Abstract
A rupturable fluid flow indicator and a rupture disk assembly including the indicator are provided. The indicator is comprised of a rupturable member adapted to be clamped across a fluid flow passageway having at least one opening formed therein for weakening a portion of the member. An electric current conductor adapted to be electrically connected in an alarm circuit is attached across the weakened portion of the rupturable member whereby when the member ruptures as a result of fluid pressure exerted thereon, the conductor also ruptures.
Claims11
A rupture disk assembly which provides an immediate indication of when a rupture disk in the assembly ruptures or fails whereby pressurized fluid flows therethrough comprising:
- a rupture disk adapted to be clamped across a fluid flow passageway and to rupture when a predetermined fluid pressure is exerted thereon;
- an annular spacer positioned on the downstream side of said rupture disk;
- a fluid flow indicator positioned on the downstream side of said annular spacer, said indicator including:
- a rupturable member adapted to be clamped across a fluid flow passageway and having a plurality of openings formed therein which define lines of weakness therein;
- and
- an electric current conductor adapted to be electrically connected in an alarm circuit attached to said rupturable member and positioned thereon whereby when said rupturable member ruptures along said lines of weakness as a result of fluid flow force or fluid pressure exerted thereon, said conductor is also ruptured;
- means for clamping said rupture disk, said annular spacer and said fluid flow indicator across said fluid flow passageway attached thereto and to said passageway;
- and
- an alarm circuit for providing an immediate indication when said electric current conductor is ruptured connected to said conductor.
