DC3.7V solenoid normally closed valve for body massager

With the rapid development of the food industry, vacuum packaging machines play an increasingly important role in food preservation and extending shelf life. As a key component in the vacuum packaging machine, the performance of the micro air valve directly affects the packaging effect. This article will focus on the application, working principle, advantages and challenges of micro air valves in vacuum packaging machines, as well as future prospects.

How micro air valves work in vacuum packaging machines？

Micro air valves are mainly composed of valve body, valve core, spring and sealing gasket. Its working principle is to control the on-off gas flow by adjusting the position of the valve core. During the vacuum packaging process, the mini air release valve is first opened to communicate the inside of the packaging material with the atmosphere, and then the gas inside the packaging material is extracted through a vacuum pump to form a negative pressure to achieve the packaging effect. During the inflation process, the mini air control valve is also opened first to allow the inside of the packaging material to communicate with the atmosphere, and then the gas is filled inside to form a positive pressure to achieve encapsulation effect.

Application of micro Normally Closed Air Valve in vacuum packaging machine

Micro air valves mainly play a role in controlling gas flow in vacuum packaging machines. Specifically, the applications of micro air valves mainly include the following aspects:

1. Vacuuming: During the vacuuming stage, the micro air valve is opened to communicate the inside of the packaging material with the atmosphere, and then the gas inside the packaging material is extracted through a vacuum pump to form a negative pressure to achieve the packaging effect.

2. Inflation: During the inflation stage, the Micro Solenoid Air Valve is also opened first to allow the inside of the packaging material to communicate with the atmosphere, and then the gas is filled into the inside of the packaging material through a gas compressor to form a positive pressure to achieve the packaging effect.

3. Recycling: During the vacuum packaging process, the precise control of the micro air valve allows the gas to be recycled and improve work efficiency.

Technical Specification

Advantages and challenges of micro valves

1. Advantages: Dc Micro Air Valve has the advantages of small size, light weight, compact structure, easy installation, etc., and can adapt to various space constraints. In addition, micro air valves are usually made of corrosion-resistant, high-strength materials such as brass or stainless steel, which can ensure long-term stable operation.

2. Challenges: Although micro air valves have many advantages, they still face some challenges in practical applications. For example, micro air valves have high control accuracy requirements, and the position of the valve core needs to be accurately adjusted to control the gas flow. In addition, micro air valves have strict sealing performance requirements and need to maintain good sealing performance in harsh environments such as high temperature, high pressure, and corrosion.

Dimension Structure

What materials are micro valves made of?

Normally Close 2-Way Solenoid Valve is a small device used to control gas flow, usually composed of the following materials:

1. Valve body: usually made of metal materials, such as alloy, stainless steel or brass, with good sealing performance and pressure resistance.

2. Valve core: usually made of metal or non-metal materials, such as alloy, stainless steel, nylon, etc., with wear resistance, corrosion resistance, high temperature resistance and other characteristics.

3. Spring: usually made of stainless steel, used to control the opening and closing of the valve core and adjust the air flow.

4. Gasket: Usually made of rubber or fluororubber, it has good sealing performance and high temperature resistance.

5. Other accessories: such as bolts, nuts, etc., used to fix and connect various components of the Mini Solenoid Air Valve.
