The fusible link valve for diesel generator sets is designed to automatically shut off flammable gases or liquids, and any other potentially hazardous media in the piping system when the ambient temperature reaches a set value. Once a fire or explosion occurs, the valve will automatically shut off the supply of flammable gases or liquids, or any other potentially hazardous media to stop or reduce the hazards caused by fire and explosion accidents.
The fusing link valve for the diesel generator set includes the valve body and actuator, and the valve body and actuator are fixed by a fixed bracket/yoke. The actuator of the fused valve includes the shaft, fusible link, manual/gear operator, actuator protection cover, limit switch, etc. The fusible link valve can be reused by replacing the disconnected fusible link in the process of use, which reduces the cost of use.
China’s shut-off safety valve technology has made great strides in development through the continuous introduction of new technologies. But for flammable gases or liquids, solvents, alcohol, toxic liquids, or any other potentially dangerous media in the high-risk system, it is still common to use manual shut-off valves, or electric/pneumatic shut-off valves. But the control of these valves, in the process of fire, explosion, and other accidents, due to the special nature of the environment, which causes the operator can not quickly close the valve in an emergency, or due to the harsh conditions of the accident site can not be close to the shut-off valve, or cause damage to the electric, pneumatic shut-off valve system function, or when the shut-off valve coil is accidentally charged, the shut-off valve will automatically open, which causes in the inability to play an emergency cut off the pipeline purpose. It may cause flammable gases or liquids, solvents, alcohol, toxic liquids, or any other potentially dangerous media leakage, there may be a certain amount of personal injury to the staff who implement the shutdown operation, or lead to the inability to close the pipeline in time and further expand the accident disaster.
The Fusible link valves are designed to automatically shut off piping systems for flammable gases or liquids, solvents, alcohols, toxic liquids, or any other potentially hazardous media when the ambient temperature reaches a set value. In the event of a fire or explosion, these valves will automatically stop the supply of flammable gases or liquids, solvents, alcohols, toxic liquids, or any other potentially hazardous media, ending or reducing the hazard caused by a fire or explosion. In the event of a fire, the fuse of the fusible link valve will automatically disengage(link melts) when a preset value is reached, which automatically drives the actuator at the top of the valve, turning the valve from normally open to closed(fail valve close/FC) or normally closed to open(fail valve open/FO). The fusible link valve has a wide range of temperature setting values, which can be freely selected according to the actual situation of the project. In general, the setting temperature of the fusible link valve should be greater than the ambient temperature of 30℃. It is a very ideal solution in the inlet and outlet system of flammable storage tanks.
We were commissioned by the distributor of HIMOINSA diesel generator sets to retrofit fuse valves on 13 sets of 1500KW high-pressure generator units for a new project. The selected fusible link safety valves are a kind of valve for chemical pipeline flammable medium fire prevention, which does not need air or power supply, when the ambient temperature reaches ≤80 to 100℃, the alloy material of fusible link melts, the mechanical piece disconnected, the spring returns drives valve closes, which effectively prevents the expansion of the situation and protects the safety of storage tank/equipment and personnel.
The fusible link valve is a kind of valve that can detect the temperature by itself and can close automatically when a fire occurs.
In this case, HIMOINSA distributors highly praised our products and service and said they would cooperate more on diesel generator sets in the future.
