Beschreibung
Zusammenfassung:	The utility model discloses a positive arch and reverse arch slotted rupture disk combination device which comprises a lower clamp holder, a middle clamp holder, an upper clamp holder, a positive arch slotted rupture disk, a reverse arch slotted rupture disk, a fastener and a pressure measuring zero relief device, and screws sequentially connected with the middle clamp holder are arranged on one side of the interior of the lower clamp holder and one side of the interior of the upper clamp holder. The inverted-arch slotted rupture disk is arranged between the lower clamp holder and the middle clamp holder, and the forward-arch slotted rupture disk is arranged between the middle clamp holder and the upper clamp holder; by adopting a combined structure of the forward-arch and reverse-arch grooved rupture disks, the reverse-arch grooved rupture disk is good in anti-fatigue performance and is placed on the high-pressure side of equipment, the service life of the whole device is prolonged, and the forward-arch groo
