Description

A kind of pipeline internal expansion type leak detection seal plug
Technical field
The utility model is related to technical field of sealing technology, are specifically related to a kind of pipeline internal expansion type leak detection seal plug.
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 When detection, nowadays people often use and think to fill in plug at nozzle, are sealed to tube body using plug, such 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 Plug is just particularly important
Invention content
The utility model makes its deformation by crush seal circle, is sealed using the sealing ring line up of deformation, significantly Improve its working efficiency;A kind of pipeline internal expansion type leak detection seal plug is provided.
In order to solve the above technical problems, the utility model provides a kind of pipeline internal expansion type leak detection seal plug, including
The inside of sealing ring, the sealing ring is in hollow shape,
End is squeezed, the extruding end is detachably connected to the right end of sealing ring 1,
Drive link, the drive link are removably connected by connecting seat and cylinders, the left end of the drive link It is connected in connecting seat, the right end of the drive link stretches into sealing ring and is connected with end is squeezed.
Further:The both ends of the sealing ring are in planar, and the sealing ring is made of silica gel.
Further:The right end of the connecting seat offers pilot hole, and the left end of the drive link is movably connected in In pilot hole, it is further opened with the first threaded hole on the connecting seat side wall, is connected in first threaded hole and holds out against spiral shell Bolt, the puller bolt are connected across the first threaded hole with drive link.
Further:The right end of the drive link offers the second threaded hole, and sealing ring is stretched into the extruding end Interior one end is provided with the external connection screw to match with the second threaded hole, and the extruding end passes through external connection screw and the second spiral shell The cooperation of pit is detachably connected on drive link.
With the above structure, the utility model makes its deformation by crush seal circle, using the sealing ring of deformation to pipe Mouth is sealed, and substantially increases its working efficiency;And the design also has simple in structure, easily fabricated and practicality and high efficiency The advantages of.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
A kind of pipeline internal expansion type leak detection seal plug as shown in Figure 1, including sealing ring 1, extruding end 2 and drive link 3, the inside of the sealing ring 1 is in hollow shape, and the extruding end 2 is detachably connected to the right end of sealing ring 1, described Drive link 3 by connecting seat 4 and cylinders, the left end of the drive link 3 is detachably connected in connecting seat 4, institute The right end for the drive link 3 stated stretches into sealing ring 1 and is connected with end 2 is squeezed, the both ends of the sealing ring 1 be in it is planar, The sealing ring 1 is made of silica gel, and the outside of the drive link 3 is provided with shell, the left end of the sealing ring 1 It is connected with shell.The utility model makes its deformation by shell and extruding 2 crush seal circle of end, utilizes the sealing ring pair of deformation Nozzle is sealed, and substantially increases its working efficiency.
The right end of connecting seat 4 as shown in Figure 1 offers pilot hole, and the left end of the drive link 3, which is movably connected in, leads Into hole, it is further opened with the first threaded hole 5 on 4 side wall of connecting seat, is connected in first threaded hole 5 and holds out against spiral shell Bolt, the puller bolt are connected with drive link 3 across the first threaded hole 5, can be stretched to drive link 3 by using above structure The length entered in connecting seat 4 is adjusted, and plays the role of increasing practical performance.
The right end of above-mentioned drive link 3 offers the second threaded hole, and one in sealing ring 1 is stretched into the extruding end 2 End is provided with the external connection screw to match with the second threaded hole, and the extruding end 2 passes through external connection screw and the second threaded hole Cooperation be detachably connected on drive link 3.The design has the advantages that simple in structure, easily fabricated and practicality and high efficiency.
