Adhesive force between plastic lining layer 7 and core.On the one hand straight groove is only arranged on core axle 2, it is impossible to ensure lining plastic on spheroid 1
Layer 7 is relatively fixed, on the other hand the structure of straight groove, there is that plastic lining layer 7 is easy to fall off and peeling in ball valve use.
Utility model content
Technical problem to be solved in the utility model is：In order to overcome deficiency of the prior art, the utility model is carried
For a kind of lining plastic core structure, by changing and increasing plastic lining layer attaching structure, the adhesive force between plastic lining layer and core is improved,
Avoid coming off and peeling off for plastic lining layer.
The utility model solves its technical problem technical scheme to be taken：A kind of lining plastic core structure, including one
The spheroid and core axle of body connection, the spheroid middle part are provided with medium flow field through hole, and some connection media are additionally provided with the spheroid
The lining plastic through hole of opening and outer surface of spheroid, the core axle outside is equipped with lining plastic groove, the width at the lining plastic channel opening end
Less than the Breadth Maximum inside lining plastic groove, the spheroid, core axle and flow of media hole surface lining plastic have integrally formed lining to degree
In modeling layer, and the plastic lining layer insertion lining plastic through hole and lining plastic groove.
Further, the lining plastic through hole includes oblique through hole and clear opening, and the oblique through hole is positioned close to the one of core axle
On hemisphere, the clear opening is arranged far from a hemisphere of core axle, and the axis of the oblique through hole is by the spheroid
The centre of sphere, the axis of the clear opening is vertical with the axis of the medium flow field through hole.
Preferably, the axis of the oblique through hole and the angle α of the core axle axis are 25 ° -45 °.
Preferably, the cross sectional shape of the lining plastic groove is swallow-tail form or discount vibram outlet shape.
Further, the outer surface of the spheroid and core axle is provided with track line.
A kind of lining plastic core structure that the utility model is provided, old structure is improved, with following beneficial effect：
1. straight groove on core axle is improved to the small groove of inner space big opening, such as：Dovetail groove, discount vibram outlet connected in star
Deng to increase the pulling force of plastic lining layer and metal level, preventing plastic lining layer from coming off and peeling off；
2. track line is machined with metal level outer surface, increases the roughness on surface, increase the contact area of plastic lining layer, carried
The adhesive force of plastic lining layer high；
3. lining plastic through hole is machined with spheroid so that plastic lining layer runs through the spheroid of core, on the one hand in discharge plastic lining layer
Air, prevent thering is bubble to produce in plastic lining layer, on the other hand prevent plastic lining layer from peeling occur.
The new lining plastic core structure, improves the lining plastic quality of lining plastic core, while so that the use longevity of lining plastic core
Life increases.
