Metal wire sealing and leading-out device applicable to experiment kettle

Abstract

The invention provides a metal wire sealing and leading-out device applicable to an experiment kettle. The device comprises a radiating tube, separators, a conical sealing plug and a fastening assembly, wherein one end of the radiating tube is connected with the experiment kettle through a mounting hole of the experiment kettle, the other end corresponds to the conical sealing plug, and the conical sealing plug is circumferentially connected with the radiating tube through the fastening assembly in a sealed manner; at least one separator is arranged in a central channel of the radiating tube, through holes corresponding to metal wires led out of the experiment kettle are formed in the conical sealing plug and the fastening assembly, at least two metal wires extend from the experiment kettle and sequentially penetrate through the central channel of the radiating tube, the conical sealing plug and the fastening assembly, and the metal wires are separated from one another by the separators in the central channel of the radiating tube. Pressing force is realized by the aid of a pressing cover and a pressing sleeve, rotation of the pressing sleeve is prevented by the aid of rotation preventing parts such as pins, and the device is simple in structure and easy to operate.

Description

technical field [0001] The invention relates to a wire sealing drawing-out device suitable for an experimental kettle. Background technique [0002] The DCPD measurement method has been widely recognized and used in the study of the fatigue crack growth rate of metal materials in the high temperature and high pressure corrosive medium environment. However, in most cases, metal materials are still tested in the air environment at room temperature, which cannot fully simulate the working conditions of the material for materials in high-temperature and high-pressure corrosive medium environments, and the test results often cannot reflect its reality. usage. The high-temperature and high-pressure test kettle can provide adjustable test temperature and pressure, as well as a medium environment similar to actual working conditions, which provides strong environmental support for testing materials in corrosive medium environments. [0003] To test the performance of metal materia...

AI Technical Summary

Problems solved by technology

Since the metal wires used are relatively thin and generally have a wire diameter of less than 1mm, it is difficult to achieve sealing with conventional sealing methods; moreover, several metal wires are often drawn out at the same time. If a separate sealing device is designed for each wire, it will inevitably will take up a lot of space
