How to design Manual Carbon Dioxide Valve to cope with high pressure environment?

1. Selection of high pressure resistant materials
The design of Manual Carbon Dioxide Valve should start with the selection of materials. Under high pressure environment, the material of the valve must have sufficient strength and pressure resistance to resist possible damage under long-term high pressure. Common materials such as stainless steel and brass are widely used in the manufacture of carbon dioxide valves.

Stainless steel: Stainless steel has good corrosion resistance and high strength, and can withstand the impact of carbon dioxide gas under high pressure, while also coping with the impact of environmental factors on the valve.

Brass: Brass has mechanical strength and corrosion resistance, especially suitable for occasions with high pressure and frequent operation. Brass valves can effectively prevent high pressure carbon dioxide from damaging the valve body.

2. Design and strengthening of valve structure
In order to ensure the safety of the valve under high pressure environment, the structural design of Manual Carbon Dioxide Valve is crucial. Valves in high pressure carbon dioxide systems must have sealing and pressure resistance to prevent gas leakage or failure due to excessive pressure.

Sealing design: The sealing part of the Manual Carbon Dioxide Valve usually uses high-quality seals. These sealing materials can effectively prevent carbon dioxide leakage and maintain stable sealing performance under high pressure.
Valve body reinforcement: In order to improve the valve's tolerance under high pressure, the design of the valve body needs to consider the pressure distribution problem. The flow channel and contact surface inside the valve are specially strengthened to ensure that there is no damage or deformation during the flow of high-pressure gas. In particular, the joint part of the valve is often thickened to enhance its pressure resistance.

3. Pressure regulation and safety protection mechanism
Under high pressure environment, the flow change of carbon dioxide gas may pose a potential threat to the safety of the system. Therefore, the Manual Carbon Dioxide Valve needs to be equipped with a variety of safety protection mechanisms during design to ensure that the system can still operate safely under high pressure.

Pressure relief device: In order to avoid equipment failure or gas leakage due to excessive pressure, many Manual Carbon Dioxide Valves are equipped with built-in pressure relief devices. When the system pressure exceeds the set value, the valve can automatically release part of the gas to prevent equipment overload and ensure the long-term safe use of the equipment.

Overpressure protection function: In addition, some Manual Carbon Dioxide Valves are designed with overpressure protection function. This function can protect the equipment from damage by automatically cutting off the gas flow path or releasing excess pressure when the system pressure is too high.

Backflow prevention design: Manual Carbon Dioxide Valves also often integrate backflow prevention design to ensure that CO2 will not flow back due to reverse pressure when the valve is closed. This is essential to prevent system contamination or control unstable gas flow, especially in applications such as medical gas and food production that require extremely high gas purity.

4. Flow control accuracy under high pressure conditions
Under high pressure conditions, carbon dioxide valves need to accurately adjust gas flow, and high pressure conditions often make flow control more difficult. Manual Carbon Dioxide Valve can provide high-precision flow control while ensuring safety through precise structural design.

Valve opening and closing degree adjustment: Manually operated valves can control flow by finely adjusting the opening and closing degree. Under high pressure conditions, precise manual control allows operators to ensure accurate regulation of carbon dioxide flow without fully opening the valve.

Stable flow control: Through high-precision valve design, the Manual Carbon Dioxide Valve can provide stable gas flow control to avoid unstable flow caused by gas pressure fluctuations or improper operation. This is especially important for some precision processes or laboratory applications, where slight changes in CO2 flow may affect the final result.
