Description

-459 202 av det inledningsvis nämnda slaget, vilken är enkel och tillförlitlig. -459 202 of the kind mentioned in the introduction, which is simple and reliable.

Enligt uppfinningen utmärkes en sådan anslutning i första hand av att linern sträcker sig axiellt in i det nämnda loppet , anslutande sig till dess yta , varvid linern avslutas med ett rotationssymmetriskt första säte tvärs loppets axiella utsträckning, varvid gavelstycket är försett med organ för att så axiellt fixzera etl anslutningsrör, försett med ett rotationssymmetriskt andra säte tvärs dess axíella utsträckning, relativt gavelstycket, att de nämnda sätena, företrädesvis med en mel- lanliggande relativt elastisk packning, tätar mot varandra.According to the invention, such a connection is characterized primarily by the liner extending axially into the said barrel, adjoining its surface, the liner ending with a rotationally symmetrical first seat across the axial extent of the barrel, the end piece being provided with means for so axially fixing a connecting tube, provided with a rotationally symmetrical second seat across its axial extent, relative to the end piece, so that the said seats, preferably with an intermediate relatively elastic gasket, seal against each other.

I en föredragen utföringsform av uppfinningen består det nämnda organet för fixering av med varandra samverkande gängor, anordnade dels i det nämnda loppet och dels på anslutningsrörets yttre yta.In a preferred embodiment of the invention, the said means for fixing threads cooperating with each other, arranged partly in the said passage and partly on the outer surface of the connecting pipe.

Sätena kan ha olika utformning. Så kan det första sätet vara plant, me- dan det andra sätet är försett med ett försänkt spår, i vilket en elastisk 0-ring är placerad.The seats can have different designs. Thus, the first seat can be flat, while the second seat is provided with a recessed groove, in which an elastic O-ring is placed.

Uppfinningen framgår av den bifogade figuren, som visar ett längdsnitt genom en del av ett tryckkärl av kompositmaterial med liner av termo- plast ochen anslutning-enligt uppfinningen. En liner av polypropylen betecknas med 1, och det därpå lindade kompositmaterialet, d.v.s. glas- fiber i en matris av epoxiplast med 2. Ett gavelstycke 3, utvändigt försett med utskott i form av såväl höger- som vänstergängor 4 är in- bakat i kompositmaterialet. Gavelstycket 3 är utformat med ett inre axiellt lopp 5, vilket är gängat med gängor 6. Linern 1 sträcker sig med en del 7 ett stycke in i loppet 5, anslutande sig till gavel- Y styckets gängor 6 i dess lopp 5. Linern avslutas med en plan yta 8 vil- ken utgör ett första säte. gänga 10 Ett anslutningsrör 9, försett med yttre , är inskruvat i loppet 5, varvid sålunda gängorna 6 samverkar med gängorna 10. Anslutningsröret avslutas med ett andra säte 11 tvärs dess axiella utsträckning. Detta säte 11 är utformat med ett försänkt spår 12, i vilket en relativt elastisk D- ningsröret 9 är iskruvat så långt ring 13 är placrad. Anslut- , att säker tätning erhålles mellan de En tillverkningsteknisk fördel med anslut- ningen enligt uppfinningen är, nämnda säterna 8 och 11. att det första sätet lätt kan justeras till plan form, eller annan önskad form, tvärs loppet 5, sedan fiber- materialet har lindats på stomdelen.The invention appears from the attached figure, which shows a longitudinal section through a part of a pressure vessel of composite material with liner of thermoplastic and a connection according to the invention. A polypropylene liner is denoted by 1, and the composite material wound thereon, i.e. fiberglass in an epoxy plastic matrix with 2. A gable piece 3, externally provided with projections in the form of both right- and left-hand threads 4, is embedded in the composite material. The end piece 3 is formed with an inner axial bore 5, which is threaded with threads 6. The liner 1 extends with a part 7 a distance into the bore 5, connecting to the threads 6 of the end piece Y in its bore 5. The liner ends with a flat surface 8 which constitutes a first seat. thread 10 A connecting pipe 9, provided with an exterior, is screwed into the bore 5, the threads 6 thus cooperating with the threads 10. The connecting pipe is terminated with a second seat 11 across its axial extent. This seat 11 is formed with a recessed groove 12, in which a relatively elastic D-tube 9 is screwed in as far as ring 13 is placed. Connection, that a secure seal is obtained between the A manufacturing technical advantage of the connection according to the invention is, said seats 8 and 11. that the first seat can be easily adjusted to a flat shape, or other desired shape, across the barrel 5, then the fibrous material has been wound on the body part.
