, liquid carbon dioxide is brought directly to the place of future use for its intended purpose and it is filled with a vacant tank. The capacity for this should have a sufficiently large capacity to ensure the profitability of on-site refueling.

In the same way, a gas fire extinguishing system based on the aforementioned large capacity tank is operated.

Structurally, a container for compressed and liquefied gases or liquids can also be performed, for example, as follows.

As a tubular connecting element 6, a pipe with a unidirectional thread on its outer surface and a turnkey technological protrusion 12 on its inner surface is used - see Fig. 3 and Fig. 4 (or, for example, a hexagonal profile, a special narrowing of the profile of the passage section and t .d.). The tubular connecting element 6 is lubricated with adhesive and screwed into the hole 5 of the vessel 1 flush. The second vessel 1 is laid next to it. The same adhesive composition is applied to the walls of the connected hole of the second vessel 1. A key is inserted through the through holes 5 in its side walls and inserted into the through hole of the tubular connecting element 6. The connected vessels 1 are brought into contact with lap rings 10, and the tubular connecting element 6 is started to rotate with a key. Having turned the key the set number of times, and having achieved a high-quality connection, it is removed. If necessary, the next connecting element 6 with the applied adhesive composition is screwed into the hole 5 that remains open, the next vessel 1 with the hole 5 previously lubricated with the same adhesive composition is substituted and the assembly process of the next battery vessel 1 is repeated, and so on, the required number of times. The open hole 5 of the last vessel 1 is suppressed with a plug 13, which is also lubricated with an adhesive composition. The advantage of this design is that the vessels 1 are practically adjacent to each other with lap rings 10 - without intermediate parts, such as, for example, in the previous case, hexagon 11 turnkey. In the case of using multidirectional threads on a tubular element 6 with a through hole equipped with turnkey protrusions 12 and assemblies according to the principle described for a tubular element 6 with a turnkey external hexagon 11 (see Fig. 1), a design with guaranteed contact of the lap rings can be obtained 10.

This ensures maximum compactness of the tank and minimum shoulders of possible forces.

After a technologically established holding time, the tank is equipped with shut-off and fittings and can be used for its intended purpose.

In a similar manner, a container is assembled using welding and

soldering unit tanks 1 with smooth tubular elements 6 and smooth (threadless) holes 5. Each of these connection methods has its advantages and disadvantages. Welding and soldering provide guaranteed strength, but require an increase in the size of the tank due to the need to have a greater distance between the lap rings - for the passage of electrodes or a gas burner. In addition, local heating of the surfaces of the vessels 1 to obtain permanent connections may require additional heat treatment to relieve internal temperature stresses, mandatory quality control of the compounds, which will make the product more expensive, and therefore less cost-effective.

A design feature of single vessels 1 may be an embodiment of thickenings for through holes 5 on the side walls. It will be quite technological to perform them in the form of an overlap of cylindrical shells 3 and cylindrical sections 9 of the bottoms 4 - see Fig. 5. This embodiment of the design of single vessels 1 will allow you to get effective in weight and technological capacity.

Among the additional design features of the container for compressed and liquefied gases or liquids, for example, the following can be noted:

- in the container for storing liquids, the vessels must communicate, at least two holes 5 maximally spaced apart in height (as conventionally shown, for example, in FIG. 1);

- to give the tank additional rigidity, it can be equipped with special screeds (clamps) through lodgements (not shown conditionally), etc.

As a result of the solution of this problem, the next design of a special composite tank for compressed and liquefied gases or liquids, designed for high pressure, technologically advanced in production and having an arbitrary shape, with structurally unlimited capacity, including easily adaptable to existing layout schemes, was created, including as well as the specifics of use and operation.
