Description
Technical Field
[0001] The utility model relates to the technical field of cut-off valves, in particular to an adjustable marine emergency cut-off valve. Background Art
[0002] The marine emergency shut-off valve, also known as the "marine valve", is a special valve device specifically used for ships. It is mainly installed on ships such as oil tankers, chemical tankers, and natural gas tankers to quickly cut off pipeline flow during navigation to prevent oil leaks, fires, or other potential accidents. Marine emergency shut-off valves usually have high pressure holding capacity and a complete sealing system to ensure stable and reliable operation even in extreme marine environments. It has a compact structure and is easy to operate. It can quickly cut off the flow of fluid or gas in a short time, thereby quickly responding to emergencies. The working principle of the marine emergency shut-off valve is similar to that of a general emergency shut-off valve. In an emergency, the valve coil is instantly energized, triggering the valve to close quickly and enter a self-locking state. This self-locking mechanism ensures that even if the power is removed, the valve will not automatically reopen, thereby maintaining the safe closure of the pipeline.
[0003] When a leak occurs inside the cabin, if the power supply is damaged and the emergency shut-off valve cannot work, it will cause damage to the hull and personnel. Therefore, the pressure generated by the leak is used to block the inside and cut off the blockage. Utility Model Content
