Pneumatic windows with multiple opening functions

Abstract

The invention discloses a pneumatic window with multiple opening functions, comprising: a window sash; a cylinder having a first air inlet, a second air inlet and a cylinder push rod; a first fire detector connected to the first air inlet tube; the second fire detection tube, the second fire detection tube is connected to the first fire detection tube; the first air pipe communicating with the second air inlet; the electromagnetic valve with the air intake end and the first air outlet end and the second air outlet end, the first The fire detection tube is connected to the first gas outlet, and the first gas pipe is connected to the second gas outlet; the gas storage tank is connected to the second gas pipe, and the second gas pipe is connected to the intake end; the first fire detection tube passes through The valve of the first fire detection tube is communicated with a fourth air pipe, and the fourth air pipe is communicated with the second air pipe; the first air pipe is communicated with a fifth air pipe through a first air pipe valve, and the fifth air pipe is communicated with the second air pipe; A third air pipe is connected between the fire detection tube and the second air pipe. The invention has the advantages of various opening modes, relatively reliable, better stability and airtightness.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to an aerodynamic window with multiple opening functions. Background technique [0002] With the rapid development of the economy, various large-scale buildings have sprung up, such as trade cities, airports, railway stations, gymnasiums, logistics centers, etc. While these buildings meet the material and cultural needs of the people, they also bring a lot of hidden dangers to fire safety. The hazards of smoke in fires must be paid attention to, and then the reliability of natural smoke exhaust equipment is even more important. [0003] For this reason, some window opening technologies with multiple opening functions have occurred, mainly adding mechanisms such as wire ropes and pulleys on the basis of electric window opening machines to realize multiple opening functions. [0004] However, these technologies are difficult to realize for the complex internal structu...

AI Technical Summary

Problems solved by technology

[0004] However, these technologies are difficult to realize when the internal structure of the building is complex, and the temperature measurement points where the thermal fusion is turned on are also discontinuous, so the reliability is insufficient

Moreover, the hot-melt opening temperature measurement points of some pneumatic window opening machines are even more isolated

At the same time, if the air path of the pneumatic system is made of plastic materials, it may be bitten by mice, causing the system to fail due to lack of air; if it is a metal pipe, it is difficult to achieve scientific temperature measurement

In addition, any gas path may leak

If the control system is always in the closed state, it is difficult to open manually; if it is in the stopped state, the air cylinder pressure of the control window action will continue to drop due to air leakage, or the window sash will open accidentally, which is not conducive to windproof, rainproof and air conditioning. , or in an emergency, the manual cannot be opened due to insufficient air pressure

More importantly, the above-mentioned pneumatic opening window is opened in the state of no electricity by using a backup power supply. Once the power line fails, it will inevitably not be able to open smoothly.
