溝１９により流量を確認できる。(Structure of the invention) In the figure, when liquid flows in the direction of arrow X,
The liquid flows from the liquid passage hole 10 in the shaft of the adapter 1 to the liquid passage space 18 around the shaft to the adapter 2. At this time, the indicator 6 is pushed to the left in the figure against the elastic force of the compression spring 7.
The movement of the indicator 6 allows the flow rate to be confirmed by a scale groove 19 provided in the transparent outer tube 4.
通液空間１８内を軸方向に流体が流れると、長
い時間すると透明外管４の内面に水垢がたまり、
内部のインジケータ６が透視しにくくなる。 When fluid flows in the axial direction within the liquid passage space 18, limescale accumulates on the inner surface of the transparent outer tube 4 over a long period of time.
The internal indicator 6 becomes difficult to see through.

ているので水漏れの心配はない。 In this state, when the wiper 5 is pushed in a direction against the flow using the knurled knob 15, the O-ring 14 at the tip comes into sliding contact with the inner surface of the transparent outer tube 4, and the transparent outer tube 4 slides against the inner surface of the transparent outer tube 4. Remove limescale adhering to the inner surface of the tube 4. When the wiper 5 moves in the axial direction of the transparent outer tube 4, the O-ring 14
, the wiper effect is exhibited, but the O-ring 14
Since its inner and outer peripheral surfaces are sealed together with the O-ring 17, there is no need to worry about water leakage.
