KOCHETOV'S EXPLOSION-PROOF VALVE WITH ALERT EMERGENCY SYSTEM Russian patent published in 2017 - IPC F16K17/12 F16K17/40 F16K17/16 G08B21/12 

FIELD: machine engineering.

SUBSTANCE: explosion-proof valve comprises a valve body and a thermally insulating discontinuous elements lined cargo shutter movably connected to the valve body. Movable cargo compound is lined with a base shutter valve body is in the form of three rods vertically installed in the holes formed in the peripheral part of the housing shutter lined cargo. Lower part rods are fixed at the base of the valve body and the top have a damping device. A damping device made of vibration damping material such as hard "Agat". The base unit is connected to the damping of the elastomer sleeve and has a central hole through which the rod passes. The sleeve has at least three openings, coaxial with the bar, in which there are elastic elements, such as coil springs, the upper-end face of which, by means of fastening elements, are connected with the base, and the bottom is in unpressed condition and stands for the lower sleeve plane to the distance, determined by the forces developed by the shock wave. Inside the elastic elements coaxially to them, there are additional elastic elements. Their upper end is connected to the base of the damping device, and the bottom - in a free state and acts as the lower plane of the elastic elements on the distance determined forces developed by the blast shock. To the base of the dampener, the sleeve, made of the fast-destroying material, is attached. The security indicator is attached to the outer surface of the sleeve is responsive to the occurrence of an emergency. The indicator is designed as a sensor that responds to a deformation, such as strain gage, whose output is connected to a signal amplifier strain amplifier. Yield strain amplifier is connected to the input device in the system notification of an emergency.

EFFECT: increase the efficiency of the protection of technological equipment from explosions by increasing the damping lined cargo gate.
