Description
Technical field
The utility model relates to a kind of multi-chamber damping hole precursor overflow valves.
Background technique
The application of precursor overflow valve is very extensive, and primary structure is mostly that spool, spring and damping hole are set in valve body, is passed through
Damping hole flows into oil pocket, arrives return port after circulation, this structure has applied the long period, and defect therein shows gradually,
In damping hole be frequently occluded, the oil pressure flowed in and out in damping hole is unstable, causes equipment life short, well damage.
Summary of the invention
The purpose of this utility model is in view of the deficienciess of the prior art, the guidance through this profession teacher, applicant grind
It is excessive to issue a kind of a kind of multi-chamber damping hole guide that the oil pressure for preventing from flowing in and out in damping hole plug and damping hole is stable
Flow valve.
Technical solution: including pedestal, it is characterized in that: in the horizontally arranged oil inlet of the pedestal, oil inlet along
Pedestal extends upwardly into fuel tank, and the first spool is arranged in fuel tank, and the first spool passes through the axially symmetric damping hole that two sides are arranged in
The first spring cavity in the first spool is penetrated through, spring leading truck is arranged in the top of the first spring cavity；In the first spring cavity
Flowline is arranged in top, and flowline penetrates through the top of the second spool, then is penetrated through by Quadratic Damping hole and second spring cavity, the
Gland is arranged in the top surface of corresponding spring at the top of two spring cavitys, and the fuel-displaced pipe end below Quadratic Damping hole, pressure are withstood at the top of gland
Groove is arranged in hd top face, and groove and the setting rotation hand wheel bar for extending fuel tank are affiliated to cooperation, rotation hand wheel bar and the second spool
It is threadedly coupled, the second spool bottom penetrates through the oil outlet in pedestal, and the damping hole and Quadratic Damping hole are by multiple apertures
The macropore rearranged.
The big lumen pore that the damping hole and Quadratic Damping hole is rearranged by multiple small rectangular cavities.
The utility model has the advantages that this technology is by the big lumen pore damping hole that is rearranged by multiple small rectangular cavities, can efficiency solve it is stifled
Plug problem, and oil pressure can be dispersed by multiple small rectangular cavities, it solves the problems, such as that the oil pressure flowed in and out in damping hole is unstable, makes
Service life of equipment greatly improves.
Detailed description of the invention: attached drawing 1 is the present embodiment structural schematic diagram.
Specific embodiment: referring to attached drawing 1, the present embodiment mainly includes pedestal 1, is set in the horizontal direction of the pedestal 1
Oil inlet 2 is set, oil inlet 2 extends upwardly into fuel tank 4 along pedestal 1, the first spool 5 is arranged in fuel tank 4, the first spool 5 passes through
The first spring cavity 7 in the first spool 5 of perforation of axially symmetric damping hole 6 of two sides, the top of the first spring cavity 7 are set
The leading truck 9 of spring 8 is set；Flowline 10 is set on 7 top of the first spring cavity, flowline 10 penetrates through the top of the second spool 11
Portion, then penetrated through by Quadratic Damping hole 13 and second spring cavity 14, the top surface that spring is corresponded at the top of second spring cavity 14 is set
Gland 12 is set, 10 end of flowline below Quadratic Damping hole 13 is withstood at the top of gland 12, groove 17, groove is arranged in 12 top surface of gland
17 are affiliated to cooperation with 3 bar 16 of rotation hand wheel for extending the setting of fuel tank 4, and rotation hand wheel bar 16 is threadedly coupled with the second spool 11,
Second spool, 11 bottom penetrates through the oil outlet 15 in pedestal 1, and the damping hole 6 and Quadratic Damping hole 13 are by multiple small rectangles
The big lumen pore that chamber rearranges.
Working principle: when the work of multi-chamber damping hole precursor overflow valve, oil enters fuel tank 4 through oil inlet 2, then through first
Two symmetrical damping holes 6 on spool 5 enter spring cavity 7, then enter 11 top of the second spool through flowline 10, through secondary
Damping hole 13 opens downwards gland 2, enters second spring cavity 14 afterwards, then through going out in 11 bottom of the second spool perforation pedestal 1
Hydraulic fluid port 15 flows into recycling bins, enters to need closing outflow valve body, and groove and rotation hand wheel bar are affiliated to cooperation by rotation rotation hand wheel, upwards
Rotation is closed flowline by gland 12.
For this device through many experiments, the multiple small rectangular cavities of reason can disperse oil pressure, flow in and out in solution damping hole
The unstable problem of oil pressure, greatly improves service life of equipment.
