Electromagnetic starter, switch valve device and fire extinguishing system for fire extinguishing system

Abstract

The invention discloses an electromagnetic starter for a fire extinguishing system, which comprises an electromagnetic coil assembly, an actuating firing pin, an elastic member and a switch assembly, the electromagnetic coil assembly and the actuating firing pin are matched, and the actuating firing pin is located in the electromagnetic coil assembly after electrification. Under the action of electromagnetic adsorption, it starts to move from the initial position to fire the fire extinguishing system. The elastic part is installed on the firing pin, and the switch assembly is installed on the movement stroke of the firing pin. Electricity, under the action of the elastic member, start the firing pin to return to the initial position. The invention also discloses a switch valve device for a fire extinguishing system and a fire extinguishing system, both of which adopt the above electromagnetic starter structure. The invention has the advantages of simple and compact structure, timely and rapid start-up, remote manual and precise control, no blockage of fire extinguishing injection ports, and high safety.

Description

technical field [0001] The invention mainly relates to the field of fire-fighting equipment, in particular to an electromagnetic starter, a switch valve device and a fire-extinguishing system for a fire-extinguishing system. Background technique [0002] Existing fire extinguishing systems, such as hanging fire extinguishing devices, heptafluoropropane storage tank type fire extinguishing systems, etc., all will be provided with a starter at the fire extinguishing nozzle. When a fire occurs, the starter activates the fire extinguishing device to spray fire. But the existing fire extinguishing system mainly has the following technical problems: [0003] 1. The starter of some existing fire extinguishing systems is a temperature-sensitive glass bulb. When the on-site temperature reaches a certain level, the temperature-sensitive glass bulb will rupture under the influence of high temperature and activate the fire extinguishing system. However, this method requires the site ...

AI Technical Summary

Problems solved by technology

However, this method requires the site to reach a certain high temperature to make the temperature-sensitive glass bubble effective. This makes it impossible to open the fire extinguishing system in time to quickly extinguish the fire, making the fire spread and escalate

The second is that human precise intervention and remote control of the fire extinguishing system cannot be performed. When a fire is discovered, fixed-point and quantitative human intervention cannot be used to extinguish the fire, which reduces the fire extinguishing efficiency and causes a larger fire.

[0004] 2. The starter of some existing fire extinguishing systems is activated by gunpowder blasting

In this way, there is also the need to reach a certain high temperature on site before the temperature-sensitive expansion can take effect, resulting in the inability to open the fire extinguishing system in time for rapid fire extinguishing, leading to an escalation of the fire

The second is that it is also not possible to use human precise intervention and remote control to extinguish the fire

The third is that in this way, when the temperature-sensitive expansion pushes the firing pin to trigger the fire extinguishing system, the firing pin will block the fire extinguishing injection port to a certain extent, or even completely block it, which greatly reduces the effect and efficiency of the fire extinguishing injection, resulting in ineffective fire extinguishing , the fire spread and escalated
