Abstract
The invention provides a high-pressure-difference adjusting valve sleeve. The high-pressure-difference adjusting valve sleeve comprises at least one multilayered lamination unit, wherein each multilayered lamination unit comprises annular bottom plates (1), at least two annular pressure reducing plates I (2) and an annular pressure reducing plate II (3); the annular bottom plates (1) are sequentially stacked; a rectangular through hole (4) is formed in each annular pressure reducing plate I (2); a U-shaped through hole (5) is formed in the annular pressure reducing plate II (3); the annular pressure reducing plates (2) and the annular pressure reducing plate II (3) are arranged alternately; and the rectangular through holes (4) are connected with the U-shaped through hole (5). The high-pressure-difference adjusting valve sleeve has the advantages that the pressure reducing sleeve consists of the multilayered lamination units, the total thickness of a single layer of each multilayered lamination unit is consistent, and the machining process is simple; and the multilayered lamination units are stacked in a staggered manner so as to form a three-dimensional labyrinth groove flowing channel, the number of corners is large, and the pressure reducing capability of the high-pressure-difference adjusting valve sleeve is obviously higher than that of a sleeve of which the size is the same with the high-pressure-difference adjusting valve sleeve.
Description
Affiliated technical field
The present invention relates to a kind of high-differential-pressure regulating valve sleeve, particularly a kind of step-down sleeve of the formed stereo labyrinth concentrated flow road being formed by multi-layer stacks.
Background technique
Traditional sleeve only has one deck to form, and the quantity of turning round is few, and antihypertensive effect is poor, and the sleeve of maze trough runner is all non-penetrating on thickness direction, and processing technology is complicated, and groove width, groove depth be difficult for guaranteeing, work efficiency is low, and processing cost is high.
Summary of the invention
For overcoming the above-mentioned defect of existing high-differential-pressure regulating valve sleeve, the invention provides a kind of step-down sleeve being formed by multi-layer stacks, its individual layer lamination connects on through thickness, processing technology is simple, and the staggered stack of multi-layer stacks can form stereo labyrinth concentrated flow road, the quantity of turning round is many, unidimensional sleeve, and step-down ability obviously strengthens.
The technological scheme that the present invention solves its technical problem employing is a kind of high-differential-pressure regulating valve sleeve, comprise at least one multi-layer stacks unit, described multi-layer stacks unit comprises annular bottom plate (1) and at least two annular decompression board I (2) and the annular decompression board II (3) stacking gradually, in annular decompression board I (2), have rectangular through-hole (4), in annular decompression board II (3), have U-shaped through hole (5), two annular decompression boards (2), (3) are layout alternately, and rectangular through-hole (4) is interconnected with U-shaped through hole (5).
Rectangular through-hole (4) is distributed in internal-and external diameter place and the intermediate portion of annular decompression board I (2).
U-shaped through hole (5) is distributed between the internal diameter and external diameter of annular decompression board II (3).
The invention has the beneficial effects as follows the step-down sleeve that adopts multi-layer stacks to form, its individual layer lamination connects on through thickness, and processing technology is simple, with traditional just rushing, cut, can complete, and quality is good, and work efficiency is high, has saved processing cost; And the stereo labyrinth concentrated flow road that the staggered stack of multi-layer stacks forms, the quantity of turning round is many, unidimensional sleeve, step-down ability obviously strengthens.
