Description
501 375 Luftninq av och provtaqninq pa installerade och vätskefyllda . röranläqqningar och behallare. 501 375 Aeration of and sampling of installed and liquid-filled. pipe installations and containers.
Det förekommer ofta att t.ex. rörsystem i efterhand befinnes ha partier där luft ansamlas, och inte kan avlägsnas utan att en anordning ¥ör luftning anbringas. Hed dagens teknik erfordras aterigen att anläggningen helt eller delvis tappas pa vätska och att en rörstos eller dylikt anbringas.It often happens that e.g. pipe systems are subsequently found to have sections where air accumulates, and cannot be removed without a device for aeration being fitted. With today's technology, it is again required that the plant be completely or partially drained of liquid and that a pipe socket or the like be fitted.

Eøecifik beskrivning av uppfinningen Q. Uppfinningen bestär i huvudsak av en ihalig gängad cylinder med en oorrande och en gängande ëramre del šörsedd med huvud för cylindens vridning med ett verktyg. <2 id vridning av cylindern borras ett hal i vägg n som kan utgöras 0.' e v ett rör eller en vägg till en behallare varefter i direkt {öljd Cl en gängande delen skär en gänga töre det att den gängande delen isšruv as till cylinderns anslag mot dess huvud. Vid gängans ända mot cylinderns huvud kan tätningsring av lämpligt material anbringas.Specific description of the invention Q. The invention consists essentially of a hollow threaded cylinder with a non-contacting and a threaded outer part provided with a head for rotating the cylinder with a tool. <2 id rotation of the cylinder a hole is drilled in wall n which can be 0. ' e v a pipe or a wall to a container, after which in direct {öljd Cl a threaded part cuts a thread törre that the threaded part isšruv as to the stop of the cylinder against its head. At the end of the thread against the head of the cylinder, a sealing ring of suitable material can be applied.
När cylindern igängats kan mätdon šör temperatur appliceras i den ihaliga delen av cylindern. f - 1 ânordningen framgar av figur 1.Once the cylinder has been started, temperature sensors can be applied to the hollow part of the cylinder. The f - 1 arrangement is shown in Figure 1.
B. För mätning av tryck i rörledning eller behallare utvidgas Jppíinningen med att den gangande cylindern förses med ett hal i väggen mot vätskan och att cyïinderns ihaliga del vid dess huvud förses med t.ex invändig gänga där en lämplig anordning för 501 375 anslutning till mätdon för t.ex tryck kan appliceras. Se Figur 2.B. For measuring pressure in a pipeline or container, the connection is extended by providing the walking cylinder with a hollow in the wall against the liquid and by providing the hollow part of the cylinder at its head with, for example, an internal thread where a suitable device for 501 375 connection to measuring devices for eg pressure can be applied. See Figure 2.
Anordningen medför da möjlighet att mäta bade statiskt vätsketryck och totaltryck ( = statiskt + dynamiskt tryck ). Därigenom uppkommer ocksa möjligheten att mäta det strömmande mediets hastighet, jämför pitotrörets princip, genom att rikta mäthalet 'antingen mot vätskans strömmningsriktning eller tvärs densamma.The device then provides the opportunity to measure both static fluid pressure and total pressure (= static + dynamic pressure). Thereby also arises the possibility of measuring the speed of the flowing medium, compare the principle of the pitot tube, by directing the measuring tail 'either towards the direction of flow of the liquid or across it.
'C. För luítning av rörledning eller behallare utvidgas uppfinningen med att den gängade cylindern förses med hal i cylinderväggen placerade sa att hälen efter att den gängade .cylindern iskruvats, befinner sig nära eller intill den inre ytan av rörets eller behallarens vägg varvid det ¥örutsätts att den gängade cylindern placerats pa rörledningens eller behallarens högsta punkt, där luft samlas av fysikaliska förhallanden.'C. For the closure of a pipeline or container, the invention is extended by providing the threaded cylinder with a hollow in the cylinder wall placed so that the heel, after the threaded cylinder has been screwed, is near or adjacent the inner surface of the pipe or container wall, provided that the threaded the cylinder is placed at the highest point of the pipeline or container, where air is collected by physical conditions.
Praktiska synpunkter och konsekvenser Anordningen ovan i sitt grundutförande medëör att vid borrning och gängning uppstar en otäthet dels vid borrspetsens genomträngning av rör eller behallarväggen. Under gängningsfasen erhalles en eller flera sma kanaler varigenom den inneslutna vätskan kan tränga ut och bilda ett läckage under gängnings¥asen. Detta fläckage kan dock vara en fördel eftersom span fran borrning och gängning da transporteras bort med läckströmmen, och därmed hindrar att span och skärrester kommer in i vätskan och därifran törflyttas och eventuellt kan förorsaka olägenheter i andra delar av det system där anordningen används. I installationer där högre tryck rader och där eventuellt vätskan kan vara av sadan art att läckage inte kan accepteras utvidgas upp+inningen med en större tätningsring som är gjord av ett Flexibelt material med ett hal motsvarande kärndiametern i den gängade cylindern och som sappliceras töre applikationen av mätsonden. Denna tätningsring appliceras pa röret eller behallaren med hjälp av limning eller självhäëtande ämne. Tätningsringen används sasom en tätning under borrnings och gängningsfasen och är ocksa försedd med en halighet närmast rör eller behallarväggen för uppsamling av borr och gängspan se -Figur 5.Practical views and consequences The device above, in its basic design, means that a leak occurs during drilling and threading, partly during the penetration of the pipe or the container wall by the drill bit. During the threading phase, one or more small channels are obtained through which the entrapped liquid can penetrate and form a leak during the threading phase. However, this staining can be an advantage because chips from drilling and threading are then transported away with the leakage current, and thus prevent chips and cutting residues from entering the liquid and from there dry-moving and possibly causing inconvenience in other parts of the system where the device is used. In installations where higher pressure lines and where possibly the liquid may be of such a nature that leakage can not be accepted, the inlet is expanded with a larger sealing ring made of a Flexible material with a hollow corresponding to the core diameter of the threaded cylinder and applied to the application of the measuring probe. This sealing ring is applied to the pipe or container by means of gluing or self-heating substance. The sealing ring is used as a seal during the drilling and threading phase and is also provided with a cavity closest to the pipe or the container wall for collecting drills and threads, see -Figure 5.
