Description
Technical field
The utility model belongs to valve technology field, and in particular to a kind of wedge-type double-gate harden structure with the V-arrangement conical surface.
Background technology
Common spherical surface connection wedge-type double-gate harden structure as shown in Figure 1, be processed into spherical shape among flashboard A and flashboard B,
Flashboard A in this way and flashboard B can generate a micro rotation around spherical surface each other, to compensate the mismachining tolerance of key groove, and
The caused wedge angle variation of expanding with heat and contract with cold under high temperature can be compensated, high temperature stuck phenomenon is prevented.
It, can not possibly be completely ideal but since the spherical diameter of two shoe brake plates in process can not possibly be completely the same
Ground fits together, and therefore, in practical application, two not being bonded for spherical surface will produce friction larger than expected, and
And with the increase of running time, this friction constantly increases, finally so that spherical surface is from it is anticipated that generate rotation, to
Lead to bite phenomenon.
Invention content
The purpose of this utility model is to provide a kind of wedge-type double disc with the V-arrangement conical surface, and laminating degree is good, can prevent
Flashboard bite.
The technical solution of the utility model is as follows：
A kind of wedge-type double-gate harden structure with the V-arrangement conical surface, including flashboard A staggered relatively and flashboard B, the flashboard A
Interface is equipped with hemispherical protuberances, and the flashboard B interfaces are equipped with the V-arrangement conical surface, and the hemispherical protuberances are located at V-arrangement
In the conical surface, the vertex of the hemispherical protuberances is located at outside the interface where it, that is, is higher than interface, V-arrangement cone
The edge in face stretches out the interface of the flashboard A at place.
The flashboard A interfaces are equipped with deep gouge, and the hemispherical protuberances are located in deep gouge, and described is hemispherical convex
The overall diameter risen is less than deep gouge interior diameter.
The bottom of the hemispherical protuberances is equipped with cylindrical structure, the hemispherical protuberances and it is cylindrical for integral into
Type forms annular groove between integrally-built outer surface and the inner wall of deep gouge.
The outer wall at the edge of the V-arrangement conical surface is vertical with the interface at place, the 6 outer diameter size of edge of the V-arrangement conical surface with
Annular groove inner diameter size is equal.
The V-arrangement conical surface bottom centre is machined with circular groove.
The V-arrangement angle of the V-arrangement conical surface is at 90 ° to 120 °.
The beneficial effects of the utility model are as follows：Since the convex spherical of flashboard A and the V-arrangement concave cone face of flashboard B are with adaptive
Inherent characteristic in reply, therefore the convex spherical of flashboard A is rolled on the V-arrangement concave cone face of flashboard B always, so on the one hand two
Shoe brake plate will not generate the phenomenon that not being bonded due to processing dimension error, and friction will not increase with the running time increases
Greatly, on the other hand, since the convex spherical of flashboard A is rolled always on the V-arrangement concave cone face of flashboard B, an extruding force is generated, is played
Similar to the effect of grinding, with the increase of running time, due to the effect constantly ground, spherical surface can more tend to be smooth, and two
Friction between shoe brake plate can be on a declining curve, is more conducive to the movement of spherical surface, and being more conducive to prevents flashboard bite.

Specific implementation mode
Below by the drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figures 2 and 3, flashboard A1 and flashboard B2 are staggered relatively, and hemispherical protuberances are processed on the interface of flashboard A1,
The bottom of protrusion is cylinder, and cylindrical outer diameter size and bulb diameter is equal in magnitude.Hemispherical protuberances and cylinder are integrated
Processing, and the vertex of hemispherical protuberances 3 is located at outside the interface where it, i.e., higher than interface.
In the deep gouge 8 that above-mentioned hemispherical projections 3 and cylinder 7 are processed on the interface of flashboard A1, hemispherical projections 3
Annular groove 5, i.e. hemispherical projections 3 and cylinder are formed between the integrally-built outer surface formed of cylinder 7 and the inner wall of slot
The overall structure that shape 7 is formed is located at the center of the deep gouge 8.
The V-arrangement conical surface 4 outstanding is processed on the interface of flashboard A1, the edge 6 of V-shaped groove stretches out pair of the flashboard A1 at place
The outer wall of junction, the edge 6 of V-shaped groove 4 is vertical with the interface at place, 6 outer diameter size of edge and 5 internal diameter of annular groove of V-shaped groove
It is equal in magnitude.
In the V-arrangement conical surface, 4 bottom centre is machined with circular groove 9, is used as escape, the V-type conical surface easy to process.
For the cone angle of the V-arrangement conical surface 4 between 90 ° to 120 °, optimal value is 120 °.
Since the convex spherical of flashboard A and the V-arrangement conical surface of flashboard B have the inherent characteristic of adaptive centering, flashboard A's
Convex spherical is rolled on the V-arrangement conical surface of flashboard B always, is avoided since the spherical surface that processing dimension error generates is not bonded now
As simultaneously because the convex spherical of flashboard A is rolled always on the V-arrangement concave cone face of flashboard B, generating an extruding force, playing similar
In the effect of grinding, with the increase of running time, spherical surface can more tend to be smooth, under the friction between two shoe brake plates can be in
Drop trend is more conducive to the movement of spherical surface, and being more conducive to prevents flashboard bite.
