Embodiment 1

[0019] Such as figure 1 As shown, the structure of the fire extinguisher nozzle is as follows: including the nozzle and the pipe body 10 arranged inside the nozzle. The pipe body 10 is provided with three layers of pipe walls, and the adjacent pipe walls are connected by guide pieces along the axial direction of the pipe body. The aperture of the innermost pipe wall 20 of the pipe body 10 becomes smaller from the fire extinguishing agent inlet end to the outlet end, and the aperture diameter of the second layer pipe wall 30 of the pipe body 10 becomes larger from the fire extinguishing agent inlet end to the outlet end.

[0020] In addition, in this embodiment, the guide fins are uniformly arranged along the circumferential direction of the tube body 10 . The advantage is that the fire extinguishing agent sprayed by the fire extinguisher is evenly sprayed in the circumferential direction. There are at least two guide pieces between adjacent pipe walls. The advantage is that ...

Abstract

The invention discloses a fire extinguisher nozzle structure. The fire extinguisher nozzle structure comprises a nozzle, and further comprises a pipe body arranged in the nozzle, wherein the pipe body is provided with three layers of pipe walls; the adjacent pipe walls are connected through guide pieces in the axial direction of the pipe body; the aperture of the pipe wall on the innermost layer of the pipe body is decreased from an inlet end to an outlet end of a fire extinguishing agent; and the aperture of the pipe wall on the second layer of the pipe body is increased from the inlet end to the outlet end of fire extinguishing agent. The invention aims to provide the fire extinguisher nozzle structure for solving the problem of incapability of injection at a larger distance in prolonging of the fire extinguisher injection time and widening of the fire extinguishing range in a traditional fire extinguisher nozzle.

Description

technical field [0001] The invention relates to a fire extinguisher nozzle structure. Background technique [0002] In today's society, fire accidents have become one of the most harmful and frequent disasters in human daily life. Statistics in recent years show that fire accidents involving mass death and mass injury occur almost every year. On average, 10,000 fires occur every year in the world, and 800 people die in fires every day. In China, the average annual direct loss caused by fire is 1.55 billion yuan, 2393 people die, and an average of 6 Chinese citizens die due to fire every day. Therefore, it is imminent to establish a complete and scientific new fire protection system. [0003] According to relevant scientific research data, in the process of indoor fire, it is generally a small fire at first, but the smoke is relatively large. It takes 3 to 5 minutes from the initial fire to the formation of a large fire. If you have a simple fire extinguisher at home and c...
