２を介して流出する水路に切換えるようにしている。Conventional configuration and its problems In general, there are cases where it is necessary to switch the water channel in a water faucet or the like. For example, as shown in Fig. 6, tap water from a faucet 1 is supplied to a water purifier 2, and a switching valve 3 is used to flow the tap water directly through a channel and through the water purifier 2. I am trying to switch to a waterway that does.
前記切換弁３は円柱状の弁体４をつまみ６で回転させて

より水通路の切換えを行なうようになっている。The switching valve 3 is switched by rotating a cylindrical valve body 4 with a knob 6. As shown in FIG. , said first
It has a second water passage 7 formed in a concave shape in the half circumference on the opposite side to the midway opening 6a of the passage, and further has a circumferential seal ring 8 having the entire circumference at both ends, and a midway opening 6a. A ring 9 surrounding it is attached. The valve body 4 is rotatably housed in a 7 cylinder-shaped valve casing 10, and the valve casing 10 is provided with an inlet 11 and an outlet 12. By rotating 4, the water passage can be switched.
ところで前記弁体４におけるシールリングのうち、特に
中腹開口部６ａを囲むシールリング９は弁体４の回動時

むこともあり、シール性を損うという問題があった。こ
のようなことから第９図に示すように流入口１１の口径
をシールリング９が入り込まないように小径とするとよ
いが、この場合、流量が小さくなるという問題がある。By the way, among the seal rings in the valve body 4, especially the seal ring 9 surrounding the middle opening 6a crosses the inlet 11 in the valve casing 10 when the valve body 4 rotates, and is There is a risk that it may be damaged or cut, and it may also sag within the inlet 11, which poses a problem of impairing sealing performance. For this reason, as shown in FIG. 9, it is preferable to make the diameter of the inflow port 11 small so that the seal ring 9 does not enter therein, but in this case, there is a problem that the flow rate becomes small.
発明の目的
本発明は前記従来の問題に留意し、シールリングが損傷
しなく、シール性のよい切換弁を提供することを目的と
するものである。OBJECTS OF THE INVENTION The present invention has been made in consideration of the above-mentioned conventional problems, and an object of the present invention is to provide a switching valve with good sealing performance without damaging the seal ring.
発明の構成
前記目的を達成するため、本発明は円柱状の弁体の中腹

、前記橋梁部によってシールリングの摺動を円滑にし、
シールリングが流入口によって損傷あるいは切断されな
いものである。Structure of the Invention In order to achieve the above-mentioned object, the present invention provides an opening for a passageway in the middle of a cylindrical valve body, and a seal ring surrounding the opening, and a seal ring that surrounds the opening, and a valve casing with a sealing ring that surrounds the opening. In this switching valve, the inlet is provided with a bridge section in a direction perpendicular to the axis of the valve body, and the bridge section allows smooth sliding of the seal ring,
The seal ring will not be damaged or cut by the inlet.
実施例の説明
以下本発明の一実施例を第１図〜第３図にもとづき説明
する。なお、前述の第５図〜第９図と同じ構成部材には
同符号を付してあり、その説明は省略する。DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Note that the same components as in FIGS. 5 to 9 described above are designated by the same reference numerals, and their explanations will be omitted.
本実施例の特徴とするところは弁ケーシング１゜におけ

１′は円柱状の弁体４の軸と直交する方向の橋梁部１４
を有している。なお前記橋梁部１４は第４図に示すよう
に複数であってもよい。The feature of this embodiment lies in the structure of the inlet 11' in the valve casing 1°.
1' is a bridge portion 14 in a direction perpendicular to the axis of the cylindrical valve body 4;
have. Note that there may be a plurality of bridge sections 14 as shown in FIG. 4.
ここで弁体４の中腹開口部６ａを囲むシールリング９は

いので、その流量を大きく制限することがない。Here, the seal ring 9 surrounding the middle opening 6a of the valve body 4 is prevented from sagging into the inlet 11' by the bridge portion 14 at the inlet 11' when the valve body 4 is rotated. The mouth edge of the inlet 11' will not be damaged or cut, and its lifespan will be extended, and the rotation of the valve body 4 will not be obstructed. Of course, since the opening area of the inlet 11' is not extremely small, the flow rate is not greatly restricted.
