Fragmentation-free and low-flow-resistance high-pressure anti-arch cross recess rupture disk clamping structure

Abstract

The utility model discloses a fragment-free and low-flow-resistance high-pressure anti-arch cross recess rupture disk clamping structure, which relates to the technical field of rupture disks and comprises an upper clamping device, an anti-arch cross recess rupture disk component and a lower clamping device. An inner cavity of the upper clamp holder is of a big-end-down gradually-shrinking structure, after the rupture disk acts, the cracking part of the rupture disk firstly impacts a diameter-shrinking inclined face to be forcibly folded inwards, and root tearing and fragment flying out are prevented. The arch face of the rupture disk protrudes downwards, the upper clamp protruding ring and the lower clamp protruding ring form an annular flow channel, and the rupture disk is attached to the hole shrinkage inclined face after being turned up without blocking the flow channel. Main parts are processed by conventional stainless steel forgings, expensive materials or complex processes are not needed, and the economical efficiency is good; the utility model discloses a multi-dimensionality such as high pressure, no fragment, low flow resistance, easy maintenance surpasses the prior art comprehensively, can be widely applied to hydrogenation reactor, high pressure storage tank, supercritical fluid pipeline and other key occasion, has obvious economic benefit and social benefit.
