Fire sprinklers. |
摘要 |
<p>A fire sprinkler (1) has a flow passage (3) for water or other extinguishing fluid closed by a frangible body (4), which may be a simple disc. A separate mechanism reponsive to temperature-rise conditions shatters the frangible body (4), and the fluid then flows from the passage (3) to impinge on a distributor (5) (as in conventional sprinklers). The shattering mechanism is preferably actuated by a shape-memory alloy, preferably in sheet form (11), which can be located below the distributor (5) for maximum exposure to radiant as well as convective heat; it can also be thermally insulated, contributing further to speed of response.</p> |
