Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing equipment technology, and in particular to a gas fire extinguishing system. Background Technology

[0002] Gas fire suppression systems are one of the four traditional fixed fire suppression systems. They have advantages such as high fire suppression efficiency, fast fire suppression speed, and no damage to the protected objects. They are widely used in specific places where water cannot be used for fire suppression, such as telecommunications equipment rooms and electrical equipment rooms.

[0003] A gas extinguishing system can protect multiple protected areas, and each protected area requires a starter cylinder. When the entire gas extinguishing system is activated, a single starter cylinder can only activate a limited number of agent cylinders due to volume limitations. For example, a normal 4L-6L starter cylinder can only activate 20-30 90L agent cylinders. When the number of agent cylinders in the entire system is too large, a system using ordinary container valves needs to increase the size of the starter cylinder or increase the number of starter cylinders. This will result in inconsistent starter cylinder sizes within a single system and will also increase the cost of the starter cylinders.

[0004] Therefore, there is an urgent need for a gaseous fire extinguishing system to solve the problem that the entire gaseous fire extinguishing system cannot be activated when the starting cylinder volume is limited. Utility Model Content

[0058] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0059] like Figure 1 As shown in the figure, an embodiment of this utility model proposes a gas fire extinguishing system, characterized in that it includes:

[0060] A starting bottle 1, wherein the starting bottle 1 is filled with pressurized gas;

[0061] Multiple first medicine bottles 2, one second medicine bottle 3, and multiple third medicine bottles 4 are arranged in sequence.

[0062] The first container valve 5 is connected to the gas outlet of the first medicine bottle 2;

[0063] A first starter 8 is connected to the first container valve 5;

[0064] The second air inlet pipe 81 of the first starter 8 on the first medicine bottle 2 located in the first sequential position is connected to the air outlet end of the starter bottle 1; the second air outlet pipe 82 of the first starter 8 on the first medicine bottle 2 in the previous sequential position is connected to the second air inlet pipe 81 of the first starter 8 on the first medicine bottle 2 in the next sequential position.

[0065] The second container valve 6 is connected to the gas outlet end of the second medicine bottle 3;

[0066] The second starter 9 is connected to the second container valve 6. The second air outlet pipe 82 of the second starter 9 is sealed and blocked. The second air inlet pipe 81 of the second starter 9 is connected to the second air outlet pipe 82 of the first starter 8 on the first medicine bottle 2 in the previous sequence position.

[0067] The second container valve 6 has an air intake channel 61 provided on its first air outlet pipe 51;

[0068] The third container valve 7 is connected to the gas outlet of the third medicine bottle 4;

[0069] The third starter 10 is connected to the third container valve 7;

[0070] The second air inlet pipe 81 of the third starter 10 on the third medicine bottle 4, which is adjacent to the second medicine bottle 3, is connected to the air intake channel 61; the second air outlet pipe 82 of the third starter 10 on the third medicine bottle 4 located in the previous sequential position is connected to the second air inlet pipe 81 of the third starter 10 on the third medicine bottle 4 located in the next sequential position.

[0071] The first outlet pipe 51 of the first container valve 5, the first outlet pipe 51 of the second container valve 6, and the first outlet pipe 51 of the third container valve 7 are all connected to the gas distribution pipe 11.

[0072] In this embodiment, the starting bottle 1 is filled with pressurized gas, and the first medicine bottle 2, the second medicine bottle 3 and the third medicine bottle 4 are filled with pressurized medicine gas. The pressure contained in the gas is used to make the gas flow rapidly from the high pressure area to the low pressure area after the switch is turned on.

[0073] The first medicine bottle 2, the second medicine bottle 3, and the third medicine bottle 4 are structurally identical, differing only in their placement order; the first starter 8 and the third starter 10 are structurally identical, and the second air outlet pipe 82 of the second starter 9 is sealed and blocked; the first container valve 5 and the third container valve 7 are structurally identical, and the first air outlet pipe 51 of the second container valve 6 is provided with an air intake channel 61;

[0074] With the second medicine bottle 3 as the boundary, the number of first medicine bottles 2 set in the previous sequence is proportional to the volume of the starter bottle 1. The second air inlet pipe 81 of the first starter 8 on the first medicine bottle 2 located in the first sequence position is connected to the air outlet of the starter bottle 1. The first starter 8 opens the air passage of the first container valve 5 through the pressurized gas in the starter bottle 1, thereby opening multiple first medicine bottles 2.

[0075] The second outlet pipe 82 of the first starter 8 on the first medicine bottle 2 in the previous sequence position is connected to the second inlet pipe 81 of the first starter 8 on the first medicine bottle 2 in the next sequence position. After the first medicine bottle 2 in the previous sequence consumes the pressurized gas in the starter bottle 1, when the remaining pressurized gas is only enough to open the last container valve air passage, it is connected to the second starter 9. The pressurized gas in the starter bottle 1 enables the second starter 9 to open the second container valve 6 air passage, thereby opening the second medicine bottle 2.

[0076] After the second medicine bottle 2 is opened, the gas inside the second medicine bottle 2 enters the third starter 9 on the adjacent third medicine bottle 4 through the gas intake channel 61 on the first gas outlet pipe 51 of the second container valve 6. The third starter 9 opens the third container valve 7, thereby opening the third medicine bottle 4. The second gas outlet pipe 82 of the third starter 10 on the third medicine bottle 4 located in the previous sequence position is connected to the second gas inlet pipe 81 of the third starter 10 on the third medicine bottle 4 located in the next sequence position. The subsequent third medicine bottle 4 also opens the gas passage of the third container valve 7 through the pressurized medicine gas in the second medicine bottle 3. Finally, the gas inside the second medicine bottle 2 is used to open multiple third medicine bottles 4.

[0077] Furthermore, since the volume of the agent bottle is much larger than that of the starting bottle 1, and the pressure of the gas in the agent bottle is also greater than that in the starting bottle 1, there is no need to worry about insufficient pressurized agent gas in the second agent bottle 3 due to diversion, or insufficient pressure of the pressurized agent gas. The first outlet pipe 51 of the first container valve 5, the first outlet pipe 51 of the second container valve 6, and the first outlet pipe 51 of the third container valve 7 are all connected to the gas distribution pipe 11, which further distributes gas to the protected area. This utility model solves the problem that the entire gas extinguishing system cannot be started when the volume of the starting bottle 1 is limited by setting up the gas intake channel 61 to divert the high-pressure agent gas in the second agent bottle 3 to start the subsequent third agent bottle 4.

[0078] like Figures 1-4 As shown, in an optional embodiment of the present invention, the first container valve 5, the second container valve 6, and the third container valve 7 each include:

[0079] Valve body 52, wherein an installation cavity 521 is formed inside the valve body 52;

[0080] A first vent pipe 51 is formed on one side of the valve body 52, and the first vent pipe 51 is coaxial with and connected to the mounting cavity 521.

[0081] A first air inlet pipe 53 is formed at the bottom of the valve body 52. ​​The bottom of the first air inlet pipe 53 is formed with an external threaded portion 531. The first air inlet pipe 53 is connected to the mounting cavity 521.

[0082] The mounting cavity 521 is connected to a sealing cover 54, and a connecting cavity 541 is provided through the sealing cover 54. The connecting cavity 541 is coaxial with and communicates with the mounting cavity 521.

[0083] A venting diaphragm 55 is disposed inside the connecting cavity 541, and the venting diaphragm 55 abuts against the sealing cover 54;

[0084] Piston 56 is slidably disposed in the mounting cavity 521, and a driving cone surface 561 is provided at the end of piston 56 near the first air inlet pipe 53 and the first air outlet pipe 51.

[0085] A first spring 57 is disposed between the piston 56 and the sealing cap 54.

[0086] In this embodiment, the mounting cavity 521 serves two purposes: firstly, it connects the first air inlet pipe 53 and the first air outlet pipe 51 to form an airflow channel; secondly, it provides mounting space for the piston 56. The bottom of the first air inlet pipe 53 has an external thread 531 formed to form a threaded engagement with the internal thread of the air outlet end of the medicine bottle. Under the pressure in the mounting cavity 521 and the elastic force of the first spring 57, the piston 56 is pushed to block the first air outlet pipe 51, thus isolating the first air inlet pipe 53 and the first air outlet pipe 51. When gas enters the first starter 8, the second starter 9, or the third starter 10, or the venting diaphragm 55 is damaged, the pressure in the mounting cavity 521 is reduced. The gas pressure of the first air inlet pipe 53 acts on the driving cone surface 561, overcoming the first spring 57 to push the piston 56 away from the first air outlet pipe 51, thereby achieving communication between the first air inlet pipe 53 and the first air outlet pipe 51, thereby opening the first container valve 5, the second container valve 6, or the third container valve 7.

[0087] like Figure 4As shown, in an optional embodiment of the present invention, the outer diameter of the end of the piston 56 with the driving cone surface 561 is larger than the inner diameter of the first exhaust pipe 51.

[0088] In this embodiment, the piston 56 is used to separate the first air outlet pipe 51 and the first air inlet pipe 53 under normal conditions. The outer diameter of the end of the piston 56 with the driving cone surface 561 is larger than the inner diameter of the first air outlet pipe 51 to ensure that the piston 56 accurately blocks the first air outlet pipe 51.

[0089] like Figure 4 As shown, in an optional embodiment of the present invention, the piston 56 has a recessed cavity 562 formed on the end face near the venting diaphragm 55, and the first end of the first spring 57 is located inside the recessed cavity 562.

[0090] In this embodiment, by positioning the first end of the first spring 57 inside the cavity 562, it is possible to ensure that the first spring 57 accurately and stably supports the piston 56, thereby ensuring that the piston 56 accurately blocks the first air outlet pipe 51.

[0091] like Figure 4 As shown, in an optional embodiment of the present invention, a spring seat 58 is provided on the inner wall of the sealing cover 54, the venting diaphragm 55 is located between the spring seat 58 and the inner wall of the sealing cover 54, the second end of the first spring 57 is located inside the spring seat 58, and the venting diaphragm 55 separates the inner cavity of the spring seat 58 from the connecting cavity 541.

[0092] In this embodiment, the venting diaphragm 55 is located between the spring seat 58 and the inner wall of the sealing cover 54. The venting diaphragm 55 separates the inner cavity of the spring seat 58 from the connecting cavity 541, thereby sealing the connecting cavity 541 and further improving its airtightness. The inner wall of the sealing cover 54 is provided with a spring seat 58, and the second end of the first spring 57 is located inside the spring seat 58. On the one hand, the second end of the first spring 57 is located inside the spring seat 58, and the special shape design enables the spring seat 58 to fit the first spring 57, ensuring that the first spring 57 has reliable axial force while preventing radial displacement, further improving the reliability of the connection between the piston 56 and the first spring 57. On the other hand, since the contact area of ​​the end of the first spring 57 is small and the pressure is relatively large, direct contact between the second end of the first spring 57 and the venting diaphragm 55 is avoided, which could damage the venting diaphragm 55 and affect the airtightness of the connecting cavity 541, further improving the internal stability of the connecting cavity 541.

[0093] like Figure 6 As shown, in an optional embodiment of the present invention, the first starter 8, the second starter 9, and the third starter 10 each include:

[0094] Cylinder body 83, wherein a first sliding cavity 831 is formed inside the cylinder body 83;

[0095] The cylinder body 83 has an external threaded connecting pipe 832 formed at its end. The external threaded connecting pipe 832 is threadedly connected to the connecting cavity 541 and is connected to the first sliding cavity 831.

[0096] A piston plate 84 is slidably disposed inside the first sliding cavity 831. A membrane breaking rod 85 is connected to the first end face of the piston plate 84. The blade 851 of the membrane breaking rod 85 extends into the interior of the external threaded connecting pipe 832.

[0097] The second spring 86 is fitted on the outside of the membrane breaking rod 85, and the two ends of the second spring 86 abut against the inner wall of the piston plate 84 and the first sliding cavity 831, respectively.

[0098] A second intake pipe 81 and a second exhaust pipe 82 are formed on the outside of the cylinder body 83. The second intake pipe 81 and the second exhaust pipe 82 are coaxially arranged and are connected to the first sliding cavity 831. The second end face of the piston plate 84 is close to the connection between the second intake pipe 81 and the second exhaust pipe 82 and the first sliding cavity 831.

[0099] In this embodiment, under normal conditions, the piston plate 84 is pushed away from the external threaded connecting pipe 832 by the second spring 86, so that the blade 851 of the membrane breaking rod 85 is located inside the external threaded connecting pipe 832;

[0100] High-pressure gas enters the first sliding chamber 831 from the second inlet pipe 81. Part of the high-pressure gas contacts the second end face of the piston plate 84 and does work on it in the axial direction of the first sliding chamber 831, causing the piston plate 84 to slide toward the external threaded connecting pipe 832. This causes the blade 851 of the rupture rod 85 to pass through the connecting chamber 541 and contact the venting diaphragm 55. The blade 851 breaks the venting diaphragm 55, thereby opening the first container valve 5, the second container valve 6, or the third container valve 7.

[0101] The high-pressure airflow input from the second intake pipe 81 is continuously entering the second end face of the piston plate 84 near the connection between the second intake pipe 81 and the second outlet pipe 82 and the first sliding cavity 831. After the piston plate 84 moves downward a certain distance, it reaches a dynamic equilibrium state. The remaining high-pressure gas is discharged from the second outlet pipe 82 and connected to other starters.

[0102] like Figures 5-6 As shown, in an optional embodiment of the present invention, the first starter 8, the second starter 9, and the third starter 10 each further include:

[0103] A second sliding cavity 833 is formed inside the cylinder body 83. The second sliding cavity 833 is coaxial with and communicates with the first sliding cavity 831. The second sliding cavity 833 and the second end face of the piston plate 84 are respectively located on both sides of the communication between the second intake pipe 81 and the second exhaust pipe 82 and the first sliding cavity 831.

[0104] A movable push rod 87 is slidably disposed in the second sliding cavity 833, and the inner end of the movable push rod 87 abuts against the second end face of the piston plate 84;

[0105] A mounting base 834 formed on the outside of the cylinder block 83;

[0106] A manual handle 88 is rotatably connected to the fixed base 834, and the manual handle 88 corresponds to the outer end of the movable push rod 87.

[0107] In this embodiment, the second sliding cavity 833 is a backup starting scheme for the starter, used to slide the movable push rod 87. When the starting system fails or other unexpected situations occur, the manual handle 88 connected to the fixed base 834 rotates along the fixed base 834. The manual handle 88 contacts the outer end of the movable push rod 87, thereby pushing the second end face of the piston plate 84 and pushing the rupture rod 85 to pierce the venting diaphragm 55, thus increasing the fault tolerance of the gas extinguishing system.

[0108] like Figures 5-6 As shown, in an optional embodiment of the present invention, the first starter 8, the second starter 9, and the third starter 10 each further include:

[0109] A detachable protective pin 89 is inserted into the fixed base 834, and the protective pin 89 abuts against the side of the manual handle 88 near the movable push rod 87.

[0110] In this embodiment, the protective pin 89 abuts against the side of the manual handle 88 near the movable push rod 87, thereby isolating the manual handle 88 from direct contact with the outer end of the movable push rod 87. When manual activation is required, the protective pin 89 must be removed before the manual handle 88 can be pushed, further increasing the fault tolerance of the gas extinguishing system.

[0111] like Figure 6 As shown, in an optional embodiment of the present invention, the inner diameter of the second sliding cavity 833 is smaller than the inner diameter of the first sliding cavity 831.

[0112] In this embodiment, the inner diameter of the second sliding cavity 833 is smaller than the inner diameter of the first sliding cavity 831, so as to ensure that there is ample space to fill the high-pressure airflow at the connection between the second air inlet pipe 81 and the second air outlet pipe 82 and the first sliding cavity 831.

[0113] like Figure 1 As shown, in an optional embodiment of the present invention, it further includes: a gas transmission pipe connected between the first gas outlet pipe 51 and the gas distribution pipe 11;

[0114] A one-way valve 121 is installed on the gas transmission pipeline, with the outlet end of the one-way valve 121 close to the gas distribution pipeline 11.

[0115] In this embodiment, a one-way valve 121 is installed on the gas supply pipeline. The one-way valve 121 allows high-pressure agent gas to be input from the gas supply pipeline to the gas distribution pipeline 11, and prevents high-pressure agent gas from being input from the gas distribution pipeline 11 to the gas supply pipeline. On the one hand, the one-way valve 121 ensures that the high-pressure agent gas can only flow in a predetermined direction, preventing backflow caused by pressure changes, gravity or other factors. On the other hand, the one-way valve 121 can reduce unnecessary gas circulation, thereby improving the efficiency of the entire gas extinguishing system.

[0116] The present invention provides a gas extinguishing system that, by setting up a gas intake channel 61, diverts the high-pressure agent gas in the second agent bottle 3 to open the subsequent third agent bottle 4, thus solving the problem that the entire gas extinguishing system cannot be started when the volume of the starting bottle 1 is limited.

[0117] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
