The present invention relates to an improved fluid pressure relief apparatus, and more particularly, but not by way of limitation, to a fluid pressure relief apparatus of the rupture disk type wherein the rupture disk includes scores on a surface thereof.
,: .
The present invention relates to an improved fluid pressure relief apparatus, and more particularly, but not by way of limitation, to a fluid pressure relief apparatus of the rupture disk type wherein the rupture disk includes scores on a surface thereof.
2. Description of the Prior Art A variety of fluid pressure relief apparatus of the rupture disk type have been developed and used. Generally, :~
such apparatus include a rupture disk supported between lnlet and outlet supporting membe.rs whereby fluid pressure within a vessel or system to be protected is exerted on the rupture disk by way of the .inlet supporting member. When the 1uid pressure exceeds the design rupture pressure of the disk, rupture occurs causing fluid pressure to be ., relieved through the outlet supporting member. Heretofore, some of such rupture disks have included scores or grooves formed therein which define lines of weakness so that upon rupture, the disks tear along the lines of weakness. While the score patterns heretofore used on rupture disks have served to reduce ~ra~mentation oE the disks upon rupture, some fragmentation still occurs primarily due to tearing of the disk material in areas where lines of weakness created by the scores do not exist. Also, because of the tearing of prior disks in unscored areas, portions of the disks often extend into the resulting pressure relief area reducing the flow of fluids therethrough.
By the present invention, a fluid pressure relief apparatus is provided which includes a rupture disk having an . 2 .. . . ... ....... . .

improved score pattern whereby upon rupture fr~gmentation is substantially eliminated and full opening is achieved.
SUMMARY OF THE INVENTION
The invention provides a rupkure disk comprising a sheet of rupturable material clampable between a pair of annu-lar support members and having at least three scores on a surface thereof defining lines of weakness radiating from the centre of the disk, each score including a main portion radi-ating out from the centre of the disk, each main portion being provided with two additional divergent score portions diverging from the outer ends of the main score portions.
~ Preferably the main portions of the scores are straight and the additional divergent portions are curved, pre~
ferably being arcs with their convex sides facing the disk periphery. Preferably the disk comprises a peripheral Elat 1ange portion and a central concave-convex domed portion con-nected to the flange portion by a transition connection, and additional divergent score portions terminate at their outer ends radially inwardly of the transition connection. The scores may be on the concave or the convex surEace oE the disk. Pre-ferably there are four main score portions.
Other and further objects, Eeatures and advantages oE the present invention will be readily apparent to tho9e skilled in th~ art upon a reading oE th~3 Eollowin~ doscription of presently preferred embodiments of the invention, given for the purpose of disclosure, and taken in conjunction with the accompanyin~ drawin~s.

Description of Preferred Embodiments Referring now to the drawings and particularly to FIGURES
1 and 2, the improved fluid pressure relief apparatus of the present invention is illustrated and generally designated by the numeral 10. The apparatus 10 basically comprises an inlet sup-porting member 12, an outle~ supporting member 14 and rupture disk 16. The rupture disk 16 is sealingly clamped between the inlet and outlet supporting members 12 and 14 by a plurality of cap screws 18 positioned around the peripheral portions o~ the sup-porting members. As is well understood by those skilled in the art, the supporting members 12 and 14 can take a variety of shapes.
For example, the supporting members can be flanges which are adapted for welding or threading, or the supporting members can be adapted for clampllng between conventional pipe 1anges or between other clamping members.
~s will be further understood by those skille~ in the art, the rupture disk 16 can take a variety of forms and shapes.
I~ the embodiment illustrated in the drawings, the rupture disk 16 includes a concave-convex central portion 20 connected to an annular flat flange portion 22 by a transition connection 24. In this form, the annular flat flange portion 22 of the rupture disk 16 is clamped between complementary annular flat seatlng surfaces provlded on the supporting members 12 and 14 so that the rupture disk 16 is sealingly ~7~ 6i6 :, .
supported between the members 12 and 14. However, the rupture .:
disk 16 can be entirely flat or entirely concave-convex, or instead of the annular flat flange portion 2~ and the comple-mentary flat annular seating surfaces on the supporting members 12 and 14, other seating shapes and arrangements can be utilized. ~ ~
In the form illustrated in the drawings, the rupture disk 16 `~ :
is a reverse buckling disk. That is, the convex side of the ;:~:
concave-convex portion 20 of the disk 16 is positioned facing the inlet supporting member 12 so that when the fluid pressure exerted on the convex side of the disk 16 exceeds the pressure at which the disk is designed to fail, the concave-convex portion 20 reverses itself and rupture occurs. In order to create lines of weakness in the concave-convex portion 20 o~
the disk 16 so that after reversal the concave-convex portion 20 tears along such lines of weakness and opens in a prede-termined manner, a pattern 26 of scores or grooves is formed in the concave-convex portion 20. As is again well understood by those skilled in the art, the score pattern 26 can be positioned on either the convex or the concave side o~ the çoncAve-convex portion 20, and can be used for creaking lines of weakness in either reverse buckling rupture disks or rupture d~sks that operate in the conve.ntional manner, i.c., disks whereby ~luid pressure is exerted on the concave side of the concave-convex portion 20 rather than the convex side thereof.
Scores have heretofore been used to create lines of weak-ness in both reverse buckling and conventional rupture disks and to thereby control the mode of rupture. That is, the lines of weakness cause the disk to open in a predetermined pattern and reduce the number and incidents of loose pieces tearing ~ .
away from the disk. ~Iowever, prior to the present invention, ~ 7~6~ :
problems with loose pieces tearing away from scored disks have still occurred, primarily because the disks often tear in areas which do not contain scores and, in addition, less than full openlny often occurs due to portions of the disk extending S into the pressure relief area. By the present invention, an improved score pattern is provided which substantially eliminates fragmentation upon rupture of the disk and brings about full opening. As best shown in FIGURE 2, the improved score pattern of this invention basically comprises four scores 28 which radi~te outwardly from a central portion 32 of the concave-convex portion 20 of the disk 16 and extend toward the tran-sition connection 24 thereof. The ends 36 of the scores 28 each connect with a pair of curved scores 42 and 44 forming ~ -a V-shape. That is, the exterior ends of the scores 28 each connect to the apex of a V-shape formed by curved scores 42 and 44. Each of the scores 42 and 44 are curved in a direction such that the convex sides of the scores face the transition connection 24 of the rupture disk 16. As shown in the drawings, straight scores 28 are preferred positioned at right angles to each other thereby dividing the concave-convex portion 20 of the rupture disk 16 into quadrants. However, three scores 28 dividing the concave-convex portion 20 into three parts, or more than four scores 28 can be utilized if desired so long as each of the exterior ends thereof connect with scores forming V-shapes as described above. In addition, opposite scores 28 can be continuous across the central portion 32 so that two or more intersecting scores are utilized.
As illustrated in FIGURE 3, in operation of the apparatus 10, i.e., when the disk 16 of the apparatus 10 ruptures, the concave-conve~ portion 20 thereof reverses itself and then tears ~37~
along the lines of wea~ness created by the scores 28, 42 and 44 forming our lar~e petals generally designated by the numeral 46 and four small petals generally designated by the numeral 48. The central portion 32 remains attached to one of the large petals 46. Because scored rupture disks developed and used prior to the present invention have not included lines of weakness corresponding to the scores 42 and 44, and upon rupture of such disks uncontrolled tearing of the disk material occurs in such areas, loose pieces of the disk can be and are often produced and full opening is not achieved.
The improved score pattern of the present invention creates lines of weakness in the rupture disk everywhere that tearing occurs during rupture thereby eliminating uncontrolled tearing and formin~ large and small petals 46 and 48 which are all lS bent upwardly out of the pressure relief area whereby full opening is achieved.
Thus, the present invention is well adapted to carry out the objects and attain the ends and advantages mentioned as well as those inherent therein. While presently preferred embodiments of the invent.ion have been described for the purposes o~ this disclosure, numerous chan~es in the :Eorm and a.r~an~ement of the parts o:~ the lnvention can be made by those s~illed in the art, which changes are encompassed within the spirit of this invention as defined by the appended claims.
