Abstract
The invention relates to a valve seat with pressure resistance. The valve seat comprises a valve body of a hollow structure. A first cylinder, a step ring body, a second cylinder and a small- external diameter cylinder are sequentially arranged on the valve body. The outer surface of the valve body is wrapped with a pressure-resistant layer. The valve seat with pressure resistance has following beneficial effects: the valve seat with pressure resistance is simple in structure and fine in anti-compression performance and is used conveniently and not easily damaged; safety and reliability are obtained; and service lifetime of the valve seat is prolonged.
Description
Technical field
The present invention relates to a kind of valve seat with withstand voltage properties.
Background technique
Automobile absorber is a kind of damping member, it is one of important component of automobile suspension system, to the smoothness that vehicle travels, travelling comfort, Security, steering operation and passing ability play conclusive effect, and wherein foot valve seat is one of strength member in automobile absorber.
Existing valve seat work in-process mainly adopts powder metallurgy pressing shaping, the valve seat of automobile absorber, when sharply shaking in vehicle traveling process, the impact force of hydraulic oil to outer ring valve block of high-speed motion is larger, long use can deform, in use crush easily, affect the using effect of valve seat, shorten the working life of vibration damper.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of valve seat with withstand voltage properties increasing working life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of valve seat with withstand voltage properties, comprise the valve body of hollow structure, described valve body is disposed with the first cylindrical body, step ring body and the second cylindrical body and little outer diameter cylindrical body, the outer surface of valve body is coated with Withstand voltage layer.
Further, the inwall of valve body of the present invention is provided with screw thread.
Further, the second cylindrical body of the present invention is provided with groove.
Further, chamfering at 45 ° is cut in step ring body of the present invention and the second cylindrical edge.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to use, has good crushing resistance, not fragile, safe and reliable, extends the working life of valve seat simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
