Abstract

The utility model relates to a heat insulation vacuum tube. The utility model has the structure that a plastic inner tube is arranged in a plastic outer tube; one end of the plastic outer tube and one end of the plastic inner tube are aligned, and an end surface between the plastic outer tube and the plastic inner tube is provided with an annular sealing plate; inner screw threads for connection are arranged in the plastic inner tube, and the plastic outer tube and the other end of the plastic inner tube are extended with joints with outer screw threads for a plastic inner tube; an annular sealing plate is arranged between the end surface of the plastic outer tube and the plastic inner tube; an evacuated vacuum chamber is arranged between the plastic inner tube and the plastic outer tube. The utility model which can effectively prevent heat dissipation has the advantages of good heat insulation effect, long service life, light weight, convenient installation and transportation, labor saving, and low cost.

Description

Heat proof vacuum tube

The utility model relates to a kind of heat proof vacuum tube that is used on the heating pipeline.

Present heating pipeline is substantially all made of metallic material, and metallic material conducts heat fast, and thermal insulation property is poor, and the part heat so heating pipeline can scatter and disappear even skin adds thermal insulating material, also has the part heat and is lost on the pipeline; The corrosion resistance of metal is poor, so working life is short; The rough surface of metal tubes is deposited dirt easily, and not easy cleaning, and metal material is heavier, installs, transports all inconveniences, wastes time and energy the cost height.

The purpose of this utility model is to provide a kind of good heat insulating, long service life, the heat proof vacuum tube that cost is low.

The purpose of this utility model is achieved in that

One plastic inner pipe is installed in plastic outer tube, said outer tube aligns with interior Guan Yiduan and the end face between two pipes is installed a ring sealing plate, there is the internal thread that connects usefulness the pipe the inside in said, the other end of said outer tube and interior pipe stretches out pipe outside thread coupling head in, one ring sealing plate is installed between the end face of said outer tube and interior pipe, is evacuated vacuum chamber between pipe and the outer tube in said.During installation, as long as the internal and external threads between the tube and tube connects, owing to be vacuum between the inner and outer pipes, so good heat insulating, body can be made straight tube, bend pipe or pipe joint etc., and adaptive capacity is strong.

In the said vacuum chamber dunnage is installed in the above.

The pipe collar of reinforing function can have been installed in the connection place of said pipeline in the above.

Above said internal thread and outside thread be respectively closely-pitched internal thread and closely-pitched outside thread.

Advantage of the present utility model is:

Because between the interior pipe of pipeline and the outer tube is vacuum chamber, can effectively prevent heat dissipation, good heat insulating; Because interior pipe and outer tube all adopt plastic materials to make, the thermal conductivity of plastics is poor with respect to metallic material, and heat radiation is slow, has increased heat insulating ability; The anti-corrosion capacity of plastics is strong, and is not fragile, long service life; The smooth surface of plastic piping is difficult for depositing dirt, cleans easily; Plastics is in light weight simultaneously, and installation and transportation are convenient and strength-saving, and cost is low; Replace fabricated metals with plastic article, this is the trend of era development, and this technology makes full use of combining of vacuum technique and plastic material, will make heating pipeline enter brand-new epoch.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model.

As shown in the figure, one plastic inner pipe 4 is installed in plastic outer tube 3, said outer tube 3 aligns with interior pipe 4 one ends and the end face between two pipes is installed a ring sealing plate 6, there is the closely-pitched internal thread 1 that connects usefulness the pipe the inside in said, said outer tube 3 stretches out pipe closely-pitched outside thread coupling head 7 in the other end of interior pipe 4, one ring sealing plate 6 is installed between the end face of said outer tube 3 and interior pipe 4, be evacuated vacuum chamber 5 between pipe and the outer tube in said, dunnage 2 is installed in said vacuum chamber, two symmetries of said dunnage, two adjacent dunnages are criss-crossing and distribute, and the pipe collar of reinforing function can be installed in the connection place of said pipeline and pipeline.During installation, as long as the internal and external threads between the tube and tube connects, body can be made straight tube, bend pipe or pipe joint etc., and adaptive capacity is strong.
