FIELD: explosion-proof devices.
SUBSTANCE: invention relates to explosion-proof devices and can be used for the process equipment explosion protection in the event of the emergency occurrence. Explosion protection device with safety valve containing valve body, lined load gate movably connected to the valve body, rupture element made in the form of a membrane safety device, on one of diametrically located plates of membrane safety device of membrane unit safety indicator in form of sensor responding to deformation is fixed, installing the circular diaphragm in the valve body, at that, in the upper part covered by the armored layer of the lined load gate, axisymmetric to the valve body, securing the rod, which upper part is located in the diaphragm central aperture, and between the circular diaphragm lower part and the lined load gate upper part, on the support rod, coaxially to it, installing the bushing made of rapidly destructing material.
EFFECT: technical result is increase in the efficiency and reliability of the process equipment protection against explosions.
