Description

The electric heater of flanged or non-flanged non-metal shell electrothermal tube is housed

Technical field

The utility model relates to electric heater, relates generally to the electric heater that flanged or non-flanged non-metal shell electrothermal tube is housed.

Background technology

Existing for the electrothermal tube in electric heater, 100% is the tubular electrothermal element produced by technical standard JB/T4088-1999 " daily tubular electrothermal element " or JB/T2379-1993 " tubular metal electric heating element ", be " take metal tube as shell, heating alloy make heater; at one end or two ends have eduction rod; in metal tube, load closely knit magnesium oxide powder dielectric, with the element of fixing heater; " be the existing heating generally used; This metal shell heating, is fully immersed in water, and after long-time use, meeting scaling, reduces heating efficiency, and corrosion punctures, and makes water-band electricity, becomes world-famous puzzle.

Recent patent application " non-metal shell heating " application number 201520816869.3 and 201510688413.8 describes through type and blind hole two kinds of non-metal shell heatings; Also have in patent application 201510717411.7 and 201520843141.X " the horizontal single courage storage-type electric water heater having the electrothermal tube of heating wire is housed in non-metallic pipe " practice, find that there is following defect: 1. blind hole pipe has axial force under hydraulic pressure effect, can by electrothermal tube toward extrapolation; 2. main heating part can not sink lower than mounting center line, and the heat production water yield reduces; 3. flange mount pad complex manufacturing technology.

Summary of the invention

The purpose of this utility model will be equipped with in the electric heater of flanged or non-flanged non-metal shell electrothermal tube, propose new technical scheme, to overcome the defect of existing product.

Technical measures of the present utility model are:

The water tank 14 of electric heater is made up of metal or nonmetallic materials, it is built with flanged or non-flanged non-metal shell electrothermal tube, described flanged (FLGD) non-metal shell electrothermal tube blind hole non-metallic pipe is made Curved or straight shape by having the assembly 8 of heating wire and flanged (FLGD) mount pad 11 to be combined into flanged (FLGD) non-metal shell electrothermal tube 5-1 in blind hole non-metallic pipe, in-built electrical heated filament 3, the eduction rod 1 of heating wire one end, U-shaped is bent in pipe, two are made to draw ear of maize in unlimited one end, and by outside nonmetal plug 6 protruded tube, magnesium oxide powder or air 4 is also had in pipe, lead-out wire non-metallic insulation spacer 10 is isolated, prevent short circuit, non-gold pipe is opened wide one end insert in flanged (FLGD) mount pad 11 hole, between the endoporus of mount pad and non-metallic pipe, have seal 2, be used as supporting, sealing and damping, mount pad has screw thread or bayonet socket, match with nut or end cap 13 with it, the function of nut or end cap 13 is blocked by the mouth of pipe of non-metallic pipe 9, if not metal tube is Curved, blind hole one end, under flange mounting center line, can produce more hot water.

Flanged (FLGD) mount pad 11 metal or nonmetallic materials integral manufacturing or split production, be mechanically connected with water tank 14.

Described non-flanged non-metal shell electrothermal tube be by have in blind hole non-metallic pipe the assembly 8 of heating wire with cannot blue mount pad 12 be combined into cannot the non-metal electric heating pipe 5-2 of blue mount pad, it is non-flanged mount pad 12, directly and tank weld or after being mechanically connected, electric heating pipe component 8 is inserted in the hole of mount pad, there is seal 2 between the endoporus of mount pad and non-metallic pipe, be used as supporting, sealing and damping; Mount pad has screw thread or bayonet socket, with nut or end cap 13 combined with it, the function of nut or end cap 13 is blocked by the mouth of pipe of non-metallic pipe 9.

The beneficial effects of the utility model are non-metal shell electrothermal tubes, be connected with water tank with flanged or non-flanged mount pad, Curved or straight shape blind hole pipe is made to overcome axial thrust in water tank, and available flanged or non-flanged electrothermal tube, the existing metal electric heat pipe of direct substitution, make existing product not scaling, leakproof, solve binomial world-famous puzzle.

Accompanying drawing explanation

Fig. 1, Fig. 2 are the electric heaters that flanged (FLGD) non-metal shell electrothermal tube is housed;

Fig. 3 is the electric heater of vertical water tank built with flanged (FLGD) non-metal shell electrothermal tube;

Fig. 4 to Fig. 6 is the outline drawing of several electrothermal tubes adopted in electric heater;

Detailed description of the invention

In accompanying drawing, have in the assembly 7 of heating wire, blind hole non-metallic pipe in eduction rod 1, sealing ring 2, heating wire 3, magnesia powder or air 4, flanged (FLGD) non-metal shell electrothermal tube 5-1, non-flanged non-metal shell electrothermal tube 5-2, nonmetal plug 6, straight-through non-metallic pipe and have the assembly of heating wire (or claiming electric heating pipe component) 8, blind hole non-metallic pipe 9, non-metallic insulation spacer 10, flanged (FLGD) mount pad 11, non-flanged mount pad 12, nut or end cap 13, water tank 14, flange 15;

Fig. 1 is that water tank 14 is built with flanged (FLGD) non-metal shell electrothermal tube, Curved made by blind hole non-metallic pipe 9, can sink down in water tank lower blind bore non-metallic pipe and have heating wire 3, one end of heating wire bends to U-shaped in pipe, make two eduction rods stretch to pipe in unlimited one end, one of them lead-out wire non-metallic insulation spacer 10 entangles; The electrothermal tube that this electrothermal tube and the existing metal tube generally adopted generate heat, mounting means, size for connection is identical, can the existing electrothermal tube of direct substitution, advantage is fairly obvious, because shell is that nonmetallic materials make, would not scaling, can not puncture, realize water proof heating; Fig. 2 be same flanged on have two mount pads, fill two electrothermal tubes.

Because non-metallic pipe is made into Curved, blind hole one end can sink lower than mounting center line, and therefore during preheating, the hot water of generation can be more.

Fig. 3 is when using in vertical water tank, and straight shape made by blind hole non-metallic pipe 8, and this structure is also applicable to vertical or horizontal double water tank structure.

Fig. 3 is flanged (FLGD) mount pad, with metal or nonmetallic materials integral manufacturing, also can split production, and just become the non-metal shell electrothermal tube that can generally use after combining with non-metallic pipe.

Fig. 4 to Fig. 6 is several outline drawings of the electrothermal tube adopted in electric heater, is applicable to single water tank or double water tank; Horizontal or vertical structure.
