The invention relates to mechanical engineering and can be applied in the creation of large vessels operating under high pressure for testing instruments and equipment.

The aim of the invention is to increase the reliability of the high-pressure vessel and reduce the cost of its operation by using an axially unloaded lid with a cylindrical insert in which the transverse wall and the lid are mounted, and the space between them is sealed and sealed with their elements and connected to a pressure source.

FIG. Figure 1 shows an over-discharged pressure vessel, a general view; in fig. 2 — node I in FIG. 1, the cut.

The axially unloaded high pressure vessel contains a cylindrical body 1 with two lids 2 located on each side of the body, covering their load frame 3, support elements 4 of the covers made in the form of steel disks, mounted between their bottom and the power frame, and sealing elements 5, 6 and 7. On each side, the vessel has a cylindrical insert 8 installed in a housing with a minimum clearance, on the inner surface of which there are two circular grooves quince, a circular transverse wall 9 mounted in an annular groove a , compression springs 10 installed in a space between a circular transverse wall and a lid formed with a flange inserted into another annular groove (c), the space between the transverse wall 9 and the lid 2 being sealed by means of seals 5, 6 and connected by a pipe 11 to a source pressure 12.

Sealing elements 5 and 6 are installed in the annular grooves of the cylindrical inserts 8 and contact on annular surfaces with circular transverse walls 9 (with the sides of the walls facing the inside of the vessel) and with the flanges of the lids 2 (with the sides of the flanges facing the supporting elements 4), and the sealing elements 7 are mounted on the inner surface of the housing and enclose the cylindrical inserts 8.

Each cylindrical insert 8 consists of three parts e, d, h welded together, which makes it possible to place the wall 9 and the flange of the lid 2 in the annular grooves a t in, after which the parts g and h are welded.

In order to provide the necessary rigidity, the circular transverse walls 9 are provided with ribs 13 intersecting with each other at right angles.

In the circular transverse walls 9, check valves 14 are installed, blocking the outflow of water from the space between the walls 9 and the lids 2 into the vessel, but not preventing the movement of water through them in the opposite direction.

The housing 1 is provided with a shutter 15 locking the hatch for filling the vessel with water at atmospheric pressure, and a pipeline 16 is supplied from the pressure source 12 to the vessel to pressurize water into the vessel up to the calculated pressure.

The cylindrical body is able to perceive significant loads from the pressure of the external environment (water) only in the radial direction. The case diameter is several meters.

The operation of the high pressure vessel is as follows.

A cylindrical body 1 with covers 2 and transverse walls 9 installed in cylindrical inserts 8 is placed in a power frame 3 between supporting elements 4. In the space (on each side of body 1) between covers 2 and transverse walls 9, sealed due to the pressure of the latter elements 5, 6 by force of compressed springs 10, through pipeline 11 from pressure source 12, water is pumped under pressure until its pressure on cylindrical inserts 8 increases their diameters to complete selection of gaps between them and the body and not tight contact will be ensured with the sealing elements 7 (Fig. 2). Then, the shutter 15, which closes the hatch, is opened, and the water is poured through the latter into the vessel until it is filled, after which the shutter is locked. Next, the pipeline 16 from the pressure source 12 injects water into the pressure vessel. When the pressure in the vessel is comparable to the pressure of water in the space between the lids 2 and the walls 9, it begins to enter this space through the check valve 14.

Further injection of water through conduit 16 will increase the pressure both in the vessel and in the space between the lids 2 and the walls 9 until it reaches the specified value and the pressure source 12 is turned off. At the same time, cylindrical inserts 8 due to less rigidity than body 1 will be tightly pressed by water pressure to sealing elements 7, ensuring vessel tightness, and covers 2 will be in close contact with supporting elements 4, transmitting axial force from pressure inside vessel on the power frame 3, while unloading the body 1 of the vessel from the axial load.
