As a safety device with unique structural advantages, low pressure rupture disk relies on the combination of reverse arch surface design and knife-type rupture mechanism to show excellent performance in the field of overpressure protection. The burst pressure of low pressure rupture disk is accurate and stable, the response speed is fast, and the fatigue resistance is strong. It can adapt to a variety of complex working conditions. It is widely used in petrochemical, new energy, pharmaceutical engineering, metallurgical industry and other industries to provide reliable overpressure relief protection for all kinds of pressure equipment.
High-pressure reaction devices and pipeline systems in the petrochemical industry have high requirements for the pressure resistance of rupture discs. In wellhead devices for crude oil extraction, facing the characteristics of large formation pressure fluctuations, sand-containing media and corrosive components, the reverse arch structure can effectively resist fatigue damage under high pressure, and the knife-type cutting mechanism allows the low pressure rupture disk to rupture instantly during overpressure, avoiding the risk of blowouts caused by wellhead overpressure. In the hydrogenation reactor and catalytic cracking unit of the refining and chemical plant, the high temperature and high pressure environment has strict requirements for the stability of the material and structure of the rupture disc. low pressure rupture disk adopts high-temperature and high-pressure materials, combined with precision tool groove design, which can maintain burst pressure under extreme operating conditions and provide precise protection for reactors, separators and other equipment. In addition, the low pressure rupture disk has the characteristics of strong deformation resistance of the reverse arch surface, which is particularly suitable for handling working conditions containing solid particles or viscous media, which can reduce the performance attenuation caused by media deposition.
The special process environment in the production of new energy and new materials provides application space for low pressure rupture disk. In the high-temperature sintering furnace and inert gas protection reactor for the preparation of lithium battery materials, the rupture disc is required to have excellent air tightness and temperature resistance. The reverse arch surface of the low pressure rupture disk fits closely with the sealing surface, and the leakage rate is low, which can meet the sealing requirements of the inert gas atmosphere. At the same time, the knife-type structure of the rupture disc is not affected by the temperature cycle, and stable blasting performance can be maintained in a wide temperature range. In the chemical vapor deposition equipment produced by photovoltaic materials, low pressure rupture disk can effectively solve the problem that traditional rupture discs are prone to fatigue failure under alternating vacuum and pressure conditions.
The clean production requirements and complex media characteristics in the fields of medicine and fine chemicals make low pressure rupture disk an important safety component. In the sterile reaction tanks and fermentation equipment of biopharmaceuticals, the low pressure rupture disk knife-type rupture has no characteristics of debris generation, which can effectively prevent debris from contaminating materials after blasting and ensure the quality and safety of medicines. In the production equipment of dyes and coatings in fine chemicals, facing corrosive media such as organic solvents, strong acids and alkalis, low pressure rupture disk enhances corrosion resistance and extends service life through surface passivation treatment or PTFE coating technology. At the same time, the fast response characteristics of low pressure rupture disk can effectively cope with the instantaneous overpressure that may occur in the polymerization reaction and avoid the occurrence of explosive polymerization accidents.
