Description
Technical field
The present invention relates to a kind of storage-type electric water heater internal container of steel-plastics composite water heater and production method thereof.
Background technology
The storage-type electric water 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, and processing is expensive.Because China's some areas water quality inferiority, stainless steel also can be corroded, and causes seepage.Enamel inner container is frangible, cause corrosion, seepage, influences service life.Its manufacturing equipment requires high, the production cost height.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly can use non-stainless steel manufacturing and resistance to corrosion is strong, the storage-type electric water heater inner bag of anticorrosive coat intensity height, whole low cost of manufacture.For this reason, the present invention by the following technical solutions: it comprises steel shell, internal heater, it is characterized in that being lined with in the described steel shell plastic lining, and steel shell is by cylindrical housings and end cap combination.
Technical problem to be solved by this invention also is to provide a kind of manufacture method of above-mentioned inner bag.It may further comprise the steps;
(1) steel shell branch cylindrical housings and end cap are made respectively,
(2) way with blowing processes plastic lining,
(3) plastic lining is compressed into shell,
(4) adopt one of following manner to seal to the junction of cylindrical housings and end cap:
A. between the plastic lining of described junction and steel shell, load thermal insulation layer, again to end socket and cylindrical housings annular solder,
B. with end socket end flanging, end socket is compressed after assembling lining, ring is pressed the circular cylindrical shell end of body, until securing,
C. on end socket and cylindrical housings, go up screw thread respectively and be connected,
(5) heater is installed.
Advantage of the present invention is that the inner bag shell adopts non-stainless steel manufacturing, with the stainless steel inner container ratio, has reduced manufacturing cost, has improved resistance to corrosion.With the enamel inner container ratio, the high resistance to corrosion of plastic inner lining intensity is strong, and plastic inner lining and housing make the back respectively and install, and production equipment is required low, can reduce equipment investment, and manufacturing cost is lower than enamel inner container.
