In addition, the utility model improves oneself of packing ring by being embedded with a turn in the inside of packing ring, by turn
Body intensity, further improve the service life of packing ring.
When the utility model produces, after preparing turn first, turn is placed on to the die cavity of circle body injection molding
It is interior, you can to obtain the circle body for being embedded with turn, be then coated with hydrophobic coating, the outer surface of hydrophobic coating in circle body outer surface
Adhere to arlt's strata.
Central axial direction using the circle body is upper and lower;
The circle body is provided with a lower annular recess that Open Side Down, the upper annular groove of an opening upwards;
Centerline axis parallel of the central axis of the lower annular recess and the upper annular groove with the circle body.
The utility model realizes the upper surface of circle body by being provided with lower annular recess and upper annular groove on circle body
There is a breach with lower surface, the contact area of circle body and installation place reduces, the effective pressure contact increase of circle body, and then increases
Sealing property.
1/3 of the width of the notch of the upper annular groove no more than circle body internal-and external diameter difference, and not less than 1/5;
1/3 of the width of the notch of the lower annular recess no more than circle body internal-and external diameter difference, and not less than 1/5.
The utility model is easy to ensure the sealing of circle body by limiting the width of rebate of upper annular groove and lower annular recess
It is cost-effective while performance.
The section of the lower annular recess is in inverted V-shaped, and the section of the upper annular groove is V-shaped;
The depth of the lower annular recess is the 1/5~1/6 of the thickness of the circle body, and the depth of the upper annular groove is
The 1/5~1/6 of the thickness of the circle body.
It is easy to ensure the self-strength of circle body.The thickness of circle body refers to the length along central axial direction of circle body.
The outer surface of the circle body is provided with projection, and the projection is stretched into the mesh of the arlt's strata.
The utility model is provided with projection by the outer surface of circle body, is easy to implement the limit effect of netted braiding layer.
The raised cross section is in regular hexagon, and the cross section of the mesh of the arlt's strata is also in regular hexagon.
It is easy to implement the fixed effect of arlt's strata.
Brief description of the drawings
Fig. 1 is the sectional drawing of packing ring of the present utility model;
Fig. 2 is a kind of structural representation of the utility model packing ring;
Fig. 3 is the phantom of the utility model packing ring.
Embodiment
