Indoor intelligent rapid emergency fire hydrant

Abstract

This invention relates to the field of fire protection equipment technology, and in particular to an indoor intelligent rapid emergency fire hydrant. Its structure includes: a fire hydrant box, with an inlet pipe connected internally to the box, a vertically mounted switch valve on the inlet pipe, a loop-shaped flow buffer section above the switch valve, and an inching valve and a main valve inside the loop-shaped flow buffer section, as well as a water pressure trigger cooperating with the main valve. The beneficial effect is that by setting a delayed inching mechanism composed of the inching valve and the main valve, and configuring a water pressure trigger cooperating with the main valve inside the loop-shaped flow buffer section, after the switch valve opens, it first outputs 30% to 35% pre-charged water flow after a 12-second delay, and then the main valve fully opens after a 7 to 9-second delay. This provides the operator with approximately 19 to 21 seconds of buffer time, allowing them to independently complete hose deployment, positioning, and aiming actions, solving the problem of traditional fire hydrants requiring two operators.
