Fire Fighting Gun
1.Efficient Fire Suppression: Foam covers the fire source, cuts off oxygen supply, and quickly extinguishes flames.
2.Environmental Friendliness: Modern foam materials generally contain no harmful components, making them eco-friendly.
3.High Visibility: The foam creates a distinct visual effect, facilitating easy visual assessment of fire suppression progress.
4.Wide Applicability: Effectively addresses various types of fires, particularly those caused by liquid fuels.
Product Overview
A foam gun is a fire-fighting equipment that effectively generates foam to extinguish flames. It is mainly used at fire scenes, especially demonstrating remarkable effects in oil and chemical fires.

Main Fire-Fighting Components
1. Barrel
Function: Serves as the main spray channel for foam, stably delivering the mixed foam to the fire source through the barrel.
Material: Usually made of corrosion-resistant metal materials to ensure durability during use.
2. Handwheel
Function: Used to adjust the spray volume and speed of foam, enabling precise control based on actual conditions.
Design: Features a comfortable grip, firmly connected to the gun body, and allows for simple operation.
3. Gun Body
Function: The core structure of the entire foam gun, supporting other components and ensuring their stability.
Material: Generally made of high-strength alloy or plastic, with excellent pressure resistance and heat resistance.
4. Ball Valve
Function: Controls the inflow of water and foam concentrate, enabling quick opening or closing when needed.
Features: Responsive and well-sealed, effectively preventing leakage.
5. Suction Pipe
Function: Responsible for drawing foam concentrate from the mixing container for proportioning and mixing.
Design: Typically made of chemical corrosion-resistant materials to ensure reliability during long-term use.
6. KY65 Pipe Thread Connection
Function: Used to connect the foam gun to the water supply pipeline and foam concentrate supply pipeline, ensuring stable fluid transmission.
Design: Standardized interface for easy connection and compatibility, suitable for matching with multiple pipeline systems.
Working Principle
The working principle of the PQ series air foam gun is as follows:
1.Vacuum Pressure Difference
It utilizes an orifice plate to create a vacuum pressure difference through water flow velocity, which sucks in foam concentrate. The foam concentrate is then mixed with air before being sprayed.
2.Foam Solution Mixing
It can be used with various types of foam concentrate mixed at 3% or 6% load in the fire protection system, with the ball valve kept closed at this time.
It can also suck foam concentrate automatically when supplied with pressure water from the fire protection system, with the ball valve fully opened in this case.
3.Operational Precautions
The foam gun is equipped with a circular handwheel for operation and protection; the operator should firmly grasp the handwheel during use.
Note that the pressure of water or mixed solution supplied to the gun should be increased gradually, avoiding exceeding the operating pressure range to prevent injury to the operator.
4.Spraying Direction
Spray with the wind to ensure the best spraying effect.
