Description

Gas fire extinguishing system sprays state warning device

Technical Field

The utility model belongs to the technical field of the fire-fighting equipment and specifically relates to a gaseous fire extinguishing systems sprays state warning device is related to.

Background

The gas fire extinguishing system is widely applied to fire extinguishing in a closed environment, and carbon dioxide (other fire extinguishing gases such as heptafluoropropane) sprayed by the gas fire extinguishing system has an inhibiting effect on a fire source. In the existing gas fire extinguishing system, the starting of carbon dioxide depends on an automatic fire alarm and linkage system. When a fire disaster occurs, the automatic fire alarm and linkage system drives the audible and visual alarm, the electric horn alarm, the alarm whistle, the rotary lamp and other devices to alarm, so as to prompt people to evacuate, and the linkage valve in the area where the fire is on is opened to extinguish the fire (the linkage valve is opened for 0-30 seconds in a delayed manner, so that people can evacuate conveniently).

Due to the reliability of components and linkage systems, after a fire occurs, the automatic fire alarm and linkage system cannot necessarily open the linkage valve. Because of the closed environment, whether the linkage valve is opened or not, whether the carbon dioxide gas in the storage tank is used up or not and whether the carbon dioxide gas is sprayed out or not are judged, and people who put out a fire in the future cannot know the carbon dioxide gas. If the fire goes into inspection or the linkage valve is opened, the fire extinguishing personnel can be suffocated; if the fire is not put into the fire extinguisher, the fire extinguishing time can be missed, and great property loss is caused.

In addition, in the maintenance and repair processes of the system, the linkage valve is opened accidentally due to equipment failure or manual misoperation, and at the moment, the fire alarm system cannot give out sound alarm or light alarm, so that danger is brought to workers in a sealed area.

Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms "front", "back", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate directions or positional relationships based on those shown in the drawings, which are merely for convenience of description, but do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Example 1:

the utility model provides a gaseous fire extinguishing systems sprays state warning device, as shown in figure 1, includes gas holder 1, and gas holder 1 is connected with one set of injection unit 11, injection unit 11 includes a linkage valve 2 and a jet-propelled pipe 3, is connected with manifold 4 on jet-propelled pipe 3, and the pipe diameter of manifold 4 is less than the pipe diameter of jet-propelled pipe 3, is provided with pneumatic loudspeaker 5 in the gas outlet of manifold 4. When the linkage valve 2 is opened, most of carbon dioxide gas is sprayed out of the gas spraying pipe 3, and a small amount of carbon dioxide gas is sprayed out of the manifold 4, so that the pneumatic horn 5 gives out sound and gives an alarm.

When the fire-extinguishing personnel hear the pneumatic horn 5 to give an alarm, the linkage valve 2 is proved to be in an open state, and the gas fire-extinguishing system is in a spraying state. In order not to hinder the pneumatic horn 5 from sounding, the pneumatic horn 5 is arranged outside the device and close to the linkage valve 2, so that the propagation of sound waves is facilitated.

Example 2:

different from the embodiment 1, as shown in fig. 2, two sets of injection units 11 are connected to the air storage tank 1 of the warning device, and each set of injection unit 11 includes a linkage valve 2, an air injection pipe 3 and a manifold 4. And the two manifolds 4 are respectively provided with a one-way valve 6 and a pressure reducing valve 7, wherein the one-way valve 6 is communicated from the air inlet to the air outlet of the manifold 4 in a one-way, and the pressure reducing valve 7 is positioned between the one-way valve 6 and the pneumatic sound alarm. The air outlets of the two manifolds 4 are communicated with each other through a connecting pipe, and the connecting pipe is connected with a pneumatic horn 5.

The two sets of injection units 11 share one pneumatic horn 5, when the linkage valve 2 in one set of injection unit 11 is in a problem and cannot be opened, the linkage valve 2 in the other set of injection unit 11 is opened, and then the pneumatic horn 5 can still give an alarm. The function of the one-way valve 6 is to prevent carbon dioxide gas from escaping from the other manifold 4, reducing the pressure and the alarm sound level of the pneumatic horn 5. The pressure reducing valve 7 is used for adjusting air pressure and can change the alarm tone of the pneumatic loudspeaker 5.

In the two embodiments, the pneumatic horn 5 gives out an alarm sound, fire extinguishers can know that the linkage valve 2 is in an open state, but after the carbon dioxide gas in the gas storage tank 1 is released, the pneumatic horn 5 cannot give an alarm even if the linkage valve 2 is opened. Meanwhile, people who come to extinguish a fire enter the closed space to inspect or open the linkage valve 2, and suffocation danger is brought to the fire extinguishing personnel. Therefore, there is a continuing need for improved solutions.

Example 3:

as shown in fig. 3, a set of injection units 11 is connected to an air storage tank 1 of the warning device, and each injection unit 11 comprises a linkage valve 2, an air injection pipe 3 and a manifold 4. The manifold 4 is provided with a one-way valve 6 and a pressure reducing valve 7, the manifold 4 between the one-way valve 6 and the pressure reducing valve 7 is provided with a pressure switch 8, and the pressure switch 8 is connected with an electric horn 9 alarm circuit. Due to the existence of the one-way valve 6 and the pressure reducing valve 7, even if the carbon dioxide gas in the gas storage tank 1 is completely released, the gas pressure still exists in the manifold 4 between the one-way valve 6 and the pressure reducing valve 7, the pressure switch 8 can be closed by the gas pressure, the alarm circuit of the electric horn 9 is conducted, and the electric horn 9 gives an alarm.

The pneumatic horn 5 and the electric horn 9 give an alarm after the linkage valve 2 is opened, but the pneumatic horn 5 stops giving an alarm after the carbon dioxide gas in the gas storage tank 1 is released, and the electric horn 9 gives an alarm all the time. Then, if the tone of the pneumatic horn 5 is distinguished from the tone of the electric horn 9, different information can be provided to the fire fighter. If the pneumatic horn 5 and the electric horn 9 alarm at the same time, the linkage valve 2 is proved to be in an open state, and the gas fire extinguishing system is in a spraying state. If only the electric horn 9 gives an alarm, the linkage valve 2 is proved to be opened, the carbon dioxide gas in the gas storage tank 1 is exhausted, and fire extinguishing personnel cannot enter the fire extinguishing apparatus.

A manual air release valve 10 is arranged between the check valve 6 and the pressure reducing valve 7. After fire extinguishing, the electric horn 9 is required to stop alarming. At this time, the pressure between the check valve 6 and the pressure reducing valve 7 is released by the manual air release valve 10, so that the pressure switch 8 is turned off, and the electric horn 9 stops alarming.

The part of the utility model not detailed is prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
