Working Principle
Anti-Freezing Function
The hydrant is equipped with a built-in automatic drain device that automatically closes or drains based on the water pressure inside the plug. When the hydrant is opened and the water pressure is not less than 0.1MPa, the drain valve closes automatically; after the hydrant is closed, the drain valve opens automatically to discharge residual water in a timely manner, preventing freezing.
Anti-Collision Function
Anti-collision components and spring-closed drains are installed to ensure that the hydrant valve head closes quickly in case of impact, preventing water leakage from the pipeline network. Meanwhile, the anti-collision components will not damage the bolt body or valve body when fractured, ensuring the normal use of the hydrant.
Pressure-Regulating Function
The hydrant adopts an automatic pressure-regulating device, which opens in stages when activated. By adjusting the opening height, the water flow distribution is regulated to achieve precise pressure control, ensuring the outlet pressure is adjustable between 0.3MPa and 1.0MPa.
Main Fire-Fighting Components
Fire Hydrant Body: The load-bearing structure that ensures overall strength and durability.
Automatic Drain Device: Controls water pressure changes to realize automatic closing and drainage functions.
Anti-Collision Components: Protect the hydrant from damage and ensure its normal operation even when subjected to impact.
Pressure-Regulating Device: Achieves precise control of the outlet water pressure.
Control Valve: Regulates water flow and pressure.
Auxiliary Parts: Including sealing rings, interfaces, and drains, ensuring tightness and connectivity.
Application Scope
Petrochemical Industry: Meets the fire protection needs of high-risk fire scenes.
Grain Storage and Wood Processing: Prevents fires caused by flammable inventories.
Textile Industry: Protects the fire safety of textiles and production facilities.
Ports, Terminals, and Airports: Serves as key fire-fighting equipment to ensure site safety.
Project Tank Farms: Addresses fire protection requirements for storing flammable materials.
Note: The total height can be customized according to user requirements. The applicable medium is fresh water; additional anti-corrosion treatment is required for seawater applications.
