Description

Fire hydrant capable of preventing water leakage of joint

Technical Field

The invention relates to the technical field of fire fighting equipment, in particular to a fire hydrant capable of preventing water leakage of a joint.

Background

A fire hydrant, generally called a fire hydrant, is a fixed fire-fighting device and mainly used for controlling combustible substances, isolating combustion-supporting substances and eliminating an ignition source. The fire hydrant is generally divided into an overground fire hydrant and an underground fire hydrant, the common fire hydrant of people is generally the fire hydrant installed on the ground, the fire hydrant is mainly used for a fire truck to take water from a municipal water supply network or an outdoor fire-fighting water supply network to put out a fire, and can also be directly connected with a water hose and a water gun to discharge water to put out a fire, the handle needs to be rotated anticlockwise during working, a valve core at the bottom of the fire hydrant is opened, then water in a fire fighting pipeline is pumped out under the action of self water pressure, and the fire is put out through equipment such as the water hose.

The prior fire hydrant has the following defects in the actual use process: firstly, in the actual use process of the existing fire hydrant, a fire fighter needs to unscrew a rotary cover of a water receiving port firstly, then screw a water hose joint of a fire hose so as to screw the fire hose into the fire hydrant, and then open a valve of the fire hydrant to perform water outlet fire extinguishing, the process is complex, certain time is needed to be spent, and in an emergency, life and economic losses are represented by minutes and seconds, the arrangement is not beneficial to fire extinguishing operation in the first time, and certain physical strength of operators is consumed; secondly, in the emergency situation, the operator is very easy to have the water hose joint not screwed in place based on fire fighting, the water hose joint is loosened or water leakage occurs during water spraying fire fighting, the water pressure of the water hose outlet is influenced under the water leakage situation, the water pressure is easily insufficient, and the fire extinguishing work under the butt joint is seriously influenced.
