Ein Schutzgehäuse 1 weist einen Kasten 2 mit einer Rück-30 wand 3 und vier Seitenwänden 4,5,6 und 7 auf. Dieser Kasten wird mit Hilfe von Mauerankern 48' in der Wand befestigt. In der Seitenwand 4 befindet sich eine Durchtrittsöffnung 8, an welche ein Leerrohr 9 anschliesst, für den Durchtritt eines Kapillarrohres 10. Gleichartige Öffnungen können 35 auch in den Seitenwänden 5 und 7 vorgesehen sein. In der Seitenwand 6 befinden sich drei Öffnungen 11,12 und 13 für den Durchtritt von drei Anschlussrohren 14,15 und 16 einer Fussbodenheizung. Beispielsweise dient das Rohr 15 als gemeinsamer Zulauf, während die Rohre 14 und 16 je einer 40 Schleife der Fussbodenheizung zugeordnet sind. A protective housing 1 has a box 2 with a rear wall 3 and four side walls 4, 5, 6 and 7. This box is fixed in the wall with the help of wall anchors 48 '. In the side wall 4 there is a passage opening 8, to which an empty tube 9 connects, for the passage of a capillary tube 10. Similar openings 35 can also be provided in the side walls 5 and 7. In the side wall 6 there are three openings 11, 12 and 13 for the passage of three connecting pipes 14, 15 and 16 of an underfloor heating. For example, the pipe 15 serves as a common inlet, while the pipes 14 and 16 are each assigned to a loop of the underfloor heating.

Ein Verbindungsstück 17 weist drei parallele Stutzen 18, 19 und 20 auf, deren Achsen in einer parallel zur Rückwand 3 ■ verlaufenden Ebene liegen. Am oberen Ende ist ein Stutzen 21 vorgesehen, dessen Achse senkrecht dazu steht und in den ein 45 Entlüftungsventil 22 eingesetzt ist. Einstückig mit dem Verbindungsstück und im Abstand davon ist ein zweiteiliger Flansch 23 ausgebildet, der mit Hilfe von Muttern 24 auf Gewindebolzen 25 festgeschraubt ist, die durch Befestigungslöcher des Flansches greifen und mit ihrem Schaftende an der 50 Rückwand 3 festgeschweisst sind. Auf diese Weise wird das Verbindungsstück 17 im Abstand von der Rückwand 3 gehalten. A connecting piece 17 has three parallel connecting pieces 18, 19 and 20, the axes of which lie in a plane running parallel to the rear wall 3. At the upper end a nozzle 21 is provided, the axis of which is perpendicular thereto and into which a vent valve 22 is inserted. In one piece with the connecting piece and at a distance therefrom, a two-part flange 23 is formed, which is screwed onto threaded bolts 25 with the aid of nuts 24, which grip through fastening holes in the flange and are welded to the rear wall 3 with their shaft end. In this way, the connector 17 is held at a distance from the rear wall 3.

Der Stutzen Ï8 kann mit einer Universalkupplung 26 mit dem Anschlussrohr 14, der Stutzen 20 mittels einer Universal-55 kupplung 27 mit dem Anschlussrohr 16 verbunden werden. Das Gehäuse 28 eines Thermostatventils 29 ist einerseits über eine eingeschraubte Universalkupplung 30 mit dem Anschlussrohr 15 verbindbar und andererseits mittels einer Überwurfmutter 31 mit einem Nippel 32 zu verbinden, der in 60 den Stutzen 19 fest eingelötet ist. Am Gehäuse ist mittels eines Spannringes 33 ein Aufsatz 34 befestigt, der ein Arbeitselement 35 enthält. Dieses ist über das Kapillarrohr 10 mit einem aussen liegenden Fühler und Einstellelement verbunden. Fig. 2 lässt erkennen, dass der Abstand zwischen der Mittel-65 achse des Ventilgehäuses 28 von der Öffnung des Kastens 2 gerade um soviel grösser als der Durchmesser des Aufsatzes 34 ist, dass dieser Aufsatz schräggestellt trotz des Vorhandenseins des Anschlussrohres 16 in das Schutzgehäuse einpasst. The connector Ï8 can be connected to the connecting pipe 14 with a universal coupling 26, the connector 20 with a universal coupling 27 to the connecting pipe 16. The housing 28 of a thermostatic valve 29 can be connected on the one hand to the connecting pipe 15 via a screwed-in universal coupling 30 and, on the other hand, can be connected by means of a union nut 31 to a nipple 32, which is firmly soldered into the socket 19 in 60. An attachment 34, which contains a working element 35, is fastened to the housing by means of a clamping ring 33. This is connected via the capillary tube 10 to an outside sensor and setting element. Fig. 2 shows that the distance between the center 65 axis of the valve housing 28 from the opening of the box 2 is just so much larger than the diameter of the attachment 34 that this attachment fits obliquely in the protective housing despite the presence of the connecting tube 16 .

Aus den Fig. 3 und 4 ersieht man, dass zum Schutzgehäuse 1 ausser dem Kasten 2 noch ein Schieberahmen 36 mit Flansch 37 und ein Deckel 38 bzw. 39 gehört. Der Schieberahmen weist Schlitze 40 auf, die von Schrauben durchsetzt werden, welche in das Gewinde von Blind-Einnietmuttern 41 in den Seitenwänden 5 und 7 greifen. Mit Hilfe des Schieberahmens wird ein genaues Fluchten bezüglich der Wand- oder Bodenoberfläche erzielt. Der Deckel 38 ist bei der Ausführungsform der Fig. 3 als Einstecktür mit einem Drehver-schluss 42 ausgeführt. In Fig. 4 ist der Deckel 39 lediglich als abnehmbare Platte ausgebildet, die an einem am Schieberahmen 36 befestigten Profil 44 aufliegt, dort mit Federlaschen 43 gesichert ist und mit einem Fussbodenbelag 45 belegt werden kann, also begehbar ist. 3 and 4 it can be seen that in addition to the box 2, the protective housing 1 also includes a sliding frame 36 with a flange 37 and a cover 38 and 39, respectively. The sliding frame has slots 40 which are penetrated by screws which engage in the thread of blind rivet nuts 41 in the side walls 5 and 7. With the help of the sliding frame, an exact alignment with the wall or floor surface is achieved. In the embodiment of FIG. 3, the cover 38 is designed as an insertion door with a rotary lock 42. In Fig. 4, the lid 39 is only designed as a removable plate which rests on a profile 44 fastened to the sliding frame 36, is secured there with spring clips 43 and can be covered with a floor covering 45, that is to say it can be walked on.

Bei der Ausführungsform nach Fig. 3 werden dieselben Bauteile wie bei dem Ausführungsbeispiel nach den Fig. 1 und 2 verwendet mit Ausnahme des Aufsatzes und der ihn umgebenden Teile (Fig. 3). Der hier verwendete Aufsatz 46 In the embodiment according to FIG. 3, the same components as in the embodiment according to FIGS. 1 and 2 are used with the exception of the attachment and the parts surrounding it (FIG. 3). The attachment 46 used here

weist ausser dem Arbeitselement und dem Temperaturfühler einen Drehgriff 47 als Einstellelement auf. Der Temperaturfühler befindet sich hinter den Luftschlitzen 48. Der Aufsatz 46 ragt durch eine Durchtrittsöffnung 49 nach aussen. Die s Lage dieser Durchtrittsöffnung und der Abstand des Deckels 38 von der Mittelachse des Ventilgehäuses sind so gewählt, dass ein wesentlicher Teil des Drehgriffs 47, insbesondere auch die Luftschlitze 48, vor dem Deckel 38 liegen. Eine Balgmembran 50 schliesst einerseits an den Rand der Durchtritts-io Öffnung 49 und andererseits an das Ventil 29 unterhalb des Drehgriffs 47 an, so dass eine Luftzirkulation von innen nach aussen und umgekehrt verhindert wird. has, in addition to the working element and the temperature sensor, a rotary handle 47 as an adjusting element. The temperature sensor is located behind the air slots 48. The attachment 46 protrudes outwards through a passage opening 49. The position of this passage opening and the distance of the cover 38 from the central axis of the valve housing are selected such that a substantial part of the rotary handle 47, in particular also the air slots 48, lie in front of the cover 38. A bellows membrane 50 connects on the one hand to the edge of the passage opening 49 and on the other hand to the valve 29 below the rotary handle 47, so that air circulation from the inside to the outside and vice versa is prevented.

Bei der Ausführungsform nach Fig. 1 und 2 wird ein Dek-kel 38, jedoch ohne Durchtrittsöffnung 49, verwendet. 15 Die Abmessungen des Schutzgehäuses sind so getroffen, dass nach einem Verdrehen des Ventilgehäuses um 90° der Drehgriff 47 vollständig in das Gehäuse passt, sofern ein Anschlussrohr 16 bzw. 14 entfallt. In the embodiment according to FIGS. 1 and 2, a cover 38 is used, but without a passage opening 49. 15 The dimensions of the protective housing are such that after turning the valve housing by 90 °, the rotary handle 47 fits completely into the housing, provided that a connecting pipe 16 or 14 is omitted.

tenwand (4,5,7) of the protective housing (1) is provided. The second nozzle of the

Connection piece parallel to the axis of the valve housing. This arrangement is particularly suitable for two connecting pipes running in parallel, onto which the connecting piece of the connecting piece and the valve housing can be attached. In addition, the protective housing has relatively small dimensions.

In a preferred embodiment, the connecting piece has three parallel connecting pieces, the middle of which is connected to the valve housing. In this way, two separate heating circuits of the underfloor heating can be influenced with one valve. If only one heating circuit is to be connected, the other nozzle can be closed.

In addition, the connecting piece can have on its upper side a further connection piece pointing towards the cover for inserting a ventilation valve. This vent valve is effective for both wall mounting and floor mounting. Of course, another element, e.g. a pressure gauge, thermometer.

It is also expedient if the connecting piece carries a flange with fastening holes on its side facing away from the cover and the protective housing on its rear side carries threaded elements for fastening the flange. This results in a very simple construction. In particular, the threaded elements can be formed by threaded bolts welded to the rear wall.

It makes assembly easier if a nipple connected to the valve housing via a union nut is soldered to the associated connecting piece of the connecting piece.

When using an attachment with a rotary handle as an adjusting element, it is advisable to provide the passage opening in the lid and to adapt it to the diameter of the rotary handle, and to choose the position of the passage opening and the depth of the protective housing so that the rotary handle leaves the lid over a substantial part of its axial length protrudes. Although the valve is still covered, the setpoint can be easily adjusted using the rotary handle. The temperature sensor can also be located in the protruding part of the attachment.

In the latter case, it is favorable if an elastic sealing sleeve rests on the one hand on the edge of the passage opening and on the other hand on the valve, in particular on the neck of the attachment, below the rotary handle. On the one hand, this sealing sleeve prevents dirt from penetrating into the protective housing and, on the other hand, prevents the temperature sensor from being influenced by the air heated inside the protective housing.

When using an attachment which is connected to the temperature sensor and / or the adjusting element via a capillary tube, the passage opening for the capillary tube should be provided in at least one side wall, preferably in three side walls of the protective housing. This capillary tube can then also be covered up to the temperature sensor or to the setting element.

So that this capillary tube does not have to be installed during construction, an empty tube for receiving the capillary tube can be connected to the passage opening.

In a preferred embodiment, the depth of the protective housing is greater than the diameter of an attachment with a rotary handle and the distance of at least one side wall from the axis of the installed valve housing is greater than the distance of the end face of the rotary handle from this axis. This means that the valve housing with attachment can also be pivoted completely into the interior of the protective housing if so desired. This request can occur, for example, if an adjustment is made only rarely or is to be completely prevented by unauthorized persons (authority model). If the valve serves as a return temperature limiter, no further precautions need to be taken; if it is used for room temperature control, a remote temperature sensor or 5 remote adjustment elements must be connected via a capillary tube.

Furthermore, it is advantageous if the distance of the central axis of the valve housing from the cover is greater than the diameter of an attachment which has only the working element. In this case, this working element of smaller diameter can still be completely accommodated in the housing if there is still a connecting pipe in the pivoting direction.

In order to obtain a good adaptation to the local conditions, the protective housing for fastening the cover can have a sliding frame which is known per se.
