Abstract

The invention discloses an abrasive water cutting and fire extinguishing device which is applicable to the technical field of fire fighting instruments, and particularly relates to a device for cutting and foam fire extinguishing by utilizing a premixed abrasive jet technology. The abrasive water cutting and fire extinguishing device comprises a water tank and a foam liquid tank, wherein an exchange valve is arranged between the water tank and the foam liquid tank, and is connected with a high pressure pump; a high pressure pump pipeline is provided with a pressure meter, a safety valve and a pressure regulating valve; the high pressure pump is connected with an abrasive tank through a pipeline; the abrasive tank is respectively connected with a cutting sprayer and a foaming sprayer through stop valves; a unidirectional valve is arranged between the high pressure pump and the abrasive tank; an abrasive stop valve and an abrasive mixing cavity are arranged below the abrasive tank. According to the invention, the device has double functions of cutting and fire extinguishing; water in the water tank is mixed with abrasive materials through the high pressure pump and the abrasive tank, and is sprayed out from the cutting sprayer so as to cut; a foam liquid is sprayed out from the foaming sprayer through the high pressure pump so as to form large continuous foam to extinguish fire. The device provided by the invention is convenient to cut, extinguish fire and exchange, is high in cutting capability, is obvious in fire extinguish effect, and is low in water using quantity.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to a front-mixing abrasive water jet cutting and foam fire extinguishing device. Background technique [0002] Demolition is one of the main means of fire fighting and rescue. At the scene of a fire, firefighters often have to achieve rescue by means of demolition. If the means of demolition is inappropriate, flammable and explosive materials in a relatively sealed space A secondary explosion occurred, posing a serious threat to the safety of personnel. At present, the rescue tools equipped by firefighting forces at home and abroad are mainly divided into manual, electric, pneumatic, hydraulic and chemical power types. These rescue tools are labor-intensive and cost-intensive. The time is long, the process is complicated, the demolition efficiency is low, and there are certain safety hazards. It is difficult to extinguish fire in places with unknown fire conditions....
