Description
Technical field:
Multilayered structure and multifunction pipeline and connection set, the corruption shortcoming that it has reduced pipeline and joint has increased working life of pipeline and joint.Increase the crushing resistance of pipeline and joint.Also has the effect of sterilization.Making, the installation cost of pipeline have been reduced.Increased the aesthetic property of pipeline.The pipeline of insulation usefulness can also increase the heat insulating ability of pipeline.It is used for fields such as water works, transport pipe, waste pipe, the conveying of corruption liquid.
Technical background:
Pipeline in the market and piecing devices mostly are simple galvanized iron conduit and simple plastic article, because pipeline is embedded in underground for a long time and is exposed in the air, simple metallic iron goods are easy to oxidation and rusting.Reduced the working life of pipeline greatly, and also will waste very big manpower after damaging and keep in repair.
Simple plastic article, though can not get rusty as the PVC water pipe, its crushing resistance and anti-collision performance are very poor.When being under pressure and clash into, be easy to damage, also make very big the reducing of its scope in application facet.If increase crushing resistance and anti-corruption property by the thickness that increases pipeline.Increase fabricating cost that can be very big.
PP-R is the atactic copolymerized polypropene plastic pipe, and it has good performance, but it also has deficiency, as the irradiation of UV resistant, install connect trouble, heat-resisting low, crushing resistance neither finely particularly be easy to become fragile under low temperature 5 platings Celsius.Heat insulating ability neither be fine.
Simple with the metal that is difficult for getting rusty as: nickel and nickel alloy, aluminium and aluminum alloy, copper etc. are made pipeline, and fabricating cost can increase greatly.
Spray one deck anticorrosive coat if adopt in the inside or the outside of metallic conduit.Coating is easy to wearing and tearing and decortication, and pipeline also can be easy to get rusty.
One deck stainless steel, metallic copper, pottery are placed in the invention that has in metallic conduit, or one deck plastics, and skin still is the simple galvanized iron conduit that gets rusty easily.The nexine of pipeline is can not get rusty like this, but pipeline all is to be embedded in underground or to be exposed in the air, the outside of pipeline also can with moisture content and the rapid oxidation and rusting of air in the earth.And the pipeline that gets rusty that is positioned at ground surface is very not attractive in appearance yet.
The invention that has is to add one deck stainless steel or metallic copper in the plastic pipe the inside, if reach measuring body effect with the thickness that increases plastics, stainless steel lining in that pipeline and metal copper layer are just nonsensical, because plastics can not get rusty.Reach measuring body purpose if increase the stainless steel lining or the metal copper layer of internal layer, those outer field plastics also are unnecessary, and fabricating cost also can very big increase in addition.
Also having the joint of pipeline all is with simple metal threaded and plastic construction, and its device is simple.The joint that worm structure arranged will just butt up against the worm structure of joint with the screw thread that thing is wrapped in pipeline in order to prevent to leak when installing, waste time and energy so very much.
Principle of the present invention is to adopt the multi-layer structure more than three layers or three layers to form, and can make according to the needs of as installed, can learn from other's strong points to offset one's weaknesses, the advantage that reach pipeline and have that anti-corrosive properties are good, crushing resistance is good, good heat preservation performance, sterilization, fabricating cost is low etc.
