A combined bursting disc composed of a metal diaphragm and a sealing film slit on a plane. Bursting pressure is controlled by a weakened structure formed by slits and holes on the plane of the metal diaphragm. When the system is over-pressured, the rupture disc is stretched and broken along the weak link to release the pressure.
The bursting disc has the advantages of large discharge area, good sealing performance, low burst pressure, sensitive action, safety and reliability. Widely used in: dust processing industries such as coal, mineral powder, medicine, fertilizer, plastics, grain, pigment, fiber, textile, etc., to protect storage silos, silos, dust collectors, air conveying equipment, dryers and other equipment.
Main types:
1. Round flat slotted rupture disc LF: suitable for situations without back pressure and vacuum
2. Round flat slotted rupture disc with bracket LFT: suitable for occasions that need to withstand vacuum or back pressure
3.Square flat slotted rupture disc LFF: suitable for situations without back pressure and vacuum
4.Square flat plate slotted rupture disc LFFT with bracket: suitable for occasions that need to withstand vacuum or back pressure
