Description

'448 913 2 och att det i ringkantens och kantflänsens övriga radiella område bildas ett mellanrum mellan dessaoch membrankanten, så att alltså inget av den från svetsningen härrörande värmen leds över till membranets kant genom beröringskontakt över en stor yta på detta ställe. 448 913 2 and that in the other radial area of the ring edge and the edge flange a space is formed between these and the membrane edge, so that none of the heat originating from the welding is conducted over to the edge of the membrane by contact contact over a large surface at this place.

Uppfinningen beskrivs i det följande närmare med hänvisning till- ett på ritningen visat utföringsexempel. På ritningen visar fig 1 en schematisk, delvis skuren sidovy av en menbrandämpdosa, fig 2 ett_snitt genom detaljen II i fig 1 i större skala, och fig 3 och 4 en vy av mem- branaämpaoean i pilriktningarna il resp Iv i fig 1.The invention is described in more detail below with reference to an exemplary embodiment shown in the drawing. In the drawing, Fig. 1 shows a schematic, partly cut-away side view of a membrane firebox, Fig. 2 a section through the part II in Fig. 1 on a larger scale, and Figs.

Membrandämpdosan består av metall, t ex stålplåt eller ett rost- fritt och syrabeständigt material, t ex VQA. Den har ett grytformigt hus 10 med inlödd tilloppsstuts 11 och avloppsstuts 12. Grytan är öppen åt vänster. Husets'mantel övergår vid sin öppning i en radiellt utåt ut- skjutande och ungefär vinkelrätt utböjd kantfläns 13. På den öppna sidan är huset 10 i höjd med kantflänsen tillslutet medelst ett böjligt membran 14. Detta membran består t ex av gummi med eller utan inre armering av väv, i varje fall av en elastomer. Membranet 14 är med en.runt om löpande kant 15 fastklämt mot membranets 14 kant 15 med kraftigt, axiellt speci- fikt tryck och pressar kanten 15 stadigt mot husets 10 kantfläns 13; Övriga delar av membranets 14 yta kan svänga fritt.The membrane damping box consists of metal, eg sheet steel or a stainless and acid-resistant material, eg VQA. It has a pot-shaped housing 10 with soldered inlet spout 11 and drain spout 12. The pot is open to the left. At its opening, the housing sheath merges into a radially outwardly projecting and approximately perpendicularly bent edge flange 13. On the open side, the housing 10 is closed at the level of the edge flange by means of a flexible membrane 14. This membrane consists, for example, of rubber with or without inner reinforcement of fabric, in each case of an elastomer. The diaphragm 14 is clamped with a running edge 15 around the edge 15 of the diaphragm 14 with strong, axially specific pressure and presses the edge 15 firmly against the edge flange 13 of the housing 10; Other parts of the surface of the diaphragm 14 can swing freely.

Klämdelen 16 är medelst en kantsvetsfog 18 hopklämningssäkert och deformeringssäkert fast förbunden med huset 10 genom plasmasvetsning eller skyddsgassvetsning, t ex argonbågsvetsning. Svetsfogen 18 ligger på stort axiellt avstånd 3 från kanten 15 och membranets 14 övriga yta, så att den vid svetsningen tillförda värmen avledes innan den kan skada membranet 14. _ Klämdelen 16 består av ett ungefär hattformigt lock 19, varvid ringkaian bildar dess hattbrätte. Lockets centrala del uppvisar en lock- vägg 20, som ligger på axiellt avstånd från membranet 14, och som över en sned mantel 21 övergår i ringkaten 17.The clamping part 16 is by means of an edge welding joint 18 securely clamped and deformed securely connected to the housing 10 by plasma welding or shielding gas welding, for example argon arc welding. The weld joint 18 lies at a large axial distance 3 from the edge 15 and the rest of the surface of the membrane 14, so that the heat supplied during welding is dissipated before it can damage the membrane 14. The clamping part 16 consists of an approximately hat-shaped lid 19, the ring quay forming its hat board. The central part of the lid has a lid wall 20, which is located at an axial distance from the membrane 14, and which passes over an oblique jacket 21 into the ring cat 17.

Huset 10 uppvisar vid sin kantfläns' 13 ytterkant en cylindrisk halsdel 22, vilken omger klämdelen 16 och håller denna centrerad. Locket '19 uppbär vid sin ringkants 17 ytterkant en cylindrisk innerhals 23, som omges av halsdelen 22 och sitter däri t ex medelst skjutpassning eller hellre medelst presspassning. 1 _ I ' Halsdeln 22 och innerhalsen 23 har en betydande axiell utsträckë ning 3. Båda är förbundna som kantfog vid den vänstra axiella änden meaelst xentføgen 18, vilken ner samme nellfastnet som naleaelen 22 och innerhalsen 23. Kantfogen 18 är bildad genom nersmältning av kanten utan svetstillsatsämnen. - 2 _ I lxembranet 14 är lnklämt mellan ringkanten 17 och kantflänsen 13 n,The housing 10 has at its outer edge 13 a cylindrical neck part 22, which surrounds the clamping part 16 and keeps it centered. The lid '19 carries at its outer edge 17 an cylindrical inner neck 23, which is surrounded by the neck part 22 and sits therein, for example by means of a sliding fit or rather by means of a press fit. The neck portion 22 and the inner neck 23 have a significant axial extension 3. Both are connected as an edge joint at the left axial end between the x-joint 18, which down the same nail fastener as the naleale 22 and the inner neck 23. The edge joint 18 is formed by fusing the edge without welding additives. In the membrane 14 is clamped between the ring edge 17 and the edge flange 13 n,

Both ring surfaces 33, 37 are at approximately the same, radial distances and radially as far inwards as possible. Their width amounts to only a fraction of the total width of the edge flange 13 and the ring edge 17, respectively, so that the edge 15 is sandwiched between the edge flange 13 and the ring edge 17 with small contact surfaces only in the area of the ring surfaces 33 and 37, ideally only through line contact. 13 and the ring cat 17 are directed obliquely outwards from the plane of the edge 15 of the diaphragm 15, the surface part abutting the membrane edge 15 forming the respective ring surfaces 33 and 37, respectively. The ring surface 33, which at least to some extent projects axially, can is also formed by a material thickening or deformation of the edge flange 13 or the ring edge 17. During assembly, the membrane 14 is inserted into the housing 10, after which the lid 19 is inserted into the neck part 22 and pressed in such a way that the membrane at its edge 15 is clamped with high specific pressure. Due to the press fit, the lobe 19 remains in this position, so that the edge joint can subsequently achieve 1.
