Description

Technical Field

[0001] This invention relates to the field of fire safety technology, specifically to a puncture valve that is easy to install and its fire protection system. Background Technology

[0002] The puncture valve is a key safety device widely used in fire suppression systems for new energy storage battery cabinets. Its core function is to rapidly activate upon receiving an electrical signal in the early stages of thermal runaway in a battery module, puncturing its internal seal to release fire extinguishing agents (such as perfluorohexanone) to the fault area. This enables rapid and precise fire suppression and explosion control, serving as a crucial barrier to ensure the overall safety of the energy storage system. With the rapid expansion of the global energy storage industry, the reliability, response speed, and engineering applicability of puncture valves have become a focus of industry attention.

[0003] However, the valve bodies of existing puncture valves are mostly cylindrical structures without independent mounting components. This means that when installed on energy storage containers, they must rely on the connected fire-fighting pipelines for suspension and fixation. The pipelines require additional pipeline supports to support and fix both the fire-fighting pipelines and the puncture valves. Without pipeline supports, the valve body cannot be installed independently and stably. This not only increases the complexity of system integration but also affects the efficiency and accuracy of installation.

[0004] Therefore, there is an urgent need for an easy-to-install puncture valve and its fire protection system that can be independently and securely installed on the energy storage container while providing support for the fire protection pipeline connected to the puncture valve, eliminating the dependence on pipeline supports, thereby saving pipeline support costs and making the overall fire protection system simpler and cheaper. Summary of the Invention

[0005] The purpose of this invention is to provide a puncture valve and its fire protection system that are easy to install, so as to solve the problems mentioned in the background art and achieve the purpose of installing the puncture valve without relying on pipeline suspension and facilitating independent installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An easy-to-install puncture valve includes: The valve body has a cubic structure with a valve cavity inside. The valve body has an inlet, a first outlet, and a second outlet located lower than the inlet and the first outlet integrally formed on the outside. A fixing plate is fixedly installed on the top of the valve body; Mounting holes are provided on the mounting plate.

[0007] As a further aspect of the present invention: to facilitate the replacement and maintenance of the puncture component, and to prevent the puncture component from excessively screwing in and damaging the seal through the stepped surface limit, while ensuring the sealing reliability of the valve body in the non-triggered state, the puncture valve further includes: A sealing element is fixedly disposed within the valve cavity to seal and isolate the flow channel between the inlet and the second outlet. An installation groove is formed at the bottom of the valve body and communicates with the valve cavity, and the diameter of the installation groove is larger than the diameter of the valve cavity. A piercing component is detachably installed in the mounting groove for piercing the seal. As a further aspect of the present invention: to facilitate the replacement and maintenance of the puncturing component, the inner wall of the mounting groove is provided with an internal thread, and the puncturing component is threadedly connected in the mounting groove.

[0008] As a further aspect of the present invention: to ensure that the piercing member can move along a predetermined axial trajectory to pierce the seal upon triggering, the piercing member includes: A sleeve, the end of which is formed with a connector that mates with the thread in the mounting groove; A piercing needle is movably mounted inside the sleeve, and the piercing needle can move axially along the sleeve to probe into the valve cavity and pierce the seal.

[0009] As a further aspect of the present invention: to facilitate the replacement of the seal, a sealing groove is provided in the valve cavity, and a thread is provided in the sealing groove, and the seal is threadedly connected in the sealing groove.

[0010] As a further aspect of the present invention: to further facilitate the installation and disassembly of the seal and improve the maintainability of the puncture valve, the seal includes: A hexagonal groove is formed inside the seal and extends vertically through the seal. A sealing diaphragm covers one end of the hexagonal groove near the fixed plate.

[0011] As a further aspect of the present invention: in order to reduce the overall weight, material costs and installation load, the bottom sides of the valve body are symmetrically provided with side grooves for weight reduction.

[0012] As a further aspect of the present invention: to facilitate the installation and disassembly of the puncture valve and the connecting fire pipeline, the ports of the inlet, the first outlet and the second outlet all protrude outward to form connecting nozzles, and the connecting nozzles are provided with external threads.

[0013] The present invention also provides an energy storage container fire protection system, which includes a puncture valve as described above.

[0014] As a further aspect of the present invention: to enable the puncture valve, which is independently and securely installed on the energy storage container, to provide support for the fire-fighting pipeline and to quickly and accurately guide the fire-fighting agent to the fault area through the fire-fighting pipeline and nozzles, the energy storage container fire-fighting system further includes: The valve body is fixedly installed on the energy storage container through mounting holes and fasteners on the fixing plate; The fire-fighting pipeline is connected to the inlet, first outlet, and second outlet of the valve body and is used to transport fire-fighting agents. The nozzle is connected to the second outlet of the valve body via a fire-fighting pipeline and is used to deliver fire-fighting agents to the fault area inside the energy storage container.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention features a novel structure. Through a fixing plate and mounting holes, the puncture valve is independently mounted on the energy storage container using bolts and other fasteners. Simultaneously, the puncture valve, fixed to the energy storage container, connects to the fire protection pipeline and also serves to support it, avoiding the dependence on pipeline supports inherent in traditional cylindrical valve bodies and fire protection pipelines. The cubic valve body structure facilitates the placement and positioning of the puncture valve, improving installation efficiency and structural stability. The puncture component is threaded into the mounting groove of the valve body, allowing for quick replacement without disassembling the valve body and connected fire protection pipelines. This simple and fast operation reduces maintenance time and lowers the risk of system downtime. The sealing element is threaded into the sealing groove of the valve cavity. The sealing diaphragm can be replaced independently when punctured or the sealing element ages, without replacing the entire valve body, reducing maintenance costs and extending the puncture valve's lifespan.

[0020] Please see Figure 1-10In this embodiment of the invention, a puncture valve that is easy to install includes a valve body 1. The valve body 1 has an overall cubic structure, which facilitates the placement and installation of the puncture valve as a whole. A valve cavity 11 is formed inside the valve body 1 for the flow of fire-fighting agents. An inlet 12, a first outlet 13 and a second outlet 14 are integrally formed on the outside of the valve body 1. The inlet 12, the first outlet 13 and the second outlet 14 are all connected to the valve cavity 11. The ports of the inlet 12, the first outlet 13 and the second outlet 14 all protrude outward to form connecting nozzles, and the connecting nozzles are all provided with external threads, which facilitates the connection, installation and removal of the valve body 1 and the fire-fighting pipeline 6. Inlet 12 and first outlet 13 are respectively located on both sides of valve body 1 and are threadedly connected to fire pipeline 6 for the inflow and outflow of fire-fighting agent. Second outlet 14 is connected to sprinkler head 7 through fire pipeline 6 and the position of second outlet is lower than inlet 12 and first outlet 13, so that when second outlet 14 is connected to inlet 12, fire-fighting agent can flow from the higher inlet 12 to the lower second outlet 14 by gravity and be discharged from sprinkler head 7 to the fault area.

[0021] like Figure 1 and Figure 2 As shown, a fixing plate 4 is horizontally fixed to the top of the valve body 1. The fixing plate 4 can be integrally formed on the top of the valve body 1 or separately welded to the top of the valve body 1. The fixing plate 4 has mounting holes 41 for fixing the valve body 1 to the energy storage container with fasteners, allowing the puncture valve to be installed independently. Side grooves 16 are symmetrically formed on both sides of the bottom of the valve body 1, giving the bottom of the valve body 1 a Z-shaped structure with a central boss and stepped surfaces on both sides, which helps reduce the weight of the valve body 1. In this embodiment, the mounting holes 41 are specifically configured as two oblong holes symmetrically arranged about the center of the upper surface of the fixing plate 4.

[0022] like Figure 3 and Figure 4 As shown, a mounting groove 15 is provided at the bottom of the valve body 1. The mounting groove 15 connects to the valve cavity 11, and an internal thread is provided on the inner side wall of the mounting groove 15 for threaded connection of the piercing member 3. The diameter of the mounting groove 15 is larger than the diameter of the valve cavity 11, so that a stepped structure is formed between the mounting groove 15 and the valve cavity 11. This can serve as a mechanical stop surface to limit the screwing depth of the piercing member 3, avoiding excessive screwing and damage to the seal or valve cavity structure. It also facilitates the disassembly and installation of the seal 2. A sealing groove 111 is provided in the valve cavity 11, and an internal thread is provided on the inner side wall of the sealing groove 111 for threaded connection of the seal 2. The sealing groove 111 is located between the flow channels of the inlet 12 and the second outlet 14, so that the seal 2 installed in the sealing groove 111 can isolate the inlet 12 and the second outlet 14. The axial direction of the sealing groove 111 is consistent with the axial direction of the mounting groove 15, which facilitates the piercing member 3 installed in the mounting groove 15 to pierce the seal 2 in the sealing groove 111.

[0023] like Figure 1and Figure 5 As shown, the piercing component 3 is detachably installed in the mounting groove 15. The piercing component 3 includes a sleeve 31 and a piercing needle 32. A connector 311 is formed at the end of the sleeve 31. The outer peripheral wall of the connector 311 is provided with external threads for threaded connection with the mounting groove 15, so that the piercing component 3 can be threadedly connected in the mounting groove 15, which facilitates installation and disassembly when maintaining and replacing the piercing component 3. The piercing needle 32 is embedded in the sleeve 31 with the needle tip facing the seal 2. The piercing needle 32 can slide along the axial direction of the sleeve 31 in the sleeve 31, so that the needle tip of the piercing needle 32 can penetrate into the valve cavity 11 and pierce the seal 2. The general working principle of the piercing component 3 is that the piercing component 3 has an electric ignition device. When a start signal is received and the electric ignition device is triggered, the electric ignition device ignites and explodes, thereby driving the piercing needle 32 to slide out in the sleeve 31 and destroy the corresponding seal 2.

[0024] like Figure 4 and Figure 6 As shown, the outer peripheral wall of the seal 2 has external threads for threading the seal 2 into the sealing groove 111, facilitating disassembly, replacement, and installation of the seal 2 after aging or puncture. The seal 2 has a through-hole hexagonal groove 22 for easy installation and removal with a suitable tool (such as an Allen wrench). The top of the hexagonal groove 22 (the end closest to the fixing plate 4) is covered with a sealing diaphragm 21 to seal and isolate the inlet 12 and the second outlet 14.

[0025] like Figure 7 As shown, an energy storage container fire suppression system disclosed in an embodiment of the present invention may include a puncture valve as described above. It should be understood that this energy storage container fire suppression system also possesses the advantages described above regarding the puncture valve. Figure 7 As shown, the energy storage container fire protection system includes the aforementioned puncture valve, energy storage container 5, fire pipe 6, and sprinkler head 7, wherein, as... Figure 8 As shown, the valve body 1 of the puncture valve is fixedly connected to the top of the energy storage container 5 through the mounting hole 41 on the fixing plate 4 and fasteners. In this embodiment, the fasteners are bolts. A threaded hole is provided on the top of the energy storage container 5. After aligning the mounting hole 41 of the fixing plate 4 with the threaded hole, the bolt passing through the mounting hole 41 is threaded into the threaded hole, thereby securing the valve body 1 to the energy storage container 5. Figure 9 and Figure 10 As shown, the fire-fighting pipeline 6 is threadedly connected to the inlet 12 and the first outlet 13 of the valve body 1, respectively, for conveying fire-fighting agents. The nozzle 7 is connected to the second outlet 14 of the valve body 1 through the fire-fighting pipeline 6, and the nozzle 7 is installed and connected to the gas fire-fighting interface of the battery pack, thereby guiding the fire-fighting agents to the battery pack in the fault area inside the energy storage container 5.

[0026] This invention features a novel structure and stable operation. In use, the sealing diaphragm 21 of the sealing element 2 faces the valve cavity 11 of the valve body 1. Using a hex wrench, the sealing element 2 is first screwed into the sealing groove 111 until it is completely tightened. Then, the connector 311 of the sleeve 31 is screwed into the mounting groove 15, thereby installing the puncture component 3 onto the valve body 1. The fixing plate 4 is then securely connected to the energy storage container through the mounting hole 41 and fasteners. After the independent installation and fixing of the puncture valve is completed, the inlet 12 and the first outlet 13 are connected to the main fire-fighting pipeline, respectively. The second outlet 14 is connected to the nozzle 7 through the fire-fighting pipeline 6. The nozzle 7 is then installed on the gas fire-fighting interface of the corresponding battery pack, completing the connection between the puncture valve and the fire-fighting pipeline 6. Simultaneously, the puncture valve fixed on the energy storage container 5 also provides support and fixation for the fire-fighting pipeline 6.

[0027] When a fire hazard such as thermal runaway occurs, the puncture component 3 receives an electrical signal and is quickly activated, triggering the puncture needle 32 to slide along the axial direction of the sleeve 31 and penetrate into the valve chamber 11 until the puncture needle 32 punctures the sealing diaphragm 21 of the sealing element 2. At this time, the flow direction of the fire extinguishing agent changes from flowing from the inlet 12 to the first outlet 13 due to the influence of gravity, and then flows from the second outlet 14 to the sprinkler head 7 and is guided by the sprinkler head 7 into the faulty battery pack, thus completing the fire hazard prevention and control.

[0028] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0029] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
