Opfindelsen angâr et armatur for en termostatventil, med et hus, som har en indbygningsstuds, i hvis forlængelse der er en til en tilslutning forende, cylindrisk boring og derimel-lem et med mindst en yderligere tilslutning forbundet kam-5 mer, og med en ventilindsats til fastgorelse pâ indbygnings-studsen, som med en indre del griber ind i indbygningsstud-sen, pâ en ydre del bærer en koblingsindretning til fastgo-relse af en termostatopsats og er inddelt i en skaftbærer og en sædebærer, som ved en rorforlængelse har et med en om-10 kredstætning forsynet tætningshoved til indgreb i den cylin-driske boring, især for pladeradiatorventiler.The invention relates to a luminaire for a thermostat valve, with a housing having a built-in nozzle, in the extension of which there is a connecting end, a cylindrical bore and also a chamber connected with at least one further connection, and with a valve insert. for fixing to the built-in spigot which interacts with the internal spigot on the outer spigot, carries on an outer part a coupling device for fixing a thermostat set and is divided into a shaft carrier and a seat carrier which, with a rudder extension, has a a circular seal provided with sealing head for engagement in the cylindrical bore, especially for plate radiator valves.
Et sâdant armatur er kendt fra(DE-AS 25 27 132). Der er der beskrevet en termostatventil, hvis hus er anbragt mellem to pladeradiatorer, og hvis indbygningsstuds, der strækker sig 15 horisontalt, slutter inden for begrænsningen af radiatorer-ne. Den lukkestykket bærende skaftbærer er skruet ind i sæ-debæreren. Sædebæreren er ved hjælp af en omlobermotrik fastgjort pâ indbygningsstudsen, rager frem udadtil over pladeradiatorernes endeside og har pâ dette sted koblings-20 indretningen til fastgorelse af termostatopsatsen. Omlober-motrikken trykker et anslag af sædebæreren mod indbygnings-studsens endeflade under mellemkobling af en tætning, hvor-ved sædebærerens aksialstilling er fastlagt. Den aksiale længde af den cylindriske boring overstiger kun ubetydeligt 25 den aksiale længde af tætningshovedet af sædebærerens ror-forlængelse; herved kan der tages hensyn til ved indbygnin-gen optrædende tolerancer. Anvendelsen af en sâdan af sædebærer og skaftbærer bestâende ventilindsats har den fordel, at huset kun har behov for en grov bearbejdning (gevind, ak-30 sialboring), mens aile en præcisionsbearbejdning krævende dele er samlet i ventilindsatsen. Derfor kan fx ventilhuset allerede ved fremstillingen af radiatorerne pâsvejses disse, mens ventilindsatsen f0rst indbygges efter radiatorernes montage.Such a luminaire is known from (DE-AS 25 27 132). There is disclosed a thermostat valve whose housing is arranged between two plate radiators and whose built-in plug extending 15 horizontally ends within the confines of the radiators. The closure bearing shaft carrier is screwed into the soap debarker. The seat carrier is secured to the recess nozzle by means of an orbital nut, protrudes outwardly over the end side of the plate radiators and at this location has the coupling device for fixing the thermostat set. The omlober counter pressure pushes an impact of the seat support against the end surface of the recessed studs while interconnecting a seal whereby the seat support axial position is determined. The axial length of the cylindrical bore exceeds only slightly the axial length of the sealing head of the seat carrier rudder extension; in this way, tolerances that occur during insertion can be taken into account. The use of such a seat bearing and shaft bearing permanent valve insert has the advantage that the housing only needs a rough machining (thread, axial bore), while all precision machining parts are required in the valve insert. Therefore, for example, the valve body can already be welded during the manufacture of the radiators, while the valve insert is first incorporated after the radiators are installed.

Det er ogsâ allerede kendt (DE-AS 23 11 080) at indsætte skaftbæreren direkte i husets indbygningsstuds og at anbrin-ge koblingsindretningen pâ huset. Herved er imidlertid ven-tilsædet anbragt i huset, sâledes at en finbearbejdning af 5 huset er uundgâelig.It is also already known (DE-AS 23 11 080) to insert the shaft carrier directly into the housing of the housing and to place the coupling device on the housing. Hereby, however, the friend seat is placed in the housing, so that a fine machining of the housing is unavoidable.
Det er endvidere kendt (DE-PS 22 53 462) at adskille sædebæ-reren fra skaftbæreren med det formâl at indstille kv-værdi-en, hvorved en koblingsindretningen bærende ring over et ud-vendigt gevind er i indgreb med indbygningsstudsen, belaster 10 skaftbæreren aksialt og denne trykker sædebæreren mod en i sædets omrâde anbragt anslagsflade.Furthermore, it is known (DE-PS 22 53 462) to separate the seat carrier from the shaft carrier with the purpose of setting the kv value, whereby a coupling device bearing ring over an external thread engages the built-in socket, loads the shaft carrier. axially and this presses the seat support against a stop surface located in the seat area.
I praksis anvendes et stort antal af meget forskellige ter-mostatventiler. Disse adskiller sig fx med hensyn til ind-bygningsstudsens længde (fordi tilslutningerne pà pladeradi-15 atorerne har forskellig afstand fra radiatorernes endeside) i termostatopsatsen (der findes ingen normerede koblingsind-retninger) og lignende. Dette har til folge, at der til hvert anvendelsesformàl anvendes en bestemt ventilindsats, og at der skal fremstilles og lagerfores en tilsvarende 20 mangfoldighed af konstruktioner.In practice, a large number of very different thermostat valves are used. These differ, for example, in respect of the length of the built-in plug (because the connections on the plate radiators have different distances from the end side of the radiators) in the thermostat set (no standard switchgear exists) and the like. This has the consequence that a specific valve insert is used for each use and that a corresponding variety of designs must be manufactured and stored.
Formâlet med opfindelsen er at angive et armatur af den i indledningen beskrevne art, hvis dele sâ vidt muligt kan anvendes ved de fleste udforelser, sâledes at der fâs store styktal og tilsvarende fremstillingsfordele.The object of the invention is to provide a luminaire of the type described in the preamble, the parts of which can be used as far as possible in most embodiments, so that large quantities and corresponding manufacturing advantages are obtained.
25 Denne opgave loses ifolge opfindelsen ved, at skillefugen mellem skaftbærer og sædebærer befinder sig i den indre del af ventilindsatsen, at den koblingsindretningen bærende ydre del er dannet af skaftbæreren, at skaftbæreren er fastgjort til indbygningsstudsen, at sædebæreren inden for indbyg-30 ningsstudsen har en holdeindretning, som sikrer dens aksiale indbygningsstilling, og at den cylindriske borings aksiale længde er betydelig længere end tætningshovedets aksiale længde.This task is solved according to the invention by the partition between the shaft carrier and the seat carrier being in the inner part of the valve insert, the outer part of the coupling device being formed by the shaft carrier, the shaft carrier being fixed to the flush-out nozzle, the seat carrier within the flush-mounted nozzle having a holding device which ensures its axial installation position and that the axial length of the cylindrical bore is considerably longer than the axial length of the seal head.

Ved denne konstruktion kan der anvendes en og den samme ven-tilindsats for indbygningsstudser med forskellig længde, da tætningshovedet ved en kortere længde blot griber dybere ind i den cylindriske boring. Den n0jagtige boringslængde retter 5 sig efter, hvilke længdevariationer af indbygningsstudsen der optræder i praksis. I hvert fald kan man med en eneste sædebærertype dække det samlede eller et væsentlig omrâde af disse længdevariationer.In this construction, one and the same venous insert can be used for different lengths of installation, since the sealing head, at a shorter length, simply engages deeper into the cylindrical bore. The exact bore length 5 depends on the length variations of the built-in spigot that occur in practice. In any case, a single seat carrier type can cover the entire or a substantial range of these length variations.
Da koblingsindretningen bæres af skaftbæreren, er der den 10 mulighed ved udskiftning eller ændring af skaftbæreren at foretage en tilpasning til forskellige termostatopsatser.Since the coupling device is carried by the shaft carrier, it is possible to change or change the shaft carrier to adapt to different thermostat sets.
Herved kan ogsâ et stort variationsomrâde af koblingsdiame-teren dækkes, fordi skaftbærerens udvendige diameter kan holdes mindre i koblingsomrâdet end ved udformning af kob-15 lingsindretningen pâ en skaftbæreren omgivende konstrukti-onsdel.Hereby, a large area of variation of the coupling diameter can also be covered, because the outside diameter of the shaft carrier can be kept smaller in the coupling area than in the design of the coupling device on a structural part surrounding the shaft carrier.
Nâr sædebæreren til fastlæggelse af kv-værdien er forsynet med en fast drossel, fâs en sérié af sædebærere hver med forskellig kv-Værdi, uden at antallet af sædebærere, som 20 holdes pâ lager, bliver for stort. For disse sædebærere er uafhængige af indbygningsstudsens længde og den onskede ter-mostatopsats.When the seat carrier for determining the kv value is provided with a fixed throttle, a series of seat carriers each with different kv value is obtained, without the number of seat carriers kept in stock becoming too large. For these seat carriers are independent of the length of the recess and the desired thermostat set.
I det enkleste tilfælde er skaftbæreren med et udvendigt ge-vind skruet ind i et indvendigt gevind af indbygningsstud-25 sen. Dette tillader anvendelsen af en forholdsvis lille diameter .In the simplest case, the shaft carrier with an external thread is screwed into an internal thread of the recess stud. This allows the use of a relatively small diameter.
Herved kan skaftbæreren uden for gevindert hâve et afsnit med st0rre diameter med en i en not holdt omkredstætning. üd over tætningsfunktionen kan der herved opnâs en aftrapning 30 til aksial bestemmelse af skaftbærerens position.This allows the shaft carrier outside the threaded section to have a larger diameter section with a circumferential seal in a groove. Thus, above the sealing function, a step 30 can be obtained for axially determining the position of the shaft carrier.
Det er særlig gunstigt, at skaftbæreren har en fastg0relses-It is particularly advantageous for the shaft carrier to have an attachment

4 indretning for i det mindste midlertidigt at holde sædebære-ren. Skaftbærer og sædebærer kan derfor sammenfojes allerede for indbygningen og derefter sammen indsættes i huset. Dette letter montagen.4 means for holding the seat carrier at least temporarily. The shaft carrier and seat carrier can therefore be joined together already for the installation and then put together in the house. This facilitates assembly.
5 Skaftbærerens fastgorelsesindretning kan være et indvendigt gevind, i hvilket et udvendigt gevind pâ sædebæreren er ind-skruet. Dette giver en varig fastgorelse, som ogsà kan ud-nyttes til at fiksere sædebæreren aksialt.The shaft carrier fastener may be an internal thread into which an external thread on the seat carrier is screwed. This provides a durable attachment that can also be utilized to fix the seat carrier axially.
Skaftbærerens fastgorelsesindretning kan imidlertid ogsà væ-10 re en omkredsnot, i hvilken pâ sædebæreren anbragte knast-fremspring fjedrende indrastes. For at opnâ denne fjederbe-vægelighed er materialeelasticiteten ofte tilstrækkelig. Den kan imidlertid ogsà opnâs ved hjælp af yderligere aksial-slidser.However, the attachment device of the shaft carrier may also be a circumferential groove in which the cam protrusion is resiliently mounted on the seat carrier. To achieve this spring flexibility, the material elasticity is often sufficient. However, it can also be obtained by means of additional axial slots.
15 Det er gunstigt, at skaftbærerens fastgorelsesindretning er anbragt pâ den indvendige side af en ringforlængelse, som udvendig-t bærer det udvendige gevind til fastgorelse pâ ind-bygningsstudsen. Dette giver en aksial kort konstruktion.It is advantageous that the shaft carrier fastener is disposed on the inner side of an annular extension which carries the outer thread for fastening to the mounting spigot. This gives an axial short construction.
Sædebærerens holdeindretning kan især være dannet af en om-20 kredsflange, som samvirker med en endeflade af skaftbæreren.In particular, the seat carrier retaining device may be formed by a circumferential flange which cooperates with an end face of the shaft carrier.
Fx kan omkredsflangen definere endestillingen ved en skrue-fastgorelse af sædebæreren pâ skaftbæreren.For example, the circumferential flange may define the end position by a screw attachment of the seat support to the shaft support.
Ved en anden udforelsesform kan omkredsflangen fra skaftbærerens endeflade trykkes mod en aftrapning i indbygnings-25 studsen. Herved holdes sædebæreren aksialt sikkert.In another embodiment, the circumferential flange from the end surface of the shaft carrier may be pressed against a step in the recess bore. This keeps the seat carrier axially secure.
Sædebæreren kan, som sædvanlig, bestâ af métal. Ved en gan-ske særlig foretrukken udforelsesform bestâr sædebæreren derimod af kunststof. Sâdanne kunststofdele kan ved sprojt-ning fremstilles meget billige og alligevel præcise. Man be-30 hover ikke at frygte overbelastninger af kunststoffet iThe seat carrier can, as usual, consist of metal. In a particularly preferred embodiment, on the other hand, the seat support is made of plastic. Such plastic parts can, by spraying, be manufactured very cheaply and yet accurately. There is no need to worry about plastic overloads

5 drift, da kun de af lukkestykket pâ saedet udovede kræfter skal overf0res som trækkræfter.5 operation, since only the forces exerted by the closure on the seat must be transferred as pulling forces.
Især kan kunststoffet være koldflydende, og pâ omkredsflan-gens endeflader kan ringvulster rage frem. Dette giver en 5 sikker fastklemning af omkredsflangen ved indskruning af skaftbæreren.In particular, the plastics may be cold-flowing, and annular bumps may protrude on the end faces of the circumferential flange. This provides a secure clamping of the circumferential flange by screwing in the shaft carrier.
Den cylindriske borings aksiale længde retter sig efter ind-bygningsstudsens længdevariationer. I praksis udg0r længden mindst 1,8 gange, fortrinsvis imidlertid mere end 2 gange 10 tætningshovedets aksiale længde. Især har den cylindriske boring en længde, som omtrent svarer til kammerets h0jde i huset. Porskydningsvejen bor være mindst lig med den halve h0jde af kammeret i huset. Den bedste pladsudnyttelse fâs, nâr den cylindriske boring har en længde, som omtrent er lig 15 med rorforlængelsens længde.The axial length of the cylindrical bore conforms to the length variations of the recess. In practice, the length is at least 1.8 times, preferably more than 2 times the axial length of the seal head. In particular, the cylindrical bore has a length approximately equal to the height of the chamber in the housing. The porch shooting path should be at least equal to half the height of the chamber in the housing. The best space utilization is obtained when the cylindrical bore has a length approximately equal to the length of the rudder extension.
Ved en foretrukken udforelsesform har skaftbærerens ydre del en fastgorelsesindretning til anbringelse af en koblingsind-retningen bærende adapterring. Man beh0ver derfor til til-pasning til en anden termostatopsats kun at pâsætte eller 20 udskifte adapterringen. I 0vrigt kan skaftbæreren anvendes uforandret. Dette giver betydelige rationaliseringsfordele.In a preferred embodiment, the outer portion of the shaft carrier has a fastener for attaching a coupling device bearing adapter ring. It is therefore necessary to fit or replace the adapter ring only to fit another thermostat set. Otherwise, the shaft carrier can be used unchanged. This provides significant rationalization benefits.
Det kan anbefales, at adapterring-fastgorelsesindretningen har et udvendigt gevind, som samvirker med et ringformet an-slag. Ved fastskruning af denne adapterring mod anslaget fâs 25 en defineret stilling.It is recommended that the adapter ring fastener has an external thread which cooperates with an annular impact. By screwing this adapter ring against the stop 25 a defined position is obtained.
Adapterrîng-fastg0relsesîndretningen kan være anbragt aksi-alt uden for en permanent pâ skaftbæreren anbragt koblings-indretning. Adapterringen er derfor kun n0dvendig i en del af anvendelsestilfældene.The adapter ring attachment device may be positioned axially outside a permanent coupling device mounted on the shaft carrier. The adapter ring is therefore only necessary in some of the applications.
30 Ved en foretrukken udforelsesform er der serget for, at enIn a preferred embodiment, it is ensured that one

6 permanent pâ skaftbæreren anbragt koblingsindretning dannes af en koblingsring, som er drejeligt, men aksialt kun med et ringe spil holdt pâ en cylindrisk lejeflade af skaftbæreren og er forsynet med en radialnæse til indgreb i en radialnot 5 pâ indbygningsstudsens endeflade. Den drejelige koblingsring kan hâve en ringéré radial tykkelse end en ring, som kan pâ-skrues. Radialnæsen giver da den nodvendige drejesikring.6 permanently affixed to the shaft support is formed by a coupling ring which is rotatable, but axially with only a small spindle held on a cylindrical bearing surface of the shaft support and is provided with a radial nose for engaging a radial groove 5 on the end surface of the recess. The swivel coupling ring can have a radially lower radial thickness than a ring which can be screwed on. The radial nose then provides the necessary turning protection.
Det er herved gunstigt, at den cylindriske lejeflade har en flad omkredsnot, og koblingsringen er deformeret punktvis 10 ind i omkredsnoten. En sâdan punktvis déformering til formâl for aksialsikringen kan lettest anbringes i tyndere ringom-râder, som optræder pâ bunden af aksialnoter.It is hereby advantageous that the cylindrical bearing surface has a flat circumferential groove and the coupling ring is deformed pointwise 10 into the circumferential groove. Such point-wise deformation for the purpose of the axial protection can most easily be applied in thinner ring areas which appear at the base of axial grooves.
Formâlstjenligt har den cylindriske lejeflade en st0rre dia-meter end adapterring-fastgorelsesindretningens udvendige 15 gevind, og koblingsringen danner med sin endeflade det ring-formede anslag. Dette gor en enkel fremstilling af skaftbæreren mulig, uden at det ringformede anslag skal udformes pâ den.Preferably, the cylindrical bearing surface has a larger diameter than the external thread of the adapter ring fastener, and the coupling ring, with its end surface, forms the annular stop. This allows for simple manufacture of the shaft support without the annular stop having to be formed on it.
Endvidere kan der mellem adapterring-fastgorelsesindretnin-20 gen og den permanent pâ skaftbæreren anbragte koblingsindretning være anbragt en omkredsnot med konisk sidevæg til aksial arretering af termostatopsatsen.Further, between the adapter ring fastener and the coupling device permanently mounted on the shaft carrier, a circumferential groove with conical side wall may be provided for axial arrangement of the thermostat set.
Med særlig fordel er indbygningsstudsen og den den cylindriske boring bærende hus-end'edel svejset ind i en kammeret be-25 grænsende hus-midterdel. Indbygningsstuds og hus-endedel fremstilles derfor adskilt fra hinanden. Dette er tillade-ligt, uden at en efterbearbejdning efter sammensvejsningen er nodvendig, fordi tætningshovedet i den cylindriske boring i hoj grad udligner tolerancer. Desuden beh0ver man kun at 30 anvende en indbygningsstuds af en anden længde, uden at de ovrige ventilbestanddele skal ændres for at foretage en til-pasning til en bestemt radiator.With particular advantage, the housing end and the cylindrical bore bearing end of the housing are welded into a chamber bounding housing center part. The housing and housing end part are therefore manufactured separately from one another. This is permissible without the need for post-welding after machining, because the sealing head in the cylindrical bore greatly offsets tolerances. In addition, it is only necessary to use a built-in plug of a different length, without the other valve components having to be changed in order to adapt to a particular radiator.

Længere ude findes et afsnit 26 med storre diameter med en i en not holdt omkredstætning 27. Ved anlæg mod en aftrapning 28 af indbygningsstudsen 4 er skaftbærerens 12 aksialstilling sik-ret ved hjælp af dette afsnit 26.8 axially on the valve shaft 15. The shaft carrier 12 has a cylindrical extension 21 which is provided with an external thread 22 for engagement with an internal thread 23 of the mounting spigot 4 and with an internal thread 24 for interaction with the an external thread 25 of the seat carrier 13. Further out there is a larger diameter section 26 with a circumferential seal 27 held in a groove. By abutment against a step-down 28 of the recess 4, the axial position of the shaft carrier 12 is secured by this section 26.
10 Sædebæreren 13, som bestâr af métal, fx messing, har en om-kredsflange 29, som virker sammen med en endeflade 30 af skaftbæreren 12 og pâ denne mâde sikrer sædebærerens 13 aksialstilling. Pâ den anden side af sædet 31 strækker der sig en rorforlængelse 32 i en cylindrisk boring 33 i hus-endede-15 len 3. Rorforlængelsen er forsynet med et tætningshoved 34, som har en omkredstætning 35.The seat carrier 13, which consists of metal, for example brass, has a circumferential flange 29 which cooperates with an end surface 30 of the shaft carrier 12 and in this way ensures the axial position of the seat carrier 13. On the other side of the seat 31, a rudder extension 32 extends into a cylindrical bore 33 in the housing end 15 3. The rudder extension is provided with a sealing head 34 having a circumferential seal 35.
Som koblingsindretning 36 til fastgorelse af en termostatop-sats er der anbragt en koblingsring 37, som pâ den udvendige omkreds har aksialnoter 38, og som pâ en cylindrisk lejefla-20 de 39 af skaftbæreren 12, sâ længe denne endnu ikke er ind-bygget, er holdt drejelig. Til forhindring af at den falder af, er koblingsringens 37 materiale pâ flere af de med en pii forsynede steder 40 deformeret ind i en flad omkredsnot 41 ved korning eller lignende. Koblingsringen er derfor med 25 ringe aksialt spil sikret mod at falde af. Koblingsringen har endvidere en radialnæse 42, som griber ind i en radial-not 43 pâ indbygningsstudsens 4 endeside. Pâ denne mâde kan skaftbæreren 12 skrues ind i huset? alligevel er koblingsringens 37 drejevinkelstilling sikret. En omkredsnot 44 med 30 skrâ sidevæg 45 er anbragt foran denne koblingsring. Nâr en termostatopsats er blevet skubbet op pâ koblingsindretningen 36, kan et radial indstilleligt organ af termostatopsatsen gribe ind i omkredsnoten 44 og sikre aksialstillingen.A coupling ring 37 is provided as coupling device 36 for fixing a thermostat set, which has on the outer circumference axial grooves 38 and which on a cylindrical bearing surface 39 of the shaft carrier 12, as long as it is not yet incorporated. is kept rotatable. In order to prevent it from falling off, the material of the coupling ring 37 is deformed into a flat circumferential groove 41 at several of the locations provided with a ply 40 by grinding or the like. The clutch ring is therefore secured with 25 low axial clearance against falling. The coupling ring further has a radial nose 42 which engages a radial groove 43 on the end side of the mounting spout 4. In this way can the shaft carrier 12 be screwed into the housing? nevertheless, the pivot angle position of the coupling ring 37 is secured. A circumferential groove 44 with 30 inclined side walls 45 is arranged in front of this coupling ring. Once a thermostat set has been pushed up on the coupling device 36, a radially adjustable member of the thermostat set may engage the circumferential groove 44 and secure the axial position.

Foran denne omkredsnot 44 er der et udvendigt gevind 46, som har en noget ringere diameter end lejefladen 39. En adapter-ring kan pâskrues dette gevind, som det senere bliver for-klaret i forbindelse med fig. 4 og 5.In front of this circumferential groove 44 is an external thread 46 having a somewhat smaller diameter than the bearing surface 39. An adapter ring can be screwed onto this thread, as will be explained later in connection with FIG. 4 and 5.
5 Udforelseseksemplet i fig. 2 bestâr i stor udstrækning af de samme dele som det i fig. 1 viste. Der anvendes derfor for tilsvarende dele med 100 forhojede henvisningsbetegnelser. Forskelligt er i det væsentlige folgende: Indbygningsstudsen 104 har en storre længde end i fig. 1. Som folge deraf be-10 finder tætningshovedet 134 sig ikke mere pâ den nedre, men pâ den 0vre ende af den cylindriske boring 133 i hus-endede-len 103. Den mulige forskydningsvej er omtrent lig med den halve hojde af kammeret 10. Alt i ait kan den cylindriske boring 133 omtrent svare til h0jden af kammeret 10.5 The embodiment of FIG. 2 consists largely of the same parts as that of FIG. 1. Therefore, corresponding parts with 100 elevated reference numerals are used. Differences are essentially as follows: The recess nozzle 104 has a greater length than in FIG. 1. As a result, the sealing head 134 is no longer located on the lower, but on the upper end of the cylindrical bore 133 in the housing end portion 103. The possible displacement path is approximately equal to half the height of the chamber 10. All in all, the cylindrical bore 133 may approximately correspond to the height of the chamber 10.
15 Sædebæreren 113 og dermed ogsâ sædet 131 bestâr af kunst- stof. Den er pâ sin ydre ende forsynet med aksialslidser 47, sâledes at de derimellem værende afsnit 48 kan b0jes fje-drende indad. De bærer knastfremspring 124, som kan indraste i en tilsvarende omkredsnot 125 af skaftbæreren 112. Dette 20 giver en i det mindste midlertidig fastgorelse af sædebæreren pâ skaftbæreren, som det er hensigtsmæssigt for indbyg-ningen. Omkredsflangen 129 har en omlobende ringvulst 49, sâledes at denne ringvulst 49 trykkes mod en aftrapning 50 af huset 101 ved fastskruning af skaftbæreren 112 i indbyg-25 ningsstudsen 104, hvorved kunststoffet delvist deformeres ved koldflydning.15 The seat carrier 113 and thus the seat 131 also consist of synthetic material. It is provided at its outer end with axial slots 47, so that the intermediate sections 48 can be resiliently bent inwardly. They carry cam protrusions 124 which can project into a corresponding circumferential groove 125 of the shaft carrier 112. This 20 provides at least temporary attachment of the seat carrier to the shaft carrier as is convenient for the incorporation. The circumferential flange 129 has a circumferential annular bead 49 such that this annular bead 49 is pressed against a step 50 of the housing 101 by screwing the shaft carrier 112 into the recess nozzle 104, thereby partially deforming the plastic by cold flow.
Ved udf0relsesformen if0lge fig. 3 er vist en sædebærer 213 med sæde 231 og lukkestykke 214, som kun adskiller sig fra de tilsvarende i fig. 1 og 2 ved, at der koncentrisk til sæ-30 det er anbragt en drosselboring 51, med hvilken ventilens kv-værdi kan fastlægges. Ved udskiftning af sædebæreren kan den maksimale gennemstromningsmængde derfor vælges svarende til varmeanlæggets data.In the embodiment according to FIG. 3, a seat carrier 213 with seat 231 and closure 214 is shown which differs only from those of FIG. 1 and 2 in that a throttle bore 51 is arranged concentrically to the seat with which the kv value of the valve can be determined. Therefore, when replacing the seat carrier, the maximum flow rate can be selected according to the heating system data.

Ved udforelsesformen ifolge fig. 4 og 5 er skaftbæreren 12 i fig. 1 kun suppleret med en pâ det udvendige gevind 46 skru-et adapterring 52. Denne er pâskruet, til den stoder mod an-slagsfladen 53, som er dannet af koblingsringens 37 endefla-5 de. Adapterringen 52 har pâ omkredsen talrige aksialnoter 54, som er tilpasset en anden termostatopsats end koblingsringens 37 aksialnoter. Adapterringen kan naturligvis ogsâ hâve en anden form, fx udvendigt være forsynet med et gevind eller hâve en væsentlig storre diameter.In the embodiment according to FIG. 4 and 5, the shaft carrier 12 in FIG. 1 is only supplemented with an adapter ring 52 screwed to the external thread 46. This is screwed until it abuts the abutment surface 53 formed by the end face of the coupling ring 37. The adapter ring 52 has on its circumference numerous axial grooves 54 which are adapted to a different thermostat arrangement than the axial grooves of the coupling ring 37. Of course, the adapter ring may also have a different shape, for example, be externally provided with a thread or have a substantially larger diameter.
10 Koblingsindretningen 36 kan fx bruges i forbindelse med en termostatopsats, som er kendt fra DE-PS 32 36 371. Koblingsindretningen med adapterringen 52 kan beny~ es i forbindelse med en termostatopsats ifolge DE-PS 31 12 138.The coupling device 36 can, for example, be used in connection with a thermostat set known from DE-PS 32 36 371. The coupling device with the adapter ring 52 can be used in connection with a thermostat set according to DE-PS 31 12 138.
Ved hjælp af det beskrevne armatur kan der hos producenten 15 vælges et til den valgte radiator passende ventilhus 101.By means of the luminaire described, a valve housing 101 suitable for the selected radiator can be selected from the manufacturer 15.
Uafhængigt deraf kan den monter, der skal installere radia-toren, med i stor udstrækning de samme komponenter efter kundens onske vælge et bestemt fabrikat af termostatopsatsen og efter anlæggets data en bestemt kv-værdi. Trods ait er 20 hândteringen meget enkel, da skaftbærer og sædebærer kan indbygges eller tages ud sammen.Independently of this, the stand which is to install the radiator can to a large extent the same components, according to the customer's wishes, select a specific make of the thermostat set and according to the data of the plant a specific kv value. Despite this, the 20 handling is very simple, as the shaft carrier and seat carrier can be built-in or removed together.
Rorforlængelsen 32 kan ogsâ gennemgâende eller i stor udstrækning hâve den samme udvendige diameter. I dette tilfæl-de betragtes som "tætningshoved" kun tætningsomrâdet omkring 25 omkredstætningen 35, som maksimalt svarer til det tredobbel-te af omkredsnotens bredde.The rudder extension 32 may also, or to a large extent, have the same outside diameter. In this case, the "sealing head" is considered only the sealing area about the circumferential seal 35, which corresponds to a maximum of three times the width of the circumferential groove.
Armaturet er ikke indskrænket til svejsede huse, men kan ogsâ anvendes ved stobte huse. Det har ganske vist særlige fordele ved pladeradiatorer, men kan ogsâ indsættes ved an-30 dre radiatorer og til andre formâl.The luminaire is not confined to welded houses, but can also be used for molded houses. While it has special advantages for plate radiators, it can also be used with other radiators and for other purposes.
