Portion is provided with internal thread groove, and the internal thread groove is internally provided with double-layer seal rings, and the birdsmouth outer surface is provided with outer
Thread groove.
Further, the external tube layer outer wall surface is provided with heat-barrier coating, and the external tube layer outer surface is provided with
Reinforcing rib, said inner tube layer are internally provided with damping spring, and said inner tube layer inner wall surface is provided with beryllium copper layer and stenlizing layer, institute
It states beryllium copper layer and is located at stenlizing layer side.
Further, the external tube layer diameter is more than interior tube layer diameter.
Further, the socket end is threadedly coupled with birdsmouth.
Compared with prior art, the utility model has the advantages that：
1, this kind of a kind of PVDF tubing with heat insulation effect, by the efficient thermal insulation material and heat-barrier coating of setting,
Using in cavity inside, efficient thermal insulation material is set, it can be to playing insulation effect inside PVDF tubing, while being arranged heat-insulated
Protective layer can make outwardly and inwardly air partition, reduce heat loss through conduction, reinforce heat preservation intensity.
2, by the reinforcing rib of setting and beryllium copper layer, it can be effectively increased PVDF tubing intensity, make tubing can be at by bigger
Pressure, anti-impact force is stronger, can enhance the hardness of pipeline, prevent pipeline due to by sharppointed article destruction cause flow to leak
The case where, while interior tube layer being provided with damping spring, have the function of certain damping, buffering pressure, to avoid pipeline from damaging
It is bad, prolong the service life, the setting of stenlizing layer can effectively enhance the safety non-pollution of water quality inside PVDF tubing.
3, by the socket end of setting, birdsmouth, internal thread groove and external thread groove, traditional PVDF tubing is generally using slotting
The mode connect is attached, but general inserting mode is not secured enough, the case where falling off easily is generated, in being arranged in socket end
Thread groove and it can effectively be fastenedly connected intensity in birdsmouth setting external thread groove, while can be with by the double-layer seal rings of setting
Reinforce sealing intensity, flow is avoided to leak outside.
