Abstract
A fire sprinkler discharge control device for preventing fluids from being emitted from a fire sprinkler without having to turn off a fluid supply to the fire sprinkler. The control device may be formed from one or more bladders adapted to contain a fluid and one or more valves for passing fluids into and out of the bladder. The bladder may be adapted to fit between a support structure of a fire sprinkler and an exhaust port. Once in position, the bladder may be inflated to cut off fluid flow from an exhaust port of the fire sprinkler.
Claims25
A fire sprinkler discharge control device, comprising:
- at least one bladder adapted to fit between a support structure of a fire sprinkler and an exhaust port of a fire sprinkler for sealing the exhaust port of the fire sprinkler.
A fire sprinkler discharge control device, comprising:
- at least one outer bladder adapted to fit between a support structure and an exhaust port of a fire sprinkler;
- at least one inner bladder impermeable to fluids and positioned in the at least one outer bladder;
- and
- at least one valve coupled to the at least one bladder for controlling flow of a fluid into and out of the at least one bladder.
A method of controlling discharge of fluids from a fire sprinkler, comprising:
- inflating a fire sprinkler discharge control device positioned proximate to an exhaust port of a fire sprinkler so that at least a portion of at least one bladder forming the fire sprinkler discharge control device contacts the exhaust port and prevents at least a substantial portion of the fluids from being discharged from the exhaust port of the fire sprinkler.
