Ultrahigh pressure rupture disk safety release device

Abstract

The invention provides an ultrahigh pressure rupture disk safety release device with pressure bearing capacity of more than or equal to 100 MPa, good sealing performance and stable operation by utilizing a Levy Mises increment theory and a powerful moment theory, and aims at solving the problem of the loss of the design structure of the ultrahigh pressure rupture disk safety release device and filling the gap of the ultrahigh pressure rupture disk structural design in China. In order to realize the purpose, the ultrahigh pressure rupture disk safety release device is designed and is suitable for different use occasions. The ultrahigh pressure rupture disk safety release device is divided into three structural types, namely, a split type ultrahigh pressure rupture disk safety release device, a welding type ultrahigh pressure rupture disk safety release device and a suspension type ultrahigh pressure rupture disk safety release device. The split type ultrahigh pressure safety release device comprises an upper clamp holder, a pressure ring, an ultrahigh pressure rupture disk, a self-tightening lens sealing ring and a lower clamp holder; the welding type ultrahigh pressure rupture disksafety release device comprises an upper clamp holder, an ultrahigh pressure rupture disk and a lower clamp holder; and the suspension type ultrahigh pressure rupture disk safety release device comprises an upper clamp holder, an ultrahigh pressure rupture disk assembly and a lower clamp holder. The design structure solves the problem of the deficiency of an existing ultrahigh pressure containersafety release device, and also forms the last barrier of the ultrahigh pressure container safety protection, thereby avoiding the dangerous situation of the medium storage and the use in the ultrahigh pressure container, improving the safety performance and facilitating the unified management.

Description

technical field [0001] The invention relates to the technical field of safety protection of ultra-high pressure pressure vessels and other chemical equipment, in particular to a safety release device for ultra-high pressure bursting discs. Background technique [0002] Pressure vessels are generally divided into four categories according to pressure. The pressure is 1MPa-1.6MPa for low-pressure vessels, the pressure is 1.6MPa-10MPa for medium-pressure vessels, the pressure is 10MPa-100MPa for high-pressure vessels, and the pressure is above 100MPa for ultra-high pressure vessels. . The bursting disc safety device is a non-reclosing pressure relief device. At the set blasting temperature, when the pressure difference on both sides of the bursting disc reaches a predetermined value, the bursting disc will act immediately to discharge the gas medium in the container and reduce the pressure. , to prevent catastrophic overpressure of chemical containers, and to avoid major safet...

AI Technical Summary

Problems solved by technology

The design and selection of bursting discs need to comprehensively consider the influence of factors such as the use occasion, bursting disc type, bursting disc material, design blasting temperature, and design blasting temperature. Although scholars at home and abroad have done a lot of academic research on bursting disc safety release devices However, most of them are based on the thin-walled spherical shell membrane theory and the equal-thickness spherical shell theory. The method and structural design of the bursting disc safety relief device with a pressure less than 100 MPa have not yet proposed any design structure to solve the ultra-high pressure with a pressure exceeding 100 MPa.
