Abstract
The utility model discloses a split storage type liquid fire extinguisher, which comprises: the fire extinguishing agent storage bag is arranged in the cylinder and is in sealing connection with the valve assembly, and the fire extinguishing agent storage bag is filled with liquid fire extinguishing agent; and the rest cavity parts in the cylinder body are filled with pressurized gas. The utility model has the advantages of long storage time, easy injection, avoidance of repeated filling of pressurized gas, avoidance of pressure relief and the like.
Description
Technical Field
The utility model relates to the field of fire fighting, in particular to a split storage type liquid fire extinguisher.
Background
At present, traditional plain type fire extinguisher adopts the integrative mode of storing of fire extinguishing agent and pressurized gas, also, and the barrel is inside to be integral cavity, and liquid fire extinguishing agent is placed to the cavity lower part, and cavity upper portion (the top of liquid fire extinguishing agent) fills the pressurized gas, and when using, through stretching into the siphon in the cavity, erupts liquid fire extinguishing agent and pressurized gas in the lump. However, in this storage mode, since the fire extinguishing agent is in contact with the cylinder for a long time, the fire extinguishing agent slowly corrodes the cylinder over time, the pressure stored in the cylinder is reduced with the increase of the storage time, and the problem of pressure relief exists; at the same time, the reduction in the stored pressure also results in the extinguishing agent not being sprayed out. In addition, the mode that fire extinguishing agent and pressurized gas are integrative to be stored makes when putting out a fire, can only the barrel upwards spray, can not the rotatory injection of arbitrary angle, has influenced fire control effect to a certain extent.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems, the utility model provides the split storage type liquid fire extinguisher which has long storage time, avoids barrel corrosion, avoids repeated charging of pressurized gas and avoids the problem that fire extinguishing agents cannot be sprayed due to pressure relief caused by long-time storage.
The purpose of the utility model is realized by the following technical scheme:
a split-storage liquid fire extinguisher comprising: barrel, valve member, liquid fire extinguishing agent, pressurized gas, liquid fire extinguisher still includes:
the fire extinguishing agent storage bag is arranged in the cylinder and is in sealing connection with the valve assembly, and the fire extinguishing agent storage bag is filled with liquid fire extinguishing agent; the interior of the cylinder body is a cavity, and except the space occupied by the fire extinguishing agent storage bag, other cavity parts are filled with pressurized gas.
The barrel includes stack shell, head and disk seat, and the barrel is cylindric structure, is sealed state after the use, guarantees that pressurized gas can not reveal. The cylinder body, the end socket and the valve seat can be assembled together through a welding process or can be directly formed through stretching.
The valve component comprises a valve body, a nozzle and a pressing handle, wherein the valve body is in threaded sealing connection with a valve seat in the cylinder body. Preferably, the valve assembly further comprises a safety catch, and the safety catch needs to be pulled out before the fire extinguisher is used. More preferably, the valve body and the valve seat in the cylinder are in sealing connection through a thread fit sealing ring, and sealing performance is guaranteed.
The fire extinguishing agent storage bag can resist the corrosion of a liquid fire extinguishing agent, and the compressive strength is not less than 1.2 Mpa. Preferably, the fire extinguishing agent storage bag is an aluminum bag, and the aluminum bag can withstand the inner wall corrosion test required by national standard specifications without cracking after being checked, and the sealing performance and the compressive strength of the aluminum bag meet the requirements.
The liquid fire extinguishing agent is perfluorohexanone, and does not cause secondary pollution after being sprayed.
The pressurized gas is nitrogen or compressed air, and the pressure is 0.8-1.0 MPa.
When the split storage type liquid fire extinguisher is used, the pressing handle on the valve component is pressed down, the pressurized gas stored in the cylinder body can extrude the liquid fire extinguishing agent in the fire extinguishing agent storage bag, and the fire extinguishing agent is completely sprayed out from the nozzle on the valve component without fire extinguishing agent residue. Meanwhile, the pressurized gas in the cylinder body is not released, the pressurized gas can be stored in the cylinder body for a long time, repeated filling is avoided, and the fire extinguisher can be continuously used by filling the fire extinguishing agent into the storage bag again according to requirements after fire extinguishment.
Compared with the prior art, the technical scheme of the utility model has the beneficial effects that:
1. in the split storage type liquid fire extinguisher, the liquid fire extinguishing agent is separated from the cylinder body and is not contacted with the cylinder body, so that the corrosion to the cylinder body is avoided, the storage life is prolonged, and the problem that the fire extinguishing agent cannot be sprayed due to pressure relief in long-time storage is solved.
2. The split storage type liquid fire extinguisher still is in a sealed state after being used, pressurized gas is not sprayed out, and repeated filling of the pressurized gas is avoided.
3. The split storage type liquid fire extinguisher adopts the perfluorohexanone as the liquid fire extinguishing agent, is safe and environment-friendly, and has no secondary pollution.
Drawings
FIG. 1 is a schematic view showing a constitution of a separate storage type liquid fire extinguisher according to embodiment 1 of the present invention.
Detailed Description
The present invention is further illustrated by the following examples, which are not intended to limit the utility model to these embodiments. It will be appreciated by those skilled in the art that the present invention encompasses all alternatives, modifications and equivalents as may be included within the scope of the claims.
Example 1
Fig. 1 is a schematic view showing a structure of a separate storage type liquid fire extinguisher, as shown in fig. 1, comprising:
the valve component 1 comprises a valve body, a nozzle, a pressing handle and a safety buckle, and the valve component and the connection relation thereof are the prior art and are not described in detail herein. The valve body is in sealing connection with the valve seat in the cylinder body by threads and matching with a sealing ring;
and the fire extinguishing agent storage bag 6 is an aluminum bag and is arranged in the cylinder body and is in sealing connection with the valve component, perfluorohexanone is filled in the aluminum bag to serve as the liquid fire extinguishing agent 5, and the rest cavities except the aluminum bag in the cylinder body are filled with nitrogen to serve as pressurized gas.
When the fire extinguisher is used, the safety buckle is firstly pulled out, the pressing handle is pressed, the nitrogen extrudes the perfluorohexanone fire extinguishing agent in the aluminum bag, the perfluorohexanone fire extinguishing agent is completely sprayed out from the nozzle, the nitrogen is still stored in the cylinder and is not released, repeated filling is not needed after the fire extinguisher is used, and only the perfluorohexanone fire extinguishing agent is filled.
Example 2
This embodiment provides a liquid fire extinguisher of split type storage formula, and the difference with embodiment 1 lies in: the embodiment is not provided with a safety buckle, and the fire extinguisher cover is removed during use, and the fire extinguishing agent can be sprayed out to extinguish fire by directly pressing the valve starting device.
