Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing agent technology, specifically to a rapid release sealing structure for perfluorohexanone gaseous fire extinguishing agent. Background Technology

[0002] Perfluorohexanone is an important alternative to halon fire extinguishing agents. It is a fluorinated ketone compound, a clear, colorless, and odorless liquid that is superpressurized with nitrogen and stored in high-pressure cylinders as part of a fire extinguishing system.

[0003] In response, Chinese Patent Application Publication No. CN210728471U discloses a safe release structure for aircraft fire extinguishing agents. The structure comprises a housing 1, a gasket 2, a red safety release indicator 3, a spring stop ring 4, and a release pipeline assembly. The housing 1 and gasket 2 are fixed to the aircraft fuselage 10 by fasteners 8. The release pipeline assembly is threadedly connected to the housing 1, and the pipeline 7 within the assembly connects to a through hole within the housing 1. The spring stop ring 4 is installed in a positioning circular groove within the housing 1, pressing the red safety release indicator 3 firmly within the housing 1. This structure is used to safely release the fire extinguishing agent from a fixed fire extinguisher to the outside of the aircraft, preventing damage to personnel and the aircraft structure from the sprayed fire extinguishing agent; it can prevent the release pipeline from being blocked by ice or other foreign objects; and it provides a clear visual indication to aircraft ground crew. If the red safety release indicator is found to be punctured, it indicates that the fire extinguishing agent in the fixed fire extinguisher has been safely released to the outside of the aircraft.

[0004] However, in actual use, the release speed of the extinguishing agent is relatively slow, and the extinguisher needs to be sealed after release. The existing seal only uses the valve body, which results in poor overall sealing performance. Furthermore, no testing is performed after sealing. Therefore, improving and perfecting the above-mentioned issues is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a rapid release sealing structure for perfluorohexanone gas extinguishing agent, in order to solve the problems mentioned in the background art, such as the slow overall release speed when releasing the extinguishing agent, and the need to seal the extinguisher after release. Existing seals only use the valve body for sealing, resulting in poor overall sealing performance, and there is no testing after sealing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid release sealing structure for perfluorohexanone gas extinguishing agent, comprising a fire extinguisher body, a connecting top cover installed on the top surface of the fire extinguisher body, an installation ring installed on the outer surface of the connecting top cover, a delivery pipe installed on the right side surface of the installation ring, an installation valve installed on the outer surface of the delivery pipe, a turning valve sleeve installed on the top surface of the installation valve, a delivery cylinder installed on the right side surface of the delivery pipe, and an installation hinge installed on the outer surface of the delivery cylinder; A sealing ring is mounted on the right side surface of the conveying cylinder via a mounting hinge. A sealing gasket is mounted on the outer surface of the sealing ring, and the sealing gasket is adapted to fit the conveying cylinder.

[0007] Preferably, a detection cylinder is installed on the front surface of the conveying cylinder, and a detection ring is installed on one side of the inner wall of the detection cylinder.

[0008] Preferably, a pressure sensor body is installed inside the detection ring, and the detection ring is installed on the inner wall of the front surface of the detection cylinder.

[0009] Preferably, an abutment ring is installed inside the detection cylinder, and an abutment block is fixedly connected to the front surface of the abutment ring.

[0010] Preferably, a telescopic cylinder is installed on the back of the abutment ring, a piston ring is installed at the end of the telescopic cylinder away from the abutment ring, and a spring body is installed inside the telescopic cylinder.

[0011] Preferably, an iron block is installed on one side of the surface of the conveying cylinder, and a magnet is installed on one side of the surface of the sealing ring, and the magnet and the iron block are magnetically attracted to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The rapid-release sealing structure of this perfluorohexanone gas extinguishing agent, through its installation ring, delivery pipe, installation valve, rotating valve sleeve, delivery cylinder, installation hinge, sealing ring, and sealing gasket, allows for rapid release of the extinguishing agent from the delivery pipe and delivery cylinder when the extinguishing agent inside the extinguisher body begins to be released. This is achieved by opening the sealing ring via the installation hinge and then rotating the installation valve sleeve, allowing the extinguishing agent to be rapidly released from the delivery pipe and delivery cylinder. When the release is complete and sealing is required, the rotating valve sleeve is rotated in the opposite direction, and then the sealing ring and sealing gasket are rotated via the installation hinge. The sealing gasket seals the delivery cylinder, ensuring a tight seal after release. Furthermore, the rotating sealing ring attracts the magnet to the iron block, resulting in a stable connection between the delivery cylinder and the sealing ring. This overall stable sealing connection structure demonstrates the practicality of the design.

[0013] The rapid-release sealing structure of this perfluorohexanone gas extinguishing agent, through a set of detection cylinder, detection ring, pressure sensor body, contact ring, contact block, telescopic cylinder, and piston ring, allows for multiple detections. When the sealing ring and gasket are sealed to the delivery cylinder, if gas is delivered from the inside of the delivery pipe to the inside of the delivery cylinder, the gas will contact the piston ring, which will then compress the telescopic cylinder. Simultaneously, turning the valve sleeve will move the contact ring and contact block closer to the back of the pressure sensor body. When the pressure sensor body senses pressure, it can detect a poor sealing effect. The telescopic cylinder contains a magnet, which provides a certain buffering effect. Furthermore, if the overall sealing effect is poor when the valve sleeve is turned, gas will escape from the inside of the delivery cylinder, potentially opening the sealing ring. This indicates that turning the valve sleeve may cause damage. Therefore, this design allows for multiple detections. When the pressure sensor body does not sense pressure, the overall sealing performance is good, demonstrating the functionality of the design. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 One embodiment provided by this utility model: A rapid release sealing structure for perfluorohexanone gas extinguishing agent. The fire extinguisher body 1, pressure sensor body 13, magnet 18, and iron block 19 used in this application are all commercially available products. Their principles and connection methods are existing technologies well-known to those skilled in the art, and therefore will not be elaborated upon here. The structure includes a fire extinguisher body 1, a connecting top cover 2 mounted on the top surface of the fire extinguisher body 1, an installation ring 3 mounted on the outer surface of the connecting top cover 2, a delivery pipe 4 mounted on the right side surface of the installation ring 3, and an installation valve 5 mounted on the outer surface of the delivery pipe 4. The top of the installation valve 5... A rotating valve sleeve 6 is installed on the front surface of the conveying pipe 4. A conveying cylinder 7 is installed on the right side surface of the conveying pipe 4. A mounting hinge 8 is installed on the outer surface of the conveying cylinder 7. A detection cylinder 11 is installed on the front surface of the conveying cylinder 7. A detection ring 12 is installed on one side of the inner wall of the detection cylinder 11. A pressure sensor body 13 is installed inside the detection ring 12. The detection ring 12 is installed on the inner wall of the front surface of the detection cylinder 11. An abutment ring 14 is installed inside the detection cylinder 11. An abutment block 15 is fixedly connected to the front surface of the abutment ring 14. A telescopic cylinder 16 is installed on the back of the abutment ring 14. The telescopic cylinder 16 is located away from the abutment ring 14. A piston ring 17 is installed at one end of the conveying pipe 4. A spring body 20 is installed inside the telescopic cylinder 16. An iron block 19 is installed on one side of the surface of the conveying cylinder 7. A magnet 18 is installed on one side of the surface of the sealing ring 9. The magnet 18 and the iron block 19 are magnetically attracted to each other. When the sealing ring 9 and the sealing gasket 10 are in a sealed state with the conveying cylinder 7, if gas is transported from the inside of the conveying pipe 4 to the inside of the conveying cylinder 7, the gas will come into contact with the piston ring 17. Then the piston ring 17 will squeeze the telescopic cylinder 16. At the same time, turning the valve sleeve 6 will drive the contact ring 14 and the contact ring 16. Block 15 moves closer to the back of the pressure sensor body 13. When the pressure sensor body 13 senses pressure, it can detect that the sealing effect is not good. The telescopic cylinder 16 has a magnet 18 installed inside, which can play a certain buffering role. At the same time, if the valve sleeve 6 is turned, the overall sealing effect is not good. At this time, the gas will be discharged from the inside of the conveying cylinder 7, which will push open the sealing ring 9. This proves that turning the valve sleeve 6 may be damaged. Thus, this design can perform multiple detections. When the pressure sensor body 13 does not sense pressure, the overall sealing performance is good. The sealing ring 9 is mounted on the right side surface of the delivery cylinder 7 via the mounting hinge 8. A sealing gasket 10 is mounted on the outer surface of the sealing ring 9. The sealing gasket 10 and the delivery cylinder 7 are mutually compatible. When the extinguishing agent inside the fire extinguisher body 1 is released, the sealing ring 9 is opened by the mounting hinge 8, and then the mounting valve 5 is opened by turning the rotating valve sleeve 6. Thus, the extinguishing agent is quickly released from the delivery pipe 4 and the inside of the delivery cylinder 7. When the release is complete and sealing is required, the rotating valve sleeve 6 is turned in the opposite direction, and then the sealing ring 9 and the sealing gasket 10 are rotated by the mounting hinge 8. The sealing gasket 10 can seal the delivery cylinder 7, ensuring the sealing effect after release. At the same time, after the sealing ring 9 is rotated, the magnet 18 will be magnetically attracted to the iron block 19, so the connection between the delivery cylinder 7 and the sealing ring 9 is relatively stable, and the overall sealing connection structure is relatively stable.

[0018] Working Principle: When using this device, the operator first connects it to an external power source to provide electrical power. When the extinguishing agent inside the extinguisher body 1 begins to be released, the sealing ring 9 is opened by the hinge 8, and then the installation valve 5 is opened by turning the valve sleeve 6. This allows the extinguishing agent to be rapidly released from the delivery pipe 4 and the delivery cylinder 7. When the release is complete and sealing is required, the valve sleeve 6 is turned in the opposite direction, and then the sealing ring 9 and sealing gasket 10 are rotated via the hinge 8. The sealing gasket 10 seals the delivery cylinder 7, ensuring a tight seal after release. Simultaneously, after rotation, the magnet 18 and iron block 19 are magnetically attracted to each other. When the sealing ring 9 and sealing gasket 10 are in contact with the delivery cylinder... When the space between 7 is sealed, if gas is transported from the inside of the conveying pipe 4 to the inside of the conveying cylinder 7, the gas will come into contact with the piston ring 17, and the piston ring 17 will squeeze the telescopic cylinder 16. At the same time, turning the valve sleeve 6 will drive the contact ring 14 and the contact block 15 to move closer to the back of the pressure sensor body 13. When the pressure sensor body 13 senses the pressure, it can detect that the sealing effect is not good. The telescopic cylinder 16 has a magnet 18 installed inside, which can play a certain buffering role. At the same time, if the overall sealing effect of turning the valve sleeve 6 is not good, the gas will be discharged from the inside of the conveying cylinder 7, which will push open the sealing ring 9. This proves that turning the valve sleeve 6 may cause damage. The above is the working principle of this utility model.

[0019] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
