Outdoor fire hydrant capable of preventing water leakage

Abstract

The invention relates to the field of fire fighting equipment, and discloses an outdoor fire hydrant capable of preventing water leakage. The outdoor fire hydrant comprises a leakage preventing pipeline, the leakage preventing pipeline is fixedly connected to an underground water conveying pipeline, a leakage preventing cavity is formed between the end faces of the two sides of the leakage preventing pipeline in a communicating mode, a leakage preventing valve element is arranged at the upper end of the leakage preventing cavity, and when the leakage preventing valve element moves upwards, the leakage preventing cavity can be closed. According to the outdoor fire hydrant, the leakage preventing pipeline is installed between the underground water conveying pipeline and a fire hydrant main body, leakage of high-pressure water flow inside the underground water conveying pipeline is effectively blocked through the leakage preventing valve element inside the leakage preventing pipeline, when the ground surface fire hydrant is damaged, the water flow leakage condition is prevented in time, normal operation of traffic is conveniently maintained, meanwhile, the maintenance and installation of the fire hydrant is conducted conveniently, the state of a drainage hole can be controlled according to the opening and closing conditions of a rubber valve element, accumulated water inside the fire hydrant can be drained in time, and the service life of the fire hydrant can be prolonged conveniently.

Description

Technical field[0001]The present invention relates to the technical field of fire protection equipment, and is specifically an outdoor fire hydrant to prevent leakage.Background technique[0002]The existing outdoor fire hydrants take a hard connection to the underground water pipeline, which is not convenient for the installation of outdoor fire hydrants, and existing fire hydrants have a certain amount of water in the use, accelerate the aging of fire hydrants.[0003]Existing fire hydrants are easily leaked by high pressure water flow in the water supply, which will affect road traffic operation after strong impact on external force, which will cause continuous waste of water resources, not convenient for subsequent maintenance and reinstallation, and existing Outdoor fire hydrants After use, it is easy to cause the residue of water, which is easy to cause the fire hydrant to freeze, which in turn affects the life of the fire hydrant.Inventive content[0004]The invention provides an o...
