Self-sealing pressure vessel systems and methods
A compressed gas storage system that includes a pressure vessel. The pressure vessel includes a first vessel portion and a second vessel portion in fluid communication with the first vessel portion. The pressure vessel includes a third vessel portion in fluid communication with the second vessel portion. The compressed gas storage system includes a first valve positioned between the first vessel portion and the second vessel portion and a second valve positioned between the second vessel portion and the third vessel portion. The first valve allows and impedes fluid flow between the first and the second vessel portions. The second valve allows and impedes fluid flow between the second and the third vessel portions.
1. A compressed gas storage system, comprising:
a pressure vessel comprising:
a first vessel portion;
a second vessel portion in fluid communication with the first vessel portion;
a third vessel portion in fluid communication with the second vessel portion;
a first valve positioned between the first vessel portion and the second vessel portion; and
a second valve positioned between the second vessel portion and the third vessel portion,
wherein the first valve is configured to allow and impede fluid flow between the first and the second vessel portions,
wherein the second valve is configured to allow and impede fluid flow between the second and the third vessel portions, and
wherein when the pressure vessel has a rupture within the second vessel portion, the first valve impedes fluid flow from the second vessel portion to the first vessel portion and the second valve impedes fluid flow from the third vessel portion to the second vessel portion.
2. The compressed gas storage system of claim 1 , wherein the first vessel portion includes at least one hollow longitudinal section connecting with at least one hollow longitudinal section or at least one hollow bend of the second vessel portion.
3. The compressed gas storage system of claim 1 , further comprising:
an inlet in fluid communication with the first vessel portion, the inlet configured to receive compressed gas or fluid to fill the compressed gas storage system;
an outlet in fluid communication with the third vessel, the outlet configured to release compressed gas or fluid from the compressed gas storage system; and
an auxiliary fluid connection fluidly connecting the inlet and the outlet, the auxiliary fluid connection causing fluid flow between the first vessel portion and the third vessel portion when the rupture occurs in the second vessel portion.
4. The compressed gas storage system of claim 1 , wherein the first valve, the second valve, or both comprise:
a first opening;
a second opening; and
a flow impeder,
wherein the valve is configured to allow flow during a fill state, a discharge state, and a normal state, wherein the fill state is a state where fluids are being filled into the pressure vessel device, wherein the discharge state is a state where fluids are being discharged from the pressure vessel device, wherein the normal state is a state where fluids are contained within the pressure vessel portions and no filling, discharging, or leaking is occurring in the compressed gas storage system, and wherein during the fill and/or discharge state, the flow impeder is configured to prevent filling or discharging above a threshold rate of about 0 grams per second to about 25 grams per second so that a temperature of the pressure vessel device is not above or below a predetermined range of about −40 degrees Celsius to about 85 degrees Celsius.
5. The compressed gas storage system of claim 4 , wherein when the rupture causes a pressure or flow rate to exceed a fluid flow threshold in the second vessel portion, the flow impeder impedes flow from the second vessel portion to the first and/or the third vessel portion, and/or
when the rupture causes a pressure or a flow rate to exceed a fluid flow threshold in the second vessel portion, the flow impeder impedes flow from the first and/or the third vessel portion to the second vessel portion.
6. The compressed gas storage system of claim 4 , wherein the first opening is located between the first vessel portion and the flow impeder, and wherein the second opening is located between the second vessel portion and the flow impeder.
7. The compressed gas storage system of claim 1 , further comprising:
a resilient member coupling the flow impeder and an internal surface of the first vessel portion, the resilient member configured to allow movement of the flow impeder to block the first opening at or above a first flow rate as measured from the second vessel portion moving toward the first vessel portion, and the resilient member configured to allow movement of the flow impeder to block the second opening at or above a second flow rate as measured from the first vessel portion moving toward the second vessel portion.
8. The compressed gas storage system of claim 1 , wherein the second vessel portion comprises:
a first longitudinal section fluidly coupled to the first vessel portion;
a bend section having a first end and a second end and fluidly coupled to the first longitudinal section at the first end; and
a second longitudinal section fluidly coupled to the bend section at the second end and fluidly coupled to the third vessel portion.
9. The compressed gas storage system of claim 8 , wherein the first valve is located in the first longitudinal section,
wherein the first valve is located at least partially in the bend section, or
wherein the bend section defines a bend passage having a diameter that is narrower than a diameter of the first and second longitudinal sections.
