| 发明名称 | Radiation-activated sprinkler and related methods | ||
| 摘要 | A radiation-activated sprinkler includes a sprinkler body defining a main orifice, the main orifice adapted to couple to a source of pressurized liquid; a deflector coupled to the body; a valve adapted to seat on the main orifice to block the source of pressurized liquid; a linkage mechanism adapted to retain the valve on the main orifice; and one or more fusible links coupled to the linkage mechanism, wherein the one or more fusible links are located substantially externally with respect to the sprinkler body, deflector, and linkage mechanism. The one or more fusible links are adapted to release when exposed to an amount of radiation that exceeds a predetermined threshold, thereby releasing the linkage mechanism from the valve. Other features and related methods are also described. | ||

| 主权项 | 1. A radiation-activated sprinkler, comprising: a sprinkler body defining a main orifice, the main orifice adapted to couple to a source of pressurized liquid; a deflector coupled to the body; a valve adapted to seat on the main orifice to block the source of pressurized liquid; a linkage mechanism adapted to retain the valve on the main orifice; one or more fusible links coupled to the linkage mechanism, wherein the one or more fusible links are located substantially externally with respect to the sprinkler body, deflector, and linkage mechanism; high emissivity paint located on the one or more fusible links; wherein the one or more fusible links are adapted to melt when exposed to radiation at a level of about 3 kW/m2 or more, thereby releasing the linkage mechanism from the valve. | ||
