Thermostatic valve

The invention relates to a thermostatic valve, in particular for a radiator with a valve housing and a removable, the thermostat od. The like. Receiving upper part. Thermostatic valves of this type are already known. You can Remove the upper part with the thermostat or the like and replace it with a handwheel or a similar component with which the Valve can be operated by hand.

Conversely, the valve can initially be used as a operate manually operated valve and first to one later switch to automatic, i.e. thermostat operation, especially the last one Operating mode should the position of the valve housing? in the Retain the wiring harness so that the changeover can be carried out without problems.

The valve housing is installed in the supply line to a radiator. His lens opposite the radiator, one! '/ and, a window ledge and d-τΐ. is therefore certain. That means that when switching from manual to Thermostat operation with regard to the arrangement of the thermostat has only one possibility. Consequently it can happen thatP. this conversion is opposed by spatial difficulties.

The object of the invention is therefore to to create a thermostatic valve of the type mentioned, with which at least two different There are mounting options for the upper part. A thermostatic valve is used to solve this problem

vorsreschla.ren according to the umbrella term of claim 1, and it is according to the invention according to the characterizing Part of the first claim formed. Pas middle piece allows for example due to its shape a horizontal arrangement of the longitudinal axis of the upper part, despite the vertical course of the valve spindle. If an angular assignment of the longitudinal axes of Valve spindle and upper part is not desired, the intermediate piece can be left v / c and the upper part if necessary. with the interposition of an intermediate ring or dpi. place directly on the lower part. Manufacturing this thernostat valve has advantages in that both a "straight" and an "angled" version from the same upper part and the same lower part exist and they can only be achieved by inserting an intermediate piece, in particular the curved or angular spacer, differentiate.

In a particularly preferred embodiment of the invention the connection devices on the valve housing and on the end of the intermediate piece remote from the housing are the same or

271U12

at least similar, so that the direct or indirect connection of the upper part is possible without special measures. Under "similar" is used in this Case understood a training which, despite any possible existing, minor differences, the problem-free attachment of the upper part both on the intermediate piece and on Housing makes possible without manipulation or expensive additional parts.

According to a further embodiment of the invention it is proposed that the valve housing with the intermediate piece and the latter are connected to the upper part via an upper screw joint. This type of attachment is easy and hassle-free. Simple tools that usually anyone can use are sufficient for fastening and loosening are available so that even a layperson can carry out the conversion if necessary «

Another variant of the invention is characterized in that the intermediate piece on his, the upper part facing end a longitudinally displaceable transmission member arranged in extension of the longitudinal axis of the thermostat

and a Piewegimgs-Umlenkelied that can be actuated by this possesses, by means of which the movements of the thermostatic working element on the valve spindle and lui ^ ekehrt are transferable. Since dead ends with a control valve normally cannot be accepted, is for the valve spindle or a valve spindle extension, the unlenklink, the transmission link and the themostatic working element or one of this actuated! '. share at least one force fit, in ilin- and dressing-up: effective connection available.

The Obertra ^ unpsjrlied preferably consists of one Bolt, which od in particular by a collar. Dfrl. against Pulling out of the housing of the intermediate piece is secured. An impermissibly deep indentation in the opposite direction is prevented by the deflector.

Characterizes another embodiment of the invention characterized in that the deflecting member consists of a double lever rotatably mounted in the housing of the intermediate piece,

its one lever arm on Obertrar: unrsplie.l and its Another lever arm is in contact with the valve spindle or a spindle extension or it is 5Te!; unr> elt. In the latter case, of course, the connection must be like this be designed so that all parts move as necessary can perform and dead stretches are avoided. In the case of a thermostatic valve with only adjacent Lever hooks, which are preferred per se, are shown in Further development of the invention proposed that the adjacent parts of the Uebelaroenden nockenarti <T formed are. During their pivoting movement, they can be at the assigned end faces of the valve spindle or a Roll off the valve spindle extension on the one hand and the transmission member on the other hand and / or slide along it.

In the drawing is an embodiment of the invention shown on the basis of a side view partially cut in the vertical direction.

The embodiment is a thermostat-controlled radiator valve with a valve housing 1, in with which the valve seat is located, with which one

closureor attached to the inner end of the valve spindle 2 cooperates. never connections 3 and 4 for the incoming and the continuing line are in place in the example shown at right angles to each other. In the ^ e showed mounting tape zips the valve stem end as a result up.

On the upper end 5 of the housing 1 is a drill or angular intermediate piece 6 placed and means an upper throw nut 7 held. The latter and the intermediate piece can advertise made of plastic. The fastening outer thread of the valve housing 1 is with R denotes.

At the end 9 of the intermediate piece 6 remote from the housing, the removable upper part K) having the thermostat is screwed onto the thread 20 by means of a further union nut 11. The upper nut 11 is rotatable but kept Jjnverschiebbar ara shell while you is "top union nut gate 7 in the same '.'eise to Ztvischenstück C- anTcbrac'it. Since the upper throw nuts 7 and 11 are designed and oriented in the same way, the upper part 10 can be attached directly to the upper part 10, omitting the intermediate piece 6

Tighten valve housing 1. The intermediate piece f> and the upper part IO can be fixed in any i'rohla ^ c.

The thernostat working element, for example the piston of an expansion unit, transmits its working movement to an IJberrafungsglicd 13, which consists in particular of a longitudinally displaceable bolt mounted in a molded sleeve 14. The latter carries at its inner end an Au ^p enbund 10, the / ep withdrawal and an inadmissible Verschiebebev: un x prevented against arrow 12th

The working movement directed in the direction of arrow 12 of the transmission member 13 is via the Bewegungsunps deflecting member 15 passed on to the valve spindle 2. The movement uril link 15 consists of a double-armed one Lever with, in particular, lever arms of the same length, which can be rotated about axis 16 in the housing of the intermediate piece 6 is stored. In this case, the transmission element 13 on the one hand and the valve spindle 2 on the other hand parts 17 and 18 of the lever arm ends of the deflecting member 15 which are in contact with the valve spindle 2 designed like a cam.
