Connection for a heating body comprises a seal support separately inserted into a pipe connector and housing, supporting and partly forming a seal

摘要

Heating body connection (1) comprises at least one pipe connection (2, 3) provided with an externally actuated shut-off element (5) and at least one pipe connector (9). The shut-off element is loaded and sealed in the region of the pipe connector by a seal (10) arranged in the pipe connector. A seal support (14) separately inserted into the pipe connector houses, supports and/or at least partly forms the seal. The shut-off element which is opened and closed by rotation has counter stops on its periphery adjacent to the seal and to its sealing region and to an opening (11) within the sealing region for the heating medium. The distance between the counter stops in the peripheral direction corresponds to the length of the adjustment path or adjustment angle between the open and closed position. The seal support has a stop (17) interacting with or protruding between the counter stops.
