[0002] A pressure vessel refers to a device that contains liquid or gas and carries a certain pressure. The tank structure of the pressure vessel is the core component of this type of product. When the internal and external effects occur, the overall pressure-bearing performance of the tank will be unbalanced, and the shape of the tank body will change locally or even as a whole, which will cause the tank body to rupture, damage, severely deform or even explode, and the product will be scrapped as a whole.
[0003] In daily life, the liner of an electric water heater is a common pressure vessel. Quality and safety accidents such as rupture and leakage of the liner of the electric water heater and explosion of the liner often occur, causing personal injury and economic losses to consumers.
[0004] At present, for the inner tank of electric water heaters, in the product design process, it is generally based on experience, and the design of parameters such as the shape, structure, and thickness of the steel plate of the inner tank lacks theoretical basis and testing data support; in terms of product manufacturing and quality testing, the current general The best way is to verify whether it is qualified by the number of cycles of pressing

example 1

[0068] In this example, lead zirconate titanate is used as the piezoelectric nanomaterial, and 50 g of lead zirconate titanate nanomaterial is ultrasonically dispersed in deionized water to form a suspension, and then the surfactant trimethoxysilylmethyl is added to the above suspension. 50 g of propyl acrylate, and under the stirring condition of 800 r / min, the above mixture was refluxed for 4 h at a temperature of 150 °C. Use a high-speed centrifuge for centrifugation, discard the supernatant, and wash the obtained precipitate with absolute ethanol three times and dry at 60°C for 12h. 10 g of lead zirconate titanate nanomaterials and 10 g of surface-activated lead zirconate titanate nanomaterials were added to 10 g of photocurable resin, respectively, dispersed by ultrasonic for 5 min, and then allowed to stand for 5 h. like Figure 4 , Figure 5 As shown in the experiment, it was found that the lead zirconate titanate nanomaterial without surface activation treatment sett...

example 2

[0070] In this example, the piezoelectric nanomaterial is barium titanate, and 50 g of barium titanate nanomaterial is ultrasonically dispersed in deionized water to form a suspension, and then the surfactant trimethoxysilylmethacrylic acid is added to the above suspension 50 g of propyl ester, under the stirring condition of 1000r / min, the above mixture was refluxed at 150℃ for 4h. Use a high-speed centrifuge for centrifugation, discard the supernatant, and wash the obtained precipitate with absolute ethanol three times and dry at 60°C for 12h. 9 g of barium titanate nanomaterials and 9 g of surface-activated barium titanate nanomaterials were added to 3 g of light-curing resin, respectively, dispersed by ultrasonic for 5 min, and then allowed to stand for 5 h. like Figure 4 , Figure 5 As shown in the experiment, it was found that the barium titanate nanomaterial without surface activation treatment settled after standing for half an hour and settled at the bottom of the ...

example 3

[0073] In this example, lead zirconate titanate is used as the piezoelectric nanomaterial, and 50 g of lead zirconate titanate nanomaterial is ultrasonically dispersed in deionized water to form a suspension, and then the surfactant trimethoxysilylmethyl is added to the above suspension. 25 g of propyl acrylate, under the stirring condition of 1200 r / min, the above-mentioned mixed solution was refluxed for 5 h at a temperature of 180 °C. High-speed centrifuge was used for centrifugation, and the supernatant was discarded. The obtained precipitate was washed three times with absolute ethanol and dried at 60°C for 12 hours to obtain surface-activated lead zirconate titanate nanomaterials with good dispersibility. The above surface activated lead zirconate titanate nanomaterials were added to the photocurable resin respectively, the volume ratio of the two was 0.05:1, and the nanomaterials and the resin were thoroughly mixed uniformly by ball milling for 30 minutes to obtain the p...

Abstract

The invention discloses a pressure vessel, a manufacturing method and a stress detection system and method of the pressure vessel, and relates to the technical field of pressure vessels. The problem that traditional pressure vessels cannot avoid damage even exploding accidents caused by the inside and outside actions is solved, and the function of timely early warning and prompting is achieved. The pressure vessel comprises a vessel body, and the outer wall of the vessel body is coated with a piezoelectric composite layer. The pressure vessel is used for containing liquid or gas.

Description

technical field [0001] The present invention relates to the technical field of pressure vessels, in particular to a pressure vessel and a manufacturing method thereof, and a pressure vessel stress detection system and method. Background technique [0002] Pressure vessel refers to equipment that contains liquid or gas and bears a certain pressure. The tank structure of the pressure vessel is the core component of this type of product. The tank structure is subject to corrosion, wear, puncture, oxidation, instantaneous high pressure, and photothermal aging When the internal and external effects are applied, the overall pressure-bearing performance of the tank will be unbalanced, and the shape of the tank will be changed locally or even as a whole, which will lead to rupture, damage, severe deformation or even explosion of the tank, and the entire product will be scrapped. [0003] In daily life, the inner liner of electric water heater is a common pressure vessel. Quality and...
