Embodiment Construction

[0026] figure 1 The sprinkler of the present invention is shown in a first, non-operating mode. The sprinkler comprises a nozzle holder 1 and a glass needle tube 18 mounted on the nozzle holder by means of a support 19 . A nozzle base 1 comprising a plurality of nozzles 2 is mounted on a support body 3 with screw connections, and the support body 3 is then mounted on a pipeline 4, which supplies fire extinguishing agent to an inlet 5 in the support body 3, And further supply to the upper zone 22 of the nozzle seat.

[0027] The support body 3 is enclosed in a cylindrical jacket 6 . The jacket 6 is movable relative to the support body 3 . A pressure chamber 7 is arranged between the jacket 6 and the support body 3 . Since the jacket 6 has a second inner cylindrical surface 8 whose diameter is larger than the first inner cylindrical surface 9 of the jacket, the pressure chamber 7 is formed. The channel between the cylindrical surfaces 8 and 9 defines a shoulder 10 . The pr...

Abstract

The invention relates to a sprinkler which includes a support body (3), at least one nozzle (2), a thermally activated release device (18) and a hood (13) which is locked in a protective position (14 ,17) In front of the above-mentioned nozzle, so as to mechanically protect the release device when the sprinkler is in non-working mode, and can be moved to a release position away from the nozzle to expose the release device. When the sprinkler is in working mode, the nozzle is in the release device After release, the fire extinguishing agent can be sprayed, and the support body includes an inlet (5) for introducing the fire extinguishing agent. In order that the sprinkler can be used in environments with deep exposure to dust and impurities, and in order not to start spraying extinguishing agent when the sprinkler is exposed to heat while its cover (13) is in the protective position, the sprinkler includes a device (6) , which is movable relative to the support body (3) and is arranged to move relative to the support body under fluid pressure and to exert a force on the locking areas (14, 17) causing the locking areas to open, thereby moving the cover to the above-mentioned release position to expose the release device (18) and to place the sprinkler in the standby mode, wherein the release device (18) is not actuated and is thus able to react to heat and achieve the release of the sprinkler and to set the sprinkler in the operating mode.

Description

Background of the invention [0001] The present invention relates to a sprinkler comprising a support body, at least one nozzle, a heat-activated release device and a cover which is locked in a protective position in front of said nozzle when the sprinkler is in an inoperative mode, so that Mechanically protect the release device, when the sprinkler is in the working mode, the cover can move to a release position, at this time it leaves the nozzle to expose the release device, and after the release device is released, the nozzle can spray out the fire extinguishing agent, the support body Includes an inlet for introducing extinguishing agent. [0002] Such sprinklers are known, for example, from US 3,727,695, US 4,014,388 and US 4,880,063. For example, covers are used to mechanically protect the release (US 3,727,695), or to provide an aesthetic sprinkler type that is hidden in the ceiling when in non-operating mode (US 3,727,695 and US 4,014,388). In such concealed sprinkler...
