Novel clamping device capable of fast mounting and dismounting rupture disc device

Abstract

The invention discloses a novel clamping device capable of fast mounting and dismounting a rupture disc device. The clamping device comprises a first clamping unit, a second clamping unit, two groupsof electromagnets and two glands. Annular grooves are formed in the back faces of the first clamping unit and the second clamping unit correspondingly. Counterbores are formed and distributed in the annular grooves correspondingly. The two groups of electromagnets are placed into the corresponding counterbores. The two glands are placed into the corresponding annular grooves and used for fixing the electromagnets correspondingly. The winding directions of wires of the two groups of electromagnets in the first clamping unit and the second clamping unit are opposite, and the two groups of electromagnets are opposite in magnetism during working; and the groups of electromagnets are connected in series by adopting the wires. Different from a clamping device using bolts for connection, the novel clamping device has the advantages that a brand-new design concept is adopted, an electromagnet working principle is introduced, the purpose that rupture discs are mounted and dismounted is achievedby adjusting the current size through a control module, the operating time is greatly reduced, and the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of safety equipment, in particular to a novel holder that can quickly assemble and disassemble a bursting disc device. Background technique [0002] In a large pressure vessel device like a tokamak, it is often equipped with an overpressure protection system. The bursting disc device is a commonly used pressure relief component in the overpressure protection system, and the holder is an important part that connects the bursting disc with the pipeline. , the commonly used connection is flange connection. The existing flange connection uses bolts to make the two holders clamp the bursting disc assembly. However, as the pipe diameter increases, the number of bolts will also increase. It is time-consuming and laborious to disassemble the rupture disc; and the bolts may be lost; and due to long-term corrosion, the holders may have rusted to death, making it difficult to disassemble and repair; at the same time, f...

Problems solved by technology

[0004] The invention provides a new type of holder that can quickly assemble and disassemble the bursting disc device, which is used to solve the problem of screwing a large number of bolts when the bursting disc is connected and disassembled in the existing tokamak device, which is time-consuming and labor-intensive, and the bolts are pre-tightened. Force can not be precisely controlled and other issues
