Abstract
A glass vacuum solar collecting tube comprises an inner glass tube and an outer glass tube which are coated with selective absorption coating layers; the nozzle end of the glass vacuum solar collecting tube is made as a threaded structure, and the thread can be continuous or discontinuous. The threaded structure can be directly made as a threaded interface on the glass parent material of the glass vacuum solar collecting tube; or, metal material can be processed into thread, and then the metal material and the glass of the glass vacuum solar collecting tube are mutually fused and connected as a whole. The diameter of the thread at the nozzle can be equal to or less then the diameter of the outer glass tube. The connecting thread can be the connecting external thread arranged on the outer glass tube, or can be the connecting internal thread arranged on the inner glass tube. The connection between the glass vacuum solar collecting tube and the water tank of a solar water heater is firm and reliable, and can bear pressure.
Description
Technical field
The utility model relates to a kind of solar utilization technique, particularly a kind of glass vacuum solar collector tubes.
Background technology
At present, the shape and structure of employed glass vacuum solar collector tubes all is the vacuum structure that is made of inside and outside two-layer cylindrical glass tube in the solar water heater.It is simple in structure, and is easy to manufacture, and it and solar water heater connected mode are card edge type, and this connected mode is insecure, unreliable, can not bear pressure.When solar water heater had pressure, glass vacuum solar collector tubes broke away from from solar water heater easily, causes solar water heater to leak.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of glass vacuum solar collector tubes that is connected with water-heater water tank firm and reliable connection, realization pressure-bearing.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of glass vacuum solar collector tubes, comprise the inner glass tube and the cover glass pipe that are coated with coating for selective absorption, be characterized in: the nose end at thermal-collecting tube is provided with connecting thread.
The technical problems to be solved in the utility model can also come to realize that further described connecting thread is the connection external screw thread that is located on the cover glass pipe by the following technical programs.
The technical problems to be solved in the utility model can also come to realize that further described connecting thread is the connection internal thread that is located on the inner glass tube by the following technical programs.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, is provided with metallic sheath at the nose end of thermal-collecting tube, and described connecting thread is arranged on the metallic sheath.
The technical problems to be solved in the utility model can also come to realize that further described connection external screw thread is continuous thread or intermittent screw thread by the following technical programs.
The utility model is compared with prior art made helicitic texture at the nose end of glass vacuum solar collector tubes, and its screw thread can be a continuous thread, also can be intermittent screw thread.Guarantee the firm and reliable connection of glass vacuum solar collector tubes and solar water heater water tank, can bear pressure.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
The specific embodiment
A kind of glass vacuum solar collector tubes comprises the inner glass tube 2 and the cover glass pipe 3 that are coated with coating for selective absorption, makes helicitic texture at the nose end of glass vacuum solar collector tubes, and its screw thread can be a continuous thread, also can be intermittent screw thread.Helicitic texture can directly be made hickey on the base glass material of glass vacuum solar collector tubes; Also can become screw thread, then the mutual welding of the glass of metal material and glass vacuum solar collector tubes be linked into an integrated entity with metal material processing.Mouth of pipe diameter of thread size can equal and less than the cover glass tube diameter dimension.Connecting thread 1 can be provided in a side of the connection external screw thread on the cover glass pipe 3.Also can be provided in a side of the connection internal thread on the inner glass tube 2.
Claims (5)
1. a glass vacuum solar collector tubes comprises the inner glass tube (2) and the cover glass pipe (3) that are coated with coating for selective absorption, and it is characterized in that: the nose end at thermal-collecting tube is provided with connecting thread (1).
