PROCEDURE AND DEVICE FOR MANUFACTURING WITH ADDITIVE MIXED FIRE EXTINGUISHING AGENTS

Proportioning valve and control means therefor

Foam production method, fire extinguishing method, and foam extinguishing appliance

A foam production method and use thereof in fire extinguishing, as well as a fire extinguishing method. The foam production method comprises mixing liquid nitrogen with a foaming material to produce foam by means of the foaming material. The foam production method pioneers using the method of mixing a gas produced in situ from liquid nitrogen with a foaming material. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials ...

A fire-fighting system in which a liquid chemical foamant is introduced into the water stream in varying amounts so as to maintain a predetermined percentage mixture irrespective of variations in the water flow includes a motor-driven pump where the motor is controlled over a first speed range by pulse width modulating the drive to the motor and over a second speed range, producing intermittent motion, by burst width modulating the drive signal when it is operating at its minimum pulse width modulated duty cycle. Using this technique the range of available motor speeds is extended well beyond that which can be achieved using pulse width modulation of the motor drive signal alone.

COMPRESSED AIR FOAM PUMP APPARATUS

Apparatus for mixing and applying particulate matter and foam

In an apparatus for applying rock dust with foam to a mine wall to suppress mine fires and prevent explosions, foam and air-entrained rock dust are separately conveyed to a combination nozzle and mixing device. The air-entrained rock dust moves axially through a passage into an enlarged chamber while foam moves through an array of openings surrounding the passage that direct the foam in a helical path. The helical movement of the foam, and the reduction of the velocity of the air-entrained rock dust resulting from its movement into the enlarged chamber, enhance mixing. The mixture passes from the enlarged chamber through a restricted nozzle to increase the velocity of the mixture for effective spraying. The restricted nozzle has an array of internal flow-interrupting baffles that further promote mixing by generating turbulence, condense the stream, and shape the spray pattern.

An admixing system for fire-extinguishing installations is provided for generating a mixture (premix) of extinguishing medium and extinguishing medium additive by admixing an extinguishing medium additive to an extinguishing medium. The admixing system has a motor that can be driven by a flow of extinguishing medium, an admixing pump that is connected to the motor and serves for supplying the extinguishing medium additive to an extinguishing medium additive inlet line, an admixing line, and an extinguishing medium additive outlet line from which the extinguishing medium additive is admixed to the extinguishing medium in the admixing line. The admixing pump is a piston pump having multiple cylinders and at least two outputs connected to the cylinders. At least one first output, through which return flow is possible, can be switchably fluidically connected either to a return flow line through which the extinguishing medium additive flows back to the admixing pump, or to the extinguishing medium additive outlet line. If the extinguishing medium additive flows from the return-flow-compatible output back to the admixing pump, it is therefore not admixed to the extinguishing medium in the admixing line.

Cartridge for extinguishing-agent additive

The cartridge is used for arranging in a liquid extinguishing agent in a fire extinguisher in which the extinguishing agent can be acted upon for use with a pressure gas. The cartridge has a receiving space for an extinguishing-agent additive which has an outlet opening with a closure element opening automatically under positive pressure at one end. During the pressurising, good mixing of the extinguishing-agent additive with the fire extinguishing agent is to be ensured, in which case the cartridge is also to be reusable. Therefore, at least one cartridge section is designed as a cylinder with a piston which is displaceable in the cylinder and closes a pressure inlet end of the cylinder to the outside. A cartridge part of reduced cross-section adjoins said cylinder section. Located at the end of said cartridge part remote from the cylinder is the outlet opening with the closure element, the outer pressure-absorbing area of which is smaller than the outer pressure-absorbing area of the piston.

The gear flow meter elements are driven only by the force of liquid pumped by the enmeshed gears of the gear pump and cause very low pressure drop across the flow meter elements. Therefore, inaccurate measurements of flow rates due to slippage and viscosity variation are reduced compared to measuring the rotary speed of gear pump gears directly. The system is optimally used to meter and add foam chemical into a pressurized water line for fighting fires.

A method of forming an effervescent fine liquid mist includes mixing liquid and chemical reactant to form non-toxic, noncombustible gas bubbles; mixing the liquid and the gas bubbles to form a two-phase fluid flow; and directing the two-phase fluid flow through at least one convergent/divergent nozzle.

本发明涉及消防灭火技术领域，具体地说是一种中低倍复合型消防泡沫炮。一种中低倍复合型消防泡沫炮，包括底座、蜗轮箱、控制装置，其特征在于：底座的上方采用法兰连接水平蜗轮箱的一端，水平蜗轮箱的另一端采用法兰连接中弯管的一端，中弯管的另一端连接仰俯蜗轮箱的一端，仰俯蜗轮箱的另一端采用上弯管连接复合泡沫喷射装置，所述的中弯管的一侧采用软管连接复合泡沫喷射装置。同现有技术相比，提供一种中低倍复合型消防泡沫炮，在中低倍消防炮的复合泡沫喷射装置上进行结构的改进，使其既保持原有低倍泡沫炮得的性能，而且还能将较高发泡率的中倍泡沫带到远距离射程中。
