Definitions

• the invention relates to an adapter fitting for the optional connection of a radiator to the inlet and return pipe of a one-pipe or two-pipe heater, with a housing in which two channels are provided, one of which is a connector for releasable connection of the inlet pipe with a connector for detachable Connects the inlet opening of the radiator or a valve leading to it, whereas the other channel connects a connector for the detachable connection of the return pipe with a connector for the detachable connection of the outlet opening of the heater or a valve connected thereto, and a shut-off valve in each of these channels is provided, and wherein there is a connecting channel connecting the two channels, in which a regulating and shut-off valve is located, the two shut-off valves being operable independently of one another and from the regulating and shut-off valve.
• 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 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.
