Outdoor underground fire hydrant

Abstract

The invention relates to an outdoor underground fire hydrant. The fire hydrant comprises a hydrant body, a valve base, a threaded hole base, a screw rod and a water blocking base. A valve chamber is formed in the hydrant body; a water inlet capable of being connected to an underground water supply part of a city is communicated between the bottom of the hydrant body and the valve chamber, and at least one water outlet capable of being connected to a fire protection belt is communicated between the upper end face of the hydrant body and the valve chamber; the valve base is mounted on the waterinlet; the threaded hole base is mounted on the upper portion of the hydrant body relative to the valve base; the screw rod is vertically arranged and is in threaded cooperation with the threaded holebase; the upper end of the screw rod penetrates through the threaded hole base, and the lower end of the screw rod penetrates into the valve chamber; the water blocking base is disposed in the valvechamber, pressed between the valve base and the lower end of the screw rod and used for closing the water inlet. According to the outdoor underground fire hydrant, an operator can rotate the screw rodof the fire hydrant on the ground conveniently and fast, strength is saved, and thus the water inlet of the fire hydrant is closed.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to an outdoor underground fire hydrant. Background technique [0002] The outdoor fire hydrant is a water supply facility installed on the fire water supply pipe network outside the building. It is mainly used for fire trucks to take water from the municipal water supply pipe network or outdoor fire water supply pipe network to put out fires. One of the important fire facilities. Outdoor fire hydrants, traditionally there are above-ground fire hydrants and underground fire hydrants are an outdoor underground fire-fighting water supply facility. It is used to supply water to fire trucks or directly connect with hoses and water guns for fire extinguishing. It is a special facility for outdoor necessary fire water supply. Installed underground, it does not affect the city appearance and traffic. It is composed of body, elbow, valve seat, valve disc, drain valve, valve stem and...

AI Technical Summary

Problems solved by technology

Because the underground fire hydrant is arranged underground, it is difficult to open on the ground and the operation is inconvenient. In the prior art, a rotating rod with a wrench is usually used to extend into the screw rod of the underground fire hydrant, but this method requires the operator to lean out and stretch out. arms, which are not only difficult to exert force, but also pose a danger of falling
