Description
Technical field
The invention belongs to fire-fighting equipment field, is related to a kind of fire extinguishing sprayer automated toed respond to.
Background technology
Fire extinguishing sprayer traditional at present has two kinds：One kind is glass alveolitoid shower nozzle, and one kind is fusible link shower nozzle.Work as fire
During generation, glass envelope blast or fusible metal melt, and extinguishing chemical sprays, and realize fire extinguishing.Traditional fire extinguishing sprayer responds accurate
Property is poor, and sensitivity is relatively low.Moreover, glass envelope and fusible metal are all disposable products, fire extinguishing sprayer oneself can only be realized
It is dynamic to open, the automatic closing of shower nozzle can not be realized.
The content of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, there is provided one kind automated tos respond to fire extinguishing sprayer, and this is automatic
Respond fire extinguishing sprayer and glass envelope or fusible metal element are substituted using shape memory metal so that temperature-sensitive element is by disposable elements
It is changed into being recycled for multiple times, while can be realized and opened and closed automatically according to the temperature of working site, simple in construction, sensitivity
It is high.
In order to solve the above-mentioned technical problem, the present invention is achieved through the following technical solutions：
One kind automated tos respond to fire extinguishing sprayer, including nozzle body 1, inner support 2, sealing ring 3, push rod 4, support frame 5, spiral shell
Nail 6, splash box 7, top cover 8, fixed cover 9, memorial alloy plate 10, water plug 11, slit 12, at the upper end A of nozzle body 1 and under
End B places carry external screw thread, and the screw thread at the upper end A of nozzle body 1 spins with feed pipe, the screw thread at the lower end B of nozzle body 1 and
Support frame 5 spins；At the upper end C of inner support 2 and lower end D places carry external screw thread, screw thread at the upper end C of inner support 2 and
Nozzle body 1 spins, and the screw thread at the lower end D of inner support 2 spins with fixed cover 9；The outer ring of the sealing ring 3 is fixed on inner support
2 inner sides；The memorial alloy plate 10 is made using Nitinol, in disk form at normal temperatures, at high temperature concave sphere, note
Recall alloy sheets 10 to be arranged between fixed cover 9 and the lower end of inner support 2；The water plug 11 is in circular platform type, and upper round platform is embedded in sealing ring 3
Inner ring, lower round platform bottom belt is fluted；The lower end of the push rod 4 is fixed on memorial alloy plate 10, and upper end is fixed on water plug
In the groove of 11 times round platforms；The bottom of support frame 5 is provided with circular hole；The top cover 8 and splash box 7 pass through screw 6 and support
Framework 5 is linked.
The slit 12 is distributed in the circumference of splash box 7 along the angle with α, and α angular ranges are recommended between 20 ° and 50 °
Angle is 35 °.
The beneficial effects of the present invention are：The present invention provides a kind of autoamtic fire extinguishing jet head, using marmem as quick
Sensing unit, when the external world reaches the temperature of setting, it can be achieved to automatically turn on and close, heat-sensitive element can be with Reusability, simultaneously
It responds temperature and can set and adjust within the specific limits, meets the needs of different fire-extinguishing applications.

Embodiment
One kind automated tos respond to fire extinguishing sprayer, including nozzle body 1, inner support 2, sealing ring 3, push rod 4, support frame 5, spiral shell
Nail 6, splash box 7, top cover 8, fixed cover 9, memorial alloy plate 10, water plug 11, slit 12, at the upper end A of nozzle body 1 and under
End B places carry external screw thread, and the screw thread at the upper end A of nozzle body 1 spins with feed pipe, the screw thread at the lower end B of nozzle body 1 and
Support frame 5 spins；At the upper end C of inner support 2 and lower end D places carry external screw thread, screw thread at the upper end C of inner support 2 and
Nozzle body 1 spins, and the screw thread at the lower end D of inner support 2 spins with fixed cover 9；The outer ring of the sealing ring 3 is fixed on inner support
2 inner sides；The memorial alloy plate 10 is in disk form, and memorial alloy plate 10 is arranged between fixed cover 9 and the lower end of inner support 2；Institute
It is in circular platform type to state water plug 11, and upper round platform is embedded in the inner ring of sealing ring 3, and lower round platform bottom belt is fluted；The lower end of the push rod 4 is consolidated
It is scheduled on memorial alloy plate 10, upper end is fixed in the groove of 11 times round platforms of water plug；The bottom of support frame 5 is provided with circular hole；
The top cover 8 and splash box 7 are linked by screw 6 and support frame 5.
The slit 12 is distributed in the circumference of splash box 7 along the angle with α, and α angular ranges are recommended between 20 ° and 50 °
