YQT-341 Carbon Dioxide Pressure Reducer, Single-stage Double-gauge Pressure Reducing Valve, Explosion-proof and Anti-vibration National Standard Pressure Gauge

Carbon Dioxide Pressure Reducer, Single-stage Double-gauge Pressure Reducing Valve, Explosion-proof and Anti-vibration National Standard Pressure Gauge YQT-341

### Product Overview

- **Name and Model**: This product is named the carbon dioxide pressure reducer, with the model YQT-341. It is a device specifically designed for reducing the pressure of carbon dioxide gas and plays a crucial role in application scenarios that require precise control of carbon dioxide gas pressure in numerous fields such as industrial production and laboratory research.

- **Overall Structural Features**: This pressure reducer adopts a single-stage pressure reduction structure, which has the advantages of relatively simple structure and lower cost. Meanwhile, it is equipped with a double-gauge design. One gauge is used to display the high pressure inside the carbon dioxide gas cylinder, and the other is used to display the low pressure after pressure reduction, making it convenient for users to intuitively understand the changes in gas pressure and thus conduct more precise pressure adjustment and monitoring.

### Performance Characteristics

- **Explosion-proof and Anti-vibration Performance**: Considering the potential safety risks when carbon dioxide gas is used in some specific environments, this pressure reducer has explosion-proof and anti-vibration functions. Its outer shell and key components have undergone special design and treatment, which can effectively prevent explosion accidents caused by external impacts, vibrations or possible fire sources and ensure its safe and stable operation under various complex and harsh working environments.

- **Compliance with National Standards**: The YQT-341 carbon dioxide pressure reducer is manufactured in strict accordance with national standards and meets the requirements stipulated by national standards in multiple aspects such as pressure accuracy, sealing performance and material selection. This not only guarantees the product's quality and performance reliability but also enables it to be well compatible with other equipment and systems that meet national standards, providing users with a unified and standardized usage experience.

### Working Principle

When high-pressure carbon dioxide gas enters the pressure reducer from the gas cylinder, it first acts on the pressure reducing valve. The pressure of the gas overcomes the acting force of components such as the adjusting spring and pushes open the pressure reducing valve, allowing the carbon dioxide gas to enter the low-pressure chamber. As the gas pressure in the low-pressure chamber gradually increases, it will push elastic components such as the diaphragm to deform. Through the linkage mechanism, feedback is given to the pressure reducing valve, causing its opening degree to gradually decrease until a balanced state is reached. At this time, the carbon dioxide gas is output at a stable set pressure and supplied to the subsequent equipment for use.

### Component Details

- **Pressure Reducing Spring**: It is one of the key components for the pressure reducer to achieve pressure adjustment. By changing the compression degree of the spring, the opening degree of the pressure reducing valve is adjusted, thereby controlling the pressure reduction degree and output pressure of the carbon dioxide gas. Its material and elastic coefficient have been carefully selected and designed to ensure stable performance during long-term use.

- **Diaphragm**: As an important element for sensing pressure changes and transmitting signals, the diaphragm needs to have good elasticity and corrosion resistance. It can accurately sense the tiny changes in the gas pressure in the low-pressure chamber and promptly convert these changes into mechanical displacements. Through the linkage mechanism, it acts on the pressure reducing valve to achieve precise control of the output pressure.

- **Pressure Reducing Valve**: It directly controls the flow and pressure reduction process of carbon dioxide gas. Its sealing performance and adjustment accuracy are crucial to the overall performance of the pressure reducer. The design and manufacturing process of the valve ensure smooth and precise pressure reduction operations under different pressure conditions and also have good wear resistance and corrosion resistance to extend its service life.

- **Pressure Gauge**: As mentioned above, the two pressure gauges in the double-gauge design are respectively used to measure the high pressure and the low pressure. The accuracy of the pressure gauges meets the requirements of national standards and can accurately display the gas pressure values, providing reliable pressure references for users to conduct reasonable pressure adjustment and safety monitoring.

### Precautions for Use

- **Correct Selection and Installation**: When selecting the YQT-341 carbon dioxide pressure reducer, it is necessary to ensure accurate selection according to factors such as the actual flow rate, pressure range and usage environment of the carbon dioxide to be used. During installation, operations should be carried out strictly in accordance with the requirements of the product manual to ensure firm connections and good sealing to prevent gas leakage.

- **Regular Inspection and Maintenance**: To ensure the performance and safety of the pressure reducer, it is necessary to conduct regular inspections and maintenance on it. The inspection contents include the accuracy of the pressure gauges, the elasticity of the pressure reducing spring, the integrity of the diaphragm and the sealing performance of the pressure reducing valve. If any abnormal situations are found, the damaged parts or the entire pressure reducer should be replaced in time.

- **Safe Operation Specifications**: Although carbon dioxide itself is non-flammable, it can cause harm to the human body at high concentrations. During the pressure reduction process, it is still necessary to pay attention to safe operation. When opening and closing the gas cylinder valves, operations should be carried out slowly to avoid sudden pressure changes. The usage site should be kept well ventilated to prevent the accumulation of carbon dioxide. Meanwhile, it is necessary to keep away from fire sources and heat sources to avoid accidents.

In conclusion, the carbon dioxide pressure reducer, single-stage double-gauge pressure reducing valve, explosion-proof and anti-vibration national standard pressure gauge YQT-341 is a gas pressure reduction equipment with excellent performance, safety and reliability. It plays an important role in the application of carbon dioxide gas and provides stable and precise gas pressure control guarantees for production and research in related fields.
