- the third hole 164 is opened. In other words, the safety valve 16 is in an open state. Therefore, the hydrogen gas that has flowed into the safety valve 16 from the third hole 164 is released to the outside via the second hole 163, the communication hole 166, and the release path 97.
- the supply source 4 When filling the gas tank 2 with hydrogen gas, the supply source 4 is connected to the joint 19 via the pipe 6. When hydrogen gas is supplied from the supply source 4, the hydrogen gas flows into the check valve 17 via the joint flow path 38, the first portion 33, the second portion 34, and the third portion 35 of the second flow path 13. .
- the check valve 17 is configured to allow hydrogen gas to flow from the third portion 35 to the filling portion 31, and therefore is in the open state. Specifically, the check valve body 102 moves to the first side due to the pressure of the hydrogen gas, thereby opening the check valve 17. As a result, the first flow path 12 communicates with the filled portion 31 of the first flow path 12 via the lateral hole 115 of the check valve housing 101 and the space S.
- hydrogen gas is filled into the gas tank 2 via the filling portion 31.
- hydrogen gas also flows into the check valve portion of the composite valve 15 via the second portion 34 to the fourth portion 36 of the second flow path 13 .
- the check valve portion is configured to restrict the flow of hydrogen gas from the fourth portion 36 to the delivery portion 32, it is in a closed state. As a result, hydrogen gas does not flow into the delivery portion 32 from the second flow path 13 .
- the consumer device 5 When sending hydrogen gas to the consumer device 5, the consumer device 5 is connected to the joint 19 via the pipe 7. Hydrogen gas in the gas tank 2 flows into the composite valve 15 via the delivery section 32 of the first flow path 12 .
- the check valve portion is configured to allow hydrogen gas to flow from the delivery portion 32 to the fourth portion 36, and is therefore in an open state. Thereby, hydrogen gas flows into the fourth portion 36, second portion 34, first portion 33, and joint flow path 38 of the second flow path 13, and is sent to the consumer device 5 via the pipe 7.
- hydrogen gas also flows into the check valve 17 from the second portion 34 of the second flow path 13 via the third portion 35 .
- the check valve 17 is closed due to the pressure of the hydrogen gas stored in the gas tank 2. As a result, hydrogen gas does not flow into the filling portion 31 from the third portion 35 .
- the second flow path 13 is used as a hydrogen gas filling path and a hydrogen gas supply path. In other words, part of the hydrogen gas filling route and part of the hydrogen gas supply route are shared.
- the third portion 35 intersects the second portion 34 at approximately 90 degrees with the first connection point P1 as a reference.
- the fourth portion 36 extends in parallel with the second portion 34 from the tip on the opposite side to the first connection point P1 with the second connection point P2 as a reference. Therefore, the path between the common port 37 and the fourth portion 36 (i.e., the solenoid valve portion of the composite valve 15) has only one bent portion, which prevents the shape of the second flow path 13 from becoming complicated. can. Further, when filling with hydrogen gas, moisture contained in the hydrogen gas may become water droplets and adhere to the inner surface of the second portion 34 .
- the flow path cross-sectional area of the filling portion 31 is larger than the flow path cross-sectional area of the delivery portion 32. Therefore, the flow rate when filling the gas tank 2 with hydrogen gas can be easily increased, and the gas tank 2 can be quickly filled with hydrogen gas.
- the second flow path 13, the integrated mounting hole 23, and the composite valve mounting hole 24 are arranged in the same plane. Thereby, the body 11 can be made more compact in the direction perpendicular to the plane.
- valve subassembly configured to regulate the flow of hydrogen gas from the fourth section 36 to the delivery section 32 and to permit the flow of hydrogen gas from the delivery section 32 to the fourth section 36; It further includes a compound valve 15 having a stop valve portion.
- the check valve section is arranged between the solenoid valve section and the fourth section 36 of the compound valve 15 .
- the filling portion 31 opens on the inner peripheral surface of the check valve mounting hole 92 of the integrated mounting hole 23, and the third portion 35 opens on the bottom surface of the check valve mounting hole 92.
- the check valve 17 is a check valve housing 101 configured to form a space S between the check valve mounting hole 92 and the inner circumferential surface of the check valve mounting hole 92, and is fixed within the check valve mounting hole 92.
- the check valve housing 101 includes a check valve housing 101 and a check valve body 102 slidably housed within the check valve housing 101.
- the check valve housing 101 has an accommodation hole 113 that accommodates the check valve body 102 and communicates with the third portion 35, and a horizontal hole 115 that communicates the accommodation hole 113 with the space S.
- the hydrogen gas that has flowed into the accommodation hole 113 from the third portion 35 flows into the filled portion 31 via the horizontal hole 115 and the space S. Therefore, compared to, for example, the case where the check valve body 102 slides within the check valve mounting hole 92, moisture contained in the hydrogen gas is less likely to adhere to the check valve body 102.
- the valve subassembly is a safety valve 16 having an inlet 165 configured to release hydrogen gas flowing into the inlet 165 to the outside when the temperature of the safety valve 16 exceeds a threshold temperature. 16 further included.
- the safety valve 16 is attached to the integrated attachment hole 23 together with the check valve 17 .
- the inlet 165 is configured to communicate with the filling portion 31 regardless of whether the check valve 17 is open or closed. According to the above configuration, the structure of the body 11 can be simplified compared to a case where a dedicated mounting hole for mounting the safety valve 16 is provided in the body 11. Further, in this embodiment, since the flow passage cross-sectional area of the filled portion 31 is large, hydrogen gas can be quickly released from the safety valve 16 in the event of an abnormality.
- the check valve housing 101 is fixed in the check valve mounting hole 92 by screw fastening, but is not limited to this, and may be fixed in the check valve mounting hole 92 by any fixing method such as press-fitting. It's okay.
- the check valve 17 may not include the check valve housing 101, and the check valve body 102 may be slidably accommodated in the check valve mounting hole 92.
- the second flow path 13, the integrated mounting hole 23, and the composite valve mounting hole 24 do not need to be arranged in the same plane.
- the safety valve 16 does not have to be arranged coaxially with the check valve 17.
- the check valve mounting hole 92 does not need to be provided coaxially with the safety valve mounting hole 91.
- the safety valve 16 may not be attached to the integrated attachment hole 23, but a dedicated attachment hole for attaching the safety valve 16 may be provided in the body 11. Also, the valve assembly 1 may not include the safety valve 16.
- the cross-sectional area of the flow path of the filling part 31 may be the same as the cross-sectional area of the flow path of the delivery part 32, or may be smaller than the cross-sectional area of the flow path of the delivery part 32.
- the check valve part of the composite valve 15 does not have to be arranged coaxially with the electromagnetic valve part.
- the valve assembly 1 may include a solenoid valve and a check valve independent of the solenoid valve. Further, the composite valve 15 may have only a solenoid valve portion and may not have a check valve portion.
- the angle ⁇ of the third portion 35 with respect to the second portion 34 may be 90° or less, such as 30°, 45°, or 60°.
- the fourth portion 36 does not need to be provided coaxially with the second portion 34 as long as it extends from the tip of the second portion 34 in parallel to the second portion 34 . That is, the axis of the fourth portion 36 does not have to coincide with the axis of the second portion 34.
- the overflow prevention valve 18 may be incorporated into the body 11 instead of being incorporated into the joint 19. Also, the valve assembly 1 may not include the overflow prevention valve 18. - Although the valve assembly 1 controls the flow of high-pressure hydrogen gas, the present invention is not limited to this, and may control the flow of gases other than hydrogen gas.
- the valve subassembly is a safety valve having an inlet, and is configured to discharge gas flowing into the inlet to the outside when the temperature of the safety valve exceeds a threshold temperature. Further, the safety valve may be attached to the first mounting hole together with the check valve, and the inlet may be configured to communicate with the filling portion regardless of whether the check valve is open or closed. .

Description
本明細書における「環状」は、全体として環状と見なせればよく、複数の部品又は部分を組み合わせて環状をなすものや、C字状のように一部に切り欠き等を有するものも含む。「環状」の形状には、軸方向視で、円形、楕円形、及び鋭い又は丸い角を持つ多角形が含まれるが、これらに限定されない。本明細書における「筒状」は、全体として筒状と見なせればよく、複数の部品又は部分を組み合わせて筒状をなすものや、C字状のように一部に切り欠き等を有するものも含む。「筒状」の形状には、軸方向視で、円形、楕円形、及び鋭い又は丸い角を持つ多角形が含まれるが、これらに限定されない。
図1に示す弁アセンブリ1は、例えば燃料電池自動車のガスタンク2に装着される。ガスタンク2には、例えば72.5MPa程度の高圧の水素ガスが貯蔵される。また、弁アセンブリ1は、複数の外部機器3のいずれか1つに選択的に接続される。複数の外部機器3は、ガスタンク2に充填する水素ガスの供給源4、及びガスタンク2から送出される水素ガスを消費する消費機器5を含む。供給源4は、例えば水素ステーションであり、配管6を介して弁アセンブリ1に接続される。消費機器5は、例えば自動車に搭載される燃料電池であり、配管7を介して弁アセンブリ1に接続される。弁アセンブリ1は、ガスタンク2に充填される水素ガス及びガスタンク2から送出される水素ガスの流通を制御する。
ボディ11は、例えば金属材料製である。ボディ11は、例えばその一部が張り出した直方体状をなしている。本実施形態のボディ11は、切れ目のない連続した一体品(one piece)である。ボディ11の外面は、第1側面11aと、第2側面11bと、第3側面11cと、第4側面11dとを含む。第1側面11aと第3側面11cとは、例えば互いに平行である。第2側面11bと第4側面11dとは、例えば互いに平行である。第1側面11a及び第3側面11cは、例えば第2側面11b及び第4側面11dに対して直交する。
手動弁14は、手動弁ハウジング41と、手動弁体42とを備えている。手動弁ハウジング41は、例えば筒状をなしている。本実施形態において、手動弁ハウジング41は、軸方向視で、円形の形状を有している。手動弁ハウジング41は、例えばネジ締結又は圧入等の任意の固定方法により手動弁用取付穴22に固定されている。手動弁体42は、例えば円柱状をなしている。手動弁体42は、例えばネジ締結により、手動弁ハウジング41内に第2流路13の第2部分34に沿って移動可能かつ手動弁ハウジング41内における位置を保持可能に収容されている。
図2に示すように、複合弁15は、スリーブ51と、プラグ52と、ソレノイドアクチュエータ53と、電磁弁体54と、逆止弁体55と、逆止弁用付勢部材56とを備えている。また、複合弁15は、カバー57をさらに備えてもよい。
ソレノイドコイル81は、例えば筒状をなしている。本実施形態において、ソレノイドコイル81は、軸方向視で、円形の形状を有している。ソレノイドコイル81は、小径部61の外周に固定されている。固定鉄心82は、磁性材料製である。固定鉄心82は、スリーブ51内に固定されている。可動鉄心83は、磁性材料製である。可動鉄心83は、例えば円柱状をなしている。可動鉄心83は、スリーブ51内において軸方向にスライド可能である。可動鉄心83は、電磁弁体54と一体で軸方向にスライド可能となるように、電磁弁体54に連結されている。電磁弁体54は、例えば樹脂材料製であるが、金属材料であってもよい。
図3に示すように、統合取付穴23は、安全弁16が取り付けられる安全弁用取付穴91と、逆止弁17が取り付けられる逆止弁用取付穴92とを有している。安全弁用取付穴91は、ボディ11の外面である第3側面11cに開口している。逆止弁用取付穴92は、安全弁用取付穴91の底面に開口している。つまり、逆止弁用取付穴92は、安全弁用取付穴91に対して直線的に並ぶように、安全弁用取付穴91の奥側に設けられている。以下の説明では、統合取付穴23(安全弁用取付穴91)における開口端側を第1側といい、その反対側、すなわち、統合取付穴23(逆止弁用取付穴92)における底面側を第2側という。
逆止弁17は、逆止弁ハウジング101と、逆止弁体102とを備えている。また、逆止弁17は、弁座103と、逆止弁付勢部材104とをさらに備えてもよい。
安全弁16は、安全弁ハウジング141と、安全弁体142と、栓体143とを備えている。また、安全弁16は、安全弁付勢部材144と、留め具145とをさらに備えてもよい。
ガスタンク2に水素ガスを充填する際には、継手19に配管6を介して供給源4が接続される。供給源4から水素ガスが供給されると、水素ガスは継手流路38、第2流路13の第1部分33、第2部分34及び第3部分35を介して逆止弁17に流入する。上記のように逆止弁17は、第3部分35から充填部分31への水素ガスの流通を許容するように構成されているため、開状態となる。詳しくは、水素ガスの圧力により逆止弁体102が第1側に移動することで、逆止弁17が開状態となる。その結果、第1流路12が逆止弁ハウジング101の横孔115及び空間Sを介して第1流路12の充填部分31と連通する。これにより、充填部分31を介して水素ガスがガスタンク2に充填される。このとき、水素ガスは、第2流路13の第2部分34から第4部分36を介して複合弁15の逆止弁部分にも流入する。しかし、逆止弁部分は、第4部分36から送出部分32への水素ガスの流通を規制するように構成されているため、閉状態となる。これにより、第2流路13から送出部分32には水素ガスは流入しない。
(1)第3部分35は、第1接続箇所P1を基準として第2部分34に対して略90°で交差する。第4部分36は、第2接続箇所P2を基準として第1接続箇所P1とは反対側の先端部から第2部分34と平行に延びている。したがって、共通ポート37と第4部分36(すなわち複合弁15の電磁弁部分)との間の経路における屈曲部分が1箇所のみとなるため、第2流路13の形状が複雑化することを抑制できる。また、水素ガスの充填時において、水素ガスに含まれる水分が水滴となって第2部分34の内面に付着することがある。こうした水滴は、通常、第2部分34の延伸方向に沿って直線的に移動するため、第2部分34から平行に延びる第4部分36に溜まりやすくなる。特に、第3部分35が第2部分34に対して略90°で交差するため、上記水滴は、第3部分35が90°よりも大きな角度(鈍角)で第2部分34に交差する場合に比べ、第3部分35に流れ込みにくい。これにより、逆止弁17に水滴が付着することを抑制できる。
・逆止弁ハウジング101は、ネジ締結により逆止弁用取付穴92内に固定されたが、これに限らず、例えば圧入等の任意の固定方法により逆止弁用取付穴92内に固定されてもよい。
・第2流路13、統合取付穴23及び複合弁用取付穴24が、同一平面内に配置されていなくてもよい。
・安全弁16を統合取付穴23に取り付けず、安全弁16を取り付けるための専用の取付穴をボディ11に設けてもよい。また、弁アセンブリ1は、安全弁16を備えなくてもよい。
・複合弁15の逆止弁部分は、電磁弁部分と同軸上に配置されていなくてもよい。
第4部分36は、第2部分34における先端部から第2部分34と平行に延びていれば、第2部分34と同軸上に設けられていなくてもよい。つまり、第4部分36の軸線は第2部分34の軸線と一致しなくてもよい。
・弁アセンブリ1は高圧の水素ガスの流通を制御したが、これに限らず、水素ガス以外のガスの流通を制御してもよい。
(付記1)前記弁サブアセンブリは、流入口を有する安全弁であって、前記安全弁の温度が閾値温度を超えた場合に前記流入口に流入するガスを外部に放出するように構成される安全弁をさらに含み、前記安全弁は、前記第1取付穴に前記逆止弁とともに取り付けられ、前記流入口は、前記逆止弁の開閉状態に関わらず、前記充填部分と連通するように構成されてもよい。
