Description
Technical field
The utility model relates to sealing device technical fields, simple more particularly, to a kind of structure, easy to use, Neng Gouti
High working efficiency and sealing effect, the versatile sealing device for pipe heat exchanger fast blockage.
Background technique
After the leakage of pipe heat exchanger heat exchanger tube, generally uses seam leakage blinding or squeeze into taper plug, two sides block both
Processing mode, but since heat exchanger tube general thickness is relatively thin, the phenomenon that generation using welding plugging by weld seam drawing crack, and some materials
Matter can not be welded (such as titanium tube)；Although the method for squeezing into taper plug does not have to welding, it is only applicable to low pressure heat exchanger,
And plug is easy to fall off, and causes secondary leakage.
Utility model content
For the utility model in order to overcome poor sealing effect existing in the prior art, deficiency complicated for operation provides one
Kind structure is simple, easy to use, can be improved working efficiency and sealing effect, and versatile quickly blocks up for pipe heat exchanger
The sealing device of leakage.
To achieve the goals above, the utility model uses following technical scheme:
A kind of sealing device for pipe heat exchanger fast blockage, including stretching screw, one end of the stretching screw
Equipped with n expansion-head, the other end of stretching screw is equipped with tightening nut, is equipped with outer layer covers object outside each expansion-head, outside
Metal backup, the first gasket, gland and the second gasket are successively arranged between layer wrappage and tightening nut；Metal backup and outer
Layer wrappage connection, the second gasket are connect with tightening nut.
The outer layer covers object, stretching screw and metal backup of the utility model are integrally formed, will when carrying out plugging operation
The utility model is put into heat exchanger tube, screws tightening nut, and turnbuckle stretches, and fully supports the expansion of outer layer covers object in heat exchanger tube
Wall, the first gasket compress tube end, realize fast blockage.
Preferably, the metal backup is matched with the inner wall of heat exchanger tube, the maximum width of the metal backup and outer
The maximum width of layer wrappage is equal, and the maximum width of the first gasket is greater than the maximum width of metal backup, and the first gasket is most
Big width is less than the maximum width of gland, and the maximum width of the second gasket is greater than the maximum width of tightening nut.
Preferably, the maximum width of the first gasket is greater than the internal diameter of heat exchanger tube.
Preferably, the outer layer covers object is equipped with several anti-skid chequers, it is capable of increasing outer layer covers object and heat exchanger tube
Frictional force between inner wall.
Preferably, outer layer covers object and the first gasket are all made of rubber material and are made.
Preferably, second gasket is spring shim.
Preferably, the value of n is 1 to 5, the number for increasing expansion-head can increase contact area, improve leak preventing effect.
Therefore, easy to use the utility model has the following beneficial effects: the utility model overall structure is simple, it is general
Property is strong；Using heat transfer tube wall is fully supported after the expansion of outer layer covers object, it can be realized fast blockage sealing, improve working efficiency and close
Seal effect.
Detailed description of the invention
Fig. 1 is a kind of cross-sectional view of the utility model；
Fig. 2 is a kind of installation diagram of the utility model；
Fig. 3 is a kind of structural schematic diagram completed after leak stopping of the utility model.
In figure: stretching screw 1, outer layer covers object 2, metal backup 3, the first gasket 4, gland 5, the second gasket 6, heat exchanger tube
7, expansion-head 11, tightening nut 12.
Specific embodiment
The utility model is described further with specific embodiment with reference to the accompanying drawing:
Embodiment as shown in Figure 1 is a kind of sealing device for pipe heat exchanger fast blockage, including stretching screw
1, one end of the stretching screw is equipped with 2 expansion-heads 11, and the other end of stretching screw is equipped with tightening nut 12, each expansion-head
Outside is equipped with outer layer covers object 2, be successively arranged between outer layer covers object and tightening nut metal backup 3, the first gasket 4,
Gland 5 and the second gasket 6；Metal backup is connect with outer layer covers object, and the second gasket is connect with tightening nut；The outer layer covers
Object is equipped with several anti-skid chequers；Outer layer covers object and the first gasket are all made of rubber material and are made；Second gasket is bullet
Spring gasket.
Wherein, the maximum width of metal backup is equal with the maximum width of outer layer covers object, the maximum width of the first gasket
Greater than the internal diameter of heat exchanger tube, the maximum width of the first gasket is less than the maximum width of gland, and the maximum width of the second gasket is greater than
The maximum width of tightening nut.
As shown in Fig. 2, outer layer covers object, stretching screw and metal backup are integrally formed, there are one with the internal diameter of heat exchanger tube 7
Fixed gap when installation, the utility model is integrally filled in heat exchanger tube, rubber sheet gasket, spring shim, is successively placed on gland
On the outside of heat exchanger tube, tightening nut is spun on turnbuckle.
As shown in figure 3, stretching screw stretches after screwing tightening nut, the expansion of outer layer covers object is made to fully support the interior of heat exchanger tube
Wall achievees the effect that fast blockage seals using the rubber material of outer layer covers object and the frictional force of heat transfer tube wall；Positioned at changing
The first gasket on the outside of heat pipe compresses, it is ensured that end does not leak；The conical surface of the stretching screw close to the expansion-head of tightening nut side
It is in contact with metal backup, entire utility model is made to reach certain rigidity, maintain the stability of system.
