Clamping chain type connecting device for large-diameter vacuum flange butt joint

Abstract

The invention discloses a clamping chain type connecting device for large-diameter vacuum flange butt joint. The clamping chain type connecting device comprises multiple arc-shaped clamped connectingblocks, the adjacent clamped connecting blocks are hinged to each other, the clamped connecting blocks are sequentially connected end to end to form a ring, the inner diameter of the ring is smaller than the vacuum flange diameter, and the outer diameter of the ring is larger than the vacuum flange diameter. Trapezoidal grooves are formed in the inner walls of the clamped connecting blocks, the clamped connecting blocks are clamped between two flanges through the trapezoidal grooves, and the head-end clamped connecting block and the tail-end clamped connecting block of the connecting device are detachably connected. After one fastening sleeve is unscrewed remotely through an internal hexagonal wrench, the whole connecting device can be dismounted from the flanges, operation is simple and convenient, the dismounting time is greatly shortened, dismounting safety is improved, and radiation pollution is reduced; and the device can be suitable for connecting flanges with different pipe diameters, after dismounting, the size is small, and the occupied space is small.

Description

technical field [0001] The invention belongs to the technical field of vacuum equipment, and in particular relates to a clip-chain connection device for large-diameter vacuum flange butt joints. Background technique [0002] Generally, the high-vacuum flange connection uses a knife-edge copper gasket for sealing, or adopts the design of a sealing groove and a rubber sealing ring. The above-mentioned structure requires more screws to be installed, and the installation and disassembly are time-consuming and laborious. Moreover, after the accelerator has been running for a period of time, radiation-containing substances fall into the pipes and flanges, resulting in high radiation levels on the surface of the material, posing safety hazards, and the flanges cannot be disassembled at close range. Contents of the invention [0003] The present invention provides a clip chain connection device for butt jointing of large-diameter vacuum flanges, aiming at solving the above-mention...

AI Technical Summary

Problems solved by technology

[0002] Generally, when connecting high-vacuum flanges, use knife-edge copper gaskets for sealing, or adopt the design of sealing grooves to press rubber sealing rings. The above structure requires more screws to be installed, and installation and disassembly are time-consuming and laborious.

And after the accelerator runs for a period of time, the radiation-containing substances fall into the pipe and flange, resulting in high radiation on the surface of the material, which poses a safety hazard, and the flange cannot be disassembled at close range
