Abstract
The utility model relates to a compression valve subassembly structure which mainly comprises a compression valve seat, wherein, a valve seat through-hole and a group of throttle holes are arranged on the compression valve. A compression valve rod orderly penetrates through a compression valve plate, a compression throttle valve plate, the valve seat through-hole, a compensating valve plate and a compensating valve spring to be screwed with a compensating valve retainer. The compression valve plate and the compression throttle valve plate are tightly pressed on one side of the compression valve seat by one side end face of a compression valve rod. The compensating valve spring and the compensating valve plate are tightly pressed on the other side end surface of the compensating valve seat by the end face of the compensating valve retainer. The throttle holes are uniformly distributed along the circumferential direction. The compression valve plate comprises a first compression valve plate and a second compression valve plate. The compression valve subassembly structure has the beneficial effect of stable damping, convenient assembly and good fatigue performance by adopting the valve plate spring typed structure, realization of easy and convenient adjustment of compression damping force of different dampers, and good stability of the damping force of the damper, thereby being beneficial for improving the service life of the damper.
Description
Technical field
The utility model relates to the compression valve field, especially a kind of compression valve sub-assembly structure.
Background technique
Original compression valve sub-assembly structure mainly comprises self-cleaning and guide pillar sliding valve style, the throttle orifice size of the matching gap of guide pillar and guiding valve, guide pillar, spring height and rigidity are bigger to the damping force influence of vibration damper in the guide pillar slide-valve structure, and the conformity of damping force is relatively poor; When vibration damper is worked, because guiding valve moves on guide pillar, after use a period of time, will wear and tear, make the damping force bad stability.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of compression valve sub-assembly structure is provided.
The utility model solves the technological scheme that its technical problem adopts: this compression valve sub-assembly structure, mainly comprise the compression valve seat, the compression valve seat is provided with a valve seat through-hole and one group of throttle orifice, and described compression valve rod passes compression valve block, compression throttling valve block, valve seat through-hole, compensation valve block successively, the recuperation valve spring is connected with the recuperation valve stop screw; The end face of compression valve rod will compress valve block and the compression throttling valve block is pressed on compression valve seat one side end face, and the end face of recuperation valve snubber is pressed on recuperation valve spring and compensation valve block on the compression valve seat opposite side end face.
Described one group of throttle orifice is along the circumferential direction uniform.
Described compression valve block comprises the first compression valve block and the second compression valve block.
The effect that the utility model is useful is: adopt the valve block spring structure, damping is stable, and is easy to assembly, possesses good fatigue behaviour simultaneously, realizes that the compression damping power adjustment of different vibration dampers is easy, convenient; The damping force good stability of vibration damper, the working life that helps improving vibration damper.

Description of reference numerals: compression valve rod 1, the first compression valve block 2, the second compression valve blocks 3, compression throttling valve block 4, compression valve seat 5, valve seat through-hole 5-1, throttle orifice 5-2, compensation valve block 6, recuperation valve spring 7, recuperation valve snubber 8.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this compression valve sub-assembly structure mainly comprises compression valve seat 5, and compression valve seat 5 is provided with a valve seat through-hole 5-1 and one group of throttle orifice 5-2, and throttle orifice 5-2 is along the circumferential direction uniform.Described compression valve rod 1 passes the first compression valve block 2, the second compression valve block 3, compression throttling valve block 4, valve seat through-hole 5-1, compensation valve block 6, recuperation valve spring 7 successively and is threaded with recuperation valve snubber 8; The end face of compression valve rod 1 will compress valve block and compression throttling valve block 4 is pressed on compression valve seat 5 one side end faces, compression throttling valve block 4 glands are at throttle orifice 5-2, and the end face of recuperation valve snubber 8 is pressed on recuperation valve spring 7 and compensation valve block 6 on the compression valve seat 5 opposite side end faces.
The fluid compression valve of flowing through produces damping by the distortion of compression throttling valve block 4, recuperation valve spring 7 and the throttling of throttle orifice 5-2.The characteristics of this structure are: adopt the valve block spring structure, damping is stable, and is easy to assembly, possesses good fatigue behaviour simultaneously.Valve seat itself adopts metallic sintered products, the making aspect, and cost is low, is convenient to large-scale production.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
