Detailed introduction

Patent No.: ZL202120360765.1 (Structure), ZL201930728754.2 (Appearance)
Firefighting-specific for petrochemical enterprises

Complies with the requirements of GB60160 (2018 edition) regarding the installation of high-flow fire hydrants in petrochemical enterprises.
Usage: Installed along both sides of roads on fire hydrant lines, primarily designed to supply water to fire trucks or enable high-flow water intake from multiple points.

Scope of application:

"Stable High-Pressure" Fire Water System for Petrochemical Enterprises—Dedicated Products for Unit Areas and Tank Farms

Product features:

● Multiple outlets, high throughput
● Each outlet has its own control valve for convenient use.
● Equipped with a DN150 fire truck suction hose interface for faster water supply to fire trucks
● Dual-plunger drain valve automatically removes residual water from the cavity after the fire hydrant main valve is closed, preventing freezing in winter.
● The main transmission components and seals are made from copper alloy and S30408 material, offering superior corrosion resistance.
● The main valve features a pressure-reducing sealing design, ensuring that the opening force remains unaffected by system pressure.
● JOTUN paint, lasting three years without fading
● Equipped with anti-collision functionality: Even after being damaged by impact, the main valve remains closed, allowing for pressure-rated replacement of the damaged component through above-ground operations.
