Description

Technical Field

[0001] This invention belongs to the technical field of fire extinguishing devices, specifically relating to a lightweight fire extinguishing device container valve suitable for confined spaces and equipment installation height limitations. This invention is mainly applied to fire extinguishing scenarios in small spaces where conventional fire extinguishing equipment is difficult to install, such as inside equipment enclosures, cabinets, narrow equipment compartments, and small enclosed chambers. It belongs to the technical field of optimized design of core container valves for fixed automatic fire extinguishing devices. Background Technology

[0002] With the widespread use of electrical equipment, precision equipment, and integrated cabinets, the number of various small, enclosed spaces has increased significantly. These spaces are characterized by dense equipment, poor heat dissipation, and a high risk of heat accumulation and fire. Furthermore, the spaces are narrow and compact. Traditional fire extinguishing valves have complex structures, numerous integrated components, and are relatively tall, occupying a large installation space. For space-constrained scenarios such as inside cabinets, equipment mezzanines, and small compartments, conventional equipment cannot be installed, has poor adaptability, and is insufficient to meet the needs of targeted fire suppression in small spaces. Summary of the Invention

[0003] The purpose of this invention is to provide a container valve for a small-space fire extinguishing device. Addressing the technical shortcomings of existing fire extinguishing device container valves, which are large in size and complex in structure, this invention effectively controls the container valve's volume through a simplified integrated structure. This device can be combined with a solenoid valve to achieve both manual and automatic fire extinguishing functions, allowing for installation in confined spaces. Depending on the volume of the protected space, a single-bottle structure or a multi-bottle series structure can be selected, enabling independent shutdown and maintenance as well as automatic spraying triggered by a fire.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a container valve for a small-space fire extinguishing device, featuring a lightweight integrated structure that eliminates redundant fixed structures. The device includes a valve body, a pressure gauge switch, a pressure gauge interface, a solenoid valve interface, a siphon pipe interface, and a multi-cylinder group connection interface. The invention is designed to be linked with the solenoid valve, allowing for manual shut-off via the solenoid valve. The valve is normally open and can be manually closed at any time. During routine equipment maintenance, nozzle replacement, pipeline maintenance, and cylinder disassembly / reassembly, the valve can be manually closed independently, cutting off the upstream extinguishing agent pathway and enabling pressureless disassembly and non-destructive repair of the downstream spraying components and pipeline components. Depending on the protected space volume, multiple cylinder groups can be connected in series via the multi-cylinder group connection interface, delivering the extinguishing gas to the fire area through the same delivery pipeline.

[0005] The advantages of this invention are: it abandons the complex multi-cavity and multi-part structure of traditional valves, and has a simple overall structure, convenient assembly, and low failure rate; it occupies very little installation space, filling the gap in container valves for fire extinguishing devices for small spaces; and it can flexibly select single-cylinder group or multi-cylinder group series mode according to the volume of the protected space to deliver the required fire extinguishing gas to the fire extinguishing area.

[0010] A container valve for a small space fire extinguishing device includes a valve body (2), on which a pressure gauge interface, a pressure gauge gas control valve (3), a solenoid valve interface (8), a siphon tube interface, and a multi-bottle group connection interface are integrated; a container (6) for storing fire extinguishing agent is connected to the valve body (2), and a siphon tube (5) for conveying fire extinguishing agent is provided inside the container (6), and the siphon tube (5) is connected to the siphon tube interface; the solenoid valve interface (8) is used to connect a solenoid valve (9) to control the opening and closing of the fire extinguishing agent pipeline; the multi-bottle group connection interface is used to connect in series with other container valves through a one-way valve (12).

[0011] The valve body (2) is also provided with a pressure gauge (1), and the pressure gauge air circuit control valve (3) is located between the pressure gauge (1) and the valve body (2) to control the opening and closing of the air circuit at the pressure gauge interface.

[0012] The valve body (2) is also provided with a safety valve (4), which has a built-in safety diaphragm for releasing pressure when the pressure in the container (6) exceeds the rated pressure.

[0013] The multi-bottle group connection interface is detachably provided with a screw plug (7). When it is necessary to connect it in series with other container valves, the screw plug (7) is removed and the one-way valve (12) is installed.

[0014] The solenoid valve (9) is normally closed and can be opened electrically or manually.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 and Figure 2 As shown, this embodiment provides a container valve for a small space fire extinguishing device. The specific implementation steps are as follows:

[0017] First, assemble all components into the container valve 2 according to the diagram, ensuring that the sealing performance of each part meets the requirements, and that the solenoid valve 9 is in the normally closed state. Then, remove pressure gauge 1, open the pressure gauge gas control valve 3, connect the external extinguishing agent storage tank to the threaded port of pressure gauge 1, pour the extinguishing agent into container 6, and fill it with the required driving gas, then close the pressure gauge gas control valve 3. Next, disconnect the connection between the external extinguishing agent storage tank and the container valve, and reinstall pressure gauge 1.

[0018] When a fire is triggered, the solenoid valve 9 is opened electrically or manually. The extinguishing agent in container 6 is then propelled through the driving gas into the siphon pipe 5, delivered to the solenoid valve 9, and then sprayed into the corresponding protected area through the extinguishing agent delivery pipeline 11 and finally through the nozzle 10. When the pressure inside the container exceeds the rated pressure, the safety diaphragm in safety valve 4 will rupture under high pressure, releasing the extinguishing agent from the container and preventing container 6 or container valve 2 from bursting due to overpressure.

[0019] Furthermore, this equipment can connect multiple bottle groups in series to achieve simultaneous fire protection and extinguishing of multiple areas. (Please click here.) Figure 2 As shown, the plug 7 of the device is removed, and the one-way valve 12 is installed to connect the two devices together. Activating the solenoid valve 9 of the left device allows the extinguishing agent in the left container to be delivered to protected zone 1 for fire extinguishing. Due to the obstruction of the one-way valve 12, the extinguishing agent from the right device will not enter the left device. Activating the solenoid valve 9 of the right device allows the extinguishing agent in the left device to be delivered through the one-way valve 12 to the container valve 2 of the right device, and together with the extinguishing agent in the right device, it is delivered through the right solenoid valve 9 to protected zone 2 for fire extinguishing. Because the amount of extinguishing agent delivered to protected zone 1 and protected zone 2 is different, the protected space of protected zone 1 is smaller, and the protected space of protected zone 2 is larger.

[0020] This valve automatically opens and automatically sprays extinguishing agent at a stable pressure after a fire is triggered and the device is started. The internal conduction structure of the valve body has low resistance and a stable flow diameter. After opening, it can quickly open the extinguishing agent pipeline, ensuring that the extinguishing agent is sprayed out at a uniform and stable speed, accurately covering the fire point in confined spaces, and achieving rapid fire extinguishing and suppression.
