Description

HEATING DISTRIBUTOR

The present innovation relates to a heating circuit distributor for Collective heating operated with liquid medium. Such heating circuit distributors are used for the adjustable or controllable division of the circulating heating medium to local individual heating points. This is required for underfloor heating, for example. Underfloor heating consists of individual heating circuits, which are provided by the collective heating via a A multitude of setting and regulating organs are averse. This setting and control organs require a lot of space and must be accommodated in an accessible manner.

To save space, it is already known to use a pipe socket, which is connected to the flow or return via a shut-off device. In this pipe socket, the pipe jacket is offset by 180 ° openings made in pairs at opposite points »In one Opening, an actuator is used which acts directly on a valve inserted into the other opening.

These known arrangements have the disadvantage that the internals a considerable flow resistance arises in the pipe. In contrast, the task of the innovation is a heating circuit distributor of the type mentioned to make available, in which the heating medium is not dammed up inside the distributor pipe by internals.

The solution is that the connection between the actuator and the valve and branching member arranged in the opposite pipe wall is essentially restricted to a thin solid shaft. This is advantageously stored above and below. The storage as well all other fixtures screwed into the pipe wall are relocated as far as possible in an area that is outside the inner wall of the pipe socket. In addition, the interior of the pipe socket is advantageously kept free.

Further details, features and advantages emerge from the following Description of an exemplary embodiment shown in the drawing Show it:

FIG. 1: a schematic plan view and FIG. 2: a side view.

In the present example, a heating circuit distributor is one in a box compact unit housed with cover 12. But this is not an emergency agile requirement.

The connection to a collective heater is made with a flow pipe 20 and a return pipe 22. The flow can be separated from a shut-off element 24 and the return can be separated from a shut-off element 28. As in the introduction explained, the innovation is an improvement for a heating circuit distribution system in which the flow and return flow in In the form of a pipe socket, the individual heating circuits can be branched off directly or fed back in via adjustable organs. At the end of the pipe socket a vent 26 or 30 can be arranged. However, it is essential that for the organs, branches or branches in the pipes 20 and 22 at

offset by 180 ° and thus opposite openings in one plane are provided. In the present embodiment, over the flow pipe 20 are adjustable by hand and under the return 22 by means of a tool adjustable organs assigned. This assignment can also take place in other ^ ways.

From the flow pipe 20, individual heating circuit flows 32 branch off, their heating medium is returned via a respective return pipe 40 after passing through the individual heating circuit. The connections are detachable. That The tube or the hose 32 and the tube 40 have a screw connection 34 that fits onto an insert 36. The insert 36 is in the tube 20 and 22, respectively screwed in tightly.

This insert 36 forms a valve seat with a passage opening 42 which is only interrupted by a few radial webs, with the aid of which a central guide 44 is supported. In the pipe 20 a correspondingly shaped part 44 is in the r \ guide of a valve body 46, the sealing ring can close the opening 42nd The valve body is connected to a thin solid shaft, the axis of which is aligned with the guide 44. This shaft 50 traverses the cross section of the tube 20 and, under the action of a spring 54, strikes against a stop 56 in the adjusting knob. The adjusting knob 60 can be rotated relative to a stand via a thread 58. The stand is firmly connected to the parts which are screwed tightly at the top in the tube 20 and which form the insert which is arranged opposite the insert 36 offset by 180 °. When turning the adjusting knob, the valve body 46 is raised or lowered over the shaft 50, and the valve is opened or closed.

The screw is movable in the thread of an insert 72 and its rotation effects the adjustment of the valve. The thread for screw 70 is
