Connecting pipe for novel fire-fighting equipment

Abstract

The invention discloses a connecting pipe for novel fire-fighting equipment, and belongs to the field of fire-fighting equipment. The connecting pipe is a metal straight pipe and is characterized in that one end of the connecting pipe is provided with external threads and is connected with an ejector to form an inlet, the other end of the connecting pipe is provided with inner threads and is connected with a nozzle or a spraying hose to form an injection opening, moreover, the diameter of a main body part of the connecting pipe is the same as the diameter of the inlet, and the part between theinjection opening and the main body part is in a conical surface to be shrunk; a plurality of planes are evenly pressed on the outer wall of the main body part of the connecting pipe along the circumference, so that the positions, corresponding to the planes of the outer wall, of the inner wall of the main body part protrudes, and concave-convex surfaces which are uniformly staggered along the circumference are formed on the inner wall of the main body part; and a row of annular reinforcing ribs are arranged in the middle of the outer wall of the connecting pipe. According to the connecting pipe for the novel fire-fighting equipment, the defects of existing foam fire extinguishing equipment are overcome, and the effect of being rapidly foamed is achieved, so that the connecting pipe has the characteristics that a pipe body is short, foaming is fast, the cost is saved, continuous foaming can be achieved without a foaming barrel, safety and durability are achieved and the service life is long.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, and more specifically, relates to a novel connecting pipe for fire-fighting equipment. Background technique [0002] In daily life, the occurrence of fire is ubiquitous, which brings a lot of troubles to people's life. There are many reasons for the occurrence of fire, and many of the occurrence of fire are caused by subjective factors except objective reasons. At present, my country's fire-fighting facilities are also constantly developing. There are many fire-fighting equipment on the ground, in transportation and on the sea. The common types are: fire extinguishers, fire extinguishing boxes, foam liquid, fire water guns, indoor fire hydrants and fire hydrants. box etc. [0003] Foam fire extinguishing equipment is an important part of the foam fire extinguishing system. According to the installation and use of equipment, it can be divided into fixed, semi-fixed and mobile foam fire extin...

AI Technical Summary

Problems solved by technology

The foam injection method of the fixed foam fire extinguishing system can be sprayed above the liquid or under the liquid. The disadvantage is that when the oil tank explodes, the foam mixture pipe and the foam generator are easily damaged, causing the fire to be out of control; the mobile foam fire extinguishing system The system is flexible in use and not affected by the initial combustion and explosion. However, because it is applied after a fire occurs, the fire fighting is not as timely as the fixed foam fire extinguishing system. At the same time, the fire extinguishing equipment
