    A sealable pressure vessel (5) has a closure member (8) held on by means of a bayonet fixing member which is movable between two positions while retaining the mechanical linkage between the vessel (5) and the closure member (8) forming a container (1). The bayonet fixing comprises a vessel lug (18) which co-operates with a stepped slot (17) in a locking ring (9) secured to the closure member (8). In one position of the lug (18) in the slot (17) the closure member (8) is sealed on the vessel (5) and the container is closed to atmosphere while in another position the seal is broken and the container is open to atmosphere. The closure member (8) incorporates a sliding valve (29) which has a spring urged piston (31) carrying a locking pin (32) to lock the lug (18) within the slot (17) when the container is closed to atmosphere. The piston (31) can vent the container to atmosphere when the closure member (8) is sealed to the vessel (5) if the piston (31) is raised since it then connects the interior of the container to atmosphere via a chamber (47) and two ports (48) and (52). Raising the piston (31) disengages the locking pin (32) from the lug (18) so that the closure member (8) can be removed from the vessel (5).

    one
    The invention relates to fluid containers, in particular, comprising a device for depressurization between the locking element and the vessel before releasing the locking element from the vessel. A fluid transportation system, such as natural gas pipelines, includes many devices, such as filters, cyclone devices, separators, and the like, that need access for maintenance and for similar purposes. These devices are mounted in sealed containers with closures that can be removed if desired.
    When the locking element is removed, the fluid may with explosive force drop the locking element from the container.
    The purpose of the invention is to ensure the safety of operation of the device
    Figure 1 shows schematically an adjustment valve for a gas pipeline mounted in a device shown by a contour line; figure 2 - node 1 in figure 1 on an enlarged scale; fig.Z - the same, isometric; 4 is a step notch, an isometric projection.
    Fig. 1 shows a gas pipeline with an inlet pipe 1 and an exhaust pipe 2 connected by means of isolating valves 3 and 4 to the capacity of the pressure vessel 5.
    A device for storing and transporting a fluid may be used with a valve, filter or cyclone device (not shown).
    The container 5 of the device for storing and transporting fluid (pressure suction) is provided with a removable element 6 attached to it by means of a retaining ring 7.
    The locking element 6 depicted in FIGS. 1 and 2 is made with the flange 8 outwardly directed at its lower end to fit on the upper edge 9 of the device. The flange 8 of the locking element is provided with a lower circumferential recess 10, into which the sealing ring 11 is made of a suitable elastomeric material, for example nonprene or similar material, the ring 11 using

    it rests on the upper edge 9 of the vessel 5. The locking element 6 is shaped like a round plate 12 and may include a filling valve going inward
    5 vessels.
    The lower part 13 of the locking ring 7 contains the lower part 14, extending radially outward and welded to the vertical wall 15 of the locking
    10 elements 6.
    As shown in figures 2-4, the stepped groove 17 is made in the outer lower part 14 of the retaining ring 7 and, together with the square height 15, forms a radially outward 16
    inward from the upper end of the vessel 5, the bayonet connection element and the two-position mechanical connection for the locking element 6 and the device. The groove 17 is formed between adjacent stepped surfaces in the retaining ring. The bottom surface of the groove contains two horizontal steps 18 and 19, adjacent respectively to two vertical surfaces 20 and 21. When using the device, the protrusion 1-6 may rest on the steps 22 and 23. When positioned at the bottom level 22, the gauge between the locking element 6 and the container 5 is broken and the internal cavity of the latter communicates with the atmosphere. The protrusion 16 can also be supported on the upper stage 23.
    35 In this position, the locking element 6 is completely closed on the vessel 5, which provides a seal between the locking element 6 and the vessel 5, the container is disconnected from the atmosphere.
    40 Surfaces 24 and 20 form an inlet channel for a protrusion at the lower end of the locking ring 7, the groove 17 is blocked by a vertical surface 25 adjacent to the horizontal surfaces 23 and 19. The protrusion 16 has a configuration that remains between surfaces 23 and 19 when pressed to the surface 26 (see fig. 3). As shown in figure 4,
    50 retaining ring 9 may contain several such grooves 17, and the device may contain the same number of corresponding protrusions 26.
    On the locking element, a valve 27 is mounted, comprising a cylinder 28 formed by a vertical wall 15 and a flange 8 of the locking element 6, and a continuation 29
    wall 15 and flange 8. The cylinder 28 thus formed enters slidably with a cylindrical piston-shaped plunger 30, from which a cylindrical locking pin 31 extends, acting as a latch for locking the protrusion 16 in position at the upper notch 23 of the groove (see Fig. 3) . The device may have several such valves 27 and locking pins 1 to 31, respectively, according to the number of projections 16 and notches 17).
    At the upper end of the plunger 30 there is a cylindrical recess 18, on the end 32 of which rests the lower end of the spiral spring 33. The upper end of the spiral spring 33 rests on the upper wall 34 of the cylinder and, when using the device, can push the plunger 30 down to its upper shoulder 35 the flange 8. In this position, the locking pin 31 passes through the hole 36 made in the flange 8 and stops exactly above the stepped surface 23. If the locking element 6 completely closes the device, the protrusion 16 is ITS into the position illustrated in fig.Z and Stif locking protrusion 31 is aligned with the rear wall 16, blocking it in place. This prevents accidental rotation of the locking element 6 when it is in the fully closed position on the vessel 5. I
    The plunger 30 has two pairs of circumferential circumferential ribs 37 and 38 and 39 and 40 at each of its ends, with a cutout for each o-ring 41 and 42, respectively, made of a suitable elastic material, for example, nitrile rubber. . The 0-rings 41 and 42 provide a gas-tight seal between the plunger 30 and the cylinder 28. The diameter of the central cross section 43 of the plunger 30 is smaller than the diameter of the other sections. Thus, a sealed annular chamber 44 is formed between the 0-shaped rings 4I and 42. are provided with a ventilation window 45 enabling the cylinder 28 to communicate with the internal cavity of the vessel. Air vent 45 so12320. four
    it holds a horizontal portion 46 communicating with the cylinder 28 and a vertical portion 47 communicating with the internal cavity of the vessel. The vertical 5 on the wall 48 of the cylinder 28 is also provided with a ventilation window 49 displaced vertically from the window 46 to allow the cylinder 28 to communicate with the atmosphere.
    10 With the locked closed) position shown in FIGS. 1-4, the windows 45 and 49 are insulated from each other by a seal forming the upper 0-ring 41. However
    15, with the unlocked (open) position, the vent holes 45 and 49 can communicate with each other by means of the chamber 44. In this case, the shutter plunger 30 rises, preliminarily, the fractional influence of the spring 33, until the moment when both vent openings 45 and 49 are between 0-rings 41 and 42, whereby windows 45 and 49 communicate between
    25 by means of camera 44,
    In order to allow the plunger 30 to be raised, it is provided with a drive pin 50 with a threaded end 5 screwed into a hole made at the end of the notch and with a body 52 passing through the hole 53 in the upper wall 34 of the cylinder 28. A spring .33 surrounds the body 52 pin 50 whose head 54 is out
    35 of cylinder 28, allowing the pin 50 to be gripped by hand for actuation. The device can be used several valves 27, one for each
    0 a groove or one for each chamber under pressure, in the presence of separable chambers in the vessel, although to block the locking element 6 on the vessel 5 ne, only one valve 27 is bypassed.
    In order to position and seal the locking element 6 on the container 5, the locking pin 31 is raised by raising the plunger 30. The locking element 6, together with the locking pin 8 and the sealing ring 11, is placed on the lid on the vessel 5 so that the protrusion 16 (or the projections enter input
    55 the channel (s) of the groove 17. (or the grooves for alignment with the horizontal surface 18. The locking element 6 is rotated accordingly, and then pushing the protrusion 16 into the surface 19 until it stops and rotate further until the projection 16 takes the position shown in FIG. 3 and not on the surface 23 of the groove 17. Then the locking element 6 is sealed against the vessel 5 and the plunger 30 is lowered so that the locking pin 31 is aligned with the wall of the protrusion 16 to block the locking element and prevent its accidental rotation and vessel 5.
    To release the locking element 6, the drive pin 50 of the plunger 30 is raised before the occurrence of the connection between the windows 45 and 49 by means of the chamber 44. As a result, the pressure in the vessel is in communication with the atmosphere.
    The locking element is then rotated to its second, partially closed position when the protrusion 16 extends into the surface 21, and then is raised so that the protrusion 16 abuts against the surfaces 22 and 23, and the locking element 6 and the vessel 5 remain mechanically connected. Then, the locking element 6 is turned until the protrusion 16 meets the surface 25 and then comes out of the groove 17,
    The connection of the protrusion-step groove or the valve device into the container allows the valve element to be removed from the vessel with the minimum risk of the element being thrown away by the pressure of the fluid in the container. This is due to the fact that each of these devices provides the ability to release pressure.
    inside the container when the closure remains mechanically connected to the vessel. The container shown in FIGS. 1-4 includes both devices; in this case, the increase in safety is ensured by both the protrusion device and the stepped groove, as well as the valve device with a simple
    A bayonet joint system, for complete safety, it is recommended that both devices be included in a fluid container. This provides pressure release while weakening
    locking devices, and in the case of preservation of some pressure, the device protrusion - stepped groove provides for its automatic lowering during rotation in order to remove the grip before mechanical separation of the latch. In order to facilitate the separation of the locking element, the mating surfaces of the protrusions and grooves may be bevelled, rather than
    perpendicular to the direction of movement of the release;
    When using the proposed device it is impossible to remove the locking element while the pressure inside
     : the vessel is not lowered to atmospheric .. In addition, the alignment of the valve stopper with the vessel discharge eliminates the possibility of turning the locking element relative to the vessel until the stopper is not separated from the protrusion. Continuing engagement of the protrusion with the groove. After releasing the valve stopper, it prevents the locking element from being violently released from the vessel.
    The invention ensures the safety of operation, as it excludes the power dropping of the locking element.
