Embodiment Construction

[0011] See attached picture.

[0012] There are horizontal windows and vertical windows on the vacuum chamber shell of the superconducting tokamak nuclear fusion device. The neck tube 1 is installed on the horizontal window and the vertical window. It is characterized in that there are two sections of bellows 2 on the neck tube. , there is a hard pipe 3 between the two sections of bellows 2. Each section of the corrugated pipe 2 has 10 corrugated nodes, the thickness of the corrugated pipe 2 is 1 mm, and the length of the rigid pipe 3 is 200 mm.

[0013] Optimization of hard tube length between window neck bellows:

[0014] Take 10 waves for each section of the bellows in the vertical window, and establish the finite element analysis model of the window neck tube. Displacement boundary conditions (displacement along the radial direction of the large ring is 15mm, upward displacement along the direction of the neck tube of the window is 15mm), and then the length of the hard ...

Abstract

This invention discloses a window neck tube structure of a special superconductive Tokamak nuclear fusion device vacuum chamber, including a shell of the vacuum chamber, in which, the chamber includes a level window and a vertical window installed with neck tubes on them characterizing that said neck tubes have two sections of ripple tubes and a hard tube between the two sections of ripple tubes, thus the chamber can absorb heat distortion effectively and the neck tube keeps linearity along the axial direction so as to guarantee the normal work of some diagnosis devices.

Description

technical field [0001] The invention belongs to a component of a superconducting tokamak nuclear fusion device, in particular to a neck tube structure of a special horizontal window and a vertical window of the superconducting tokamak nuclear fusion device. Background technique [0002] The superconducting tokamak device vacuum chamber is an ultra-high vacuum container with complicated structural design and processing technology among similar devices. It is one of the "heart" components of the device host and the direct place for plasma operation. Physics, plasma physics, mechanics, vacuum and mechanics and other disciplines, according to the requirements of physical experiments, there are many horizontal and vertical windows on the vacuum chamber body, which are used for diagnosis, heating, pumping, gas charging, cooling, etc. A common feature is that the end face of the window flange is far away from the center of the device, and the operating temperature of the vacuum cha...
