Description

Technical Field

[0001] The present application relates to the technical field of sealed fire sprinkler head devices for clean rooms, in particular to a novel fire sprinkler head and a clean room using the sprinkler head. Background Art

[0002] Clean rooms are building facilities used in the fields of pharmaceuticals, fine chemicals, medical surgery, etc., and are generally set up in existing factory workshops and hospital rooms. People or items entering the clean room need to comply with relevant regulations and change clothes, wash hands, disinfect or other requirements in the designated areas of the clean room. Clean rooms are generally equipped with disinfectant alcohol, production equipment, special production materials, etc. These equipment and materials are flammable and have the potential to cause fire hazards, so it is particularly important to set up fire protection measures.

[0003] At present, clean rooms are generally built with color steel plates and set up in factory workshops. Traditional fire sprinkler heads are embedded in the ceiling A of the clean room, and the water inlet of the fire sprinkler head is connected to the fire pipe C set up on the ceiling B of the factory workshop. Please refer to Figure 1 - Figure 4 In the prior art, the outer sheath D of the fire sprinkler head is directly embedded in the installation hole opened in the color steel plate ceiling A of the color steel plate room. The sealing end cap E at the lower end of the outer sheath D blocks one end of the outer sheath, which plays a hiding effect on the main body F of the fire sprinkler head. The main body F of the fire sprinkler head extends from the other end of the outer sheath D into the inner cavity of the outer sheath D. When the room temperature exceeds 70°C, the low melting point welding metal of the sealing end cap E melts and falls off due to heat, and the main body F of the fire sprinkler head sprays high-pressure water to spray fire extinguishing water into the clean room. Since the installation construction is manually installed, there will be a certain gap between the outer wall of the outer sheath D and the installation hole, so there is a possibility that external dust will enter the clean room through the outer wall of the outer sheath D and the installation hole, affecting the clean environment in the clean room. In addition, the sprinkler head is installed on the fire water pipe, which is a rigid connection. When someone walks on the roof, the color steel plate will produce local downward pressure deformation, and some installed sprinkler head end caps will loosen or fall off, which will have an adverse effect on the clean room.

[0004] Therefore, a new type of fire sprinkler head is urgently needed to avoid affecting the clean environment required by the clean room. Utility Model Content

[0005] The utility model mainly aims at the above problems, proposes a novel fire sprinkler head and a clean room using the sprinkler head, and aims to solve the technical problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides a novel fire sprinkler head and a clean room using the sprinkler head, comprising:

[0007] Fire sprinkler head body;

[0008] A support sleeve, wherein the lower end of the support sleeve is provided with an outward-turned stop ring edge, and the inner wall of the support sleeve is provided with a connecting friction pattern; the outer wall of the upper end of the support sleeve is provided with an external thread; the fire sprinkler head body extends into the support sleeve through the upper end opening of the support sleeve;

[0009] A sealing end cover, the sealing end cover comprises a cover body and a connecting sleeve extending from one end surface of the cover body; the connecting sleeve extends into the inner cavity of the support sleeve and is connected to the support sleeve; the connecting sleeve is provided with connecting friction patterns corresponding to the connecting friction patterns on the inner wall of the support sleeve;

[0010] A dustproof fastener is provided with an internal thread corresponding to the external thread.

[0011] Furthermore, the connection friction pattern is an annular concave-convex pattern.

[0012] Furthermore, the dustproof fastener is an annular sheet.

[0013] Furthermore, the plane where the end face of the dustproof fastener is located is parallel to the plane where the end face of the stop ring edge is located.

[0014] Furthermore, the cover body surrounds the stop ring edge.

[0015] Furthermore, the dustproof fastener, the supporting sleeve and the cover body enclose the fire sprinkler head body.

[0016] The utility model provides a clean room, comprising a novel fire sprinkler head as described above; further comprising a clean room and a corrugated hose; a mounting hole is provided on the roof top plate of the clean room; the stop ring edge of the supporting sleeve is in contact with the lower end surface of the roof top plate, the dustproof fastener is connected to the upper end of the supporting sleeve, and the dustproof fastener is in contact with the upper end surface of the roof top plate; one end of the corrugated hose is connected to the water inlet joint of the fire sprinkler head body, and the other end is connected to the fire pipe joint.

[0017] Furthermore, the clean room is constructed with color steel plates.

[0018] Compared with the prior art, the utility model provides a new type of fire sprinkler head and a clean room using the sprinkler head. When the new type of fire sprinkler head is connected to the roof top plate, the support sleeve is first pushed from the bottom of the roof top plate into the installation hole, so that the stop ring edge is in contact with the lower end surface of the roof top plate, and the other end of the support sleeve extends out of the upper end surface of the roof top plate, and the dustproof fastener is used to tighten the inner thread and outer thread of the support sleeve. The stop ring edge and the dustproof fastener clamp the roof top plate, which can fully close the gap between the outer wall of the support sleeve and the installation hole, and fully isolate the upper end of the roof top plate from the outside, the installation hole, and the clean room. Finally, the connecting sleeve of the sealing end cover is extended into the inner cavity of the support sleeve and connected to the support sleeve. The fire sprinkler head with such a structure and the clean room using the sprinkler head can solve the disadvantage of the prior art that external dust can enter the clean room through the gap at the connection between the fire sprinkler head and the clean room.

[0032] Please refer to Figure 5 - Fig. 9This embodiment provides a new type of fire sprinkler head and a clean room using the sprinkler head, including:

[0033] Fire sprinkler head body 1;

[0034] A support sleeve 2, wherein the lower end of the support sleeve 2 is provided with an outward-turned stop ring edge 210, and the inner wall of the support sleeve 2 is provided with a connecting friction pattern 220; the outer wall of the upper end of the support sleeve 2 is provided with an external thread 230; the fire sprinkler head body 1 extends into the support sleeve 2 through the upper end opening of the support sleeve 2;

[0035] The sealing end cover 3 comprises a cover body 310 and a connecting sleeve 320 extending from one end surface of the cover body 310; the connecting sleeve 320 extends into the inner cavity of the support sleeve 2 and is connected to the support sleeve 2; the connecting sleeve 320 is provided with a connecting friction pattern 220 corresponding to the connecting friction pattern 220 on the inner wall of the support sleeve 2;

[0036] The dustproof fastener 4 is provided with an internal thread 410 corresponding to the external thread 230 .

[0037] The sealing end cover 3 and the supporting sleeve 2 are connected to each other through their respective connecting friction lines 220. Relying on the friction force, the sealing end cover 3 cannot overcome the friction force and separate from the supporting sleeve 2 by its own gravity without the action of external force, so as to keep the sealing end cover 3 from falling. When a fire occurs, the fire sprinkler head body 1 sprays high-pressure water to impact the sealing end cover 3, overcome the friction force, and can impact the sealing end cover 3 and separate from the supporting sleeve 2.

[0038] Please refer to Figure 8 The connection friction pattern 220 is an annular concave-convex pattern.

[0039] This structure is easy to manufacture and assemble, and can also achieve the friction required for the sealing end cover 3 to remain connected to the supporting sleeve 2 and to be separated by the impact of high-pressure water.

[0040] In some embodiments, the connection friction pattern 220 is a thread with a relatively loose connection tightness. After being impacted by the fire water body, the sealing end cover 3 is directly separated from the supporting sleeve 2 without rotation.

[0041] The connection friction pattern 220 is used to realize the connection relationship between the connection sleeve and the support sleeve by friction. As long as the two have concave and convex patterns by friction, any structure with friction connection is acceptable.

[0042] In order to improve the dustproof sealing effect, the connection between the connecting sleeve and the supporting sleeve can be connected by low melting point welding metal.

[0043] Please refer to Figure 8The dustproof fastener 4 is an annular sheet.

[0044] The dustproof fastener 4 of the annular sheet body and the sheet plate can block the upper opening of the mounting hole to prevent external dust and debris from entering the clean room through the upper opening of the mounting hole and the gap between the support sleeve 2 and the mounting hole.

[0045] Preferably, the plane where the end face of the dustproof fastener 4 is located is parallel to the plane where the end face of the stop ring edge 210 is located.

[0046] Because the end faces of the dustproof fastener 4 and the end faces of the stop ring edge 210 will be in contact with the flat roof top plate 6, they can fully block the upper and lower ports of the mounting hole and the gap between the mounting hole and the supporting sheath 2 to prevent dust from passing through.

[0047] Please refer to Figure 6 and Figure 7 , the cover body 310 surrounds the stop ring edge 210 .

[0048] This design can enhance the simplicity of the fire sprinkler head when installed in a clean room. The cover 310 can provide a good hiding effect for other parts of the fire sprinkler head, making it more beautiful and neat.

[0049] Please refer to Figure 7 The dustproof fastener 4, the supporting sleeve 2 and the cover body 310 enclose the fire sprinkler head body 1.

[0050] When a fire occurs, the fire sprinkler head body 1 sprays high-pressure water to disconnect and separate the sealing end cover 3 from the supporting sleeve 2. The fire sprinkler head body 1 is still enclosed in the enclosed space formed by the dustproof fastener 4 and the supporting sleeve 2 to extinguish the fire below.

[0051] Please refer to Figure 5 - Fig. 9 The utility model also provides a clean room, including a new type of fire sprinkler as described above; also includes a clean room, a corrugated hose 5; the clean room roof top plate 6 is provided with a mounting hole; the stop ring edge 210 of the support sleeve 2 is in contact with the lower end surface of the roof top plate 6, the dustproof fastener 4 is connected to the upper end of the support sleeve 2, and the dustproof fastener 4 is in contact with the upper end surface of the roof top plate 6; one end of the corrugated hose 5 is connected to the water inlet joint of the fire sprinkler head body 1, and the other end is connected to the fire pipe 7 joint.

[0052] When connecting the new type of fire sprinkler head to the roof top plate 6, first push the support sleeve 2 from the bottom of the roof top plate 6 into the installation hole, so that the stop ring edge 210 is in contact with the lower end surface of the roof top plate 6, and the other end of the support sleeve 2 extends out of the upper end surface of the roof top plate 6, and the dustproof fastener 4 is used to tighten the internal thread 410 and the external thread 230 of the support sleeve 2. The stop ring edge 210 and the dustproof fastener 4 clamp the roof top plate 6, which can fully close the gap space between the outer wall of the support sleeve 2 and the installation hole, and fully isolate the outside world at the upper end of the roof top plate 6, the installation hole, and the clean room. Finally, the connecting sleeve 320 of the sealing end cover 3 is extended into the inner cavity of the support sleeve 2 to connect with the support sleeve 2.

[0053] The fire sprinkler head with such a structure and the clean room using the sprinkler head can solve the disadvantage in the prior art that external dust can enter the clean room through the gap at the connection between the fire sprinkler head and the clean room.

[0054] Moreover, the clean room also uses a corrugated hose 5 to connect the fire sprinkler head body 1 with the fire pipe 7 joint, avoiding the traditional clean room using all rigid fire pipes 7 directly connected to the fire sprinkler head body 1.

[0055] In the prior art, there is a gap between the upper end surface of the roof top plate 6 of the clean room and the ceiling of the factory workshop or hospital room. Since other equipment is installed in the mezzanine, it needs to be repaired and inspected, and people need to move around, which will generate pressure on the roof top plate 6 and cause deformation of the roof top plate 6. Then the fire sprinkler head connected to the roof top plate 6 will drag the fire pipe 7. The fire pipe 7 is generally rigid and will not move. It is fixed to the ceiling of the building by the fixed bracket 8. The only thing that can happen is that the fire sprinkler head is connected to the roof top plate 6 and there is relative displacement, resulting in loss of sealing. The sealing end cover is separated from the fire sprinkler head.

[0056] The corrugated hose 5 can solve this problem by utilizing its flexible and retractable deformation properties with freedom. When people move around, the displacement of the roof top plate 6 is absorbed by the corrugated hose 5, and will not have an adverse effect on the supporting sheath 2, sealing end cover 3 and other structures of the fire sprinkler head and the sprinkler system.

[0057] Preferably, the clean room is constructed using color steel plates. This solution is technically mature and the clean room constructed therefrom has a stable structure.

Conversely, some features of the present invention are described in a single embodiment for brevity, however, these features may also be described in different embodiments alone or in any suitable combination.
