Description
Technical field
This utility model belongs to pipe fitting technical field, is specifically related to one and can realize self-packing pipe fitting.
Background technology
Pipe fitting is the part that pipe connects into pipeline.Socket fitting, threaded fitting, method can be divided into according to method of attachment
Blue pipe fitting and weld-end fittings four class.The multiplex material identical with pipe is made.There are elbow (ell), flange, tee T, four-way pipe
(crosshead) and reduced pipe (concentric reducer) etc..Elbow is for the place of pipeline turning；Flange is used for making pipe interconnect mutually with pipe
The part connect, is connected to pipe end, the place that tee T collects for three pipes；The ground that four-way pipe collects for four pipes
Side；Reduced pipe is used for the place that the two tubes of different tube diameters is connected.Current pipe fitting is generally and uses plastic pipe or gold
Belong to pipe fitting, such as cast iron pipe fittings, but no matter be to use what pipe fitting, be the most all directly on pipe fitting inner wall, to open threaded joints
Or have male threaded joint, it is directly connected to pipeline, when the pipe fitting of this structure connects, due between pipe fitting joint and pipe fitting
Diameter there are differences, poor sealing performance, seals to this end, be typically to be provided with sealing member when mounted, in case the generation of leak-stopping liquid, this
Sample operates cumbersome, is unfavorable for that installs is smoothed out.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem and provide one can realize self-packing pipe fitting.
For achieving the above object, this utility model adopts the following technical scheme that
One can realize self-packing pipe fitting, the pipe fitting body being made including metal, and described pipe fitting body has use
It is sticked on the internal thread part that external screw thread is mutually threaded, the inwall of described internal thread part one and has used bala gutta material system
The sealing shroud made, the outboard end of described sealing shroud has the hem of a circle L-shaped, and the hem of described L-shaped is exposed to described pipe
The opening of part body is outer and mutually bonding with the end face of the open end side of described pipe fitting.
The length of described sealing shroud is identical with the length of described internal thread part.
Described pipe fitting body includes the first connecting portion, the second connecting portion and the 3rd connecting portion, described first connecting portion, second
Connecting portion and the 3rd connecting portion are connected together by T-shaped structure, described first connecting portion, the second connecting portion and the 3rd connecting portion
There is internal thread part, described internal thread part is respectively equipped with a described sealing shroud.
This utility model uses bala gutta material to make by being sticked on the inwall of the internal thread part of pipe fitting one
Sealing shroud, the outboard end of described sealing shroud has the hem of a circle L-shaped, and the hem of described L-shaped is exposed to described pipe fitting
The opening of body is outer and mutually bonding with the end face of the open end side of described pipe fitting, so makes internal thread part and male element
During connection, it is compressed between female thread and external screw thread by the sealing shroud that thickness is suitable so that the sealing property of the two is able to
Strengthen, eliminate the trouble being wound around band, and owing to the outside of sealing shroud is provided with hem, again by flanging after pipe fitting connects
Portion is pressed in seam and forms a sealing ring, plays the effect of dual-seal.
Accompanying drawing explanation
Fig. 1 illustrates the structural representation realizing self-packing pipe fitting of the present utility model；
Fig. 2 illustrates the schematic side view realizing self-packing pipe fitting of the present utility model；
Fig. 3 illustrates the schematic side view realizing self-packing sealing shroud of the present utility model.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but this practicality is new
Type is not limited to listed embodiment.
Seeing shown in Fig. 1-3, one can realize self-packing pipe fitting, the pipe fitting body 100 being made including metal, institute
State pipe fitting body to have for the mutually threaded internal thread part 10 of external screw thread, the inwall of described internal thread part has been sticked one
Using the sealing shroud 20 that bala gutta material makes, the outboard end of described sealing shroud has the hem 21 of a circle L-shaped, described L
The opening that the hem of shape is exposed to described pipe fitting body is outer and mutually bonding with the end face 11 of the open end side of described pipe fitting.
Implementing, the length of described sealing shroud is identical with the length of described internal thread part, it is also possible to differ, or
It is the length slightly shorter than female thread, does not limits.
Wherein, described pipe fitting body includes the first connecting portion, the second connecting portion and the 3rd connecting portion, and described first connects
Portion, the second connecting portion and the 3rd connecting portion are connected together by T-shaped structure, described first connecting portion, the second connecting portion and
Three connecting portions have internal thread part, are respectively equipped with a described sealing shroud in described internal thread part.
Described sealing shroud 20 can use the material injection with self-adhering property to be formed, and so has necessarily at material itself
Cementability, directly can realize sealing shroud contact portion corresponding with pipe fitting itself by product itself and carry out bonding without taking off
Fall.
As an embodiment, described sealing shroud 20 can also be to be suppressed with external screw thread on outer wall 22, with described interior spiral shell
The screw-internal thread fit in stricture of vagina portion 10 realizes being threaded togather realization.
Like this, described sealing shroud 20 can be use non-adhesive material make can also, directly employing membrane material system
Work can realize corresponding function.
The thickness of described sealing shroud 20 can be actual setting, further, the most real in order to realize
Now seal, described sealing shroud 20 can use multiple structure, each layer can be separated from each other, so when excessively thick, permissible
Throw off one layer or layer after install again in internal thread part and use, thus further strengthen the convenience of operation.
More than analyze, it can be seen that this utility model is adopted by being sticked on the inwall of the internal thread part of pipe fitting one
The sealing shroud made by bala gutta material, the outboard end of described sealing shroud has the hem of a circle L-shaped, the folding of described L-shaped
The opening that edge is exposed to described pipe fitting body is outer and mutually bonding with the end face of the open end side of described pipe fitting, in so making
When threaded portion is connected with male element, it is compressed between female thread and external screw thread by the sealing shroud that thickness is suitable so that
The sealing property of the two is enhanced, and eliminates the trouble being wound around band, and owing to the outside of sealing shroud is provided with hem,
Hem is pressed in again seam and forms a sealing ring by pipe fitting after connecting, play the effect of dual-seal.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and
Retouching also should be regarded as protection domain of the present utility model.
