Specific embodiment
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, to specific embodiment, structure, feature and its effect is proposed according to the present invention, detailed description is as follows.
Fig. 2 is referred to, the first embodiment of the present invention provides a kind of chemical industry fluid conveying leakproof double-jacket tube, including：It is interior
Pipe 1 and the transparent pipe 2 being set in outside the inner tube 1.
Fig. 3, Fig. 4 are referred to, discoloration paper tape 3 is wound with outside inner tube 1, which includes paper substrates 31 and attachment
Off-color material 32 on the paper substrates 31, the off-color material 32 are used for the chemical industry fluid of the contact leakage when inner tube 1 is revealed
Change color instruction leakage position.Off-color material 32 is the anhydrous cupric sulfate being attached to outside paper substrates 31, and chemical industry fluid includes
Water.The paper tape 3 that changes colour can also be PH test paper.Inner tube 1 is made of PVC.
Fig. 5, Fig. 6 are referred to, more piece transparent pipe 2 is arranged with outside inner tube 1.2 end of transparent pipe and inner tube 1 are tightly connected.Thoroughly
