Buried tank will all be updated to double-layer tank or completes antiseepage pond to set before the end of the year 2017, comprehensive consideration, for it is a large amount of at present just
It is economy efficiently method the most that the individual layer oil tank being in during one's term of military service, which be lined transformation, still, in the prior art through interior
The oil storage cylinder of steel of liningization transformation, long construction period, construction technology is cumbersome, and improvement cost is high, and antiseep effect is undesirable.
Utility model content
The purpose of this utility model be just to provide that a kind of with short production cycle, manufacturing cost is low and good seepage-proof property it is new
FRP liner cylinder of steels.
To achieve the above object, technical scheme is used by the utility model：
A kind of new type FRP liner cylinder of steel, by the cylinder of steel of outer layer, FRP liners tank on its interior and be arranged at both it
Between vacuum leak hunting unit form, it is characterised in that：The vacuum leak hunting unit includes being bonded rubber with the cylinder of steel inner wall sealing
Capsule body, the closed-gap layer formed by annular knurl aluminium foil, the closed-gap are set between rubber utricule and FRP the liner tank
Layer is connected with manhole at the top of cylinder of steel by detecting pipeline with vavuum pump, and pressure gauge is set on the detection pipeline.
Forming a kind of additional technical feature of above-mentioned new type FRP liner cylinder of steel also includes：
--- surface is uniformly arranged the projection of multiple hemispheres or round estrade in the rubber bag tank body；

--- the inwall of the FRP liners tank sets antistatic backing, the conductive earthing mechanism of the antistatic backing and abhiseca
Connection；
--- the antistatic backing is the epoxy coating containing SiC, and thickness is 0.6 to 1.2mm.
A kind of new type FRP liner cylinder of steel provided by the utility model compared with prior art, has advantages below：Its
One, because the FRP liners cylinder of steel by the cylinder of steel of outer layer, FRP liners tank on its interior and is arranged at vacuum between the two
Unit of hunting leak is formed, and liner transformation is convenient, has the characteristics of simple in construction；Second, the vacuum leak hunting due to the FRP liner cylinder of steels
Unit includes being bonded rubber utricule with cylinder of steel inner wall sealing, sets between rubber utricule and FRP liner tanks and is formed by annular knurl aluminium foil
Closed-gap layer, outer layer cylinder of steel and FRP liners tank isolation it is more perfect, anti-leak result is more preferable；Third, the FRP inner lining steels
Surface is uniformly arranged the projection of multiple hemispheres or round estrade in the rubber bag tank body of tank, increases the thickness of closed-gap layer, expands
The space in intermediate layer has been filled, has been easily installed leakage detection apparatus.
