Abstract
Description
本発明は、主として集合住宅や戸建て住宅の水周りに使用されるパイプ継手に関するものである。 The present invention relates to a pipe joint mainly used around the water of an apartment house or a detached house.
近年、水周りのパイプは金属管を使用するよりも可撓性のある樹脂パイプが広く用いられるようになった。しかるに、金属管を含めてパイプはどこに用いられるかによって太さが何種類もあり、これに従って継手も多くの種類があり、その大きさは直接比較して大きさを判別していた。 In recent years, flexible resin pipes have been widely used as pipes around water rather than using metal pipes. However, there are several kinds of thickness depending on where the pipes including the metal pipe are used, and there are many kinds of joints according to this, and the sizes are directly compared to determine the size.
しかしながら、その大きさはかなり近接したものであり、かつ、継手自体がほぼ同じような色調であるため、目視にて確実に判断することは難しい面があった。このため、在庫状況の確認の際に間違ったり、作業現場でのサイズの取り違えもままあり、簡便な継手の大きさの確認方法が要請されていた。 However, the sizes are quite close to each other, and the joints themselves have almost the same color tone, so that it is difficult to make a reliable judgment visually. For this reason, there are some mistakes in checking the stock status, and there is a mix-up of the sizes at the work site, and a simple method for checking the size of the joint has been demanded.
本発明は継手の大きさ(サイズ)を目視によって簡単にかつ確実に判断できるようにしたもので、特に、継手のソケットにプラスチック製品を用いる構造のものに適用したものである。 The present invention is such that the size (size) of the joint can be easily and reliably determined by visual observation, and is particularly applied to a structure using a plastic product for the socket of the joint.
本発明の要旨は、パイプを連結する継手基体と樹脂製のソケットからなるパイプ継手のサイズの識別方法であって、前記ソケットにサイズ別に別の色彩を施したことを特徴とするパイプ継手のサイズの識別方法である。 The gist of the present invention is a method for identifying the size of a pipe joint comprising a joint base for connecting pipes and a resin socket, wherein the socket has a different color according to size. It is an identification method.
上記したように、本発明はパイプ継手のサイズの識別を簡単に判別する方法を提供するものであり、これによってパイプに対する継手のサイズを間違えることがなくなったものであり、配管現場での手違い等がなくなったものである。 As described above, the present invention provides a method for easily discriminating the size of the pipe joint size, which eliminates the mistake in the size of the joint for the pipe. Is gone.
本発明は以上の通りであり、継手基体に嵌合される樹脂製のソケットに色彩を施すものであって、これによって継手のサイズを簡単に確認できることとなったものである。 The present invention is as described above, and colors are applied to a resin socket fitted to a joint base, whereby the joint size can be easily confirmed.
継手基体は金属製(砲金)でも樹脂製でもよく、ソケットは樹脂製であって、ポリエチレン、ナイロン等にて製造されたものであり、その他、いわゆるエンジニアプラスチック製のものである。 The joint base may be made of metal (gun metal) or resin, and the socket is made of resin, made of polyethylene, nylon or the like, and also made of so-called engineer plastic.
これら樹脂ソケットの着色は特に限定するものではないが、色素、即ち、染料や顔料がプラスチック材料中に配合されて色彩が施されるものである。色素中に内でも、通常は種々の無機顔料又は有機顔料を用いることができる。継手基体が樹脂製の場合には、基体も同色の色彩が施されるのが最も好ましいことは言うまでもない。 The coloring of these resin sockets is not particularly limited, but a coloring matter, that is, a dye or a pigment is blended in a plastic material to give a color. In the dye, various inorganic pigments or organic pigments can be usually used. Needless to say, when the joint base is made of resin, it is most preferable that the base is also colored in the same color.
無機顔料としては、金属酸化物、金属錯塩等で示される金属化合物であり、具体的には鉄、コバルト、アルミニウム、カドミウム、鉛、銅、チタン、マグネシウム、クロム、亜鉛、アンチモン等の金属酸化物、及び前記金属の複合酸化物を挙げることができる。 Examples of inorganic pigments are metal compounds such as metal oxides and metal complex salts. Specifically, metal oxides such as iron, cobalt, aluminum, cadmium, lead, copper, titanium, magnesium, chromium, zinc, and antimony And composite oxides of the above metals.
有機顔料としては、ピグメントイエロ−ll,24,31等、ピグメントオレンジ36,38,43等、ピグメントレッドlO5,122,149等、ピグメントバイオレット19,23,32等、ピグメントブル−l,2,15等、ピグメントグリ−ン7,36,37等、ピグメントブラウン25,28等、ピグメントブラックl,7等を挙げることができる。 Examples of organic pigments include Pigment Yellow-ll, 24, 31 etc., Pigment Orange 36, 38, 43 etc., Pigment Red 10, 122, 149 etc., Pigment Violet 19, 23, 32 etc., Pigment Bull-1, 2, 15 Pigment Green 7, 36, 37, Pigment Brown 25, 28, Pigment Black 1, 7, and the like.
赤の顔料としては、アントラキノン系顔料、ペリレン系顔料、緑の顔料としては、ハロゲン化フタロシアニン系顔料、青の顔料としては、フタロシアニン系顔料、黒色の顔料としては、カーボン、チタンカーボン等が用いられる。 Anthraquinone pigments, perylene pigments are used as red pigments, halogenated phthalocyanine pigments are used as green pigments, phthalocyanine pigments are used as blue pigments, and carbon and titanium carbon are used as black pigments. .
ソケットの着色方法は、マスタ−バッチ法、練り込み法、顔料表面コ−ト法、ドライブレンド法等があるが、例えば、マスタ−バッチ法とは顔料等を被着色材料に混ぜ合わせて使用する方法、練り込み法とは材科ペレツトに顔料を混ぜ合わせて押出を行い、色付きのペレツトにする方法、顔料表面コ−ト法とは色を付けたい材料ペレットの表面に、顔料を溶かした塗料を吹き付けてコ−ティングする方法である。エンジニアプラスチックのように融点の高い樹脂では、主に無機系の金属化合物が用いられ、顔料の添加量は一般的に0.5%程度である。 The socket coloring method includes a master batch method, a kneading method, a pigment surface coating method, a dry blend method and the like. For example, the master batch method is used by mixing a pigment or the like with a material to be colored. The method, kneading method is a method in which pigments are mixed with material pellets and extruded to make colored pellets. The pigment surface coating method is a paint in which pigments are dissolved on the surface of the material pellets to be colored. It is a method of spraying and coating. In the case of a resin having a high melting point such as an engineer plastic, an inorganic metal compound is mainly used, and the amount of pigment added is generally about 0.5%.
図1はパイプ継手の分解図であり、1は金属製の継手基体、2は樹脂製のソケットである。継手基体1は内部に流路1aが形成され、この流路1aに段部1bが形成されてここにO−リング1c及びパイプ保持リング1dが嵌め込まれる。パイプ保持リング1dは樹脂製のリングであり、複数のスリット1eとその間に爪1fが備えられている。このため、差し込まれるパイプ10の表面にこの爪1fが食い込み、更にそのスリット1eの分だけ縮径するので、パイプ10の脱落が阻止されることになる。
FIG. 1 is an exploded view of a pipe joint, where 1 is a metal joint base and 2 is a resin socket. The joint base 1 has a flow path 1a formed therein, a step portion 1b is formed in the flow path 1a, and an O-ring 1c and a pipe holding ring 1d are fitted therein. The pipe holding ring 1d is a resin ring and includes a plurality of slits 1e and claws 1f therebetween. For this reason, the claw 1f bites into the surface of the
一方、ソケット2はナイロン製であり、これらのO−リング1c及びパイプ保持リング1dの抜けを防止し、かつ、パイプ保持リングの縮径を促すように傾斜した内径2aを備えたものであり、差し込まれたパイプが抜け出ようとした際には、パイプ保持リング1dがかかる傾斜内径2aに接触して縮径し、爪1fの食い込みが更に増すという構造になっている。 On the other hand, the socket 2 is made of nylon, and has an inner diameter 2a that is inclined so as to prevent the O-ring 1c and the pipe holding ring 1d from coming off and to promote the diameter reduction of the pipe holding ring. When the inserted pipe is about to come out, the pipe holding ring 1d comes into contact with the inclined inner diameter 2a to reduce the diameter, and the claw 1f bites further.
ソケット2を得る際の概略を述べると、ナイロン製のソケット2に黒色の色彩が施されたものであり、カ−ボンブラックを含んだナイロンべ−スのマスタ−バッチを備え、成形時にナイロン樹脂ペレットに混ぜ合わせ、これを型内にいれて架橋成形して黒色の色彩を持った樹脂ソケット2が得られることになる。特に、カ−ボンブラックの場合には、少量の含有量でも得られた製品には黒色がはっきり出る。このカ−ボンブラックの含有量は樹脂に対し0.1重量%の単位の含有量で十分である。 The outline for obtaining the socket 2 is as follows. The nylon socket 2 is provided with a black color and is provided with a nylon-based masterbatch containing carbon black. The resin socket 2 having a black color is obtained by mixing with the pellet and placing it in a mold and performing cross-linking molding. In particular, in the case of carbon black, a black color appears clearly in the product obtained even with a small content. A content of 0.1% by weight of the carbon black is sufficient with respect to the resin.
継手基体1がナイロン樹脂製のものである場合には、かかるマスタ−バッチをそのまま用いればよく、この場合には黒色の継手基体と黒色のソケットとは一対のものとして扱われ、その継手(継手基体とソケット)のサイズは一目見て明確に判断でき、特に現場での間違いは全くなくなることになる。 When the joint base 1 is made of nylon resin, such a master batch may be used as it is. In this case, the black joint base and the black socket are treated as a pair, and the joint (joint The size of the base body and the socket) can be clearly determined at a glance, and there will be no errors in the field.
本発明はパイプ継手のサイズの識別を簡単に判別する方法を提供するものであり、パイプの接続作業のあらゆる箇所において作業ミスがなくなるという大きな特徴があり、特に水周りでの接続作業にあっては漏水の発生は極めて低減できたものである。 The present invention provides a method for easily discriminating the identification of the size of a pipe joint, and has a great feature that work errors are eliminated at all points of pipe connection work, particularly in connection work around water. The occurrence of water leakage was extremely reduced.
