    • A water saving device comprising a plate member which is sandwiched within and maintained within a joint portion of a tap water line and divides the tap water line across the line of water flow. A main body block is bolted to one side of the plate member along the axis of and positioned in the middle of tap water line. The plate and the main body block each has a plurality of water saving holes arranged circumferentially so that the number of opposing holes in the plate and the main body block which are aligned to allow water flow therethrough can be changed by relative rotation of the plate member with the main body block around bolt 13.
    • 一种节水装置,其包括夹在自来水管线的接合部分内并保持在自来水管线的接合部分内的板构件,并且将自来水管线跨过水流线划分。 主体块沿着自来水管线的轴线并定位在自来水管线的中间处被螺栓连接到板构件的一侧。 板和主体块各具有沿圆周方向布置的多个节水孔,使得能够通过板构件的相对旋转来改变对准以允许水流过的板和主体块中的相对孔的数量 主体块围绕螺栓13。
