Description

Anordning til sikring av beskyttelseshylser ved forgreninger på Device for securing protective sleeves in case of branches on

vannledningsrør. water supply pipes.

Forgreninger på vannledninger utføres Branches on water mains are carried out

som oftest slik at forgreningsrørets ventilhus ved hjelp av klammer eller liknende most often so that the manifold's valve housing by means of clamps or the like

klemmes fast til hovedledningen, idet ven-tilhusets gjennomstrømningsåpning står i clamped to the main line, with the flow opening of the valve housing standing in

forbindelse med et hull som er boret i hovedledningens vegg. Etter at ledningen har connection with a hole drilled in the wall of the main line. After the cord has

vært i drift en tid, viser det seg ofte at been in operation for some time, it often turns out that

hullet i hovedledningens vegg ruster igjen. the hole in the wall of the main line rusts again.

Når hullet skal renses for rust, medfører When the hole is to be cleaned of rust, entails

dette som oftest store arbeidsomkostnin-ger da ledningen jo vanligvis ligger ned-gravd. Det har derfor vært foreslått å an-bringe en hylse av ikke rustende metall i this usually results in large labor costs as the line is usually buried. It has therefore been proposed to fit a sleeve of non-rusting metal in it

åpningen. Hylsen hvilte mot en brysting the opening. The sleeve rested against a breastplate

i ventilhuset, og dens ene ende gikk inn i in the valve body, and one end of it entered

hullet i hovedledningens vegg. For å sikre the hole in the wall of the main line. To secure

at hylsen ikke gled inn i ventilen, ble den that the sleeve did not slide into the valve, it stayed

bikket ut på hovedledningens innside. Dette medførte flere ulemper. For det første bent out on the inside of the main line. This led to several disadvantages. Firstly

krevde dette et spesielt verktøy og dess-uten var hylsen i veien når hovedledningen skulle renses. this required a special tool and besides, the sleeve was in the way when the main line had to be cleaned.

Anordningen ifølge oppfinnelsen søker The device according to the invention searches

å unngå disse ulemper og skal nå beskrives to avoid these disadvantages and will now be described

under henvisning til vedlagte tegning. with reference to the attached drawing.

På figuren betegner 1 hovedledningen In the figure, 1 denotes the main line

og 2 et ventilhus til hvilket grenledningen and 2 a valve housing to which the branch line

kan kobles. Ventilhuset 2 er festet til hovedledningen på vanlig måte, f. eks. ved can be connected. The valve housing 2 is attached to the main line in the usual way, e.g. by

hjelp av to U-formede bøyler som ikke er using two U-shaped brackets that are not

vist. 3 betegner en elastisk tetningsring. shown. 3 denotes an elastic sealing ring.

På figuren er hylsen 4 vist i den stilling In the figure, the sleeve 4 is shown in that position

den inntar i montert stand, idet denne it takes in the assembled state, as this

med en brysting 6 hviler mot en brysting 7 i ventilhuset 2. På tegningen stikker hylsens 4 ende inn i hovedrøret 1, men for å unngå de foran nevnte ulemper, vil den i praksis lages slik at den ikke stikker in-nenfor rørveggen. Ovenfor hylsen 4 er det i ventilhuset 2 dreiet ut et spor 8. 5 betegner en monteringsdor med en brysting 9 og en styredel 10 som går inn i hylsen 4. En delt, utover fjærende ring 11 som pas-ser inn i sporet 8 er vist under brystingen 9. with a breast piece 6 rests against a breast piece 7 in the valve housing 2. In the drawing, the end of the sleeve 4 sticks into the main pipe 1, but in order to avoid the disadvantages mentioned above, in practice it will be made so that it does not stick inside the pipe wall. Above the sleeve 4, a groove 8 is turned out in the valve housing 2. 5 denotes a mounting mandrel with a breast ring 9 and a guide part 10 which goes into the sleeve 4. A divided, outwardly springing ring 11 which fits into the groove 8 is shown under the breastwork 9.

Man kan altså ved hjelp av doren 5 You can therefore use the mandrel 5

presse hylsen på plass idet ringen 11 under innpressingen er anbrakt mellom brystingen 9 og hylsens 4 ende. Når hylsen 4 er kommet på plass vil samtidig ringen 11 ligge overfor sporet 8 og gå inn i dette og således sikre hylsen 4 mot å gli. press the sleeve into place as the ring 11 is placed between the breast ring 9 and the end of the sleeve 4 during pressing. When the sleeve 4 is in place, the ring 11 will at the same time lie opposite the groove 8 and enter this, thus securing the sleeve 4 against slipping.

Claims

Device for, by branch lines on

water pipe, to secure rust protection sleeves against slipping and where the sleeve on one side rests against a breast in a valve housing, characterized in that a ring springing outwards is placed in a groove (8) in the valve housing (2) at the end of the sleeve (4) ( 11), as the ring (11) is placed between the end of the sleeve (4) and a breast piece (9) on the driving mandrel (5) before the sleeve is driven in, so that the sleeve (4) and the ring (11) are simultaneously brought into place.
