Abstract
The utility model relates to a steel-plastic composite liner for a water heater, which comprises a steel outer shell and a built-in heater. A plastic lining is arranged in the steel outer shell.
Description
The utility model relates to a kind of water-storage electric heater and moulds composite inner liner with steel.
The water-storage electric heater liner material has two kinds at present, and a kind of is the stainless steel manufacturing, and another kind is the steel enamel material.Make the inner bag complex process with stainless steel, the power consumption of polymer processing height need expend a large amount of non-ferrous metals, costs an arm and a leg.Because China's some areas water quality inferiority, stainless steel also can be corroded, and causes seepage.Enamel inner container is frangible, causes corrosion, seepage, influences service life.Its manufacturing equipment requires high, the production cost height.
The purpose of this utility model provides a kind ofly can use non-stainless steel manufacturing and resistance to corrosion is strong, the water-storage electric heater inner bag of anticorrosive coat intensity height, whole low cost of manufacture.
The utility model comprises steel shell, internal heater, is lined with a plastic lining in the described steel shell.
Described steel shell is by cylindrical housings and end cap combination.
The utility model has the advantages that the inner bag shell adopts non-stainless steel manufacturing,, reduced manufacturing cost, improved resistance to corrosion with the stainless steel inner container ratio.With the enamel inner container ratio, plastic inner lining intensity, high resistance to corrosion are strong, and plastic inner lining and housing attach together after making respectively, production equipment are required low, can reduce equipment investment, and manufacturing cost is lower than enamel inner container.
Further specify the utility model below in conjunction with accompanying drawing

Embodiment one
With reference to Fig. 1, Fig. 3: welding constitutes the steel casing of the utility model water heater liner at the A place by cylindrical housings 1 and end cap 2, is lined with plastic lining 3 in the steel casing.Have intake-outlet 5 on the cylindrical housings 1.Ring-type weld seam 7 places in the junction of cylindrical housings 1 and end cap 2 are equipped with thermal insulation layer 6 between steel casing and the plastic lining, thermal insulation layer 6 is filled insulations, as clay, cement, gypsum etc.The effect of thermal insulation layer 6 is to prevent to destroy when welding cylindrical shape housing 1 and end cap 2 plastic lining 3.
Tension type mounting means in heater 4 adopts: heater 4 is fixed on the built-in heating flange 10, heating flange 10 connecting bolts 11, and bolt 11 and nut are installed on the support arm, and heating flange 10 is equipped with the leakproof rubber cushion with the contact site of shell.
Production method of the present utility model comprises following production stage:
(1) steel shell is divided cylindrical housings 2 and end cap 1 make respectively.
(2) way with blowing processes plastic lining 3
(3) plastic lining 3 is compressed into shell
(4) to loading thermal insulation layer 6 between the plastic lining 3 of the junction of cylindrical housings 2 and end cap 1 and the steel shell, again to end socket and cylindrical housings annular solder,
(5) heater is installed
Embodiment two
With reference to Fig. 1, Fig. 2, Fig. 4: the steel casing of the utility model water heater liner is connected and composed at the A place by cylindrical housings 1 and end cap 2, is lined with plastic lining 3 in the steel casing.Have intake-outlet 5 on the cylindrical housings 1.8 places, ring splenium position in the junction of cylindrical housings 1 and end cap 2, the end of the flange of end socket 2 and cylindrical housings 1 firmly connect through annular panel beating pressing.
Embodiment three
With reference to Fig. 1, Fig. 5: the steel casing of the utility model water heater liner is connected and composed through screw thread 9 at the A place by cylindrical housings 1 and end cap 2, is lined with plastic lining 3 in the steel casing.Have intake-outlet 5 on the cylindrical housings 1.
Tension type mounting means in heater 4 adopts: heater 4 is fixed on the built-in heating flange 10, heating flange 10 connecting bolts 11, and bolt 11 and nut are installed on the support arm, and heating flange 10 is equipped with the leakproof rubber cushion with the contact site of shell.
