Evacuated collector tube with self-checking function

Abstract

The invention discloses an evacuated collector tube with a self-checking function, and belongs to the technical field of heat exchange parts, and the evacuated collector tube with the self-checking function comprises a solar vacuum tube and a built-in pipeline arranged on the solar vacuum tube. According to the descaling device, the descaling effect can be further improved through the designed descaling assembly, in the rotating process of the micro-expansion descaling pipe, a reciprocating lead screw can be driven to rotate in a lead screw sleeve, and under the combined action effect of torsion and thread meshing force, the lead screw sleeve can displace on the surface of the reciprocating lead screw; due to the fact that the two ends of the linkage shaft can rotate, the piston piece can be driven to conduct corresponding opening and closing actions, the heat exchange efficiency of a cold and heat source at the pipe opening of the solar vacuum pipe can be improved by means of the opening and closing actions of the piston piece, when the solar vacuum pipe breaks, the micro-expansion descaling pipe can pull the piston piece to be closed, and therefore the heat exchange efficiency of the cold and heat source at the pipe opening of the solar vacuum pipe is improved. Therefore, waste of water resources can be avoided.

Description

technical field [0001] The invention belongs to the technical field of heat exchange parts, and in particular relates to a vacuum heat collecting tube with a self-checking function. Background technique [0002] The solar vacuum tube is the core component of the solar water heater and is known as the "heart" of the solar water heater. The quality of the vacuum tube directly affects the service life and performance of the solar water heater. The rapid development of the solar industry has also driven the development of vacuum tube enterprises. It is because the patented technology around vacuum tubes is constantly innovating. On the other hand, vacuum tube companies and production lines have sprung up like mushrooms after a rain in recent years. At present, there are still some deficiencies in the use of existing vacuum heat collector tubes. After the solar vacuum tube is used for a period of time, due to the large amount of impurities in the water, the residual chlorine used...
