The flexible interface form is a lot, mainly contains the formula of slipping into (T type), mechanical type (K type), mechanical type (N type, S type), flange type etc.Wherein, T type and K type interface are mainly used in water supply line, and N type and S type are mainly used in steam line.Flexible interface good leak tightness, pliability and stretchability are good, and construction is rapidly simple, can slow down corrosion, but still can not avoid seepage, and especially in the winter time, because the additional stress that the temperature difference produces, the seepage situation of large-diameter pipe pipeline joint is very serious.In addition, because the uneven settlement that native water weight or garage's load cause also can cause the pipe joint seepage, the performance in the new pipeline of laying of this phenomenon is fairly obvious.And larger axis to the effect (like earthquake) situation under, above-mentioned interface, especially T type interface are easy to extract destruction.And the socket joint section of K type interface is very short, also extracts easily or bellmouth is broken mode of failure such as evil idea off with the fingers and thumb.S type interface behaves oneself best in the performance of above-mentioned interface, has certain anti-ability of extracting, and reason is that S type interface has increased rigid support circle and stopping lock ring on the basis of K type interface.
Summary of the invention
The objective of the invention is to solve above-mentioned pipe leakage safe and reliable intelligent leakage proof aqueduct interface is provided; Interface shape of the present invention provides the possible approach that overcomes the pipe joint seepage; Thereby reduce the pipeline water delivery loss, realized the intelligent self-repair function of pipeline.
For realizing the foregoing invention purpose; A kind of intelligent leakage proof aqueduct interface provided by the invention; Comprise bellmouth and socket, said bellmouth inwall is provided with groove, it is characterized in that also comprising cushion rubber; Said cushion rubber is the compound body that first rubber ring, hydro-expansive rubber putty sealing rod and second rubber ring are bonded successively; First rubber ring is the flexible glue of 50 ° ± 5 ° of shore hardnesses, and second cushion rubber is the ebonite of 88 ° ± 3 ° of shore hardnesses, and hydro-expansive rubber putty sealing rod is the rubber of 50 ° ± 5 ° of shore hardnesses; Both are General Purpose Rubber, should meet the regulation among " water and gas pipeline are with ductile iron pipe, pipe fitting and annex " (GB/T 13295-2208).Socket inserts in the bellmouth during use; Cushion rubber is embedded in the groove; First rubber ring is positioned at directly contact water delivery medium one side of bellmouth, and second rubber ring is positioned at bellmouth away from medium one side, and hydro-expansive rubber putty sealing rod is between first cushion rubber and second cushion rubber.
Among the present invention, said a kind of intelligent leakage proof aqueduct interface is T type interface or K type interface.
The invention has the advantages that: the expandable rubber that plays a crucial role can be expanded to more than 200% of volume after long-time the immersion in water, and can be expanded to 150% of volume in 24 hours.In case seepage takes place, hydro-expansive rubber will expand, be expanded to by after the tube wall constraint, and the circumferential pressure that generation is very big, thus stop water to continue to ooze out from the cushion rubber slit, thus realize intelligent leakage proof function.
