Quick response adjustable automatic sprinkler arrangements |
摘要 |
The sprinkler arrangements described in the specification include a sprinkler body with an axial passage and an axially movable assembly movable between a sealing position and an open position and including a Belleville washer engageable with a shoulder in the sprinkler body to seal the axial passage in the sealing position and a deflector to distribute water emerging from the passage when the movable assembly is in the open position. A locking assembly which is separable from the sprinkler body normally retains the axially movable assembly in the sealing position and is releasable by a temperature sensitive device at an elevated temperature to permit the movable assembly to move to the open position. In one embodiment the axially movable member has a central post which is slidably guided by a tripod at the outer end of the axial passage. The temperature sensitive device includes a locking disc supported by a temperature responsive element which may be a glass bulb supported in a bulb cage, a plug of fusible material supporting a locking pin, or a solder link retaining the ends of lever members to hold the locking disc in place.
