Embodiment Construction

[0025] figure 1 , figure 2 , image 3 A structural form of an all-plastic pressurized double-circulation double-barreled water tank liner is jointly described. The liner is made of polymer material, or modified polymer material, or reinforced polymer material, or composite polymer material, and there are reinforcing layers 3 and 5 in the wall of end cap 2, and there is a curved plate 22 on end cap 2 , the end cover 2 has an annular groove, a cold water inlet pipe 31, a hot water outlet pipe 28, a pipe 4, an electric water heater installation pipe 28 and 31, a vacuum pipe jack 23, and an exhaust pipe 30 is arranged on the annular groove of the end cover 2. One end of the tube 4 on the cover 2 communicates with the upper part of the water tank 15, and the other end communicates with the lower part of the water tank 13. There are reinforcement layers 12 and 14 in the wall of the end cover 11, and there are vacuum tube jacks 17 on the end cover 11. , the end cover 11 has an an...

Abstract

The invention discloses an all-plastic pressure-bearing dual-cycle double-barrelled water tank liner, comprising an end cover and a water tank. An annular groove on the end cover is connected with the water tank to form an annular hole, and the annular hole is communicated with the holes in the water tanker wall and is communicated with the outside via a pipe of the annular groove. Multiple holes in the water tank wall are connected in parallel to form a circular channel, the circular channel has a large total cross section, and the circular medium has very low flow resistance, thus laying a foundation for realizing the working state of heating by natural circulation. Due to multiple water containers of the liner, the water mixing phenomenon can be prevented in the use process of the water heater. In the invention, the heat exchange surface is big enough, thus the heat resistance is small, the heat exchange temperature is low, the heat exchange surface is prevented from scaling, and higher heat transfer efficiency can be maintained forever. The liner in the invention is mainly made from a polymer material and has the advantages of long service life, high reliability, simple production process, capability of large-scale industrialized production and wide market prospect, a great quantity of metal raw materials are saved, and the system manufacturing cost is greatly lowered.

Description

Technical field [0001] The invention relates to a water tank liner, in particular to an all-plastic pressurized double-circulation double-tube water tank liner. Background technique [0002] At present, most of the heat preservation water tanks used for solar water heaters and electric water heaters are made of stainless steel inner tanks. Due to the intergranular corrosion problem in the welds of stainless steel inner tanks, the short service life is an unsolved global problem. Although steel plate enamel inner tanks have been used in recent years at home and abroad However, the processing technology of the enamel liner is high, and air bubbles or pinholes are likely to occur during the production process. At the same time, the enamel is relatively brittle, and vibration and collision are prone to scale explosions. In addition, the enamel will gradually dissolve and peel off in hot water. Technically It is called "boiling water weightlessness" phenomenon, which makes it dif...
