Abstract
The invention relates to an improved water heater electric heating pipe comprising a pipe body. The outer side of the pipe body is successively coated with a high-temperature-resistant layer, an anticorrosion layer, and an anti-oxidation layer. A leading-out rod and a resistance wire are arranged in the pipe body. One end of the leading-out rod is connected with the resistance wire. The other end of the leading-out rod extends out of the pipe body. Both ends of the pipe body are equipped with high-temperature glass-dead seal layers and temperature control protection devices. A silica gel sleeve is arranged on the junction of the leading-out rod and the outer side of a pipe opening. A magnesium oxide filling layer is uniformly filled between the resistance wire and the inner side of the pipe body. By means of the above improvement, the improved water heater electric heating pipe has characteristics of corrosion resistance, oxidation resistance, good thermal conductivity, good security without electric leakage, and good applicability.

Technical field
The present invention relates to water heater heating clothing arts, be specifically related to a kind of electric heater electric heating tube of improvement.
Background technology
Tubular electrothermal element (electrothermal tube) take metal tube as shell (comprising stainless steel, copper tube), along central shaft in pipe, there is to distributing auger lectrothermal alloy wire (nickel chromium triangle, ferrochrome) its fill gaps compacting the magnesium oxide sand of good insulation heat conductivility, mouth of pipe two ends silica gel sealing, this metal armouring electric heating element can add hot-air, metal die and various liquid.In prior art, electric heating tube as water heater heating equipment use time, there will be the corrosion of electrothermal tube tubing when water quality is not good and there is the situation of oxidizable unstable properties when resistance wire runs into high temperature, and there is moisture-sensitive as the magnesia powder of insulating heat-conduction material thus cause the generation of electrical leakage problems.
Summary of the invention
The present invention is directed to prior art Problems existing, provide a kind of applicability strong, the Water heater electric heating tube of the improvement of good, the high temperature resistant and use safety of corrosion resistance.
A kind of technical scheme provided by the invention is: a kind of Water heater electric heating tube of improvement, comprise body, described body outside scribbles high-temperature-resistant layer from inside to outside successively, corrosion-resistant coating and anti oxidation layer, eduction rod and resistance wire is provided with in described body, described eduction rod one end is connected with resistance wire, the eduction rod other end extends to body outside, body two ends are equipped with high temp glass sealing layer, described body two ends are also respectively equipped with temperature control protective device, junction outside described eduction rod and the mouth of pipe is provided with silica gel sheath, uniform filling magnesium oxide packed layer in described body and between resistance wire.
Further improvement of the present invention is: described body is Ying Gelai 800 stainless steel seamless pipe.
Further improvement of the present invention is: described resistance wire is the resistance wire of spiral helicine high-resistance electrothermic alloy.
Further improvement of the present invention is: the magnesia powder that described magnesium oxide packed layer is filled is modified oxidized magnesium packed layer.
Beneficial effect of the present invention is: 1, applicable different water quality, and applicability is strong, good stability.2, anticorrosive non-oxidizability is strong.3, heat conductivility is good.4, leakproof, fail safe is good.5, long service life.
