Description
Technical field
The utility model relates to a kind of gas type dry powder extinguishing installation.
Background technology
Powder extinguishing system is as one of four traditional large fire extinguishing systems (water, gas, foam, dry powder) at present, be widely used, along with the application of dry-chemical fire extinguishing technology reaches its maturity, powder extinguishing system has had larger development, except traditional gas bomb type and storage die mould powder extinguishing system equipment, China has also developed gas driven type powder extinguishing system product, and product structure is simple, easy to install and use, have the irreplaceable advantage of traditional powder extinguishing system.For allow dry powder extinguishing installation can be in explosive gas atmosphere Secure Application, follow GB " explosive atmosphere 3836-2010〉requirement, China has developed explosion-proof type combustion gas dry powder extinguishing installation.This device is in petrochemical industry, and the industries such as colliery are widely used.Common explosion-proof type combustion gas dry powder extinguishing installation has following deficiency at technological processing for explosion protection feature and Structural Tectonics at present:
1, present explosion-proof type extinguishing device on the market only is that the outlet wire in the gas generator is divided, and has done technological processing for explosion protection feature, and security is not high.
2, the encapsulation process between each connector is not in place, and sealing is not strong.The meal outlet sealing plate only depends on locknut and tank body locking, and security performance can not be guaranteed in adverse circumstances or explosive atmosphere.
3, the design of the meal outlet of dry powder is unfavorable for that dry powder sprays, and affects extinguishing property.
Summary of the invention
For solving above technical deficiency, it is a kind of safe that the utility model provides, the gas type dry powder extinguishing installation of good extinguishing effect.
The utility model is realized by following measures:
A kind of gas type dry powder extinguishing installation of the present utility model comprises tank body, and nut is passed through at the tank body top
Locking has the gas generator that stretches in the tank body, described tank body lower end arranges nozzle, be provided with meal outlet in the nozzle, described tank body top and gas generator locking place overcoat have explosion stack, described explosion stack lower end is welded on the tank body, the explosion stack screw top is connected with block, and the sidewall of described explosion stack has passed line pipe joint and has been provided with fluid sealant at the place of passing.
Above-mentioned meal outlet comprises upper circular cone cavity wide at the top and narrow at the bottom and up-narrow and down-wide lower circular cone cavity, and the upper port of described upper circular cone cavity is communicated with tank body, and the upper port of the lower port of upper circular cone cavity and lower circular cone cavity connects.
The lower port of said nozzle is provided with lock nut, and the lower port place shutoff of the lower circular cone cavity of described meal outlet has sealing plate and is provided with double-deck sealing ring.
The beneficial effects of the utility model are: 1, the design of explosion stack has increased the explosion-proof of extinguishing device, has improved the security in adverse circumstances and explosive atmosphere.2, meal outlet can strengthen the impulsive force of primary mixture, opens sealing plate in the short time fully at the utmost point.And after sealing plate is opened, primary mixture is led, forming the fan-shaped spray effect, powder mixture forms the best spray pattern of fire extinguishing effect in injection.This design has namely increased fire-fighting area, has improved again extinguishing property.3, adopt the double-layer seal rings design between dry powder outlet and the sealing plate, and with lock nut locking, improved sealing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top structure schematic diagram of the present utility model.
Fig. 3 is polycrystalline substance schematic diagram of the present utility model.
Wherein: 1 tank body, 2 gas generators, 3 line pipe joints, 4 explosion stacks, 5 blocks, 6 nozzles, circular cone cavity on 7,8 times circular cone cavitys, 9 lock nuts, 10 sealing plates, 11 sealing rings.
The specific embodiment
As shown in Figure 1, a kind of gas type dry powder extinguishing installation of the present utility model comprises tank body 1, tank
As shown in Figure 2, tank body 1 top and gas generator 2 locking place overcoats have explosion stack 4, and explosion stack 4 lower ends are welded on the tank body 1, and explosion stack 4 screw top are connected with block 5, and the sidewall of explosion stack 4 has passed line pipe joint 3 and has been provided with fluid sealant at the place of passing.Increase the explosion-proof of extinguishing device, improved the security in adverse circumstances and explosive atmosphere.
As shown in Figure 3, meal outlet comprises upper circular cone cavity 7 wide at the top and narrow at the bottom and up-narrow and down-wide lower circular cone cavity 8, and the upper port of upper circular cone cavity 7 is communicated with tank body 1, and the upper port of the lower port of upper circular cone cavity 7 and lower circular cone cavity 8 connects.Upper circular cone cavity 7 more enough dry powder acceleration ejections that make in the tank body 1 of meal outlet, the impulsive force of enhancing primary mixture is opened sealing plate 10 fully at the utmost point in the short time.After sealing plate 10 was opened, 8 pairs of primary mixtures of lower circular cone cavity led, and formed the fan-shaped spray effect, and powder mixture forms the best spray pattern of fire extinguishing effect in injection.Namely increase fire-fighting area, improved again extinguishing property.The lower port of nozzle 6 is provided with lock nut 9, and with lock nut 9 lockings, the lower port place shutoff of the lower circular cone cavity 8 of meal outlet has sealing plate 10 and is provided with double-deck sealing ring 11.Improved sealing.
The above only is the preferred embodiment of this patent; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
