Description
Technical Field
The utility model relates to a drinking water tubular product technical field, concretely relates to novel antibiotic lining is moulded and is forged cast iron pipe fitting.
Background
In the prior art, a PE or PVC plastic pipe is generally adopted as a main building material of a drinking water delivery system. However, tap water is not absolutely pure and sterile, and people can see that a layer of dirt is hung in the pipe or the inner wall of the pipe fitting after the pipe system is disassembled after water is delivered for a period of time. The dirt is attached to the slight and uneven position of the pipe wall by impurities in water, bacteria are continuously bred in the impurities, and finally a sticky dirt layer is formed, so that the conventional PE or PVC plastic pipe does not have a sterilization effect. In addition, the PE or PVC plastic pipe has poor mechanical strength, particularly poor external pressure resistance, impact resistance and thermal deformation resistance, and is easy to break when being subjected to external extrusion, impact or high temperature. Therefore, it is necessary to provide a drinking water pipe with good mechanical properties and sterilization effect.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a novel malleable cast iron pipe fitting is moulded to antibiotic lining has excellent mechanical properties and efficient antibacterial property simultaneously.
In order to realize the technical scheme, the utility model provides a novel but antibiotic lining plastic forging cast iron pipe fitting, include: the hot galvanizing forged cast iron pipe is characterized in that an antibacterial plastic pipe is integrally formed on the inner side of the hot galvanizing forged cast iron pipe in an injection molding mode.
In the technical scheme, the antibacterial plastic pipe is formed by uniformly mixing 94-97% of polyethylene, 1-2.0% of color master and 2-4% of antibacterial agent in percentage by mass, and then heating and extruding the mixture, and has a good antibacterial function. By sleeving the hot-dip galvanized forged cast iron pipe on the outer layer of the antibacterial plastic pipe, the external compression resistance, impact resistance and heat deformation resistance of the antibacterial plastic pipe can be effectively enhanced, and the antibacterial plastic pipe is well protected. The antibacterial plastic pipe is integrally injected on the inner side of the hot galvanizing forged cast iron pipe through an injection mold, and then is cooled and formed, so that the interlayer bonding strength between the hot galvanizing forged cast iron pipe and the antibacterial plastic pipe can be enhanced.
Preferably, a threaded interface is arranged at the end opening of the hot-galvanized forged cast iron pipe, so that the antibacterial plastic-lined malleable cast iron pipe fitting can be quickly connected.
Preferably, the outer surface of the hot-dip galvanized forged cast iron pipe is sequentially coated with a wear-resistant coating layer, an acid and alkali corrosion resistant coating layer and a heat insulation coating layer from outside to inside, wherein the wear-resistant coating layer has the function of improving the wear resistance of the surface of the hot-dip galvanized forged cast iron pipe, particularly improving the protection of the antibacterial plastic-lined composite metal pipe on the hot-dip galvanized forged cast iron pipe in the construction and installation process, and the acid and alkali corrosion resistant coating layer can improve the acid and alkali corrosion resistance of the hot-dip galvanized forged cast iron pipe so as to meet the installation requirements of some special use occasions; the heat-proof coating layer can improve the heat-proof quality of hot-galvanize forged cast iron pipe, because antibiotic plastic tubing warp easily under the high temperature, the heat conductivility of hot-galvanize forged cast iron pipe is good, consequently uses under the high temperature condition, leads to antibiotic plastic tubing because outside high temperature transmission leads to warping easily, influences the use, through set up the heat-proof coating layer in hot-galvanize forged cast iron pipe surface can be fine solve above-mentioned problem.
The utility model provides a pair of novel antibiotic lining is moulded malleable cast iron pipe fitting's beneficial effect lies in: this novel but forging cast iron pipe fitting is moulded to antibiotic lining has good antibiotic function to through at the outer hot-galvanize forging and casting iron pipe of cup jointing of antibiotic plastic tubing, can effectively strengthen the outside resistance to compression, anti striking, the thermal deformation resistance performance of antibiotic plastic tubing, realize the good protection of antibiotic plastic tubing, antibiotic plastic tubing passes through the integrative inboard of moulding plastics at hot-galvanize forging and casting iron pipe of injection mold, then cooling forming, can strengthen the interlaminar bonding strength between hot-galvanize forging and casting iron pipe and the antibiotic plastic tubing.
