Why can a micro water valve be used as air valve,but micro air valve cannot be used as water valve

The reason why micro water valves can be used as micro air valves is because they have many similarities in structure, principle, and materials.

First of all, micro water valves and micro air valves are devices used to control the flow of fluid or gas. Their basic structures are composed of a valve and a control device. The valve can be opened or closed through the control device to control the flow of fluid or gas. flow.

Secondly, both micro water valves and micro air valves need to take factors such as the pressure and flow rate of the fluid or gas into consideration. They all need to have certain pressure resistance and corrosion resistance to ensure normal operation under high pressure and corrosive media.

Micro water valves and micro air valves also have many similarities in terms of manufacturing materials, size, connection methods, etc. Many micro water valves and micro air valves use similar materials, such as alloy casing, back cover, spring, stainless iron core, ABS nozzle, etc., and the size and connection methods are often similar.

However, the reasons why micro air valves cannot be used as water valves are:

1. The seals of micro air valves usually use rubber or other elastic materials. These materials have poor corrosion resistance to water. They are prone to aging, deformation or corrosion when exposed to water for a long time, resulting in reduced sealing performance or failure. Moreover, the seal is installed inside the iron core with glue, so it cannot withstand the impact of water quality.

2. The seals of micro water valves are usually made of silicone. These materials are chemically stable and chemically resistant, and the seals are machine-covered and can withstand water impact.

3. The structural design of micro air valves is usually designed based on the characteristics of the gas medium, such as large gas fluidity and wide pressure fluctuation range. However, the characteristics of water medium such as small fluidity and small pressure fluctuation range are different from those of gas media. Therefore, the structure of the micro air valve may not be suitable for use with water media.
