Description

Technical Field

[0001] The utility model relates to the technical field of emergency cutting, in particular to an emergency cutting device. Background Art

[0002] Fire refers to a disastrous combustion phenomenon that is out of control in time or space. Among various disasters, fire is one of the most frequent and common major disasters that threaten public safety and social development. Human beings can use and control fire, which is an important sign of civilization and progress. Therefore, the history of human beings using fire and the history of fighting against fire are coexistent. While using fire, people constantly summarize the laws of fire occurrence and try to reduce fire and its harm to humans as much as possible. When encountering a fire, people need to escape safely and as quickly as possible.

[0003] When an oil pipeline or a pipeline with harmful media flowing is within the range of a fire, once a leak occurs, it is easy to cause greater losses and bring harm. For this reason, we propose an emergency shut-off device. Utility Model Content

At this time, the first spring 18 will restore its original length, so that the plug rod 19 slides downward on the inside of the cylinder 4, and then drives the sealing plate 17 to slide downward on the inside of the valve body 1, thereby sealing the outlet 2, so that the valve body 1 no longer forms a passage, so that the medium in the pipeline is blocked, and the continuous spread of fire is avoided. After use, the device is pulled out of the first connecting rod 5 and the second connecting rod 6 from the top of the cylinder 4, and then the first connecting rod 5 and the second connecting rod 6 are pulled in opposite directions, and then the first connecting rod 5 and the second connecting rod 6 are disassembled, and then a new rubber block 8 is taken and re-fixed between the first connecting rod 5 and the second connecting rod 6, and reinstalled on the device, so as to facilitate the recycling of the device, thereby solving the problem that when the oil pipeline or the pipeline where harmful media flows is within the fire range, once a leakage occurs, it is easy to cause greater losses and bring harm.
