Description
Technical Field
The utility model relates to a equipment technical field, especially an adjustable fan-shaped shower nozzle spray.
Background
In order to prevent a serious fire accident that a group is killed and injured in a bus compartment, a bus compartment with a higher protection grade needs to be provided with a fixed fire extinguishing system for a bus passenger compartment. Usually, the spray head of the fixed fire extinguishing system for the passenger cabin of the bus is arranged at the top of the carriage, 200 kilograms of fire extinguishing agent is needed to meet the fire extinguishing requirement of a 12-meter fire model of GA1264-2015 fixed fire extinguishing system for the passenger cabin of the bus, and if the fan-shaped spray head is used for releasing the fire extinguishing agent under the seat of the carriage, the same fire extinguishing effect can be achieved by using 1/10 fire extinguishing agent. By adjusting the angle of the sector, the coverage area of the fire extinguishing agent on the carriage floor can be increased, and the fire extinguishing efficiency is improved. The adjustable fan-shaped spray head can reduce the occupied space of the fire extinguishing system and improve the carrying capacity of the bus; the dead weight of the bus is reduced, and the running cost is reduced.
Disclosure of Invention
The utility model aims to solve the technical problem of increasing the coverage area of the fire extinguishing agent.
In order to solve the technical problem, the utility model relates to an adjustable fan-shaped spray head, which comprises a nozzle body, a nozzle and a locking nut, wherein the nozzle body is L-shaped; the method is characterized in that: the nozzle body right side counter bore interface is pegged graft and is had the nozzle, the nozzle output is opened has "V" type groove, the limit of falling down that nozzle waist remained is with lock nut joint, lock nut and the adjusting thread on the nozzle body right side counter bore interface outer wall connect soon.
Furthermore, the opening angle of the V-shaped groove is 25-35 degrees.
Furthermore, the top end of a water inlet hole at the tail end of the V-shaped groove is hemispherical, and the water inlet hole is communicated with the V-shaped groove.
Furthermore, a fixed thread is reserved on the outer side of the threaded joint at the bottom of the nozzle body and is screwed with an output port of the fire extinguishing device.
After the structure is adopted, the utility model discloses an adjustable fan-shaped spray head, which adopts a nozzle structure with a V-shaped groove at the output end, and the fire extinguishing agent is released in a fan shape; the angle of the V-shaped groove of the nozzle can be adjusted by loosening the locking nut, so that the coverage area of the fire extinguishing agent is increased; the technical problem of nozzle sealing is solved through the structure of preventing the nozzle from chamfering.

Detailed Description
As shown in fig. 1, 2, 3, 4 and 5, an adjustable sector sprinkler includes a nozzle body, a nozzle and a locking nut, wherein the nozzle body is in an "L" shape; the method is characterized in that: the nozzle body 1 is inserted with the nozzle 3 through the right-side counter bore interface 1-1, the output end of the nozzle 3 is provided with a V-shaped groove 3-1, the anti-falling edge 3-2 reserved at the waist of the nozzle 3 is clamped with the locking nut 2, and the locking nut 2 is screwed with the adjusting thread 1-2 on the outer wall of the right-side counter bore interface 1-1 of the nozzle body 1. Wherein, operating personnel will be at the in-process of installation extinguishing device, can be according to the position and the angle modulation nozzle 3 of extinguishing device installation to increase and spray coverage area, improve fire extinguishing efficiency. In the releasing process of the fire extinguishing agent, the fire extinguishing agent enters a pipeline inside the nozzle body 1 along the threaded joint 4; under the driving of pressure, the fire extinguishing agent is sprayed out through the nozzle 3, and the release of the fire extinguishing agent is completed. During the release process of the fire extinguishing agent, the phenomenon that the spraying pressure is reduced due to pipeline leakage can occur; therefore, the sealing measures for the pipes also need to be perfected. In order to prevent the problems, the utility model discloses a structure that the nozzle was prevented falling limit, will nozzle 3 pegs graft earlier in nozzle body 1 right side counter bore interface 1-1, utilizes adjusting screw 1-2 and lock nut 2 to connect soon and lock.
As shown in FIG. 5, the opening angle of the V-shaped groove 3-1 is 25-35 degrees. Wherein, the opening angle of 25-35 degrees can be made according to different scenes to adjust the jet distance and the coverage area.
As shown in figures 1, 2 and 4, a fixed thread 4-1 is left outside a threaded connector 4 at the bottom of the nozzle body 1, and the fixed thread 4-1 is screwed with an output port of the fire extinguishing device. In order to improve the sealing performance of the threaded joint 4 at the bottom of the nozzle body 1, the outer side of the threaded joint 4 is provided with a fixed thread 4-1, and the fixed thread 4-1 is screwed with an output port of the fire extinguishing device.
As shown in figures 1 and 5, the top end of a water inlet hole at the tail end of the V-shaped groove 3-1 is hemispherical, and the water inlet hole is communicated with the V-shaped groove 3-1. Wherein, the hemispherical inlet opening can increase the injection pressure.
Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many changes and modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
