Description
Technical field
It the utility model is related to the cable inflatable duct closing type device suitable for Stranded cable.
Background technology
Cable channel closure is critically important, because buried cable, because management is inconvenient, cable is often soaked by rainwater, or always
Damaged by rats is broken, and situations such as causing to leak electricity, power off, is influenceed greatly.Even also there is pipeline flow in some, increases artificial well and draws water
The trouble dredged and time, reduce operating efficiency.Present cable inflatable duct closing type device enters mainly for single cable
Row sealing, if Stranded cable is because airbag is impermeable between cable, therefore it can also form gap between cable and make
Fail into sealing.
Utility model content
The purpose of this utility model is to provide the cable inflatable duct closing type device suitable for Stranded cable, Neng Gouyou
Effect solves the problems, such as that existing plugging device is bad to Stranded cable sealing property.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：Suitable for multiply electricity
The cable inflatable duct closing type device of cable, include the airbag of banding, post diaphragm seal on the outside of the airbag, on the airbag
Provided with inflation inlet, silica gel is posted on the inside of the airbag, the silica gel leaves gap into bulk between every block of silica gel.
Every piece of silica gel 1cm × 1cm, the spacing between adjacent silica gel is 0.5cm；Because silica gel will be as far as possible thick and wants soft
Penetrate between cable well, be not easy blocking so silica gel is too small, silica gel is too very much not readily permeable to enter, for adjacent silica gel it
Between spacing too conference influence sealing, too small silica gel, which is crowded together, to be not easy to penetrate between cable.
Air valve is provided with the inflation inlet；Advantageously reduce production cost.
The air valve includes valve body and flap, and the valve body includes air inlet and valve chamber, and the flap is rotatably connected on valve
Interior, when air valve is inflated, flap is towards rotating in airbag；When air valve is non-aerating, flap touch air inlet；It is simple in construction again
The air valve structure of preferable sealing effect can be played.
The porch switching of the inflation inlet has soft valve plug, and the soft valve plug is provided with passage, institute centrally along axis
Stating soft valve plug includes block and cock body, and the block diameter is more than inflation inlet diameter, the cock body diameter and air inlet diameter
Equal, the cock body length is more than air inlet length；Can be closed inflation inlet by soft valve plug prevents dirt from entering inflation
Mouthful, when needing to deflate, flap top can be opened, it is easy to operation.
Compared with prior art, the utility model has the advantages that：The present apparatus posts silica gel on the inside of airbag, and silica gel into
Bulk leaves gap, and when wrapping up multi-cable, silica gel can be penetrated into the gap between cable, so as to preferably play
The effect of sealing, prevent water, dirt or animal from entering in pipeline, the safety of protective conduit.

Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings.Below with reference to
The embodiment of accompanying drawing description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
In the description of the invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width ",
The instruction such as " thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer "
Orientation or position relationship are based on orientation shown in the drawings or position relationship, are for only for ease of the description present invention and simplification is retouched
State, rather than instruction or imply signified device or element there must be specific orientation, with specific azimuth configuration and operation,
Therefore it is not considered as limiting the invention.
In addition, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint relative importance
Or the implicit quantity for indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can be expressed or
Implicitly include at least one this feature.In the description of the invention, " multiple " are meant that at least two, such as two, three
It is individual etc., unless otherwise specifically defined.
In the present invention, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " fixation " etc.
Term should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integrally；Can be that machinery connects
Connect or electrically connect or can communicate each other；Can be joined directly together, can also be indirectly connected by intermediary, can be with
It is connection or the interaction relationship of two elements of two element internals, is limited unless otherwise clear and definite.For this area
For those of ordinary skill, the concrete meaning of above-mentioned term in the present invention can be understood as the case may be.
Refering to the reality that Fig. 1, Fig. 2, Fig. 3 are the cable inflatable duct closing type device that the utility model is applied to Stranded cable
Example is applied, wherein Fig. 3 is unaerated state, suitable for the cable inflatable duct closing type device of Stranded cable, includes the gas of banding
Bag 1, airbag 1 is synthesized using alloying metal and multi-layer nano high polymer material, and diaphragm seal 2 is posted in the outside of the airbag 1,
The airbag 1 is provided with inflation inlet 3, and air valve, in order to preferably be sealed to Stranded cable, airbag 1 are provided with inflation inlet 3
Silica gel 4 is posted in inner side, and the selection of silica gel 4 is tried one's best soft grade, and silica gel 4 is embarked on journey or into column distribution, two adjacent row or two
Row interlock, every piece of silica gel 41cm × 1cm, leave gap between adjacent silica gel 4, and the spacing between adjacent silica gel 4 is 0.5cm.
The application method of cable inflatable duct closing type device, first by inner-walls of duct wiped clean, while pipeline will be penetrated
The outer surface of the interior stranded cable near the pipeline opening also wiped clean, is rolled at least one circle outside Stranded cable by airbag 1, fills
Airbag 1 is filled in cable channel towards pipeline outside, passes through flexible pipe and insert inflation inlet 3, flexible pipe other end external gas by gas port 3
Source is inflated to airbag 1, silica gel 4 is squeezed into the gap between cable, by whole seal for pipe joints.
Air valve includes valve body 6 and flap 7, and the valve body 6 includes air inlet 8 and valve chamber 9, and the flap 7 is rotatably connected on
In valve chamber 9, when air valve is inflated, flap 7 rotates towards airbag 1 is interior；The rotation connection of flap and valve chamber inwall, which can use, to be turned round
Spring or flap are integrally manufactured with valve chamber inwall and use elastic material, and elastic material can be rubber or flexible plastic,
Flap energy self-return is blocked so after inflation, due to being filled with gas in airbag 1, the pressure in airbag 1
Be higher than outer, so when air valve is non-aerating, the pressure in airbag adds the self-return of flap so that flap 7 touch into
Gas port 8, air inlet 8 is closed.
As shown in Figure 4, Figure 5, in order to prevent dirt from being blocked to inflation inlet 3, the replacing of later stage cable is had influence on, inflation inlet 3
