Description
Technical Field
[0001] The utility model relates to the technical field of container valves, in particular to a container valve for fire extinguishing agents with multiple starting modes. Background Art
[0002] The container valve, also known as the head valve, is a key component installed on the head of a steel cylinder, primarily responsible for sealing and releasing the fire extinguishing agent within the cylinder. The design and function of the container valve are crucial to ensuring the safety and effectiveness of the fire suppression system. The fire extinguishing agent in this application is initially installed within the building according to fire protection needs.
[0003] The basic functions of container valves include: Sealing function: The container valve must be able to tightly seal the cylinder to prevent leakage of fire extinguishing agent; Release function: When needed, the container valve can be opened quickly to allow the fire extinguishing agent to be released safely; Control function: The container valve is usually equipped with an operating lever or other mechanism so that the user can precisely control the amount of fire extinguishing agent released; Safety function: The container valve design also includes safety devices, such as bursting disks, to ensure that it always remains closed in non-emergency situations to avoid accidental release.
[0004] The structural design of a container valve usually includes the following parts: bottle body: the bottle body is a closed container for storing fire extinguishing agent, usually made of high-strength material to withstand high pressure; bottle mouth: the bottle mouth is the part connecting the bottle body and the container valve, which is connected to the bottle body through the bottle mouth, allowing the fire extinguishing agent to flow out of the bottle body; container valve body: the container valve body is usually made of metal, which is corrosion-resistant and sealing; spring: there is usually a spring inside the container valve, which is used to keep the valve closed; when the operating rod is pushed or rotated, the spring will stretch or compress to open the valve; sealing device: there are also several sealing devices inside the container valve, usually made of rubber, which are used to ensure airtightness when the valve is closed.
[0005] Container valves are widely used in various fire extinguishing systems, such as IG-541 gas fire extinguishing system, HFC-227ea fire extinguishing system, etc. In these systems, container valves are responsible for controlling the release of fire extinguishing agent to ensure that the flames can be extinguished quickly and effectively when a fire occurs.

[0025] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.
[0026] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other unless there is a conflict.
[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.
[0028] like Figure 1-2 As shown, this embodiment proposes a container valve for fire extinguishing agent with multiple start modes, including a container valve body 1, a start device interface is provided at the top of the container valve body 1, a container interface is provided at the bottom end of the container valve body 1, a valve inner cavity is provided at the upper end of the container interface, an air path is provided inside the valve inner cavity, a start pipe interface, a release port and an inflation port are provided at the side end of the container valve body 1, a valve stem body 2 is provided inside the container valve body 1, a valve stem joint 4 is provided at the upper end of the valve stem body 2, a one-way valve core is provided at the inner end of the valve stem joint 4, a container valve core 5 is provided at the upper end of the one-way valve core, a valve core sleeve 6 is provided at the outer end of the container valve core sleeve 6, a valve cover 7 is provided at the upper end of the valve core sleeve 6, a pressure display 3 is provided at the outer end of the container valve body 1, and a passage is provided between the container interface and the release port.
[0029] The pressure indicator 3 is communicated with the bottom space of the container valve through an internal channel.
[0030] The pressure display 3 is connected to the bottom space of the container valve body 1 through an internal channel, and the gas in the cylinder can enter the pressure display 3 to display the gas pressure in the cylinder in real time.
[0031] A safety relief device 8 is provided in the container valve body 1 . A vent hole is installed in the safety relief device 8 , and a safety bursting diaphragm is provided at the inner end of the vent hole.
[0032] A safety bursting diaphragm is installed in the safety relief device 8. When the gas in the cylinder exceeds a certain value, the safety bursting diaphragm bursts, and the gas in the cylinder flows out through the vent hole of the safety relief device 8, reducing the gas pressure in the cylinder and ensuring the safety of the cylinder.
[0033] The container interface is threadedly connected to the cylinder. When the valve is closed, the gas in the cylinder is sealed at the bottom of the container valve.
[0034] A stainless steel cylinder 10 is provided at the inner end of the container interface, and a thread is provided at the outer end of the container interface. The stainless steel cylinder 10 is used to strengthen the strength of the threaded interface. The stainless steel cylinder 10 is usually matched with the inner end of the container interface through a rubber ring to prevent slipping. When the container valve body 1 is installed on the cylinder through the thread, it is squeezed and fitted.
[0035] A control system for a fire extinguishing agent container valve with multiple start modes is disclosed. The control system is an integrated electronic control unit for receiving external signals and controlling the start and close of the container valve body 1. The control system includes a sensor, a microprocessor, an actuator, and a communication interface.
[0036] The control system is an integrated electronic control unit (ECU) that receives external signals and controls the opening and closing of the container valve. The control system includes components such as sensors, microprocessors, actuators, and communication interfaces.
[0037] The process of the control system operating the container valve is as follows:
[0038] Sensor installation: Install pressure sensors, temperature sensors, position sensors, etc. at key locations of container valves to monitor the pressure, temperature, and position status of valve components in real time.
[0039] Signal Reception: The control system receives a start signal from the fire alarm system or other remote control equipment through a communication interface. This signal can be a digital signal or a command transmitted via a wireless or wired network.
[0040] Data processing: The microprocessor receives sensor data and external start signals for analysis and processing. If a fire is detected or a start command is received, the microprocessor will execute the preset control logic.
[0041] Starting device activation: The microprocessor sends a control signal through the actuator to activate the starting device. The actuator can be electric, using a motor to drive the valve stem 2, or pneumatic, using controlled air pressure to move the valve stem 2.
[0042] Valve Opening: After the triggering device is activated, the valve stem 2 is precisely controlled to move, and the valve stem connector 4 moves accordingly, causing the one-way valve core to open, allowing air pressure to act on the container valve core 5. At the same time, the container valve core 5 moves outward under the action of pressure, opening the passage between the container interface and the release port.
[0043] Fire extinguishing agent release: As the container valve core 5 is opened, the fire extinguishing agent stored in the container is rapidly ejected through the gas channel and the release port, covering the fire source area and achieving rapid fire extinguishing.
[0044] Pressure monitoring and feedback: Throughout the firefighting process, the control system monitors the data from the pressure display 3 in real time and analyzes it through the microprocessor. If the pressure is abnormal, the control system can adjust the valve opening to ensure stable release of the fire extinguishing agent.
[0045] Fire extinguishing is completed and the valve is closed: Once the gas fire extinguishing agent is sprayed, or a closing command is received, the control system will stop functioning and return the valve stem 2 and the container valve core 5 to the closed position through the actuator, thereby resealing the container interface.
[0046] Status reporting: The control system can report the fire extinguishing status and the working status of the container valve to the remote monitoring center through the communication interface for subsequent maintenance and inspection.
[0047] By adding such a control system, the container valve for fire extinguishing agents with multiple activation modes can not only achieve more precise and intelligent control, but also improve fire extinguishing efficiency and safety, while facilitating remote monitoring and management.
[0048] When using this application:
[0049] Initial state: Under normal conditions, the valve stem 2 inside the container valve body 1 is in the closed position, the one-way valve core prevents the fire extinguishing agent from flowing out, and the container valve core 5 also closes the container interface to prevent the fire extinguishing agent from leaking from the container;
[0050] Start signal reception: When a fire is detected, the start device is connected to the container valve body 1 through the start device interface to receive the start signal. This start signal can be generated by manual operation or circuit signal;
[0051] Actuator activation: The actuator receives a signal and triggers the actuating mechanism inside the vessel valve body 1. This may include electrical, pneumatic, or mechanical actuation, depending on the specific actuating device design;
[0052] Valve opening: After the starter is activated, the valve stem 2 is pushed, and the valve stem connector 4 moves accordingly, causing the one-way valve core to open, allowing air pressure to act on the container valve core 5. At the same time, the container valve core 5 moves outward under the action of pressure, opening the passage between the container interface and the release port;
[0053] Fire extinguishing agent release: As the container valve core 5 opens, the fire extinguishing agent stored in the container is quickly ejected through the gas channel and the release port, covering the fire source area and achieving rapid fire extinguishing;
[0054] Pressure monitoring: During the entire fire extinguishing process, the pressure display 3 monitors the pressure changes in the container in real time;
[0055] Fire extinguishing is completed: Once the gas fire extinguishing agent is sprayed, the starting device will stop working, the valve stem body 2 and the container valve core 5 will return to the closed position, and the container interface will be resealed. After the container valve is opened, the gas will be sprayed out and cannot be closed in the middle. Return the bottle group to the factory for inspection and inflation before reinstallation and use.
[0056] In the initial state, when the valve is closed, the container interface portion at the lower portion of the container valve body 1 is connected to the space inside the cylinder, carrying the fire extinguishing agent gas, and there is no gas in the space above the valve;
[0057] When in startup state:
[0058] 1. The ejector pin of the top starting device is pressed down, and the container valve core 5 and the valve core sleeve 6 are pressed down, driving the valve stem body 2 and the valve stem joint 4 to move downward. The container interface at the lower part of the valve and the side release port form a passage, and the gas fire extinguishing agent enters the side release port from the container interface for release.
[0059] 2. High-pressure gas enters from the side starting pipe interface, enters the upper part of the valve through the gas path, and presses down the one-way valve core in the valve stem joint 4 due to the pressure of the high-pressure gas. At this time, the high-pressure gas at the lower part of the one-way valve core enters the upper space of the one-way valve core, and enters the upper part of the valve core sleeve 6 through the internal air flow channel. The high-pressure gas presses down the container valve core 5 and the valve core sleeve 6. The container valve core 5 and the valve core sleeve 6 drive the valve stem body 2 and the valve stem joint 4 to move downward through the contact surface (the valve stem body 2 and the valve stem joint 4 are connected by threads). The container interface at the lower part of the valve and the side release port form a passage, and the gas fire extinguishing agent enters the side release port from the container interface for release.
[0060] 3. Gas enters from the side release port, enters the valve cavity, enters the upper part of the valve through the air path, and presses down the one-way valve core in the valve stem joint 4 due to the pressure of the high-pressure gas. At this time, the high-pressure gas at the lower part of the one-way valve core enters the upper space of the one-way valve core, and enters the upper part of the valve core sleeve 6 through the internal air flow channel. The high-pressure gas presses down the container valve core 5 and the valve core sleeve 6. The container valve core 5 and the valve core sleeve 6 drive the valve stem body 2 and the valve stem joint 4 to move downward through the contact surface (the valve stem body 2 and the valve stem joint 4 are connected by threads). The container interface at the lower part of the valve and the side release port form a passage, and the gas fire extinguishing agent enters the side release port from the container interface for release.
[0061] There is no pressure inside the release port of the release hose under normal circumstances, so gas can enter through it and start the valve. Once the gas in the cylinder is released, it enters the normal release process and the gas is ejected from it.
[0062] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
