［実施形態］
〔液化ガスタンクの構成〕
まず、本発明の一実施形態に係る液化ガスタンクの構成を図面に基づいて説明する。
図１および図２に示す液化ガスタンク１は、外部の設備から供給される液化ガスＧを一時的に貯蔵して、各種製造装置や処理装置あるいは工場などに排出する。液化ガスタンク１は、タンク本体２と、供給部３と、排出部４と、水切り部５とを備えている。 [Embodiment]
[Structure of liquefied gas tank]
First, a configuration of a liquefied gas tank according to an embodiment of the present invention will be described with reference to the drawings.
The liquefied gas tank 1 shown in FIGS. 1 and 2 temporarily stores a liquefied gas G supplied from an external facility and discharges the liquefied gas G to various manufacturing apparatuses, processing apparatuses or factories. The liquefied gas tank 1 includes a tank body 2, a supply unit 3, a discharge unit 4, and a drain unit 5.

タンク本体２は、液化ガスＧを貯蔵する。タンク本体２は、その外観が略円柱状となるように形成され、縦長になるように設置されている。タンク本体２に貯蔵される液化ガスＧとしては、液化水素、液化酸素、液化窒素、液化ヘリウム、液化アルゴン、液化天然ガス（ＬＮＧ）などの低温の液化ガスが例示できる。   The tank body 2 stores the liquefied gas G. The tank main body 2 is formed so as to have a substantially columnar appearance, and is installed so as to be vertically long. Examples of the liquefied gas G stored in the tank body 2 include low-temperature liquefied gas such as liquefied hydrogen, liquefied oxygen, liquefied nitrogen, liquefied helium, liquefied argon, and liquefied natural gas (LNG).

供給部３は、タンク本体２の下面２１に接続され、タンク本体２内に液化ガスＧを供給する供給配管３１と、当該供給配管３１に設けられた供給バルブ３２とを備えている。
排出部４は、下面２１に接続され、タンク本体２内から液化ガスＧを排出する排出配管４１と、当該排出配管４１に設けられた排出バルブ４２とを備えている。
なお、供給配管３１および排出配管４１は、本発明の配管に該当する。 The supply unit 3 is connected to the lower surface 21 of the tank main body 2, and includes a supply pipe 31 that supplies the liquefied gas G into the tank main body 2, and a supply valve 32 provided in the supply pipe 31.
The discharge unit 4 includes a discharge pipe 41 connected to the lower surface 21 for discharging the liquefied gas G from the inside of the tank body 2, and a discharge valve 42 provided in the discharge pipe 41.
The supply pipe 31 and the discharge pipe 41 correspond to the pipe of the present invention.

水切り部５は、タンク本体２とは別体のＳＵＳ板により構成されている。水切り部５は、タンク本体２の側面２２の全周にわたって設けられ、下方に延びるように両面粘着テープ６１によって側面２２に固定されている。つまり、水切り部５は、タンク本体２における供給配管３１との接続部分２１Ａ、および、排出配管４１との接続部分２１Ｂの両方を囲む位置から、下方に延びるように設けられており、タンク本体２の外周面を伝って流れる水Ｗ（雪解け水や雨水）が各配管３１，４１に到達することを防止する。
水切り部５の上端５１には、タンク本体２の側面２２を伝って流れる水Ｗが水切り部５と側面２２との間に浸入することを抑制する浸入抑制部材６２が設けられている。浸入抑制部材６２は、例えば樹脂製のコーキング材を塗布することによって設けられている。
水切り部５の下端５２には、当該下端５２を覆う例えば樹脂製の被覆部材６３が設けられている。 The drainer 5 is formed of a SUS plate separate from the tank body 2. The drainer 5 is provided over the entire circumference of the side surface 22 of the tank body 2 and is fixed to the side surface 22 by a double-sided adhesive tape 61 so as to extend downward. That is, the draining portion 5 is provided so as to extend downward from a position surrounding both the connecting portion 21A with the supply pipe 31 and the connecting portion 21B with the discharge pipe 41 in the tank body 2. To prevent the water W (snow melt water or rainwater) flowing along the outer peripheral surface from reaching the respective pipes 31 and 41.
At the upper end 51 of the drainer 5, there is provided an infiltration suppressing member 62 which suppresses water W flowing along the side surface 22 of the tank body 2 from entering between the drainer 5 and the side surface 22. The infiltration suppressing member 62 is provided by applying a resin caulk material, for example.
A lower end 52 of the drainer 5 is provided with a covering member 63 made of, for example, resin and covering the lower end 52.

〔液化ガスタンクの作用〕
次に、液化ガスタンク１の作用を説明する。
タンク本体２の上面２３や側面２２に付着した水Ｗは、側面２２を伝って下方に流れる。水切り部５が設けられていない場合、水Ｗは、図１および図２に二点鎖線で示すように、各配管３１，４１や各バルブ３２，４２に到達する。各配管３１，４１や各バルブ３２，４２は液化ガスＧによって冷やされているため、これらに付着した水Ｗは凍結してしまう。その後、さらに水Ｗが下方に流れてくると、凍結部分が増えて、やがて、下面２１や各配管３１，４１や各バルブ３２，４２を覆う氷塊Ｆが形成される。
このような氷塊Ｆが形成されてしまうと、下面２１や各配管３１，４１や各バルブ３２，４２からの液漏れやガス漏れなどの不具合を目視で点検することが困難になってしまう。 [Function of liquefied gas tank]
Next, the operation of the liquefied gas tank 1 will be described.
The water W attached to the upper surface 23 and the side surface 22 of the tank body 2 flows downward along the side surface 22. When the draining section 5 is not provided, the water W reaches each of the pipes 31, 41 and each of the valves 32, 42 as shown by a two-dot chain line in FIGS. Since the pipes 31 and 41 and the valves 32 and 42 are cooled by the liquefied gas G, the water W attached to them is frozen. Thereafter, when the water W further flows downward, the frozen portion increases, and eventually, an ice block F covering the lower surface 21, the pipes 31, 41, and the valves 32, 42 is formed.
If such ice blocks F are formed, it will be difficult to visually inspect defects such as liquid leakage and gas leakage from the lower surface 21, the pipes 31, 41, and the valves 32, 42.

これに対し、本実施形態の液化ガスタンク１には水切り部５が設けられている。このため、水Ｗは、図１および図２に実線で示すように、浸入抑制部材６２、水切り部５の外周面を伝って、水切り部５の下端５２から下方に落下し、各配管３１，４１や各バルブ３２，４２に到達しない。したがって、各配管３１，４１や各バルブ３２，４２の凍結や氷塊Ｆの発生が抑制され、これらからの液漏れやガス漏れなどの不具合を目視で点検することが容易になる。
特に液化ガスタンク１が寒冷地帯や積雪地帯に設置されている場合、各配管３１，４１や各バルブ３２，４２は、液化ガスＧに加えて外気温によっても冷やされるため凍結しやすくなるが、水切り部５を設けることによって、凍結や氷塊Ｆの発生を抑制できる。
また、タンク本体２と別体の水切り部５を側面２２に固定しているため、下面２１や上面２３に固定する場合と比べて容易に設置できる。 On the other hand, the liquefied gas tank 1 of the present embodiment is provided with a drainer 5. For this reason, as shown by solid lines in FIGS. 1 and 2, the water W falls down from the lower end 52 of the water draining section 5 along the permeation suppressing member 62 and the outer peripheral surface of the water draining section 5, and each of the pipes 31, It does not reach 41 or each valve 32,42. Therefore, freezing of the pipes 31 and 41 and the valves 32 and 42 and generation of ice blocks F are suppressed, and it becomes easy to visually inspect defects such as liquid leakage and gas leakage therefrom.
In particular, when the liquefied gas tank 1 is installed in a cold area or a snowy area, the pipes 31 and 41 and the valves 32 and 42 are cooled by the outside temperature in addition to the liquefied gas G, and thus are easily frozen. By providing the portion 5, freezing and generation of the ice block F can be suppressed.
Further, since the water draining portion 5 separate from the tank main body 2 is fixed to the side surface 22, it can be easily installed as compared with the case where it is fixed to the lower surface 21 or the upper surface 23.

［変形例］
なお、本発明は上記実施形態にのみ限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々の改良ならびに設計の変更などが可能である。 [Modification]

水切り部５は、タンク本体２の上面２３や下面２１に設けられていてもよい。例えば、図３（Ａ）に示すように、下面２１における接続部分２１Ａ，２１Ｂの両方を囲む位置から下方に延びるように１つの水切り部５Ａを設けてもよいし、図３（Ｂ）に示すように、下面２１における接続部分２１Ａのみを囲む位置から下方に延びる水切り部５Ｂと、接続部分２１Ｂのみを囲む位置から下方に延びる水切り部５Ｃとを設けてもよい。 The drainer 5 may be formed of a metal other than SUS, resin, or the like, or may be integrally formed with the tank body 2.
The drainer 5 may be bent such that the lower end 52 is located outside or inside the upper end 51.
The method of fixing the drainer 5 to the side surface 22 is not limited to the method using the double-sided adhesive tape 61, but may be welding or screwing, for example. From the viewpoint, it is preferable to use the double-sided adhesive tape 61.
The drainer 5 may be provided on the upper surface 23 or the lower surface 21 of the tank body 2. For example, as shown in FIG. 3A, one drainer 5A may be provided so as to extend downward from a position surrounding both the connection portions 21A and 21B on the lower surface 21, or as shown in FIG. 3B. As described above, a water drain 5B extending downward from a position surrounding only the connection portion 21A on the lower surface 21 and a water drain 5C extending downward from a position surrounding only the connection 21B may be provided.
