| titleOfInvention | Thermally insulated bellows expansion device |
| abstract | The utility model relates to pipeline technology, and in particular to devices used in pipelines of a heating network for channelless pipelines. The bellows expansion device for a pipeline with thermal insulation contains a metal bellows compensator (1) of axial displacements, one-piece connected on both sides with nozzles (3) and (4), enclosed in a metal protective casing (2), covered by a waterproof pipe-sheath (5) connected to the corrugated portion (9). The wires of the operational-remote control system (7) run along the entire length of the compensator. The device is equipped with an additional waterproof pipe-sheath (14) mounted on the pipe (4) behind the bellows compensator (1) and fastened to the corrugated section (9), in which a metal shell (13) is enclosed, mounted on the support rings (12). Polyurethane foam insulation (15) is placed in the space between them. Both shell pipes (5) and (14) are made of a polymer material with reinforcement from a steel casing from the inside. The protective casing (2) through the metal ring (6) is on one side inextricably connected to the pipe (3) located in front of the bellows expansion joint. On the other hand, the casing (2) rests on the guide support ring (11), one-piece connected to the pipe (4) located behind the bellows compensator (1). The casing over the corrugated section (9) is made in the form of a polyethylene heat-shrink sleeve (10), connected on the one hand with an additional waterproof pipe-sheath (14) and, on the other hand, installed with free movement along the pipe-sheath (5). Under the corrugated section (9) made of a polyethylene sheath pipe, between the guide support ring (11) and the support metal ring on the nozzle (4), thermal insulation from technical felt (16) is fixed, and the thermal insulation of the bellows compensator (1) is made using thermal insulation material (8). The wires (7) of the operational-remote control system are located in a plastic perforated cambric. EFFECT: improved operational properties of the device, increased reliability and availability. 1 ill. |
