Mechanical Dry Hydrant
Mechanical Dry Hydrant

The dry-type anti-collision fire hydrant is a water supply facility installed on external firefighting water pipelines. It is primarily used by fire trucks to draw water from municipal or outdoor firefighting pipelines for fire suppression. It can also directly connect to hoses and nozzles to discharge water, making it a critical firefighting asset.

Product Features

High voltage tolerance

The surface of the fire hydrant is coated with a special anti rust layer, which can effectively resist rust and maintain the long-term integrity of the fire hydrant. Quick opening mechanism: Design an easy-to-use quick opening mechanism that can quickly open the fire hydrant even in emergency situations.

Sealing performance optimization

The drainage valve adopts high-quality sealing materials to improve sealing performance and reduce the possibility of leakage. Leakage detection and alarm: Equipped with leakage detection sensors, once the drainage valve leaks, the alarm system can be automatically triggered to notify maintenance personnel for timely handling.

Quick change system

Fire hydrants are made of high-strength materials, offering excellent impact resistance and reducing the risk of breakage. They are designed with a quick-replacement mechanism, allowing for rapid replacement in the event of a breakage, minimizing leakage time and environmental damage.

Rust proof coating

The surface of the fire hydrant is coated with a special anti rust layer, which can effectively resist rust and maintain the long-term integrity of the fire hydrant. Quick opening mechanism: Design an easy-to-use quick opening mechanism that can quickly open the fire hydrant even in emergency situations.
