Description
The utility model relates to a kind of compensation pipeline heat dissipation, and making equipment, the especially insulating material of the material maintenance constant temperature in the pipeline is the parallel heating arrangement made from silicon rubber.
Though existing silicon rubber ribbon heater has good insulation performance and pliability, owing to adopt cascaded structure, press the certain-length manufacturing, it can not be sheared arbitrarily by actual Len req, otherwise can influence whole heating.Document (1) is described to be present typical a kind of silicon rubber ribbon heater, has above defective.
Though its length of existing ribbon heater can be made arbitrarily, can shear arbitrarily by actual Len req, make insulating material owing to adopt fluoroplastics, smooth surface, frictional resistance and little, the spiral heating line of Juan Raoing can't be located in the above, make and use in can occur moving, lax, crooked, turn-to-turn collides (because of pitch is generally 0.5～1.5mm) formation turn-to-turn short circuit, surpassed heating joint rated power, caused heating wire to blow, made parallel connection be with some heating joint not generate heat.Accompany when hot when it is used for industrial pipeline, some position temperature of pipeline is descended, medium solidifies, and line clogging causes operation to stop production.In addition, this ribbon heater is crooked flexible relatively poor, and the ratio of minimum bending radius and its thickness is greater than 5, and is too much because of bending when the substandard occasions of some shapes such as being used for valve, flange, conduit fittings is accompanied when hot, and difficulty is installed, and damages easily.Document (2) is described to be typical parallel-connection structure, has above-mentioned defective.
The purpose of this utility model provides a kind of silicon rubber parallel type electric heating strip.It not only can be sheared by the random length manufacturing, by any Len req and use, and the heating line is reliably located, avoid generating heat line make and use in move, lax, bending, turn-to-turn collide, and has fabulous crooked flexible.
The purpose of this utility model is achieved in that a banded electric heating element of being made up of transmission pressure, silicon rubber insulation skeleton, PTC alloy heat generating line, solder joint, silicone rubber insulation layer, wire sheathing and anticorrosive coat.It is characterized in that: in the silicon rubber insulation skeleton of band shape, place two or three transmission pressures that are parallel to each other along its length, spirality on the silicon rubber insulation skeleton around on PTC alloy heat generating line, on PTC alloy heat generating line, coat silicone rubber insulation layer, wire sheathing and anticorrosive coat respectively successively.PTC alloy heat generating line spiral wound is positioned on the partial cut-out by equal helix pitch between silicon rubber insulation insulation framework and silicone rubber insulation layer and along its length successively, alternate cycles ground is equidistant to weld conducting with each transmission pressure, form along its length a heating joint loop successively, because this structure is to make basic heat-generating units by the heating joint, so factory length can be any, when using, shear by actual Len req, only cut off a heating joint shearing the position and can not influence energising all the other heating joints partly, therefore can not influence whole the heating.Because silicon rubber is a kind of elastomer, so work as PTC alloy heat generating line spiral wound on the silicon rubber insulation skeleton, produce depression in its surface, although the helix pitch of PTC alloy heat generating line on the silicon rubber insulation skeleton has only 0.5～1.5mm, because PTC alloy heat generating line has dented into silicon rubber insulation skeleton surface, produce firm axial location, can not produce mobile, lax, crooked, turn-to-turn and collide and cause short circuit, thereby avoid the heating joint to burn out.Because the percentage elongation of silicon rubber can reach more than 350%, improve greatly than fluoroplastics, and the ratio of its minimum bending radius and its thickness is not more than 2.5, so the silicon rubber parallel type electric heating strip has good bending flexible.And the unit price of silastic material is 20～30 yuan/kg on the present market, and proportion is about 1.2g/cm
3The unit price of fluoroplastics is 150～200 yuan/kg, and proportion is 2.2g/cm
3So the silicon rubber parallel type electric heating strip has very high economy by contrast, can be a large amount of construction investments of pipeline tracing saving.
