Solar water heater tank liner seal head and mounting method

Abstract

The invention discloses a solar water heater tank liner seal head which structurally comprises a transverse protecting edge (1), a longitudinal bearing edge (2), a seal cover (3), a water pipe mounting port (4), a water pipe mounting port extending diameter (5). The solar water heater tank liner seal head is characterized in that the seal cover can be rectangular and circular, the longitudinal bearing edge is disposed on the periphery of the seal cover, an inclination angle of 1-3 degrees exits between the longitudinal bearing edge and the seal cover, the transverse protecting edge is disposed at the top end of the longitudinal bearing edge and of an annular shape, the space in the middle of the annular shape is formed by the transverse protecting edge and the seal cover, the transverse protecting edge comprises protecting lugs and a protecting edge body, the width of the protecting edge body is smaller than that of each protecting lug, the transverse protecting edge is parallel with the seal cover, the water pipe mounting port is formed in the middle of the seal cover. The solar water heater tank liner seal head has the advantages that equipment mounted with the seal cover is high in airtightness and corrosion resistance, long in service life, smooth and complete in appearance, and production can be performed on the basis of original equipment and materials.

Description

technical field [0001] The invention relates to the field of accessory devices for solar energy utilization in the heating field, in particular to a solar water heater connecting tank liner head and an installation method. Background technique [0002] Heads are widely used in fields such as filtration, heat exchange, and storage. However, depending on the size of the equipment and the requirements for sealing, there are great differences. The head technology of water heater storage tanks is relatively complicated and has The cost of some technologies is too high, and the service life of some technologies is too short. [0003] The Chinese patent with the patent number CN201120417028.7 discloses a head structure of the water heater liner. The head structure of the water heater liner includes a head and a flange. It is directly integrated on the head, which greatly reduces the product cost and processing cost of the inner tank head structure of the water heater. This techno...

Problems solved by technology

[0006] Patent No. CN201220029685.9, the utility model discloses a connection structure between the barrel in the water heater liner and the head, including the barrel in the liner and the head, the straight edge of the opening end of the head is bent inward along the circumference, and the The opening end of the barrel in the liner is described as a lap fit, and the straight edge of the opening end of the head is bent inward along the circumference. The technology of changing the head adopts the inner bending and the opening end of the barrel to form a welding space, which is convenient for welding. The whole process is still too complicated. Although it is convenient for welding, the inner bending and the opening end of the barrel need special separate processing, and it is impossible to complete the integrated one-time molding. The extra processing technology undoubtedly increases the process steps and virtually increases The processing time reduces the work efficiency and increases the cost of production at the same time, the technology is still not perfect

[0007] For the inner tank of the water storage device with a small volume, the cost of using the flange head is too high, and the equipment installation is complicated. However, the existing welding head has its own imperfect technology, poor corrosion resistance, short service life, and poor processing technology. Complicated problems, the present invention provides a solar water heater connected tank liner head and installation method, the present invention is simple in structure design, easy to process and produce, easy to install and use, scientific in structure, and can maximize the use of each structure in the installation accessories Maximize the perfect equipment performance, the processing cost of the equipment itself is low, the process flow is simple, the installed equipment has high sealing performance, high corrosion resistance, long service life, and smooth and intact appearance
