Fire safety valve

Brief description: The fire safety valve aims to propose a passive fire emergency automatic fuse valve that can timely cut off the transportation of dangerous fluids in pipelines, solve the safety hazards existing in the transportation of high-risk fluids, improve the safety and reliability of operations, and further expand accidents and disasters caused by the inability to close pipelines in a timely manner.

There are various types of control valves currently used in fluid transportation, and significant progress has been made in design technology through years of introduction, digestion, and absorption. However, in high-risk fluid transportation pipeline systems for flammable gases, liquids, and other potentially hazardous media, manual shut-off valves are still commonly used for control. Although in recent years, with the application of electronic technology, electric or pneumatic valve control devices have gradually been used in these fields. However, the control methods of these valves may not be able to be set up at the scene of a fire accident due to the special nature of the environment, or may not be able to be started in a timely manner due to electrical equipment failures, or due to harsh conditions at the scene of the accident, making it impossible for the operator to cut off the pipeline in a timely and emergency manner at or near the cut-off valve. Not only is it unable to cut off the transportation of harmful fluids in the pipeline in a timely manner, but the pipeline cannot be closed in a timely manner, resulting in further expansion of accidents and disasters.

Fire safety valveThe design of the pipeline system is used to automatically cut off or liquid any other potentially hazardous medium when the ambient temperature reaches the set value. Once a fire occurs, theseFire safety valveAutomatically terminate or reduce the supply of liquids, solvents, alcohol, toxic liquids, or any other potentially hazardous media, thereby mitigating the hazards caused by fire accidents. In the event of a fire, the fuse valve will meltdeviceWhen the preset value is reached, it automatically separates and drives the actuator at the top of the valve, causing the valve to change from normally open to normally closed or from normally closed to normally open.Fire safety valveHaving different temperature settings, it can be freely selected according to the actual situation of the project. Generally, the set temperature of the fuse valve should be 30 ℃ higher than the ambient temperature. It is an ideal choice in the import and export system of flammable storage tanks. In addition, the fuse valve can be reused by simply replacing the broken fuse online during use, thereby reducing the cost of use.
