多功能消防水枪设计原理

Design of a New Kind of Multi-function Hydraulic Giant

利用使水流产生预旋的原理使直流水枪增加喷雾功能,调节预旋装置可改变雾化角,并实现直流、喷雾功能的转换。采用圆环缝隙出流,使部分水流从喷嘴四周喷出,形成可调节的伞形开花水流。这一水枪集直流、喷雾、人员保护开花水流于一身,是一种可同时用于扑灭火灾、保护消防人员安全的新型多功能消防水枪。

The straight flow hydraulic giant has the function of spray by making the flow of water pre-swirl. The spray angle can be changed and different function (straight flow, spray) can be switched through adjust the pre-swirl equipment. According to the water out of circular hole, the water spouting from the sides of swirl sprayer can be adjusted to get umbrella shape water flow. This new kind of multi-function hydraulic giant has the function of extinguishing fire and protecting fire fighter. [
