[0002] In the chemical industry, liquefied hydrocarbon storage tanks are key equipment for storing flammable and explosive liquids. Their safety is directly related to production safety and environmental protection. Due to the low boiling point, volatility, flammability and explosiveness of liquefied hydrocarbons, there are high safety risks during storage and transportation. Especially in emergency situations such as fires and leaks, how to quickly reduce the temperature and pressure inside the tanks to prevent the situation from escalating is a major challenge facing chemical companies.
[0003] When traditional water injection valves are used in chemical liquefied hydrocarbon storage tanks, workers need to go to the site to connect the fire water pipe. When emergency water injection is needed, there are problems such as slow response speed, risks to personal safety of personnel, and complicated operation. If the water injection valve cannot be opened quickly and effectively sealed, the water injection effect will be poor or fail, exacerbating fire or leakage accidents. Therefore, the development of a water injection safety valve that can respond quickly, is leak-free, and is easy to operate is of great significance to improving the safety performance of chemical liquefied hydrocarbon storage tanks.

[0018] In addition, one end of the valve body 100 is fixedly connected to the water outlet pipe 500, and the inside of the valve body 100 is fixedly connected to a pushing component 200, where the pushing component 200 includes a telescopic cylinder 201 and a valve stem 202, that is, the valve core 300 is fixedly connected to the valve stem 202, and the piston end of the telescopic cylinder 201 is fixedly connected to the valve stem 202. The telescopic cylinder 201 is matched with an air supply system 203, so that the telescopic cylinder 201 can push the valve core 300 to move linearly, thereby docking with the water outlet pipe 500. The use of a cylinder can ensure that the valve can be quickly opened or closed in an emergency, thereby improving the emergency response speed;
[0019] Furthermore, a sealing groove 303 is provided at the end of the valve core 300, and a sealing ring 304 is fixedly connected to the sealing groove 303. A sealing platform 501 is provided at the end of the water outlet pipe 500.

[0020] Optimally speaking, the valve body 100 is also fixedly connected to a propulsion position sensor 600 and a withdrawal position sensor 700.
