  • Patent number: 10561871
    Abstract: A ceiling-only dry sprinkler system configured to address a storage occupancy fire event with a sprinkler operational area sufficient in size to surround and drown the fire. The system and method preferably provide for the surround and effect by activating one or more initial sprinklers, delaying fluid flow to the initial activated sprinklers for a defined delay period to permit the thermal activation of a subsequent one or more sprinklers so as to form the preferred sprinkler operational area. The sprinklers of the operational area are preferably configured so as to provide sufficient fluid volume and cooling to address the fire-event with a surround and drown configuration. The defined delay period is of a defined period having a maximum and a minimum. The preferred sprinkler system is adapted for fire protection of storage commodities and provides a ceiling only system that eliminates or otherwise minimizes the economic disadvantages and design penalties of current dry sprinkler system design.

    Abstract: A dry sprinkler is provided that includes a conduit with a fluid inlet and a fluid outlet, a valve positioned near the fluid inlet and a fire sprinkler head that is positioned near the fluid outlet. The fire sprinkler head is operably connected to the valve by a tie. When the fire sprinkler head reacts to an elevated temperature condition, the tie is engaged and is operable to open the valve. In a normal state, before the fire sprinkler head reacts, the tie can be unbiased toward the fire sprinkler head. The tie can also be non-rigid and/or in a non-compressed state within the conduit. The conduit of the dry sprinkler can be flexible.

  • Patent number: 10426983
    Abstract: A fire sprinkler system is described which includes a piping system having at least one dual-use pipe providing both an air conveying inlet and a fire extinguishing fluid conveying outlet. The pipe has at least one air sampling opening allowing ambient air flow into the pipe and at least one fire sprinkler for ejecting a fire extinguishing fluid from the pipe in the event of a fire. An air sampling detector is fluidly connected to the pipe and tests the ambient air within the pipe to detect the presence of the fire. A valve, disposed between the source of the fire extinguishing fluid and the pipe, is in communication with the air sampling detector and operable to open, upon detection of the fire based on the ambient air tested by the air sampling detector, in order to fill the pipe with the fire extinguishing fluid.

  • Publication number: 20140102730
    Abstract: A dry sprinkler assembly includes a housing, a sprinkler head assembly with a sprinkler head and a trigger assembly, and an actuator assembly. The actuator assembly has a sealing subassembly for sealing the inlet port of the housing and is operatively coupled to the trigger assembly such that the sealing subassembly releases the sealing of the inlet port in response to the trigger assembly releasing its closure at the outlet opening. The sealing subassembly moves in a linear path substantially parallel with the central longitudinal axis of the housing when releasing the sealing of the inlet port wherein the flow of fire suppressant through the inlet port and into the fluid flow passage is substantially unimpeded.

  • Patent number: 8662191
    Abstract: A sprinkler assembly can utilize an adapter having straight threads and an internal sealing member therein to attach the sprinkler to a piping system. The sprinkler may include tapering threads that engage with the straight threads of the adapter and compress the sealing member therein to form a fluid-tight seal. A sprinkler assembly can utilize a fitting that is attached to an extension member containing the sprinkler. The fitting allows the sprinkler and extension member to be coupled to the piping system with a solvent weld. A sprinkler assembly can utilize an attachment system to couple a sprinkler attached to an extension member to a piping system. The attachment system can include a first fitting attached to the connection member, a second fitting attached to the piping system, and a clamping member to clamp the two fittings together.

  • Publication number: 20130319696
    Abstract: A flexible dry sprinkler includes a flexible tube having an inlet attached to a first end, the inlet defining an inlet orifice operatively sealed by an inlet seal assembly. An outlet is attached to the second end of the flexible tube, and defines an outlet orifice operatively sealed by an outlet seal assembly. A flexible linkage extends from the inlet to the outlet through the flexible tube, and is constructed to operatively release the inlet seal assembly responsive to axial translation of the flexible linkage from a first position to a second position. The flexible linkage is supported by the outlet seal assembly in the first position and wherein the flexible linkage is constructed to axially translate toward the outlet when the outlet seal assembly is released.
