Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting equipment, and particularly relates to a diversion device for a bottle-type fire extinguisher. Background Art

[0002] Traditional bottle-type fire extinguishers typically consist of a storage tank and a containment valve to control the flow of fire extinguishing agent. The containment valve controls the flow of fire extinguishing agent from the tank and ejects it through a nozzle. Currently, fire extinguishers on the market offer both manual and automatic opening options. Manual opening involves the operator manually pressing or pulling the containment valve to initiate the release of fire extinguishing agent; automatic opening involves an electromagnetic actuator actuating the containment valve to initiate the release of fire extinguishing agent. To ensure the fire extinguisher's multiple uses and its airtightness when not in use, the structure of this type of containment valve is often complex, requiring not only a drive mechanism to automatically reset the valve core but also a sealing mechanism to ensure the valve core's airtightness. This undoubtedly increases the production cost of both the containment valve and the fire extinguisher. Utility Model Content

DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] like Figures 1 to 4 As shown, a flow guide device for a bottle-type fire extinguisher includes a flow guide joint 100 , an isolator 200 , a magnetic attraction portion 300 , a rubber portion 400 and a rotary joint 500 .

[0026] like Figures 1 to 4 As shown, a flow guide device for a bottle-type fire extinguisher includes:

[0027] The flow guide joint 100 is provided with a first interface 110 for discharging liquid;

[0028] The movable structure includes an isolating member 200 rotatably arranged on the first interface 110. When the pressure on the isolating member 200 reaches a preset value, the isolating member 200 can rotate away from the first interface 110, so that the first interface 110 is in a state of communication with the outside, thereby ensuring that the fire extinguishing agent can be released in time; when the pressure on the isolating member 200 is less than the preset value, and there is an angle between the isolating member 200 and the horizontal plane of the first interface 110, the isolating member 200 can rotate toward the first interface 110 and form a blockage on the first interface 110, so that the first interface 110 is in a closed state, thereby ensuring the sealing of the first interface 110. The rotatable design of the isolating member 200 enables the diversion joint 100 to support multiple uses of the fire extinguisher while taking into account the sealing and pressure relief safety. Compared with the conventional container valve structure, the diversion device of the present application has a simple overall structure and low production cost, thereby effectively reducing the production cost of the fire extinguisher and the complexity of the overall structure, while also reducing the maintenance cost of the fire extinguisher.

[0029] Specifically, if Figures 1 to 3 As shown, in this embodiment, the diversion joint 100 is provided with multiple interfaces for diverting and discharging the fire extinguishing agent, and also serves as a gas filling joint. In order to achieve connection with the solenoid valve and the fire bottle body, the diversion joint 100 is provided with a second interface 120 and a third interface 130 that are arranged oppositely and connected. The second interface 120 and the third interface 130 are both provided with a threaded portion (not shown in the figure) and a sealing ring (not shown in the figure), and the solenoid valve and the fire bottle body can be detachably connected to the diversion joint 100 through the second interface 120 and the third interface 130. On the one hand, this design ensures the sealing and stability of the connection between the diversion device and the solenoid valve and the fire bottle body, and on the other hand, it improves the convenience of disassembly and maintenance of the diversion joint 100.

[0030] It is worth mentioning that the solenoid valve is an electromagnetic driver commonly used in fire-fighting equipment.

[0031] Preferably, in this embodiment, the second interface 120 is used as a connection port for the electromagnetic valve, and the third interface 130 is used as a connection port for the fire cylinder. Through the design of the second interface 120, the diversion device can support remote control.

[0032] In order to achieve directional release of the fire extinguishing agent, in this embodiment, a first interface 110 for liquid discharge is provided on the flow guide joint 100. The first interface 110 is vertically arranged between the second interface 120 and the third interface 130, and is connected to the first interface 110 and the second interface 120 respectively; when the solenoid valve is started, the fire extinguishing agent is released through the first interface 110 under the action of the air pressure difference.

[0033] like Figures 1 to 4 As shown, in this embodiment, a movable structure is also provided, comprising an isolator 200 rotatably mounted on the first interface 110. The isolator 200 is made of acrylic sheet and its shape conforms to the shape of the first interface 110. When the fire extinguisher is not in use, the isolator 200 can block the first interface 110, keeping the first interface 110 in a sealed state and ensuring the sealing of the flow-guiding joint 100. When the solenoid valve is activated, the pressure differential within the flow-guiding joint 100 causes the pressure on the isolator 200 to reach a preset value. Under the action of this pressure, the isolator 200 can rotate away from the first interface 110, placing the first interface 110 in an externally connected state, thereby allowing the fire extinguishing agent to be released through the first interface 110. When the fire is extinguished, the diversion device is balanced with the external pressure, so that the pressure on the isolation member 200 is less than the preset value. At this time, the isolation member 200 rotates from the open position toward the first interface 110 and rotates to a position that blocks the first interface 110, so that the first interface 110 is in a closed state, thereby ensuring the sealing of the diversion joint 100.

[0034] In this embodiment, the movable structure also includes a magnetic attraction portion 300 provided on the isolating member 200, wherein the adsorption force of the magnetic attraction portion 300 is less than the pressure when the pressure on the isolating member 200 reaches a preset value; when the pressure on the isolating member 200 reaches the preset value, the isolating member 200 rotates away from the first interface 110 under the action of the pressure, so that the first interface 110 is in a state of communication with the outside; when the pressure on the isolating member 200 is less than the preset value, the isolating member 200 rotates toward the first interface 110 or remains stationary under the action of the adsorption force of the magnetic attraction portion 300, so that the first interface 110 is in a closed state. This design allows the isolating member 200 to automatically rotate according to the pressure, realizing the reuse of the isolating member 200, thereby supporting multiple uses of the fire extinguisher, effectively simplifying the overall structure of the fire extinguisher, and reducing the production and maintenance costs of the fire extinguisher.

[0035] In this embodiment, the magnetic attraction portion 300 is a magnet block, a magnet sheet, or a magnet coating.

[0036] In this embodiment, the isolation member 200 includes a first baffle 210 and a second baffle 220 arranged opposite each other, each of which is rotatably connected to the first interface 110. The magnetic portion 300 includes a first magnetic portion 310 located at an end of the first baffle 210 near the second baffle 220, and a second magnetic portion 320 located at an end of the second baffle 220 near the first baffle 210. When the first magnetic portion 310 and the second magnetic portion 320 are in contact with each other, the first baffle 210 and the second baffle 220 form a whole that is adapted to the diameter of the first interface 110 and cooperate to form a seal against the first interface 110. The coordinated design of the double baffle and the double magnetic portion effectively improves the sealing effect and reliability.

[0037] In this embodiment, the first interface 110 is provided with an annular connecting edge 111, and the first baffle 210 and the second baffle 220 are respectively bonded to the connecting edge 111. The first baffle 210 and the second baffle 220 are provided with a flexible portion 230 for rotation of the first baffle 210 and the second baffle 220. The straight-line distance between the flexible portion 230 and the centerline of the first interface 110 is equal to the radius of the first interface 110. When the first baffle 210 and the second baffle 220 rotate, the flexible portion 230 undergoes elastic deformation. The design of the flexible portion 230 enables the first baffle 210 and the second baffle 220 to rotate and open and close, and utilizes elastic deformation to reduce stress concentration, thereby improving the service life and reliability of the first baffle 210 and the second baffle 220.

[0038] In this embodiment, the movable structure further includes a rubber portion 400, which is located between the first magnetic portion 310 and the second magnetic portion 320 and connected to the first magnetic portion 310 or the second magnetic portion 320. The design of the rubber portion 400 not only further strengthens the seal between the first magnetic portion 310 and the second magnetic portion 320, but also reduces friction and loss between the first magnetic portion 310 and the second magnetic portion 320.

[0039] Preferably, in this embodiment, the rubber portion 400 is provided in two groups, connected to the first magnetic portion 310 and the second magnetic portion 320 respectively, thereby reducing friction between the rubber portion 400 and the magnetic portion 300 .

[0040] It is worth noting that in this embodiment, the isolation member 200 can also be set as an integrally formed circular plate. When the isolation member 200 is designed as an integral whole, one side thereof is rotatably connected to the first interface 110, and the other side is provided with a magnetic attraction portion 300, and the side provided with the magnetic attraction portion 300 forms an adsorption connection with the connecting edge 111 of the first interface 110.

[0041] In this embodiment, a rotatable joint 500 is detachably provided on the first interface 110. The rotatable joint 500 is connected to the first interface 110 and includes a connector 510 that rotates relative to the first interface 110. A gap is provided between the interior of the rotatable joint 500 and the first interface 110 to allow the spacer 200 to rotate. The design of the rotatable joint 500 enables the flow diversion device to rotate the connector 510 according to installation requirements, achieving flexible connection between the flow diversion joint 100 and other components (such as a nozzle or pipe), effectively improving the convenience of maintenance and replacement.

[0042] In this embodiment, the rotary joint 500 is threadedly connected to the first interface 110, and a sealing ring (not shown) is provided between the rotary joint 500 and the first interface 110. This design ensures the connection stability and sealing between the rotary joint 500 and the first interface 110.

[0043] In this embodiment, the flow-guiding joint 100 further includes a fourth interface 140, which is perpendicular to the first interface 110, the second interface 120, and the third interface 130, respectively. A threaded portion (not shown) and a sealing ring (not shown) are provided on the fourth interface 140. A pressure gauge can be detachably connected to the flow-guiding joint 100 via the fourth interface 140 and can detect the pressure inside the flow-guiding joint 100. This design allows the flow-guiding joint 100 to be easily installed with a pressure gauge that can monitor the internal pressure of the flow-guiding joint 100 in real time, providing convenience for operators to observe the internal conditions of the fire extinguisher.

[0044] In this embodiment, the flow-guiding joint 100 also includes a fifth interface 150, which is arranged opposite the fourth interface 140 and at a 90° angle to the first interface 110. A first sealing head 151 is removably provided on the fifth interface 150. The fifth interface 150 communicates with the third interface 130 and serves as a gas filling interface to facilitate filling the flow-guiding device with gas, enabling the flow-guiding device to be activated via a pressure differential, effectively simplifying the structure of the flow-guiding device. The design of the first sealing head 151 ensures the sealing of the fifth interface 150 when not inflated.

[0045] In this embodiment, the flow-guiding joint 100 further includes a sixth interface 160, which is at a 90° angle to the fifth interface 150 and is arranged opposite the first interface 110. A second plugging head 161 is detachably provided on the sixth interface 160. The sixth interface 160 is connected to the third interface 130 and can serve as a gas filling standby interface. This design allows operators to perform filling operations from different directions or connect two filling devices simultaneously, effectively improving operational flexibility and filling speed. It also allows gas filling to be performed through the sixth interface 160 when the fifth interface 150 fails, thereby improving the reliability of the flow-guiding device.
