Escape system

Abstract

The invention provides an escape system. The escape system comprises a gas bottle, a bottle valve pressure reducer, a gas supply pipeline and a head cover; an exhalation valve is arranged on the headcover; the gas bottle and the gas supply pipeline are connected with the bottle valve pressure reducer; the gas supply pipeline is connected with the head cover through a fast-connection connector; and the gas supply time of the escape system is no less than 10 min, and the gas supply flow of the gas bottle is 17.3 L / min. According to the escape system, compared with escape systems in the currentmarket, the size and weight are smaller, the gas supply time is sufficient, the using efficiency is improved greatly, and it is efficiently guaranteed that a user escapes an accident site safely.

Description

technical field [0001] The invention relates to a civilian escape system, in particular to an escape system for assisting breathing. Background technique [0002] In recent years, with the development of the economy, the level of urbanization in my country has been continuously improved, and the contradiction between the increase of urban population and the insufficient supply of urban construction land has become prominent. In order to alleviate this contradiction, people's living places tend to be high-rise. In addition, the living conditions of the people are constantly improving. House interiors, furniture items and furnishings are constantly being enriched. The improvement of living conditions has greatly improved the living comfort of the people, but at the same time there are fire safety hazards. The main reasons are: 1) House interiors, furniture and furnishings are mostly combustible materials such as wood, plastic and fabric. When a fire occurs, these materials ...

Problems solved by technology

However, different types of filter tanks filter different components of toxic gases.

However, indoor decoration and furnishings include combustible materials such as wood, plastic, textiles and fibers. The combustion of these materials will produce various harmful gases. Currently, the filter escape systems on the market can only filter certain toxic gases in different models. Neither can filter all toxic and harmful gases, and the filtering effect is not satisfactory. Even if it can assist escape, it still has certain damage to the human body.

In addition, when the user puts on the hood, the gas volume in the hood decreases when inhaling, and the hood is under negative pressure, so that the neck seal of the hood cannot be 100% sealed, and the surrounding harmful gas can flow from the neck without passing through the filter tank. The seal enters the hood, thereby endangering the life safety of the user

[0006] The current air-supply escape system has its own air supply source, and the hood is under positive pressure during work, which can overcome the risk of toxic gas endangering the safety of users. However, most of the existing air-supply escape systems use 2.2L, The aluminum alloy gas cylinder with a working pressure of 20MPa is large in size and heavy in weight, which does not better meet the performance of users

If the nominal volume of the gas cylinder is simply reduced, the gas supply time will be sacrificed, which will seriously threaten the personal safety of the user.
