- Such adapter fittings are known (DE-OS 3,934,837). On the one hand, they form a connection piece with which a radiator of any type, e.g. a panel or sectional heater, depending on the circumstances, can be connected to the pipes of a single-pipe heating system or a two-pipe heating system. On the other hand, such fittings make it possible to change the supply system, that is to say to change from a one-pipe heating system to a two-pipe heating system or vice versa, even if the radiators are already installed.
- the two shut-off valves serve to be able to shut off the radiator without obstructing the function of the system, either because the room in which the radiator is located should not be heated, be it for the purpose of replacing the radiator or the like.
- the two blocking valve are constructed as tile Hahne, which, di usually the the supplied turned to 'heated chamber side of the Schu ⁇ body, are operable forth from the front side of the fitting.
- This construction has the disadvantage that the shut-off valves are difficult to access when the valve - for what Reasons always - must be connected rotated by 180 °. It is also disadvantageous that when the connection between the fitting and the heating element is loosened, the water runs out of it, since, as a rule, the waste
- Flow opening for the heating medium from this radiator is arranged at a low point thereof.
- the invention has for its object to avoid these disadvantages and to improve a valve of the type described above so that the actuation of the shut-off valves is always possible and that there is a possibility for a controlled emptying of the radiator in any position of the same, without the operation the other radiators in the system.
- the invention solves this problem in that the two shut-off valves have rectilinearly adjustable closure bodies, in that the adjustment directions of these closure bodies lie in a common plane spanned by the axes of the two connecting pieces to be connected to the heating element or its fitting, and that at least one of the connecting pieces leading to the radiator or its fitting leads to the outside a drainage opening that can be closed independently of the shut-off valves and the regulating and shut-off valve.
- the two shut-off valves can thus be actuated from the two sides of the fitting, so that it does not matter in which position the fitting is connected to the pipes for the heating medium supply.
- the radiator By means of the emptying opening, the radiator can be emptied in a controlled manner when the shut-off valves are closed.
- the water flowing out through this emptying opening can be collected without problems with a suitable vessel or removed in another suitable manner.
- the invention offers the advantage that the fitting can be mounted in both possible positions, so that by selecting this position, the position of the emptying opening is adapted to the position of the outflow opening of the radiator.
- the construction can easily be provided with a drain opening on each of the two nozzles, or two construction variants are provided, one of which has the drain opening on the left nozzle is connected, the other to the right.

- the arrangement is such that the axis of the discharge opening is coaxial with the axis of the associated shut-off valve.
- the two adjusting devices and the axis of the emptying opening are expediently coaxial, preferably horizontal.
- the horizontal, coaxial position makes it possible to maintain the familiar H-shaped basic shape of the valve, although in principle deviations from it would also be possible.
- the invention also makes it possible to eliminate a further disadvantage of the known construction described at the outset.
- This disadvantage consists in the fact that in a single-pipe heating system the water swirls into the radiator even when the radiator valve is closed and thereby heats it more or less, even if the regulating and shut-off valve arranged in the connecting channel is fully open.
- the arrangement according to the invention is such that the valve seat of at least one shut-off valve is arranged in a wall section which is normal to the associated adjustment direction of a wall which penetrates the associated channel and which has a deflection surface for the flow from the associated pipeline Forms heating medium, which directs this heating medium towards the connecting channel.
- a particularly advantageous embodiment of the invention consists in designing at least one of the two closure bodies as a presetting body guided with threads in order to be able to combine the shut-off function with the presetting function.
- Fig.l shows a vertical section through the adapter fitting with the closure bodies in the open position and closed regulating and shut-off valve.
- Fig. 2 shows an analog sectional view of the regulating and shut-off valve in the open position.
