a valve chamber 13 provided at a branch of the second outflow path 11.12;
From the valve chamber 13, the first. A first valve seat 14, a second valve seat 15, each provided at an opening facing the second outflow passage 11, 12, and constituted by a rubber sheet packing, and a ball 16 provided within the valve chamber 13, are used for switching. The selector switch 17 is composed of a first switch. The second switching button 18°19 and the first switching button 18, 19, respectively. the second biasing spring 20°21, the first biasing spring 20°21;
It consists of levers 22 and 23 for moving the second ball.

る。In the above configuration, when the ball 16 is in contact with the first valve seat 14, the fluid flowing in from the inflow path 1o flows out from the second outflow path 12, but the static pressure of the fluid at that time is applied to the ball 16. The first valve seat 14 is pressed against the first valve seat 14, and the first outflow path 11 is completely closed. On the other hand, in order to switch the fluid outflow path to the first outflow path 11, when the first switching button 18 is pressed, the first ball moving lever 22 moves the ball 16 away from the first valve seat 14. , to the second valve seat 15, at which time the ball 16 is forced by the static pressure of the fluid,
The second valve seat 15 is abutted, the second outflow path 12 is completely closed, and the fluid flows out from the first outflow path 11.

The levers 22 and 23 for moving the ball convert it into left and right movement, and the first . Since force is applied in a direction that is less affected by fluid pressure (perpendicular to the flow in a flowing state) when the second valve seat moves from the state in which it is in contact with the second valve seat 14°15, the operation feeling is improved. It is lightweight, and switching operations do not become a burden due to the influence of water pressure. Furthermore, the configuration is simple and maintenance is easy.
発明の効果
以上のように本発明の三方切替弁によれば次の効果が得
られる。Effects of the Invention As described above, the three-way switching valve of the present invention provides the following effects.
（１）切替スイッチによるスイッチ操作で切替える構成
のため、操作が軽快で扱い易く、緊急時の切替えもワン
タッチで瞬間的に可能となる。(1) Since the switch is configured to be switched by a switch operation, the operation is light and easy to handle, and switching in an emergency can be done instantaneously with a single touch.
（２）流入路から流出路に至る弁室内にはボールのみが
存在するが、そのボールは開成側の流出路の弁座に当接
するのみで、他方の流出路への流れには、全く影響しな
い構成であるため切替弁としての圧力損失は極めて少な
い。(2) There is only a ball in the valve chamber leading from the inflow path to the outflow path, but the ball only contacts the valve seat of the opening side outflow path and has no effect on the flow to the other outflow path. The pressure loss as a switching valve is extremely small.
（３）構成が単純でメンテナンスが容易である。(3) The configuration is simple and maintenance is easy.
