Abstract
The utility model relates to a kind of wear resistant packing box.Mainly solve the problem that packing_seal is poor, the rear interpolation of wearing and tearing is inconvenient of existing stuffing box for oil field well head.It is characterized in that: described bulb sleeve pipe (14) inside is equipped with copper lower supporting positive cover (13), lower supporting positive cover (13) top is equipped with Cowhells packing (12), Cowhells packing (12) top is compressed by pressure pad (11), described main casing body (9) inside is filled with spherical rubber particles (10), and the top of spherical rubber particles (10) is equipped with sealed packing (8) and spring base supporting positive cover (7) successively, spring base supporting positive cover (7) top is fixed with spring (4) by lower spring cup (5).This packing box has the feature of easy compression, good airproof performance, easily interpolation packing.
Description
Technical field
The utility model relates to a kind of oilfield, specifically a kind of wear resistant packing box.
Background technology
The packing that current stuffing box for oil field well head adopts is mostly rubber helical packing, not easily compresses because hardness is higher, causes sealing poor, and after packing wearing and tearing, add packing inconvenient.
Summary of the invention
Add inconvenient deficiency in order to the packing_seal overcoming existing stuffing box for oil field well head is poor, wearing and tearing are rear, the utility model provides a kind of wear resistant packing box, and this packing box has easy compression, good airproof performance, easy feature of adding packing.
The technical solution of the utility model is: a kind of wear resistant packing box, comprise main casing body, main casing body lower end is connected on bulb sleeve pipe, described bulb inside pipe casing is equipped with copper lower supporting positive cover, lower supporting positive cover top is equipped with Cowhells packing, and Cowhells packing top is compressed by pressure pad, and described main casing body inside is filled with spherical rubber particles, and the top of spherical rubber particles is equipped with sealed packing and spring base supporting positive cover successively, spring base supporting positive cover top is fixed with spring by lower spring cup.
Described spring base supporting positive cover is connected by red copper riveting pin with between lower spring cup, and the upper end of spring is connected with upper spring seat, and the top of upper spring seat is provided with upper pressing cap, and the lower end of upper pressing cap is connected on main casing body.
The utility model has following beneficial effect: owing to taking such scheme, and main casing body inside is equipped with spherical rubber particles packing, and compared with existing Screw disk-seal tube, spherical rubber particles packing more easily compresses, and elasticity is better, adds sealing; Its abrasion resistance is good, extends application life; Meanwhile, add upon wear conveniently.Spherical rubber particles packing top is provided with spring, and after packing wearing and tearing, the elastic force of spring is compressed, and makes packing remain impaction state, makes sealing effectiveness better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-upper pressing cap in figure, the upper supporting positive cover of 2-, 3-upper spring seat, 4-spring, 5-lower spring cup, 6-red copper riveting pin, 7-spring base supporting positive cover, the upper sealed packing of 8-, 9-main casing body, 10-spherical rubber particles, 11-pressure pad, 12-Cowhells packing, supporting positive cover under 13-, 14-bulb sleeve pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of wear resistant packing box, comprises main casing body 9, and main casing body 9 lower end is connected on bulb sleeve pipe 14, and described bulb sleeve pipe 14 inside is equipped with copper lower supporting positive cover 13, and lower supporting positive cover 13 is copper, more wear-resisting.Lower supporting positive cover 13 top is equipped with Cowhells packing 12, and Cowhells packing 12 top is compressed by pressure pad 11, and along being on bulb sleeve pipe 14 end face on pressure pad 11.Described main casing body 9 inside is filled with spherical rubber particles 10, and the top of spherical rubber particles 10 has been placed in sealed packing 8, upper sealed packing 8 top is equipped with spring base supporting positive cover 7, spring base supporting positive cover 7 top is connected with lower spring cup 5, and is connected by red copper riveting pin 6 between spring base supporting positive cover 7 with lower spring cup 5.Lower spring cup 5 top is fixed with spring 4, and the upper end of spring 4 is connected with upper spring seat 3, and the top of upper spring seat 3 is connected with supporting positive cover 2, and upper supporting positive cover 2 outside is provided with upper pressing cap 1, and the lower end of upper pressing cap 1 is connected on main casing body 9.
This packing box is owing to adopting spherical rubber particles packing, and compared with existing Screw disk-seal tube, spherical rubber particles packing more easily compresses, and elasticity is better, adds sealing; Its abrasion resistance is good, extends application life; Meanwhile, add upon wear conveniently.Spherical rubber particles packing top is provided with spring 4, after packing wearing and tearing, and the upper sealed packing 8 of elastic force compression of spring 4, thus spherical rubber particles 10 is compressed, make spherical rubber particles packing remain impaction state, sealing effectiveness is better.
