    The present invention relates to a safety pressure relief apparatus comprised of a reverse buckling rupture disk having a concave-convex portion connected to an annular flat flange portion by a curved transition connection and a support member having an annular flat flange portion for engaging the annular flat flange portion of the rupture disk and for supporting the transition connection thereof. The support member includes a cutting edge positioned interiorly of the transition connection and forming an opening in the support member so that when the concave-convex portion of the rupture disk reverses itself, the cutting edge severs the disk whereby a portion thereof passes through the opening in the support member. A bar for catching the severed portion of the disk after it passes through the opening in the support member is attached to the support member.

    54) SAFETY DEVICE
    This invention relates to safety devices designed to protect containers or pipelines from dangerous pressure overloads.
    Safety devices are known that contain a rupture disk with grooves on the surface to form weak points 1.
    When the disk is ruptured, there are no separate start-ups, but when the pressure is slightly exceeded, the hole being closed by the disk does not completely open, or the disks are bent without breaking.
    The closest in technical essence to the present invention is a safety device comprising a rupture disc with a concave portion and an annular flat flange connected by a curved transition joint, a flat support member fastened to the flat flange and a cutting element in the form of knives located on the concave side of the disc , so that after bending the disk in the opposite direction, a part of the rupture disk is pressed in and pressed out into four parts — petals that roll up outward under the action fluid passing through the opening (2,
    The disadvantage of this device is also the incomplete opening of the hole when the device is triggered and the possibility of knife blunting due to corrosion.
    The purpose of the invention is to provide, when the device triggers, the maximum flow area and the capture of the cut down part of the disk.
    This goal is achieved by introducing into the known device a catching bar located along the diameter of the disk and fixed on the inserted annular plate fastened to the side of the supporting element opposite to the disk, while the part of the transition joint at the location of one of the bar ends has a larger p & the curvature than the rest of it, and the supporting element is located with the concave-side of the disk and is made in one piece with the cutting element having an annular serrated
    cutting edge tilted towards the rupture disc.
    In addition, the radius of curvature of the part of the transition joint at the location of one of the ends of the beam is 1.5–2 times the radius of curvature of the rest of the transition joint.
    Catch; bar can be made concave in the direction of the rupture disc.
    Figure 1 shows the device section; on FTSG, 2 - view along arrow A in FIG. FIGS. 3-5 show sequential positions of the device when triggered.
    The device 1 (Figures 1 and 2) contains a rupture disk 2 with a concave-convex part 3 connected to annular flat flange 4 by means of a bent crossing connection 5. The annular flat flange 4 of the disk 2 is fixed to a thin supporting element b, which has an annular flat flange 7 and a round toothed cutting edge 8. The annular flat flanges 7 and 4 of the support element b and i of the disk 2 are of the appropriate size and fastened together, for example, by means of spot welding.
    The cutting edge 8 of the support member 6 extends radially inward from the transition joint 5, which is held by an annular flat flange of the support member 6. In addition, the tooth 9 of the cutting edge 8 is preferably made in the shape of triangles and inclined in the direction and inward of the concave-convex part 3 of the rupture disc. 2 at an angle of about 30-45 °.
    ria to the opposite side of the flange 7 of the support element 6 from the rupture disk 2, the bar 10 departs to grip the cut part 11 of the disk 2. The beam 10 is fixed on a round plate 12 of worm metal, which is fixed on the flange 7 of the support element 6. Moreover, the bar 10 is preferably located at a distance from the support element b and prox: odin on the diameter of the hole formed by cutting edge 1 in a plane parallel to the plane of the flange 7. The beam 10 contains a bent / gripping part 13, vynyKjj H side of which is facing to discontinuous DIS 2, and a pair of pillars 14 fixed at the ends of the gripping part 13 and on the circular plate 12. However, the bar 10 can be fixed directly on the annular flat flange 7 of the support element 6. Also, the special shape of the hole formed in the support element by the cutting edge is not mandatory. edge 8, although preference is given to a round shape.
    As can be seen from FIG. 3, part 15 of curved transitional connection 5 of rupture disk 2 has a larger radius of curvature than the rest of transitional connection 5.
    The device works as follows.
    During operation, disk 2 is compressed. Typically, for a given thickness of the disk 2, the smaller the radius of curvature of the transition joint 5, the greater the resistance of the rupture disk 2 to bending in the opposite direction. Consequently, when triggered, the transition joint 5 moves inwards at the point of the greatest radius of curvature, and after that the direction of the entire concave-convex part 3 changes. When the disk 2 is made with part 15, the process of movement deformation begins in part 15 and passes radially from part 15, which is preferably located near one end of the gripping portion 13 of the beam 10. Consequently, the direction of deformation of the disk 2 runs parallel to the axis of the gripping part 13. In FIG. 3, this direction is indicated by the direction lkoy 16.
    The deformation continues in this direction until part of element 3 / opposite part 15 of transition 5 is cut off by cutting edge 8 of support element b. Thereafter, the cutting of the part 3 continues (Fig. 4) in the opposite direction (along arrow 17), with the last part of the rupture disk 2 being cut near the part 15 of the transition joint 5.
    The cut-off central part of the disk 2 passes through the supporting element 6 and is wound around the gripping part 13 due to the pressure of the outgoing fluid, is balanced and held onto the bruise. / ce 10.
    The transitional connection 5 of the rupture disk 2 has a shape in which the radius of curvature of its part 15 is about 1.5–2 times the radius of curvature of the rest. The length of part 15 of transitional connection 5 varies depending on the size of the rupture disc, but usually ranges from 12 to 18 mm for disks with a diameter of 25 mm and between 25 and 30 mm for disks with a diameter of 130 mm and more,
    The proposed device can be reliably applied in cases where the calculated pressure for rupture of the discs in bending in the opposite direction is significantly lower than the response pressure of devices with explosive discs having grooves to indicate weak points.
