A pipe connection device for central heating systems can be adapted in a simple manner for use in single-pipe or double-pipe systems which work with radiators or convectors. To this end, the pipe connection device has a housing with a forward run inlet channel, a forward run outlet channel, a branch inlet channel and a branch return channel, as well as a pipe piece arranged in a housing bore. In a single-pipe heating system, a bypass flow is provided between the forward run inlet channel and the forward run outlet channel, along the outside of the pipe piece, while in a double-pipe heating system the bypass flow is prevented by sealing the pipe piece in relation to the housing bore between the forward run inlet channel and the forward run outlet channel. Moreover, an individual radiator can be separated from the heating medium lines simply by actuation of the valve elements of the relevant individual radiator with the aid of an adjustable closure member in the housing. |
