Abstract

The invention relates to an elastically-sealed automatic sprinkler head. The automatic sprinkler head comprises a body, a thermosensitive element, an adjusting bolt, a water splashing deflector, a ball seat, an elastic gasket, a cover-shaped elastic sheet, an inner sealing washer, an outer sealing washer, a sealing washer, a sealing ring and the like, wherein the elastic gasket, the ball seat and the cover-shaped elastic sheet can be selectively and respectively inosculated and equipped with the inner sealing washer, the outer sealing washer, the integrated sealing washer and the sealing ring with different section shapes such as a single-lip shape, a double-lip shape, an outward-turned single-lip shape, an outward-turned double-lip shape and an L shape. By virtue of different sealing surface types, the non-extrusion type elastic sealing as well as hydraulic-power sealing and hydraulic-pressure sealing of the automatic sprinkler head can be realized, the required sealing surfaces are reduced, the assembly pretightening force of the sealing surfaces and the normal temperature creep value of non-metal materials are reduced, long-time sealing performance can be achieved, and besides, when the thermosensitive element is opened and released in a fire, sealing elements are not adhered to the sealing surfaces of the body and can be separated easily, so that the sprinkler head can automatically spraying water for extinguishment.

Description

technical field [0001] The present invention relates to fire protection products, especially elastic sealing automatic sprinkler head. Background technique [0002] In the existing automatic sprinkler system, the sealing of the automatic sprinkler head is mainly to use a flexible O-shaped rubber ring, which is matched with a rigid ball seat for sealing. This kind of sealing, although the sealing is better, but because the rubber ring, etc. Non-metallic materials have room temperature creep and aging properties. Under the perennial large assembly seal pre-tightening force and water pressure extrusion, as time goes by, they will lose elasticity and sealing performance, and even the sealing surface and the body , ball seats, etc. are bonded together, causing the automatic sprinkler head to fail to automatically open in the event of a fire, delaying water spraying to extinguish the fire. In the prior art, there is also an elastic sealing structure of the automatic sprinkler hea...
