Detailed description of the invention
Being described further the utility model dry sprinkler below in conjunction with accompanying drawing:
Embodiment one: as shown in Figures 1 to 3, the utility model dry sprinkler, wherein, include nozzle component, one end withstands on the top cover seat 1 in nozzle component, the interior push pipe 2 being spirally connected with top cover seat 1 and be socketed in the extension tube attached 3 that interior push pipe 2 is outer and be spirally connected with nozzle component, one end of above-mentioned interior push pipe 2 is provided with rotating piston 4, this rotating piston 4 is by a split pin 5 and interior push pipe 2 pin joints, above-mentioned extension tube attached 3 one end are bolted with seal holder ring 6, sealing seat ring 6 is enclosed within outside rotating piston 4, between above-mentioned seal holder ring 6 and rotating piston 4, seal by sealing gasket 7, the inwall of above-mentioned extension tube attached 3 is provided with step, this step place is provided with packing ring 8, between above-mentioned top cover seat 1 and packing ring 8, be provided with compressed spring 14, this spring 14 is socketed on interior push pipe 2, on the tube wall of above-mentioned interior push pipe 2, have limbers 9.
Between above-mentioned extension tube attached 3 and nozzle component and between seal holder ring 6 and extension tube attached 3, be provided with sealing ring, to improve overall sealing.
Above-mentioned nozzle component comprises that a ball seat cover 10 and one end are plugged in the glass column 11 on ball seat cover 10, in this glass column 11, be provided with liquid, one end of above-mentioned top cover seat 1 withstands on above-mentioned ball seat cover 10, above-mentioned top cover seat 1 one end faces are provided with through hole 12, this through hole 12 communicates with the inner chamber of above-mentioned interior push pipe 2, offers the inlet opening 13 communicating with through hole 12 on the outer wall that above-mentioned top cover is done; Above-mentioned sealing gasket 7 is the elastic sealing gasket 7 of one side indent, and inner concave is above-mentioned rotating piston 4 dorsad, and above-mentioned sealing gasket 7 is softened state under the thrust of rotating piston 4.
When fire does not occur or do not reach explosion glass column 11, glass column 11 one end are stuck on ball seat cover 10, and the other end is to withstand with the dog screw on nozzle component framework 15.Top cover seat 1 one end contacts with ball seat cover 10, the other end is threaded with interior push pipe 2 with hickey, interior push pipe 2 other ends are connected with rotating piston 4 with split pin 5, specifically, rotating piston 4 has coaxial corresponding jack with on interior push pipe 2, split pin 5 is plugged in jack, and like this, rotating piston 4 just can be connected to interior push pipe 2 one end by split pin 5; The framework 15 of nozzle component is to be spirally connected with extension tube attached 3, after being spirally connected, the spring 14 that is socketed in interior push pipe 2 one end is compressed, sealing gasket 7 between rotating piston 4 and seal holder ring 6 is also softened state under the thrust of rotating piston 4, thereby has ensured that the seal holder ring 6 being connected with water pipe can not make water enter in interior push pipe 2.
In the time of breaking out of fire, heated liquid in glass column 11 expands, in the time reaching nominal temperature, the liquid expanding makes glass column 11 explosions, now, ball seat cover 10 loses the support of glass column 11 and drops, compressed spring 14 resets, promoting top cover seat 1 moves to nozzle component direction, because top cover seat 1 and interior push pipe 2 are spirally connected, therefore, interior push pipe 2 can move along with the moving direction of top cover seat 1, after interior push pipe 2 moves, interior push pipe 2 moves by split pin 5 driven rotary plugs 4, now, sealing between rotating piston 4 and seal holder ring 6 disappears, water in water pipe enters in interior push pipe 2 and in top cover seat 1, then ejection fire extinguishing, in addition, the water entering in interior push pipe 2 also enters in extension tube attached 3 from offering limbers 9, then enters in top cover seat 1 from the inlet opening 13 of top cover seat 1, and then ejection has ensured the enough of water spray, guarantees the validity of sprinkling fire.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
