Description
Technical field
The utility model relates to a kind of wear-resistant valve rods of precision.
Background technique
By-passing valve is widely used in every field as the valve being mounted on by-pass line, just because of it is as peace
All risk insurance barrier, it is more demanding that industry is used for life and reliability, and in particular for precision instrument, valve rod is the important of by-passing valve
Component, wearability are that people want to break through always, but that expensive material is usually taken is wear-resisting to obtain for current mode
Property, higher cost, it is desirable to have better scheme to be substituted.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of wear-resistant valve rods of precision.
The utility model is achieved through the following technical solutions:
Accurate wear-resistant valve rod, including stainless steel interior bar, if uniform intervals are equipped on the outer surface of the stainless steel interior bar
Dry big protrusion and small protrusion, the big protrusion and small protrusion are integrally formed with stainless steel interior bar, between big protrusion, in small protrusion
Side, is inlaid with several arc-shaped nano ceramics pieces, recessed equipped with matching with small protrusion on nano ceramics piece bottom surface
Slot, the upper surface of the nano ceramics piece are arc structure.
Preferably, being filled with inorganic stickup resistant to high temperature between the nano ceramics piece and stainless steel interior bar contact surface
Agent.
The beneficial effects of the utility model are:
The stem structure of the utility model is ingenious, and abrasion resistance properties are very superior, and structure is firm, and low cost, is worth
It promotes.
Detailed description of the invention
The utility model is described in detail by following specific embodiments and drawings for ease of explanation,.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, accurate wear-resistant valve rod, including stainless steel interior bar 1, on the outer surface of the stainless steel interior bar 1
It is even to be equipped at intervals with several big raised 2 and small by raised 3, described big raised 2 and small raised 3 and be integrally formed with stainless steel interior bar 1, big
Between protrusion 2, small raised 3 top, be inlaid with several arc-shaped nano ceramics pieces 4, on 4 bottom surface of nano ceramics piece,
Equipped with the groove matched with small raised 3, the upper surface of the nano ceramics piece 4 is arc structure.
Inorganic alite paste resistant to high temperature is filled between 1 contact surface of the nano ceramics piece 4 and stainless steel interior bar.
The stem structure of the utility model is ingenious, and abrasion resistance properties are very superior, and structure is firm, and low cost, is worth
It promotes.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
