Abstract
The utility model relates to a fire extinguisher, particularly a fire extinguisher in which a gas cylinder is arranged. The utility model belongs to the technical field of fire fighting equipment. The utility model mainly comprises an outer shell, a spray head assembly, a gas release valve, a vent pipe and dry powder, wherein the air release valve is arranged on the spray head assembly, and is provided with a bumper and an unloading safety ring; the vent pipe and the dry powder are arranged in the outer shell. The utility model is characterized in that the gas cylinder in which high pressure flame retardancy gas is arranged in the outer shell; the gas cylinder is arranged on a gas cylinder bracket which is in screw connection with the spray head assembly; a thimble which passes through the spray head assembly and is connected with the gas release valve is arranged above the middle part of a gas cylinder cap of the gas cylinder; as gas is sealed in the gas cylinder, the gas and the dry powder are separated in the fire extinguisher. Thus, the gas and the dry powder can be stored for a long term, and have no leakage. Pressure in the outer shell is zero when the fire extinguisher is stored. Thus, storage safety and using reliability are ensured. The utility model is convenient for the bulk filling of the dry powder and the routine maintenance of the fire extinguisher, and effectively raises production efficiency and maintenance efficiency.
Description
One, technical field
The utility model relates to a kind of fire extinguisher, establishes the fire extinguisher of gas cylinder in especially a kind of, belongs to the fire-fighting equipment technical field.
Two, background technology
Existing fire extinguisher all is that gases at high pressure and dry powder blend are filled in steel cylinder, all the time be in high pressure conditions in the steel cylinder, deposit very dangerous, and because long-term pressurized, the sealing property of valve is not good enough, the fire-retardant gas of high pressure in the long term storage steel cylinder slowly leaks easily, cause steel cylinder internal pressure deficiency, thereby influenced the reliability of using, in order to guarantee that serviceability needs regularly to replenish the fire-retardant gas of high pressure in steel cylinder, owing to be high pressure conditions in the steel cylinder, brought inconvenience for the can of dry powder and the detection maintenance of fire extinguisher simultaneously.
Three, the content of utility model
The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of security performance height is provided, uses gas cartridge fire extinguisher reliable, easy access.
For achieving the above object, the utility model is achieved in that a kind of gas cartridge fire extinguisher, comprise shell, be connected in the shower nozzle assembly at shell aperture place and dress being provided with bumper bar and unloading the vent valve of relieving ring and place breather pipe and dry powder in the shell thereon by swivel nut, its special character is, the gas cylinder of the fire-retardant gas of dress high pressure in being provided with in the enclosure, gas cylinder is installed on the gas cylinder carriage that is threaded with the shower nozzle assembly, is provided with a thimble that passes the shower nozzle assembly, is connected with vent valve above the middle part of the bottle cap of gas cylinder.
The bottle cap of above-mentioned gas cylinder and the bottleneck of gas cylinder are that diaphragm welding is fixedly connected, and the middle part of bottle cap is provided with thin layer, so that thimble punctures.
Compared with the prior art the utility model is stored in the gas cylinder owing to the fire-retardant gas of high pressure on the one hand, and gas cylinder adopts the diaphragm solder up, but the gas long term storage does not have leakage, has guaranteed the reliability of using; Internal pressure owing to fire extinguisher big steel cylinder during long-term storage is zero on the other hand, thereby has guaranteed the security between storage period; Moreover, be convenient to the bulk filling of dry powder owing to dry powder and gas packing, also made things convenient for the detection maintenance of fire extinguisher simultaneously, the production efficiency of manufacturer and maintenance personal's overhaul efficiency have been improved effectively, and can make the fire extinguisher of plurality of specifications as required, reasonable in design, dependable performance.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of gas cylinder.
Five, the specific embodiment
For understanding the utility model better, it is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1, Fig. 2 as seen, gas cartridge fire extinguisher described in the utility model mainly is by shell 1, be connected in the shower nozzle assembly 7 at shell aperture place and dress being provided with bumper bar 9 and unloading the vent valve 11 of relieving ring 10 and place breather pipe 3 in the shell thereon by swivel nut 8, dry powder 2 and gas cylinder 5 constitute,: the fire-retardant gas of high pressure is housed in the gas cylinder 5, gas cylinder 5 is installed on the gas cylinder carriage 4 that is threaded with shower nozzle assembly 7, the bottle cap 12 of gas cylinder 5 is fixedly connected with the diaphragm welding with the bottleneck of gas cylinder, and the middle part of bottle cap 12 is provided with thin layer 13, passes shower nozzle assembly 7 above thin layer 13, the thimble 6 that is connected with vent valve 11.
During use, open and unload relieving ring, push vent valve, the thimble that is attached thereto punctures the thin layer that gas cylinder seals, the fire-retardant gas of high pressure in the gas cylinder is entered rapidly in the shell of fire extinguisher, dry powder in the fire extinguisher reaches the purpose of fire extinguishing from the shower nozzle ejection under the effect of gases at high pressure, easy to use, safe and reliable.
