Detailed description of the invention
As shown in Fig. 1 to Fig. 4, a kind of overlength cast-iron radiator of the present invention, malleable cast iron head are connected by interference fit with centrifugal ductile cast iron pipes, there is hollow pipeline malleable cast iron head inside, malleable cast iron head hollow pipeline connects water swivel and one or more centrifugal ductile cast iron pipes joint, the outlet of centrifugal ductile cast iron pipes joint hollow pipeline has 20 ° of chamferings, there are inside T stage rank periphery, centrifugal ductile cast iron pipes two ends, port has 20 ° of chamferings, T stage rank interface has 20 ° of chamferings, T stage rank there is a circle groove, circle groove vertical is in centrifugal ductile cast iron pipes center line.
Malleable cast iron head needed for manufacturing according to the appearance and size of radiator and technological requirement and according to the physical dimension of interference connection and seal request and technological requirement and centrifugal ductile cast iron pipes.Use the trade mark for KTH 350-10 or KTH 370-12 black heart malleable cast iron making malleable cast iron head, the trade mark is adopted to be QT400-15 or QT400-18 ferrite ductile cast iron, centrifugal ductile cast iron pipes is made by the mode of centrifugal casting, there is hollow pipeline malleable cast iron head inside, malleable cast iron head hollow pipeline connects water swivel (for water receiving pipe) and one or more centrifugal ductile cast iron pipes joint, the outlet of centrifugal ductile cast iron pipes joint hollow pipeline has 20 ° of chamferings, there are inside T stage rank periphery, centrifugal ductile cast iron pipes two ends, port has 20 ° of chamferings, T stage rank interface has 20 ° of chamferings, T stage rank there is a circle groove, circle groove vertical is in centrifugal ductile cast iron pipes center line.Centrifugal ductile cast iron pipes can connect into the length of needs as a use using one or more centrifugal ductile cast iron pipes by above-mentioned interference fit, and centrifugal ductile cast iron pipes can be more than or equal to 1.8 meters.
