A combined bursting disc composed of a metal diaphragm with a slit on the arch surface and a sealing film. Bursting pressure is controlled by a weakened structure formed by slits and holes on the arch surface of the metal diaphragm. When in use, the concave surface contacts the medium, and the convex surface faces the relief side. When the system is overpressured, the rupture disc is stretched and broken along the weak link to release the pressure, thereby protecting the safety of the system.

 

the main form:

 

1. Positive arch slotted rupture disc LF: suitable for occasions that can withstand back pressure or no back pressure and vacuum

 

2. Positive arch slotted bursting disc LFT: suitable for occasions that need to withstand vacuum or back pressure
