Abstract
The utility model relates to a highly hard wearing spiral packing set, which mainly solves the problem of prior packing set being poor in wearing resistance, short in service life and inconvenient in installation. The utility model is characterized in that a flexible body (2) is tube shaped and provided on the packing set surface with a spiral shaped nick (3); the flexible body (2) inner surface is fixed with a highly hard wearing layer (1). The utility model is good in wear resistance, long in service life and convenient in installation.
Description
Technical field:
The utility model relates to sealed packing, especially the high abrasion Screw disk-seal tube of sucker rod and well head sealing place in the oil recovery field, oil field.
Background technology:
In oil recovery field, oil field, be to use packing_seal between sucker rod and the rod-pumped well well head, ring formula sealed packing is housed in the packing box of well head.Because oil pumper is continuously worked, wearing and tearing increase sealing place gap and then produce and leak between sucker rod and the sealed packing, and the sealing packing wears no resistance, and must often change during production; It is made up of a plurality of assemblies in addition, must play dedolation to each assembly side when installing or changing, and installs by part then, installs inconvenient.
The utility model content:
Existing sealed packing wears no resistance in order to overcome, the life-span is short and inconvenient deficiency is installed, and the utility model provides a kind of high abrasion Screw disk-seal tube, and this high abrasion Screw disk-seal tube has that abrasion resistance is good, the life-span long and characteristics easy for installation.
The technical solution of the utility model is: this high abrasion Screw disk-seal tube comprises elastic body, and elastic body is that tubulose and its packing cornice have the spirality otch, and the elastic body inwall is fixed with high antifriction layer.
Above-mentioned elastic body and high antifriction layer are bonded as one.
The utlity model has following beneficial effect: because the elastic body in the such scheme is that tubulose and its packing cornice have the spirality otch, making this packing is one, convenient when installing or changing; The elastic body inwall is fixed with high antifriction layer, makes that this packing abrasion resistance is good, the life-span is long.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model;
Accompanying drawing 2 is lateral views of the present utility model.
1-high antifriction layer among the figure, 2-elastic body, 3-spirality otch.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in FIG., this high abrasion Screw disk-seal tube comprises elastic body 2, and elastic body 2 is a tubulose, and the inwall that helps elastic body 2 contacts with sucker rod, and the outer wall of elastic body 2 contacts with seal box; Have spirality otch 3 on elastic body 2 and high antifriction layer 1 wall, its two ends have an opening respectively, make this packing become one, are convenient to be installed between sucker rod and sealing close; Elastic body 2 inwalls are bonded with high antifriction layer 1, and elastic body 2 is an one with high antifriction layer 1, makes this packing abrasion resistance good, long service life.
During actual the use, open this packing one end opening and be clipped on the sucker rod, rotating missile gonosome 2 makes its inwall identical with sucker rod fully, then this packing seal box inward turning of packing into is pressed cap and is got final product.
Claims (2)
1, a kind of high abrasion Screw disk-seal tube comprises elastic body (2), it is characterized in that: elastic body (2) is for tubulose and its packing cornice have spirality otch (3), and elastic body (2) inwall is fixed with high antifriction layer (1).
2, high abrasion Screw disk-seal tube according to claim 1 is characterized in that: elastic body (2) is bonded as one with high antifriction layer (1).
