Abstract
The utility model relates to the technical field of expansion joints, and particularly relates to a simple sleeve expansion joint. The simple sleeve expansion joint comprises an outer casing tube and a movable tube, wherein the outer layer of the movable tube is sleeved with the outer casing tube; a seal groove is formed between the outer wall of the movable tube and the inner wall of the outer casing tube; and gland packing is filled into the seal groove. According to the simple sleeve expansion joint, the seal groove is formed between the outer wall of the movable tube and the inner wall of the outer casing tube, and the gland packing is filled into the seal groove; sealing of the expansion joint is further improved through the gland packing, so that the use performance of the expansion joint is improved, and the service life of the simple sleeve expansion joint is prolonged. Besides, the simple sleeve expansion joint has the advantages of simple structure, low manufacturing cost and the like.
Description
Technical field
The utility model relates to the slip joint technical field, is specifically related to single entry sleeve slip joint.
Background technique
Slip joint is also referred to as pipeline expansion joint, expansion joint, compensator or expansion bend, on the penstock road, has the pipeline section that can freely stretch with micro-angular deflection and good seal performance, be used for to adapt to the angular displacement that steel pipe produces axial displacement and takes place because of reasons such as building differential settlements because of temperature influence, and be convenient to install steel pipe.But because existing its function of slip joint is more, thereby complex structure, preparation process is loaded down with trivial details, manufacture cost is high, and sealing is poor, reduces usability, reduction of service life.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, low cost of manufacture, good airproof performance, the raising single entry sleeve slip joint in working life.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: single entry sleeve slip joint, comprise outer sleeve and mobile pipe, the skin of described mobile pipe is socketed with outer sleeve, form seal groove between the outer wall of described mobile pipe and the inwall of described outer sleeve, fill stuffing box packing in the described seal groove.
Further, described stuffing box packing is the graphite grazing filler.
Further, an end of described seal groove is provided with friction top, and described friction top is fastenedly connected by flange and described outer sleeve and mobile pipe.
Further, described flange is fixed by hold-down bolt.
Further, the tapered pipe of an end of described outer sleeve.
The utlity model has following beneficial effect: single entry sleeve slip joint described in the utility model, comprise outer sleeve and mobile pipe, wherein, between the inwall of the outer wall of mobile pipe and outer sleeve, form seal groove, and filling stuffing box packing in the seal groove; The utility model further improves the sealing of slip joint by stuffing box packing, thereby improves flexible usability, and prolongs its working life.In addition, the utlity model has characteristics such as kind is simple in structure, low cost of manufacture.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
As shown in Figure 1, single entry sleeve slip joint comprises outer sleeve 1 and mobile pipe 2, and the skin of described mobile pipe 2 is socketed with outer sleeve 1, forms seal groove 3 between the outer wall of described mobile pipe 2 and the inwall of described outer sleeve 1, fills stuffing box packing in the described seal groove 3; In the present embodiment, fill stuffing box packing in the seal groove between mobile pipe and outer sleeve, make to guarantee the sealing effect of slip joint equally when mobile pipe moves freely in outer sleeve, thus the usability of raising slip joint.
Described stuffing box packing is the graphite grazing filler, because the graphite grazing filler has characteristics such as corrosion-resistant, high pressure resistant and high temperature resistant, thereby can prolong the working life of slip joint.
One end of described seal groove 3 is provided with friction top 4, and described friction top 4 is fastenedly connected by flange 5 and described outer sleeve 1 and mobile pipe 2, adopt the effect of flange be to make between friction top and outer sleeve and the mobile pipe be connected more fastening, firm.
Described flange 5 is fixing by hold-down bolt 6, by the hold-down bolt fastening flange, is convenient to easy for installation.
The tapered pipe 7 of one end of described outer sleeve 1, the purpose that is designed to conical pipe can directly be plugged in the pipeline slip joint, and is easy for installation, time saving and energy saving.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
