A fire-fighting device with automatic opening function

Abstract

The invention discloses a puncture valve for controlling actions of an air cylinder. The air cylinder comprises an ejection rod and a piston and is provided with a first air port communicated to the front portion of the piston and a second air port communicated to the rear portion of the piston. The puncture valve comprises a valve body, a valve core, a fixing frame, a puncture needle, air bottle and other parts. The puncture valve controls actions of the valve core through a sensing alcohol bottle, accordingly a first air inlet and a second air inlet of the puncture valve are in different match with a first working port, a second working port and an air releasing port of the puncture valve, the ejection rod of the air cylinder can eject a door window and accordingly is reliable. After optimization, even if the temperature cannot reach the breaking condition of the sensing alcohol bottle, the electric ejection rod of the puncture valve can also enable the sensing alcohol bottle to break and then control the actions of the valve core, and accordingly the working reliability of the puncture valve is further improved.

Description

technical field [0001] The invention relates to the technical field of safety equipment, in particular to a fire-fighting equipment which has a valve part capable of piercing a steel cylinder and can be opened automatically. Background technique [0002] The so-called fire refers to the burning of fire against the will of ordinary people, or the phenomenon of expanding burning due to improper and specific purposes. Fires can be divided into four categories according to different burning substances, including ordinary combustibles, combustible liquids, electrical equipment and active metals. Among them, ordinary combustibles such as wood products, paper fibers, cotton, cloth, synthetic resins, rubber, plastics etc.; combustible liquids such as petroleum, flammable gases such as ethane gas, acetylene gas, flammable grease such as paint, etc.; electrical equipment involved in electrification, such as electrical appliances, transformers, wires, switchboards, etc.; active metals ...

AI Technical Summary

Problems solved by technology

However, when a fire breaks out, time is very tight, and when every second counts, it is difficult for personnel to spare time to open windows, especially in large buildings, such as exhibition halls or factories, where the windows are often located beyond the reach of personnel. Not to mention opening, therefore, in case of fire, how to automatically open windows in time has become an important research direction for fire-fighting equipment
