Abstract
The application discloses a safety blocking device, in particular to a safety blocking device for gravity conveying pipeline of flammable and explosive materials, and belongs to the technical field of dangerous material conveying equipment design and manufacturing. The safety blocking device for gravity conveying pipeline of flammable and explosive materials has short response time and can extinguish the fire in the conveying pipeline after being cut off. The safety blocking device comprises a material conveying pipeline, and further comprises a quick cutting mechanism and a fire extinguishing sealing system. The material conveying pipeline is quickly cut off by the quick cutting mechanism according to the requirement, and the remaining open fire in the material conveying pipeline at both ends of the quick cutting mechanism is extinguished by the cooperation of the fire extinguishing medium sprayed by the spray head inlaid on the quick cutting mechanism of the fire extinguishing sealing system, and meanwhile, the pipeline forms a sealing effect at the valve with the assistance of the fire extinguishing medium.
