Abstract
The invention relates to a 300-4,000mm water feed winding double tube, which can meet water feed hygienic standard and has high compression strength, and a manufacturing method thereof. The water feed winding double tube comprises a water feed tube, wherein the water feed tube consists of an inner layer, a core layer and an outer layer through compounding; the inner layer and the outer layer are polyurethane (PE) plastic layers; and the core layer is a glass fiber plastic mixed layer. The invention has the advantages that: 1, the tube is 40 percent lighter than a similar solid-wall PE tube and saves PE materials by 40 percent under the condition of same tube diameter; 2, the tube has high pressure resistance which is more than three times that of the same solid-wall tube; and 3, the tube is convenient to connect, a tube can be connected within 15 minutes reliably, and the tube has no leakage absolutely.
Description
Technical field
The present invention relates to a kind of water supply hygiene standard that both satisfied, have again the high a kind of 300-4000mm feedwater of compressive strength and be wound around two spirit pipes and making method, belong to supply pipe and make the field.
Background technique
CN1266155Y, title " a kind of plastic water supply pipe ", its body has inner tube layer and external tube layer, within the inner tube layer is placed on external tube layer, it is characterized in that described external tube layer made by igelite, and the inner tube layer is made by the TPO plastics.The PVC＝polyvinyl chloride external tube layer of supply pipe of the present invention can guarantee that tubing has higher intensity, rigidity and weatherability, and its inner tube layer can guarantee that water quality is not contaminated.The manufacture cost of supply pipe of the present invention is lower and be suitable for making the heavy caliber pipe of 63～315mm than aluminium-plastic composite pipe.The bonding way that can adopt supply pipe of the present invention easily realizes connecting, thus the seepage that can effectively avoid the joint to occur.Its deficiency: compressive strength is low, and in equal withstand voltage situation, its manufacture cost is very high.
Summary of the invention
Purpose of design: avoid the deficiency in background technique, design a kind of water supply hygiene standard that both satisfied, have again the high a kind of 300-4000mm feedwater of compressive strength and be wound around two spirit pipes and making method.
Design proposal: in order to realize above-mentioned purpose of design.Supply pipe is equipped with by internal layer and outer interlayer the design that glass fibre is moulded mixing layer, is technical characteristics of the present invention.The purpose of doing like this is: because glass fibre has good insulating, heat resistance is strong, corrosion resistance good, the characteristics that mechanical strength is high, it mixes the sandwich layer of institute's moulding with the PE plastics, after tested: not only mechanical strength is high, and withstand voltage properties is very high, is more than 10 times of PE withstand voltage properties, therefore with it as the supply pipe sandwich layer, internally can effectively bear the hydraulic pressure from internal layer (in pipe), externally can bear extraneous pressure, guarantee that supply pipe is indeformable, do not damage.
Technological scheme 1: a kind of 300-4000mm feedwater is wound around two spirit pipes, and it comprises supply pipe, and described supply pipe is by internal layer, sandwich layer and outerly compoundly consist of, and internal layer and skin are pure PE plastic layer, and sandwich layer is that glass fibre is moulded mixing layer.
Technological scheme 2: a kind of 300-4000mm feedwater is wound around the making method of two clever pipes, the PE plastic strip of first plastic extruder being extruded is fine and close in being wrapped on core with revealing and consisting of the supply pipe internal layer, then the glass fibre mixture is extruded the strip mixture by plastic extruder fine and close in being wrapped in supply pipe PE internal layer with revealing and consisting of the supply pipe sandwich layer, the PE plastic strip of again plastic extruder being extruded is fine and close in being wrapped on core with revealing and consisting of the supply pipe skin, is embedded with electrical heating wire in last supply pipe joint socket wall.
The present invention compares with background technique, and the one, more lightweight 40% than similar real wall PE pipe under the condition of same caliber, save PE material 40%; The 2nd, withstand voltage height is higher more than 3 times than similar solid wall pipe; The 3rd, the connecting part makes, can connect about 15 minutes one and connect reliable, 100% ne-leakage.
