Description

Using the electrothermal tube of nonmetallic connectors

Technical field

The utility model is related to electrothermal tube, electric heater, central heater, air source hot pump water heater, too are related generally to The hot-water heating systems such as positive energy water heater, electric boiler, central air-conditioning electricity auxiliary heating, water dispenser, boiler, small kitchen treasured, are immersed in Electrothermal tube in water tank.

Background technology

Patent application 201520996947.2 and 201510860091.0《Flanged or non-flanged non-metal shell electric heating Pipe》With patent application 201610087130.2 and 201620118841.7《A kind of combined electrical heat pipe》Propose the knot of electrothermal tube Configuration formula, present patent application are a kind of new structure type of supplement.

Utility model content

The purpose of this utility model is that new technical solution is proposed to above-mentioned patent application, is made of nonmetallic connectors At electrothermal tube.

The technical measures of the utility model are electrothermal tubes by installation part 2, electrical heating elements 5, the composition of connector 6：The peace Piece installing 2 is made of metal material or nonmetallic materials Shooting Technique, and electrothermal tube and Water tank for electrical water heater or other water are added The component that the water tank of hot product is connected is useful for being inserted into thereon in tubular member 10 or installation part in connector aperture and is formed with installation The hole of connector 6.

The shell of the electric heating element 5 is nonmetallic blind hole pipe or bends to the pipe of U-shaped, interior that heating wire 3 is housed, and is drawn Stick or conductor wire end will seal, and manage interior pumping low vacuum or inject non-combustible, not combustion-supporting gas or inert gas or be packed into non-close Real magnesium oxide powder and air；Or the halide torch of electric heating element 5 or carbon fiber electric heating tube make, and are single-ended extraction, draw Stick or conducting wire 1 are in the same end；The connector 6 is the component for being connected as one both installation part 2 and electric heating element 5, even Fitting is made of high temperature resistant nonmetallic materials, has hole or one end to have flanged (FLGD) plane, there is several teeth, each tooth phase in hole When in a sealing ring, itself has leakproofness, installation part 2 and electric heating element 5 are inserted into both ends of the hole respectively, or will connection Part in the hole of installation part, outside clamped with clip 7 or compress connector；Permission is anodontia in connector aperture, but internal diameter The caliber of connection must be less than.

The utility model has the beneficial effects that there is the connector 6 of electrothermal tube itself leakproofness, long-distance transport to have shock-absorbing Property, number of parts is few, and heating wire surface loading is low, and service life is long, is most preferred structure.

Figure 12 to Figure 15 is connector outline drawing；

Figure 16 is another form using nonmetallic connectors electrothermal tube；

Figure 17 is the outline drawing of the used connectors of Figure 16；

Figure 18 should be sealed to Figure 21 eduction rods or conductor wire end；

Figure 22, Figure 23 are another structure charts of electrothermal tube.

Specific implementation mode

In attached drawing, eduction rod or conducting wire 1, installation part 2, heating wire 3, inert gas or non-combustible, not combustion-supporting gas or low Spend vacuum gas or magnesium oxide powder or air 4, electrical heating elements 5, connector 6, clip 7, nonmetallic isolated tube 8, insulator 9, Tubular member 10, fluid sealant 11.

Fig. 1 is the out of line electrothermal tube of both electrical heating elements and installation part.

Fig. 2, Fig. 3, Fig. 7, Fig. 8 are electrical heating elements and the concentric electrothermal tube installed of installation part, and installation part 2 is by electrothermal tube On the water tank of electric heater or other hot water apparatus, and the component being fixed up, electrical heating elements 5 are heated to water Component；Connector 6 is the component for being connected as one both installation part and electrical heating elements；Fig. 5 extremely schemes to Fig. 8, Figure 16, Figure 19 21 electrical heating elements 5 are made for U-shaped, built-in heating wire 3 or injection inert gas or non-combustible, not combustion-supporting gas or low vacuum Gas or magnesium oxide powder or air or electrical heating elements 5 make of carbon fiber pipe or halide torch；The structure pole of this electrothermal tube To be simple, and it is reliable, existing metal electric heating pipe can be substituted completely.

Figure 18 is blind hole pipe, and Figure 19 Figure 20 is U-tube, and Figure 21 is that U-tube is directly connect with installation part 2 by connector, It in attached drawing, nonmetallic blind hole pipe or bends in the pipe of U-shaped, after injecting protective gas, heating wire sectional area can reduce, surface Load can improve, and service life can be longer；In attached drawing, some figures are similar, and production method is different, but claim phase Together.

In attached drawing, installation part 2 is dish type, can be made according to actual needs it is tubular, its it is outer or its in, connected using screw thread It connects；Tubular member 10 also has different structure；Fig. 1 to Figure 21 is suitable for horizontal installation, vertical can also install.
