Precision reverse bursting disc is a pressure sensitive element that acts rapidly under overpressure. It is an important safety device to prevent overpressure damage to pressure equipment. It is suitable for slurry, viscous, and corrosive process media. In this case, the safety valve does not work. Precision reverse operating rupture disc has the characteristics of small inertia and can react quickly to sharply increased pressure. Precision reverse operating rupture disc has many specifications and models, can be manufactured from various materials, has strong adaptability, and is easy to maintain and replace.
Key points of safety technology used by precision reverse operating rupture disc:
1. Daily inspection: the user unit should always check the precision reverse operating rupture disc device for media leakage. If the reverse buckling rupture disk is installed in an exposed manner, you should check whether the reverse buckling rupture disk has surface damage, corrosion, and obvious deformation.
2. Regular inspection: the regular inspection cycle of the circular reverse buckling rupture disk device can be specified according to the specific circumstances of the unit used, but the longest period cannot exceed one year. The content of regular inspections includes checking whether the installation direction of the circular reverse buckling rupture disk device is correct, and verifying whether the burst pressure and burst temperature on the nameplate meet the operating requirements. Check the outer surface of the circular reverse buckling rupture disk for corrosion and damage, for obvious deformation, and for foreign matter adhesion and leakage. When the circular reverse buckling rupture disk device and the safety valve are used in series, check the pressure indicator device between the device and the safety valve to confirm whether the circular reverse buckling rupture disk device and the safety valve are leaking. Check whether the discharge pipe is smooth, whether there is serious corrosion, and whether the support is firm. If a shut-off valve is installed between the rupture discs for pressure relief device and the equipment, check whether the shut-off valve is in a fully open state and whether the lead seal is intact.
3. Rupture discs for pressure relief replacement: the replacement cycle of rupture discs for pressure relief should be based on specific influencing factors such as equipment use conditions, media properties, etc., or the design's expected service life is reasonably stipulated. Under normal circumstances, the replacement cycle of rupture discs for pressure relief devices is two to three years. For corrosive, toxic media, and rupture discs for pressure relief devices used under harsh conditions, the replacement cycle should be shortened.
