FIELD: methods of explosion protection.
SUBSTANCE: invention relates to methods of explosion protection and can be used for technological equipment explosion protection in the case of an emergency. Method of explosion protection with a warning system for the initial phase of an emergency is that the lined cargo gate is movably connected to the valve body by at least three flexible connections, and the breaking element is made in the form of a pressure safety element. On one of the diametrically arranged straps of the membrane assembly of the pressure safety element, a safety indicator is mounted; the latter is a sensor responsive to deformation, whose output is connected to the signal amplifier, and the output of the signal amplifier is connected to the input of the emergency situation personnel warning device. In the valve body, in its cylindrical part, bordering the conical part of the valve, a circular diaphragm is installed with a central hole and with at least three holes, located in its peripheral part. In the upper part, covered with an armored layer of a lined cargo gate, the bottom part of a rod is axiosymmetrically attached to the valve body, the upper part of the rod is located in the central aperture of the diaphragm, and between the lower part of the circular diaphragm and the upper part of the lined cargo gate there is a bushing made from of fragile material that is coaxially fixed to the support rod, such fragile material being triplex glass, the strength of the bushing is calculated for a certain overpressure in the valve. On the side surface of disposable sleeve is fixed an additional safety indicator in the form of resistive strain gauge, the signal from which by the line connection is fed to resistive strain gauge, and from it in a unit of warning system on emergency mode. Emergency situation personnel warning device is multifunctional, and in addition to the audio "loud-speaker" system located directly on the emergency facility, it is additionally equipped with a mobile phone notification system, for example, via the GLONASS space system, for the transfer of urgent information to the state body for the elimination of an emergency.
EFFECT: technical result is to increase the efficiency and reliability of protection of technological equipment from explosions in the event of an emergency.
