Description

A kind of overlength cast-iron radiator and preparation method thereof

Technical field

The present invention relates to field of heating, specifically a kind of overlength cast-iron radiator and preparation method thereof.

Background technology

Current civil buildings heating radiator field, generally adopts Integral iron casting radiator and steel, aluminum, magnesium to close Deng welding radiator.The cast-iron radiator of casting technique production, long service life, but rough surface, dense internal organization are poor, Because the length of the limited radiator of production technology is restricted, it is impossible to meet current heating demands.The welding such as steel, aluminum, magnesium conjunction Radiator corrosion resisting property is poor, and service life is short, and copper radiator properties are all very good, but due to the too high application of cost very It is few.

The content of the invention

The technical problem to be solved is：How above-mentioned the deficiencies in the prior art are overcome, there is provided an items are new Radiator that can be all good and economical and practical.

The technical solution adopted in the present invention is：Two malleable cast iron head and one or more centrifugal ductile cast iron pipes Connected by interference fit, inside malleable cast iron head, have a hollow pipeline, malleable cast iron head hollow pipeline connection water swivel and One or more centrifugal ductile cast iron pipes joint, a malleable cast iron head water swivel as outlet, another malleable casting Iron plate head water swivel has 20 ° of chamferings, centrifugal ductile cast iron pipes as water inlet, the outlet of centrifugal ductile cast iron pipes joint hollow pipeline There is inside T stage rank two ends periphery, and there are 20 ° of chamferings port, and T stage rank interface has 20 ° of chamferings, has a circle on T stage rank Circle groove, circle groove vertical is in centrifugal ductile cast iron pipes centrage.Centrifugal ductile cast iron pipes can one or more from Bulbus cordis graphite cast iron pipe is used as a use by the length that above-mentioned interference fit connects into needs, and centrifugal ductile cast iron pipes can More than or equal to 1.8 meters, any root centrifugal ductile cast iron pipes can be coupled together by the manner, the individual of heating house is met Property need.

The manufacture method of overlength cast-iron radiator, is carried out according to the steps：

Step one, using the trade mark be KTH 350-10 or KTH 370-12 black heart malleable cast irons make malleable cast iron head, The trade mark is adopted for QT400-15 or QT400-18 ferrite ductile cast irons, centrifugal ductile cast iron is made by way of centrifugal casting Pipe, has a hollow pipeline inside malleable cast iron head, malleable cast iron head hollow pipeline connection water swivel and one or more from Bulbus cordis graphite cast iron pipe joint, the outlet of centrifugal ductile cast iron pipes joint hollow pipeline have 20 ° of chamferings, outside centrifugal ductile cast iron pipes two ends There is inside T stage rank week, port there are 20 ° of chamferings, and T stage rank interface there are 20 ° of chamferings, has a circle groove on T stage rank, Circle groove vertical is in centrifugal ductile cast iron pipes centrage.

Step 2, take two have same centrifugal ductile cast iron pipes joint malleable cast iron head, take a centrifugal ductile Cast iron pipe, loads O shape rubber seal in the centrifugal ductile cast iron pipes circle groove, then by hydraulic means by centrifugal globe The two ends of graphite cast iron pipe are respectively pressed in the centrifugal ductile cast iron pipes joint of two malleable cast iron head, same mode, until The all of centrifugal ductile cast iron pipes joint of malleable cast iron head that two have same centrifugal ductile cast iron pipes joint is all installed Upper centrifugal ductile cast iron pipes, form interference fit between centrifugal ductile cast iron pipes joint and centrifugal ductile cast iron pipes.

As a kind of optimal way, it is characterised in that the material that O shapes rubber seal is adopted in second step is ethylene methacrylic Base silicone rubber.

The invention has the beneficial effects as follows：Overlength cast-iron radiator of the present invention is solved in existing cast-iron radiator production process Solid and gas pollutant discharge many, length and are restricted；Steel, Al alloys andMg alloys matter radiator high energy consumption, service life are short；Copper The too high problem of matter radiator cost.The product for being produced has any surface finish, high corrosion-resistant, pressure-bearing, low cost, life-span length etc. Feature.

Specific embodiment

As shown in Fig. 1 to Fig. 4, a kind of overlength cast-iron radiator of the invention, malleable cast iron head and centrifugal ductile cast iron pipes Connected by interference fit, inside malleable cast iron head, have a hollow pipeline, malleable cast iron head hollow pipeline connection water swivel and One or more centrifugal ductile cast iron pipes joint, the outlet of centrifugal ductile cast iron pipes joint hollow pipeline have 20 ° of chamferings, centrifugal globe There is inside T stage rank graphite cast iron pipe two ends periphery, and there are 20 ° of chamferings port, and T stage rank interface has 20 ° of chamferings, on T stage rank There is a circle groove, circle groove vertical is in centrifugal ductile cast iron pipes centrage.

According to radiator overall dimensions and technological requirement and according to interference connection and the physical dimension and work of seal request Skill requires malleable cast iron head and centrifugal ductile cast iron pipes needed for manufacture.The use of the trade mark is KTH 350-10 or KTH 370-12 Black heart malleable cast iron makes malleable cast iron head, adopts the trade mark for QT400-15 or QT400-18 ferrite ductile cast irons, passes through The mode of centrifugal casting makes centrifugal ductile cast iron pipes, has hollow pipeline inside malleable cast iron head, and malleable cast iron head are hollow Pipeline connects water swivel（For water receiving pipe）With one or more centrifugal ductile cast iron pipes joint, centrifugal ductile cast iron pipes joint Hollow pipeline outlet has 20 ° of chamferings, and there is inside T stage rank centrifugal ductile cast iron pipes two ends periphery, and there are 20 ° of chamferings port, T-shaped Step interface has 20 ° of chamferings, has a circle groove on T stage rank, and circle groove vertical is in centrifugal ductile cast iron pipes centrage. Centrifugal ductile cast iron pipes can connect into needs by above-mentioned interference fit one or more centrifugal ductile cast iron pipes Length as one use, centrifugal ductile cast iron pipes can be more than or equal to 1.8 meters.

Two pieces malleable cast iron head are distinguished fixing end and movable end of the clamping in frame, it is middle to place two ends circle ditch Centrifugal ductile cast iron pipes of the groove equipped with O shape rubber seal.Two internal thread hole of malleable cast iron head（Connection water swivel）Be inserted in On the vertical round steel of the little Jing identicals of female thread；Below centrifugal ductile cast iron pipes two ends, frame is on v block.Starting hydraulic means will be living The malleable cast iron head of moved end push centrifugal ductile cast iron pipes one end mouth of pipe to, then by the centrifugal ductile cast iron pipes other end mouth of pipe The malleable cast iron head of fixing end are moved closer to, until the two ends of centrifugal ductile cast iron pipes are respectively pressed into two malleable cast iron pieces Head forms interference fit between centrifugal ductile cast iron pipes joint and centrifugal ductile cast iron pipes to being sized completing connection.

Remove from frame, through pressure testing, drying, polishing flow process, make overlength single-column or multicolumn cast-iron radiator finished product. Although there are one and two centrifugal ductile cast iron pipes joints in only depicting malleable cast iron head in figure in addition, It is it should be understood that can have a case that three or more than three centrifugal ductile cast iron pipes joints in malleable cast iron head.
