Abstract
The utility model relates to a shock-damper piston valve adopting the new structure of a rebound and throttling valve plate. The utility model comprises a piston (1), a throttling valve leaf-spring (3) arranged on the upper end face of the piston (1), rebound and throttling valve plates (2) successively arranged at the inner side of the lower end face of the piston (1), a rebound valve plate (5) and a rebound spring seat (4). The utility model is characterized in that certain throttling grooves (6) are arranged on the rebound and throttling valve plates (2); the throttling grooves (6) include kidney grooves (61) and notching grooves (62) linking to the notching grooves. The utility model is characterized in sound throttling capacity, stable heat exchange, stable performance and long service life.
Description
Technical field
The utility model relates to the vibration damper field, is a kind of good product performance specifically, the application of long service life restore the shock absorber piston valve of throttle valve plate new structure.
Background technique
At present, throttling groove on the recovery throttle valve plate that uses on traditional shock absorber piston valve all is that restriction is identical with throttleng surface, the fluid that flows on the piston rod just directly flows out from throttling groove like this, cause the throttling capacity deficiency, because the deficiency of throttling capacity makes the fluid turbulence instability, influenced the performance and the life-span of product.
As mentioned above, there is following deficiency in prior art: the throttling capacity deficiency, and the fluid turbulence instability, the product performance instability, life of product is short.
Summary of the invention
The utility model has solved the throttle valve plate throttling capacity deficiency that prior art exists, can make the fluid turbulence instability, make the unstable properties of piston valve, cause short partially problem of life-span, a kind of shock absorber piston valve that restores the throttle valve plate new structure of having used is provided, and its throttling capacity is good, and internal-external heat exchange is stable, product performance are stable, and working life is long.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of shock absorber piston valve that restores the throttle valve plate new structure of having used, comprise piston, the flowing valve spring sheet that described piston upper-end surface is provided with, recovery throttle valve plate, recovery valve block, the centering spring seat that described piston lower surface inboard sets gradually, it is characterized in that described recovery throttle valve plate is provided with some throttling grooves, described throttling groove comprises kidney slot and coupled logical gap slot.The circumferential cross-section length of described kidney slot is longer than the circumferential cross-section length of gap slot; The radial cross section length of described kidney slot is longer than the radial cross section length of gap slot.During work, fluid is postponed and is descended from piston rod, flows through from the throttling groove that restores throttle valve plate, produces the needed hydraulic coupling of vibration damper; When fluid flows through, flowing through big captured area earlier is to be that gap slot flows out from little big restriction again behind the kidney slot, increased the wetted perimeter length of restoring throttle valve plate like this, thereby increased hydraulic radius, know that by fluid mechanics this thunder Lip river number that will increase and decrease fluid (represent with symbol Re by the Lei Luo number, its mathematic(al) representation is Re=duP/mu, and d is a warp in the pipeline, and u is a rate of flow of fluid, p is a fluid density, mu is a fluid viscosity), make fluid turbulence in stable condition, and stable turbulent flow can be so that restore the throttle valve plate working stability, internal-external heat exchange is stable, play the effect of fluid steady flow, improved the stability hydraulic performance of product, the working life of also having improved product.
As preferably, described throttling groove is 1～5.Select the number of throttling groove according to the actual demand of vibration damper throttling capacity.
The utility model is skillfully constructed, change to throttling grooves structure, the feasible generation flowed out from the little gap slot of area after the needed hydraulic coupling of vibration damper flows through large-area kidney slot earlier again, thereby played the effect of fluid steady flow, improved the stability hydraulic performance of product.

Fig. 2 is the structural representation that restores throttle valve plate.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1.See Fig. 1 and Fig. 2, a kind of shock absorber piston valve that restores the throttle valve plate new structure of having used of this example, comprise piston 1, the flowing valve spring sheet 3 that described piston 1 upper-end surface is provided with, the recovery throttle valve plate 2 that inboard, described piston 1 lower end surface sets gradually, restore valve block 5, centering spring seat 4, centering spring seat 4 is provided with return spring 9, return spring 9 is positioned at the radial outside that restores nut 8 simultaneously, these part centers that are successively set on the piston 1 are assembled together by piston rod 7, described recovery throttle valve plate 2 is provided with 1 throttling groove 6, and described throttling groove 6 comprises kidney slot 61 and coupled logical gap slot 62.The circumferential cross-section length of described kidney slot 61 is longer than the circumferential cross-section length of gap slot 62; The radial cross section length of described kidney slot 61 is longer than the radial cross section length of gap slot 62.
During work, fluid is postponed and is descended from piston rod, flows through from the throttling groove that restores throttle valve plate, produces the needed hydraulic coupling of vibration damper; When fluid flows through, flowing through big captured area earlier is to be that gap slot flows out from little big restriction again behind the kidney slot, this will increase the thunder Lip river number of fluid, make fluid turbulence in stable condition, stable turbulent flow can make and restore the throttle valve plate working stability, internal-external heat exchange is stable, thereby the stable prod performance improves life of product.
