Definitions

  • the invention relates to a protective device for Vorsch spassche for pipeline construction, comprising a plate for covering a partial surface of the Vorsch wide- flange and arranged transversely to this plate insert over which the protective device is detachably connectable to the Vorsch spaflansch, the insert provided with a suspension and connectable via a clamping connection with the Vorsch spaflansch.
  • the present invention has the object to provide a protective device for Vorsch spatsche for pipeline construction, which ensures reliable coverage of the sealing strip in conjunction with an effective and permanent connection to these Vorsch spaflanschen.
  • the plate has on its side facing the flange a centrally extending bead or depression.
  • the plate has on its side facing the flange at least one centrally extending bead or depression.
  • a medium eg. B. Fill grease so that no color pigments can settle on the sealing surface during painting.
  • this bead or depression thus has the task of forming a kind of isolated space on its inside for receiving a medium.
  • the plate is formed corresponding to a provided on the Vorsch spaflansch sealing strip, which is to protect separately during the blasting process against the ingress of contaminants.
  • the arranged transversely to the insert plate extends to the Vorsch experienceflansch the facing side, which can also be referred to as a plug protection device around the hole provided in the flange around. Because the plate is designed and arranged corresponding to this sealing strip, it automatically covers the sealing strip in connection with the measures to be presented later, when the resilient insert is inserted into the flange bore and fixed there by means of a clamping fit.
  • the insert has an at least substantially cylindrical basic shape.
  • the shape and size of this cylinder is dimensioned so that when inserting the insert into the bore of the flange of the corresponding clamping fit is ensured.
  • the protective device is made of a plastic having a density ⁇ 1 kg / m 3 .
  • a dimensionally stable and the loads resistant, advantageously one-piece, jet stopper can be realized, which makes it possible
  • the sealing strip also form-fitting cover to exclude their mechanical damage.
  • the jet plug made of a plastic with a density> 1 kg / m 3 can also withstand any powder coating and the associated heat effect. At the same time, the abrasion during blasting is minimized and it is possible to machine the radiant flange automatically with a blasting system.
  • the insert will have apertures serving as springing, which will result in some compliance of the insert and will ensure the press fit when inserted into the flange bore.
  • the suspension is formed by openings extending parallel to the longitudinal axis of the insert, also to achieve the corresponding compliance.
  • the openings are formed as notches, so make up a kind of recessed triangle in the insert, which extends with its tip towards the plate.
  • a variant of this provides that the openings are formed as slots which extend parallel to the axis of the insert.
  • a certain smoothness is additionally achieved if the openings are formed as rounded slots to prevent breakage or tearing of the plastic.
  • the fillets are also positioned towards the plate in the area of the inserts.
  • the insert is then formed by a plurality of separately arranged clamping clips, which extend individually perpendicular to the plane of the plate. This is the Compliance at the end facing away from the plate of the insert particularly large, in the direction of plate it may decrease. In this way, the use of the landing plug can fix on the flange to a certain extent of itself.
  • clamping clips have bulges on their outer sides, which additionally serve for better fixation.
  • the clamping clips are not formed for this purpose with a constant thickness. Rather, they preferably have in their middle an outwardly inclined curvature, which facilitates the fixing of the insert and thus the jet stopper.
  • clamping clips on their outer sides have the clamping effect improving webs.
  • the actual clamping clasp is therefore at least approximately of constant thickness in this variant, but it is arranged on the outside of the clamping brackets preferably parallel to the plate extending individual webs, which should provide an improvement in the clamping action.
  • the bead extends on the outer edge of the plate, so that as far as possible from the outside forms as much space as possible for receiving such a medium.
  • the plate is provided with several, preferably concentric, preferably with two beads. Also conceivable are eight or more concentric beads. This is on the one hand given an even better variant of a stiffener, on the other hand, here form several chambers for receiving a medium.
  • the jet stopper can also remain in its position as flange protection until it is finally removed at the later site of use.
  • the removal can be done by hand by turning and pulling, better with a pair of pliers or a comparable Tool done, if the plate has on its side facing away from the flange at least one pulling device.
  • this design and arrangement of the plate in addition to use a residue-free removal of the jet plug feasible, so that the sealing strip does not need to be cleaned with solvents or complex mechanical processes.
  • the pulling device is at least one, preferably two oppositely arranged tabs. Ultimately, however, up to 16 serving as a pull tabs are conceivable.
  • FIG. 2 shows a protective device in section
  • FIG. 3 shows an opening in an insert in the form of a slot
  • FIG. 4 shows an opening in an insert in the form of a notch
  • FIG. 5 shows a variant of FIG. 3
  • Figure 6 shows a protective device with clamping clips with buckles
  • Figure 7 shows a clamping device with clamping clips with webs.
  • Vorsch a Vorsch currentflansch 2 is shown having an inner bore 6. It is a part surface 5 on the side 22 of the Vorsch spaflansches 2 in the form of the so-called sealing strip 7 effectively cover against contamination. Among other things, this means that penetration of blasting medium during blasting or painting must be avoided.
  • the protective device 1 is formed in the form of the jet stopper.
  • the insert 3 corresponds to the flange bore 6 (inner diameter) to the effect that the insert 3 and thus the jet stopper 1 fixes itself during insertion due to its flexibility. Openings 9 realize in this embodiment, the suspension 8 to produce this flexibility of the insert 3.
  • the plate 4 has on its side facing the flange 15 in Area of its outer edge 19 an outer bead 17 and further inside a bead 18 on. Between the beads 17, 18 and between the inner bead 18 and the insert 3 is formed in each case a space 23, 24, which may need to be filled with a medium such as grease, so that no color pigments could settle on the sealing surface during painting ,
  • the flange 16 facing away from the pulling devices 20, 20 'in the form of the tabs 21, 21' clearly visible.
  • Preferred diameters of the plate 4 are at least 20 mm and in the case of use 3 at least 10 mm.
  • FIGS. 3, 4 and 5 show three different variants of one
  • FIG. 3 shows an opening 9 in the form of a simple slot 13
  • FIG. 4 shows a notch 12 which tapers in the direction of the plate
  • FIG. 5 shows one with a rounding 14 in order to prevent breakage or tearing of the plastic.
  • FIG. 6 shows a protective device 1 of smaller dimensions with the insert 3, which is formed by a total of six clamping clips, of which three are recognizable and designated by the reference numerals 30, 31, 32. Between the free-standing clamping clips, the slots 45, 46 can be seen. For improved fixation of these clamping clips 30, 31, 32, these are of uneven thickness and have approximately in the middle of their outer sides 34, 35, 36 outwardly inclined bulges 38, 39, 40. 17 is the outer bead and 18 the inner bead. Both are concentric, so they include the gap 23. On the other, the insert 3 side facing away from the plate 4 are two as tabs 21, 21 'trained traction devices 20, 20'. FIG.
  • FIG. 7 shows a somewhat larger protective device 1 in the form of a jet stopper with a total of eight clamping clasps, of which four are identifiable here and designated by the reference numerals 30, 31, 32, 33. These are slits 45, 46, 47 arranged leaving and formed as a particularly suitable clamping device.
  • the clamping brackets 30, 31, 32, 33 on their outer sides 34, 35, 36, 37 webs 41, 42, 43, 44. These webs are arranged parallel to the plate 4 in the direction of the plate 4 opposite end of the clamping clips 30, 31, 32, 33. They stabilize the insert 3 and improve the clamping effect when inserted into the Vorsch spaflansche.
