Abstract

Purpose. Experimental determination of the magnitude of the excess pressure of the explosion in the room when opening the locking devices of rotatable easy-to-reset structures and the study of their behavior during the deflagration explosion in a confined volume.

Methods. At the test site of the Research Institute of Fire Safety and Problems of Emergency Situations of the Ministry of Emergency Situations of the Republic of Belarus, the tests were carried out to determine the opening pressure of locking devices of rotating structures planned for use as easy-to-reset. A prototype gate with three options for fastening the locking device was used as the object of research.

Findings. In the course of the conducted experimental studies the values of the opening pressure of the locking devices and the change in the angle of rotation of the gate leaves during a deflagration explosion were determined. Based on the results of the analysis of data from experimental studies, the influence of the type and number of fasteners on the magnitude of the excess pressure of opening locking devices, as well as the rate of change in the angle of rotation of the rotating structure, was established.

Application field of research. The results of the studies carried out can later be used in the development of a mathematical model of the opening process of rotating easy-to-reset structures and of the methods for determining the opening pressure of locking devices of such structures, followed by amendments to the current technical regulatory legal acts of the system of fire safety regulation and standardization of the Republic of Belarus.
