Description
Technical field
The invention belongs to high speed motor car technical field, high speed motor car oil-pressure damper technical field and specific is especially related to
It is related to a kind of high speed motor car oil-pressure damper core valve base.
Background technology
Oil-pressure damper is the damped part on high-speed railway locomotive vehicle, to the kinetic stability of rolling stock and comfortable
Property plays an important role.With the continuous improvement of modern rolling stock such as high ferro speed, vehicle is to each of oil-pressure damper
Item performance requirement is also higher and higher.However the valve seat of traditional vibration damping is an integral structure with guide cover, and the precision of valve seat is had
A degree of influence, and there are difficulty of processing it is big the problem of.
Fig. 1 is the valve architecture schematic diagram of oil-pressure damper, with reference to Fig. 1, can usually be existed during fluid flows
Core valve seat leaks caused by coordinating untight problem with core valve, prevents absorber damping force from meeting requirement, main
The reason is that the precision due to core valve seat cannot meet design requirement, there are serious for this stability and reliability to damper
Test.
Invention content
The present invention in view of the deficiencies of the prior art, is improved the core valve seat of the tune valve system of damper, by core
Valve seat, which is separately separated out, to be processed, and not only can be avoided worker's error leads to the waste of bulk raw material, but also can reduce core valve
The difficulty of processing of seat improves precision, meanwhile, the performance requirements with the high-precision cooperation of core valve of damper core valve seat is improved, is increased
Add the Stability and dependability of Vehicle damper.
In order to solve the above technical problems, the technical solution that the present invention takes is：
The present invention proposes a kind of high speed motor car oil-pressure damper core valve base, and the valve seat is hollow columnar structures, thereon
Portion's outer wall is equipped with hexagonal screw thread, and for being threadedly coupled with the guide cover of the oil-pressure damper, the middle part outer wall of the valve seat is set
Fluted, for installing sealing element, the lower part outer wall of the valve seat is ladder-type structure, is pacified for coordinating with damper core valve
Dress.
Further, the valve seat is steel material.
Further, the sealing element is gasket.
Further, the gasket is rubber material.
Beneficial effects of the present invention include at least：
1）Core valve seat is changed to split type processing by the integral type processing of script, ensures that core valve seat preferably coordinates with core valve, drops
Low difficulty of processing enhances the stability of damper.
2）Avoid that monoblock type valve seat machining accuracy is low, worker, which slips up, leads to the waste of bulk raw material.
