Abstract
The utility model discloses a sealing sleeve suitable for pipeline inserting connection. The sealing sleeve comprises a cylindrical sleeve body, and is characterized in that the top of the sleeve body is open, an annular boss is outwardly formed on the top of the sleeve body, cylindrical holes are formed in the boss, and the axis of each cylindrical hole is parallel to that of the sleeve body; a circular through hole is formed in the bottom of the sleeve body, and the axis of the circular through hole coincides with that of the sleeve body. The sealing sleeve has the advantages of being simple in structure and easy to manufacture; the cylindrical holes are formed in the annular boss on the top of the sleeve body, thus, the shape of the annular boss can be changed easily, pipes can be effectively sealed even though errors are caused by tolerance in the pipe manufacturing process, and therefore the phenomenon of leakage can be effectively avoided; the bottom of the sleeve body is not completely open and provided with the circular through hole, therefore, the sealing sleeve can be conveniently arranged on the pipes in a sleeved mode and is not prone to reversal dislocation under pushing force, and the sealing sleeve effectively solves the problem of difficult location of a rubber ring in a connection port.
Description
Technical field
The utility model relates to a kind of stuffing box gland, is specifically related to a kind of stuffing box gland that pipeline is pegged graft that is applicable to, and belongs to technical field of sealing technology.
Background technique
The pipeline of transport gas, the sealing between its tube and tube adopts rubber ring to complete usually, but existing rubber ring can't guarantee the error caused due to the tolerance in the tubing manufacture process, thus easy to leak.In addition, existing rubber ring is located difficult in birdsmouth, is subject to thrust easily to cause the reversion dislocation, thereby cause outside the birdsmouth outside, moves, and makes seal failure.So, need to be improved the existing structure that is used in the seal ring of pipeline splicing position.
The model utility content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of good seal performance and location to be applicable to easily the stuffing box gland that pipeline is pegged graft.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
A kind of stuffing box gland that is applicable to the pipeline grafting, comprising: columnar cover body is characterized in that, the open-topped of aforementioned cover body, and outwards be formed with annular boss, on aforementioned annular boss, be formed with cylindrical hole, the axis of aforementioned cylindrical hole is parallel with the axis of cover body; The bottom of aforementioned cover body is formed with manhole, the axis of aforementioned circle through hole and the dead in line of overlapping body.
The aforesaid stuffing box gland that is applicable to the pipeline grafting is characterized in that aforementioned cylindrical hole is uniformly distributed on annular boss.
The aforesaid stuffing box gland that is applicable to the pipeline grafting is characterized in that aforementioned cylindrical hole is distributed on a concentric circle of annular boss.
The aforesaid stuffing box gland that is applicable to the pipeline grafting is characterized in that aforementioned cylindrical hole is distributed on two concentric circles of annular boss.
The aforesaid stuffing box gland that is applicable to the pipeline grafting, is characterized in that the cylindrical hole cross arrangement on aforementioned two concentric circles.
The aforesaid stuffing box gland that is applicable to the pipeline grafting is characterized in that the outside of the bottom of aforementioned cover body is formed with chamfering.
The aforesaid stuffing box gland that is applicable to the pipeline grafting, is characterized in that, aforementioned stuffing box gland adopts rubber to make.
Usefulness of the present utility model is: structure is relatively simple, easily manufactures; Be formed with cylindrical hole on the annular boss of cover bodies top, make the shape of annular boss easily change, even tubing poor error that caused on business in manufacture process also can effectively be sealed tubing, thereby effectively avoided the generation of the situation of seepage; The bottom of cover body is fully not unlimited, is formed with manhole, can be enclosed within easily on tubing, is difficult for occurring the reversion dislocation under thrust, efficiently solves rubber ring and locate difficult problem in birdsmouth.
The accompanying drawing explanation
Fig. 1 is the structural representation that is applicable to a specific embodiment of the stuffing box gland that pipeline pegs graft of the present utility model;
Fig. 2 is the plan view of the stuffing box gland in Fig. 1.
The implication of reference character: 1-cover body in figure, 2-annular boss, 3-cylindrical hole, 4-manhole, 5-chamfering.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
See figures.1.and.2, the stuffing box gland that is applicable to the pipeline grafting of the present utility model comprises: columnar cover body 1, and the open-topped of cover body 1, bottom is formed with manhole 4, the axis of manhole 4 and the dead in line of overlapping body 1.Wherein, the open-mouth at cover body 1 top outwards is formed with annular boss 2, is formed with cylindrical hole 3 on annular boss 2, and the axis of cylindrical hole 3 is parallel with the axis of cover body 1.
Stuffing box gland of the present utility model, owing to being formed with cylindrical hole 3 on annular boss 2, make the shape of annular boss 2 easily change, even tubing poor error that caused on business in manufacture process, also can effectively to tubing, be sealed, thereby effectively avoided the generation of the situation of seepage; In addition, the bottom of cover body 1 is fully not unlimited, is formed with manhole 4, can be enclosed within easily on tubing, is difficult for occurring the reversion dislocation under thrust, efficiently solves rubber ring and locate difficult problem in birdsmouth.
As a kind of preferred scheme, cylindrical hole 3 is uniformly distributed on annular boss 2.
More preferably, cylindrical hole 3 is distributed on a concentric circle of annular boss 2, or on two concentric circles.
When cylindrical hole 3 is distributed on two concentric circles of annular boss 2, the preferred cross arrangement of cylindrical hole 3 on two concentric circles.
For annular boss 2 can comparatively easily be out of shape with the formed gap of better closed conduit splicing position, as a kind of preferred scheme, stuffing box gland adopts rubber to make, non-rigid, easily produces deformation.
As a kind of preferred scheme, the outside of bottom of cover body 1 is formed with chamfering 5, thereby but increased the contact of stuffing box gland of the present utility model and pipeline, be convenient to the assembling of part.
It should be noted that, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
