Retractable telescoping fire sprinkler

a fire sprinkler and telescopic technology, applied in the direction of engine components, valve details, valve arrangements, etc., can solve the problems of not showing the retracting telescopic fire sprinkler in applications, and the sprinklers of the art do not disclose the mechanism for retracting the sprinkler head, so as to achieve the effect of controlling the deployment rate of the telescopic sprinkler

Benefits of technology

"The patent describes a retractable telescoping sprinkler that can control the rate at which it deploys and retracts. The sprinkler can be mounted in different orientations and can be used with different types of sprinkler heads. The sprinkler includes an inner and outer conduit with fluid seals that compress and extend the space between them when the sprinkler extends or retracts. A flow control valve is connected to the space between the conduits to control the flow of fluid. The sprinkler can be extended or retracted without draining the fire-extinguishing media from the sprinkler head. The technical effects of this patent include improved control over the deployment and retraction of a telescoping sprinkler, as well as improved flexibility in installation and the ability to use different types of sprinkler heads."

Embodiment Construction

[0026]A retractable telescoping sprinkler is disclosed. While the sprinkler can be used in any system, the retractable telescoping sprinkler is advantageously used in a dry, preacting sprinkler system. In such a system, the sprinklers are not under pressure, or may be under reduced pressure. In operation, a control systems responding to a sensor detects a condition that requires that the sprinklers be pressurized opens a valve to allow fire extinguishing media—to flow into the sprinklers. Alternatively, if the system has been maintained at some pressure, a sprinkler head may be activated and the control system will deploy the sprinklers in response to the pressure drop. In some cases, the sprinkler heads are open, and fire-extinguishing media can flow from the open heads when the control valve is opened. In other systems, each sprinkler is closed with a thermally sensitive valve. In such a case, the control system will supply fire-extinguishing medium to the sprinkler head under pre...

Abstract

A retracting telescoping automatic fire sprinkler is disclosed. In a dry system, the sprinkler extends to its operating position under system pressure that is applied in response to a preaction signal. When system pressure is removed, as in after a test is completed, the sprinkler automatically retracts to its original position.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to pre-acting retractable extending fire sprinklers.[0003]2. Background Information[0004]Fire protection sprinklers may be operated individually, e.g. by a self-contained thermally sensitive element, or as part of a deluge system in which fire retardant fluid flows through a number of open sprinklers, essentially simultaneously. Fire retardant fluids may include natural water or appropriate mixtures of natural water and one or more additives to enhance fire-fighting properties of a fire protection system.[0005]Fire protection sprinklers generally include a body with an outlet, an inlet connectable to a source of fire retardant fluid under pressure, and a deflector supported by the body in a position opposing the outlet for distribution of the fire retardant fluid over a predetermined area to be protected from fire. Individual fire protection sprinklers may be automatically or non-automatically ope...
