소방호스의 기능향상을 위한 회전연결구에 관한 연구

Fire hose is that use essential as is indispensable in fire attack that keep life and property from fire. Therefore, should be enough safe at use is in the performance and it is required that also treatment is easy and long-lived and repair administration should be easy. Condition by use is not necessarily equal and performance that is required by the usage because is used in various kinds other condition according to fire occurrence place and situation etc. is various. When fire broke out, connect fire hose to the fire hydrant of outlet. This time, environmental leading person who can bottleneck on surroundings of the fire hydrant of fire suppression is case. Distance enemy to that do the fire hydrant to flume of that do facilities leaving alone and the fire hydrant around that do the fire hydrant interior door difference differential and fire occurrence place etc. Can enter to example. Such environmental factor is real condition that fire hose of that is curve or hazardous factor that do not display function as fire hose properly engendering twisted phenomenon is latented. In this treatise 720 turning connection nine at interior outside of the fire hydrant practical use fire hose curve or present method that problems of that get snarl are not happened. Practical use of this turning connection nine is thought to contribute to minimise elevation and human of batting average of early fire city suppression and physical damage making source of a stream`s supply smoothly to fire hose.
