Pass through above-mentioned technical proposal, 1, the utility model is carried out in the usual body to the defeated of gas or liquid Send, due to being stainless steel material, so ensure that the sanitation and hygiene by conveying gas or water;2nd, the setting of plastic sheath, can be internal The effect of damping, buffering is played between liner body and exterior tubular body, protection is played a part of with internal liner body;3rd, convergence part one Setting facilitate docking between the mouth of pipe of liner body and external tube mouth, and ensure that the mouth of pipe docking it is smooth Degree, while the abutment joint of both mouths of pipe can also be coated, ensure sealing;4th, the setting of sealing ring one is further protected The sealing between the mouth of pipe of liner body and external tube mouth has been demonstrate,proved, has been effectively prevented the feelings of gas or water leakage Condition.5th, the setting of inner groove one is effectively guaranteed the installation of sealing ring one, and adds sealing ring one on convergence part one Stability.
Preferably, tack coat is provided between the outer wall of the liner body and the inwall of plastic sheath one.
Preferably, the tack coat is glue layer.
Pass through above-mentioned technical proposal, the setting of glue layer so that the company that can stablize between liner body and plastic sheath one Connect, prevent situation about relatively moving between the two.
Preferably, side connector is offered in the side wall of the liner body, the side connector connects provided with stainless steel Take over, plastic sheath two is coated with the stainless steel connecting tube.
Liner body can be achieved in the function being connected on the side with external body in Pass through above-mentioned technical proposal, the setting.
Preferably, the plastic sheath two exceeds the end set of stainless steel connecting tube, and shape backwards to one end of liner body Into convergence part two, inner groove two is offered on the inwall of the convergence part two, sealing ring two is provided with the inner groove.
Preferably, widened diameter of the convergence part one backwards to one end of liner body is set.
Pass through above-mentioned technical proposal, the setting can facilitate extraneous body to enter inside convergence part.
Brief description of the drawings
Fig. 1 is the schematic diagram of medical stainless steel tube inner piece in the present embodiment.
Embodiment
The utility model medical stainless steel pipe inner piece is further described by Fig. 1.
A kind of medical stainless steel pipe inner piece, including liner body 1, it is stainless steel tube, also includes plastic sheath 1, institute State plastic sheath 1 to be coated in the outer circumferential walls of liner body 1, and the both ends of plastic sheath 1 exceed the two of liner body 1 respectively End is set, and forms convergence part 1, i.e., the axial length of plastic sheath 1 is more than the axial length of liner body 1, the linking Inner groove 1 is offered on the inwall in portion 1, sealing ring 1 is equipped with the inner groove 1.
Further, tack coat, the bonding are provided between the outer wall of the liner body 1 and the inwall of plastic sheath 1 Layer is glue layer.
Further, side connector 6 is offered in the side wall of the liner body 1, is welded with not on the side connector 6 The steel connecting tube of becoming rusty 5, plastic sheath 24, and the outer wall and plastic sheath of stainless steel connecting tube 5 are coated with the stainless steel connecting tube 5 Glue layer is again provided between 24 inwall, to increase connection fastness between the two.
Further, the plastic sheath 24 exceeds the end set of stainless steel connecting tube 5 backwards to one end of liner body 1, And convergence part 2 41 is formed, inner groove 2 411 is offered on the inwall of the convergence part 2 41, is set in the inner groove 2 411 There is sealing ring two.
Further, widened diameter 212 of the convergence part 1 backwards to one end of liner body 1 is set.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
