Custom Fire Hose & Horn Manufacturers

Fire Hose & Horn plays a vital role in fire safety. Its main function is to efficiently transport the fire extinguishing agent from the inside of the fire extinguisher to the fire source. The design of the nozzle directly affects the spraying method, spraying range and spraying distance of the fire extinguishing agent, which are closely related to the efficiency and safety of fire extinguishing.
As the key channel connecting the valve and nozzle of the fire extinguisher, the Hose & Horn is responsible for quickly and effectively transporting various fire extinguishing agents (such as water, foam, dry powder, etc.) to the fire source. Design parameters such as the inner diameter, material and length of the nozzle have a significant impact on the flow rate and pressure of the fire extinguishing agent. For example, a small inner diameter may result in insufficient flow rate of the fire extinguishing agent, affecting the fire extinguishing effect, while the choice of material is directly related to the durability and corrosion resistance of the Hose & Horn.
The Horn design of the nozzle is also crucial, which determines the spraying pattern of the fire extinguishing agent. Common spraying patterns include atomized spraying and direct spraying. Atomized spraying disperses the fire extinguishing agent into fine water mist, increasing the contact area between the fire extinguishing agent and the air, thereby significantly improving the fire extinguishing efficiency. This mode is particularly suitable for extinguishing flammable liquid fires or electrical fires, because the fine water mist can effectively reduce the temperature and oxygen concentration. Direct injection is suitable for situations where concentrated firepower is required, and can exert a strong fire suppression force on the fire source in a short time.

Fire Hose & Horn Industry knowledge

Design and Application of Fire Hose & Horn
Fire Hose & Horn is the core component of fire extinguisher, and its design and spray mode directly affect the effect and efficiency of fire extinguishing. Ningbo Kaituo Valve Co., Ltd., with many years of industry experience, focuses on the research and development, production and export of fire fighting equipment, and is committed to providing high-quality Fire Hose & Horn and other fire fighting equipment to the global market.
DC spray mode
The DC spray mode is a fire extinguisher that sprays the extinguishing agent to the fire source in a concentrated and direct manner through the nozzle. This mode has significant efficiency and can quickly concentrate its strength to attack the initial fire. Due to its high spray pressure, the DC spray mode usually has a long spray distance, which enables it to effectively extinguish fires at a longer distance. At the same time, this mode is suitable for a variety of fire types, especially fires caused by the burning of solid materials, such as wood and paper.
Atomizing spray mode
The atomizing spray mode sprays the extinguishing agent into fine water droplets to cover the fire source in a mist form. The advantage of this mode is that it can increase the contact area between the extinguishing agent and the flame, thereby improving the fire extinguishing effect. When tiny water droplets come into contact with the flame, they evaporate quickly, taking away a lot of heat, lowering the temperature of the fire source, and achieving the purpose of extinguishing the fire. In addition, atomization spraying can also effectively reduce the concentration of harmful gases at the fire scene and ensure the safety of rescuers.
Foam spraying mode
The foam spraying mode uses the characteristics of foam fire extinguishing agents to spray foam onto the fire source through a nozzle to form a covering layer. Foam can form an isolation layer on the surface of the burning object, effectively preventing oxygen from contacting the flame, thereby achieving the effect of extinguishing the fire. This mode is particularly suitable for fires caused by liquid fuels, such as oils and chemicals, and can effectively control the spread of fire. In addition, modern foam fire extinguishing agents usually use environmentally friendly materials to reduce the negative impact on the environment.
Fine mist spraying mode
The fine mist spraying mode sprays the fire extinguishing agent in an extremely fine mist form, forming tiny water droplets to cover the fire source. The fine mist can evaporate quickly, taking away a lot of heat, and quickly lowering the temperature of the fire source. Compared with traditional water spraying, fine mist spraying can significantly reduce the damage of water to the surrounding environment and equipment, and is particularly suitable for water-sensitive places such as electronic equipment and libraries.
Choose the right spray pattern
When choosing the right spray pattern, multiple factors such as fire type, extinguishing agent properties, extinguisher design and on-site environmental conditions must be considered comprehensively. Ningbo Kaituo Valve Co., Ltd. fully considers the characteristics of different spray patterns in the design and manufacturing process of the nozzle to meet the diverse needs of customers. Our goal is to provide users with efficient and reliable fire extinguishing solutions to ensure that various fire challenges can be effectively responded to at critical moments.
The role of Fire Hose & Horn in different fire extinguishing agents
Fire Hose & Horn plays a key role in firefighting equipment, especially in the application scenarios of different types of fire extinguishing agents. Its design, materials and structure directly affect the efficiency and effect of fire extinguishing.
The main function of Fire Hose & Horn is to efficiently deliver fire extinguishing agents to the source of fire. The design of the nozzle includes its shape, diameter and spray pattern, which will have a significant impact on the flow characteristics of the fire extinguishing agent, which is directly related to the success rate of fire extinguishing. Reasonable nozzle design can optimize the spray angle and flow rate of the fire extinguishing agent, ensuring that it covers the fire source in the shortest time and maximizes the fire extinguishing effect.
Application of water-based fire extinguishing agents
Water-based fire extinguishing agents are one of the most commonly used fire extinguishing agents, and are particularly suitable for extinguishing fires caused by solid materials (such as wood, paper, etc.). In the application of water-based fire extinguishing agents, the role of the nozzle is to effectively spray water onto the flame in the form of a spray or a direct current.
The advantages of water-based fire extinguishing agents include:
Significant cooling effect: Water can quickly take away the heat of the flame and reduce the temperature, thereby effectively suppressing the development of the fire.
Economical and practical: Water is widely available as a fire extinguishing agent, with low cost, and is suitable for large-scale fire fighting.
Environmentally friendly: Water-based fire extinguishing agents are harmless to the environment and do not require special treatment after use, which meets the requirements of sustainable development.
Characteristics of foam fire extinguishing agents
Foam fire extinguishing agents are mainly used to extinguish liquid fires (such as oil fires). The nozzle sprays the foam fire extinguishing agent to the fire source through the foam spraying device to form a covering layer.
The main advantages of foam fire extinguishing agents are:
Isolating oxygen: The foam forms a protective film on the surface of the burning object, isolating oxygen and effectively extinguishing the flame.
Strong adaptability: Foam fire extinguishing agents are suitable for many types of fires, including liquid and solid fires, and have good versatility.
