AI Technical Summary

Technical Problem

The existing fire monitor head structure is easily damaged by high-speed water flow when mixing foam solution, resulting in incomplete foam structure, low energy utilization, unstable jet, and the foam mixture may generate eddies or deposits at the bottom of the monitor tube, corroding the monitor tube and increasing maintenance difficulty.

Method used

A foam inlet sleeve and a rectifier mechanism connected to the gun barrel body are adopted. Foam and water are mixed at a stable outlet through a foam pump and foam delivery pipe. The rectifier mechanism guides the flow and equalizes the pressure, avoiding eddies and sedimentation, protecting the inside of the gun barrel, and achieving instantaneous shear mixing of foam.

Benefits of technology

Protect the integrity of the foam structure, improve energy utilization, ensure jet stability, reduce maintenance workload, and meet the requirements for maximizing energy efficiency and system response speed.

Abstract

A multifunctional fire monitor head structure belongs to the field of fire protection facility technology. It includes a monitor head body and a flow rectifying mechanism housed within the monitor head body. The key features are: it also includes a foam inlet sleeve communicating with the monitor head body, a foam pump, and a foam delivery pipe. The foam inlet sleeve is fitted onto the monitor head body at the corresponding outlet portion, with its lower part fitting against the outer wall of the monitor head body and its upper part communicating with the outlet portion. The foam delivery pipe connects the foam pump's foam outlet to the foam inlet sleeve, and the foam pump's foam inlet, in use, communicates with the foam supply source through a foam suction pipe. Advantages: It helps protect the integrity of the foam structure, ensures foaming performance, eliminates rotation or flow deviation, and reduces energy loss; it ensures stable outlet flow and jet quality; it helps protect the flow rectifying mechanism (which serves as the monitor core) and significantly reduces the intensity and workload of daily maintenance; it meets the requirement of maximizing the response speed of the energy efficiency system.
