Thread pressing and sealing device for large-diameter solar vacuum heat collecting tube

Abstract

The invention discloses a thread pressing and sealing device for a large-diameter solar vacuum heat collecting tube. The device comprises a machine frame; a positioning preheating mechanism, a sealingmechanism, a thread pressing mechanism and a pipe orifice trimming mechanism are sequentially arranged at one end of the machine frame in the direction of the solar heat collecting pipe. A manipulator device, which corresponds to and is coaxial with the positioning preheating mechanism, the sealing mechanism, the thread pressing mechanism and the pipe orifice trimming mechanism respectively, is arranged at the other end of the machine frame. The device is smart in design and reasonable in structure, and can replace original manual operation to manufacture the large-diameter vacuum solar collector tube. A manufactured vacuum heat collecting pipe is uniform in opening diameter and thread specification, so that the production efficiency is greatly improved. The daily output and the quality of the device are far higher than those of manual production. The device lays a foundation for large-scale production and rapid installation of solar equipment and reduction of cost and popularizationof solar energy, thereby realizing building energy conservation.

Description

technical field [0001] The invention relates to a sealing device for solar heat collecting tubes, in particular to a large-diameter solar vacuum tube capable of sealing large-diameter heat-collecting tubes, pressing threads, and trimming nozzles so that the caliber and thread specifications of the vacuum heat-collecting tubes are unified. The utility model relates to a heat collecting tube pressure thread sealing device, which belongs to the technical field of solar heat collecting tube sealing equipment. Background technique [0002] With the continuous improvement of our government's requirements for building energy conservation, the number of provinces in our country where solar water heaters are compulsorily installed on high-rise buildings continues to increase, and certain energy-saving effects have also been achieved. However, since most of the solar water heaters installed on buildings are balcony wall-mounted Solar water heaters and solar water heaters with roof int...

Problems solved by technology

[0004] However, since the key components of the window-type water tankless solar water heating system are thickened and thickened large-diameter vacuum solar collector tubes, and have threaded openings, it is easy to seal and bear pressure, and enhance the comfort of solar water heaters; however, The current thickened and thickened large-diameter solar vacuum heat collectors are handmade, resulting in different diameters of the vacuum heat collectors with threaded openings, not only low production efficiency, but also slow installation speed, high installation cost, and prone to water leakage.
