Furthermore, the inside sealing washer that is equipped with of ring channel, and the sealing washer is the perfluoroelastomer material, leakproofness when increasing two steel lining tetrafluoro pipes and connecting, and perfluoroelastomer has stronger corrosion resistance, prevents that the sealing washer from being corroded.
Furthermore, the trapezoid connecting strip is fixedly bonded with the inner walls of the first trapezoid-shaped groove and the second trapezoid-shaped groove through glue, the connection between the tetrafluoride pipe lining and the steel pipe can be enhanced through the trapezoid connecting strip, and the tetrafluoride pipe lining and the inner wall of the steel pipe are prevented from being separated under a negative pressure environment.
Furthermore, a plurality of annular reinforcing ribs are fixed on the outer side wall of the steel pipe at equal intervals, so that the compressive strength of the steel pipe body is improved.
Furthermore, the surfaces of the steel pipe and the annular reinforcing ribs are coated with anticorrosive coatings, so that the anticorrosive performance of the surface of the steel pipe is improved.
The utility model has the advantages that:
the utility model discloses when using, through setting up steel pipe and tetrafluoro pipe lining, tetrafluoro pipe lining passes through the fixed bonding of glue at the steel pipe inside wall, and the inside a plurality of reinforcing rings that inlay of tetrafluoro pipe lining, increase the intensity of tetrafluoro pipe lining, a plurality of first dovetail grooves and second dovetail groove have been seted up with steel pipe inside wall correspondence to tetrafluoro pipe lining lateral wall, first dovetail groove and the inside trapezoidal connecting strip that is equipped with jointly of second dovetail groove, thereby can strengthen steel pipe and tetrafluoro pipe lining through trapezoidal connecting strip and be connected, make this steel lining tetrafluoro pipe under negative pressure environment, tetrafluoro pipe lining can not break away from with the steel pipe, and then improve the life of this steel lining tetrafluoro pipe, secondly through all having seted up the ring channel in tetrafluoro pipe lining both sides, the inside sealing washer that is equipped with of ring channel, can improve the leakproofness of this steel lining tetrafluoro pipe when connecting.
