Abstract

The invention relates to a pressure-bearing type plastic liner, a production method and a solar water heater using the liner. The pressure-bearing type plastic liner comprises a liner body and end covers arranged on two sides of the liner body. The liner body comprises a first plastic layer, a net-shaped rib and a second plastic layer from inside to outside. The end covers are made of plastic materials. The pressure-bearing type plastic liner has the advantages that the liner body and the net-shaped rib are combined, the plastic linear is combined with a water inlet pipe, a water outlet pipe and a connection part to be formed integrally, work procedures are simplified, energy, time and labor cost are saved, a locating ring is embedded at the position of the end cover on one side of the plastic liner, a circle of screw holes are formed in the locating ring, an auxiliary heating device is in sealing connection with the locating ring through the screw holes and the sealing pad, sealing performance is good, combination is firm, pressure bearing performance is improved, and 20kg bearing pressure can be guaranteed.

Description

technical field

[0001] The invention belongs to the field of solar water heaters, and relates to a pressure-bearing plastic liner, a production method and a solar water heater using the liner. Background technique

[0002] At present, most of the inner tank materials of solar water heaters on the market are made of stainless steel. Stainless steel has good corrosion resistance, but in the process of processing, the joints of the inner tank need to be welded, and the quality of the welded parts affects the anti-corrosion performance of the inner tank.

[0003] In some areas of our country, the water quality is relatively poor, and the concentration of chloride ions is high. During use, the stainless steel liner often corrodes at the welding seam, and leakage occurs, which affects the life of the liner.

[0004] The plastic liner of the wall-mounted solar water heater adopts cold-rolled steel blanking, coiling, welding, end cap forming, end cap welding, polishing and deburring...
