Operation

When the Series DS-1 is in service,
water is prevented from entering the
assembly by the Plug & Belleville Seal-
ing Assembly (Ref. Figure 1) in the
Inlet of the Sprinkler. The glass Bulb
contains a fluid that expands when ex-
posed to heat. When the rated tem-
perature is reached, the fluid expands
sufficiently to shatter the glass Bulb,
and the Bulb Seat is released. The
Copper
compressed Spring is then able to ex-
Copper
pand and push the Water Tube as well
as the Guide Tube outward. This action
simultaneously pulls inward on the
Yoke, withdrawing the Plug & Belleville
Seal from the Inlet allowing the sprin-
kler to activate and flow water.
