What is the main role of Dry Valve in dry powder fire extinguishers? How does it control the release and injection of dry powder fire extinguishing agents?

Dry Valve, as the core component of dry powder fire extinguishers, undertakes the key task of controlling the release and injection of dry powder fire extinguishing agents. It is not only a decisive factor in whether the fire extinguisher can work effectively, but also an important barrier to ensure personnel safety and prevent accidental leakage.
First of all, the main function of the Dry Valve is to control the flow of dry powder fire extinguishing agent from the inside of the fire extinguisher to the nozzle. Under normal circumstances, the valve is in a closed state, and a tight seal is formed between the valve core and the valve body, effectively preventing the leakage of fire extinguishing agent. This design not only ensures the long-term stability of the fire extinguisher, but also avoids safety risks caused by misoperation or accidents.
When a fire occurs, the operator pushes the valve stem to separate the valve core from the valve body, thereby opening the valve channel. At this time, the dry powder fire extinguishing agent quickly flows through the valve channel to the nozzle under the action of internal pressure, and is accurately sprayed onto the fire source. This process not only requires the Dry Valve to respond quickly, but also requires it to accurately control the injection volume and direction of the fire extinguishing agent to achieve the best fire extinguishing effect.
The precise control mechanism of Dry Valve comes from its exquisite design and manufacturing process. The matching precision between the valve core and the valve body is extremely high, ensuring the valve's sealing when closing and smoothness when opening. At the same time, the operating force of the valve stem has also been carefully adjusted, which not only ensures the convenience of operation, but also avoids safety hazards caused by improper operation.
In addition, the material selection of Dry Valve is also crucial. It is usually made of corrosion-resistant and high-temperature-resistant materials to ensure good working performance in extreme environments. This material choice not only increases the service life of the Dry Valve, but also enhances its reliability and stability.
To sum up, Dry Valve plays a vital role in dry powder fire extinguishers. Its precise control mechanism and reliable performance ensure that the fire extinguisher can quickly and effectively extinguish fires at critical moments. At the same time, its sophisticated design and manufacturing process also enhance the safety and stability of the fire extinguisher, providing a strong guarantee for the safety of people's lives and property.
