Parameters and characteristics of medium pressure water mist nozzles

Fire is a common and dangerous accident. In order to effectively control and extinguish fires, fire extinguishing technology has received extensive attention and research. As an important part of modern fire extinguishing technology, medium-pressure water mist fire extinguishing nozzles play an important role in various application scenarios. This article will introduce the parameters and characteristics of medium-pressure water mist fire extinguishing nozzles and their performance in practical applications.

1. Parameter characteristics of medium pressure water mist nozzle

Medium-pressure water mist fire-extinguishing nozzle is a kind of fire-extinguishing equipment, and its parameter characteristics are crucial to effective fire-extinguishing operations. The following are some key parameter characteristics:

1. Working pressure: Medium-pressure water mist fire extinguishing nozzles usually work at higher working pressure, generally in the range of 1.2 to 3.5Mpa. This working pressure can not only confirm the degree of refinement of the water mist, but also confirm that the water mist can quickly reach the fire source, thereby achieving rapid fire extinguishing.

2. Flow range: Medium-pressure water mist fire extinguishing nozzles have a wide flow range, usually between 5 and 50 liters/minute. This makes the sprinkler suitable for fires of different sizes and severity, from small office fires to industrial plant fires, which can be effectively controlled.

3. Atomization effect: Compared with traditional high-pressure water guns, an obvious feature of medium-pressure water mist fire extinguishing nozzles is its excellent atomization effect. The particle size of water mist is usually between 50 and 200 microns. This small water mist particle can quickly evaporate and absorb heat, reducing the temperature of the fire source, thereby achieving the effect of rapid fire extinguishing.

4. Spray distance: The spray distance of medium-pressure water mist fire extinguishing nozzles is generally between 3 and 6 meters. This allows firefighting personnel to operate from a relatively safe distance, reducing risks during firefighting.

2. Application of medium pressure water mist nozzles

Medium pressure water mist fire extinguishing nozzles are widely used in many fields. The following are some main application fields:

1. Building fire protection: Medium-pressure water mist fire extinguishing nozzles are often used in fire protection systems inside buildings, such as commercial buildings, residential buildings, etc. Its rapid fire extinguishing effect and small spray distance make it excellent in indoor firefighting.

2. Industrial field: In industrial plants, fires often cause huge losses. Medium-pressure water mist fire extinguishing nozzles can extinguish fires in dangerous areas such as industrial equipment and chemical storage areas, effectively reducing fire risks.

3. Transportation: Medium-pressure water mist fire-extinguishing nozzles are increasingly used in transportation such as ships, trains, and automobiles, and can quickly extinguish fires in engine rooms and other areas.

4. Special environments: In some special environments, such as oil tank areas, nuclear power plants, etc., medium-pressure water mist fire extinguishing nozzles also play an important role. Its superior atomization effect can reduce the impact of fire on the environment.

3. Medium pressure water mist nozzle model

There are two main structural types of medium-pressure water mist nozzles, namely open nozzles and closed nozzles. There are certain differences in working principles and applications between the two. Commonly used models include the following:

1. Medium pressure water mist open nozzle model

XSW-T2.0/1.5、XSW-T2.5/1.5、XSW-T3.0/1.5、XSW-T3.5/1.5、XSW-T4.0/1.5、XSW-T4.5/1.5、XSW-T5.0/1.5、XSW-T5.5/1.5

Among them, XSW-T represents the fine water mist nozzle, the number immediately following it represents the flow coefficient, and the number after the flow coefficient represents the working pressure.

2. Medium pressure fine water mist closed nozzle model

XSW-T3.5/1.5-57℃φ2、XSW-T4.0/1.5-57℃φ2、XSW-T4.5/1.5-57℃φ2、XSW-T5.0/1.5-57℃φ2、XSW-T5.5/1.5-57℃φ2

Compared with the open nozzle, the medium pressure fine water mist closed nozzle model has an additional glass ball parameter, namely 57℃φ2, where 57℃ represents the temperature of the glass ball, and φ2 represents the diameter of the glass ball of 2mm.

As an important representative of modern fire-extinguishing technology, medium-pressure water mist fire-extinguishing nozzles have key parameters such as working pressure, flow range, atomization effect, and spray distance, making them perform well in multiple application fields. Through reasonable design and application, medium-pressure water mist fire extinguishing nozzles will play an increasingly important role in future fire prevention and control, protecting lives and property.
