Description

本発明は、自動車やトラック・バスに搭載されるエンジンの冷却液が劣化しているかどうかを簡単に検査することができる冷却液検査具、及び冷却液の検査方法に関するものである。   The present invention relates to a coolant inspection tool and a coolant inspection method capable of easily inspecting whether coolant of an engine mounted on an automobile or a truck / bus has deteriorated.

自動車のエンジン用冷却液は、容易に沸騰蒸発せず、かつ、寒冷時でも凍結することがないように、エチレングリコールを主成分とする通年使用が可能な冷却液（Long Life Coolant −以下ＬＬＣと略称する）が一般的に用いられている。このＬＬＣは、冷却系を構成する金属に対する防食成分や殺菌、及び冷却効果を増す目的から、防錆剤、防腐剤、消泡剤等からなる溶剤が水と共に混合されている。   The coolant for automobile engines is a long life coolant (hereinafter referred to as “Long Life Coolant”), which can be used all year long, with ethylene glycol as the main component so that it does not evaporate easily and does not freeze even in cold weather. (Abbreviated) is generally used. In the LLC, for the purpose of increasing the anticorrosive component and sterilization of the metal constituting the cooling system and the cooling effect, a solvent composed of a rust inhibitor, an antiseptic, an antifoaming agent and the like is mixed with water.

ＬＬＣは使用時間の経過に伴い、エチレングリコールの酸化分解によりグリコール酸、蟻酸、酢酸などの有機酸類が生成するほか、接触する金属類の腐食により生成した鉄、銅、鉛、亜鉛などの重金属イオン、或いはこれらの金属の水酸化物や防食剤等の添加剤との反応生成物、或いはごみや油分の混入などにより、懸濁物が蓄積したりして徐々に劣化していく。従って、自動車等においては、通常、冷却液を所定期間の経過毎に交換するものとして、その旨が仕様説明書等に示されている。   With the lapse of time, LLC generates organic acids such as glycolic acid, formic acid, and acetic acid by oxidative decomposition of ethylene glycol, and heavy metal ions such as iron, copper, lead, and zinc generated by corrosion of metals that come into contact with LLC. Alternatively, suspension products accumulate or gradually deteriorate due to reaction products with additives such as metal hydroxides and anticorrosive agents, or contamination of dust or oil. Therefore, in an automobile or the like, normally, the fact that the coolant is exchanged every elapse of a predetermined period is shown in the specification manual or the like.

しかしながら、実際には一般的なユーザーは冷却液の品質にまで注意が及ぶことは少なく、購入時からは一度もラジエータキャップを開けたことがない、という具合にそのまま使い続けられることが殆どである。そこで、自動車への関心の高いガソリンスタンド等においては、給油時におけるサービスの一環として冷却液の品質をチェックすることがしばしば行われている。従来の冷却液のチェックとしては、特許文献１において開示されているように、ラジエータからサンプルとして取り出した少量の冷却液の比重を測定（即ち、ＬＬＣに含まれている腐食防止剤の濃度を測定）して、新品の冷却液の比重と比較することで劣化具合を判断する、という手段が採られていた。
特開昭５７−１１７３３８号公報 However, in practice, general users rarely pay attention to the quality of the cooling liquid, and since the purchase, the radiator cap has never been opened, and it is almost always possible to continue using it as it is. . Therefore, at a gas station or the like that is highly interested in automobiles, it is often performed to check the quality of the coolant as part of the service at the time of refueling. As a conventional coolant check, as disclosed in Patent Document 1, the specific gravity of a small amount of coolant taken out from the radiator as a sample is measured (that is, the concentration of the corrosion inhibitor contained in the LLC is measured). ) And determining the degree of deterioration by comparing with the specific gravity of a new coolant.
JP 57-117338 A

上述の比重を用いた検査は、まず吸出し具等によってラジエータから少量の冷却液を取り出し、その取り出された冷却液を比重測定器に供給することによって行われるのであるが、比重測定器が高価であるとともに、採取したサンプルを比重測定器から元のラジエータに戻す人為作業が面倒でもあることから、ある程度規模の大きい量販ガソリンスタンド店等の一部を除いては実質的に実現不可能なものであった。   The inspection using the above-mentioned specific gravity is performed by first taking out a small amount of cooling liquid from the radiator with a sucking tool and the like and supplying the extracted cooling liquid to the specific gravity measuring device. However, the specific gravity measuring device is expensive. In addition, the manual work of returning the collected sample from the specific gravity measuring instrument to the original radiator is cumbersome, so it is practically impossible to achieve except for some large-scale gas station gas stations. there were.

本発明の目的は、冷却液を泡立てた後の泡の消え難さから冷却液の劣化度合いが判断可能であるという新たな認識に着目し、その現象を利用することにより、簡単で廉価に冷却液の劣化具合をチェックできる改善された冷却液検査具を実現し、提供する点にある。   The object of the present invention is to focus on the new recognition that the degree of deterioration of the coolant can be judged from the difficulty of disappearance of the foam after the coolant is bubbled.

請求項６に係る発明は、請求項１〜５の何れか一項に記載の冷却液検査具において、前記比較タンクｈｔが複数装備されていることを特徴とするものである。   The invention according to claim 6 is characterized in that in the coolant inspection tool according to any one of claims 1 to 5, a plurality of the comparison tanks ht are provided.

請求項７に係る発明は、冷却液の検査方法において、請求項１〜６の何れか一項に記載の冷却液検査具Ａを、前記比較タンクｈｔに劣化していない冷却液ｇｗ，ｒｗが貯留されている状態で用意し、前記サンプルタンクｓｔに少量の冷却液ｓｗを採取してから前記冷却液検査具Ａを所定回数シェイクし、それからサンプルタンクｓｔ内に採取されている冷却液ｓｗと前記比較タンクｈｔに貯留されている冷却液ｇｗ，ｒｗとを設定時間に亘って目視比較することを特徴とするものである。   The invention according to claim 7 is the coolant inspection method, wherein the coolant inspection tool A according to any one of claims 1 to 6 is not changed to the comparison tank ht. Prepared in a stored state, a small amount of the coolant sw is collected in the sample tank st, and then the coolant inspection tool A is shaken a predetermined number of times, and then the coolant sw collected in the sample tank st The coolants gw and rw stored in the comparison tank ht are visually compared over a set time.

請求項１や請求項７の発明によれば、次のような効果が得られる。即ち、自動車エンジン用等の冷却液には、ラジエータとの密着性を良くして冷却能力を上げるために消泡剤が入れられており、泡が立ったとしても直ぐに消失するようになっている。つまり、劣化していない（新品等）冷却液を激しく振って泡立てても、消泡剤の作用によって瞬時にして泡が消えてしまうのである。これに対して、経時変化等によって冷却液が劣化して行くと、冷却効果を増すための消泡剤の作用も次第に弱まるため、泡が次第に消失され難くなること（冷却液を泡立てた後の泡の消失速度が次第に遅くなること）となり、泡がなかなか消えなくなることが知見されている。本発明はこの原理を応用したものである。   According to the first and seventh aspects of the invention, the following effects can be obtained. In other words, anti-foaming agents are included in the coolant for automobile engines and the like in order to improve the adhesion with the radiator and increase the cooling capacity, and even if bubbles are formed, they disappear immediately. . That is, even if a non-degraded (new product, etc.) coolant is shaken vigorously, the bubbles disappear instantaneously due to the action of the antifoaming agent. On the other hand, when the cooling liquid deteriorates due to a change over time or the like, the action of the antifoaming agent for increasing the cooling effect is gradually weakened, so that bubbles are hardly lost (after the foaming of the cooling liquid). It has been found that the disappearance speed of the bubbles gradually decreases) and the bubbles do not disappear easily. The present invention applies this principle.

要するに、少量採取されたサンプル冷却液をシェイクして泡立たせ、その後に泡が迅速に消えるかどうかを劣化していない冷却液と比較しながら見ることにより、冷却液の劣化がどれだけ進行しているかを判断することが可能である。請求項１による冷却液検査具や請求項７による冷却液の検査方法は、上述の原理を用いた目視チェックを簡単で便利に行えるように工夫されたものであり、冷却液採取手段によってサンプルタンクに採取されているサンプル冷却液と、劣化していない冷却液とを備える検査具やそれを用いた検査方法である。つまり、サンプル冷却液が採取されている状態で検査具を強制的にシェイクして各冷却液を泡立たせ、サンプル冷却液の泡の消えて行く速度を劣化していない冷却液のものと目視で比較することにより、サンプル冷却液がどの程度劣化しているのかを即座に知ることが可能になる。   In short, how much deterioration of the coolant has progressed by shaking a small sample of the sample coolant and bubbling it, then looking at whether the bubbles disappear quickly compared to an undegraded coolant. It is possible to determine whether or not The coolant inspection tool according to claim 1 and the coolant inspection method according to claim 7 are devised so that a visual check using the above-mentioned principle can be performed easily and conveniently, and a sample tank is provided by the coolant sampling means. And an inspection method using the inspection tool including the sample cooling liquid collected in the above and a non-deteriorated cooling liquid. In other words, forcibly shake the test tool while the sample coolant is collected to make each coolant foam, and visually check that the coolant that has not deteriorated the speed at which the bubbles of the sample coolant disappear. By comparing, it is possible to immediately know how much the sample coolant has deteriorated.

その結果、冷却液を泡立てた後の泡の消え難さから冷却液の劣化度合いが判断可能であるという認識に着目し、その現象を利用することにより、簡単で廉価に冷却液の劣化具合をチェックできる改善された冷却液検査具、並びに冷却液の検査方法を実現して提供することができる。   As a result, paying attention to the recognition that the degree of deterioration of the cooling liquid can be judged from the difficulty of disappearance of the foam after bubbling the cooling liquid, and using this phenomenon, the deterioration degree of the cooling liquid can be easily and inexpensively determined. An improved coolant inspection tool that can be checked and a coolant inspection method can be realized and provided.

請求項２の発明によれば、サンプルタンクへの冷却液の採取を可能とする開き状態と、サンプルタンクに採取された冷却液の外部への漏れ出しを阻止する閉じ状態との切換が可能な開閉弁が装備されているので、開閉弁を開き状態として良好にサンプル冷却液を採取することができるとともに、開閉弁を閉じ状態として各冷却液を泡立たせるべく検査具を振る（シェイク）することが、冷却液の漏れ出しを気にすることなく行うことができる。つまり、開閉弁の設置により、冷却液の採取操作と検査具の振り操作との双方を冷却液の採取困難や漏れ出しのおそれが無く、簡単で確実に検査可能な冷却液検査具を提供することができる。   According to the second aspect of the present invention, it is possible to switch between an open state in which the coolant can be collected in the sample tank and a closed state in which the coolant collected in the sample tank is prevented from leaking to the outside. Since the on / off valve is equipped, the sample coolant can be collected well with the on / off valve open, and the test tool is shaken to shake each coolant with the on / off valve closed. However, it can be performed without worrying about leakage of the coolant. In other words, by providing an on-off valve, there is provided a coolant inspection tool that can easily and reliably inspect both the coolant sampling operation and the inspection tool swinging operation without the risk of coolant sampling difficulty or leakage. be able to.

請求項３の発明によれば、冷却液採取手段が、サンプルタンクにホースと弾性袋とを設けてのスポイト構造、即ち人為操作によって冷却液を吸い上げるものであるから、他に動力源が不要であって構造が簡単で廉価なものとなる利点がる。   According to the invention of claim 3, since the coolant collecting means is a dropper structure in which a hose and an elastic bag are provided in the sample tank, that is, the coolant is sucked up by human operation, no other power source is required. Therefore, there is an advantage that the structure is simple and inexpensive.

請求項４の発明によれば、請求項３のものと同様に冷却液採取手段がスポイト構造で構成されており、その吸い上げ部分が可撓ホースとされているから、請求項３の発明による前期効果を有するとともに、冷却液の採取場所が自動車ボンネット内に配置されるラジエータや、運転座席下方に配置されるラジエータ等、奥まった箇所や入り組んだ箇所にも可撓ホースを難無く配策させることができ、冷却液の採取状況を労せずして作り出すことが可能になる便利さがある。そして、開閉弁の開閉切換が、内弁筒部と外弁筒部との相対回動操作によって簡単で軽快に行えるという取扱い性に優れる利点もある。   According to the invention of claim 4, since the coolant collecting means is constituted by a dropper structure as in the case of claim 3, and the suction part is a flexible hose, the first period according to the invention of claim 3 In addition to having an effect, the flexible hose can be routed without difficulty in places that are deep or intricate, such as radiators that are placed in the hood of the coolant and radiators that are placed under the driver's seat. This is convenient because it makes it possible to produce the cooling liquid without making effort. Further, there is an advantage in excellent handleability that switching between opening and closing of the opening / closing valve can be easily and easily performed by a relative rotation operation between the inner valve cylinder portion and the outer valve cylinder portion.

請求項５の発明のように取っ手を設けることにより、持ち易く、かつ、振り易くなって使い勝手がより改善されるものになり、請求項６のように比較タンクを２個以上設ける構成とすれば、市販されている互いに色の異なる複数種の冷却液をそれぞれ常備可能となり、より扱い易く使い易い冷却液検査具を提供することができる。   By providing a handle as in the invention of claim 5, it is easy to hold and swing, and the usability is further improved. As in claim 6, two or more comparison tanks are provided. A plurality of types of commercially available cooling liquids having different colors can be provided, and a cooling liquid inspection tool that is easier to handle and easier to use can be provided.

以下に、本発明による冷却液検査具、及び冷却液の検査方法の実施の形態を、図面を参照しながら説明する。図１は冷却液検査具の全体図、図２〜図５は開閉弁に関する各図、図６は取っ手取付構造に関する図、図７〜図９は冷却液検査具を用いた検査方法を示す作用図である。   Hereinafter, embodiments of a coolant inspection tool and a coolant inspection method according to the present invention will be described with reference to the drawings. 1 is an overall view of a coolant inspection tool, FIGS. 2 to 5 are views relating to an on-off valve, FIG. 6 is a view relating to a handle mounting structure, and FIGS. 7 to 9 are views showing an inspection method using the coolant inspection tool. FIG.

〔実施例１〕
実施例２による冷却液検査具Ａは、図１，図２に示すように、自走車両からエンジン冷却液を採取可能な冷却液採取手段１と、採取された少量の冷却液ｓｗを貯留するためのサンプルタンクｓｔと、劣化していない冷却液ｇｗ，ｒｗを貯留可能な比較タンクｈｔ，ｈｔと、開閉弁３と、取っ手４とを有して構成されている。サンプルタンクｓｔと、その上部の両脇に一体形成される一対の比較タンクｈｔ，ｈｔとによって検査本体２が構成されており、この検査本体２は、透明プラスチックを用いた型成形によって形成されている。 [Example 1]
As shown in FIGS. 1 and 2, the coolant inspection tool A according to the second embodiment stores coolant sampling means 1 that can collect engine coolant from a self-propelled vehicle and a small amount of coolant sw that has been collected. Sample tank st, comparison tanks ht and ht capable of storing coolants gw and rw that have not deteriorated, an on-off valve 3, and a handle 4. An inspection body 2 is constituted by a sample tank st and a pair of comparison tanks ht and ht integrally formed on both sides of the upper part of the sample tank st. The inspection body 2 is formed by molding using a transparent plastic. Yes.

冷却液採取手段１は、自動車に搭載されるラジエータ３０の冷却液供給口３１に挿入可能な径に設定されてサンプルタンクｓｔの下端（一端の一例）に接続されるゴムホース（可撓ホースの一例）５と、サンプルタンクｓｔの上端（他端の一例）に接続されるゴム袋（弾性袋の一例）６と、サンプルタンクｓｔとから成るスポイト構造に構成されている。つまり、ゴム袋６を手指で摘み潰した状態でゴムホース５をラジエータ３０の冷却液供給口３１に差し込み、それからゴム袋６の握りを緩めて復元膨張させることにより、負圧による吸引力で少量の冷却液をサンプルタンクｓｔ内に吸い込んで採取することができる。   The coolant sampling means 1 is a rubber hose (an example of a flexible hose) that is set to a diameter that can be inserted into a coolant supply port 31 of a radiator 30 mounted on an automobile and is connected to the lower end (one example of one end) of the sample tank st. ) 5, a rubber bag (an example of an elastic bag) 6 connected to the upper end (an example of the other end) of the sample tank st, and a dropper structure including the sample tank st. In other words, the rubber hose 5 is inserted into the coolant supply port 31 of the radiator 30 while the rubber bag 6 is crushed with fingers, and then the rubber bag 6 is loosened and restored and expanded, so that a small amount of suction force due to negative pressure can be obtained. The coolant can be drawn into the sample tank st and collected.

サンプルタンクｓｔは、図１〜図３に示すように、両脇に比較タンクｈｔ，ｈｔを備える小径の上部貯留部７と、大径の下部貯留部８とから成る略フラスコ状の形状であり、下部貯留部８の下端部には開閉弁３が構成されている。各比較タンクｈｔは、無蓋筒状に形成されており、その上部開口部９には冷却液を封入するための栓１０が装備される。取っ手４は、下部貯留部８の外周部における所定箇所と、一方の比較タンクｈｔの外周部とに形成される互いに同構造で形状は異なる取付部１１，１１を用いて一体的に装備されている。   As shown in FIGS. 1 to 3, the sample tank st has a substantially flask-like shape composed of a small-diameter upper reservoir 7 having comparative tanks ht and ht on both sides and a large-diameter lower reservoir 8. The open / close valve 3 is configured at the lower end of the lower storage portion 8. Each comparison tank ht is formed in an open cylinder shape, and the upper opening 9 is equipped with a stopper 10 for enclosing a coolant. The handle 4 is integrally mounted using attachment portions 11 and 11 having the same structure and different shapes formed at a predetermined location on the outer peripheral portion of the lower storage portion 8 and the outer peripheral portion of one comparison tank ht. Yes.

即ち、図６に示すように、一方の比較タンクｈｔの上部外側には上側のみ傾斜しての先細り状で板状の突片である上係合突起１３Ａが一体形成されるとともに、サンプルタンクｓｔの外周部における上係合突起１３Ａの直下となる位置には、上側のみオーバーハング傾斜しての先拡がり状で板状の突片である下係合突起１３Ｂが一体形成されている。取っ手４の上端部には上取付部１３Ａと同じ側面視形状の上凹入部１２Ａが、そして下端部には下取付部１３Ｂと同じ側面視形状の下凹入部１２Ｂがそれぞれ形成されている。つまり、上取付部１３Ａと上凹入部１２Ａとで、及び下係合突起１３Ｂと下凹入部１２Ｂとでそれぞれ取付部１１が形成される。   That is, as shown in FIG. 6, an upper engaging protrusion 13A, which is a tapered plate-like protruding piece that is inclined only on the upper side, is integrally formed on the upper outer side of one comparison tank ht, and the sample tank st A lower engaging protrusion 13B, which is a flared plate-like protruding piece with an overhanging inclination only on the upper side, is integrally formed at a position directly below the upper engaging protrusion 13A in the outer peripheral portion of the outer peripheral portion. An upper recessed portion 12A having the same side view shape as the upper mounting portion 13A is formed at the upper end portion of the handle 4, and a lower recessed portion 12B having the same side view shape as the lower mounting portion 13B is formed at the lower end portion. That is, the attachment portion 11 is formed by the upper attachment portion 13A and the upper recess portion 12A, and by the lower engagement protrusion 13B and the lower recess portion 12B.

従って、図１，図６に示すように、取っ手４を検査本体２に押付けながら上方移動させて、上凹入部１２Ａに上係合突起１３Ａを、かつ、下凹入部１２Ｂに下係合突起１３Ｂをそれぞれ無理入れ嵌合させることにより、取っ手４の取付座４ａ，４ａのそれぞれが、下部貯留部８の外周面８ａ及び比較タンクｈｔの外周面とに接する（又はほぼ接する）状態で取っ手４を検査本体２に一体的に装着することができる。この場合、各係合突起１３Ａ，１３Ｂの横先端部の上下に亘って厚みが増された縦膨張部を形成し、かつ、各凹入部１２Ａ，１２Ｂの内奥側の上下に亘って縦膨張部に嵌合する嵌合溝部を形成することにより、取っ手４の検査本体への装着状態における取っ手４の検査本体２に対する横側方への抜け止め作用が強化される構造としても良い。   Accordingly, as shown in FIGS. 1 and 6, the handle 4 is moved upward while being pressed against the inspection body 2, and the upper engaging protrusion 13A is formed in the upper recessed portion 12A and the lower engaging protrusion 13B is formed in the lower recessed portion 12B. Forcibly inserting and fitting the handle 4 in a state where each of the mounting seats 4a, 4a of the handle 4 is in contact with (or substantially in contact with) the outer peripheral surface 8a of the lower reservoir 8 and the outer peripheral surface of the comparison tank ht. The inspection body 2 can be attached integrally. In this case, a vertical expansion portion having an increased thickness is formed across the top and bottom of the lateral tip of each of the engagement protrusions 13A and 13B, and the vertical expansion is performed over the top and bottom of the inner side of each of the recessed portions 12A and 12B. It is good also as a structure which strengthens the anti-detaching action to the side of the inspection main body 2 of the handle 4 in the state where the handle 4 is attached to the inspection main body by forming the fitting groove portion to be fitted to the portion.

このように、検査本体２と取っ手４とを別部品として組付けて一体化する構造を採ることにより、検査本体２の金型が構造簡単で廉価なもので済むので、取っ手４専用の金型が別に必要であはるが、検査本体２と取っ手４とを一体成形する場合に比べてトータルコストを下げることに成功している。尚、一方の比較タンクｈｔには新品で赤色の冷却液（ＬＬＣ）ｒｗを貯留させておき、他方の比較タンクｈｔには緑色の冷却液（ＬＬＣ）ｇｗを貯留させておく。   In this way, by adopting a structure in which the inspection body 2 and the handle 4 are assembled and integrated as separate parts, the mold of the inspection body 2 can be simple and inexpensive. However, although it is necessary, it has succeeded in reducing the total cost as compared with the case where the inspection body 2 and the handle 4 are integrally formed. One comparison tank ht stores new red coolant (LLC) rw, and the other comparison tank ht stores green coolant (LLC) gw.

開閉弁３は、図３〜図５に示すように、検査本体２の下端部に液密に螺装可能な内弁筒部１５と、これに螺着されるゴムホース５の連結が可能な外弁筒部１４とから構成されている。つまり、外弁筒部１４を内弁筒部１５に対して左に回す弛め操作を行うと、スポイド作用によって冷却液を吸い上げることが可能となるように内外の弁筒部１５，１４が連通する状態になり、外弁筒部１４を内弁筒部１５に対して右に回す締め込み操作を行うと、サンプルタンクｓｔ内に貯留されている冷却液が内弁筒部１５から外弁筒部１４に落下移動するのを阻止するように、内外の弁筒部１５，１４の連通を遮断する状態になる。   As shown in FIGS. 3 to 5, the on-off valve 3 has an inner valve cylinder portion 15 that can be screwed in a liquid-tight manner to the lower end portion of the inspection body 2 and a rubber hose 5 that is screwed to the outer valve tube portion 15. It consists of a valve cylinder part 14. In other words, when the loosening operation of turning the outer valve cylinder portion 14 counterclockwise with respect to the inner valve cylinder portion 15 is performed, the inner and outer valve cylinder portions 15 and 14 communicate with each other so that the coolant can be sucked up by the spoid action. When the tightening operation of turning the outer valve cylinder portion 14 clockwise with respect to the inner valve cylinder portion 15 is performed, the coolant stored in the sample tank st is transferred from the inner valve cylinder portion 15 to the outer valve cylinder. The communication between the inner and outer valve cylinders 15 and 14 is cut off so as to prevent the drop movement to the part 14.

図３〜図５に示すように、内弁筒部１５は、サンプルタンクｓｔ下端部に螺合可能な雌ネジ部１６ａを備える装着筒部１６と、外弁筒部１４に螺合可能な雄ネジ部１７ａを備える内嵌合筒部１７と、内嵌合筒部１７の底壁１７Ａに開口される連通円孔１８とを有する合成樹脂製のものに構成されている。外弁筒部１４は、雄ネジ部１７ａに螺合可能な雌ネジ部１９ａを備える外嵌合筒部１９と、その下方の装着筒部２０とを有する合成樹脂製のものに構成されている。外嵌合筒部１９の底壁１９Ａには、連通円孔１８に密内嵌する山状突起２１と、その裾に連なる止め周面２２と、この止め周面２２の外周側に位置する三箇所の連通円弧２３とが形成されている。山状突起２１の上部は、その表面が半球状面に形成されている。   As shown in FIGS. 3 to 5, the inner valve cylinder portion 15 includes a mounting cylinder portion 16 having a female screw portion 16 a that can be screwed to the lower end portion of the sample tank st, and a male screw that can be screwed to the outer valve cylinder portion 14. The inner fitting cylinder part 17 provided with the screw part 17a and the communication circular hole 18 opened to the bottom wall 17A of the inner fitting cylinder part 17 are made of a synthetic resin. The outer valve cylinder part 14 is comprised by the synthetic resin thing which has the outer fitting cylinder part 19 provided with the internal thread part 19a which can be screwed together in the external thread part 17a, and the mounting cylinder part 20 below it. . On the bottom wall 19 </ b> A of the outer fitting cylinder portion 19, there are a mountain-like protrusion 21 that is tightly fitted in the communication circular hole 18, a stop peripheral surface 22 that continues to the hem, and three outer peripheral sides of the stop peripheral surface 22. The communication arc 23 of the location is formed. The upper surface of the mountain-shaped protrusion 21 has a hemispherical surface.

ゴムホース５の上端部は、合成樹脂製の取付用筒２４下部の小径筒部２４ａに弾性外嵌装着されており、取付用筒２４上部の大径筒部２４ｂが装着筒部２０に密外嵌可能な寸法に設定されている。大径筒部２４ｂの上端には、環状内周突起２４ｃが形成され、かつ、装着筒部２０の下部外周には周溝２０ａが形成されており、大径筒部２４ｂと装着筒部２０との無理入れ及び無理抜きにより、環状内周突起２４ｃと周溝２０ａとが互いに嵌り合う取付用筒２４の装着状態（図２参照）、並びに取外し状態の選択が自在である。   The upper end portion of the rubber hose 5 is elastically fitted to a small-diameter cylindrical portion 24a at the bottom of the mounting cylinder 24 made of synthetic resin, and the large-diameter cylindrical portion 24b at the top of the mounting cylinder 24 is tightly fitted to the mounting cylindrical portion 20. Set to possible dimensions. An annular inner peripheral projection 24c is formed at the upper end of the large diameter cylindrical portion 24b, and a circumferential groove 20a is formed at the lower outer periphery of the mounting cylindrical portion 20, and the large diameter cylindrical portion 24b, the mounting cylindrical portion 20, By forcibly inserting and forcibly removing, the mounting state (see FIG. 2) of the mounting cylinder 24 in which the annular inner peripheral protrusion 24c and the circumferential groove 20a are fitted to each other and the removal state can be selected freely.

さて、開閉弁３の作用を説明すると、まず、外弁筒部１４を右に回してその回動が止まるまで締め切る閉じ位置ｂに操作すると、図２に示すように、外弁筒部１４の山状突起２１が連通円孔１８に挿入され、かつ、内嵌合筒部１７の底壁１７Ａにおける連通円孔１８の周囲部分が止め周面２２に当接されて、外弁筒部１４と内弁筒部１５との連通が遮断される開閉弁３の閉じ状態が得られる。そして、閉じ位置ｂから外弁筒部１４を左に少し回して若干下がった開き位置ａに操作すると、図５に示すように、山状突起２１が連通円孔１８から抜出すように外弁筒部１４が内弁筒部１５に対して下方に移動するので、三箇所の連通円弧２３と連通円孔１８とを介して外弁筒部１４と内弁筒部１５とが連通される開閉弁３の開き状態が得られる。   Now, the operation of the on-off valve 3 will be described. First, when the outer valve cylinder portion 14 is rotated to the right and operated to the closed position b where the rotation stops until the rotation stops, as shown in FIG. The mountain-shaped protrusion 21 is inserted into the communication circular hole 18, and the peripheral portion of the communication circular hole 18 in the bottom wall 17 </ b> A of the inner fitting cylindrical portion 17 is brought into contact with the stop peripheral surface 22, A closed state of the on-off valve 3 in which communication with the inner valve cylinder portion 15 is blocked is obtained. Then, when the outer valve cylinder portion 14 is slightly rotated counterclockwise from the closed position b and operated to the open position a slightly lowered, the outer valve 21 is pulled out from the communication hole 18 as shown in FIG. Since the cylinder part 14 moves downward with respect to the inner valve cylinder part 15, the outer valve cylinder part 14 and the inner valve cylinder part 15 communicate with each other via the three communication arcs 23 and the communication circular hole 18. An open state of the valve 3 is obtained.

次に、本発明による冷却液検査具Ａを用いた冷却液の検査方法を、例としてガソリンスタンドにおいて行うものとして説明する。まず、図７に示すように、外弁筒部１４を左方向に捻って回動させて開閉弁３を開き位置ａに切換えてからゴムホース５をラジエータ３０の冷却液供給口３１に挿入し、冷却液採取手段１のスポイト操作（ゴム袋６を握り潰し、かつ、復元させる操作）により、ラジエータ３０内の冷却液（冷却水）を少量吸い取ってサンプルタンクｓｔに採取するサンプル採取工程を行う。尚、サンプルタンクｓｔに採取されたサンプル冷却液ｓｗは、後述の視認工程の終了後に、開閉弁３を開き操作して元のラジエータ３０に戻すのが望ましい。   Next, a cooling liquid inspection method using the cooling liquid inspection tool A according to the present invention will be described as being performed at a gas station as an example. First, as shown in FIG. 7, the outer valve cylinder 14 is twisted to the left and turned to switch the on-off valve 3 to the open position a, and then the rubber hose 5 is inserted into the coolant supply port 31 of the radiator 30. A sample collecting step is performed in which a small amount of cooling liquid (cooling water) in the radiator 30 is sucked and collected in the sample tank st by the dropper operation of the cooling liquid collecting means 1 (operation to squeeze and restore the rubber bag 6). It is desirable that the sample coolant sw collected in the sample tank st is returned to the original radiator 30 by opening the on-off valve 3 after completion of the visual recognition process described later.

サンプル採取工程では、サンプルタンクｓｔにサンプル冷却液ｓｗが採取できたら、外弁筒部１４を締め切るまで右に回して閉じ位置ｂに操作することにより、開閉弁３を開き状態から閉じ状態に切換えておく。それから、図８に示すように、取っ手４を介して手指で持っている冷却液検査具Ａを、勢い良く数回（所定回数）上下に（前後左右でも良い）振り、各冷却液ｓｗ，ｇｗ，ｒｗが十分に泡立つようにシェイクする泡立て工程を行う。そして、十分泡立ったら冷却液検査具Ａを止め、それから図９に示すように、ドライバーＭ等の面前に位置させて静止させ、暫く（数秒間）目ｍで各タンクｈｔ，ｓｔ内の状況を見て確認させる視認工程を行う。   In the sample collection process, when the sample coolant sw is collected in the sample tank st, the on-off valve 3 is switched from the open state to the closed state by rotating it to the right until the outer valve cylinder 14 is closed and operating to the closed position b. Keep it. Then, as shown in FIG. 8, the coolant inspection tool A held by a finger through the handle 4 is vigorously shaken up and down several times (predetermined number of times) (before and after and left and right), and each coolant sw, gw , Rw is shaken so as to be sufficiently bubbled. Then, when the foam is sufficiently bubbled, stop the coolant inspection tool A, and then place it still in front of the driver M or the like as shown in FIG. A visual recognition process is performed to make it look and confirm.

即ち、一瞬のうちに泡が消えて行く新品の各冷却液ｒｗ，ｇｗと、サンプル冷却液ｓｗの泡の無くなって行く様子とを同時に見て比較することにより、交換しなければならない程サンプル冷却液ｓｗが劣化している（泡が殆ど消えて行かない状態）のか、やや劣化している（泡がゆっくりと消えて行く状態）のか、まだ新しい（迅速に泡が消えて行く状態）のかといった具合に判断することができる。この場合、図９に示すように、ある程度の時間が経過してもサンプル液の泡が殆ど消えないことが視認されると、ラジエータ３０の冷却液が劣化していることの証拠となるので、納得のゆくかたちでドライバーに冷却液の交換を勧めることが可能になる。   That is, the sample cooling liquid rw, gw in which bubbles disappear in an instant and the state of disappearance of bubbles in the sample cooling liquid sw are simultaneously viewed and compared, so that the sample cooling has to be replaced. Whether the liquid sw has deteriorated (the bubbles hardly disappear), is slightly deteriorated (the bubbles disappear slowly), or is still new (the bubbles disappear quickly) It can be judged properly. In this case, as shown in FIG. 9, when it is visually confirmed that the bubbles of the sample liquid hardly disappear even after a certain amount of time has passed, it becomes evidence that the cooling liquid of the radiator 30 has deteriorated. It is possible to advise the driver to change the coolant in a convincing way.
