Abstract

The invention provides an overpressure relief device with controllable opening modes, which has automatic, manual and remote control opening modes. The device provided by the invention can realize the function of automatic release of overpressure, that is, when the pressure in the fuel depot rises to the set threshold, it can automatically open the cover to discharge the high-pressure gas to the safety channel; at the same time, it also has the function of manual and remote control opening, That is to say, regardless of whether the pressure in the warehouse reaches the set threshold or not, it can be opened manually or remotely, and the toxic and harmful gases in the warehouse can be released to the safe passage outside the warehouse. The device has the characteristics of reliable locking, fast opening, controllable opening mode, simple structure and convenient maintenance.

Description

technical field [0001] The invention relates to an overpressure relief device with automatic, manual and remote control opening modes, which belongs to the field of security of fuel depots. Background technique [0002] A large amount of liquid compressed gas (flammable liquid hydrogen and combustion-supporting liquid oxygen, etc.) is usually stored in the fuel depot, and they are stored in seamless steel cylinders in a liquid state and under high pressure. Therefore, the fuel depot is a flammable and explosive high-risk place. The fuel depot is usually equipped with a fire alarm system, pressure detection and video monitoring system, etc., and is usually unattended. The gas in the seamless steel cylinders stored in the fuel depot will be released quickly due to accidents, and even cause combustion and explosion, which will cause the temperature in the fuel depot to rise and automatically trigger the fire system to alarm and extinguish the fire. However, the rapid release, ...
