There are many factors that affect the life of the solenoid valve products, corrosion of the solenoid valve is one of the important factors. Extend the life of the solenoid valve to improve the safety of the project, solenoid valve anti-corrosion is an important consideration. Solenoid valve products how to effectively protect the purchase of what precautions? You need to know the following methods.

Select corrosion-resistant materials according to media type

In the actual production and use, the solenoid valve is facing a variety of types of media, even the same medium, in the pressure, temperature and concentration of different circumstances, the corrosion rate of the material are also different. For example, aluminum is highly corrosive in concentrated nitric acid at concentrations above 80%, but corrosion is not severe in medium and low concentrations of nitric acid. While the carbon steel in the concentration of 50% sulfuric acid corrosion in the most serious, when the concentration reached 90% or more, the corrosion has declined sharply. Therefore, the purchase of electromagnetic valve products, you can analyze the specific types of media, as well as different concentrations of media on the degree of corrosion of the material, but also directly to the manufacturers for consultation.

Select corrosion resistant solenoid valve

Corrosion-resistant solenoid valves are specifically designed for use with corrosive media solutions. Many corrosion-resistant solenoid valves use non-metallic materials as contact surfaces for solenoid valves and media. Such as natural rubber, polytetrachlorethylene and other materials, not only have good corrosion resistance characteristics, as long as the project environment pressure, temperature consistent with the characteristics of the material, but also played a role in saving precious metals. For example, Shanghai Ju Liang as a domestic high-end solenoid valve manufacturers, its products are not only metal materials, corrosion resistance of electromagnetic valve equipment, as well as the use of non-metallic materials processing media and cavity wall contact, the customer can according to their actual conditions for procurement, Can also be made to the giant custom.

Solenoid valve surface treatment

Solenoid valve surface treatment can be divided into thermal spray and spray paint. Thermal spraying is one of the techniques for adding a protective layer to the surface of the device. Thermal spraying is the use of high energy density heat source, such as gas combustion flame, arc, plasma arc, electric, gas explosion, etc., the metal or non-metallic materials heated and melted, sprayed into the atomized form of the basic surface, Spray coating. Thermal spraying can improve the corrosion resistance of the electromagnetic valve surface, wear resistance, high temperature and other characteristics, to extend product life.

Spray paint is a more common method, the coating is non-metallic materials, coated on the metal surface or cavity, can effectively cut off the media and the atmosphere, to achieve the purpose of corrosion.

Control the corrosive environment

Control of the corrosion environment is mainly for the working environment where the solenoid valve, for example, can effectively control the environment of dust, water vapor, smoke and toxic gases, to keep the environment clean and dry.

Shanghai Ju Liang is the leading high-end valve industry manufacturers, the company's products include pneumatic valves, solenoid valves, electric valves, regulating valve, angle seat valve, self-control valve and ordinary valves and other models of products, has become a national key projects Build important partners.
