Description
Technical field
Technical field of sealing technology is the utility model is related to, is specifically related to a kind of pipeline internal expansion type leak detection sealing device.
Background technology
With the development of science and technology, requirement of the people for sealing device becomes higher and higher, especially carried out to tube body
During detection, nowadays people often use and think to fill in plug at the mouth of pipe, tube body are sealed using plug, such a mode is very
It is constant, and sealing effect does not reach requirement also, so designing a kind of pipeline internal expansion type leak detection sealing to solve the above-mentioned problems
Device is just particularly important.
The content of the invention
The utility model makes extruding termination and plug shell crush seal circle make its deformation, profit by pulling plug pull rod
With being sealed at pipe of the sealing ring of deformation to detecting tube body, the work efficiency of sealing is substantially increased；A kind of pipeline is provided
Internal expansion type leak detection sealing device.
To solve above-mentioned technical problem, the utility model provides a kind of pipeline internal expansion type leak detection sealing device, including
Cylinder,
Plug, the plug are made of plug shell, plug pull rod, sealing ring and extruding termination, and described is stifled
Head pull rod goes out shaft end with cylinder and is connected, and the plug shell is arranged on the outside of plug pull rod, and the one of the plug shell
End is fixedly connected on cylinder, and the other end of the plug shell is connected with sealing ring, one end of the plug pull rod according to
Secondary to be connected through plug shell and sealing ring with extruding termination, the sealing ring is between extruding termination and plug shell.
Further：The other end of the plug shell has also been removably installed nylon, and the plug shell passes through
The port of nylon detection tube body is connected.
Further：The both ends of the sealing ring are in plane, and the side of the sealing ring is oval.
Further：The sealing ring is made of silica gel.
Further：One end that the plug pull rod is connected with cylinder offers card slot, and the cylinder goes out shaft end
It is detachably connected in the card slot of plug pull rod.
With the above structure, the utility model makes extruding termination and the extruding of plug shell close by pulling plug pull rod
Seal makes its deformation, using being sealed at pipe of the sealing ring of deformation to detecting tube body, substantially increases the work effect of sealing
Rate；And the design also has the advantages that simple in structure, easily fabricated and practicality and high efficiency.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structure diagram of the utility model.
Embodiment
A kind of pipeline internal expansion type leak detection sealing device as shown in Figure 1, including cylinder 1 and plug 2, the plug 2 be
It is made of plug shell 2-1, plug pull rod 2-2, sealing ring 2-3 and extruding termination 2-4, the plug pull rod 2-2 and gas
Cylinder 1 goes out shaft end and is connected, and the plug shell 2-1 is arranged on the outside of plug pull rod 2-2, and the one of the plug shell 2-1
End is fixedly connected on cylinder 1, and the other end of the plug shell 2-1 is connected with sealing ring 2-3, the plug pull rod 2-
2 one end sequentially passes through plug shell 2-1 and sealing ring 2-3 and is connected with extruding termination 2-4, and the sealing ring 2-3 is positioned at crowded
Between pressure side head 2-4 and plug shell 2-1.The utility model squeezes extruding termination and plug shell by pulling plug pull rod
Pressure seal ring makes its deformation, using being sealed at pipe of the sealing ring of deformation to detecting tube body, substantially increases the work of sealing
Make efficiency.
The other end of plug shell 2-1 as shown in Figure 1 has also been removably installed nylon 4, the plug shell 2-1
The port that tube body 3 is detected by nylon 4 is connected, and by setting nylon 4 to prevent from damaging to tube mouth in connection, reduces
Unnecessary loss, plays the role of increasing practical performance.
The both ends of sealing ring 2-3 as shown in Figure 1 are in plane, and the side of the sealing ring 2-3 is oval, described
Sealing ring 2-3 be made of silica gel.
Above-mentioned plug pull rod 2-2 and one end that cylinder 1 is connected offer card slot, the cylinder 1 to go out shaft end removable
It is connected to unloading in the card slot of plug pull rod 2-2, the design has the advantages that simple in structure, easily fabricated and practicality and high efficiency.
