Description

Technical Field

[0001] The present application relates to the field of fire sprinkler heads, and in particular to a fire sprinkler head. Background Art

[0002] In modern industrial, civil and commercial projects, a large number of fire-fighting facilities are installed and used, including fire boxes, fire hydrants, fire sprinkler heads, etc. Fire boxes and fire hydrants are made of metal, while fire sprinkler heads have glass cylinders with applicable temperatures of (4-70 degrees). The glass cylinders are filled with organic solutions with different expansion coefficients. After thermal expansion at different temperatures, the glass cylinders burst, and high-pressure water flows along the splash plate to the fire point. Due to the special nature of their functions, the application of fire sprinkler heads is much wider than that of fire boxes and fire hydrants. If the fire sprinkler head does not have finished product protection measures, the sprinkler head will be contaminated by paint or coatings, or the glass ball will be damaged by collision during construction. The contamination of the sprinkler head will cause the glass ball to fail to burst in time when encountering a fire or fail to spray water normally after bursting, and the normal protection range of the sprinkler head will not be reached. Utility Model Content

[0003] In order to solve the problem that fire sprinkler heads have no finished protection measures, or glass balls are damaged by collisions during construction, and the sprinkler heads are contaminated, which will cause the glass balls to fail to explode in time when encountering a fire or fail to spray water normally after explosion, and the normal protection range of the sprinkler heads cannot be reached, the present application provides a fire sprinkler head.

[0004] The fire sprinkler head provided in this application adopts the following technical solution:

[0005] A fire sprinkler head comprises a threaded head, a branch pipe is provided on the bottom surface of the threaded head, a U-shaped tube is connected to the bottom surface of the branch pipe, sprinkler heads are provided at both ends of the bottom surface of the U-shaped tube, the sprinkler head comprises a mounting seat, a protective component is provided on the outer sleeve of the mounting seat, and the protective component comprises an upper mounting ring.

[0006] Preferably, the upper mounting ring is sleeved on the outer wall of the mounting seat, a lower mounting ring is provided directly below the upper mounting ring, and a mesh cover is provided between the lower mounting ring and the upper mounting ring.

[0007] Preferably, a support plate is provided inside the lower mounting ring, and two support plates are provided and are arranged in a left-right symmetrical shape, the top surfaces of the two support plates are connected to the mounting seat, and the bottom surfaces of the two support plates are connected to the base.

[0008] Preferably, a sprinkler is provided on the bottom surface of the base, a nozzle is provided on the bottom surface of the mounting seat, and a glass bulb is provided between the nozzle and the base.

[0009] Preferably, the two mounting seats are threadedly connected to both ends of the bottom surface of the U-shaped tube.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. The upper mounting ring, mesh cover and lower mounting ring can be installed on the outside of the sprinkler head by screws. The structure is simple and easy to disassemble and replace later. The setting of the mesh cover can protect the sprinkler head inside the mesh cover to prevent the sprinkler head from being damaged due to some external force collision, thereby affecting the use of the device;

[0012] 2. The glass bulb is filled with liquid with a high expansion coefficient. When the ambient temperature rises, the liquid begins to expand. When it expands to a certain extent, the glass bulb cannot withstand it and breaks. Unobstructed water sprays out from the nozzle. The water hits the sprinkler and is continuously splashed, thereby expanding the spraying range. Different expansion liquids can be filled in the glass bulb to achieve the spraying threshold requirements of different scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The present application embodiment discloses a fire sprinkler head, referring to Figure 1-Figure 2, including a threaded head 1, a branch pipe 2 is fixedly arranged on the bottom surface of the threaded head 1, a U-shaped tube 3 is fixedly connected to the bottom surface of the branch pipe 2, a sprinkler head 4 is arranged at both ends of the bottom surface of the U-shaped tube 3, and the sprinkler head 4 includes a mounting seat 8, the threaded head 1, the branch pipe 2, the U-shaped tube 3 and the mounting seat 8 are interconnected, the threaded head 1 is connected to the water outlet of the fire water pipe, the water valve is opened, and water can enter the branch pipe 2 through the threaded head 1, and is transported to the U-shaped tube 3 by the branch pipe 2, and finally reaches the mounting seat 8, and the outer sleeve of the mounting seat 8 is provided with a protective component, and the protective component includes an upper The mounting ring 5 is a mounting ring 5, wherein the upper mounting ring 5 is detachably sleeved on the outer wall of the mounting seat 8 by means of screws. A lower mounting ring 7 is provided directly below the upper mounting ring 5. A mesh cover 6 is fixedly provided between the lower mounting ring 7 and the upper mounting ring 5. The upper mounting ring 5, the mesh cover 6 and the lower mounting ring 7 can be mounted on the outside of the shower head 4 by means of screws. The structure is simple and it is convenient to disassemble and replace it later. Moreover, the provision of the mesh cover 6 can protect the shower head 4 in the mesh cover 6 to prevent the shower head 4 from being damaged due to some external force collision, thereby affecting the use of the device.

[0019] Reference Figure 3 A support plate 13 is movably provided inside the lower mounting ring 7. There are two support plates 13, which are symmetrically arranged on the left and right. The top surfaces of the two support plates 13 are fixedly connected to the mounting seat 8. The bottom surfaces of the two support plates 13 are fixedly connected to a base 12. A sprinkler 11 is fixedly provided on the bottom surface of the base 12. A nozzle 9 is fixedly provided on the bottom surface of the mounting seat 8. A glass bulb 10 is fixedly provided between the nozzle 9 and the base 12. The two mounting seats 8 are threadedly connected to the two ends of the bottom surface of the U-shaped tube 3. The glass bulb 10 is filled with a liquid with a high expansion coefficient. When the ambient temperature rises, the liquid begins to expand. When it expands to a certain extent, the glass bulb 10 cannot withstand it and breaks. Unobstructed water is sprayed out from the nozzle 9.

The water hits the sprinkler 11 and is continuously splashed, thereby expanding the spraying range. The upper mounting ring 5, the mesh cover 6 and the lower mounting ring 7 can be mounted on the outside of the sprinkler head 4 by screws. The structure is simple and it is convenient to disassemble and replace it later. The setting of the mesh cover 6 can protect the sprinkler head 4 in the mesh cover 6 to prevent the sprinkler head 4 from being damaged due to some external force collision, thereby affecting the use of the device.
