Description
Technical field
The utility model is related to piston valve technical field, and piston valve point is obtained more particularly, to one kind reduction high-speed damping force value
Assembly.
Background technology
Traditional hydraulic buffer, it damps force value and increased with the increase of speed.This is to close for low speed point
Reason.It can be said for high speed point, often bring detrimental effect.This is primarily due to, when shock absorber, which is operated in, to be put at a high speed, its
Damp force value increase too many, cause fluid pressure in shock absorber excessive, oil sealing holds the impact that can't stand highly pressurised liquid, shock absorber oil
It will be sprayed at oil sealing, cause defective shock absorber, lose set function.Damping force value during high speed how is reduced, is vibration damping
The great difficult problem that device manufacturing enterprise faces.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide a kind of rational in infrastructure, drop
The damping force value of low high speed piston point, makes shock absorber have good vibration-damping function, is not in the piston valve for leaking phenomenon at a high speed
Sub-unit.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
The technical program reduces the piston valve sub-unit of high-speed damping force value, including piston valve sub-unit to be a kind of；It is described
Upper cover of piston rod fills piston in piston valve sub-unit；Piston is provided with recovery hole；Piston nose is provided with up concave type cylinder step；
On cylinder step successively to be externally provided with rebuilt valve throttle valve plate, restore Valve seal and restore valve leaf；Under the recovery valve leaf
End is provided with multigroup recovery valve gasket；Rebuilt valve throttle valve plate, recovery Valve seal, recovery valve leaf and recovery valve gasket, which pass through, to be installed
Recovery valve guard and recovery valve nut in piston rod front end fix encapsulation.
Compared with prior art, the beneficial effects of the utility model are：The present apparatus is rational in infrastructure, reduction high speed piston point
Force value is damped, makes shock absorber that there is good vibration-damping function, is not in leak phenomenon at a high speed.Rebuilt valve throttle valve plate, rebuilt valve
Packing ring and recovery valve leaf are all on the up concave type cylinder step of piston nose, and the through-flow cylinder that formed of liquid now is led to
Gap is flowed, it is more much bigger than traditional conical flow area, so that the damping force value of point at a high speed greatly reduces, make what is put at a high speed
Force value amplification very little is damped, even without growth.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is main structure diagram of the present utility model.
Marked in figure：Piston rod 1, upper piston set 2, recovery hole 3, rebuilt valve throttle valve plate 4, recovery Valve seal 5, recovery
Valve leaf 6, recovery valve gasket 7, recovery valve guard 8, recovery valve nut 9, circulation valve guard 10, circulation valve gasket 11, flowing valve
Valve block 12, opening 13 and piston ring 14.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
Embodiment 1, as shown in fig. 1, the utility model reduce the piston valve sub-unit of high-speed damping force value, bag to be a kind of
Include piston valve sub-unit；Piston set 2 on piston rod 1 in the piston valve sub-unit；Piston 2 is provided with recovery hole 3；Piston 2
Front end is provided with up concave type cylinder step；Successively to being externally provided with rebuilt valve throttle valve plate 4, restore Valve seal 5 and on cylinder step
Restore valve leaf 6；Recovery valve leaf 6 lower end is provided with multigroup recovery valve gasket 7；Rebuilt valve throttle valve plate 4, recovery Valve seal
5th, restore valve leaf 6 and restore valve gasket 7 and fixed by the recovery valve guard 8 installed in the front end of piston rod 1 and recovery valve nut 9
Encapsulation.
Operation principle：Restored when shock absorber is in（Stretching）During state, shock absorber fluid acts on recovery by restoring hole 3
On valve throttle valve plate 4.When shock absorber is operated in low speed point, fluid can be realized by the through-flow groove of rebuilt valve throttle valve plate 4
The flowing of liquid；With the increase of speed, the pressure for acting on rebuilt valve throttle valve plate 4 also accordingly increases, and fluid pressure will
Compression recovery valve leaf 6, so as to increase the gap between piston 2 and rebuilt valve throttle valve plate 4, increases flow area, realizes liquid
Body it is through-flow.When shock absorber, which is run to, to be put at a high speed, the powerful pressure of liquid makes recovery valve leaf 6 fully be compressed, so as to be
Liquid flowing provides larger through-flow gap, and rebuilt valve throttle valve plate 4, recovery Valve seal 5 and recovery valve leaf 6 are all installed in addition
On the up concave type cylinder step of the front end of piston 2, the through-flow cylindrical through-flow gap of formation of liquid now is more logical than traditional cone
Flow area is much bigger, so that the damping force value of point at a high speed greatly reduces, makes the damping force value amplification very little put at a high speed, even
Do not increase.
Up concave type cylindrical stage is set in the front end of piston 2, enough deformation spaces are provided to restore valve leaf 6.Rebuilt valve
Packing ring 5 has higher rigidity, can be sufficiently transferred to restore on valve leaf 6 by the pressure of liquid.Restore 6 butterflies of valve leaf
Shape, using the deformation of reed, larger space is provided for liquid flowing., can be to restoring valve leaf 6 by restoring valve gasket 7
Deformation space is finely adjusted, and adjusts the flow area of liquid.The quantity of valve gasket 7 is restored in increase, and the deformation for restoring valve leaf 6 is empty
Between increase, it is on the contrary then reduce.The progress axial limiting of valve leaf 6 is restored by restoring 8 pairs of valve guard.Rational piston valve sub-unit
Structure, in low speed, it damps force value and increased with the increase of speed；It is several and in high speed, it damps force value amplification very little
Do not increase, can make shock absorber that there is good vibration-damping function, without there is the phenomenon of leakage at a high speed.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
