Description

本発明は、所定の設置面上に、湯・水を吐水するスパウト部と、湯・水の吐水量をそれぞれ制御する操作ハンドルとが併設された水栓装置に関する。 The present invention relates to a faucet device in which a spout unit for discharging hot water and water and an operation handle for controlling the water discharge amount of hot water and water are provided on a predetermined installation surface.

所定の設置面上に、湯・水を吐水するスパウト部と、湯・水の吐水量をそれぞれ制御する操作ハンドルとが併設された水栓装置において、スパウト部（吐水部）と操作ハンドル（バルブ部）との間に流路を形成するため、従来、銅管を水平方向に接続する方式がとられている（例えば、特許文献１参照。）。特許文献１記載の水栓装置は、バルブケースを設置面の下側から挿入し、設置面の上側から固定ネジで止める構造である。 In a faucet device in which a spout unit for discharging hot water and water and an operation handle for controlling the amount of water discharged from the hot water are provided on a predetermined installation surface, the spout unit (water discharge unit) and the operation handle (valve) Conventionally, a method of connecting copper pipes in the horizontal direction has been used (see, for example, Patent Document 1).

特許文献１記載の水栓装置の場合、バルブケースに設けられた銅管の接続部が設置面に開設されたバルブケース取付孔よりも突出している。従って、施工時、設置面の下側で部材を支える作業者と、設置面の上側で固定する作業者とが必要であり、施工が煩わしい。 In the case of the faucet device described in Patent Document 1, the connection part of the copper pipe provided in the valve case protrudes from the valve case attachment hole opened in the installation surface. Therefore, at the time of construction, an operator who supports the member below the installation surface and an operator who fixes the member above the installation surface are necessary, and the construction is troublesome.

本発明が解決しようとする課題は、煩わしい作業が不要で、施工が容易な水栓装置を提供することにある。 The problem to be solved by the present invention is to provide a faucet device that does not require cumbersome work and is easy to construct.

本発明の水栓装置は、所定の設置面に設置され操作ハンドルの回転量で吐水量を制御する流量調整バルブが収納されたバルブケースと、前記流量調整バルブによって流量調整された水を底部から導入して吐水するスパウトと、を備えた水栓装置であって、
前記スパウトは前記設置面に開設されたスパウト取付孔に当該設置面の上方から挿入固定され、
前記バルブケースは前記設置面に開設されたバルブケース取付孔に当該設置面上方から挿入固定され、
前記バルブケースの底面に並設されたバルブ流入孔、バルブ流出孔とそれぞれ連通するバルブ流入経路、バルブ流出経路を前記バルブケースに形成し、
給水源と前記バルブ流入孔とを連通するバルブ流入管と、前記バルブ流出孔と前記スパウト下部とを連通する可撓性のバルブ流出管と、を設けたことを特徴とする。 The water faucet device of the present invention is installed on a predetermined installation surface and contains a valve case in which a flow rate adjusting valve for controlling the amount of water discharged is controlled by the amount of rotation of the operation handle, and water adjusted by the flow rate adjusting valve from the bottom. A faucet device comprising a spout for introducing and discharging water,
The spout is inserted and fixed from above the installation surface into a spout mounting hole established on the installation surface,
The valve case is inserted and fixed from above the installation surface into a valve case mounting hole established on the installation surface,
A valve inflow path and a valve outflow path communicating with the valve inflow hole and the valve outflow hole, which are arranged in parallel on the bottom surface of the valve case, are formed in the valve case,
A valve inlet pipe that communicates the water supply source and the valve inlet hole, and a flexible valve outlet pipe that communicates the valve outlet hole and the spout lower part are provided.

このような構成とすれば、バルブケースを設置面の上方から取り付け固定し、可撓性を有するバルブ流出管をスパウト下部に連通させることが可能となる。このため、設置面のバルブケース取付孔にバルブケースを取り付けるときに、煩わしい作業が不要となり、施工が容易となる。 With such a configuration, the valve case can be attached and fixed from above the installation surface, and the flexible valve outflow pipe can be communicated with the lower part of the spout. For this reason, when attaching a valve case to the valve case attachment hole of an installation surface, a troublesome operation | work becomes unnecessary and construction becomes easy.

ここで、前記バルブ流出経路が前記バルブ流入経路の側面の一部を包囲するように前記バルブケースを形成すれば、設置面のバルブケース取付孔に当該設置面の上方からバルブケースを挿入固定する構造であっても、バルブ流出経路およびバルブ流入経路の流路面積を確保することができるため、充分な吐水量を確保することができる。 Here, if the valve case is formed so that the valve outflow path surrounds a part of the side surface of the valve inflow path, the valve case is inserted and fixed from above the installation surface into the valve case mounting hole of the installation surface. Even with the structure, the flow area of the valve outflow path and the valve inflow path can be ensured, so that a sufficient water discharge amount can be ensured.

一方、前記バルブ流出管の下流側に連結された継ぎ手管に当該継ぎ手管と交差する方向に並ぶ第１連結穴と、前記第１連結穴より内径の小さな第２連結穴とを設け、
前記スパウトの底部に垂下状に連結された通水管の下端部外周に流入口を開設するとともに前記流入口の上方に前記第１連結穴に嵌入する第１嵌合部を設け、前記流入口の下方に前記第２連結穴に嵌入する第２嵌合部を設け、
前記通水管の前記第１嵌合部、前記第２嵌合部をそれぞれ前記継ぎ手管の前記第１連結穴、前記第２連結穴に嵌入させることにより前記通水管と前記継ぎ手管とを連通させ、
前記第１嵌合部と前記第１連結穴との間および前記第２嵌合部と第２連結穴との間に、それぞれリング状パッキンを介在させることができる。 On the other hand, the joint pipe connected to the downstream side of the valve outlet pipe is provided with a first connection hole arranged in a direction intersecting the joint pipe, and a second connection hole having an inner diameter smaller than the first connection hole,
An inflow opening is formed on the outer periphery of the lower end of the water pipe connected in a hanging manner to the bottom of the spout, and a first fitting portion is provided above the inflow opening to be fitted into the first connection hole. A second fitting portion that is fitted into the second connection hole is provided below,
By fitting the first fitting portion and the second fitting portion of the water pipe into the first connection hole and the second connection hole of the joint pipe, respectively, the water pipe and the joint pipe are communicated with each other. ,
Ring-shaped packings can be interposed between the first fitting portion and the first connecting hole and between the second fitting portion and the second connecting hole, respectively.

このような構成とすれば、第１連結穴より内径の小さな第２連結穴に嵌入する第２嵌合部の外径は第１連結穴の内径より小さいので、通水管の第１嵌合部、第２嵌合部を継ぎ手管の第１連結穴、第２連結穴に向かって差し込むと、第２嵌合部が第１連結穴を通過した後、第２連結穴に嵌入され、同時に、第１嵌合部が第１連結穴に嵌入される。このため、第２嵌合部が第１連結穴を通過する際に互いに摺動することがなくなり、継ぎ手管の第１連結穴、第２連結穴に対する通水管の第１嵌合部、第２嵌合部の挿入力が軽減される。 With such a configuration, the outer diameter of the second fitting portion that fits into the second connecting hole having an inner diameter smaller than that of the first connecting hole is smaller than the inner diameter of the first connecting hole. When the second fitting part is inserted toward the first connection hole of the joint pipe and the second connection hole, the second fitting part is inserted into the second connection hole after passing through the first connection hole, The first fitting portion is fitted into the first connection hole. For this reason, when a 2nd fitting part passes a 1st connection hole, it does not slide mutually, the 1st fitting part of the water flow pipe with respect to the 1st connection hole of a joint pipe, and the 2nd connection hole, the 2nd The insertion force of the fitting part is reduced.

また、前記継ぎ手管と前記通水管との交差部内において前記通水管の流入口と対向する前記継ぎ手管の内周部に、前記流入口の口径より広い拡径部を設けることが望ましい。このような構成とすれば、継ぎ手管と交差して設けられた連結穴に、通水管の下端部を挿入して継ぎ手管と通水管とを連通させるとき、通水管の流入口の軸心と継ぎ手管の軸心とが完全に一致していなくても、継ぎ手管内の水は拡径部内を迂回して通水管の流入口へ流れ込むことができる。このため、継ぎ手管と通水管との交差部における正確な位置合わせが不要となり、施工が容易となる。 In addition, it is desirable to provide an enlarged portion wider than the diameter of the inlet at the inner periphery of the joint pipe facing the inlet of the water pipe in the intersection between the joint pipe and the water pipe. With such a configuration, when the lower end portion of the water pipe is inserted into the connection hole provided so as to intersect with the joint pipe and the joint pipe and the water pipe are communicated with each other, the axial center of the inlet of the water pipe Even if the axial center of the joint pipe does not completely coincide, the water in the joint pipe can bypass the enlarged diameter portion and flow into the inlet of the water pipe. This eliminates the need for accurate alignment at the intersection between the joint pipe and the water pipe, and facilitates construction.

本発明により、煩わしい作業が不要で、施工が容易な水栓装置を提供することができる。 According to the present invention, it is possible to provide a faucet device that does not require troublesome work and is easy to construct.

次に、図４に基づいて、操作ハンドル１２，１３、流量調整バルブ２，３およびバルブケース２２，２３などの構造について説明する。なお、流量調整バルブ２，３およびバルブケース２２，２３などの構造は互いに同じであるため、図１，図２中の左側に位置する操作ハンドル１２およびバルブケース２２などについて説明する。 Next, the structure of the operation handles 12, 13, the flow rate adjusting valves 2, 3 and the valve cases 22, 23 will be described with reference to FIG. Since the flow rate adjusting valves 2 and 3 and the valve cases 22 and 23 have the same structure, the operation handle 12 and the valve case 22 positioned on the left side in FIGS. 1 and 2 will be described.

図４に示すように、バルブケース２２内には、下から順に、流量調整バルブ２、スピンドル９およびスピンドルガイド８が収容されている。そして、設置面１１の上方から台座７、スペーサ６、締付けナット５、ブッシュ４、ハンドル本体１２ａが配置され、ハンドル本体１２ａの上面開口部１２ｂから下方へ挿入されたネジＮ１の下端部が、流量調整バルブ２の軸部２ｓの上端部に螺合されている。また、ハンドル本体１２ａの上面開口部１２ｂはインデックス１によって覆われている。 As shown in FIG. 4, the flow rate adjusting valve 2, the spindle 9 and the spindle guide 8 are accommodated in the valve case 22 in order from the bottom. The base 7, the spacer 6, the tightening nut 5, the bush 4, and the handle main body 12a are arranged from above the installation surface 11, and the lower end of the screw N1 inserted downward from the upper surface opening 12b of the handle main body 12a has a flow rate. The adjustment valve 2 is screwed into the upper end portion of the shaft portion 2s. The upper surface opening 12 b of the handle body 12 a is covered with the index 1.

一方、流量調整バルブ２の軸部２ｓ、スピンドル９の軸部９ｓおよびブッシュ４の外周部４ｓにはそれぞれセレーションが設けられている。また、流量調整バルブ２とスピンドルガイド８との嵌合部分、スピンドルガイド８と台座７との嵌合部分には、それぞれ六角形状の嵌合部２ｃ，８ｃが設けられている。 On the other hand, serrations are provided on the shaft portion 2 s of the flow rate adjusting valve 2, the shaft portion 9 s of the spindle 9, and the outer peripheral portion 4 s of the bush 4. Further, hexagonal fitting portions 2c and 8c are provided in the fitting portion between the flow rate adjusting valve 2 and the spindle guide 8 and the fitting portion between the spindle guide 8 and the base 7, respectively.

次に、図７〜図１３に基づいて、バルブケース２２，２３について説明する。なお、前述したように、バルブケース２２，２３の構造、機能は互いに同じであるため、以下、バルブケース２２について説明する。図７は図１に示す水栓装置を構成するバルブケースの平面図、図８は図７におけるＢ−Ｂ線断面図、図９は図１に示す水栓装置を構成するバルブケースの底面図、図１０は図８におけるＣ−Ｃ線断面図、図１１は図８におけるＤ−Ｄ線断面図、図１２は図８におけるＥ−Ｅ線断面図、図１３は図８におけるＦ−Ｆ線断面図である。 Next, the valve cases 22 and 23 will be described with reference to FIGS. As described above, since the valve cases 22 and 23 have the same structure and function, the valve case 22 will be described below. 7 is a plan view of the valve case constituting the water faucet device shown in FIG. 1, FIG. 8 is a sectional view taken along the line BB in FIG. 7, and FIG. 9 is a bottom view of the valve case constituting the water faucet device shown in FIG. 10 is a sectional view taken along the line CC in FIG. 8, FIG. 11 is a sectional view taken along the line DD in FIG. 8, FIG. 12 is a sectional view taken along the line EE in FIG. It is sectional drawing.

図７〜図１３に示すように、バルブケース２２の底面にはバルブ流入孔１５ｈおよびバルブ流出孔１６ｈが併設され、これらのバルブ流入孔１５ｈ、バルブ流出孔１６ｈとそれぞれ連通するバルブ流入経路１５、バルブ流出経路１６がバルブケース２２内に形成されている。また、バルブケース２２内には、上から順に、スピンドル収容部２２ａ、バルブ収容部２２ｂが設けられている。バルブ収容部２２ｂの底面には、バルブ流入経路１５と連通する開口部１５ａ、バルブ流出経路１６と連通する開口部１６ａが開設されている。 As shown in FIGS. 7 to 13, a valve inflow hole 15 h and a valve outflow hole 16 h are provided on the bottom surface of the valve case 22, and a valve inflow path 15 that communicates with the valve inflow hole 15 h and the valve outflow hole 16 h, respectively. A valve outflow path 16 is formed in the valve case 22. Further, in the valve case 22, a spindle accommodating portion 22a and a valve accommodating portion 22b are provided in order from the top. An opening 15a that communicates with the valve inflow path 15 and an opening 16a that communicates with the valve outflow path 16 are formed on the bottom surface of the valve housing portion 22b.

図５に示す操作ハンドル１２を開操作すると、流量調整バルブ２が回転して開口部１５ａ，１６ａとが連通し、給湯源（図示せず）とバルブ流入孔１５ｈとを連通するバルブ流入管２５からバルブ流入孔１５ｈおよびバルブ流入経路１５を経由して流れ込んだ湯が流量調整バルブ２内でＵターンし、バルブ流出経路１６からバルブ流出孔１６ｈを経て流れ出す。バルブ流出孔１６ｈから流出した湯は可撓性のバルブ流出管２６を通過し、継ぎ手管２１の連結部２１ｈを経由して通水管２０の下端部へ流れ込み、スパウト１４の吐水口１４ａから吐水される。 When the operation handle 12 shown in FIG. 5 is opened, the flow rate adjusting valve 2 rotates to communicate with the openings 15a and 16a, and a valve inlet pipe 25 that communicates a hot water supply source (not shown) with the valve inlet hole 15h. The hot water flowing in through the valve inflow hole 15h and the valve inflow path 15 makes a U-turn in the flow rate adjusting valve 2 and flows out of the valve outflow path 16 through the valve outflow hole 16h. Hot water flowing out from the valve outlet hole 16h passes through the flexible valve outlet pipe 26, flows into the lower end portion of the water pipe 20 through the connecting portion 21h of the joint pipe 21, and is discharged from the water outlet 14a of the spout 14. The

このように、操作ハンドル１２を開操作することにより、スパウト１４の吐水口１４ａから湯を吐水させることができ、そのときの吐水量は操作ハンドル１２の回転角度に応じて増減するように設定されている。また、バルブケース２３はバルブケース２２と同じ構造であるため、図１，図２中の右側に位置する操作ハンドル１３を開操作すると、スパウト１４の吐水口１４ａから水を吐水させることができ、そのときの吐水量は操作ハンドル１３の回転角度に応じて増減するように設定されている。 Thus, by opening the operation handle 12, hot water can be discharged from the spout 14a of the spout 14, and the amount of water discharged at that time is set to increase or decrease according to the rotation angle of the operation handle 12. ing. Moreover, since the valve case 23 has the same structure as the valve case 22, when the operation handle 13 located on the right side in FIGS. 1 and 2 is opened, water can be discharged from the water outlet 14a of the spout 14, The water discharge amount at that time is set so as to increase or decrease according to the rotation angle of the operation handle 13.

即ち、図１，図２に示す左側の操作ハンドル１２を開操作するとスパウト１４から湯が吐水し、右側の操作ハンドル１３を開操作するとスパウト１４から水が吐水する。そして、操作ハンドル１２，１３を両方とも開操作すると、継ぎ手管２１と通水管２０との連結部分において湯と水とが混合され、スパウト１４から吐水される。このとき、スパウト１４の吐水口１４ａから吐水される混合水の温度は、操作ハンドル１２，１３の開度によって調節することができる。 That is, when the left operation handle 12 shown in FIGS. 1 and 2 is opened, hot water is spouted from the spout 14, and when the right operation handle 13 is opened, water is spouted from the spout 14. When both the operation handles 12 and 13 are opened, hot water and water are mixed at the connection portion between the joint pipe 21 and the water flow pipe 20 and discharged from the spout 14. At this time, the temperature of the mixed water discharged from the spout 14 a of the spout 14 can be adjusted by the opening degree of the operation handles 12 and 13.

本実施形態の水栓装置１０においては、バルブケース２２，２３を設置面１１の上方から挿入し、ナットＮ２を螺合することによって固定し、可撓性を有するバルブ流出管２６をスパウト１４下部に連通させることができる。このため、設置面１１に開設されたバルブケース取付孔２２ｈ，２３ｈにバルブケース２２，２３を取り付けるとき、バルブケース２２，２３と、バルブケース取付孔２２ｈ，２３ｈとの鉛直軸Ｙ（図２参照）周りの位置合わせが不要となる。また、設置面１１の下側で部材を支え、設置面１１の上側で固定するという従来の煩わしい作業が不要となるため、施工が容易となる。 In the faucet device 10 of the present embodiment, the valve cases 22 and 23 are inserted from above the installation surface 11 and fixed by screwing the nut N2, and the flexible valve outflow pipe 26 is attached to the lower part of the spout 14. Can be communicated to. Therefore, when the valve cases 22 and 23 are attached to the valve case attachment holes 22h and 23h opened on the installation surface 11, the vertical axis Y between the valve cases 22 and 23 and the valve case attachment holes 22h and 23h (see FIG. 2). ) Positioning around is not necessary. Moreover, since the conventional troublesome operation | work which supports a member under the installation surface 11 and fixes on the upper side of the installation surface 11 becomes unnecessary, construction becomes easy.

また、水栓装置１０においては、図１１〜図１３に示すように、バルブ流出経路１６がバルブ流入経路１５の側面の一部を包囲するようにバルブケース２２，２３が形成されている。従って、設置面１１のバルブケース取付孔２２ｈ，２３ｈに当該設置面１１の上方からバルブケース２２，２３を挿入固定する構造であっても、バルブ流出経路１６およびバルブ流入経路１５の流路面積を確保することが可能であり、これによって必要な吐水量を確保することができる。 Further, in the faucet device 10, valve cases 22 and 23 are formed so that the valve outflow path 16 surrounds a part of the side surface of the valve inflow path 15, as shown in FIGS. 11 to 13. Therefore, even if the valve cases 22 and 23 are inserted and fixed to the valve case mounting holes 22h and 23h of the installation surface 11 from above the installation surface 11, the flow area of the valve outflow path 16 and the valve inflow path 15 is reduced. It is possible to ensure the required amount of water discharge.

次に、図５および図１４〜図１７に基づいて、通水管２０と継ぎ手管２１との連結構造について説明する。図１４は図５の一部拡大図、図１５は図１４に示す継ぎ手管の断面図、図１６は図１５におけるＧ−Ｇ線断面図、図１７は図１４に示す通水管の一部省略側面図である。 Next, based on FIG. 5 and FIGS. 14-17, the connection structure of the water flow pipe 20 and the joint pipe | tube 21 is demonstrated. 14 is a partially enlarged view of FIG. 5, FIG. 15 is a cross-sectional view of the joint pipe shown in FIG. 14, FIG. 16 is a cross-sectional view taken along the line GG in FIG. It is a side view.

Yes. The inner diameter 21er of the second connection hole 21e is smaller than the inner diameter 21dr of the first connection hole 21d. In addition, as shown in FIGS. 5, 14, and 17, inflow ports 20c and 20h are formed on the outer periphery of the lower end portion of the water pipe 20 connected to the bottom of the spout 14 in a hanging manner, and above the inflow ports 20c and 20h. 15 is provided with a first fitting portion 20t that fits into the first connecting hole 21d shown in FIG. 15, and a second fitting portion 20u that fits into the second connecting hole 21e is provided below the inflow ports 20c and 20h. Yes. The outer diameter 20ur of the second fitting part 20u is formed smaller than the outer diameter 20tr of the first fitting part 20t. Further, the inner diameter 21dr of the first connecting hole 21d and the outer diameter 20tr of the first fitting portion 20t are substantially equal, and the inner diameter 21er of the second connecting hole 21e and the outer diameter 20ur of the second fitting portion 20u are substantially equal. It is equivalent.

図１４に示すように、通水管２０の第１嵌合部２０ｔ、第２嵌合部２０ｕをそれぞれ継ぎ手管２１の第１連結穴２１ｄ、第２連結穴２１ｅにそれぞれ嵌入させることにより通水管２０と継ぎ手管２１とが連通されている。そして、継ぎ手管２１の第２連結穴２１ｅの下方に突出する通水管２０の下端部２０ｖにナットＮ３を螺着することにより、継ぎ手管２１と通水管２０とが固定されている。また、第１嵌合部２０ｔと第１連結穴２１ｄとの間および第２嵌合部２０ｕと第２連結穴２１ｅとの間にそれぞれリング状パッキン２４ａ，２４ｂを介在させている。リング状パッキン２４ａは、通水管２０の第１嵌合部２０ｔの外周に設けられた周溝２０ｔｍに嵌入され、リング状パッキン２４ｂは、第２嵌合部２０ｕの外周に設けられた周溝２０ｕｍに嵌入されている。これらのリング状パッキン２４ａ，２４ｂは、通水管２０と継ぎ手管２１との嵌合部の水密性を保つために設けられているが、リング状パッキン２４ｂの外径はリング状パッキン２４ａの外径より小である。 As shown in FIG. 14, the first and second fitting portions 20 t and 20 u of the water pipe 20 are fitted into the first connection hole 21 d and the second connection hole 21 e of the joint pipe 21, respectively. And the joint pipe 21 are communicated with each other. And the joint pipe | tube 21 and the water flow pipe 20 are being fixed by screwing nut N3 to the lower end part 20v of the water flow pipe 20 which protrudes below the 2nd connection hole 21e of the joint pipe | tube 21. As shown in FIG. Further, ring-shaped packings 24a and 24b are interposed between the first fitting portion 20t and the first connecting hole 21d and between the second fitting portion 20u and the second connecting hole 21e, respectively. The ring-shaped packing 24a is fitted into a circumferential groove 20tm provided on the outer periphery of the first fitting portion 20t of the water pipe 20, and the ring-shaped packing 24b is a circumferential groove 20um provided on the outer periphery of the second fitting portion 20u. Is inserted. These ring-shaped packings 24a and 24b are provided to maintain the watertightness of the fitting portion between the water flow pipe 20 and the joint pipe 21, but the outer diameter of the ring-shaped packing 24b is the outer diameter of the ring-shaped packing 24a. Is smaller.

図１，図２で示した操作ハンドル１２，１３を開操作することにより、二つのバルブ流出管２６からそれぞれ継ぎ手管２１の連結部２１ｈ，２１ｃへ流入した湯、水は、通水管２０の下端部分の流入口２０ｃ，２０ｈを通過して通水管２０内に流入し、通水管２０内を上昇しながら混合され、設置面１１の上方に設置されたスパウト１４の吐水口１４ａから吐水される。 By opening the operation handles 12 and 13 shown in FIGS. 1 and 2, hot water and water flowing into the connecting portions 21 h and 21 c of the joint pipe 21 from the two valve outflow pipes 26 are respectively at the lower end of the water flow pipe 20. The water passes through the partial inlets 20 c and 20 h, flows into the water pipe 20, is mixed while rising in the water pipe 20, and is discharged from the water outlet 14 a of the spout 14 installed above the installation surface 11.

水栓装置１０においては、第１連結穴２１ｄの内径２１ｄｒより小さな内径２１ｅｒの第２連結穴２１ｅに嵌入される第２嵌合部２０ｕの外径２０ｕｒは、第１連結穴２１ｄの内径２１ｄｒより小さく形成されている。従って、通水管２０の第１嵌合部２０ｔ、第２嵌合部２０ｕを継ぎ手管２１の第１連結穴２１ｄ、第２連結穴２１ｅに向かって差し込むと、第２嵌合部２０ｕは、第１連結穴２１ｄを通過した後、第２連結穴２１ｅに嵌入されると同時に、第１嵌合部２０ｔが第１連結穴２１ｄに嵌入される。このため、第２嵌合部２０ｕが第１連結穴２１ｄを通過する際に互いに摺動することがなく、継ぎ手管２１の第１連結穴２１ｄ、第２連結穴２１ｅに対する通水管２０の第１嵌合部２０ｔ、第２嵌合部２０ｕの挿入力を軽減することができる。 In the faucet device 10, the outer diameter 20ur of the second fitting portion 20u fitted into the second connecting hole 21e having the inner diameter 21er smaller than the inner diameter 21dr of the first connecting hole 21d is larger than the inner diameter 21dr of the first connecting hole 21d. It is formed small. Therefore, when the first fitting portion 20t and the second fitting portion 20u of the water flow pipe 20 are inserted toward the first connecting hole 21d and the second connecting hole 21e of the joint pipe 21, the second fitting portion 20u is After passing through the first connecting hole 21d, the first fitting portion 20t is inserted into the first connecting hole 21d at the same time as being inserted into the second connecting hole 21e. For this reason, when the 2nd fitting part 20u passes the 1st connection hole 21d, it does not slide mutually, but the 1st connection hole 21d of the joint pipe 21 and the 1st of the water flow pipe 20 with respect to the 2nd connection hole 21e The insertion force of the fitting part 20t and the second fitting part 20u can be reduced.

一方、図５に示すバルブケース２２，２３は、設置面１１に対して鉛直軸Ｙ（図２参照）を中心に回動可能であるため、流量調整バルブ２，３に操作ハンドル１２，１３を取り付けるときに、バルブケース２２，２３を回転させることにより、操作ハンドル１２，１３の取付位置を確定することができる。このため、バルブケース２２，２３を厳格に位置決めする必要が無く、施工性が良好である。また、図２，図５で示したように、設置面１１に開設されたバルブケース取付孔２２ｈ，２３ｈにバルブケース２２，２３を取り付けるとき、設置面１１の下側で部材を支え、設置面１１の上側で固定するという従来の煩わしい作業が不要となるため、施工が容易となる。 On the other hand, since the valve cases 22 and 23 shown in FIG. 5 are rotatable about the vertical axis Y (see FIG. 2) with respect to the installation surface 11, the operation handles 12 and 13 are attached to the flow rate adjusting valves 2 and 3, respectively. At the time of attachment, the attachment positions of the operation handles 12 and 13 can be determined by rotating the valve cases 22 and 23. For this reason, it is not necessary to position valve cases 22 and 23 strictly, and workability is good. As shown in FIGS. 2 and 5, when the valve cases 22 and 23 are installed in the valve case mounting holes 22 h and 23 h opened on the installation surface 11, the members are supported on the lower side of the installation surface 11 to support the members. Since the conventional troublesome work of fixing on the upper side of 11 becomes unnecessary, the construction becomes easy.

また、図１４〜図１６に示すように、継ぎ手管２１と通水管２０との交差部内においては、通水管２０の流入口２０ｃ，２０ｈと対向する継ぎ手管２１の内周部に、継ぎ手管２１の内径２１ｒおよび流入口２０ｃ，２０ｈの口径２０ｒより広い拡径部２１ｗを設けている。従って、継ぎ手管２１に開設された第１連結穴２１ｄおよび第２連結穴２１ｅに、通水管２０の第１嵌合部２０ｔおよび第２嵌合部２０ｕを挿入して、継ぎ手管２１と通水管２０とを交差状に連通させるとき、通水管２０の流入口２０ｃ，２０ｈの軸心と継ぎ手管２１の軸心とが完全に一致していなくても、継ぎ手管２１内の水は拡径部２１ｗ内を迂回して通水管２０の流入口２０ｃ，２０ｈへ流れ込むことができる。このため、継ぎ手管２１と通水管２０との交差部（連通部）における正確な位置合わせが不要であり、施工を容易化することができる。 14-16, in the intersection part of the joint pipe 21 and the water flow pipe 20, the joint pipe 21 is formed in the inner peripheral part of the joint pipe 21 facing the inflow ports 20c and 20h of the water flow pipe 20. An enlarged diameter portion 21w wider than the inner diameter 21r and the diameter 20r of the inflow ports 20c and 20h is provided. Accordingly, the first fitting portion 20t and the second fitting portion 20u of the water flow pipe 20 are inserted into the first connection hole 21d and the second connection hole 21e opened in the joint pipe 21, so that the joint pipe 21 and the water flow pipe are connected. 20 is communicated in a crossing manner, the water in the joint pipe 21 is expanded even if the axis of the inlets 20c and 20h of the water pipe 20 and the axis of the joint pipe 21 do not completely coincide with each other. It can flow into the inflow ports 20c and 20h of the water pipe 20 by bypassing the inside of 21w. For this reason, the exact position alignment in the crossing part (communication part) of the joint pipe 21 and the water flow pipe 20 is unnecessary, and construction can be facilitated.
