The invention provides a distributed point-by-point follow-up spray type temperature-control fire-fighting
system with a memory
alloy spring and belongs to the field of temperature-control spray fire-fighting gridding technologies. The distributed point-by-point follow-up spray type temperature-control fire-fighting
system is characterized by comprising a manual
check valve for gridding concentrated compensation control, a parallel connection distributed type auxiliary spray fire-fighting valve group, a compression spring control type main spray fire-fighting valve and a connecting component based on a three-way
pipe hoop, wherein the auxiliary spray fire-fighting valve group is controlled by the temperature of the memory
alloy spring and used for point-to-point control, and the compression spring control type main spray fire-fighting valve is used for point-by-point follow-up spray. In the
normal state, the
check valve is closed manually, all auxiliary spray fire-fighting valves connected in parallel and the main spray fire-fighting valve are closed, when the ambient temperature of one or more auxiliary spray fire-fighting valves rises to the acting temperature of the memory
alloy spring, the corresponding auxiliary spray valves are opened, the main spray fire-fighting valve is opened therewith, and spray is achieved; and if human intervention is needed, the
check valve is opened manually, the other paths of auxiliary spray valves distributed in parallel still can perform the spray operation. The distributed point-by-point follow-up spray type temperature-control fire-fighting
system achieves point-to-point point-by-point spray in large space, and manual spray can be performed when a failure happens.
