Technical field
This utility model is related to communication pipe, power pipe, in particular it relates to a kind of duct closing type device.
Background technology
In communication and power domain, substantial amounts of optical cable and cable are placed in underground piping by cloth.Each city has thousands of
Underground piping network as kilometers up to ten thousand.Underground piping is generally all that one section of one section of ground connects together, average per segment pipe
Length less than 100 meters, here it is why when we are walked on the street in city, the reason for always can be appreciated that countless well lids.
Below well lid, people's well is commonly called as, is exactly the end and the beginning of another segment pipe of a segment pipe, the depth of people's well is generally 1 to 5
Rice.People's well is typically a space for having several square meters, puts for accommodating workman and carrying out wearing for cable.
In the region of many water, before people's opening well lid is prepared to enter into operation, it will usually find to have filled water in well, especially
It is in rainy season.Then, workman starts to draw water, but finds that water is always taken out and do not do, because those communications or power pipe are all logical
These well connections are crossed, the water in surrounding well can continue to flow into the well taken out by pipeline.Therefore, constructed according to concerned countries
Specification, pipe end needs to be blocked.Another benefit of closure is that the things such as rubbish, mouse will not enter pipeline and cause
There is blocking when laying cable, mouse can also sting bad cable.
The technology tradition of pipe plugging is hard closure or rigidity closure, i.e., can be solidified using cement, polyurethane, stifled mud etc.
Material, these materials respectively have drawback because expanding with heat and contract with cold, especially below the road with vibrant characteristic easily cracking, leakage
Water.And air seal bag technique is especially suitable for the seal for pipe joints in vibration environment.The air seal bag of strip is wound on cable
And duct wall between, the positive and negative of hermetic bag all posts waterproof adhesive tape, so as to allow hermetic bag and duct wall with the cable for wrapping up more
Plus laminating, improve sealing effectiveness.By being filled with gases at high pressure so that hermetic bag expands and blocking pipe end.
This flexible blockage technology of air seal bag has obtained tremendous development in recent years, but there is problems with：

Specific embodiment
This utility model is described in detail with reference to specific embodiment.Following examples will be helpful to this area
Technical staff further understands this utility model, but does not limit this utility model in any form.It should be pointed out that to ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, some deformations and improvement can also be made.
These belong to protection domain of the present utility model.
The duct closing type device that this utility model is provided, including hermetic bag；Wherein, it is provided with for filling in the hermetic bag
The air valve of deflation；The hermetic bag is made using plastimets.
The air valve includes elastic vent plug and valve seat；Wherein, described valve seat one end connects the hermetic bag；The valve seat sets
It is equipped with the truncated cone-shaped chamber matched with the elastic vent plug；The hermetic bag is elongated.
The elastic vent plug is arranged on the truncated cone-shaped intracavity；The small end in the outer end correspondence truncated cone-shaped chamber of the valve seat.
The shape of built-in elastic vent plug is coincide with truncated cone-shaped chamber, and after inflation is finished, hermetic bag internal high-pressure gas can be pushed away
Dynamic elasticity vent plug is moved out, and because more outward, cavity is less, elastic vent plug is just extruded and clogs truncated cone-shaped chamber, so as to reach
To sealing effectiveness.
The air valve body is arranged when the air valve is built-in air valve, i.e. the main body of air valve in hermetic bag, in such as Fig. 3
Shown in (a).The air-tightness of hermetic bag is improved.Because the truncated cone-shaped plastics cavity wall of air valve has small breathability, passes through
Whole cavity is made in hermetic bag, this part gas leakage factor can be eliminated, because the gas spilt by wall is still existed
In hermetic bag；Protection to air valve this key device is improved, exposed after all to be easily damaged outside.
When the air valve is external air valve, i.e. outside hermetic bag, (b) is shown in such as Fig. 3 for the main body of air valve.So as to manufacture
When be easier, production cost can be lower.
The hermetic bag adopts aluminum-plastic composite membrane；The aluminum-plastic composite membrane is composited using aluminium film and Multilayer plastic film.
Aluminum-plastic composite membrane is generally at 3 to 7 layers, it is also possible to more, has higher intensity relative to fine aluminium thin film, more resistant to corruption
Erosion, more suitable for underground environment, composite plastic film can play a part of protect aluminium film.Meanwhile, aluminum-plastic composite membrane has more toughness,
Can repeatedly fold and keep intensity, and the folding of fine aluminium thin film several times afterwards can be damaged in burst.For with charging-discharging function,
And need for reusable hermetic bag, aluminum-plastic composite membrane is optimal material.By the selection to film material, can be with
So that hermetic bag has anticorrosion, fire prevention, anti-wear and improve the functions such as intensity, toughness, air-tightness.Taken using aluminum-plastic composite membrane
For soft metal or aluminium film, so as to service life and intensity of the hermetic bag in underground can be greatly improved.
The vent plug is made using fluorubber, ethylene propylene diene rubber or butyl rubber.
Rubber is a kind of elastomer of suitable underground environment.Underground environment is more complicated, and there is difference different regions again；Institute
There must be a very high chemical resistance with, all material, and keep excellent elastic properties of materials and air-tightness for a long time.Through resistance to material
The aggregate balancing of chemical, aging characteristics, material air-tightness and elastic properties of materials this several key property, detection and assess, and
Substantial amounts of engineering test.It is preferred that fluorubber, ethylene propylene diene rubber and butyl rubber are used as rubber plug material, it is close so as to ensure that
Long-term air-tightness of the envelope in underground environment.
The valve seat adopts made of plastic.
Vent plug is limited in valve seat made by plastics made by rubber.Rubber is also in a broad sense a kind of plastics, but
It is different from plastics for narrow sense implication, i.e. rubber herein.The valve seat is fixed on aluminum-plastic composite membrane bag.The valve seat of plastics and modeling
The bond strength of material composite membrane is higher, and structural stability and air-tightness are all relatively good.As shown in Figure 2.
The surface of the hermetic bag covers a sealed film.
The plastic foil adopts polyester, nylon, polrvinyl chloride, polyethylene, polypropylene, rubber, polyurethane, ethyl ester, fragrance
The combination in any of polyamide, tripolycyanamide, polyphenylene sulfide, politef and Kynoar or any one make.
The bottom of the valve seat is provided with ventilative collet.
Preferably, valve seat collet has breathability.Collet can only be transported in truncated cone-shaped cavity for limiting rubber vent plug
Dynamic, during inflation, vent plug moves to collet under external pressure promotion, and now collet must have breathability, allow extraneous gas to continue
It is filled with hermetic bag.
Specific embodiment of the utility model is described above.It is to be appreciated that this utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can within the scope of the claims make various modifications or modification,
This has no effect on flesh and blood of the present utility model.
