RU95107073A - Gas generator of fire-extinguishing aerosol and method for its equipment - Google Patents

Abstract

FIELD: fire-fighting equipment; applicable in fire protection of technological equipment of block-module objects, particular, units with gas-turbine drive, and also in oil and gas, chemical and other industries employing the fire-hazardous equipment with high vibration loads. SUBSTANCE: gas generator has body, service unit, block of solid aerosol-forming compound and diaphragm, retainer of aerosol-forming block made in form of flexible longitudinal members uniformly spaced over circumference. Longitudinal members contact body internal wall and have depressions rectangular in section and embracing the block. In this case, longitudinal members on one side thrust the bottom and on the other side, the diaphragm. Method for equipment of gas generator provides for placing of flexible longitudinal members uniformly over circumference on the block side surface, before introduction of the block into body and fastening them to one another. EFFECT: reduced probability of damage to the charge under unfavorable operating conditions and to improve reliability of design and process of its manufacture.

Claims (1)

The invention relates to fire extinguishing means and can be used for fire protection of technological equipment of block-modular facilities, in particular units with a gas turbine drive, as well as in oil and gas, chemical and other industries using fire hazardous equipment with a high level of vibration loads. The invention allows to reduce the likelihood of damage to the charge under adverse operating conditions, increase the reliability of the design, improve manufacturability. A gas generator comprising a housing, a consumable assembly, a solid aerosol forming block and a diaphragm is equipped with a checker position lock made in the form of elastic longitudinal elements distributed uniformly around the circumference. The longitudinal elements are in contact with the inner wall of the housing and have recesses of a rectangular profile, covering the checker. In this case, the longitudinal elements abut on the bottom on the one hand, and on the diaphragm on the other. The gas generator equipment method provides that before entering the pieces into the case, elastic longitudinal elements with a cutout for its longitudinal coverage are uniformly applied around its side to the side surface and fastened together.
