Abstract
A burst disc system can include a plurality of burst discs serially arranged to successively rupture one at a time. Each burst disc can be configured to rupture at one or more set burst pressures. The system can include an indicator configured to allow a user to receive an indication that a last burst disc of the plurality of burst discs has ruptured.
Claims17
A burst disc system, comprising:
- a plurality of burst discs serially arranged to successively rupture one at a time, each burst disc configured to rupture at one or more set burst pressures, wherein one or more burst discs of the plurality of burst discs has a different burst pressure than one or more of the other of the plurality of burst discs, wherein the plurality of burst discs comprise a first burst disc, a second burst disc, a third burst disc, and a fourth burst disc, wherein the first burst disc includes a lower burst pressure than one or more downstream burst discs, wherein the first burst disc and the second burst disc have a first burst pressure, and wherein the third burst disc and the fourth burst disc have a second burst pressure higher than the first;
- and
- an indicator configured to allow a user to receive an indication that a last burst disc of the plurality of burst discs has ruptured.
An engine system, comprising:
- a main flow line;
- and
- a branch in fluid communication with the main flow line, the branch comprising:
- a burst disc system, comprising:
- a plurality of burst discs serially arranged to successively rupture one at a time, each burst disc configured to rupture at one or more set burst pressures, wherein one or more burst discs of the plurality of burst discs has a different burst pressure than one or more of the other of the plurality of burst discs, wherein the plurality of burst discs comprise a first burst disc, a second burst disc, a third burst disc, and a fourth burst disc, wherein the first burst disc includes a lower burst pressure than one or more downstream burst discs, wherein the first burst disc and the second burst disc have a first burst pressure, and wherein the third burst disc and the fourth burst disc have a second burst pressure higher than the first;
- and
- an indicator configured to allow a user to receive an indication that a last burst disc of the plurality of burst discs has ruptured.
4 more elements
A method, comprising:
- forming a burst disc system having a plurality of burst discs for detecting pressure pulses in a flow system, each burst disc configured to burst successively with a successive pressure wave such that each burst disc bursts one at a time to provide a passive counter, wherein the number of the plurality of burst discs in the burst disc system is selected to match a pressure pulse failure amount for a different system part, wherein one or more burst discs of the plurality of burst discs has a different burst pressure than one or more of the other of the plurality of burst discs, wherein the plurality of burst discs comprise a first burst disc, a second burst disc, a third burst disc, and a fourth burst disc, wherein the first burst disc includes a lower burst pressure than one or more downstream burst discs, wherein the first burst disc and the second burst disc have a first burst pressure, and wherein the third burst disc and the fourth burst disc have a second burst pressure higher than the first.
