KR-20260067874-A - Pressure-Relief Rupture Plate with Multi-Gasket of Different Materials

Abstract

A pressure relief rupture disc comprising a multi-gasket made of different materials according to one embodiment is a pressure relief device having a structure in which a portion ruptures to safely discharge pressure to the outside when the pressure inside a pressure vessel exceeds a set rupture pressure, and comprises a main disc having a rupture portion formed therein, a support disc having a plurality of through holes formed therein and in contact with the fluid inside the pressure vessel located below the main disc, a sealing sheet located between the main disc and the support disc to prevent fluid leakage, an upper gasket located radially outward from the rupture portion above the main disc, and a lower gasket located radially outward from the through holes below the support disc.

1. As a pressure-releasing rupture disc, In a rupture disc designed to rupture in order to safely release pressure to the outside when the overpressure inside a pressure vessel exceeds a set rupture pressure, A main disk (210) comprising a rupture portion (220) formed of an arc-shaped cut slit and cut holes on both sides so as to rupture when the above-mentioned overpressure exceeds a set rupture pressure, which opens based on the hinge portion (215) upon rupture to disperse the rupture impact, and A support disk (240) that contacts a fluid at a lower side than the main disk (210) and has a plurality of through holes (245a, 245b) formed therein, and A sealing sheet (230) disposed between the main disk (210) and the support disk (240) to prevent fluid leakage, and An upper gasket (250) located radially outward from the rupture portion (220) on the upper side of the main disk (210), and It includes a lower gasket (260) located radially outward from the through holes (245a, 245b) on the lower side of the support disk (240), and The upper gasket (250) and the lower gasket (260) are composed of different materials, and the lower gasket (260) is made of a material with higher corrosion resistance than the upper gasket (250) so as to be able to operate stably even in high temperature and corrosive environments. The main disk (210) comprises a plurality of rupture portions (220), wherein the plurality of rupture portions (220) are spaced apart in the circumferential direction, and the spacing between each rupture portion (220) is designed to become shorter as it moves further away from the hinge portion (215) to sequentially mitigate the impact force upon rupture. A pressure-releasing rupture disc characterized by additionally including a rupture detection sensor in the main disk (210) above, so as to be able to detect and monitor in real time whether the rupture portion (220) is ruptured.

Description

Pressure-Relief Rupture Plate with Multi-Gasket of Different Materials Pressure-Relief Rupture Plate with Multi-Gasket of Different Materials The present invention relates to a rupture disc used as a pressure safety device for various industrial equipment, and in particular to a structure that enables the rupture disc to operate effectively under pressure conditions exceeding the normal pressure range through a multi-gasket structure composed of dissimilar materials. Conventional rupture discs are designed to release pressure to the outside by rupturing at a specific point when overpressure occurs inside a pressure vessel and exceeds a set rupture pressure. Such rupture discs are primarily used in various industrial fields, including chemical processing, semiconductor manufacturing, and high-pressure gas storage devices. In particular, in semiconductor processes, various reaction gases are supplied at high pressure, and rupture discs are used to prevent damage to pressure vessels during this process. The problem with existing rupture discs is that they rupture at high speed and generate fragments when overpressure occurs, or the gasket deteriorates due to prolonged use. This has resulted in a shortened lifespan of the rupture disc or a risk of safety accidents.
