Fire-fighting equipment with automatic opening function

Abstract

The utility model relates to a fire-fighting device with an automatic opening function. The fire-fighting device comprises a pneumatic valve element, a piston device and a gas supply valve group, wherein the gas supply valve group outputs a gas to the piston device through the pneumatic valve element to control the action of the ejection rod the piston device, and the pneumatic valve element further comprises a valve element main body, a temperature sensing module, a movable valve element, a fixed cover and a pricking pin assembly; when the temperature sensing module senses an abnormal temperature, the movable valve element and the pricking pin assembly are pushed, the sealing sheet of a gas steel cylinder is pricked, and compressed gas penetrates through the pricking pin assembly to the piston device, thus the ejection rod of the piston device is pushed outwards, and a window is automatically opened.

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
