High-efficiency fire-fighting spray head

Abstract

The invention relates to the technical field of fire rescue, and discloses a high-efficiency fire-fighting spray head which comprises a threaded seat, a support below the threaded seat, a splash box at the bottom of the support, a pre-tightening layer at the top of the support, a pre-tightening bolt in threaded connection with the support, and a glass body above the pre-tightening layer. According to the invention, through the design of elastic sheets, when a fire occurs, the air temperature rises, so that heat in a semi-closed space formed by the four elastic sheets can be reflected, accumulated and expanded by the elastic sheets, and the temperature around the glass body rapidly rises to meet the breaking requirement of the glass body; and through the design of torsional springs and heavy blocks, the flow speed of airflow outside the bulging elastic sheets is increased, and under the action that flame consumes air, so that the surrounding air pressure is reduced, the expanded air in the semi-closed space is matched with the torsional springs, the elastic sheets drive the heavy blocks to pull the internally expanded glass body, thus the glass body is broken within a short time, and the spray head quickly reacts in a fire disaster to spray out fire-fighting water.

Description

technical field [0001] The invention relates to the technical field of firefighting and rescue, in particular to a high-efficiency firefighting sprinkler head. Background technique [0002] The fire sprinkler head is a self-starting fire extinguishing device in the fire protection system. It mainly completes the opening and closing action through the glass body set on it. Under normal conditions, the glass body pushes the valve against the water outlet to avoid water from the sprinkler head. In a fire, the rise of the surrounding temperature will cause the thermally sensitive material in the glass body to expand due to heat, causing the glass body to burst and shatter, causing high-pressure water to open the valve, causing the high-pressure water to impact on the splash plate to form a dispersed water curtain to automatically monitor the scene. Extinguishing. [0003] However, there are still some deficiencies in the existing fire sprinkler head, because the sprinkler head ...

AI Technical Summary

Problems solved by technology

[0003] However, there are still some deficiencies in the existing fire sprinkler head, because the sprinkler head is generally installed on the top of the floor, and its installation position is far from the ground, so that after the fire occurs, the speed of temperature rise near the sprinkler head is relatively slow , which makes the fire start to spray water after a long period of time, which delays the timing of fire extinguishing. At the same time, although the design of the splash plate makes the high-pressure water disperse in a wider range, the distance is still limited. , so that the distribution distance of fire sprinkler heads is short, which increases the cumbersome installation of fire protection devices, and the volume of water falling on a unit area is large, resulting in unnecessary waste of water resources
