- the projection area refers to the area of the shadow generated on the rear plane when the parallel ray is projected on the object, and in this embodiment, the projection area of the flow regulating piece 110 may be perpendicular to the moving direction of the fluid.
- the flow rate control unit having a plurality of flow control pieces having different inclination includes three flow control piece 110 and the fluid passage hole (120).
- the flow rate adjusting piece having the largest inclination with the plate 100 is referred to as the first flow rate adjusting piece 110a, and as the inclination with the plate 100 decreases, the second flow rate adjusting piece (in ascending order) 110b) and the third flow control piece 110c. That is, the larger the angle formed with the plate 100, the greater the inclination, so that the angle formed between the first flow control piece 110a and the plate 100 is ⁇ 1 , and the second flow control piece 110b and the plate 100 form an angle.
- the angle formed by the angle ⁇ 2 , the third flow control piece 110c and the plate 100 is ⁇ 3 , ⁇ 1 > ⁇ 2 > ⁇ 3 .
- first fluid through holes 120 a second fluid through holes 120 b
- third fluid through holes 120 c respectively.
- the third flow regulating piece 110c having the smallest inclination with the furnace plate 100 is greatest, and accordingly, the third flow regulating piece 110c may be tilted by the largest angle.
- the first flow regulating piece 110a having the largest inclination with the plate 100 is the smallest, the first flow regulating piece 110a may be tilted at the smallest angle.
- the inclination between the plate 100 and the plurality of flow control pieces 110 is formed differently, and all the flow control pieces 110 are sequentially narrowed according to the inclination. The same force can be prevented to close all the fluid through-hole 120 at the same time.
- the opening degree of the fluid passage hole 120 may be adjusted step by step by changing the flow rate or flow rate of the fluid flowing inside the flow path 10a, thereby improving the water-saving power by discharging the appropriate amount of the flow rate.
- the areas of the fluid through-holes 110 are all formed to be the same, for example, but the areas of the fluid through-holes 110 may be formed differently.
- the drawing shows that three flow control pieces 110 are formed as an example, but when even flow rate control pieces 110 are formed, the flow control pieces 1100 facing each other are inclined to form a plate 100. The same can be formed.
- the hydraulic pressure acting on the flow control pieces 110 opposed to each other is the same, and the closing speed is the same, so the hydraulic pressure acting on both sides of the plate 100 is the same, so that the flow rate and the hydraulic pressure are concentrated on one side of the plate 100. Can be prevented. Thereby, deformation, damage, etc. of the plate 100 can be prevented.
