Technical Field
[0001] The utility model belongs to the technical field of fire sprinkler heads, and in particular relates to a sprinkler head with temperature early warning. Background Art
[0002] Industrial fire extinguishing equipment is installed on the ceiling of offices, factories, etc. When the surrounding temperature reaches a certain temperature due to the heat of the fire, the water sprinkler head uses a heat-sensitive component to open the water outlet and spray water to extinguish the fire. However, some sprinkler heads will spray water even when there is no fire, making it impossible to determine whether it is due to environmental factors that cause the sprinkler head to malfunction or a defect in the sprinkler head itself. Utility Model Content
[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a sprinkler nozzle with temperature warning, which can make corresponding processing according to the change of color, and determine whether the misoperation of the sprinkler nozzle is caused by environmental factors or defects of the sprinkler nozzle itself, thereby avoiding losses caused by misoperation of the sprinkler nozzle.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a sprinkler head with temperature warning, including a water outlet connecting seat, a sealing element, a mounting seat and a glass ball, the water outlet connecting seat is connected and installed with a fire water pipe, the sealing element is sealed on the output port of the water outlet connecting seat, the mounting seat is installed on the water outlet connecting seat, the glass ball is installed in the mounting seat and is arranged to abut against the bottom of the sealing element, and the glass ball is filled with temperature-changing powder.
[0005] A fixing ring is sleeved on the glass ball, a memory metal wire is connected to the fixing ring, and the other end of the memory metal wire is fixedly connected to the mounting seat.
[0006] The center position of the mounting seat is connected with a placement seat through threads, and the placement seat is provided with a placement groove for accommodating the bottom of the glass ball.
[0007] A knob is installed below the placement seat, and an outer surface of the knob is provided with anti-slip grooves.
[0008] A rubber pad is placed in the placement groove.
[0009] A water receiving tray is installed below the mounting seat.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The utility model discloses a sprinkler nozzle with temperature warning. The glass ball is filled with temperature-changing powder. Corresponding processing is performed in advance through color change to avoid losses caused by misoperation of the sprinkler nozzle. The action reasons of the sprinkler nozzle are recorded to avoid the situation in which, after the sprinkler nozzle misoperates, it is impossible to determine whether the misoperation of the sprinkler nozzle is caused by environmental factors or defects of the sprinkler nozzle itself.

[0016] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.
[0017] like Figure 1-Figure 3 As shown, this embodiment provides a sprinkler with temperature warning, including a water outlet connection seat 1, a sealing element 2, a mounting seat 3 and a glass ball 4. The water outlet connection seat 1 is connected and installed with a fire water pipe, the sealing element 2 is sealed and placed on the output port of the water outlet connection seat 1, the mounting seat 3 is installed on the water outlet connection seat 1, the glass ball 4 is installed in the mounting seat 3 and is arranged to abut against the bottom of the sealing element 2, and the glass ball 4 is filled with temperature-changing powder 5. Specifically, the temperature-changing powder 5 changes the molecular structure of the organic matter due to electron transfer at a specific temperature, thereby achieving color change. The glass ball 4 is filled with temperature-changing powder 5, and corresponding treatment is made in advance through color changes to avoid losses caused by misoperation of the sprinkler, and the cause of the action of the sprinkler is recorded to avoid the failure to determine whether the misoperation of the sprinkler is caused by environmental factors or defects of the sprinkler itself after the sprinkler sprays by mistake.
[0018] Furthermore, the mounting seat 3 is provided with a guide rod 6 for the sealing element 2 to move up and down, and guide rings 7 are provided on both sides of the sealing element 2 to slide with the guide rod 6. When the sealing element 2 falls, it can move downward along the guide rod 6 and be placed on the mounting seat 3, thereby preventing the sealing element 2 from being lost.
[0019] Furthermore, a fixing ring 7 is sleeved on the glass ball 4, and a memory metal wire 8 is connected to the fixing ring 7, and the other end of the memory metal wire 8 is fixedly connected to the mounting seat 3. Specifically, the memory metal wire 8 is made of nickel-titanium alloy, which is a martensitic phase change alloy with a very regular atomic arrangement and a volume change of less than 0.5%. This alloy will deform under the action of external force, and can restore its original shape under certain temperature conditions, with a recovery function of more than one million times. It is a prior art material. In the event of a fire, the glass ball 4 is only partially broken or leaks due to quality problems, and is still supported under the sealing element 2, so that water cannot come out. The memory metal wire 8 can recover and shrink due to heat to pull the fixing ring 7 to drive the glass ball 4 out of the sealing element 2, so that the water can push the sealing element 2 away to extinguish the fire.
[0020] Furthermore, the center of the mounting seat 3 is connected with a placement seat 13 through a thread, and the placement seat 13 is provided with a placement groove 14 for accommodating the bottom of the glass ball 4. Specifically, a knob is installed below the placement seat 13, and the outer surface of the knob is provided with anti-slip grooves for easy rotation. A rubber pad is placed in the placement groove 14 to play a buffering effect. When installing a new glass ball 4 after the sprinkler head has finished spraying water, the glass ball 4 can be directly placed in the placement groove 14, and then the placement seat 13 is tightened. When the placement seat 13 is tightened, the glass ball 4 rises to hit the sealing element 2 and rises to block the output port of the water outlet connection seat 1, so as to achieve convenient installation.
[0021] Further, a water receiving tray 15 is installed below the mounting seat 3. The water flow impacts the water receiving tray 15 to form water sprays that spread out.
[0022] The above shows and describes the basic principles and main features of the invention and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the invention, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be defined by the attached claims and their equivalents.
