Description
圧力容器は、例えば、水素、酸素、天然ガス、窒素、プロパン、メタン、及び他の燃料のような種々の流体を圧力下で格納するために一般に使用される。一般的に、圧力容器は、任意のサイズ又は構成であり得る。容器は、例えば、重い又は軽い、1回使用(例えば、使い捨て)である、再使用可能である、高い圧力(例えば、50psiより大きい)又は低い圧力(例えば、50psiより小さい)を受ける、或は、高温又は低温で流体を貯蔵するために使用される可能性がある。
一態様において、内部環境を有する圧力容器が開示され、圧力容器は、シェル、ライナー、及びボスを含む。ライナーは、シェル内に位置決めされ、内部環境を画定する。ボスは、シェルとライナーとの間の第1の境界に位置する。ボスは、空洞、及び、空洞内に位置する放出構造を含む。空洞は、ライナーとボスとの間の第2の境界に位置し、空洞は、内部環境と連通するボスの内部表面に位置する。ガス放出経路は、第1の境界から放出構造を通り、圧力容器の内部環境に入るように画定される。
1. 内部環境を有する圧力容器であって、
シェルと、
前記シェル内に位置決めされ、前記内部環境を画定するライナーと、
前記シェルと前記ライナーとの間の第1の境界に位置するボスとを含み、前記ボスは、
前記ライナーと前記ボスとの間の第2の境界にある空洞であって、前記内部環境と連通する前記ボスの内部表面に位置する空洞、及び、
前記空洞内に位置する放出構造を含み、ガス放出経路は、前記第1の境界から、前記放出構造を通り、前記圧力容器の前記内部環境に入るように画定される、圧力容器。
3. 前記放出構造は、前記ライナーの材料が前記放出構造に入るのを抑制しながら、ガスが前記放出構造を通過することを可能にする多孔性を有する、条項1又は2に記載の圧力容器。
5. 前記空洞は、前記放出構造の前記環状形状に対応する補足的な環状形状を含む、条項4に記載の圧力容器。
7. 前記空洞は、空洞のセットのうちの1つであり、前記空洞のセットにおける各空洞は、前記放出構造のセットにおける前記放出構造の1つの形状に対応するように構成される、条項6に記載の圧力容器。
9. 圧力容器用のボスであって、
前記圧力容器の外部環境と前記圧力容器の内部環境との間の流体連通を可能にするように構成されるポートと、
前記ポートから半径方向に外側に延在し、外部側及び内部側を含むフランジと、
前記フランジの前記内部側に位置する空洞と、
前記空洞内に位置するガス放出構造とを含む、ボス。
11. 前記ガス放出構造は、溶融ポリマー材料が前記ガス放出構造に入るのを抑制しながら、ガスが前記ガス放出構造を通過することを可能にする多孔性を有する、条項9〜10のいずれか1項に記載のボス。
13. 前記空洞は、前記ガス放出構造の前記環状形状に対応する補足的な環状形状を含む、条項12に記載のボス。
15. 前記空洞は、空洞のセットのうちの1つのであり、前記空洞のセットにおける各空洞は、前記放出構造のセットにおける前記放出構造の1つの形状に対応するように構成される、条項14に記載のボス。
17. 圧力容器内で使用するためのボスを製造する方法であって、
金属部品を焼結することで、前記金属部品が、ガスが焼結された前記金属部品を通過することを可能にするが、溶融ポリマー材料が焼結された前記金属部品に入るのを制限する多孔性を有するようにすること、及び、
焼結された前記金属部品を、前記ボスの対応する空洞に挿入することを含む、方法。
19. 前記ボスは、前記ボスの外部側と前記ボスの内部側を接続するポートを含み、前記機械加工は、前記ボスの前記内部側の表面を機械加工することを含む、条項18に記載の方法。
20. 前記ボスは、前記ポートから半径方向に外側に延在し、外部側及び内部側を含むフランジを含み、前記機械加工は、前記フランジの前記内部側の表面を機械加工することを含む、条項19に記載の方法。
本開示は、圧力容器において使用するための、例示的な放出構造、及び、こうした放出構造を生成するための方法を述べる。ガス放出構造は、圧力容器のボス内に組み込まれ得、例示的な構造は、圧力下で、ボスからライナーの分離及び/又はシェルからライナーの分離を防止する。ガス放出構造は、ライナーとライナーに繋がるシェルの内部表面との間に捕捉されたガス等といった、ライナーとシェル(又はボス)との間に捕捉されたガスの放出を可能にする。本開示は、一態様において、例示的なガス放出構造のうちの少なくとも1つを、圧力容器10のボス16と組合せることに関する。幾つかの実施形態において、放出構造は、ボスの対応する空洞内に位置決めされる差し込み物又は挿入物として構成される。例示的なガス放出構造のそれぞれは、ライナー20とシェル18(又はボス16)との間に蓄積するガスが、圧力容器10の内部環境17に放出されることを可能にする特徴を有する。ボス16のポート(ポート26等)が開口している場合、圧力容器10の内部環境17からのガスは、圧力容器10の外部の外部環境19に放出され得る。例えば、図4A及び5に示すように、第1の例示的な放出構造28aは、シェル18とライナー20との間の境界60から圧力容器10の内部の環境17へと、ガスを放出することができる経路54を提供する。
