Detailed introduction

Patent No.: ZL201620182048.3
Dedicated to the stable high-pressure fire protection system for petrochemical enterprises

Scope of application:

Specialized products for the "stable high-pressure" firewater system in petrochemical enterprises

Product features:

● Specially designed fire hydrant valve: A quick-action switch—simply rotate the wrench 4/5 of a turn to fully open or close.
● Custom-made fire hydrants feature stepless pressure adjustment: The rotation angle of the wrench directly controls and freely adjusts the outlet pressure.
● The custom-made fire hydrant features a plunger-type drain valve that automatically removes any remaining water inside the chamber after the hydrant is closed, preventing freezing during winter.
● The specially designed fire hydrant main valve features positive-pressure sealing, meaning the greater the pressure, the better the seal.
● Combines gun and cannon functions for versatile use.
● The cannon head assembly and the specially designed fire hydrant actuator are both made from S30408 stainless steel or a copper alloy, offering exceptional corrosion resistance.
● JOTUN paint, lasting three years without fading.
