Abstract
An improved composite rupture disk assembly adapted to be supported between inlet and outlet supporting members is provided. The assembly is comprised of a resilient sealing member and a rupture member having a plurality of elongated openigs formed therein which extend outwardly from a central portion thereof. At least one rupture pressure determining score is formed in the rupture member connecting the inner ends of two or more of the elongated openings so that rupture of the composite assembly occurs when pressure is exerted on the sealing member and transmitted to the rupture member at a level equal to or exceeding the rupture pressure of the rupture member.
Claims20
In a composite rupture disk assembly adapted to be supported between inlet and outlet supporting members which includes a resilient sealing member and a rupture member having a plurality of elongated openings formed therein, the rupture member being positioned adjacent the sealing member whereby rupture takes place when pressure exerted on the sealing member and transmitted to the rupture member reaches a predetermined rupture pressure, the improvement which comprises said rupture member having at least one rupture pressure determining score formed therein connecting the ends of two or more of said elongated openings.
A rupture member for use in a composite rupture disk assembly which includes a resilient sealing member comprising a substantially circular section of thin rigid material having a plurality of elongated openings formed therein and having at least one rupture pressure determining score formed therein connecting the ends of two or more of said elongated openings so that rupture of said rupture member occurs when pressure transmitted to said rupture member reaches a level equal to or exceeding said rupture pressure.
