Embodiment Construction
[0026] In the following, the present invention will be further described by describing specific embodiments with reference to the accompanying drawings.
[0027] For one of the specific implementation methods, please refer to the attached Figure 1~3 .
[0028] A vacuum degree display device of a solar vacuum heat collecting tube, comprising a flange 1 of a stainless steel sealing tube 9, and further comprising:
[0029] An evaporable getter assembly 2; the evaporable getter assembly 2 consists of a getter box 2-1 for fixing the evaporable getter 4, and is fixed with the getter box 2-1 connected connecting rods 2-2;
[0030] The other end of the connecting rod 2-2 of the evaporable getter assembly 2 is connected and positioned with the flange 1 of the stainless steel sealing pipe 9, and the getter box 2-1 of the evaporable getter assembly 2 is arranged in In the vacuum layer ZKZ of the solar vacuum heat collecting tube, and the evaporable getter 4 directly faces the outside...

The invention discloses a vacuum degree display device of an evacuated solar collector tube. The vacuum degree display device comprises an evaporable getter assembly. The evaporable getter assembly is composed of a getter box used for fixedly containing an evaporable getter and a connecting rod fixedly connected with the getter box. The other end of the connecting rod of the evaporable getter assembly is connected with a sealing tube flange in a positioning mode. The getter box of the evaporable getter assembly is arranged in a vacuum layer of the evacuated solar collector tube, and the evaporable getter directly faces the outside of the evacuated solar collector tube. Under working conditions, the surface of the evaporable getter in a normal vacuum degree state is a bright mirror surface; when the vacuum degree is lost, as the loss degree of the vacuum degree is increased, the surface of the evaporable getter gradually becomes dim until off-white fine particles are formed on the surface of the evaporable getter, and therefore the vacuum degree of the evacuated solar collector tube is displayed. The vacuum degree display device has the advantages that the structure is simple, the layout position is reasonable, and the loss degree of the vacuum degree of the evacuated solar collector tube can be mastered by visually inspecting physical changes of the surface of the evaporable getter.
Description
technical field [0001] The invention relates to a vacuum degree display device of a solar vacuum heat collecting tube, which belongs to the technology of solar heat utilization equipment. Background technique [0002] The solar vacuum heat collector is located between the outer tube of the glass tube and the inner tube of the stainless steel tube, which is a vacuum layer for vacuuming. [0003] Due to the existence of the vacuum layer, the solar vacuum heat collecting tube can effectively improve and maintain its solar heat utilization efficiency. [0004] However, since the preparation of solar vacuum heat collecting tubes cannot be absolutely sealed, and the tube walls of the outer tube of the glass tube and the inner tube of the stainless steel tube are not absolute in blocking the delayed penetration of gas, the vacuum degree of the vacuum layer of the solar vacuum heat collecting tubes , will be gradually lost as time goes by, and this phenomenon of vacuum loss is inev...
