WATER-SAVING ADJUST VALVE AND WATER-SAVING TYPE FLASH VALVE

摘要

PROBLEM TO BE SOLVED: To provide a water-saving adjust valve, automatically or simply adjusted according to the water pressure and the quantity of water, making it sufficient to bring pieces only for working to a working field, and obtaining water-saving effect without largely decreasing the water pressure.;SOLUTION: The inside diameter of a water flow passage 4 piercing an adjust frame 2 is gradually decreased in diameter from one end toward the other end to form a tapered surface 4a, and the tapered surface 4a is provided with a plurality of guide grooves 5 formed in the axial direction. An adjust valve 3 is stored in the interior of the adjust frame 2 to be positioned in the axial direction of the adjust frame 2 with the respective end parts stored in the corresponding guide grooves 5 to part the water flow passage 4 into two or more sections, and the quantity of water in the water flow passage 4 is controlled by the position of the adjust valve 3.;COPYRIGHT: (C)2005,JPO&NCIPI
