Pipe sample tensile fixture

Abstract

The utility model relates to the technical field of clamps, in particular to a pipe sample tensile clamp, which is characterized in that the bottom of a sample is sealed by adopting an in-pipe support and a sealing joint for locking, the upper part of the clamp is sealed by a hollow support and a clamping sleeve, and the inside of a zirconium pipe sample can be pressurized through the hollow support; high-pressure-bearing sealing of the interior of the zirconium tube sample in a high-temperature environment is realized; the upper clamping block and the lower clamping block are adopted, the clamping blocks are conical, clamping is convenient, supports are arranged at the positions, corresponding to the clamping blocks, in the pipe sample, clamping is completed through pressing of the pressing blocks, the whole sample can be taken out after the two clamping blocks are taken out when the sample is disassembled, and the sample is convenient to replace; the wall thickness of the zirconium tube sample is too thin, and the two tube sample supporting pieces are added to facilitate clamping and sealing of the sample.
