Sealing device for a device for measuring the fill level in a fluid container |
摘要 |
A sealing device for a device for measuring a fill level in a fluid container, particularly in a pressure container of a nuclear facility, includes at least one thermocouple which is connected by a pressure pipe to the pressure container and a pipeline connected to the pressure pipe to an evaluation unit. The pressure pipe and the pipeline are connected to each other by a pipe screw connection including a central part having two threaded pieces. One threaded piece is connected by a screw connection to a pipe sleeve and the other threaded piece is connected by a further screw connection to the pressure pipe. |

1. A device for measuring a fill level in a pressurized fluid container, the device comprising:
a pressure pipe guided out of the fluid container; a thermocouple constructed as a mineral-insulated cable and disposed at least partly in said pressure pipe; a pipe sleeve soldered in a partial section to said thermocouple and surrounding said thermocouple; a sealing device being effective as a pressure barrier, said sealing device having a connection element with a central part encompassing said pipe sleeve and being supported on said pipe sleeve and a connection piece disposed at a first side, protruding laterally and encompassing said pressure pipe; said connection element having a connection piece on a second side remote from said connection piece on the first side, said connection piece on the second side encompassing said pipe sleeve and abutting against said pipe sleeve in a contact region; said pipe sleeve being spaced apart from said thermocouple in said contact region by an annular gap; a screw connection connecting said connection piece on the first side to said pressure pipe; and said pressure pipe being spaced apart from said pipe sleeve and from said thermocouple by an annular gap. |
