Technical Field
[0001] This utility model relates to the field of puncture valve technology for pressure storage modules, and in particular to a puncture valve for starting a pressure storage module. Background Technology
[0002] In modern energy storage systems, the pressure storage module, as a core component, undertakes the critical task of storing high-pressure fire extinguishing agents or gases. Based on the pressure balance mechanism, under normal conditions, the high-pressure medium is stably sealed inside through a high-strength sealing structure to ensure that the pressure is maintained within a set safe range. The puncture valve, as a key connection device between the pressure storage module and the external environment, plays an important role as a "pressure release switch" in the entire system. After receiving a trigger signal, it punctures the sealing diaphragm, thereby opening the passage between the pressure storage module and the outside, allowing the internal high-pressure medium to be released quickly. Among the existing puncture valves, the linear puncture structure is a widely used type. This structure directly drives the puncture head to move in a straight line through a power source to penetrate the sealing diaphragm.
[0003] In this structure, the piercing head needs to overcome the friction of the guide sleeve throughout the entire stroke, and the force output by the power source needs to continuously cover the entire stroke. When the diaphragm strength is high, the power of the power source needs to be increased to ensure the piercing effect. This not only increases energy consumption, but may also cause the diaphragm to not be pierced completely due to insufficient instantaneous force, resulting in slow media leakage. Utility Model Content
[0004] The present invention addresses the shortcomings of the prior art, which require the power source to continuously cover the entire stroke. When the diaphragm strength is high, the power source power needs to be increased to ensure the puncture effect. This not only increases energy consumption but may also lead to incomplete puncture of the diaphragm due to insufficient instantaneous force, resulting in slow leakage of the medium. The present invention provides a pressure storage module-activated puncture valve, which has the advantages of high force transmission efficiency, low energy consumption, and good puncture effect on high-strength diaphragms, thus solving the problems mentioned in the prior art.
[0005] This utility model provides the following technical solution: a pressure storage module start puncture valve, including a valve body, a partition plate is fixedly installed in the middle of the inner wall of the valve body, the partition plate divides the internal cavity of the valve body into two spaces, and a puncture component and a drive component are provided on the left side of the inside of the valve body;
[0006] The puncture assembly includes a movable rod that is slidably mounted in the middle of the partition plate. A puncture head is fixedly mounted on one right end of the movable rod. A limiting plate is fixedly mounted on the side of the movable rod away from the puncture head. An installation block is fixedly mounted on the other end of the limiting plate. A spherical groove is formed inside the installation block, and a ball bearing is embedded inside the spherical groove.
[0007] The drive assembly includes a servo motor, and a drive rod is mounted on the output end of the servo motor via a coupling. A cam is fixedly mounted on the bottom of the drive rod, and a reset groove is provided on the side away from the cam's protruding end.
[0008] Preferably, the two ends of the movable rod are fixedly installed with limit protrusions, a compression spring is fixedly installed on the side of the limit plate near the partition plate, and the other end of the compression spring is fixedly installed on the surface of the partition plate.
[0009] Preferably, the compression spring is sleeved on the outside of the movable rod, and the internal volume of the spherical groove is larger than the volume of the ball.
[0010] Preferably, a motor box is fixedly installed on the upper left side of the valve body, the servo motor is located inside the motor box, and the output end of the servo motor passes through the bottom of the motor box and is connected to the drive rod.
[0011] Preferably, a sealing assembly is provided in the internal space of the valve body located on the right side of the partition plate. The sealing assembly includes a mounting groove, which is formed in the inner wall of the valve body.
[0012] Preferably, the mounting groove is provided with a diaphragm, the sharp end of the piercing head corresponds to the middle of the diaphragm, the inner wall of the mounting groove is provided with multiple positioning holes, and the side of the diaphragm is provided with multiple mounting bolts.
[0013] Preferably, all of the mounting bolts penetrate the side of the diaphragm and are threaded into the internal parts of the multiple positioning holes.
[0014] Preferably, a feed pipe is fixedly installed at the bottom of the valve body, a threaded connector is fixedly installed at one end of the right side of the valve body, a discharge pipe is threaded onto the surface of the threaded connector, and a nozzle is fixedly installed at the other end of the discharge pipe.
[0015] This utility model has the following advantages:
[0016] 1. By setting up the coordinated operation of the puncture component and the drive component, when the servo motor drives the drive rod to rotate the cam, the cam's protruding end contacts the ball and generates a linear thrust. The ball rotates adaptively in the spherical groove to reduce contact friction, thereby pushing the mounting block, limit plate, and movable rod to slide along the partition plate. The compression spring is simultaneously compressed and deformed. As the cam continues to rotate, its protruding end pushes the movable rod to drive the puncture head to gradually approach and eventually penetrate the diaphragm. By shortening the force energy transmission path, the efficiency of force energy utilization is improved. Effective puncture of high-strength diaphragms can be ensured without increasing the power source power, ensuring rapid release of the medium.
[0017] 2. By setting a compression spring in conjunction with a reset groove, when the cam protrusion rotates and disengages from the ball, the compression spring releases its elastic potential energy, pushing the limit plate, movable rod, and mounting block to move in the opposite direction, causing the piercing head to return to its initial position. At the same time, the ball, under the thrust of the compression spring, embeds itself into the reset groove of the cam, achieving precise positioning of the movable rod and preventing displacement and wobbling in non-working states. This ensures the reliability of the piercing head reset and reduces frictional resistance during the reset process through the cooperation of the ball and the spherical groove, avoiding the problem of jamming in traditional reset structures. It works synergistically with the high-efficiency energy transmission during the piercing stage, improving the overall structural stability and service life. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-2 A pressure storage module-activated puncture valve includes a valve body 1. A partition plate 5 is fixedly installed in the middle of the inner wall of the valve body 1. The partition plate 5 divides the internal chamber of the valve body 1 into two spaces. A puncture component 6 and a drive component 7 are provided on the left side of the inside of the valve body 1.
[0029] Please see Figures 4-5 The puncture assembly 6 includes a movable rod 601, which is slidably mounted in the middle of the partition plate 5. A puncture head 603 is fixedly mounted on one right end of the movable rod 601. A limiting plate 604 is fixedly mounted on the side of the movable rod 601 away from the puncture head 603. An installation block 606 is fixedly mounted on the other end of the limiting plate 604. A spherical groove 607 is provided inside the installation block 606. A ball bearing 608 is embedded inside the spherical groove 607. The ball bearing 608 can rotate flexibly in the spherical groove 607. When the cam 704 rotates and contacts the ball bearing 608, the ball bearing 608 can convert the sliding friction between the cam 704 and the installation block 606 into rolling friction through its own rotation, which significantly reduces the frictional resistance at the contact point between the two.
[0030] Please see Figures 2-4The drive assembly 7 includes a servo motor 702. A drive rod 703 is mounted on the output end of the servo motor 702 via a coupling. A cam 704 is fixedly mounted on the bottom of the drive rod 703. When the servo motor 702 drives the drive rod 703 to rotate the cam 704, the protruding end of the cam 704 contacts the ball 608 and generates a linear thrust. The ball 608 adaptively rotates within the spherical groove 607 to reduce contact friction, thereby pushing the mounting block 606, the limiting plate 604, and the movable rod 601 to slide along the partition plate 5. As the cam 704 continues to rotate, its protruding end pushes the movable rod 601, causing the piercing head 603 to gradually approach and eventually penetrate the diaphragm 403. This shortens the force transmission path and improves the efficiency of force utilization without increasing the dynamic range. With sufficient power, the high-strength diaphragm 403 can be effectively punctured, ensuring rapid release of the medium. A reset groove 705 is provided on the side away from the protruding end of the cam 704. After the movable rod 601 drives the puncture head 603 to reset, the ball 608 is embedded in the reset groove 705 of the cam 704 under the thrust of the compression spring 605, achieving precise positioning of the movable rod 601 and preventing displacement and shaking in the non-working state. This not only ensures the reliability of the puncture head 603 reset, but also reduces the frictional resistance during the reset process through the cooperation of the ball 608 and the spherical groove 607, avoiding the problem of easy jamming in the traditional reset structure. It works synergistically with the high-efficiency energy transmission in the puncture stage, improving the overall structural stability and service life.
[0031] Please see Figures 4-5 Limiting protrusions 602 are fixedly installed at both ends of the movable rod 601. A compression spring 605 is fixedly installed on the side of the limiting plate 604 near the partition plate 5. The other end of the compression spring 605 is fixedly installed on the surface of the partition plate 5. The compression spring 605 is sleeved on the outside of the movable rod 601. By setting the compression spring 605 to cooperate with the reset groove 705, when the protruding end of the cam 704 rotates and disengages from the ball 608, the compression spring 605 releases elastic potential energy, pushing the limiting plate 604, the movable rod 601 and the mounting block 606 to move in the opposite direction, so that the piercing head 603 returns to the initial position. The internal volume of the spherical groove 607 is larger than the volume of the ball 608. A motor box 701 is fixedly installed on the upper left side of the valve body 1. The servo motor 702 is located inside the motor box 701 and the output end of the servo motor 702 passes through the bottom of the motor box 701 and is connected to the drive rod 703.
[0032] Please see Figures 1-3A sealing assembly 4 is provided inside the valve body 1 located on the right side of the partition plate 5. The sealing assembly 4 includes a mounting groove 401, which is formed on the inner wall of the valve body 1. A diaphragm 403 is provided inside the mounting groove 401. The sharp end of the piercing head 603 corresponds to the middle of the diaphragm 403. After the diaphragm 403 is pierced, the high-pressure medium stored in the right chamber of the valve body 1 can directly enter the discharge pipe 32 through the puncture of the diaphragm 403, and then be released to the target area through the nozzle 33. Multiple positioning holes 402 are provided on the inner wall of the mounting groove 401, and multiple mounting bolts 404 are provided on the side of the diaphragm 403. Each mounting bolt 404 penetrates the side of the diaphragm 403 and is threaded into the internal of the multiple positioning holes 402. The diaphragm 403 is detachably fixed in the mounting groove 401 by the mounting bolts 404 penetrating the side and threaded into the positioning holes 402. This ensures that the edge of the diaphragm 403 fits tightly against the inner wall of the mounting groove 401, forming a reliable seal. The bottom of the valve body 1 is fixedly installed with a feed pipe 2. A threaded connector 31 is fixedly installed at one end of the right side of the valve body 1. A discharge pipe 32 is threaded onto the surface of the threaded connector 31. A nozzle 33 is fixedly installed at the other end of the discharge pipe 32.
[0033] Working principle: In actual use, firstly, the high-pressure medium enters the chamber on the right side of the valve body 1 through the feed pipe 2, which is closed by the partition plate 5 and the diaphragm 403, to achieve pre-storage of the medium. When the puncture action needs to be initiated, the servo motor 702 starts and drives the cam 704 to rotate through the drive rod 703. The protruding end of the cam 704 gradually contacts the ball 608.
[0034] As the cam 704 continues to rotate, the protruding end exerts a thrust on the ball 608. The ball 608 rotates adaptively within the spherical groove 607 to reduce contact friction. At the same time, it pushes the mounting block 606, the limiting plate 604, and the movable rod 601 to slide to the right along the guide direction of the partition plate 5. During this process, the limiting plate 604 compresses the compression spring 605, causing it to undergo elastic deformation and store reset potential energy. The movable rod 601 drives the piercing head 603 to move to the right synchronously and gradually approach the diaphragm 403.
[0035] When the cam 704 rotates to the limit position where the protruding end contacts the ball 608, the piercing head 603 penetrates the diaphragm 403 under the thrust of the cam 704. The right chamber of the valve body 1 is connected to the discharge pipe 32. The high-pressure medium is quickly released to the target area through the discharge pipe 32 and the nozzle 33 in sequence, and the piercing action is completed.
[0036] Servo motor 702 drives cam 704 to rotate in the opposite direction. When the protruding end of cam 704 disengages from ball 608, compression spring 605 releases stored elastic potential energy, pushing limit plate 604, movable rod 601 and mounting block 606 to move to the left, causing piercing head 603 to return to its initial position. At the same time, under the thrust of compression spring 605, ball 608 is embedded in the reset groove 705 of cam 704, achieving precise limiting of movable rod 601 and ensuring that piercing head 603 remains stable in non-working state.
