Description

Technical Field

[0001] This utility model relates to the technical field of discs, and in particular to three-dimensional maze discs. Background Technology

[0002] High-pressure differential pressure regulating valves, such as the fluctuating high-pressure differential pressure regulating valve disclosed in utility model patent CN214222043U and the straight-through high-pressure differential pressure regulating valve disclosed in utility model patent CN210106695U, use discs as key components. These discs feature low noise, cavitation resistance, and the ability to withstand high pressure differentials. The mainstream labyrinth-type discs are formed by using a specialized molding method to create numerous channels, each capable of carrying a certain amount of medium. A series of right-angle bends within the channels provide resistance to the medium. The valve cage composed of discs effectively reduces cavitation, vibration, and noise, thus ensuring the valve's normal and reliable operation over a longer period. There is also an improved type of labyrinth disc, where opposing grooves are formed within the labyrinth, known as opposing-type discs. Opposing-type discs have several independent grooves machined on a metal disc. The medium flowing through these grooves experiences multiple head-on collisions and deflections, continuously consuming energy and achieving layer-by-layer pressure reduction while simultaneously controlling the flow velocity.

[0003] However, regardless of whether it is a labyrinth disk or a counter-rotating labyrinth disk, all flows are restricted to radial flow within a single disk, making axial flow difficult. This results in a low throttling stage and poor practicality. Therefore, there is an urgent need for a three-dimensional labyrinth disk to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a three-dimensional labyrinth disc that improves the practicality of the three-dimensional labyrinth disc by using a flow guiding structure to perform multi-stage throttling on the medium flowing through it.

[0006] The fixing structure binds the flow guiding structure, and the flow guiding structure guides the medium.

[0007] The practicality of the three-dimensional labyrinth disc is improved by using a flow-guiding structure to throttle the medium flowing through it in multiple stages.

[0008] Preferably, the flow guiding structure is composed of multiple sets of flow guiding components;

[0009] The flow guiding component consists of multiple sets of flow guiding units;

[0010] The flow guiding unit consists of two sets of disks with their front surfaces touching. The medium flows between the two sets of disks, and the medium is throttled in multiple stages by the two sets of disks, thereby improving the practicality of the three-dimensional maze disk.

[0012] Preferably, the annular groove group on the disk consists of annular groove one, annular groove two, and annular groove three, and the connecting groove group on the disk consists of connecting groove one, connecting groove two, connecting groove three, and connecting groove four; the medium passes through connecting groove one into annular groove one, then passes through connecting groove two into annular groove two, and then the medium in annular groove two passes through connecting groove three into annular groove three, and then is discharged through connecting groove four, realizing multi-stage throttling, thereby improving the practicality of the three-dimensional maze disk.

[0013] Preferably, the disk is provided with multiple sets of positioning holes; this facilitates maintaining the accurate position of the disk during assembly, thereby improving the practicality of the three-dimensional maze disk.
