Abstract
A fire sprinkler head (12) has a valve (42) with an X-brace latch (54), and includes a flexible conduit (14). A sprinkler nozzle (16) is secured to a first end of the flexible conduit (14). The sprinkler nozzle (16) includes a first fitting (28), a sprinkler orifice (20) and fusible element (22). A second fitting (40) is secured to the second end of the flexible conduit (14) and includes the valve (42). The valve (42) has a valve element (44) which is moveable from a latched position to an unlatched position. A flexible link (56) extends from the sprinkler nozzle (16) to the X-brace valve latch (54). Breaking of the fusible element (22) releases the flexible link (56) to move from the latched position to the unlatched position, releasing the valve (42) for flow there-through.
Claims14
A flexible dry sprinkler head comprising:
- a flexible conduit having a first end and a second end, the flexible conduit being configured to couple to a fluid supply;
- a sprinkler nozzle mounted at the first end of the flexible conduit, wherein the sprinkler nozzle includes an element that breaks when exposed to predetermined temperatures;
- and
- a valve disposed proximate to the second end of the flexible conduit and having an open state and a closed state, the valve configured to allow fluid from the fluid supply to flow through the conduit when the valve is in the open state and to prevent fluid from the fluid supply from flowing through the conduit when the valve is in the closed state;
- and
- a link that extends between and is coupled to the sprinkler nozzle and the valve, such that breaking of the element causes the link to allow the valve to move to the open state.

- and
- a flexible link extending within the conduit between the sprinkler nozzle and the valve,
- wherein the sprinkler nozzle, valve and flexible link are configured such that breaking of the element causes the flexible link to allow the valve to move from the closed state to the open state.
