Description

Sprinkler head {Sprinkler head}

The present invention relates to a sprinkler head, and more specifically, to form a thermal portion in the deflector inner space, the thermal portion fuse more securely from the external impact that may be generated during distribution, installation and use and other impacts during non-fire. The present invention relates to a sprinkler head that protects, senses ambient heat more quickly by a heat collecting plate and a deflector vent in case of a fire, and enables a quick and accurate fire suppression due to a precise combination of a closed disk and a deflector.

In general, sprinkler heads are installed in buildings larger than a certain size for initial fire suppression. The sprinkler head is divided into the installation place or the purpose of use according to the shape, and is classified into the glass bulb type and the lead type according to the thermal element used.

Sprinkler heads strictly limit the installation specifications and performance according to the height of the ceiling and the surrounding environment. Even if the specification and performance test are satisfied, the sprinkler head is not exposed to the thermal element (glass bulb or melt fuse) from external shock during distribution or installation. Means of protection are inadequate, resulting in malfunctions.

1 to 3 are embodiments of the sprinkler head according to the prior art. First, Figure 1 is an embodiment of a flush type sprinkler head disclosed in Republic of Korea Utility Model Registration No. 043464 (2005.12.9. Announcement). In flush type, extinguishing water is sprayed by deflector movement and water jet plate. The problem of the sprinkler head according to FIG. 1 is that the thermal element (glass bulb) is easily damaged by an external impact. The case occurs. That is, in order to detect the heat of the heat sensitive body, the cover surrounding the heat sensitive body should be almost opened to the outside, and due to the open area of the cover, care must be taken to prevent damage during movement, installation, and everyday.

Figure 2 is an embodiment of a circular type sprinkler head disclosed in Korean Patent Laid-Open Publication No. 1999-010327 (published on February 8, 1999). In the circular type, the extinguishing water is injected by the water injection port of the deflector. The problem of the sprinkler head according to FIG. 2 is that the thermal element (low melting point alloy) is easily damaged by an external impact. It happens. That is, although it may be said that the thermal element is wrapped and protected by a cylinder or the like, in order for the thermal element to be thermally sensed, the protective means surrounding the thermal element is limited in thickness and material. Since the deformation is caused by a force of a degree, such sprinkler head should be taken care of to prevent breakage during movement, installation, and everyday.

The frame 10 is coupled to a pipe (not shown) provided in the ceiling of the building, and is coupled to the deflector screw 57 (see FIG. 5) of the deflector 50 through the frame screw 11. In the space between the frame 10 and the deflector 50, the closed disk 20, the support part 30, and the thermal part 40 are sequentially stacked.

The closing disk 20 blocks the waterproof port 12 of the frame 10 to prevent the discharge of the extinguishing water normally. Looking at one embodiment of the coupling between the frame 10 and the closed disk 20 in detail, the packing 21 is attached to the packing groove 22 of the closed disk 20, the frame groove of the frame 10 To (13). The closed disk column 23 of the closed disk 20 is caught by the locking jaw 56 (see FIG. 5) of the deflector 50 when the fuse of the heat-sensitive portion 40 is melted in a fire. Fire extinguishing water discharged from 12) is discharged to the water injection port 52 of the deflector 50 without being discharged to the vent port 54 of the deflector 50.

The support part 30 supports the closed disc 20 at the upper part and is positioned above the heat sensitive part 40. When the fuse of the heat sensitive part 40 is melted in a fire, the support part 30 closes the closed disc 20 which blocks the waterproof path 12. It is to be quickly caught on the locking jaw (56). Looking at the specific embodiment in more detail, by providing a spring 32 between the pillar nut 31 for supporting the lower portion of the closed disk 20 and the packing washer 33 provided on the thermal portion 40, As soon as the fuse 41 is melted, the packing washer 33 is pushed by the elastic force (restoration force) of the spring 32, and the spring 32 is supported as the spring 32 is extended. The pillar nut 31 is used so that the closed disk 20 which is blocking the waterproof path 12 is caught by the locking jaw 56 and the extinguishing water is discharged. The spring 32 may be made of stainless steel or the like, and the restoring force (elastic force) of the spring 32 is almost permanent. The shape of the spring 32 may be configured in various ways, represented by a straight spring 32 in one embodiment of the present specification.

The heat sensing unit 40 detects heat quickly in a fire. Looking at the specific embodiment in more detail, the fuse 41 is inserted into the heat collecting plate groove 43 provided in the heat collecting plate 42. The heat collecting plate 42 protects the fuse 41, and the heat sensing unit 40 is double protected from external shock in the space between the frame 10 and the deflector 50. That is, the heat sensing by the wide protrusion provided in the heat collecting plate 42 and the easy access to the ambient temperature by the vent hole 54 of the deflector 50 eventually result in not only rapid heat sensing but also the heat-sensitive portion 40 from external impact. It may be the best configuration for protection.

In addition, during the movement of the sprinkler head, during installation and during normal operation, not only external shock but also heat condensation on a part of the light (partial concentration of direct sunlight, disposable lighter mischief of children, hereinafter referred to as "partial heat concentration phenomenon") and fire You should be able to work with hours. While the thermal elements exposed to the outside of the conventional deflector 50 are easily deformed or broken by the partial partial heat condensation, the sprinkler head according to the embodiment of the present invention prevents deformation and breakage due to the partial heat condensation. It can prevent. That is, since the fuse 41 is double-protected, the fuse 41 does not react to any partial heat concentration phenomenon, while the ambient temperature rises on average during a fire, so that the fuse 41 is protected by the deflector 50 and the heat collecting plate 42. In the midst of this, it is possible to quickly extinguish the fire in response to the ambient temperature.

In addition, the packing washer 33 is provided with a packing washer 33 of the support part 30 and a heat insulating washer 58 of the deflector 50 as a means for preventing partial heat concentration of the heat sensing part 40. The spring 32 is made of a material that is not easy to heat transfer, heat insulating washer 58 may also be made of a material that is not easy to heat transfer. That is, the packing washer 33 may be made of a slow heat transfer material, such as stainless material, and the insulating washer 58 may be made of a slow heat transfer material, such as asbestos, polycarbon. The configuration of the packing washer 33 and the deflector 50 can increase the heat sensing function of the heat sensing unit 40, the heat detected by the heat collecting plate 42 is surrounding (support 30 and deflector 50) ), Specifically, the packing washer 33 and the insulation washer 58 to prevent the transfer to the fuse 41 to be concentrated.

The deflector 50 functions to effectively discharge the extinguishing water ejected from the waterproof port 12 of the frame 10. Looking at an embodiment of the coupling relationship of the deflector 50 in more detail, the heat-insulating washer 58 is made of a relatively slow heat transfer material so that the heat detection of the heat-sensitive portion is concentrated; A bolt 51 supporting the closed disk 20, the support part 30, the heat-sensitive part 40, and the heat-insulating washer 58 and engaged with the nut 55 under the deflector 50; A vent hole 53 and a vent hole 54 provided below the deflector 50 to facilitate inflow of external air so that heat sensing of the heat sensing part 40 can be concentrated; When the fuse 41 is melted and the closed disk 20 is opened, the closed disk 20 is guided correctly by guiding the closed disk column 23 so that the fire extinguishing water of the waterproof passage 12 hits the upper portion of the closed disk 20. And a water injection port 52 for inducing extinguishing water jet.
