Abstract
The utility model discloses a valve seat which can be tuned when in assembling. The valve seat comprises a body (1), wherein an end surface (2) of one end and a side surface (3) of the end of the body (1) are transitioned in an arc manner, the arc transition forms an annular arc surface (4) which is connected with the valve seat, and the annular arc surface (4) is respectively tangent to the end surface (2) and the side surface (3).
Description
Technical field
The utility model relates to vibration damper technical field, is specifically a kind of valve seat.
Background technique
One end of valve seat is generally provided with circular cone, concrete structure as application publication number be CN 102072273 A, notice of authorization number is CN 201866157 U, shown in the accompanying drawing of the files such as CN 202023877 U, this circular cone is for offseting and be connected with seat, the structure offseting after being connected with seat is as shown in the file map 1 that application publication number is CN 102072273 A, although connect respond well, but when assembling, cannot finely tune to meet the perpendicularity requirement of valve line, this is to valve seat, the manufacturing of the associated components such as seat has proposed very high requirement, if valve seat, the manufacturing of the associated components such as seat does not meet required precision, vibration damper performance, reliability and working life will be a greater impact.
Model utility content
The technical problems to be solved in the utility model is, the valve seat that can finely tune when a kind of assembling is provided.
The technical solution of the utility model is, the utility model valve seat, it comprises body, the side arc transition of the end face of body one end and described one end, this arc transition is formed for the annular arc surface being connected with seat, and this annular arc surface is tangent with described end face and side respectively.
Adopt after said structure, the utility model compared with prior art, have the following advantages: owing to being provided with respectively and the tangent annular arc surface of end face and side, so this annular arc surface is that line contacts while offseting with seat, like this, the utility model valve seat packs into when interior can swing fine setting to meet the perpendicularity requirement of valve line around axis, thereby the actual size of the associated components such as the valve seat that can obtain according to Practical manufacturing, seat is assembled, and meet final assembly precision requirement, and then improve vibration damper performance, reliability and working life; In addition, when existing powder metallurgical technique is manufactured, the structure of circular cone can cause falling slag defect, also produces burr simultaneously, and the utility model does not have these problems while adopting existing powder metallurgical technique to manufacture.
As improvement, the described body the other end is provided with axially two contour concentric valve lines, from being respectively outside to inside the first valve line and second valve line, between the first valve line and second valve line, be provided with circumferentially uniform a plurality of the first through flow holes, between second valve line and the central through bore of body, be provided with circumferentially uniform a plurality of the second through flow holes, the passage section of the first through flow hole is greater than the passage section of the second through flow hole, like this, through-flow smooth and easy vibration is little, thereby make annular arc surface more stable with the state that offsets of seat, and be more conducive to vibration damper and be quick on the draw.
As improvement, between adjacent the first through flow hole, be equipped with the projection for valve block being played a supporting role when the valve block axial deformation, each projection is circumferentially uniform, like this, can play enough supports to the micro-deformation of valve block, thereby prevent that valve block is out of shape excessive obstruction through flow hole, guaranteed valve block flatness, make damping capacity stable.
As improvement, the passage section of the first through flow hole is shaped as fan ring-type, and the passage section of the second through flow hole is shaped as circle, like this, is more conducive to flow control accurately stable.
As improvement, the first through flow hole and the second through flow hole arrange in pairs, the first through flow hole of every centering and the second through flow hole are all positioned in same radial alignment, and the first through flow hole that this is internal and the second through flow hole are all symmetrical about this radial alignment line, like this, be more conducive to flow control accurately stable.
