Description

Technical Field

[0001] The utility model relates to the field of sprinkler head structures, in particular to a safe and efficient glass ball self-spraying sprinkler head. Background Art

[0002] The traditional glass ball self-spraying water sprinkler is an automatic fire extinguishing device designed based on a simple principle. Its overall principle involves multiple links such as fire detection, sprinkler start-up, spraying process and water supply. The details are as follows: There is usually a risk of fire in the place where the sprinkler is installed, so thermistors or temperature sensors are installed on the sprinkler. These elements can sense changes in ambient temperature. Once the ambient temperature rises to a certain level and reaches or exceeds the preset trigger point, the thermistor will be triggered. Once the thermistor is triggered, it will start the spraying mechanism of the sprinkler. A glass ball is usually installed on the top of the head. When the sprinkler is started, the glass ball will break instantly. After the glass ball breaks, it is driven by pressure and the fire extinguishing agent in the pipe system connected to the sprinkler flows out. The fire extinguishing agent will be sprayed to the source of the fire through the sprinkler to form water mist or water flow to extinguish the fire or prevent the fire from spreading. The sprinkler is connected to a pre-arranged pipe system in a building or other facility. These pipe systems are usually connected to a water source or fire extinguishing agent storage equipment, such as a water tank or a fire water pipe network. This ensures that the sprinkler can quickly obtain the required fire extinguishing medium when a fire occurs.

[0035] Example

[0036] like Figure 1 As shown, the embodiment of the utility model provides a safe and efficient glass ball self-spraying water sprinkler, including a yoke arm frame 1 for supporting the internal components of the sprinkler, the yoke arm frame 1 includes a connecting end 2 and a spraying end 3, the connecting end 2 is used to connect to a storage device for a fire extinguishing agent, where the fire extinguishing agent can be water, carbon dioxide, etc., the spraying end 3 is provided with a splash plate 4, the splash plate 4 is provided with a plurality of splash holes, the splash plate 4 is used to disperse the water flow into fine water droplets to achieve a wider spraying effect, the connecting end 2 is provided with a connecting port 6 and a nozzle valve body 5, the connecting port 6 is used to connect to a water supply system or other fire extinguishing agent supply system, the nozzle valve body 5 is arranged on the inner side of the connecting port 6, and the connecting port 6 can be blocked to prevent the fire extinguishing agent or the fire extinguishing agent from passing through before the sprinkler is activated, and the nozzle valve body 5 is provided with a glass ball 7 The glass ball 7 is arranged in the yoke arm frame 1 and connected to the yoke arm frame 1. The glass ball 7 is connected to the yoke arm frame 1 as an activation element of the sprinkler head. It can not only be stably arranged in the yoke arm frame 1, but also support the sprinkler head valve body 5. The glass ball 7 is arranged on the yoke arm frame 1, and the yoke arm frame 1 can protect the glass ball 7 to prevent the glass ball 7 from being damaged due to collision during transportation; when the glass ball 7 explodes due to heat, the sprinkler head valve body 5 can fall along the spraying end 3 of the yoke arm frame 1, and the blockage of the connecting port 6 is released; when the fire extinguishing agent is sprayed out from the connecting port 6, it can fall into the splash plate 4 and spray outward. The splash plate 4 is arranged on the inner side of the yoke arm frame 1, so that the splash plate 4 will not be applied when the sprinkler head is placed in any direction, thereby achieving the effect that the splash plate 4 will not be tilted or deformed due to external collision. At the same time, the splash plate 4 is arranged inside the yoke arm frame 1, which solves the problem of the yoke arm frame 1 and the yoke arm ring 10 blocking the water flow when the water flows from the connection port 6 to the splash plate 4, and achieves the effect of reducing the system head loss and making the sprinkler spray more uniform. Of course, in order to improve the installation sealing, stability and flexibility of the sprinkler, a connecting internal thread can be arranged inside the connection port 6.

[0037] For ease of understanding, in the embodiments of the present invention, the fire extinguishing agent is described as water. In other embodiments, the type of fire extinguishing agent is not limited. Before the sprinkler head provided in the embodiment of the present invention is activated, the glass ball 7 is arranged inside the yoke arm frame 1 and supports the sprinkler valve body 5. At this time, the sprinkler valve body 5 can block the connecting port 6 to prevent water from spraying. When the sprinkler head of the embodiment of the present invention needs to be activated, it is only necessary to heat the glass ball 7. The glass ball 7 will explode due to thermal expansion, and the fragments will fall directly through the gap of the yoke arm frame 1. Since the support of the sprinkler valve body 5 by the glass ball 7 is released, the sprinkler valve body 5 will also fall through the gap of the yoke arm frame 1, thereby releasing the blockage of the connecting port 6. In this way, water with a certain pressure will enter the splash plate 4 from the connecting port 6, diffuse through the splash plate 4 and then spray outward, thereby achieving the purpose of rapid fire extinguishing. In the embodiment of the utility model, since the glass ball 7 and the splash plate 4 are arranged in the yoke arm frame 1, there will be no problem of applying force to the splash plate 4 and the glass ball 7 when the nozzle is placed in any direction. When the nozzle collides, it will not directly collide with the splash plate 4 and the glass ball 7. The yoke arm frame 1 protects the splash plate 4 and the glass ball 7 while ensuring that the splash plate 4 can spray water out smoothly, thereby improving the stability of the nozzle.

[0038] Specifically, the yoke arm frame 1 includes an axial portion 8 and a transverse portion 9. The transverse portion 9 is arranged at the end of the spraying end 3 and fixed by the axial portion 8. The splash plate 4 is arranged on the inner side of the transverse portion 9. The connection between the transverse portion 9 and the axial portion 8 can be an integral arrangement or can be connected by bonding, clamping, etc., as long as the purpose of stable connection can be achieved. The splash plate 4 is arranged on the inner side of the transverse portion 9. This structure makes the splash plate 4 under the protection of the transverse portion 9, and at the same time facilitates the water flow to spray through the splash holes on the splash plate 4. When the fire extinguishing agent flows in from the connection port 6, it will directly enter the inner side of the transverse portion 9, and then dispersed into fine water droplets through the splash holes on the splash plate 4 to achieve uniform spraying. This structure enhances the structural stability of the entire sprinkler head, because the transverse portion 9 can serve as a supporting structure to protect the splash plate 4 from external impact. As a preferred embodiment of the utility model, a yoke arm ring 10 is provided on the transverse portion 9, and the splash plate 4 is provided on the yoke arm ring 10, and there is a gap 11 between the yoke arm ring 10 and the transverse portion 9. The yoke arm ring 10 fixes or supports the splash plate 4, and the splash plate 4 is not directly fixed on the transverse portion 9, but is installed on the yoke arm ring 10. This structure provides additional stability and facilitates the installation and maintenance of the splash plate 4. Of course, in other embodiments, the splash plate 4 can also be directly provided on the transverse portion 9, which is not limited here. Back to the embodiment of the utility model, when the temperature changes, the splash plate 4 material and the transverse portion 9 material may expand or contract, and the gap 11 provides the necessary space to avoid structural deformation or damage caused by thermal expansion.

[0039] Furthermore, a bolt 12 hole is provided on the yoke arm ring 10, and a bolt 12 is passed through the bolt 12 hole. One end of the bolt 12 is located outside the transverse portion 9, and the other end is in contact with the glass ball 7. It should be noted that the contact here can be a movable release or a fixed connection, which is not limited here. The bolt 12 is used to contact the external high-temperature environment, so as to quickly transfer the external temperature to the glass ball 7. A heat transfer copper wire 13 is provided inside the glass ball 7. The bolt 12 and the heat transfer copper wire 13 can be in direct contact or through the glass ball 7. The part of the bolt 12 outside the transverse portion 9 can transfer heat to the heat transfer copper wire 13. Specifically, when a fire occurs, one end of the bolt 12 exposed to the transverse portion 9 is heated and transfers the heat to the heat transfer copper wire 13 inside the glass ball 7 through the entire bolt 12. The heating of the copper wire will accelerate the increase in the temperature of the liquid inside the glass ball 7, so that the glass ball 7 will explode more quickly and accurately, solving the problem that the nozzle in the prior art relies solely on the glass ball 7 to sense the change in the external environmental temperature, and achieving the effect of more rapid and accurate operation of the thermal sensitive element. It should be noted that the structure enables the glass ball 7 to be stably mounted in the yoke arm frame 1 through the bolt 12, and the glass ball 7 stably supports the nozzle valve body 5. The structure ensures the stability of the nozzle in the unactivated state, and can respond quickly when activated, providing effective fire extinguishing protection. Preferably, the bolt 12 is made of copper, because copper is a material with excellent thermal conductivity, and its thermal conductivity is higher than many other metals. Therefore, the use of copper bolts 12 can ensure that heat is quickly transferred from the transverse portion 9 to the heat transfer copper wire 13 in the glass ball 7, thereby heating the glass ball 7 and accelerating the activation speed of the nozzle.

[0040] In order to ensure that the yoke arm frame 1 does not block the falling of debris of the exploded glass ball 7 or the falling of the nozzle valve body 5, the embodiment of the utility model provides a preferred yoke arm frame 1 structure, specifically, the axial portion 8 includes a plurality of yoke arm support rods 14, wherein each yoke arm support rod 14 is connected to the transverse portion 9, that is, the connection between the plurality of yoke arm support rods 14 and the transverse portion 9 provides a stable structural frame, and there is a pure gap 11 between each yoke arm support rod 14, so that the yoke arm support rod 14 can not only protect the glass ball 7 and other components, but also ensure the smooth falling of the debris of the glass ball 7 or the nozzle valve body 5. Exemplarily, three yoke arm support rods 14 are provided, and the separation angle between every two yoke arm support rods 14 is 120°. The three yoke arm support rods 14 evenly disperse the forces acting on the transverse portion 9 and the splash plate 4, reduce the stress of a single support rod, improve the durability and reliability of the overall structure, and at the same time ensure the size of the gap between two adjacent yoke arm support rods 14. Of course, in other embodiments, four yoke arm support rods 14, five yoke arm support rods 14, etc. may also be provided, which is not limited here.

[0041] In order to improve the sealing effect of the nozzle valve body 5 on the connection port 6, a yoke arm seat 15 can be fixedly connected to the axial portion 8, the connection port 6 is connected to the yoke arm seat 15, a through hole 16 is arranged in the yoke arm seat 15, the through hole 16 is communicated with the connection port 6, and the nozzle valve body 5 is arranged on the inner wall of the through hole 16 and can block the through hole 16. That is, the yoke arm seat 15 stably supports the nozzle valve body 5, and the two cooperate to achieve the sealing of the connection port 6. Further, a boss 17 is arranged on the side of the through hole 16 facing the connection port 6, and the boss 17 can limit the movement of the nozzle valve body 5 toward the side of the connection port 6. The setting of the boss 17 can make the nozzle valve body 5 fit with the yoke arm seat 15 under the support of the glass ball 7, generate pressure between each other, ensure the sealing between the nozzle valve body 5 and the yoke arm seat 15, and improve the sealing of the nozzle valve body 5 to the connection port 6. Preferably, in order to ensure the supporting stability of the glass ball 7 on the nozzle valve body 5, the glass ball 7 and the nozzle valve body 5 can be arranged to be connected by a fixing rivet 18. When the glass ball 7 explodes, the nozzle valve body 5 and the fixing rivet 18 fall together, and the yoke arm seat 15 is fixedly connected to the connecting port 6. Water will flow from the connecting port 6 into the through hole 16, and then flow from the through hole 16 to the splash plate 4.

For those skilled in the art, the utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the utility model omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the utility model.
