The among the outer sheathing pipe and the outer sheathing nuts is a taper thread surface, and two lining pipe plugs are arranged in a lining of the heat collecting connecting pipe. The contact surface among the heat collecting connecting pipe and the two lining pipe plugs is a taper thread surface, and a through hole which is provided with folding lines which are arranged on the prophetical wall of the through hole is arranged in the center of the lining pipe plugs. The utility model can lead vacuum solar heat collecting pipes to be spliced to form a long vacuum solar heat collecting pipe, with the advantages of simple structure, convenient splicing and reliable operation.

Description

Novel evacuated solar energy heat collection pipe pipe joint

Technical field

The utility model technology relates to solar energy heating pipe manufacturer, combination, installation, debugging to be used, directly conjuncted, supporting with building industry, for the building is given up, hotel central heating system engineering has been opened up a new road.

Background technology

Existing vacuum solar heat-collecting pipe all is a single tube, and its length is no longer than 3 meters.Therefore, roofing just must have a water tank within 3 meters, and accounted for many heat collector surfaces of roofing of numerous water tanks are not fully utilized the plane of illumination of roofing.In addition, the structure of single tube makes it and water tank that a lot of interfaces be arranged, and makes many costs of part height.If short vacuum solar heat-collecting pipe is stitched together, become very long vacuum solar heat-collecting pipe, just can reduce the water tank number on the roofing, utilize the illumination of roofing fully, and help the large tracts of land installation.But existing pipe joint is not used on the butt joint of the vacuum solar heat-collecting pipe of glass.

Summary of the invention

The purpose of this utility model is: a kind of novel evacuated solar energy heat collection pipe pipe joint is provided, and it can be stitched together short vacuum solar heat-collecting pipe, forms long vacuum solar heat-collecting pipe, and simple in structure, and splicing is convenient, reliable operation.

The purpose of this utility model realizes by following scheme: novel evacuated solar energy heat collection pipe pipe joint is characterized in that:

It comprises outer socket pipe, cap nut, and thermal-arrest is taken over and the bushing pipe plug;

Outer socket pipe has two cap nuts outward, and the contact-making surface between outer socket pipe and the cap nut is the taper thread face;

Thermal-arrest is taken in the lining two bushing pipe plugs, thermal-arrest take over and two bushing pipe plugs between contact-making surface be the taper thread face; The center of bushing pipe plug is the through hole that a perisporium has broken line.Beneficial effect

The utlity model has following characteristics:

1, adjustability is good, the energy flexible modulation;

2, tightness is good;

3, versatility is good, and is easy to assembly;

4, can make full use of existing scale (being generally 2 meters long) vacuum heat collection pipe, connect into the random length size, meet consumers' demand.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.Wherein, 1 outer socket pipe, 2 cap nuts, 3 thermal-arrest bushing pipes, 4 bushing pipe plugs, 5 regular hexagon endoporus, 6 tapered treads, 7 tapered treads.

Fig. 2 is the part drawing among Fig. 1.

Fig. 3 is the user mode schematic diagram of the utility model embodiment.Wherein, the first pipe of 8 thermal-arrests, 9 thermal-arrest intervalves, 10 thermal-arrest tail pipes, 11 adhesives.

Concrete embodiment

Embodiment of the present utility model as shown in Figure 1.This joint has six parts, i.e. 1,2 cap nut 2 of 1 outer socket pipe; 3,2 bushing pipe plugs 4 of 1 thermal-arrest bushing pipe.There is tapered tread 6 outside of outer socket pipe 1, and cap nut 2 has corresponding with it tapered tread; The inner face of thermal-arrest bushing pipe 3 has tapered tread 7, and bushing pipe plug 4 has corresponding with it tapered tread; There is regular hexagon endoporus 5 at the center of bushing pipe plug 4, can be used for the assembly tool rotation.

User mode is seen Fig. 3.During installation, earlier thermal-arrest bushing pipe 3 two are put in 4 rotations of two bushing pipe plugs it is become one, again 2 rotations of two cap nuts are contained in outer socket pipe 1 two it is become one; One end plug of thermal-arrest bushing pipe 3 is gone in the thermal-arrest tail pipe 10, an end of outer socket pipe 1 is enclosed within on the thermal-arrest tail pipe 10, again will thermal-arrest intervalve 9 insert between thermal-arrest bushing pipes 3 and the outer socket pipe 1 and dock with thermal-arrest tail pipe 10; Stretch into regular hexagon endoporus 5 with instrument and rotate the bushing pipe plug 4 of inner ends, make being close on thermal-arrest tail pipe 10 and thermal-arrest intervalve 9 inwalls of thermal-arrest bushing pipe 3, rotary sleeve nut 2 is pressed on the outer wall of thermal-arrest tail pipe 10 and thermal-arrest intervalve 9 outer socket pipe 1.Method continues the first pipe 8 of butt joint thermal-arrest like this.

All can coat rubber polymer as adhesive in each junction and contact-making surface.

Vacuum between the first pipe 8 of thermal-arrest, thermal-arrest intervalve 9 and the thermal-arrest tail pipe 10 can be as shown in the figure separately independently, also can lead to, and is connected as a single entity; Its vacuum be after two groups of thermal-arrest Pipe joints connect again vacuum-pumping and sealing form.

Outer socket pipe 1 and thermal-arrest bushing pipe 3 are selected beryllium-bronze material for use.

Claims (1)

1, novel evacuated solar energy heat collection pipe pipe joint is characterized in that:

It comprises outer socket pipe, cap nut, and thermal-arrest is taken over and the bushing pipe plug;

Outer socket pipe has two cap nuts outward, and the contact-making surface between outer socket pipe and the cap nut is the taper thread face;

Thermal-arrest is taken in the lining two bushing pipe plugs, thermal-arrest take over and two bushing pipe plugs between contact-making surface be the taper thread face; The center of bushing pipe plug is the through hole that a perisporium has broken line.
