It is structure composition extremely common and important in Hydraulic Elements and system, the quality of its damping characteristic is for Hydraulic Elements and system
Important.
The damping characteristic in hydraulic damping hole is influenceed by its damping flow channel degree of mobility.In real work, hydraulic pressure work
Make medium to be contaminated especially solid particulate matter, micron-sized solid particulate matter is easily in the damping hole of small-bore long length
Go out to occur alluvial obstruction, pressure difference changes before and after causing damping hole, causes damping hole damping characteristic to fail, and further results in hydraulic pressure member
Part and Problem of System Reliability.Generally, damping hole is often directly opened on parts, small-bore long length hydraulic damping
Hole machined difficulty is big, and anti-solid particulate matter alluvial block capability is poor, not easy cleaning after obstruction, and repair and replacement economy and time into
This height.

Component is connected in damping hole matrix using detachable mounting means, and damping core assembly is by damping orifice plate, metal screen, support ring
Composition, damping conductor component count are multigroup, and multigroup damping conductor overlapped thereto is set, described damping orifice plate, metal screen, support
Ring overlaps successively from top to bottom, and the support ring of bottom therein is back-up ring, and screw thread, back-up ring are provided with the outside of described back-up ring
It is fixed in by screw thread on damping hole matrix.
Further, it is provided with edge face sealing member between described damping core assembly top and damping hole matrix.
Further, described seal uses O-ring seal.
Further, the damping hole relative position on described damping orifice plate staggers positioned at axis both sides.
Further, described metal screen damping hole correspondence position on damping orifice plate is provided with opening.
Further, described support ring has hollow duct.
Compared with prior art, the beneficial effects of the utility model are：Dashed forward by using damping core assembly-matrix pore structure
Broken conventional damper hole must depend on the form of element parts, by damping structure from isolation of components, realize hydraulic damping hole as one
Individual independent assembly and stacked group and replacing, you can damping orifice plate-metal screen-support ring element is increased and decreased according to damping size, group
Part especially metal screen can be changed according to oil contamination degree.
By traditional thin, long single damping hole is decomposed into stubby multi-stage series structure to the utility model, is hindered in liquid equivalent
On the premise of can increase damping bore dia, strengthen antiblocking ability；Easily realize processing；And segmentation filtering, it is highly resistant to
Solid particle alluvial obstruction damping hole.
