【考案の属する技術分野】[Technical field to which the invention belongs]

本考案は住宅用の上水道管として布設されている給水管の内面に発生した錆を 一世帯単位で溶解除去するための錆溶解用薬液を用いた給水管内面の錆除去装置 に関するものである。 The present invention relates to an apparatus for removing rust from the inner surface of a water supply pipe using a rust dissolving chemical for dissolving and removing rust generated on the inner surface of a water supply pipe laid as a residential water supply pipe per household.

【0002】[0002]

【従来の技術】[Prior art]

住宅用の上水道管として布設されている給水管は、一般に、地中からの立ち上 り部以降には亜鉛メッキ鋼管が使用されているため、使用環境にも依るが、通常 、2〜3年で酸化作用が始まり、10年程度経過すると、空気中で鉄が錆るのと 同様に、水中でも管内面に徐々に腐食が生じて、水の使い始めに錆の混入した赤 水が出てくるようになり、更に老朽化が進むと、錆が増えることと錆にごみが付 着することにより蛇口から出る水の圧力が低くなってしまうという不具合が発生 するだけでなく、赤水を飲用することによる健康への影響が懸念されるという問 題がある。 Water supply pipes laid as residential water pipes generally use galvanized steel pipes after rising from the ground, so depending on the usage environment, they usually take 2-3 years. Oxidation begins to take place after about 10 years, just like iron rusts in the air, as well as the corrosion of the inner surface of the pipe gradually in water, and rusted red water comes out at the beginning of water use. As the aging progresses, the rust increases and the rust adheres to the dirt, lowering the pressure of the water coming out of the faucet, and drinking red water. There is a concern that the impact of this on health may be a concern.

【0003】 したがって、赤水が出た場合には、給水管の内面に発生している錆を除去して 給水管の更生を図り、従前の状態に機能回復させることが必要となる。[0003] Therefore, when red water comes out, it is necessary to remove rust generated on the inner surface of the water supply pipe to rehabilitate the water supply pipe and restore its function to the previous state.

【0004】 給水管内面の錆を除去する方法の一つとして、薬液により管内の錆を溶解させ る方法がある。この錆溶解用の薬液を用いる場合、たとえば、マンションの如き 多世帯用の建物内に布設されている給水管を対象とする場合には、屋上に設置さ れている高架水槽内に薬液を入れ、各世帯に備え付けられているすべての蛇口( 給水栓)を所要時間開いて、薬液をすべての給水管を通して蛇口まで行き届かせ るようにした後、すべての蛇口を閉じて一定時間放置させるようにすることが従 来より行われている。[0004] As one method of removing rust on the inner surface of a water supply pipe, there is a method of dissolving rust in the pipe with a chemical solution. When using this chemical for dissolving rust, for example, when targeting water pipes laid in a multi-family building such as an apartment, put the chemical in an elevated water tank installed on the rooftop. Open all faucets (water taps) provided for each household for a required time to allow the chemical to reach the faucet through all water pipes, and then close all faucets and let them stand for a certain period of time. Has been done in the past.

【0005】[0005]

【考案が解決しようとする課題】 ところが、上記のような錆溶解用薬液による給水管内面の錆除去の場合、集合 住宅のすべてを対象としなければならず、一世帯単位で実施することはできなか った。すなわち、マンションやビル等では、地中に埋設されている水道管本管か ら給水管先端の蛇口に至るまでの給水系路の途中に、高架水槽という大気開放部 が存在するため、全世帯を対象として給水管内へ薬液を注入することは可能であ るが、多世帯のうち一世帯の給水管にのみ選択して薬液を注入することはできず 、又、戸建て住宅等では、給水系路の途中に大気開放部がないことから、薬液を 給水管内に注入することができなかった。又、仮りに、給水管の途中に大気開放 部を形成したとしても、高架水槽の如く重力を利用しての薬液の送り込みはでき ないので、たとえば、圧力の高いポンプ等を使用することになるが、その場合、 送り込み圧力を調整することができないので、各蛇口からは薬液が一気に流出し てしまい、薬液の流出具合を見て直ちに薬液の送り込みを停止させる等の操作が 困難で、無駄に流してしまう薬液の量が多くなってしまうものと予想される。[Problems to be solved by the present invention] However, in the case of removing rust on the inner surface of the water supply pipe with the chemical solution for dissolving rust as described above, it is necessary to cover all apartment buildings, and it is not possible to carry out one household at a time. It was not. In other words, in condominiums and buildings, all households have an elevated water tank in the middle of the water supply system from the water pipe main buried underground to the faucet at the end of the water supply pipe. It is possible to inject chemicals into the water supply pipes for water supply, but it is not possible to selectively inject the chemicals into the water supply pipes of only one household out of many households. Since there was no open air partway along the road, the chemical could not be injected into the water supply pipe. Also, even if an atmosphere opening part is formed in the middle of the water supply pipe, the chemical solution cannot be sent using gravity like an elevated water tank, so a high-pressure pump, for example, will be used. However, in this case, since the feeding pressure cannot be adjusted, the chemical solution flows out from each faucet at a stretch, and it is difficult to stop the feeding of the chemical solution immediately after observing the condition of the chemical solution, which is wasteful. It is expected that the amount of the chemical solution that will flow will increase.

【0006】 そこで、本考案は、戸建て住宅のみならず、集合住宅でも一世帯ごとに給水管 の錆除去を、必要最少量の薬液を用いるだけで実施することができるような錆溶 解用薬液を用いた給水管内面の錆除去装置を提供しようとするものである。[0006] Therefore, the present invention provides a rust-dissolving chemical solution that can remove rust from a water supply pipe for each household not only in a detached house but also in an apartment house using only the minimum necessary amount of the chemical solution. An object of the present invention is to provide an apparatus for removing rust on the inner surface of a water supply pipe using the same.

【課題を解決するための手段】[Means for Solving the Problems]

本考案は、上記課題を解決するために、錆溶解用薬液を収容した圧力タンクと 送風機とを持ち運び可能に備えて、該圧力タンク内の錆溶解用薬液の上方空間を 加圧して錆溶解用薬液に圧力タンク外への押し出し圧力を付与できるように、上 記送風機に接続したエア吐出管を圧力タンクの上部に連通接続し、且つ上記圧力 タンクの天井部を貫通させて圧力タンク内に挿入した薬液取出管の一端を錆溶解 用薬液中に没入してタンク内底面付近に位置させると共に、該薬液取出管の他端 を、給水管の上流側端部に一端を接続させるようにする薬液送給ホースの他端に 接続するようにし、更に、上記圧力タンクの天井部に、圧力タンク内のエアの圧 力を調整するためのエア抜きコックを備えたエア抜き管を接続した構成とする。 In order to solve the above-mentioned problems, the present invention provides a pressure tank containing a rust-dissolving chemical and a blower so as to be portable, and pressurizes the space above the rust-dissolving chemical in the pressure tank to dissolve the rust. An air discharge pipe connected to the blower is connected to the upper part of the pressure tank so that the chemical can be pushed out of the pressure tank, and inserted into the pressure tank through the ceiling of the pressure tank. One end of the drained chemical solution pipe is immersed in the chemical solution for dissolving rust and positioned near the bottom surface of the tank, and the other end of the chemical solution discharge pipe is connected to one end of the upstream end of the water supply pipe. It is configured to be connected to the other end of the supply hose, and further connected to the ceiling of the pressure tank with an air release pipe provided with an air release cock for adjusting the pressure of air in the pressure tank. .

【0008】 戸建て住宅等の給水管内面の錆を除去する場合、給水管の途中に設けられてい る止水栓を閉じてからメーターを取り外して、メーター取付部よりも下流に位置 する給水管の基端に薬液送給ホースを接続した状態として、送風機の運転により 圧力タンク内に圧送したエアの圧力で、圧力タンク内の薬液を、薬液取出管から 薬液送給ホースを通して少しずつ給水管内に注入してすべての蛇口を開き、蛇口 から薬液が流出するようになると蛇口を閉じ、送風機の運転を停止して管内に薬 液を一定時間滞留させた後、薬液送給ホースを給水管から取り外してメーターを 取り付け、止水栓と蛇口を開いて、蛇口から出る水が透明になれば蛇口を閉じる ようにする。[0008] When removing rust on the inner surface of a water supply pipe of a detached house or the like, a water stopcock provided in the middle of the water supply pipe is closed, then the meter is removed, and the water supply pipe located downstream of the meter mounting portion is removed. With the chemical supply hose connected to the base end, the chemical in the pressure tank is gradually injected into the water supply pipe from the chemical extraction pipe through the chemical supply hose by the pressure of the air pumped into the pressure tank by the operation of the blower. When all the taps are opened and the chemicals start flowing out of the taps, close the taps, stop the operation of the blower and allow the chemicals to stay in the pipes for a certain period of time, then remove the chemical supply hose from the water supply pipe. Attach the meter, open the stopcock and faucet, and close the faucet when the water coming out of the faucet becomes clear.

【0009】 又、薬液取出管の他端に、口径の異なる2種類の薬液供給管を三方切替コック を介して接続し、且つ各薬液供給管の先端に、それぞれ薬液送給ホースを接続で きるようにした構成とすることにより、給水管の口径に合う薬液供給管と薬液送 給ホースを選択して使用することができるので、1台の清掃装置で口径の異なる 2種類の給水管の清掃を行うことができる。In addition, two types of liquid supply pipes having different diameters can be connected to the other end of the liquid discharge pipe via a three-way switching cock, and a liquid supply hose can be connected to the tip of each liquid supply pipe. With this configuration, it is possible to select and use a chemical supply pipe and a chemical supply hose that match the diameter of the water supply pipe, so that one cleaning device can clean two types of water supply pipes having different diameters. It can be performed.

Air in the space The chemical solution 12 pushed into the chemical solution discharge pipe 15 from the chemical solution suction port 15 a by the pressure of the chemical solution supply port 17 or 18 by operating the three-way switching cock 16 and the opening / closing cock 19, passes the chemical solution supply hose 21. Through the water pipe.

【0013】 更に、上記圧力タンク11の天井部所要個所に、圧力計22及び安全弁23を 取り付けたゲージ管24を圧力タンク11内と連通するように立てて、圧力タン ク11内のエア圧力を監視できるようにし、且つ上記ゲージ管24の途中に、エ ア抜きコック25を備えたエア抜き管26を分岐接続して、エア抜きコック25 の操作で圧力タンク11内のエア14を抜くことにより、圧力タンク11内の圧 力を調整して薬液送給ホース21を通しての薬液12の送給流量を制御できるよ うにし、更に、上記圧力タンク11の側壁下部に、ドレン弁27を備えたドレン 抜き管28を接続して、圧力タンク11内のドレンを抜けるようにする。Further, a gauge tube 24 having a pressure gauge 22 and a safety valve 23 attached thereto is set up at a required location on the ceiling of the pressure tank 11 so as to communicate with the inside of the pressure tank 11, and the air pressure in the pressure tank 11 is reduced.

Further, a drain valve 27 having a drain valve 27 is provided at a lower part of the side wall of the pressure tank 11. A drain pipe 28 is connected to drain the drain in the pressure tank 11.

【0014】 図1中、CVは薬液供給管17と18の途中に設けた逆止弁を示す。In FIG. 1, CV indicates a check valve provided in the middle of the chemical supply pipes 17 and 18.

【0015】 上記において、薬液取出管15の薬液取出口15bに、口径が20mmの薬液 供給管17と口径が13mmの薬液供給管18を三方切替コック16を介して接 続したのは、一般住宅に布設されている給水管の口径が20mmのものと13m mのものにほぼ(90%以上)2分されるので、これらいずれの口径の給水管に 対しても適用できるようにするためである。In the above description, the chemical liquid supply pipe 17 having a diameter of 20 mm and the chemical liquid supply pipe 18 having a diameter of 13 mm are connected to the chemical liquid outlet 15 b of the chemical liquid outlet pipe 15 via the three-way switching cock 16. The diameter of the water supply pipes laid in this area is divided into two (approximately 90% or more) of 20 mm and 13 mm, so that it can be applied to water pipes of any of these diameters. .

【0016】 上記構成としてある本考案の錆除去装置を用いて、たとえば、戸建て住宅に布 設されている給水管内面の錆を除去するための清掃を行う場合は、給水管の途中 に取り付けられているメーターを取り外して、メーターを取り外した後の下流側 の給水管の基端に、上記薬液送給ホース21の先端部を接続して給水管に薬液1 2を小流量として送り込むようにする。When the rust removing device of the present invention having the above configuration is used to clean, for example, rust on the inner surface of a water supply pipe laid in a detached house, the rust removal apparatus is installed in the middle of the water supply pipe. After removing the meter, the distal end of the chemical solution supply hose 21 is connected to the base end of the water supply tube on the downstream side after the meter is removed, and the chemical solution 12 is fed into the water supply tube at a small flow rate. .

【0017】 詳述すると、図2にその一例の概略を示す如く、戸建て住宅29用の給水管3 0は、道路31等の下の地中に埋設されている水道管本管32から分岐させられ て、住宅29の敷地内の地中を経由して住宅29内に引き込まれ、先端に給水栓 としての蛇口33が取り付けられており、且つ敷地内の地中に位置する途中には 、上流側から順に止水栓34とメーター35とが取り付けられている。More specifically, as schematically shown in FIG. 2, a water supply pipe 30 for a detached house 29 is branched from a water pipe main pipe 32 buried in the ground under a road 31 or the like. Then, it is drawn into the house 29 via the ground in the premises of the house 29, and a faucet 33 as a water tap is attached to a tip thereof. A water stopcock 34 and a meter 35 are attached in order from the side.

【0018】 したがって、予め、圧力タンク11内に所要量(たとえば、10リットル)の 有色の錆溶解用薬液12を収容させておき、且つ適用する給水管30の口径と同 じ口径の薬液供給管17又は18に、対応する薬液送給ホース21を取り付けて おいた状態として、上記止水栓34を閉じた後、メーター35を取り外し、該メ ーター35の取付位置よりも下流に位置する給水管30の基端部に薬液送給ホー ス21の先端部を接続具20を介して接続させるようにする。この際、図1にお いて実線で示す如く、薬液送給ホース21を薬液供給管17に接続する場合は、 開閉コック19を閉じ、三方切替コック16を、薬液供給管17と薬液取出管1 5とが連通する位置に切り替えておくようにする。Therefore, a required amount (for example, 10 liters) of the colored rust-dissolving chemical solution 12 is stored in the pressure tank 11 in advance, and the chemical solution supply pipe having the same diameter as the diameter of the water supply pipe 30 to be applied. With the corresponding chemical solution supply hose 21 attached to 17 or 18, the water stopcock 34 is closed, the meter 35 is removed, and the water supply pipe located downstream from the mounting position of the meter 35 is removed. The distal end of the chemical solution feeding hose 21 is connected to the base end of the hose 30 via the connector 20. At this time, as shown by the solid line in FIG. 1, when connecting the chemical supply hose 21 to the chemical supply pipe 17, the open / close cock 19 is closed, and the three-way switching cock 16 is connected to the chemical supply pipe 17 and the chemical extraction pipe 1. 5 is switched to a position where it communicates.

【0019】 上記の状態において、送風機8のスイッチ7を入れて送風機8の運転を開始さ せるようにすると、送風機8からエア吐出管13を通って圧力タンク11内にエ ア14が圧送されるため、圧力タンク11内の薬液12の上方空間の圧力が高く なることに伴って、下端の薬液吸入口15aから薬液取出管15内に薬液12が 押し込まれ、更に、薬液供給管17及び薬液送給ホース21を経由して給水管3 0内に薬液12が少量ずつ送り込まれることになる。この際、圧力計22により 圧力タンク11内の圧力を監視し、圧力が設定値よりも高くなるような場合は、 エア抜きコック25を操作して余剰のエア14をエア抜き管26を通して抜くよ うにして、薬液12が給水管30内に少量宛送り込まれるように調整する。住宅 29内にあるすべての蛇口33を開くと、給水管30内の水は蛇口33から流出 し、薬液12が給水管30内を下流側へ移って行く。給水管30に取り付けてあ る蛇口33から有色の薬液12が小流量で流出してくると、その蛇口33を閉じ るようにし、以後同様にしてすべての蛇口33から薬液12の流出が確認される と、すべての蛇口33を閉じるようにする。これにより、薬液12はすべての給 水管30内に行き届いたことになるので、次に、三方切替コック16を操作して 薬液供給管17を閉じると共に送風機8の運転を停止し、薬液12により給水管 30の内面の錆が溶解されるまでの一定時間だけそのまま放置させるようにする 。In the above state, when the switch 7 of the blower 8 is turned on to start the operation of the blower 8, the air 14 is pressure-fed from the blower 8 through the air discharge pipe 13 into the pressure tank 11. Therefore, as the pressure in the space above the chemical solution 12 in the pressure tank 11 increases, the chemical solution 12 is pushed into the chemical solution discharge pipe 15 from the chemical solution suction port 15a at the lower end, and further, the chemical solution supply pipe 17 and the chemical solution delivery The chemical solution 12 is fed little by little into the water supply pipe 30 via the supply hose 21. At this time, the pressure in the pressure tank 11 is monitored by the pressure gauge 22, and when the pressure becomes higher than the set value, the air bleed cock 25 is operated to bleed the excess air 14 through the air bleed pipe 26. Thus, adjustment is made so that the chemical solution 12 is sent into the water supply pipe 30 in a small amount. When all the faucets 33 in the house 29 are opened, the water in the water supply pipe 30 flows out of the faucet 33, and the chemical solution 12 moves down the water supply pipe 30 to the downstream side. When the colored chemical solution 12 flows out of the faucet 33 attached to the water supply pipe 30 at a small flow rate, the faucet 33 is closed, and thereafter the outflow of the chemical solution 12 from all the faucets 33 is confirmed. Then, all the faucets 33 are closed. As a result, the chemical liquid 12 has reached all the water supply pipes 30. Next, the three-way switching cock 16 is operated to close the chemical liquid supply pipe 17 and stop the operation of the blower 8. The tube 30 is allowed to stand for a certain period of time until the rust on the inner surface is dissolved.

【0020】 一定時間経過後、給水管30から薬液供給ホース21を取り外し、続いて、取 り外しておいたメーター35を給水管30に取り付けてから止水栓34を開き、 更に、すべての蛇口33を開くようにする。これにより、しばらくすると、蛇口 33から流出する水が透明になるので、その時点でその蛇口30を閉じるように し、すべての蛇口30から透明な水が流出するようになってすべての蛇口30を 閉じることで、給水管30の錆除去作業を終了する。以上の錆除去作業を定期的 に実施することにより、給水管30の健全性を長期に亘り維持することができる 。After a certain period of time, the chemical supply hose 21 is removed from the water supply pipe 30. Subsequently, the meter 35 that has been removed is attached to the water supply pipe 30 and then the water stopcock 34 is opened. Open 33. As a result, after a while, the water flowing out of the faucet 33 becomes transparent, so that the faucet 30 is closed at that time, and the clear water flows out from all the faucets 30, and all the faucets 30 are flushed. By closing, the rust removal operation of the water supply pipe 30 is completed. By regularly performing the above rust removal work, the soundness of the water supply pipe 30 can be maintained for a long time.

【0021】 上記において、送風機8から圧送するエア14の圧力はポンプで発生させる圧 力よりも低いので、エア抜きコック25の操作で容易に調整することができ、こ の調整した圧力により薬液12を給水管30内に少量宛送り込んで先端の蛇口3 3まで行き届かせるようにするので、蛇口33からは薬液12が一気に流出する ことはなく、小流量状態で流出することから、流出する薬液12の色の濃さ(水 が混入しているか否か)等の様子を見ながら蛇口33を閉じたり開いたりして、 薬液12の送り込み、停止を余裕をもって行うことができ、これにより、使用す る薬液12を必要最少量で済ますことができる。In the above, since the pressure of the air 14 pumped from the blower 8 is lower than the pressure generated by the pump, the pressure can be easily adjusted by operating the air bleeding cock 25. Is fed into the water supply pipe 30 in a small amount so as to reach the faucet 33 at the tip, so that the chemical solution 12 does not flow out at once from the faucet 33 but flows out at a small flow rate. The faucet 33 can be closed and opened while observing the state of the color density (whether or not water is mixed in) 12 and the like, so that the chemical solution 12 can be sent and stopped with a sufficient margin, thereby enabling the use of the chemical solution 12. The required amount of the chemical solution 12 can be reduced to the minimum required.

【0022】 なお、上記実施の形態では、口径が20mmの給水管であっても13mmの給 水管であっても対応できるように、薬液取出管15の薬液取出口15bに口径が 20mmの薬液供給管17と口径が13mmの薬液供給管18を分岐接続するよ うにした場合を示したが、上記いずれか一方の給水管のみの専用の錆除去装置と する場合には、薬液取出管15の口径を20mm又は13mmとして、その先端 部付近に開閉コックを設けて、薬液送給ホース21を接続するようにしてもよい こと、又、安全弁23とエア抜きコック25は兼用のものを用いるようにしても よいこと、更に、実施の形態では、運搬台車1上に送風機8や加圧タンク11を 搭載した場合を示したが、持ち運びすることができれば運搬台車1を使用しなく てもよいこと、戸建て住宅の場合について示したが、集合住宅の一世帯用として も適用できること、その他本考案の要旨を逸脱しない範囲内において種々変更を 加え得ることは勿論である。In the above-described embodiment, the supply of a chemical solution having a diameter of 20 mm to the chemical solution outlet 15 b of the chemical solution outlet pipe 15 is performed so that the water supply pipe having a diameter of 20 mm or the water supply pipe having a diameter of 13 mm can be used. The case where the pipe 17 and the chemical solution supply pipe 18 having a diameter of 13 mm are branched and connected is shown. However, when a dedicated rust removing device for only one of the water supply pipes is used, the diameter of the chemical solution discharge pipe 15 is determined. May be set to 20 mm or 13 mm, and an opening / closing cock may be provided in the vicinity of the distal end to connect the chemical solution supply hose 21. Also, the safety valve 23 and the air release cock 25 may be combined. In addition, in the embodiment, the case where the blower 8 and the pressurized tank 11 are mounted on the transport trolley 1 has been described, but if the transport trolley 1 can be carried, the transport trolley 1 is not used. Although the description has been made on the case of a detached house, it is apparent that the present invention can be applied to a single-family apartment, and that various changes can be made without departing from the scope of the present invention.
