Description

Using the electrothermal tube of nonmetallic connectors

Technical field

The present invention relates to electrothermal tubes, relate generally to electric heater, central heater, air source hot pump water heater, solar energy The hot-water heating systems such as water heater, electric boiler, central air-conditioning electricity auxiliary heating, water dispenser, boiler, small kitchen treasured, are immersed in water tank In electrothermal tube.

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.

The content of the invention

The purpose of the present invention is proposing new technical solution to above-mentioned patent application, electricity is fabricated to using nonmetallic connectors Heat pipe.

The technical measures of the present invention are electrothermal tubes by installed part 2, and electrical heating elements 5, connector 6 is formed：The installed part 2 It is to be made of metal material or nonmetallic materials Shooting Technique, electrothermal tube and Water tank for electrical water heater or other water is heated into product The component that is connected of water tank, the tubular member 10 being useful for thereon in insertion connector aperture or be formed with installation connecting element on installed part 6 hole.

The shell of the electric heating element 5 is nonmetallic blind hole pipe or bends to the pipe of U-shaped, interior equipped with heating wire 3, draws 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 electric heating element 5 makes of halide torch or carbon fiber electric heating tube, is single-ended extraction, draws Stick or conducting wire 1 are in the same end；The connector 6 is the component for being connected as one both installed part 2 and electric heating element 5, even Fitting is made of high temperature resistant nonmetallic materials, has hole or its one end to have flanged (FLGD) plane, there is several teeth, each tooth phase in hole When in a sealing ring, itself has leakproofness, and installed part 2 and electric heating element 5 are inserted into both ends of the hole or will be connected respectively Part in the hole of installed 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.

Connector 6 itself the beneficial effects of the invention are as follows electrothermal tube has leakproofness, and transporting for long-distance has shock absorption, and zero Number of packages amount 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 that Figure 16 uses connector；

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

Figure 22 Figure 23 is that nonmetallic or metal blind hole casing structure chart is housed outside electrical heating elements.

Specific embodiment

In attached drawing, eduction rod or conducting wire 1, installed 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 installed part.

Fig. 2, Fig. 3, Fig. 7, Fig. 8 are electrical heating elements and the concentric electrothermal tube installed of installed part, and installed 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 that water is heated Component；Connector 6 is the component for being connected as one both installed 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 connected by connector with installed part 2, 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, installed 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.
