従来上水道には幾つかの付属物が接続されている。例えば、水道メ−タ−（量 水器）は、水道配管システムには不可欠なものである。また、寒冷地などでは、 水道管の凍結を予防するために水抜き栓を取付け、気温が零度以下になるときな どに、この水抜き栓によって水道配管の立上がり管部分の水を取除いている。水 抜き栓や量水器などの付属物は適宜点検・修理や取換えを行っている。この水抜 き栓や量水器は、とくに寒冷地などでは、かなり地中深く埋設される。図５は、 それぞれ地中に埋設された量水器及び水抜き栓の１例である。量水器１も水抜き 栓２も地中に埋設、固定されている水道配管３に接続され、地中に埋設されてい るそれぞれの筐４に収納されている。なお、水道配管３の立上がり管の先端には 蛇口５が取付けられている。一般に、量水器などは、定期的に点検、取換えを行 うことが法的に定められており、筐を外し、土を掘り返して修理・消耗品の交換 を行うのを常としている。この量水器を直接水道配管に取付ける場合或いは水抜 栓を水道配管に取付ける場合などにおいて、地中に固定された水道配管に量水器 などの移動部材を固定するには、その水漏れ防止のためにパッキンを両者の間に 介在させている。 Conventionally, some accessories are connected to the water supply. For example, a water meter is an integral part of a water pipe system. Also, in cold regions, etc., install a water drain plug to prevent freezing of the water pipe, and use this water drain plug to remove water from the rising pipe part of the water pipe when the temperature falls below zero. There is. Accessories such as drain plugs and water meters are inspected, repaired and replaced as appropriate. These drain plugs and water meters are buried deep in the ground, especially in cold regions. FIG. 5 is an example of a water meter and a drain plug that are buried in the ground. Both the water meter 1 and the water drain plug 2 are connected to a water pipe 3 which is buried and fixed in the ground, and are housed in respective casings 4 buried in the ground. A faucet 5 is attached to the tip of the rising pipe of the water pipe 3. In general, water meters and other equipment are legally required to be inspected and replaced on a regular basis, and it is common practice to remove the casing, dig up the soil, and repair or replace consumables. When attaching this water meter directly to the water pipe or when attaching the water drain plug to the water pipe, fix the moving member such as the water meter to the water pipe fixed to the ground, and prevent water leakage. For this reason, packing is interposed between the two.
【０００３】 図６は、地中に固定されている水道配管３の端部と移動部材である量水器１の 端部の結合部分の断面図である。水道配管３は通常断面円筒状であり、その端部 の量水器端部との結合部は径大部３１になっており、他の部分とは段差ができて いる。一方、量水器１の端部１１も断面円筒状であり、水道配管３端部の径大部 ３１より幾分径が大きくなっている。そして、この量水器端部１１近辺には図示 のようにネジが切ってある。水道配管端部３１と量水器端部１１との間には、漏 水を防ぐために環状のパッキン７が挟み込まれている。この両端部を被覆するよ うにリング状のナット６が配置されている。そのナット６の内壁部にもネジが切 られていて、前記量水器端部３１およびその近辺に形成したネジに嵌まるように なっている。ナット６の一端には、内部方向に突出する突起部６１が在り、この 突起部６１と前記水道配管端部３１の径大部３１と嵌合するようになっている。 ナット６の一端に形成された突起部６１を水道配管端部３１の径大の突出部に引 っ掛けて量水器端部１１のネジにナット内壁のネジを嵌めて両者を締付けると、 両端部は密着する。FIG. 6 is a cross-sectional view of a connecting portion between the end of the water pipe 3 fixed to the ground and the end of the water meter 1 which is a moving member.

このように固定部材に移動部材を結合する場合において、とくに地中深く埋設 されている水道管に量水器や水抜き栓をユニオン結合する際には、パッキンを必 ず使用し、その気密性を高めなければならない。図６に示す使用例では、水道管 端部の径大部３１とほぼ同じ大きさのパッキン７の１面をこの端部に合わせ、他 面を量水器端部１１の端面に合わせる。この端面には溝が形成してあり、この溝 にパッキン７の面が強く押付けられて密着性を高くしている。パッキン７は殆ど 平面状になっており、パッキンの持つ弾性以上の圧力で水道配管３と量水器１を 圧着しないと、水圧Ｐによって水漏れが発生する。また、これらを地中で接続す る場合、パッキン７はナット６の内部に入れたまま、移動部材である量水器１と のネジ噛合わせをしなければならず、時にはパッキン７がナット６から外れて地 中に落下して両者の接合が不可能になることがある。 本考案は、この様な事情により成されたものであって、部材間のパッキンの装 着が確実に行われるユニオン結合装置を提供することを目的にしている。 When connecting a moving member to a fixed member in this way, especially when connecting a water meter or a drain plug to a water pipe buried deep in the ground, a packing must be used and its airtightness must be maintained. Must be raised. In the usage example shown in FIG. 6, one surface of the packing 7 having substantially the same size as the large-diameter portion 31 of the water pipe end is fitted to this end, and the other surface is fitted to the end face of the water meter end 11. A groove is formed on this end face, and the surface of the packing 7 is strongly pressed against this groove to enhance the adhesion. The packing 7 is almost flat, and unless the water pipe 3 and the water meter 1 are pressure-bonded with each other with a pressure higher than the elasticity of the packing, water pressure P causes water leakage. Also, when connecting these in the ground, the packing 7 must be screwed into the water meter 1 which is a moving member while the packing 7 is kept inside the nut 6. It may fall off the ground and fall into the ground, making it impossible to join the two. The present invention has been made under such circumstances, and an object of the present invention is to provide a union coupling device in which packing between members is reliably mounted.

FIG. 1 is a sectional view of a union coupling device, FIG. 2 is a sectional view of packing used in this union coupling device, FIG. 3 is a sectional view of the union coupling device used in a water meter, and FIG. FIG. 5 is a cross-sectional view when the union coupling device is used for a water drain plug, and FIG. 5 is a cross-sectional view showing a water meter equipped with this union coupling device and a purified body in which the water drain plug is buried in the ground. FIG. 1 is a cross-sectional view of a connecting portion between an end of a water pipe 3 fixed in the ground and an end of a water meter 1 which is a moving member. The water supply pipe 3 has a cylindrical shape, and the end of the water supply pipe 3 is connected to the end of the water meter to form a large-diameter portion 31, which forms a step with other portions. On the other hand, the end portion 11 of the water meter 1 is also cylindrical and has a diameter slightly larger than the large diameter portion 31 at the end portion of the water pipe 3. The water meter end portion 11 is threaded as shown. A packing 7 having a novel structure, which is a feature of the present invention, is sandwiched between the water pipe end 31 and the water meter end 11 to prevent water leakage.
【０００８】 このパッキンの断面図は図２（ａ）に示されている。また、この両端部を被覆 するようにリング状のナット６が配置されている。そのナット６の内壁部にもネ ジが切られていて、前記量水器端部３１に形成したネジに嵌まるようになってい る。ナット６の一端には、内部方向に突出する突出部６１が在り、この突出部６ １が前記水道配管端部の径大部３１に嵌合するようになっている。ナット６の突 出部６１を水道配管端部の径大部３１の突出部に引っ掛けて量水器端部１１のネ ジにナット内壁のネジを嵌めて両者を締めると両端部は密着する。図２（ａ）の パッキン７は、量水器１のネジ径に合う大径の本体部分と量水器３の内部に入る 小径部分の突出部７１とを備えている。そして、この実施例では、大径の本体部 分の内部に、圧力を利用して拡張することができる凹部７２を設け、小径の突出 部７１外周には複数の突起７３を形成している。A cross-sectional view of this packing is shown in FIG. Further, ring-shaped nuts 6 are arranged so as to cover both ends thereof. A screw is also cut on the inner wall portion of the nut 6 so that the nut 6 can be fitted into the screw formed on the water meter end portion 31. At one end of the nut 6, there is a protruding portion 61 that protrudes inward, and the protruding portion 61 is fitted into the large diameter portion 31 of the water pipe end portion. The projection 61 of the nut 6 is hooked on the projection of the large diameter portion 31 at the end of the water pipe, and the screw on the inner wall of the nut is fitted into the screw on the end of the water meter 11 and both ends are in close contact. The packing 7 in FIG. 2A includes a large-diameter main body portion that fits the screw diameter of the water meter 1 and a small-diameter protruding portion 71 that enters the inside of the water meter 3. In this embodiment, a concave portion 72 that can be expanded by utilizing pressure is provided inside the large-diameter main body portion, and a plurality of protrusions 73 are formed on the outer periphery of the small-diameter protruding portion 71.
【０００９】 このパッキンを用いて、図５に示すように、地中において水道配管３と量水器 １或いは水抜き栓２を接合するには、まず、例えば、量水器１の端部１１にパッ キン７を取付ける。パッキン７の突出部７１を量水器端部１１の凹部に差込む。 このとき、前記突出部７１の外周の突起７３は、この凹部側壁を押付けてパッキ ンの量水器からの抜けを防止する。パッキン７を量水器１の内部に装着してから 水道配管３の端部に装着されたナット６を量水器１にネジ込み、一定のトルクで 締付けると取付け作業は完了する。量水器端部１１のパッキン接触面には溝が形 成されており、この溝にパッキン接触面が強く押されてパッキンの密着性を向上 させている。さらにナット６の締付けが弱かったり、振動で締付け力が低下した 場合でも、パッキン７の大径の本体部分に形成した凹部７２には水道圧Ｐがかか っているので、この水道圧Ｐにより凹部７２が拡張されてパッキンと水道配管、 或いは、パッキンと量水器との間の漏水は防止される。In order to join the water pipe 3 and the water meter 1 or the water drain plug 2 in the ground using this packing as shown in FIG. 5, first, for example, the end portion 11 of the water meter 1 is connected. Install packing 7 on. The protruding portion 71 of the packing 7 is inserted into the concave portion of the water meter end portion 11. At this time, the projection 73 on the outer periphery of the projecting portion 71 presses the side wall of the recess to prevent the packing from coming off the water meter. When the packing 7 is mounted inside the water meter 1, the nut 6 mounted at the end of the water pipe 3 is screwed into the water meter 1 and tightened with a constant torque to complete the installation work. A groove is formed on the packing contact surface of the water meter end portion 11, and the packing contact surface is strongly pressed by the groove to improve the adhesion of the packing. Further, even when the nut 6 is weakly tightened or the tightening force is reduced by vibration, the water pressure P is applied to the recess 72 formed in the large-diameter main body portion of the packing 7, so that the water pressure P The recess 72 is expanded to prevent water leakage between the packing and the water pipe or between the packing and the water meter.
【００１０】 以上は、本発明に係るパッキンを水道配管と量水器との接合に適用した例につ いて説明したが、図４に示すように、このパッキンを水道配管と水抜き栓に適用 しても、その施工のし易さや気密性の高さは前述の実施例と同様に認められる。 本発明においては、前記構造のパッキン以外にも、例えば、図２（ｂ）に示す 構造のパッキンを用いても良い。これは、大径の本体部分の内部に凹部は形成し ておらず、また、小径の突出部７１に突起も形成されていないが、突出部がテ− パ状になっているので量水器１や水抜き栓２の凹部にパッキンの突出部７１が挿 入し易いという特徴を有している。The above has described the example in which the packing according to the present invention is applied to the connection between the water pipe and the water meter, but as shown in FIG. 4, the packing is applied to the water pipe and the water drain plug. Even so, the ease of construction and the high airtightness are recognized as in the above-mentioned embodiment. In the present invention, in addition to the packing having the above structure, for example, the packing having the structure shown in FIG. 2B may be used. This is because the concave portion is not formed inside the large-diameter main body portion and the small-diameter protruding portion 71 is not formed with a protrusion, but the protruding portion has a taper shape, and therefore the water meter. 1 has a feature that the protrusion 71 of the packing can be easily inserted into the recess of the drain plug 1 or the drain plug 2.
【００１１】[0011]
パッキンが確実に移動部材に装着できるので、固定部材に移動部材を容易に結 合させると共に、その気密性を十分向上させることができる。 Since the packing can be securely attached to the moving member, the moving member can be easily coupled to the fixed member and the airtightness thereof can be sufficiently improved.
