Description
Technical field
The present invention relates to the sealing device of ductile iron pipe cement mortar Centrifugal smearing technical field, particularly coated lining with inserting
Mouth plug.
Background technology
At present, conventional coated lining socket plug is general steel, because ductile iron pipe socket end cut is uneven and ellipse
Circle problem, easily causes steel plug not tight with the laminating of socket end, causes material leakage, additionally at Centrifugal smearing in centrifugal process
Complete, during dismounting coated lining plug, the cement mortar with plug contact site can be caused to be fallen by band, cause liner misrun, need to pass through
Repair, and the intensity repaired cannot arrive the intensity that centrifugal force produces, and easily causes and comes off.
Summary of the invention
The goal of the invention of the present invention is that solving ductile iron pipe Centrifugal smearing process socket material leakage, socket end misrun occurs
Etc. problem, and provide a kind of coated lining socket plug.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of coated lining socket plug of the present invention, it includes: fixing plug, sealing plate, seal plug, bolt and spiral shell
Mother, wherein: sealing plate is disposed vertically, sealing plate, with the end contact of the socket end of ductile iron pipe, fixes plug and seal plug
Head by screw bolt and nut be fixed on sealing plate both sides, seal plug has an annular seal space towards sealing plate opening, sealing
Chamber, equipped with Inflated rubber tape, withstands on sealing plate after Inflated rubber tape inflation, and fixing plug has a closed chamber towards under shed, close
Envelope room, equipped with Inflated rubber tape, withstands on the front of the socket end of ductile iron pipe after Inflated rubber tape inflation；
A kind of coated lining socket plug of the present invention, wherein: described sealing plate front end be also equipped with seal header board, before sealing
The hardness of plate less than sealing plate hardness, seal the end contact of the socket end of header board and ductile iron pipe；
A kind of coated lining socket plug of the present invention, wherein: be also equipped with bolt sleeve on bolt, the length of bolt sleeve is used for adjusting
The fixing distance between plug and seal plug of joint；
A kind of coated lining socket plug of the present invention, wherein: described nut is 2；
A kind of coated lining socket plug of the present invention, wherein: being shaped as of described Inflated rubber tape is U-shaped.
Mortar material leakage when the coated lining socket plug of the present invention can well solve ductile iron pipe Centrifugal smearing is asked
Topic, and coated lining complete after rigidity plug in demolishing process because the most separately causing cement with the cement mortar of molding
The problem that mortar band falls.The present invention is easy to operate, can well solve the socket that ductile iron pipe Centrifugal smearing process occurs
Material leakage, the problem such as socket end misrun, improves the presentation quality of ductile iron pipe product.

Detailed description of the invention
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.
As it is shown in figure 1, the coated lining of present invention socket plug: fixing plug 8, sealing plate 2, sealing header board 1, seal plug
3, bolt sleeve 6, bolt 5 and nut 7, sealing plate 2 is disposed vertically, and seals header board 1 and is contained in the front end of sealing plate 2, seals header board 1
Hardness, less than the hardness of sealing plate 2, seals the end contact of header board 1 and the socket end 10 of ductile iron pipe, sealing plate 2 and sealing
Both header boards 1 are sticked together by sticky stuff.Wherein sealing plate 2 plays a supportive role, and prevents deformation.Seal header board 1 close
Envelope effect, it is ensured that sealing plate fits tightly with ductile iron pipe socket end 10, it is ensured that cement mortar 11 molding.Fixing plug 8 He
Seal plug 3 is fixed on the both sides of sealing plate 2 by bolt 5 and nut 7, and seal plug 3 has close towards sealing plate 2 opening
Envelope chamber 4, at annular seal space 4 equipped with Inflated rubber tape 12, withstands on sealing plate 2 after Inflated rubber tape 12 inflation, fixing plug 8 have one towards
The closed chamber 9 of under shed, at closed chamber 9 equipped with Inflated rubber tape 12, withstands on the socket of ductile iron pipe after Inflated rubber tape 12 inflation
The front of end 10, being shaped as of Inflated rubber tape 12 is U-shaped, and bolt 5 is also equipped with bolt sleeve 6, and the length of bolt sleeve 6 is used for regulating admittedly
Determine the distance between plug 8 and seal plug 3.Nut 7 is 2, is used for locking bolt 5.
First pass through manually or coated lining socket plug moved to above ductile iron pipe socket end 10 by other machinerys,
Sealing header board 1 and ductile iron pipe socket end 10 is made to leave certain gap.Then the Inflated rubber tape 12 in closed chamber 9 is passed through
Gases at high pressure, make fixing plug 8 be fixed in ductile iron pipe socket end 10, then the Inflated rubber tape 12 in annular seal space 4 are passed through
Gases at high pressure, make sealing header board 1 and ductile iron pipe socket end 10 fit tightly.Finally it is centrifuged coated lining cement mortar 11
Operation, after coated lining completes, releases Inflated rubber tape 12 mesohigh gas in annular seal space 4, makes sealing header board 1 insert with ductile iron pipe
Mouth end 10 end face separates, and then, is released by Inflated rubber tape 12 mesohigh gas in closed chamber 9, the coated lining socket plug of the present invention
Can be removed.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees right
Requirement, in the case of the spirit of the present invention, the present invention can make any type of amendment.
