Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The embodiment of the invention discloses a kind of special-shaped pipeline crossing seal part, risen Guyuan reason using pull bar, selection is split type
Design, not only installation is simple, and solves the sealing problem of shape tube hole through walls, realizes the perfect close of shape tube and hole
Envelope.
The present invention utilizes the elastomeric feature of material, using the pressure cooperation of dormant bolt, pressure plare and fastening plates, makes swollen
Swollen modules A and expansion module B is expanded, so as to reach the effect combined closely with hole inwall；It is interposed in bulging die simultaneously
Fireproof seal daub between block A and expansion module B, the effect being under pressure, expansion module inwall and abnormal shape is filled in automatically
In the Anomalistic space formed between tube wall, good sealing effectiveness is played.
The invention provides two kinds of application schemes：
The first：When wearing every hole aperture more specification and wall feed-through pipeline more specification, the present invention provides pull bar and risen admittedly
Sealed product.The sealing of such a form uses split-type design, and installation is simple, cost is relatively low；Using the elastomeric feature of the body that rises,
Using pressure caused by bolt, pressure plare, fastening plates, the body that makes to rise expands, and reaches the mesh be close to Dong Bi and wear pipe road
's；Be interposed in the lute in rise between body A and the body B that rises simultaneously, the effect being under pressure, be filled in automatically rise internal wall with it is different
In the space of type pipe, good sealing function is played, as shown in Figure 1.
Second：When wear every hole aperture it is irregular or wear pipe road it is irregular when, the present invention provides and carries reducing
The pull bar of delamination rises solid sealed product.During actual use, the internal diameter size of hole is first confirmd that, outer reducing is shelled
Layer delamination, to facilitate insertion hole, while confirm the outside dimension for the pipeline that needs pass through, interior reducing delamination delamination reaches
To preferable parcel effect；Product is then filled in into hole, screws dormant bolt, expands expansion module, is fixed in hole,
And the lute in effect of being stressed is automatic to overflow, and fills into the gap inside shape tube and expansion module, reaches perfect
Sealing, as shown in Figure 2.
It is a kind of special-shaped pipeline crossing seal part provided by the invention to refer to relevant drawings, including：Dormant bolt 1；According to
It is secondary through the pressure plare 2 of dormant bolt 1, expansion module A3, expansion module B4 and fastening plates 5；Wherein expansion module A3 and swollen
Be provided with interior reducing delamination 6 on the inside of swollen module B4, be provided with the outside of expansion module A3 and expansion module B4 it is outer can
Reducing delamination 7；The fireproof seal daub 8 being interposed between expansion module A3 and expansion module B4；Special-shaped pipeline crossing seal part
Expansion module A3 and expansion module B4 are expanded by the pressure cooperation between dormant bolt 1, pressing plate plate 2, fastening plates 5,
And the effect that fireproof seal daub 8 is under pressure is filled in shape between expansion module A3, expansion module B4 and special-shaped tube wall automatically
Into Anomalistic space in, complete the sealing of shape tube and hole.
In order to further optimize above-mentioned technical proposal, expansion module A3 and expansion module B4 using pouring technology once into
Type, and expansion module A3 and expansion module B4 material are ethylene propylene diene rubber or silicone rubber material, ethylene propylene diene rubber
It is the copolymer of ethene, propylene and a small amount of non-conjugated diene hydrocarbon, is one kind of EP rubbers, is represented with EPDM, because of its main chain
It is made up of chemically stable saturated hydrocarbons, unsaturated double-bond is only contained in side chain, therefore its resistance to ozone, heat-resisting, weather-proof etc. are resistance to old
Change excellent performance, can be widely used for automobile component, building water-proof material, electric wire and cable jacket, heat-resistant rubber hose, adhesive tape, automobile
The fields such as seal；Silicon rubber refers to that main chain is alternately made up of silicon and oxygen atom, and two organic groups are generally connected with silicon atom
Rubber.Common silicon rubber is mainly made up of the silica chain link containing methyl and a small amount of vinyl.The introducing of phenyl can improve silicon
The introducing of the high- and low-temperature resistance performance of rubber, trifluoro propyl and cyano group can then improve the heatproof and oil resistance of silicon rubber.Silicon rubber
Resistance to low temperature is good, typically remains to work at -55 DEG C.After introducing phenyl, reachable -73 DEG C.The heat resistance of silicon rubber
It is very prominent, at 180 DEG C can long-term work, a little higher than 200 DEG C can also bear several weeks or longer time it is still flexible, be instantaneously resistant to
More than 300 DEG C of high temperature.The good permeability of silicon rubber, OTR oxygen transmission rate are highest in synthetic polymer.The master of silicon rubber
Characteristic is wanted to have (1) high-temperature behavior.Under hot environment more than 200 DEG C, silicon rubber remains to keep certain pliability, resilience
And case hardness, and mechanical property is without significant change.(2) cryogenic property, the glass transition temperature of silicon rubber are generally -70~-50
DEG C, reachable -100 DEG C of special formulation, show its low temperature performance excellent.(3) weatherability, Si-O-Si keys are to oxygen, ozone in silicon rubber
And ultraviolet etc. is sufficiently stable, in the case where being not added with any additive, just there is excellent weatherability.(4) electric property.Silicon
Rubber has excellent insulating properties, and corona resistance and arc resistance are also very good.(5) physical and mechanical properties.In 150 DEG C of height
Gently in a low temperature of -50 DEG C, its physical and mechanical properties is better than general purpose rubber.(6) oil resistant and chemical agents.Usual silicone rubber has
There are medium oil resistant, solvent resistance.(7) Gas permeability.Silicon rubber is to gas such as air, nitrogen, oxygen, carbon dioxide at room temperature
The gas permeability of body is higher by 30-50 times than natural rubber.(8) physiological inertia.Silicon rubber is nontoxic, tasteless, odorless.
In order to further optimize above-mentioned technical proposal, interior reducing delamination 6 and outer reducing delamination 7 use EPDM
Material or silastic material, wherein interior reducing delamination 6 can peel corresponding rubber layer off to adapt to according to different line sizes
Outer diameter tube；Outer reducing delamination 7 can peel corresponding rubber layer off according to different dimensions of opening and adapt to hole internal diameter.
In order to further optimize above-mentioned technical proposal, expansion module B4 is provided with guide pile, and fireproof seal daub 8 is attached to
On the guide pile.
In order to further optimize above-mentioned technical proposal, the technical indicator of fireproof seal daub 8 is：
Outward appearance：Plastic solid, there is certain pliability；
Density：2.0×103kg/m3；
Water resistance：d：＞ 3 is without swelling and cracking；
Oil resistivity：d：＞ 3 is without swelling and cracking；
Corrosivity：d：＞ 7 is corrosion-free；
Fire endurance：＞ 180min；
The solid technical indicator of the speed of fireproof seal daub 8：
