Description
本発明は、示温材が貼付されたガスボンベに関する。 The present invention relates to a gas cylinder to which a temperature indicating material is attached.
一般的に、プロパンガスやフロンガス等のガスボンベには、保管温度が異常に高くなった場合に、内部の高圧ガスを逃がして爆発を防ぐための安全装置として可溶栓が取り付けられている（例えば下記の特許文献１）。 Generally, gas cylinders such as propane gas and fluorocarbon gas are equipped with fusible plugs as a safety device to prevent explosions by releasing the high-pressure gas inside if the storage temperature becomes abnormally high (for example, Patent Document 1 below.
可溶栓は、一般的に６０℃程度の外気温で溶解し、高圧となったガスボンベ内部のガスを噴出させる構造になっているが、この溶解温度に満たない４０℃程度の外気温でも可溶栓が劣化し、ガスボンベの内圧に起因して徐々にガスが漏洩するケースが存在する。昨今においては、これまで涼しかった地域においても夏季の気温が４０℃を超える状況になっており、ガスボンベを適正温度以下に保つことが難しくなっている。しかしながら、ガスボンベ及び可溶栓が過去にどのような環境下に保管されていたのかの温度履歴を示すものはなく、可溶栓の劣化具合を図る指標もなかった。そのため、過去に適正温度以上で保管されたことで劣化した可溶栓が取り付けられたガスボンベが流通しており、ガスの漏洩事故が起こっていた。 Fusible plugs are generally designed to melt at an outside temperature of around 60°C and blow out the high-pressure gas inside the gas cylinder, but they can also be used at outside temperatures of around 40°C, which is below this melting temperature. There are cases where the fuser plug deteriorates and gas gradually leaks due to the internal pressure of the gas cylinder. In recent years, summer temperatures have exceeded 40°C even in areas that used to be cool, making it difficult to keep gas cylinders at or below the appropriate temperature. However, there is nothing that shows the temperature history of the environment in which gas cylinders and fusible plugs have been stored in the past, and there is no index to measure the degree of deterioration of fusible plugs. As a result, gas cylinders with fusible plugs that have deteriorated due to storage above the appropriate temperature are in circulation, leading to gas leaks.
したがって、ガスボンベが過去にどのような温度環境下で保管されていたかを把握して、可溶栓の劣化具合を推定可能にすることが求められている。 Therefore, it is required to be able to estimate the degree of deterioration of the fusible plug by understanding the temperature environment in which the gas cylinder was stored in the past.
本発明は、上記課題を解決するために発明されたものであり、過去にどのような温度環境下で保管されていたかを把握することのできるガスボンベを提供することを目的とする。 The present invention was invented in order to solve the above problems, and an object of the present invention is to provide a gas cylinder in which it is possible to know in what temperature environment it was stored in the past.
上記目的を達成する本発明に係るガスボンベは、可溶栓を有し、不可逆的に変色する示温材が、少なくとも前記可溶栓に貼付されたガスボンベである。
A gas cylinder according to the present invention that achieves the above object is a gas cylinder that has a fusible stopper, and a temperature indicating material that irreversibly changes color is attached to at least the fusible stopper .
上述のガスボンベによれば、ガスボンベの保管環境が所定の温度（例えば４０℃）以上になった場合、示温材が変色して、所定の温度を下回っても変色した状態を維持するために、過去にどのような温度環境下に保管されていたかを把握することができる。また、これによって可溶栓の劣化具合を推定可能にすることで、劣化具合に応じて保管場所や方法の変更や可溶栓の交換を行うことができ、ガスの漏洩を防ぐことができる。 According to the above-mentioned gas cylinder, when the storage environment of the gas cylinder reaches a predetermined temperature (for example, 40°C) or higher, the temperature indicating material changes color, and in order to maintain the discolored state even if the temperature drops below the predetermined temperature, the past It is possible to determine the temperature and environment in which the product was stored. Furthermore, by making it possible to estimate the degree of deterioration of the fusible plug, it is possible to change the storage location or method or replace the fusible plug depending on the degree of deterioration, thereby preventing gas leakage.

本実施形態に係るガスボンベ１は、図１～図４に示すように、ガスが保管される本体部１０と、本体部１０の上方に取り付け可能に配置されるキャップ２０と、キャップ２０の内部に設けられる二口バルブ３０と、本体部１０に貼付された第１示温材（示温材に相当）４０と、二口バルブ３０の取付部９０に取り付けられる可溶栓５０と、可溶栓５０に貼付された第２示温材（示温材に相当）６０と、を有する。 As shown in FIGS. 1 to 4, the gas cylinder 1 according to the present embodiment includes a main body 10 in which gas is stored, a cap 20 that is attachably disposed above the main body 10, and a cap 20 inside the cap 20. The two-port valve 30 provided, the first temperature indicating material (equivalent to a temperature indicating material) 40 affixed to the main body 10, the fusible plug 50 attached to the mounting portion 90 of the two-port valve 30, and the fusible plug 50. It has a second temperature indicating material (corresponding to a temperature indicating material) 60 attached thereto.
二口バルブ３０は、液側バルブ３１と、気体側バルブ３２と、を有する。ガスを高圧状態で液化して回収するときには、液側バルブ３１によって回収する。またガスを気体のまま回収するときには、気体側バルブ３２によって回収する。なお、本実施形態に係るガスボンベ１は、二口バルブ３０である必要はなく液側バルブ３１のみを備えたものであってもよい。 The two-port valve 30 has a liquid side valve 31 and a gas side valve 32. When the gas is liquefied under high pressure and recovered, the liquid side valve 31 is used to recover the gas. Further, when the gas is recovered as a gas, it is recovered by the gas side valve 32. Note that the gas cylinder 1 according to the present embodiment does not need to have the two-port valve 30 and may include only the liquid side valve 31.
第１示温材４０は、図１に示すように、本体部１０に貼付される。第１示温材４０が本体部１０に貼付される場所は特に限定されないが、人の目線の高さに近い場所に貼付されることが好ましい。 The first temperature indicating material 40 is attached to the main body part 10, as shown in FIG. The location where the first temperature indicating material 40 is attached to the main body portion 10 is not particularly limited, but it is preferably attached at a location close to the eye level of the person.
第１示温材４０としては公知のものを用いることができ、例えば、サーモラベル（登録商標）（商品名：日油技研工業社製）や加熱積算ラベル（商品名：日油技研工業社製）を用いることができる。第１示温材４０の最下面の粘着剤層が本体部１０に貼付される。 As the first temperature indicating material 40, publicly known materials can be used, such as Thermo Label (registered trademark) (trade name: manufactured by Nihon Yu Giken Kogyo Co., Ltd.) and heating cumulative label (trade name: manufactured by Nihon Yu Giken Kogyo Co., Ltd.). can be used. The adhesive layer on the lowermost surface of the first temperature indicating material 40 is attached to the main body part 10.
本実施形態において、第１示温材４０は、本体部１０に３枚貼付される。本実施形態において、３枚の第１示温材４０は、それぞれ４０℃、５０℃、および６０℃が変色温度となっている。 In this embodiment, three first temperature indicating materials 40 are attached to the main body portion 10 . In this embodiment, the three first temperature indicating materials 40 have discoloration temperatures of 40°C, 50°C, and 60°C, respectively.
第１示温材４０は、所定の温度環境下によって変色するものが用いられるが、より好ましくは、所定の温度環境下に配置される時間に応じて、色の濃度が変化することが好ましい。例えば、第１示温材４０が黒色に変色する場合、所定の温度環境下に配置される時間に応じて、白、グレー、黒の順に徐々に濃度が変化する。このような第１示温材４０によれば、色の濃度によってどの程度の時間、所定の温度環境下に配置されていたかを把握することができる。 The first temperature indicating material 40 is one that changes color depending on a predetermined temperature environment, and more preferably, the color density changes depending on the time it is placed in a predetermined temperature environment. For example, when the first temperature indicating material 40 changes color to black, the density gradually changes in the order of white, gray, and black depending on the time it is placed in a predetermined temperature environment. According to the first temperature indicating material 40, it is possible to determine how long the first temperature indicating material 40 has been placed in a predetermined temperature environment based on the color density.
可溶栓５０は、図２に示すように、二口バルブ３０の外表面に設けられる取付部９０に取り付けられる。可溶栓５０は、図３に示すように、外周に雄ネジ５１ａが形成される外周部材５１と、外周部材５１の内周に配置される内周部材５２と、を有する。 The fusible plug 50 is attached to a mounting portion 90 provided on the outer surface of the two-port valve 30, as shown in FIG. As shown in FIG. 3, the fusible plug 50 includes an outer circumferential member 51 having a male thread 51a formed on its outer circumference, and an inner circumferential member 52 disposed on the inner circumference of the outer circumferential member 51.
外周部材５１は、例えば、青銅、黄銅、または砲金などによって形成される。また、内周部材５２は、例えば、融点の低い鉛やスズによって形成される。 The outer peripheral member 51 is made of, for example, bronze, brass, gunmetal, or the like. Further, the inner circumferential member 52 is formed of, for example, lead or tin, which has a low melting point.
このように構成された可溶栓５０において、ガスボンベ１の保管温度が６０℃以上になったときに、融点の低い内周部材５２が溶解して穴が開くことで、本体部１０内のガスを逃がして爆発を防ぐことができる。したがって、ガスボンベ１を保管する際は、保管温度が６０℃を超えないように調整する必要があるが、可溶栓５０は４０℃程度で劣化し本体部１０内のガスが漏れる恐れがあるため、保管温度は４０℃を超えないよう調整することが好ましい。 In the fusible stopper 50 configured in this way, when the storage temperature of the gas cylinder 1 reaches 60° C. or higher, the inner circumferential member 52 having a low melting point melts and a hole is formed, so that the gas inside the main body 10 is can be released to prevent an explosion. Therefore, when storing the gas cylinder 1, it is necessary to adjust the storage temperature so that it does not exceed 60°C, but the fusible plug 50 deteriorates at about 40°C and there is a risk of gas inside the main body 10 leaking. Preferably, the storage temperature is adjusted so as not to exceed 40°C.
第２示温材６０は、第１示温材４０と同一のものを用いることができる。第２示温材６０は、図２、図４に示すように、可溶栓５０に３枚貼付される。第２示温材６０は、可溶栓５０の外周部材５１の頭部に貼付される。なお、第２示温材６０が可溶栓５０に貼付される場所は特に限定されず、図４（Ａ）に示すように可溶栓５０の正面でも良く、図４（Ｂ）に示すように側面でも良い。３つの第２示温材６０は、それぞれ４０℃、５０℃、および６０℃が変色温度となっている。 The second temperature indicating material 60 can be the same as the first temperature indicating material 40. As shown in FIGS. 2 and 4, three second temperature indicating materials 60 are attached to the fusible plug 50. The second temperature indicating material 60 is attached to the head of the outer peripheral member 51 of the fusible plug 50. Note that the location where the second temperature indicating material 60 is attached to the fusible plug 50 is not particularly limited, and may be on the front of the fusible plug 50 as shown in FIG. 4(A), or as shown in FIG. 4(B). It can also be on the side. The three second temperature indicating materials 60 have discoloration temperatures of 40°C, 50°C, and 60°C, respectively.
また、第２示温材６０は、第１示温材４０と同様に、所定の温度環境下に配置される時間に応じて、色の濃度が変化することが好ましい。このような第２示温材６０によれば、色の濃度によってどの程度の時間、所定の温度環境下に配置されていたかを把握することができる。 Further, like the first temperature indicating material 40, it is preferable that the color density of the second temperature indicating material 60 changes depending on the time it is placed in a predetermined temperature environment. According to the second temperature indicating material 60, it is possible to determine how long the second temperature indicating material 60 has been placed in a predetermined temperature environment based on the color density.
上記のように構成されたガスボンベ１が、５０℃以上６０℃未満の環境下に配置された場合、図５に示すように、４０℃および５０℃の変色温度を備える第１示温材４０および第２示温材６０は変色する。一旦変色した第１示温材４０および第２示温材６０は、４０℃以下の温度になったとしても、不可逆であるため、変色状態が維持される。したがって、ガスボンベ１が過去にどのような温度環境下で保管されていたかを可視化して把握することができる。 When the gas cylinder 1 configured as described above is placed in an environment of 50°C or higher and lower than 60°C, as shown in FIG. 2. The temperature indicating material 60 changes color. Even if the temperature of the first temperature indicating material 40 and the second temperature indicating material 60, which have once changed color, reaches a temperature of 40° C. or lower, the discolored state is maintained because it is irreversible. Therefore, it is possible to visualize and understand under what temperature environment the gas cylinder 1 was stored in the past.
また、第１示温材４０および第２示温材６０を用いて可視化できるため、４０℃の温度環境になる前に、温度環境を冷房等によってコントロールしたり、ガスボンベ１をより低温の場所へ移動させたりすることができる。 In addition, since it can be visualized using the first temperature indicator 40 and the second temperature indicator 60, the temperature environment can be controlled by air conditioning or the like, or the gas cylinder 1 can be moved to a lower temperature place before the temperature reaches 40°C. You can
以上説明したように、本実施形態に係るガスボンベ１は、不可逆的に変色する第１示温材４０および第２示温材６０が貼付されたガスボンベ１である。このように構成されたガスボンベ１によれば、保管場所が所定の温度（例えば４０℃）以上になった場合、第１示温材４０および第２示温材６０が変色して、変色した状態を維持するために、過去にどのような温度環境下で保管されていたかを把握することができる。また、これによって可溶栓の劣化具合を推定可能にすることで、劣化具合に応じて保管場所や方法の変更や可溶栓の交換を行うことができ、ガスの漏洩を防ぐことができる。 As explained above, the gas cylinder 1 according to the present embodiment is the gas cylinder 1 to which the first temperature indicating material 40 and the second temperature indicating material 60 which irreversibly change color are attached. According to the gas cylinder 1 configured in this way, when the storage location reaches a predetermined temperature (for example, 40° C.) or higher, the first temperature indicating material 40 and the second temperature indicating material 60 change color and maintain the discolored state. Therefore, it is possible to understand the temperature environment in which the item was stored in the past. Furthermore, by making it possible to estimate the degree of deterioration of the fusible plug, it is possible to change the storage location or method or replace the fusible plug depending on the degree of deterioration, thereby preventing gas leakage.
また、ガスボンベ１は、可溶栓５０を有し、可溶栓５０に第２示温材６０が貼付される。このように構成されたガスボンベ１によれば、第２示温材６０によって可溶栓５０の温度履歴を把握することができる。よって可溶栓５０の状態をより正確に推定することができる。 Further, the gas cylinder 1 has a fusible plug 50, and a second temperature indicating material 60 is attached to the fusible plug 50. According to the gas cylinder 1 configured in this manner, the temperature history of the fusible plug 50 can be ascertained by the second temperature indicating material 60. Therefore, the state of the fusible plug 50 can be estimated more accurately.
また、第１示温材４０および第２示温材６０は、所定の温度環境下に配置される時間に応じて、色の濃度が変化する。このように構成されたガスボンベ１によれば、色の濃度によってどの程度の時間、所定の温度環境下に配置されていたかを把握することができる。 Further, the color density of the first temperature indicating material 40 and the second temperature indicating material 60 changes depending on the time they are placed in a predetermined temperature environment. According to the gas cylinder 1 configured in this way, it is possible to grasp how long the gas cylinder has been placed in a predetermined temperature environment based on the color density.
