Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is an overall structure cross-sectional schematic of the present invention
Fig. 2 is a plan structure schematic representation of the present invention.
Among the figure, 1, the rupture disk fixed edge, 2, the rupture disk stiffness region, 3, the rupture disk connection area, 4, weaken groove, 5, explosion cracking district, 6, rupture disk cutting district not.
Embodiment
The self-holding burst disc without fragment of explosion status not, expandable explosion cracking district 5 after the explosion, by with weaken not cutting district 6 of rupture disk that groove 4 is in same circumference, link to each other with rupture disk connection area 3, rupture disk connection area 3, rupture disk stiffness region 2 and rupture disk fixed edge 1 link to each other successively.Angle α between rupture disk stiffness region 2 and the rupture disk fixed edge 1 is 92 °.Does the non-radioactive shape weaken the angle crusty pancake at groove 4 two end part roots and center? 5 °.The rupture disk material is stainless steel OCrl8Ni9, adopts the machining mode, forms the each several part of rupture disk.
Rupture disk is by rupture disk fixed edge 1, with the relief hole edge of protected container or protected container relief tube, directly or indirectly contact, can by weld, be threaded, method such as bolt clamping links to each other with protected container.
