Problems solved by technology

[0003] However, the existing nozzles of fire extinguishers often have a common hollow structure inside. When spraying, the spraying area is relatively concentrated, and the spraying is rapid and the spraying time is short. The fire extinguishing effect is often not up to expectations.

Embodiment Construction

[0020] Such as figure 1 The shown spiral nozzle that can be used in automatic fire extinguishers includes a nozzle 1 and a spiral body 2 disposed inside the nozzle 1. The spiral body 2 is formed by rotating a rectangular sheet with a cutout 3 at each end. The nozzle system of the automatic fire extinguishing system is based on the principle of aerodynamics. When the automatic fire extinguishing system is started, the agent inside the fire extinguishing system will generate a resistance and a tangential force when it passes through the spiral body in the nozzle under the action of pressure. The resistance can prolong the life of the agent. The tangential force can expand the fire extinguishing range of the automatic fire extinguishing system. Finally, the fire extinguishing effect of the automatic fire extinguishing system is increased.

[0021] Such as figure 2 As shown, the nozzle 1 is cylindrical, and a hexagonal snap ring 4 is fixed in the middle of the outside.

Abstract

The invention discloses a spiral-type nozzle applicable to automatic fire extinguishers, which comprises a nozzle (1). The nozzle (1) is characterized by also comprising a spiral body (2) arranged in the nozzle (1). The spiral body (2) is shaped through rotating a rectangular sheet. The two ends of the spiral body (2) are respectively provided with a notch (3). The spiral-type nozzle applicable to automatic fire extinguishers is designed based on the principle of gas dynamics. When an automatic fire-extinguishing system is started, a medicament inside the fire-extinguishing system is driven to pass through the spiral body in the nozzle under the effect of the pressure to generate a resistant force and a tangential force. Under the effect of the resistant force, the spraying period of the medicament is prolonged. Under the effect of the tangential force, the fire-extinguishing range of the automatic fire-extinguishing system is expanded. Finally, the fire-extinguishing effect of the automatic fire-extinguishing system is improved.

Description

technical field [0001] The invention relates to the field of fire fighting equipment, in particular to a spiral nozzle which can be used for an automatic fire extinguisher. Background technique [0002] In the current fire-fighting equipment market, nozzles are widely used in various fire-fighting equipment, such as fire extinguishers and fire sprinklers. It can have a longer spray distance to achieve a good fire extinguishing effect. At the same time, it also prevents firefighters from getting too close to the fire scene, which greatly improves the safety of fire fighting. [0003] However, the existing nozzles of fire extinguishers often have a common hollow structure inside. When spraying, the spraying area is relatively concentrated, and the spraying is rapid and the spraying time is short, so the fire extinguishing effect is often not up to expectations. Contents of the invention [0004] The technical problem to be solved by the present invention is to improve a sp...
