Problems solved by technology

When using it, firstly it takes time to take the fire extinguisher and turn it on, and secondly, because the bottle head valve is on the top, when it is opened, due to the effect of gravity, the speed of spraying dry powder from the fire extinguisher is relatively slow
In addition, traditional fire extinguishers need to be returned to the factory for filling with dry powder and pressurized gas, and the maintenance cost is high
Moreover, in the state of movement such as on-board, the dry powder fire extinguisher is easy to vibrate, and the puncture needle compresses the limit spring to puncture the diaphragm by mistake, thereby releasing the fire extinguishing gas by mistake when it is not required for fire extinguishing

Embodiment Construction

[0020] refer to figure 1 , is a kind of dry powder fire extinguishing device of the present invention. Among them, the fire extinguishing device includes a filling valve 3, the lower part of the filling valve is connected to the powder bottle 2 by welding, and the lower part of the powder bottle is threadedly connected to the bottle head valve 1. When the fire extinguishing device is used, this inverted structure can respond quickly and achieve faster spray effect. Powder bottle 2 side walls are connected with rubber plate 4, and rubber plate outside is connected with support 5, can install fire extinguishing device by support 5, and rubber plate 4 has elasticity, can reduce the relative vibration between powder bottle and support.

[0021] refer to figure 2 , a filling valve in a dry powder fire extinguishing device of the present invention, the filling valve 3 includes a valve casing 6, the center of the valve casing 6 is provided with a stepped center hole, the entrance ...

Abstract

The invention relates to the technology of fire-fighting extinguishing, and discloses a powder extinguishing device. The extinguishing device comprises a filling valve (3), wherein the lower part of the filling valve is connected with a powder bottle (2); and the lower part of the powder bottle is connected with a bottle head valve (1). When used, the extinguishing device with an inverted structure can quickly response to achieve the effect of quick injection.

Description

technical field [0001] The invention relates to fire-fighting and fire-extinguishing technology, in particular to a dry powder fire-extinguishing device. Background technique [0002] At present, most of the dry powder fire extinguishing devices used on traditional vehicles are hand-held dry powder fire extinguishers, and its structure is that the bottle head valve is on the top and the powder bottle is on the bottom. When in use, firstly it takes time to take the fire extinguisher and open the fire extinguisher, and secondly because the bottle head valve is on the top, when it is opened, due to the action of gravity, the speed of spraying dry powder from the fire extinguisher is relatively slow. In addition, traditional fire extinguishers need to be returned to the factory for filling with dry powder and pressurized gas, and the maintenance cost is high. Moreover, in the state of movement such as on-board, the dry powder fire extinguisher is easy to vibrate, and the punctu...
