(57) [Summary] (Modified) [Purpose] Since a valve device for controlling the maximum flow rate is added to the free pipe used by connecting to a faucet such as a sink, the maximum flow rate set according to the application is supplied. Can be controlled without being affected by. Prevents problems such as scattering due to excessively coming out and adverse effects from the neighborhood such as water hammers in multi-dwelling houses. [Structure] A straight pipe portion 2a near the inlet or outlet of the universal pipe 2
A piston 4 having an orifice therein is slidably inserted so as to receive a spring reaction force against the water flow, and the amount of water passing through the orifice increases, and the thrust force due to the pressure difference generated before and after the orifice is increased. When the spring reaction force is exceeded, the piston moves and the needle valve 4b integral with it moves.
Closes the second orifice communicating with the discharge port to restrict the water flow, and the piston rests at a position where the thrust and the spring reaction force are balanced to regulate the maximum flow rate. The maximum flow rate can be set arbitrarily by changing the relative distance between the needle valve and the second orifice with the knob.
Description
【0001】[0001]
本考案は水道の水栓本体に接続して用いられる自在管の改良に関する。 The present invention relates to an improvement of a universal pipe used by being connected to a water faucet body.
【0002】 具体的にいえば、水圧の高低にかかわらず使用目的に応じて最大流量を適正値 に設定できるように改善するものである。[0002] Specifically, the improvement is made so that the maximum flow rate can be set to an appropriate value according to the purpose of use regardless of the level of water pressure.
【0003】[0003]
従来の自在管2は図1に示すように、水栓本体1の吐出口にナット3で旋回自 在に接続されていて、図2にその接続の構造を示す。 As shown in FIG. 1, a conventional universal pipe 2 is connected to a discharge port of a water faucet body 1 by a nut 3 in a rotating manner, and FIG. 2 shows the connection structure.
【0004】 すなわち自在管2の接続側にナット3、止め輪33を挿入し、止め輪33を自 在管2に絞り成形した溝に嵌めて固定し、さらにパッキング32とスペーサー3 1を挿入し、自在管2の先端を水栓本体1の吐出口に挿入してナット3を水栓本 体1に螺合して構成されている。That is, the nut 3 and the retaining ring 33 are inserted into the connecting side of the universal pipe 2, the retaining ring 33 is fitted and fixed in the groove formed in the free pipe 2 by drawing, and the packing 32 and the spacer 31 are further inserted. The tip of the flexible tube 2 is inserted into the discharge port of the faucet body 1 and the nut 3 is screwed into the faucet body 1.
【0005】 従って自在管の目的は単に水の出口の位置を変えることのみに留まる。The purpose of the universal tube is therefore merely to change the position of the water outlet.
【0006】[0006]
近年、高層のビルや集合住宅が増えてきて、一つの給水源からの分岐が多くな る傾向があり、また高階層と低階層との水圧差の増大や水打現象など他室の水栓 の開閉にともなう不都合が多くなっている。 In recent years, the number of high-rise buildings and apartments has increased, and there is a tendency for more branches to come from one water supply source. There are many inconveniences associated with opening and closing.
【0007】 例えば水圧が高いところでは適切な流量調節がしにくいため、必要以上の水が 流れて貴重な水資源が無駄になったり、また台所の流し台で洗い物をしている最 中、隣室の水栓が急に閉じられて流量が急増し飛沫が周囲に飛散したり衣服が濡 れるなどの不具合はしばしば経験するところである。For example, when the water pressure is high, it is difficult to properly control the flow rate, so more water flows than necessary and valuable water resources are wasted. Also, while washing in the sink in the kitchen, We often experience problems such as sudden closing of the faucet, rapid increase in flow rate, splashing of splashes, and wetting of clothes.
【0008】 また操作の便利さから普及しつつあるシングルレバー型の水栓においてはレバ ーの操作ストロークが小さく流量の調節がしにくい欠点があり、しばしば水の浪 費につながっている。In addition, single lever type faucets, which are becoming popular due to their convenience of operation, have a drawback that the operation stroke of the lever is small and it is difficult to adjust the flow rate, which often leads to waste of water.
【0009】[0009]
本考案はこのような従来の欠点をなくするため、交換部品としても広く市販さ れている自在管の改良によって、配管や水栓本体に手を加えることなく、一般家 庭の主婦にでも簡単に装着できるようにするとともに、安価に実施できる方法を 提供しようとするものである。 In order to eliminate such conventional drawbacks, the present invention is an easy-to-use even for housewives in general households by improving the universal pipe that is widely marketed as a replacement part without touching the piping or faucet body. It is intended to provide a method that can be mounted on the vehicle and can be implemented at low cost.
【0010】 具体的には図3の実施例に示すごとく、従来の自在管2における接続側にT字 状に直管部2aを設けて、水栓本体1との接続は従来と同等の方法でできるよう にする。Specifically, as shown in the embodiment of FIG. 3, a T-shaped straight pipe portion 2a is provided on the connection side of the conventional universal pipe 2, and the connection with the faucet body 1 is performed by the same method as the conventional one. I will be able to.
【0011】 直管部2aの内部にはシリンダーを形成し、オリフィス4aと針弁4bを有す るピストン4を摺動自在に嵌挿し、一端を直管部2aに形成したネック2bによ って支持されたスプリング41によって常に水流に抗する方向に押されるように 支持する。A cylinder is formed inside the straight pipe portion 2a, a piston 4 having an orifice 4a and a needle valve 4b is slidably fitted and inserted, and a neck 2b having one end formed in the straight pipe portion 2a is used. The spring 41 is supported so that it is always pushed in the direction against the water flow.
【0012】 ピストン4の上方への移動は直管部2aに形成した溝に嵌挿した止め輪42に よって拘束されている。The upward movement of the piston 4 is restrained by a retaining ring 42 fitted in a groove formed in the straight pipe portion 2a.
【0013】 スライダー5とホルダー51は一体に溶接されていて、上端にはオリフィス4 aよりも十分大きいオリフィス5aが、また側面には多数の通し孔5bが設けて あり、常にスライダー5の内部すなわち流出室Cと自在管2は連通している。The slider 5 and the holder 51 are integrally welded, and an orifice 5a that is sufficiently larger than the orifice 4a is provided at the upper end, and a large number of through holes 5b are provided on the side surface. The outflow chamber C and the free pipe 2 communicate with each other.
【0014】 スライダー5はオリフィス5aがピストン4の下端に設けた針弁4bに対向す るように直管部2aに嵌挿されていて、ピストン4がいっぱいに下降したとき針 弁4bがオリフィス5aを塞ぐようになっている。The slider 5 is fitted into the straight pipe portion 2a so that the orifice 5a faces the needle valve 4b provided at the lower end of the piston 4, and when the piston 4 is fully lowered, the needle valve 4b is inserted into the orifice 5a. Is designed to block.
【0015】 ホルダー51の下部にはツマミ52がセレーション嵌合していて小ねじ54で 一体に固定されている。A knob 52 is fitted to the lower portion of the holder 51 by serration and is fixed integrally with a machine screw 54.
【0016】 ツマミ52は直管部2aの下端に設けたネジに螺合していて、手でツマミ52 を回すことによりツマミ52、ホルダー51、スライダー5は一体に回転しなが ら上下に移動できるようになっている。The knob 52 is screwed into a screw provided at the lower end of the straight pipe portion 2a, and by rotating the knob 52 by hand, the knob 52, the holder 51 and the slider 5 move up and down while rotating integrally. You can do it.
【0017】 以上説明したように直管部2aおよびスライダー5の内部はオリフィス4aと オリフィス5aによって流入室A、中間室B、流出室Cに区画されることになり 、水栓本体1、流入室A、中間室B、流出室C、自在管2の流路が構成される。As described above, the interiors of the straight pipe portion 2a and the slider 5 are divided into the inflow chamber A, the intermediate chamber B, and the outflow chamber C by the orifice 4a and the orifice 5a. A, the intermediate chamber B, the outflow chamber C, and the flow path of the universal tube 2 are configured.
【0018】[0018]
水栓本体1がわずかに開かれて少量の水が流れるとき、図3に示すように、オ リフィス4aの前後すなわち流入室Aと中間室Bにはわずかの水圧差が生じて、 ピストン4を下方に押し下げようとする推力が生じるが、この推力が予め設定さ れたスプリング41の反力よりも小さいうちはピストン4は移動することなく、 流量は水栓本体1の開き加減によって調節される。 When the faucet body 1 is slightly opened and a small amount of water flows, as shown in FIG. 3, a slight water pressure difference occurs before and after the orifice 4a, that is, between the inflow chamber A and the intermediate chamber B, and the piston 4 is moved. A thrust force that pushes downward is generated, but as long as this thrust force is smaller than the preset reaction force of the spring 41, the piston 4 does not move, and the flow rate is adjusted by opening / closing the faucet body 1. .
【0019】 水栓本体1がさらに開かれて流量が増すと、図4に示すようにオリフィス4a の前後すなわち流入室Aと中間室Bとの水圧差が増加し、スプリング41の反力 に抗してピストン4は下方に移動する。When the water faucet body 1 is further opened to increase the flow rate, as shown in FIG. 4, the water pressure difference before and after the orifice 4 a, that is, between the inflow chamber A and the intermediate chamber B increases, and the reaction force of the spring 41 is resisted. Then, the piston 4 moves downward.
【0020】 このとき針弁4bが次第にオリフィス5aに挿入されて流量が絞られるように なり、中間室Bと流出室Cの間に水圧差が生じ、その分だけ流入室Aと中間室B の水圧差が減少してスプリング41の反力がピストン4を押戻す方向に作用し、 ついには流入室Aと中間室Bの水圧差による推力とスプリング41の反力が釣り 合う位置でピストン4は停止する。At this time, the needle valve 4b is gradually inserted into the orifice 5a so that the flow rate is reduced, and a water pressure difference is generated between the intermediate chamber B and the outflow chamber C. The water pressure difference decreases and the reaction force of the spring 41 acts in the direction to push the piston 4 back. Finally, the piston 4 moves at a position where the thrust force due to the water pressure difference between the inflow chamber A and the intermediate chamber B and the reaction force of the spring 41 are balanced. Stop.
【0021】 このときの流量はオリフィス4aの大きさとスプリング41の反力によって規 定され、なんらかの原因で給水源の水圧が上昇して流量が増加しようとすると、 ピストン4が移動して針弁4bがオリフィス5aをさらに塞ぎ、新たな位置でス プリング5の反力と釣り合い、ツマミ52によって設定された流量を維持するこ とができる。The flow rate at this time is determined by the size of the orifice 4a and the reaction force of the spring 41, and if the water pressure of the water supply source rises and the flow rate increases for some reason, the piston 4 moves and the needle valve 4b Can further block the orifice 5a, balance with the reaction force of the spring 5 at a new position, and maintain the flow rate set by the knob 52.
【0022】 設定流量を変えるにはツマミ52を回してスライダー5を上下に移動させるこ とによって行なうことができる。The set flow rate can be changed by turning the knob 52 and moving the slider 5 up and down.
【0023】 例えば、設定流量を減少させたいときには、図5に示すようにツマミ52を回 してスライダー5を上方に移動させ、ピストン4がわずかに移動したとき針弁4 bがオリフィス5aに挿入されるようにすればよい。For example, when it is desired to reduce the set flow rate, as shown in FIG. 5, the knob 52 is turned to move the slider 5 upward, and when the piston 4 slightly moves, the needle valve 4 b is inserted into the orifice 5 a. It should be done.
【0024】 以上水栓本体1との接続側に流量調整部を設けた実施例について説明したが 、別の実施例として図6に示すように止め輪42の嵌挿構造を一部変更すれば吐 出側にこれを設けることも可能であり、作用および各部位の機能は前述の実施例 と同等である。Although the embodiment in which the flow rate adjusting unit is provided on the connection side with the faucet body 1 has been described above, as another embodiment, if the fitting structure of the retaining ring 42 is partially changed as shown in FIG. It is also possible to provide this on the discharge side, and the operation and the function of each part are the same as those in the above-mentioned embodiment.
【0025】[0025]
流し台などにおいて使用目的に応じてあらかじめツマミ52を適切に設定して おけば開閉の都度水栓本体1のハンドルを調節しなくても最大流量を適切な値に 制限することができる。 If the knob 52 is appropriately set in advance in a sink or the like according to the purpose of use, the maximum flow rate can be limited to an appropriate value without adjusting the handle of the faucet body 1 each time it is opened and closed.
【0026】 その効果は特に近年その便利さ故普及しつつあるシングルレバー型の水栓にお いて著しい。The effect is particularly remarkable in the single lever type water faucet which is becoming popular due to its convenience in recent years.
【0027】 その理由は同水栓は別名ワンタッチ水栓とも言われるようにハンドルの操作ス トロークが小さく、細かい水量調節がしにくいためで、本考案の自在管を接続す れば一気に解決が可能であり、また必要に応じて流量の設定値を変えることも容 易である。The reason for this is that the faucet, which is also called a one-touch faucet, has a small operation stroke of the handle and it is difficult to finely adjust the water volume, so it is possible to solve it at once by connecting the universal pipe of the present invention. It is also easy to change the flow rate setting value if necessary.
【0028】 高層住宅の低階層など給水圧が高い場合にも流量の調節が容易になり、飛沫の 飛散がなくなり快適な水の使用が期待できるばかりでなく、水資源の浪費を防ぐ ことができる。Even when the water supply pressure is high, such as in a low-rise building of a high-rise house, the flow rate can be easily adjusted, splashes are not scattered, comfortable water can be expected, and waste of water resources can be prevented. .
【0029】 また、地域や建物の高低差による水圧の差や近隣からの水打現象などに起因す る水圧の変動にともなう不具合を最小限に抑えることも可能である。Further, it is also possible to minimize a defect caused by a difference in water pressure due to a difference in height of a region or a building and a fluctuation in water pressure due to a water hammer phenomenon from the neighborhood.
【0030】 しかも既設の配管や水栓本体に手を加える必要がなく、一般家庭の主婦にでも 簡単にかつ安価に交換できるので広く効果が期待できる。Moreover, since it is not necessary to modify the existing pipes and faucet body, even housewives in general households can easily and inexpensively replace them, and thus a wide effect can be expected.
【0031】 現実に使用されている水栓の全体の数を想定すれば、水資源浪費の防止は恒常 化しつつある大都市における水不足の不安解消や水道施設の運営に使われるエネ ルギーの節約など環境保全にも貢献できる。Assuming the total number of faucets actually used, prevention of waste of water resources is becoming more permanent, eliminating concerns over water shortages and saving energy used to operate water facilities. It can also contribute to environmental conservation.
