Specific embodiment
To make the purpose of the present invention, technical solution and advantage are clearer, will carry out below to technical solution of the present invention
Detailed description.Obviously, described embodiment is only invention a part of the embodiment, rather than comprehensive embodiment.It is based on
The embodiment of the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment belongs to the range that the present invention is protected.
Band as shown in Figure 1, for the installation of hot-water heating facility, including base layer 1 and setting are on 1 back side of base layer
Expanding layer 2, it is inflatable that expanding layer 2 meets liquid.Expanding layer 2 can be used the modes such as spraying or brush or bonding and base layer 1 be arranged in
The back side, the back side refers to that base layer 1 is horizontal positioned, and the upper back side is lower for front.Expanding layer 2 is to utilize expanding layer 2 and pipeline
After middle solution contact, it can expand, increase the thickness of band to form seal isolation band, in hot-water heating pipeline installation process
In, for example, the docking of pipeline, using threeway or four-way or main pipe and branch pipe or standpipe etc. dock with installation, need at docking close
Envelope processing winds band at pipeline joint and is being installed.Seal isolation band specifically refers to, and band is wrapped on pipeline
After installation, in the long-term use process, after the liquid in pipeline is contacted with band, the band expansion that can make, with pipe
The Squeezing ground on road is higher, so that the liquid in pipeline be avoided the phenomenon that permeating or leaking occur.Expanding layer 2 can be used in pipeline
Liquid compatible and expanding layer can be made deformation occurs, for example, high-molecular compound or polymer composite etc..
By the setting expanding layer on 1 back side of base layer, expanding layer 2 is met liquid and be may expand, by the band after expansion
It is wrapped on hot-water heating facility, for example, the water lines at threeway position connect, using preceding by band water-soaked or immersion, leaching
Band after expansion is then wrapped in pipeline so that band integral thickness becomes large-sized by wet or 2 meeting of expanding layer after impregnating
It is upper to be installed with threeway, cause the leakproofness at pipeline threeway position to be promoted, moreover, in long-term pipeline use process
In, the liquid in pipeline touches band, and expansion can be made to survey expansion, and the gap between sealing and pipeline is formed good
Band is sealed off, to prevent the liquid in pipeline from oozing out.
As optional embodiment, expanding layer 2 is aqueous expanding layer, aqueous expanding layer water-swellable, in hot-water heating pipeline
Most cases be using water as medium, aqueous expanding layer can be water-swellable water-stop glue or bentonite composite material layer or
Montmorillonite composite material layer or the expandable high molecular material of other chance water etc., preferably bentonite composite material layer or
Montmorillonite composite material layer, economic cost is low, and good water-proof effect, is easy to be sprayed on 1 back side of base layer.Water expansion stops
Glue can be the super sealing material PJ220 and PJ400 of water-swellable water-stop glue, and the sealing material excellent as application property is that water is swollen
Swollen one-pack-type sealant.One hardened own vol expansion, filling sky after reforming into the good rubber elastomer of restoration, immersion
Gap plays certain water-stagnating effect.Montmorillonite is also known as montmorillonite, montmorillonite, and montmorillonite is the aqueous aluminium silicon superfine by particle
The layer mineral that hydrochlorate is constituted, molecule (Na, Ca) 0.33 (Al, Mg) 2 [Si4O10] (OH) 2nH2O, centre are alumina octahedral
Body is up and down the clay mineral of three-layer tablet shape structure composed by oxygen-octahedron, crystal structure interlayer is aqueous and some friendships
Cation is changed, there is higher ion exchange capacity, water swelling ability with higher.Montmorillonite composite material is existing skill
Montmorillonite composite material is effectively applied in hot-water heating field by art, the present inventor, avoids in pipeline going out for infiltration or leakage phenomenon
It is existing, and economic cost is substantially reduced, also, resistance to compression antiageing effect is obvious.
As optional embodiment, base layer 1 is layer of nonwoven material.Non-woven fabrics is by including chemical fibre and plant
Fiber etc. is made in wet process or dry method paper machine under conditions of using water or air as suspension media, though for cloth and without spinning
It knits therefore is called non-woven fabrics.It is acted on first is that cost is low；Second is that with montmorillonite composite material or bentonite composite material
Layer is easy to combine, industrial easily fabricated.
As optional embodiment, the front of base layer 1 is provided with waterproof layer 3.The effect of waterproof layer 3 is first is that improve
The positive impermeable effect of base layer 1；Second is that be easy to expanding layer 2 sufficiently with the media contact in pipeline, formed sealing every
From band.
As optional embodiment, corresponding position interval setting tearing line 10, is used on base layer 1 and waterproof layer 3
When the intumescent material for being easy to divide, such as when montmorillonite composite material layer, position only can be corresponded on base layer 1 and waterproof layer 3
Tearing line 10 is installed, tearing line 10 is non-porous tearing line, is made in industrial manufacturing process of the technique of compacting.And or
It is being respectively provided with tearing line 10 in base layer 1, expanding layer 2 and 3 corresponding position of waterproof layer, the effect of tearing line 10 is to be easy to band
Segmentation, when sealing at screw thread sealing or pipeline joint, the size of caliber is national standard, and the circle number quantity for needing to wind is generally
Be it is fixed, tearing line 10 setting distance be 10-30cm, for the sealed connection of different facility or pipeline, can be set to specially
With the band of model, increase the convenience used.
On the other hand the utility model provides a kind of sealing volume, including ontology 4 be wrapped on ontology 4 such as any of the above
One band.It is set to the structure integrally sold, ontology 4 is the setting of " I " fonts barrel configuration, Classical adhesive tape
Or " I " fonts barrel configuration used by raw material band, band are wrapped in I-shaped slot 5.
Further, band one end is fixed in I-shaped slot 5, and the other end is successively wound around I-shaped slot.
The utility model is mainly used on pipe fitting screw thread, for example, the screw thread in hot-water heating engineering seals, in use, by whole
Volume or part stand 2-5 minutes after impregnating 4-8 seconds in water and can be used, in use, by expansion level wrapping wire button winding 2-4 circle, and
So that band edge slightly exceeds tube head, then in the integral installation for carrying out pipeline, the beneficial effect using montmorillonite composite material layer is
Anti-aging, resistance to compression and sealing effect are good, moreover, manufacturing cost is cheap and environmentally friendly.
Upper described, the only specific embodiment of the invention, but the protection scope of innovation and creation is not limited to
This, anyone skilled in the art can readily occur in variation or replace in the technical scope that innovation and creation disclose
It changes, should be covered by the protection scope of the present invention.Therefore, the protection scope of the invention should be with appended claims
Subject to protection scope.
