Description

The pipe plugging part of adjustable interior outside dimension
Technical field
The present invention relates to the device for shutoff cable protection pipe, particularly relate to a kind of pipe plugging part that can regulate the adjustable interior outside dimension of outside dimension in closeouts.
Background technique
Along with the development of electric power, telecommunications industry and the needs of urban construction, cable laying is many changes under ground piping paving mode into by built on stilts paving mode.Because cable requires to install protective tube additional in laying; cable can form annular space through during cable protection pipe cable and protective tube; so; shutoff is carried out to cable protection pipe, sewage, harmful gas or foreign matters to be entered in pipe just become in power construction a basic demand without ignorance.
At present; on market, the special product of shutoff cable protection pipe is few; wherein imported product is expensive; the performance such as intensity, toughness of the plugging materials such as the cement of domestic employing, silk fiber crops or waterproof clay is poor again; to be easy to when circuit is energized because vibrations cause crack, add raceway often and the pipeline such as underground water supply and drainage, combustion gas, heating walk abreast or intersect, pipeline construction quality easily goes wrong; make pipeline be easy to occur infiltration, ooze the phenomenon of vapour.Also can form the situation of cable draw pit ponding, water filling underground transformer and distribution power station rainy season, bring difficulty not only to the staff of circuit homework and transformer and distribution power station, and be easy to cause the accident, even can cause power failure, cause unnecessary loss.
Claimant applies for before this and patented 200620160060.0 once disclosed a kind of elastic pipe plugging piece.This closeouts is made up of elastomer and inside and outside pressing plate, and elastomer and inside and outside pressing plate are symmetric type semicircular structure.The position corresponding at elastomer, inside and outside pressing plate has through hole, and bolt is connected with nut through through hole, elastomer, inside and outside pressing plate is connected together.During installation, fastening nut makes elastomer radial expansion reach sealing purpose.Although this closeouts has, structure is simple, good airproof performance, be convenient to advantages such as installing, effect is attractive in appearance.
But in the face of the kind of existing cable and protective conduit is varied; and cable is diversified especially with coordinating of pipeline in actual facility work; traditional closeouts can only adapt to a kind of pipeline and cable of size; special closeouts customized is needed before each shutoff; wherein different elastomers just needs different moulds from the making of pressing plate; considerably increase cost of production, waste time and energy, can not standardization be realized.
Summary of the invention
The object of this invention is to provide a kind of pipe plugging part of adjustable interior outside dimension, by being respectively equipped with interior expansion part and extending out part inside and outside basic part, only change in different size when difference changes basic part and expand part and extend out the shutoff that part realizes pipelines and cable.
The object of the invention is to be achieved through the following technical solutions:
