Temperature sensitive line for a temperature-sensing spontaneous starter of a pulse superfine dry powder automatic fire-extinguisher

Abstract

A thermal sensitive wire for temperature-sensing active actuator in a pulsating super fine dried powder automatic fire extinguishing device, characterized by that, the multi-ply cotton yarn in the thermal sensitive wire is coated by a celluloid glue coating, which comprises the medicine and acetic ether solution with the 2-9% concentration of celluloid, whose weight ratio is 1:1, and the medicine powder comprises potassium chlorate and cane sugar, whose weight ratio are (50-75)% and (50-25)%. The wire can be ignited at the strike by the striking rod with gelatinized red phosphorus coated on the top, and can also self-ignite when the environmental temperature reaches 170 deg. C.

Description

technical field [0001] The utility model relates to a thermal wire used for a temperature-sensing self-starter of a pulse ultrafine dry powder automatic fire extinguishing device, which belongs to the technical field of automatic fire extinguishing devices. Background technique [0002] In the prior art, the varieties of dry powder fire extinguishers include portable dry powder fire extinguishers, cart-type dry powder fire extinguishers, suspended automatic dry powder fire extinguishers and suspended electronic remote control fire extinguishers. The first three types of fire extinguishers belong to manual movement and pressure storage type fire extinguishers. When extinguishing a fire, the fire extinguishing agent is sprayed out under the pressure of the compressed gas in the gas storage cylinder. The disadvantage is that the fire extinguisher itself is a pressure vessel, which is prone to explosion and injury accidents. The 2nd, leak air easily, need regular inspection, m...

AI Technical Summary

Problems solved by technology

The disadvantage is that the fire extinguisher itself is a pressure vessel, which is prone to explosion and injury accidents.

Second, it is easy to leak air, needs regular inspection, and maintenance is troublesome

Among them, it is required that the heat-sensitive wire can be ignited with the help of gelled red phosphorus coated on the top of the impact rod when it is hit by the impact rod, and it can also be spontaneously ignited when the ambient temperature of the fire scene reaches 170 ° C. According to the current technology, this problem cannot be solved.
