It consists of a valve member that faces into the continuous valve housing and an arm that swings up and down by a float.A part of the arm faces into the valve housing through a slit provided in the valve housing. A valve on the upper surface of the arm is provided with a ball tap that pushes up the valve member to close the liquid supply port, and an overflow port is provided on the wall of the liquid storage tank near a position facing the slit. A rising wall surface rising upward or diagonally upward is formed on the outside of the member support portion.

り、アームによる弁部材の給液口の閉止を解く。(Function) When the liquid in the liquid storage tank is drained by opening the valve installed at the outlet of the liquid storage tank, the float will lower as the liquid level falls, and the arm will also lower accordingly. Unblock the liquid supply port of the valve member.

き顕著に生じる。 For this reason, a portion of the liquid supplied from the liquid supply port into the liquid storage tank flows along the arm and flows out of the valve housing through the slit, resulting in the above-mentioned inconvenience. This is particularly noticeable when the valve member is slightly opened as shown by the dotted line in FIG.

タンク壁に設けたオーバフロー口を示す。 In the drawing, 1 is a liquid storage tank, 2 is a valve member 5 facing into a valve housing 4 connected to a liquid supply port 3 provided at the upper part of the liquid storage tank 1, and an arm 7 that swings up and down by a float 6. A part of the arm 7 is made to face inside the valve housing 4 through a slit 8 provided in the valve housing 4, and the valve member 5 is pushed up by the arm 7 to close the liquid supply port 3. The arm 7 constituting the ball tap 2 includes a first arm 7a whose root is pivotally supported in the liquid storage tank 1, a float 6 provided at the other end, and one end located outside the valve housing 4. The second arm 7c is pivotally supported and the other end is connected to the first arm 7a via a connecting piece 7b, and the second arm 7c faces into the valve housing 4 through a slit 8. Valve member support portion 7c on the upper surface of the second arm 7c
-1 to push up the valve member 5, and rising wall surfaces 9 rising upward or diagonally upward are formed on both sides of the support portion 7c-1. Reference numeral 10 indicates an overflow port provided in the wall of the liquid storage tank near a position facing the slit 8 provided in the valve housing 4.

The flow tries to flow out of the valve housing 4 along the upper surface of the arm 7c, but since there is a rising wall surface 9 that rises upward or diagonally upward on the upper surface of the arm 7c, the flow is obstructed by the wall surface, and the flow is blocked on both sides of the arm. flowing down from

It is possible to prevent the supplied liquid from flowing out of the valve housing from the slit along the slit, and to prevent as much as possible the inconvenience caused by the supplied liquid flowing out of the valve housing through the slit, which is seen in conventional examples. There is.
