The invention relates to a rotating type explosion flame isolating device and belongs to the technical field of explosion isolating and restraining. The isolating device comprises a shell and an explosion isolating valve arranged in the shell. The explosion isolating valve is located at the gas input end of the shell. One end of the explosion isolating valve is fixedly connected with a locking rod. One end, close to the explosion isolating valve, of the locking rod is hinged to the shell, and the other end is provided with a balance weight. A limiting device is arranged on one side of the locking rod and fixedly connected to the shell. When the locking rod drives the explosion isolating valve to rotate to the preset angle, the explosion isolating valve turns off a channel, and the lockingrod triggers the limiting device to be locked. An opening is formed in the middle portion of the shell. An explosion relief opening is formed in the opening, located in the upper portion of the explosion isolating valve and fixedly connected to the shell. The isolating device solves the problems that the opening and closing degree of an explosion isolating valve in the prior art cannot be adjusted, the isolating device cannot be used independently, and the structure is complex, and meanwhile the isolating device has the characteristics of being low in operation cost and high in reliability.
Description
technical field [0001] The invention belongs to the technical field of explosion isolation and suppression, and relates to a rotary explosion flame isolation device. Background technique [0002] According to incomplete statistics, in industries such as industry, trade, and hazardous chemicals, many businesses involve the production, storage, and transportation of industrial combustible gases or dust. In recent years, there have been many gas and dust explosion accidents, which not only caused huge loss of life and property, but also caused bad social impact. [0003] At present, there is a lack of cost-effective explosion control equipment in places where flammable gas and dust exist. [0004] The explosion flame isolation device is one of the effective explosion control equipment, which is used to isolate the explosion flame generated in the flammable gas and dust explosion pipeline, and release the explosion shock wave from the explosion vent, so that the explosion flame...
