Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing systems, in particular to a gas fire extinguishing agent container valve with integrated liquid level monitoring and a fire extinguishing agent bottle group with the gas fire extinguishing agent container valve. Background Art

[0002] Fire extinguishing systems, as important safety equipment in infrastructure and large-scale industrial equipment, are generally divided into four categories according to the type of fire extinguishing medium: water, foam, gas, and dry powder. Among gas fire extinguishing systems, liquefied gas fire extinguishing agents, including heptafluoropropane (HFC227ea, or FM200), perfluorohexanone (FK-5-1-12, or Novec1230), which are stored in liquid form, are the most common. Currently, such systems are divided into two types: internal storage pressure and external storage pressure. In internal storage pressure fire extinguishing systems, the fire extinguishing agent cylinder group is usually monitored for fire extinguishing agent leakage by pressure monitoring; in external storage pressure fire extinguishing systems, the fire extinguishing agent cylinder group does not normally have driving gas, and driving gas is only added from the outside when extinguishing a fire. Therefore, pressure monitoring cannot be used for leakage monitoring, and fire extinguishing agent leakage is mainly monitored by independently installed liquid level gauges. The pressure monitoring method only monitors the pressure of the nitrogen used to drive the fire extinguishing agent, and the situation of the liquid fire extinguishing agent stored inside is indirect or delayed; the independently installed liquid level gauge requires a separate and larger installation interface on the upper part of the fire extinguishing agent container, which increases the manufacturing complexity of such containers and also increases the probability of chronic leakage of the fire extinguishing agent. Some liquid level gauges use contact-type electronic, capacitive and other electrical components, which are enclosed in a fire extinguishing agent container with a certain degree of corrosiveness for a long time, reducing their reliability and making it inconvenient to replace them after damage. Utility Model Content

[0003] In response to the deficiencies in the prior art, the utility model provides a gas fire extinguishing agent container valve with integrated liquid level monitoring and a fire extinguishing agent bottle group having the gas fire extinguishing agent container valve.

[0009] Furthermore, the fire extinguishing agent bottle group also includes a siphon tube assembly, the top end of the siphon tube assembly is inserted into the container valve body, and the bottom end of the siphon tube assembly extends to the bottom end of the fire extinguishing agent container.

[0010] In order to facilitate the conduction between the siphon tube assembly and the first and second connectors, a conductive sleeve is provided in the inner cavity of the container valve body, and the conductive sleeve is separated from the inner wall of the container valve body by an insulating sleeve. The top of the siphon tube assembly can press the conductive sleeve and conduct with the conductive sleeve, and the end of the connector extending to the inner cavity of the container valve body is threadedly connected to the conductive sleeve to achieve conduction.

[0018] (3) The internal pressure fire extinguishing agent bottle group uses liquid level monitoring to monitor fire extinguishing agent leakage.

The integrated liquid level monitoring has the ability of continuous and uninterrupted monitoring without human intervention, which is more suitable for unmanned places;

[0021] (6) The liquid level monitoring device is integrated inside the bottle group, there is no pressure difference between the components, it is more durable and leak-free;

[0022] (7) The integrated liquid level device relies on the fire extinguishing agent to lower the float, forming a simple switch structure, which is connected to the monitoring circuit to easily realize leakage monitoring. Common liquid level switches, such as pressure type, capacitance type, electronic type, reed switch type and ultrasonic type, must rely on the reliability of these electrical or electronic components, especially since the fire extinguishing agent has a certain corrosiveness, and long-term sealing inside brings uncertainty to the device.

[0023] (8) The liquid level device is converted into an electrical signal through the back-end monitoring device, which is more convenient for daily leakage monitoring and also facilitates remote display and monitoring of the monitoring signal. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0035] like Figure 1 The fire extinguishing agent cylinder assembly shown includes a fire extinguishing agent container 1, a fire extinguishing agent 5, and a driving gas 6 disposed within the fire extinguishing agent container 1. A gas fire extinguishing agent container valve 2 with integrated liquid level monitoring is installed at a mounting interface 1a at the top of the fire extinguishing agent container 1. A stamping interface 1b is also provided at the top of the fire extinguishing agent container 1. A siphon assembly 3 is installed within the fire extinguishing agent container 1, and a liquid level float assembly 4 is mounted on the siphon assembly 3.

[0036] Among them, the fire extinguishing agents 5 are all media without conductive ability, and the fire extinguishing agents cannot be used as conductors to transmit on-off signals; for the fire extinguishing agent bottle group with external storage pressure, the driving gas 6 will be filled into the fire extinguishing agent bottle group from the power bottle group with external storage pressure only when extinguishing a fire, while the internal storage pressure bottle group is always filled with driving gas 6.

[0037] Specifically, combined Figure 2 、 Figure 3 As shown, the gas fire extinguishing agent container valve 2 with integrated liquid level monitoring includes a container valve body 21, an actuator 22 provided on the container valve body 21, and a valve core assembly 23 provided in the container valve body 21. The container valve body 21 is also provided with a liquid level signal acquisition assembly 24 capable of monitoring the liquid level. The inner cavity of the container valve body 21 is provided with a conductive sleeve 26, and the conductive sleeve 26 is separated from the inner wall of the container valve body 21 by an insulating sleeve 25. The top end of the siphon tube assembly 3 can press the conductive sleeve 26 and conduct with the conductive sleeve 26. The liquid level signal acquisition assembly 24 can conduct with the conductive sleeve 26. In addition, the bottom end of the container valve body 21 is also provided with a set screw 27 and a set screw 28 parallel to the horizontal plane.

[0038] The actuator 22 may be gas-driven as shown, or electromagnetically driven or electric-explosive driven. When a fire occurs, the actuator 22 punctures the sealing diaphragm on the upper portion of the container valve body 21 downward, or the actuator 22 pushes down other sealing structures, such as a valve core, so that the sealing gas on the upper portion of the valve core assembly 23 is released. The valve core assembly 23 is then driven upward by the driving gas from the lower portion, thereby opening the fire extinguishing agent passage. Simultaneously, the fire extinguishing agent 5 in the container is driven by the driving gas 6 from the upper portion and is output through the siphon assembly 3 to the valve outlet 2a, ultimately achieving the discharge of the fire extinguishing agent and extinguishing the fire.

[0039] Among them, the side of the container valve body 21 is provided with an installation cavity for installing the liquid level signal acquisition component 24, the installation cavity passes through the outer wall of the container valve body 21 and is connected to the inner cavity of the container valve body 21, the liquid level signal acquisition component includes a connector 1 2401, a connector 2 2403 and a connector 3 2404, the connector 3 2403 is fixed to the outside of the container valve body 21 and is threadedly connected to the container valve body 21, the connector 3 2403 can press the connector 1 2401 and the connector 2 2403, an O-ring 2412 is provided at the connection between the connector 3 2403 and the installation cavity, and a protective cover 2405 is provided on the outer cover of the connector 3 2403, the connector 1 2401 is arranged in the installation cavity, an insulating sleeve 1 2402 is provided between the connector 1 2401 and the inner wall of the installation cavity, and an O-ring 1 2410 is provided between the connector 1 2401 and the insulating sleeve 1 2402. The left end of the connector 1 2401 extends to the inner cavity of the container valve body 21 and is threadedly connected to the conductive sleeve 26. The right end of the connector 2 2403 is inserted into the inner cavity of the connector 3 2404. The left end of the connector 2 2403 extends to the outside of the inner cavity of the connector 3 2404 and abuts against the right end of the connector 1 2401, thereby realizing the conduction between the connector 1 2401 and the connector 2 2403. An insulating pad 2411 is provided between the end face of the connector 2 2403 extending outside the inner cavity of the connector 3 2404 and the left end face of the connector 3 2404, thereby realizing the insulation isolation between the connector 2 2403 and the connector 3 2404. The connector 2 and the connector 3 are respectively connected to the alarm system through the wire 2408 and the wire 2407. The wire 2408 is provided with an insulating sleeve 2409. The protective cover 2405 is provided with a wire outlet hole for the wire to pass through, and a rubber sleeve 2406 is provided in the wire outlet hole.

[0040] Specifically, the top of the siphon assembly 3 is inserted into the container valve body 21, and the conductive sleeve 26 and the insulating sleeve 25 are pressed tightly, and the bottom end of the siphon assembly 3 extends to the bottom end of the fire extinguishing agent container 1, combined with the Figure 4-6As shown, the siphon assembly includes a siphon body 31, a conductor 1 32, a conductor 2 33 and an insulating patch 34. The outer wall of the siphon body 31 is provided with a groove 1 31a, a groove 2 31b and a groove 31c. The groove 1 31a and the groove 2 31b are arranged opposite to each other, and the groove 1 31a and the groove 3 31c are connected. The top of the groove 1 31a extends outward from the siphon body 31. The conductor 1 32 fits in the groove 2 31b. The conductor 2 33 fits in the groove 1 31a and the groove 3 31c. The top of the conductor 2 33 extends outward from the groove 1 31a and contacts the bottom end of the conductive sleeve 26, so that the conductor 2 33 is connected to the conductive sleeve 26. The bottom end of the container valve body 21 is connected to the conductor 1 32 through the set screw 1 27. The bottom end of the container valve body 21 is separated from the conductor 2 33 by the set screw 25. The set screw 1 27 is made of metal. The container valve body 21 is connected to the conductor 1 32, and the set screw 28 is made of engineering plastic, which separates the conductor 2 33 from the container valve body 21. The insulating patch 34 is attached to the outside of the conductor 2 33 and does not completely cover the conductor 2 33, that is, the upper part of the conductor 2 33 is attached with the insulating patch 34, and the lower part located in the groove 31c is not attached with the insulating patch 34. The length of the insulating patch 34 is determined according to the liquid level corresponding to the minimum allowable leakage. In addition, the lower end of the siphon body 31 is fixed with a limiting structure 35. The siphon body 31 and the lower limiting structure 35 are both made of engineering plastic. The length of the conductor 1 32 and the conductor 2 33 or the position reached by the lower part can be determined according to the liquid level corresponding to the maximum allowable leakage, or it can be determined up to the limiting structure 35 at the bottom of the siphon. This length also determines the alarm duration during the leakage of the fire extinguishing agent.

[0041] The siphon assembly 3 is provided with a liquid level float assembly 4, specifically, in combination with Figure 7 、 Figure 8 As shown, the liquid level float assembly includes a float body 41 and a group of conductive springs 42. The float body 41 is sleeved outside the siphon body 31 and can slide up and down along the siphon body 31. Two notches 41b are left at the top of the float body 41. The top of the conductive spring 42 is fixed in the notch 41b by screws 43. The notch 41b can avoid direct conduction with metal structures such as the valve body. The bottom end of the conductive spring 42 extends downward into the float body 41, and the two conductive springs 42 are respectively slidably connected to the grooves. The bottom ends of the two conductive springs 42 in the first groove 31a and the second groove 31b have an arc-shaped structure, which can reduce friction during the sliding process and prevent them from getting stuck. The float body 41 can be made of a solid non-metallic material with a density lower than that of the fire extinguishing agent, usually engineering plastic. When engineering plastic is used, the float body 41 needs to be covered with a metal ring 44. The metal ring 44 can make the two conductive springs 42 conductive. A hollow metal material can also be used. When metal material is used, the metal ring 44 between the two conductive springs 42 can be omitted.

[0042] When the fire extinguishing agent is full, the liquid level float assembly 4 floats on the liquid surface as a whole, the right conductive spring 42 contacts the insulating patch 34 on the second conductor 33, the entire circuit is in a disconnected state, and the liquid level monitoring alarm and display system 7 displays the working status, such as Figure 9 As shown;

[0043] When the fire extinguishing agent leaks, the liquid level float assembly 4 as a whole drops with the liquid level, the right conductive reed 42 contacts the conductor 2 33, the entire circuit is connected, and the liquid level monitoring alarm and display system 7 emits an audible or (and) optical alarm, such as Figure 10 shown.

[0044] The liquid level monitoring device of the present invention can be combined with various types of container valves, such as those adopting different types of starters, including gas-driven starters, electromagnet-driven starters, and electric squib-driven starters; it can also be container valves with different sealing action types, including sealing diaphragm-driven type and valve core-driven type.

[0045] The integrated liquid level monitoring device can be used not only for liquefied gas fire extinguishing devices, but also for all liquid containers that need to be controlled by valves and have siphons. It can also be a liquid level float of the structure attached to a separate tubular material of the structure.

[0046] The first and second conductors on the siphon assembly can be metal sheets fixed to the siphon by gluing, thread pressing, etc., or can be metal conductive layers obtained by printing or other processes;

[0047] The material of the conductor 1 and conductor 2 on the siphon assembly and the conductive reed on the liquid level float can be a single metal with corrosion resistance and conductivity, or a composite metal with corrosion resistance and good conductivity plated on the surface of an ordinary material, or other non-metallic materials that meet the requirements of this function;

[0048] The insulating patch on the upper part of the second conductor can be attached to the surface of the second conductor by means of pasting, sleeve coating, spraying or other methods or processes.

[0049] The integrated liquid level monitoring device can realize the collection of two or more liquid level signals by increasing the number of external wires and the conductors, liquid level floats, and conductive reeds associated therewith.

[0050] The float body can be made of a solid non-metallic material with a density lower than that of the fire extinguishing agent, usually engineering plastic, or a hollow metal material. When a metal material is used, the metal connector between the two springs can be omitted.

[0051] The two wires connected to the liquid level signal acquisition component can be remotely transmitted to a centralized or independent display or (and) alarm device, or local signals can be obtained by adding a power supply, indicator light or (and) buzzer on site.

[0052] The signals collected by the utility model can also be used as medium spraying signals of the fire extinguishing system.
