Description

Technical Field

[0001] This invention patent relates to the field of ultra-high-speed launch technology, specifically to a high-pressure gas release valve structure for a light gas gun and its usage method. Background Technology

[0002] The development of spacecraft meteorite protection, high-pressure physics, and kinetic energy weapons all require research into hypervelocity projectile propulsion technology. Light gas cannons, capable of launching projectiles of various shapes and sizes, and adaptable to a wide range of materials, are among the most widely used technologies for hypervelocity projectile propulsion. The main body of a light gas cannon consists of a launch tube, a high-pressure gas chamber, and a release mechanism. Its principle is to use the expansion of high-pressure gas to accelerate and launch the projectile. The high-pressure gas chamber is a crucial component of the gas-driven light gas cannon; high-pressure gas is injected through high-pressure cylinders or compressors and stored for later launch.

[0003] The high-pressure chamber of a light gas cannon usually contains a high-pressure gas release structure. The speed of the release mechanism determines the magnitude of the projectile's acceleration. If the release mechanism is slow, a lot of energy will be lost during the gas release process, and the subsequent gas-driven projectile pressure and time will drop sharply. Therefore, the difficulty and key point in the design of the high-pressure chamber of a light gas cannon is the opening speed of the release structure.

[0004] Currently, the release mechanisms of gas-driven light gas cannons typically employ two types: piston-type and diaphragm-breaking release mechanisms. Traditional piston-type release mechanisms usually require a large piston and cylinder to generate sufficient force, increasing the overall weight of the light gas cannon and affecting operational convenience. Furthermore, their complex structure requires space to accommodate the piston and cylinder. The release mechanism also involves components such as the piston, cylinder, and hydraulic seals, requiring regular inspection and maintenance to ensure normal operation, increasing maintenance costs and workload. Most importantly, the energy conversion efficiency is low due to the limitation of the piston valve opening speed, making it difficult to drive projectile velocities exceeding 1000 m / s. On the other hand, simple diaphragm-breaking release mechanisms require diaphragms of varying thicknesses for firing projectiles of different weights and velocities. The diaphragm-breaking device and operation are complex, impacting testing efficiency and costs when high-frequency testing is required.

[0005] Therefore, the present invention aims to design and provide a high-pressure gas release valve structure for a light gas cannon and its usage method, in order to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a high-pressure gas release valve structure and its usage method for a light gas gun. The high-pressure gas release valve structure designed in this invention integrates two release mechanisms, which can be used for both ultra-high-speed launch tests and high-frequency launch tests. It can be used to test the penetration performance of a single projectile as well as the penetration effect of multiple tests, thus improving test efficiency. At the same time, this release valve structure optimizes the traditional valve structure, enabling the valve opening speed to reach the millisecond level, meeting the requirements of high-frequency light gas gun tests. Furthermore, the overall structure is simple, easy to manufacture, and has good versatility and scalability.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. This invention combines a membrane-breaking release mechanism with a cone valve release mechanism. It can achieve ultra-high-speed launch of projectiles using a membrane-breaking release mechanism, and improve test efficiency using a cone valve release mechanism to meet the needs of more test scenarios. At the same time, both the high-pressure gas chamber mechanism and the release mechanism adopt a mechanical quick assembly method, which is convenient for installation and disassembly. This allows for faster installation of dual pistons, and the structure is easy to assemble and disassemble. It also avoids the trouble of overall disassembly and assembly due to flaw detection and repair.

[0029] 2. In order to ensure safety during the launch operation using the release valve structure, the present invention employs a software remote control mechanism to control the opening of the solenoid valve in the release valve structure. This can be adapted to launch modes with single pump tubes and dual pump tubes, and is simple and reliable to operate.

[0030] 3. The high-pressure gas release valve structure designed in this invention integrates two release mechanisms. It can use both a cone valve release mechanism and a rupture membrane release mechanism to release the high-pressure gas in the high-pressure chamber. This allows for a faster launch time and the release mechanism can be adjusted according to the actual test conditions to improve test efficiency. In addition, the release valve structure has a serrated thread reserved at the external connection of the high-pressure chamber shell. The cone valve release mechanism in the chamber is threaded to the chamber shell, and it can also be extended to connect other structures.

[0031] 4. The high-pressure gas release valve structure designed in this invention is easy to install, process, and assemble. It also adopts a more efficient self-excited fast cone valve release mechanism, which has a shorter opening time than conventional piston release mechanisms, controllable within 3ms. This results in a higher instantaneous load on the projectile, leading to a higher launch speed and meeting the requirements of ultra-high-speed launch impact tests. The release mechanism has a complete structure, thus ensuring launch safety. Through the structural dimension matching of the threaded and screw connection mechanism, it can adapt to valves of various lengths and masses, exhibiting good versatility and expandability.

The high-pressure gas chamber mechanism 2 is protected and fixed by a gas chamber fixing half cover 8. The hoop 6 is used to fix the high-pressure gas chamber mechanism 2 to the gas chamber base 1. The open end of the high-pressure gas chamber mechanism 2 is detachably connected to a cone valve type release mechanism 3 via a sawtooth thread. An O-ring is fixedly installed between the open end of the high-pressure gas chamber mechanism 2 and the cone valve type release mechanism 3 to increase the sealing between the two. The specific Shore hardness of the O-ring is 90. The cone valve type release mechanism 3 is detachably connected to a diaphragm-breaking release mechanism 4. The diaphragm-breaking release mechanism 4 is detachably connected to a firing mechanism 5.

[0042] The high-pressure gas chamber mechanism 2 includes a gas chamber housing 201, a safety relief valve 202, a solenoid valve, and multiple sensors. The gas chamber housing 201 is a hollow structure with a volume of 15L, an inner diameter of 200mm, and a cavity length of 480mm. The gas chamber housing 201 is connected to the gas chamber base 1. The safety relief valve 202 is fixedly installed at the bottom of the gas chamber housing 201 and communicates with the gas chamber cavity. The safety relief valve 202 is set to a pressure of 35MPa. The side of the gas chamber housing 201 is provided with an air injection hole and multiple mounting holes. The solenoid valve is fixedly installed in the air injection hole. The thread specification of the air injection hole is M22×1.5, the thread specification of the temperature measurement hole is M30×3.5, and the thread specification of the other holes is M20×1.5. Multiple sensors are fixedly installed on the mounting holes.

[0043] The cone valve release mechanism 3 includes a cone valve release mechanism housing 301, a piston valve body 302, a guide valve 303, a buffer cylinder wall 304, a cone valve vent pipe, a sliding piston 305, a piston rod 306, and a plug 307. The cone valve release mechanism housing 301 has an irregular coaxial through-hole structure, including a large-diameter hole and a small-diameter hole. The cone valve release mechanism housing 301 is connected to the outlet of the air chamber housing 201. The piston valve body 302 is fixedly installed inside the cone valve release mechanism housing 301. The guide valve 303 and the buffer cylinder wall 304 are respectively installed on the piston valve body 305. At the two opposite ends of 02, the guide valve 303 is close to the air chamber housing 201, and the buffer cylinder wall 304 is away from the air chamber housing 201. The piston valve body 302 has a piston chamber inside, which is connected to the guide valve 303. The sliding piston 305 is installed in the piston chamber. The cone valve vent pipe is installed on the small diameter orifice wall. High-pressure gas enters the piston chamber through the cone valve vent pipe, pushing the piston rod 306 forward. One end of the cone valve vent pipe is connected to the piston chamber and is located on the side of the sliding piston 305 close to the air chamber housing 201. The other end of the cone valve vent pipe passes through the cone valve. The release mechanism housing 301 is located outside the release mechanism housing. One end of the piston rod 306 is fixedly connected to the sliding piston 305, and the other end of the piston rod 306 passes through the end of the piston valve body 302 and is fixedly connected to the plug 307. The plug 307 is frustoconical in shape. The plug 307 forms a seal with the conical surface of the outlet of the cone valve type release mechanism 3. The higher the pressure, the better the sealing performance, solving the problem of frequent installation of sealing rings in traditional pistons. The plug 307 is located inside the buffer cylinder wall 304, and the size of the plug 307 matches the inner wall size of the buffer cylinder wall 304. To prevent the plug 307 from rebounding and directly impacting the cone valve release mechanism 3; the main process is that when the release valve structure is launched, the cone valve venting pipeline is released, and the air pressure at the bottom of the sliding piston 305 is released instantly. The piston rod 306 drags the plug 307 backward. The overall opening time is within 3ms, realizing the rapid release of high-pressure gas. When the plug 307 moves backward rapidly, and the tail of the plug 307 enters the buffer chamber formed by the buffer cylinder wall 304, the gas in the buffer chamber is compressed and generates high pressure, which can prevent the valve body from rebounding and directly impacting the release mechanism.

[0044] The membrane-breaking release mechanism 4 includes a membrane-breaking release mechanism housing 401, a membrane clamping ring 402, two diaphragms 403, and a membrane-breaking venting pipeline. The membrane clamping ring 402 is sleeved on and fixedly connected to the outer wall of the membrane-breaking release mechanism housing 401. The membrane clamping ring 402 is connected to the cone valve release mechanism housing 301. The two diaphragms 403 are made of aluminum alloy or stainless steel according to different injection pressures. The central part is engraved with cross grooves of different depths, which are fixedly connected to the two ends of the membrane-breaking release mechanism housing 401. The cross grooves allow the diaphragms 403 to be stretched and broken from the grooves without producing fragments. The diameter of both diaphragms 403 is larger than the diameter of the inner cavity of the membrane-breaking release mechanism housing 401. To ensure that the central rupture circle area of ​​the diaphragm 403 is larger than the cross-sectional area of ​​the inner cavity of the rupture release mechanism housing 401, so that the projectile can obtain the maximum acceleration, one end of the rupture vent pipe passes through the rupture release mechanism housing 401 and is connected to its cavity, and the other end of the rupture vent pipe passes through the clamping ring 402 and is located outside the rupture release mechanism 4. The main process is that when the release valve structure is launched, air is pre-injected so that the air pressure in the cavity of the rupture release mechanism housing 401 is half of the air pressure in the cavity of the high pressure air chamber housing 201. When launched, the pressure in the cavity of the rupture release mechanism housing 401 is released, and the two diaphragms 403 rupture in sequence to release high pressure gas into the firing barrel 502 to drive the projectile.

[0045] The firing mechanism 5 includes a gun barrel, a gun barrel connecting flange 503, and multiple gun barrel connecting screws 504; the multiple gun barrel connecting screws 504 are fixedly installed on the gun barrel connecting flange 503, the gun barrel connecting flange 503 is sleeved on the outer wall of the gun barrel and fixedly connected thereto, and the gun barrel connecting screws 504 are threadedly connected to the cone valve release mechanism housing 301.

[0046] The firing mechanism 5 includes a barrel housing 501, a firing barrel 502, a barrel connecting flange 503, and multiple barrel connecting screws 504.

The barrel connecting flange 503 is sleeved on the outer wall of the barrel housing 501 and fixedly connected to it. The barrel connecting screws 504 are threadedly connected to the cone valve release mechanism housing 301.

[0047] The valve opening structure is also electrically connected to a remote control mechanism. The remote control mechanism includes a control panel and a compressor. The compressor is connected to the rupture venting line and the cone valve venting line, respectively. The control panel is electrically connected to the compressor, the solenoid valve, and the sensor, respectively. The remote control mechanism can obtain information about the cavity of the valve opening structure in real time and control the opening and closing of the solenoid valve in the venting line using the control panel. This is used to adapt to different launch functions and ensure the safety of the launch process.

[0048] In this preferred embodiment, the outer wall of the gas chamber housing 201 is fixedly provided with threads, and the flange is installed on the threads to increase the strength of the high-pressure gas chamber structure.

[0049] Example 2: A method of using a high-pressure gas release valve structure for a light gas cannon, comprising the following steps:

[0050] S1. Preset the intracavitary pressure values, time parameters and related data of the cone valve release mechanism 3 and the rupture membrane release mechanism 4 through the control panel, and generate control signals;

[0051] S2. The control panel transmits control signals to the compressor, thereby controlling the compressor to operate and continuously inject the corresponding high-pressure gas into the cavity of the cone valve release mechanism 3 and the rupture membrane release mechanism 4. The sensor generates an electrical signal based on the change of the current cavity gas pressure and related information and transmits it to the control panel.

[0052] S3. The control panel receives the electrical signal from the sensor and analyzes the real-time air pressure and related data of the cone valve release mechanism 3 and the membrane rupture release mechanism 4, and determines whether the initial preset value has been reached. If not, it returns to step S2; if it has been reached, it executes step S4.

[0053] S4. Generate an end command to automatically control the compressor to stop operating and maintain the pressure state in the chambers of the cone valve release mechanism 3 and the ruptured membrane release mechanism 4.

[0054] S5. The solenoid valves in the cone valve venting line and the diaphragm rupture venting line are opened by controlling the control panel respectively. When the cone valve venting line is opened, the air pressure at the bottom of the sliding piston 305 is released instantly, and the piston rod 306 drags the plug 307 backward. The overall opening time is within 3ms, realizing the rapid release of high-pressure gas. When the diaphragm rupture venting line is opened, the air pressure in the cavity of the diaphragm rupture release mechanism housing 401 is pre-injected so that the air pressure in the cavity of the high-pressure gas chamber housing 201 is half of that in the cavity of the high-pressure gas chamber. When firing, the pressure in the cavity of the diaphragm rupture release mechanism housing 401 is released, and the two diaphragms 403 rupture in sequence to release high-pressure gas into the firing barrel 502 to drive the projectile.

When the cone valve ventilation line is opened, the air pressure at the bottom of the sliding piston (305) is released instantly, and the piston rod (306) drags the plug (307) to move backward. The overall opening time is within 3ms, realizing the rapid release of high pressure gas. When the diaphragm rupture ventilation line is opened, the air pressure in the cavity of the diaphragm rupture release mechanism housing (401) is pre-injected so that the air pressure in the cavity of the high pressure gas chamber housing (201) is half of that in the cavity of the high pressure gas chamber. When firing, the pressure in the cavity of the diaphragm rupture release mechanism housing (401) is released, and the two diaphragms (403) rupture in sequence to release high pressure gas into the firing barrel (502) to drive the projectile.
