Galvanized steel sheet water heater antirust water tank and corrosion prevention method thereof

Abstract

The invention discloses a galvanized steel sheet water heater antirust water tank. According to the galvanized steel sheet water heater antirust water tank, a zero line / fire line detection module is additionally arranged, and meanwhile, when the galvanized steel sheet water heater antirust water tank is stopped from being heated, the purpose of rust corrosion prevention of the heating water tank is achieved through a mode of connecting a heating tube with a zero line of an external power supply. The galvanized steel sheet water heater antirust water tank has the advantages of slowing the oxidation process of a metal zinc welding line of the galvanized steel sheet water heater antirust water tank, prolonging the service life of the heating water tank and overcoming the defect of easy rust corrosion of the galvanized steel sheet water heater antirust water tank and is not easy to subjected to rust corrosion and economic and convenient to machine; and meanwhile, the manufacturing cost is low, and the cost performance of the water tank is improved.

Description

technical field

[0001] The invention relates to a galvanized steel plate water heater water tank, in particular to a galvanized steel plate water heater anti-rust water tank and an anti-rust method thereof. Background technique

[0002] At present, the materials used for heating water tanks on the market mainly include galvanized steel sheets and enamel, each of which has its own advantages and disadvantages.

[0003] The heating water tank made of enamel material has stable chemical properties, and the heating water tank made of it eliminates the problem of rust, but the technical difficulty of the enamel heating water tank is high and the manufacturing cost is high.

[0004] The heating water tank made of galvanized steel plate has the advantages of high strength, easy processing, and economy, but it also has the disadvantage of being easy to rust. Among them, the neglect of the "phase detection" (single-phase 220V) protection function leads to the shortcomings of easy ru...

Examples

Embodiment

[0018] like figure 1 , figure 2 The antirust water tank of a galvanized steel water heater includes: a heating pipe and a control module, a heating pipe control switch, a zero live wire detection module and an alarm module.

[0019] The connection relationship of the above components is as follows:

[0020] The control module is connected with the heating tube control switch, the zero live line detection module and the alarm module; the heating tube control switch is located between the heating tube control switch and the heating tube; the external power input line is connected with the zero live line detection module. Wherein, the zero live line detection module includes: a neon tube, a photoresistor, a load resistor R1 and a load resistor R3; the neon tube is opposite to the photoresistor and is located in a closed space, and one end of the neon tube is connected to an external power supply after the load resistor R1 is connected in series. The other end is connected to t...
