DK 94 00180 U3DK 94 00180 U3
Den foreliggende frembringelse angår et temperaturfølerhylster .The present invention relates to a temperature sensor housing.
Ved måling af temperaturen for væske- eller gasformige fluida, der befinder sig i eller strømmer gennem rør eller be-5 holdere, anbringes der en temperaturføler således, at den er omsluttet af det fluidum, hvis temperatur skal måles. Dette kan opnås ved, at man fører temperaturføleren ind gennem en boring eller åbning, som er udformet i en rør- eller beholdervæg. Imidlertid skal temperaturføleren beskyttes mod 10 mekanisk overlast, og det skal sikres, at åbningen i røreller beholdervæggen lukkes tæt, så at der ikke trænger fluidum ud fra rør- eller beholdersystemet. Dette kan opnås ved, at man anbringer temperaturføleren i et hylster, der kan have form af et rørformet metallegeme, der er lukket ved sin 15 inderste ende, og som bringes til at ligge tæt an mod et ydre anlæg eller bryst, der omgiver åbningen.When measuring the temperature of liquid or gaseous fluids contained in or flowing through tubes or containers, a temperature sensor is arranged such that it is enclosed by the fluid whose temperature is to be measured. This can be accomplished by passing the temperature sensor through a bore or opening formed in a pipe or container wall. However, the temperature sensor must be protected against mechanical overload, and it must be ensured that the opening in the pipe or container wall is closed tightly so that no fluid from the pipe or container system is penetrated. This can be achieved by placing the temperature sensor in a casing which may be in the form of a tubular metal body, which is closed at its innermost end, which is caused to abut against an outer abutment or chest surrounding the opening.
De mest almindeligt anvendte temperaturfølerhylstre af denne art fremstilles af et metalrørstykke, som formgives således, at den inderste endedel bibringes en formindsket diameter.The most commonly used temperature sensing housings of this kind are made of a metal tube piece which is shaped so as to give a reduced diameter to the inner end portion.
20 Derefter lukkes rørstykkets inderste ende ved hjælp af en metalprop, som langs sin periferi fastsvejses til rørstykkets indervæg, og til den anden ende af rørstykket fastgøres en separat fremstillet, ringformet flange, hvis indre perifere flade fastsvejses til rørstykkets ydre perifere flade. Af 25 sikkerhedsgrunde må fastsvejsningerne ved det således fremstillede temperaturfølerhylster nøje undersøges for lækager.The inner end of the pipe piece is then closed by means of a metal plug which is welded along its periphery to the inner wall of the pipe piece and to the other end of the pipe piece is a separately manufactured annular flange, the inner peripheral surface of which is welded to the outer peripheral surface of the pipe piece. For 25 safety reasons, the welds of the temperature sensor casing thus prepared must be carefully examined for leaks.
Man vil forstå, at det nævnte kendte temperaturfølerhylster er ret kompliceret og derfor forholdsvis dyrt at fremstille. Ved den foreliggende frembringelse er der blevet tilvejebragt 30 et temperaturfølerhylster, som kan fremstilles væsentligt simplere og billigere.It will be appreciated that said known temperature sensor casing is quite complicated and therefore relatively expensive to manufacture. In the present invention, a temperature sensor casing has been provided which can be made substantially simpler and cheaper.
Temperaturfølerhylsteret ifølge frembringelsen er af den ovenfor nævnte art, der er indrettet til at optage en temperaturføler og til at blive indført gennem en åbning i en 2 DK 94 00180 U3 rør- eller beholdervæg, og som omfatter et første rørformet metallegeme, der er lukket ved sin inderste ende, og som ved sin yderste ende har en radial flange beregnet til ved hjælp af fastspændingsorganer fluidumtæt at blive presset mod et på rør- eller beholdervæggen udformet anlæg eller bryst, der omslutter åbningen, og temperaturfølerhylsteret ifølge frembringelsen er ejendommeligt ved, at det rørformede legeme er udformet i ét stykke ved dybtrækning.The temperature sensor casing according to the invention is of the kind mentioned above, adapted to receive a temperature sensor and to be inserted through an opening in a pipe or container wall, and comprising a first tubular metal body closed at its innermost end and having at its outermost end a radial flange intended to be pressurized by means of clamping means fluid-tight against a device or chest formed on the pipe or container wall enclosing the opening, and the temperature sensor casing according to the invention is peculiar tubular body is integrally formed by deep drawing.
Ved at fremstille det rørformede legeme ud fra et enkelt emne ved dybtrækning undgår man at skulle anvende svejsning, og da der ikke er flere dele, som skal forbindes med hinanden, undgår man lækagerisici. Afhængig af længden og øvrige dimensioner af det rørformede legeme og af det materiale, af hvilket det rørformede legeme dybtrækkes, kan dybtrækningen foretages i ét eller flere trin.By manufacturing the tubular body from a single workpiece by deep drawing, welding is avoided, and since there are no more parts to be connected, leakage risks are avoided. Depending on the length and other dimensions of the tubular body and the material from which the tubular body is deep drawn, the deep drawing can be done in one or more steps.
Ofte ønsker man, at det rørformede legeme skal omfatte to længdedele, der hver især har en i hovedsagen konstant inder-diameter, og hvor inderdiameteren for den yderste længdedel er større encl inderdiameteren for den inderste længdedel. I dette tilfælde kan dybtrækningsprocessen foretages i to trin, idet man under det første trin udformer den yderste længdedel og under det næste trin yderligere udformer den inderste længdedel med den mindre inderdiameter. Det er klart, at man om ønsket kan udforme det rørformede legeme med endnu flere længdedele, og inderdiameteren for de enkelte længdedele kan da aftage fra den ene længdedel til den næste i indadgående retning. Der kan mellem de til hinanden grænsende længdedele være udformet en i hovedsagen konisk overgangsdel.Often, the tubular body is desired to comprise two longitudinal portions, each having a substantially constant inner diameter, and the inner diameter of the outermost longitudinal portion being greater than the inner diameter of the innermost longitudinal portion. In this case, the deep drawing process can be performed in two steps, forming the outermost longitudinal portion during the first stage and further forming the innermost longitudinal portion with the smaller inner diameter during the next step. It is clear that, if desired, the tubular body can be formed with even more longitudinal portions, and the inner diameter of the individual longitudinal portions can then decrease from one longitudinal part to the next inwards. A substantially tapered transition portion may be formed between the adjacent longitudinal portions.
Den i temperaturfølerhylsteret anbragte temperaturføler er forbundet med en elektrisk ledning eller leder, der strækker sig ud af hylsteret, og som tjener til at føre målesignaler fra temperaturføleren til et passende registrerings- eller visningsapparat. Temperaturfølerhylsteret kan derfor fordelagtigt omfatte et andet rørformet legeme, der er åbent ved begge ender, og som ved sin inderste ende har en radialThe temperature sensor located in the temperature sensor housing is connected to an electrical wire or conductor extending out of the housing which serves to transmit measurement signals from the temperature sensor to an appropriate recording or display apparatus. Therefore, the temperature sensor housing may advantageously comprise another tubular body which is open at both ends and which has a radial at its inner end.
3 DK 94 00180 U3 flange, der er indrettet til at blive fastspændt mod den radiale flange på det første rørformede legeme ved hjælp af fastspændingsorganerne. Den elektriske ledning kan da føres gennem dette andet rørformede legeme, der tjener til at 5 beskytte og føre ledningen.3 DK 94 00180 U3 flange adapted to be clamped against the radial flange of the first tubular body by means of the clamping means. The electrical wire can then be passed through this second tubular body which serves to protect and guide the wire.
De radiale flanger på henholdsvis det første og det andet rørformede legeme kan være adskilt fra hinanden, idet de blot spændes mod hinanden ved hjælp af fastspændingsorganerne. Ved den foretrukne udførelsesform er de to flanger imidlertid 10 fastgjort til hinanden, fx ved svejsning, som fx kondensatorsvejsning eller punktsvejsning. Denne svejsning tjener kun til at sammenholde temperaturfølerhylsterets dele og behøver ikke at være tæt.The radial flanges of the first and second tubular bodies, respectively, may be spaced apart, simply being tensioned against each other by means of the clamping means. However, in the preferred embodiment, the two flanges 10 are attached to each other, for example by welding, such as capacitor welding or spot welding. This welding serves only to compare the parts of the temperature sensor housing and does not need to be close.
Fastspændingsorganerne kan være af en hvilken som helst art. 15 Ved en foretrukken udførelsesform omfatter de imidlertid en omløbermøtrik, der er indrettet til at blive indskruet i gevind udformet i rør- eller beholdervæggen omkring det nævnte anlæg eller bryst. Åbningen i rør- eller beholdervæggen, det omkringliggende anlæg eller bryst og gevindet kan 20 således være anbragt koaksialt.The clamping means may be of any kind. However, in a preferred embodiment, they comprise a threaded nut adapted to be screwed into threads formed in the pipe or container wall around said abutment or chest. Thus, the opening in the pipe or container wall, the surrounding abutment or chest and the thread may be coaxially disposed.
Temperaturfølerhylsterets dele kan være fremstillet af et hvilket som helst egnet metal. For at undgå korrosionsrisici er i det mindste det første rørformede legeme, der kommer i berøring med det i røret eller beholderen værende fluidum, og 25 fortrinsvis også det andet rørformede legeme fortrinsvis fremstillet af rustfrit stål.The parts of the temperature sensor casing may be made of any suitable metal. To avoid the risk of corrosion, at least the first tubular body which contacts the fluid in the tube or container and preferably the second tubular body is preferably made of stainless steel.
Frembringelsen vil i det følgende blive nærmere forklaret under henvisning til tegningen, der viser en foretrukken udførelsesform for temperaturfølerhylsteret ifølge frembrin-30 gelsen, der er monteret i en rør- eller beholdervæg, og som optager en temperaturføler.The invention will be explained in more detail below with reference to the drawing, which shows a preferred embodiment of the temperature sensor housing according to the invention, which is mounted in a pipe or container wall and which accommodates a temperature sensor.
På tegningen er der vist en rør- eller beholdervæg 10, der fx kan udgøre en del af et rør eller en beholder, som indeholder 4 DK 94 00180 U3 varmt vand eller varm damp, og som fx kan være en del af et centralvarme- eller fjernvarmesystem. Det er klart, at der også kan være tale om rør- og beholdersystemer, der indeholder andre former for gas eller væske, og som fx anvendes i industrianlæg. I rør- eller beholdervæggen 10 er der udformet en gennemgående boring 11. Den yderste del af boringen har en større diameter end den inderste del af boringen således, at der mellem de to dele dannes et udefter vendende ringformet anlæg eller bryst 12. I boringen 11 er der monteret et temperatur følerhylster , som omfatter et inderste rørformet legeme 13, der ved dybtrækning er fremstillet af metal, fortrinsvis rustfrit stål. Det inderste rørformede legeme 13 er lukket ved sin inderste ende 14, medens det ved sin yderste ende har en radial flange 15. Det inderste rørformede legeme 13 har en yderste længdedel 16 og en inderste længdedel 17, som har en mindre inderdiameter end den yderste længdedel 16, og de to længedele 16 og 17 går over i hinanden via en konisk forbindelsesdel 18.In the drawing, there is shown a pipe or container wall 10, which may, for example, form part of a pipe or container containing hot water or hot steam, and which may, for example, be part of a central heating or district heating system. It is clear that there may also be pipe and container systems containing other forms of gas or liquid and which are used, for example, in industrial plants. In the tubular or container wall 10 a through bore 11. An outer part of the bore has a larger diameter than the inner part of the bore such that an outwardly annular abutment or chest 12 is formed between the two parts. In the bore 11 For example, a temperature sensing sleeve is mounted which comprises an inner tubular body 13, which is made by deep drawing of metal, preferably stainless steel. The inner tubular body 13 is closed at its inner end 14, while at its outer end has a radial flange 15. The inner tubular body 13 has an outer longitudinal portion 16 and an inner longitudinal portion 17 which has a smaller inner diameter than the outer longitudinal portion. 16, and the two longitudinal portions 16 and 17 interconnect via a tapered connecting portion 18.
Temperaturfølerhylsteret omfatter endvidere en anden rørformet del 19, der ved sin inderste ende har en radialt udadra-gende flange 20, som ligger an mod og fx ved punktsvejsning eller kondensatorsvejsning er forbundet med den ringformede flange 15. Den yderste del af boringen 11 er forsynet med indvendigt gevind, i hvilket der er indskruet en omløbermøtrik 21, der omslutter den rørformede del 19. Ved fastspænding af omløbermøtrikken 21 presses de to flanger 15 og 20 i retning mod det ringformede bryst 12, hvorved en mellem flangen 15 og brystet 12 beliggende tætningsring 22 sammenpresses og danner den fornødne tætning. Omløbermøtrikken 21 kan sikres i sin fastspændte tilstand ved hjælp af en plomberingstråd eller et andet fastlåsningsorgan, som kan indføres gennem en boring 23 i omløbermøtrikken.The temperature sensor housing further comprises a second tubular portion 19 having at its innermost end a radially outwardly extending flange 20 which abuts and, for example, by spot welding or capacitor welding, is connected to the annular flange 15. The outer part of the bore 11 is provided with internal thread, in which is screwed a screw nut 21 which encloses the tubular member 19. By tightening the screw nut 21, the two flanges 15 and 20 are pressed in the direction of the annular breast 12, whereby a sealing ring 22 located between the flange 15 and the chest 12 compressed to form the necessary seal. The nut of the nut 21 can be secured in its clamped state by means of a sealing thread or other locking means which can be inserted through a bore 23 in the nut of the nut.
En temperaturføler 24 er anbragt i temperaturfølerhylsterets inderste længdedel 17, og temperaturføleren har fortrinsvis en yderdiameter, der svarer til længdedelen 17's inderdiameter, så at temperaturføleren 24 og længdedelen 17 er i godA temperature sensor 24 is disposed in the inner longitudinal portion 17 of the temperature sensor casing, and the temperature sensor preferably has an outer diameter corresponding to the inner diameter of the longitudinal portion 17 so that the temperature sensor 24 and the longitudinal portion 17 are in good condition.
