Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure medium release triggering, and more particularly to a novel high-pressure medium release actuating device and a method of using the same. Background Art

[0002] Currently, the use of high-pressure medium expansion to generate work has become widespread due to its unique advantages, including low thermal signature, low cost, and environmental friendliness. Applications include gas blasting, inflatable rescue, and load propulsion. High-pressure medium expansion uses a sealed release mechanism. This mechanism works by increasing the pressure of the high-pressure medium within a sealed container to a certain threshold, then rupturing and releasing it, allowing the high-pressure medium to expand and generate work externally. Release mechanisms for high-pressure medium sealed containers generally require good sealing, high reliability, simple structure, easy operation, accurate release pressure, a fast and controllable release process, and reusability. Currently, the commonly used trigger-release rupture diaphragm is simple in design but suffers from drawbacks such as inaccurate release pressure and non-reusability. Solenoid valve release mechanisms offer precise control and direct-flow valves, but their complex structure and high mass pose significant limitations in applications with strict quality requirements. Manual direct-flow release mechanisms offer simple structure and high reliability, but lack electrical triggering, making them difficult to integrate with the system. Summary of the Invention

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described in detail below with reference to 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.

[0024] See Figure 1 As shown, this embodiment discloses a new type of high-pressure medium release actuation device, including a high-pressure medium container 1, an actuation mechanism device 2, a filling mouth device 3, an excitation device 4 and a release mouth device 5, and the actuation mechanism device 2 is detachably fixed to the inner side of the high-pressure medium container 1.

[0025] The release port device 5 is connected to the inner side of the high-pressure medium container 1 and is connected to the actuating mechanism device 2 . The release port device 5 is provided with a medium release flow channel 51 .

[0026] The filling port device 3 and the excitation device 4 are both provided on the side wall of the high-pressure medium container 1 .

[0027] The actuating mechanism device 2 includes an actuating mechanism body 20, a cylinder body 21 arranged in the actuating mechanism body 20, and an actuating piston 22 arranged in the cylinder body 21. The first end of the cylinder body 21 is connected to the medium release flow channel 51, and the second end of the cylinder body 21 is connected to the inner cavity of the high-pressure medium container 1 through an actuating one-way valve 23 (the actuating one-way valve 23 controls the opening and closing and connection of the flow channel through a certain pressure). The filling mouth device 3 and the excitation device 4 are both connected to the second end of the cylinder body 21.

[0028] When the high-pressure medium is filled, the high-pressure medium enters the second end of the cylinder body 21 through the filling port device 3 and pushes the actuating piston 22 to close, so that the medium release flow channel 51 and the cylinder body 21 are closed. After reaching the opening and closing threshold of the actuating one-way valve 23, the high-pressure medium opens the actuating one-way valve 23 and flows into the high-pressure medium container 1.

[0029] When the excitation device is released, the excitation device 4 is started, the actuating piston 22 (which is pushed by the flow of the medium to control the opening and closing of the mouth flow channel of the release mouth device 5) moves and opens the medium release flow channel 51 of the release mouth device 5 and the cylinder body 21, and the high-pressure medium is released through the medium release flow channel 51.

[0030] In this embodiment, a first flow channel 24, a second flow channel 25, a third flow channel 26, a fourth flow channel 27 and a fifth flow channel 28 are provided in the actuating mechanism body 20. The filling mouth device 3 and the excitation device 4 both communicate with the second flow channel 25 through the first flow channel 24. The second end of the cylinder body 21 is connected to the actuating one-way valve 23 through the third flow channel 26. The actuating one-way valve 23 is connected to the inner cavity of the high-pressure medium container 1 through the fourth flow channel 27. The fifth flow channel 28 connects the inner cavity of the high-pressure medium container 1 with the first end of the cylinder body 21.

[0031] Preferably, the first flow channel 24 is an annular flow channel.

[0032] Preferably, before the high-pressure medium container 1 is used, the high-pressure medium is filled into the inner cavity of the high-pressure medium container 1 through the filling port device 3. The high-pressure medium can also be stored in the inner cavity of the high-pressure medium container 1 for a long time. According to the calculation results of the required expansion work of the high-pressure medium, the high-pressure medium container is calculated to match the work expansion capacity. The volume of the high-pressure medium container 1 can range from tens of milliliters to tens of liters, or even tens of cubic meters. It can be made of metal or composite materials. The high-pressure medium container 1 can be a single cylinder, a rectangular parallelepiped, a capsule or a special-shaped body.

[0033] Preferably, the actuating mechanism device 2 is made of metal, alloy or composite material, and the actuating mechanism device 2 is fixed to the inner side of the high-pressure medium container 1 by means of threads, snaps or rivets.

[0034] Preferably, the release port device 5 is made of metal, alloy, or composite material and is secured to the inside of the high-pressure medium container 1 via threads, snaps, or rivets. The size of the medium release channel 51 is determined based on calculations to match the expansion capacity of the high-pressure medium. The medium release channel 51 can be a single circular, square, or irregularly shaped shape, or a combination of multiple shapes.

[0035] Preferably, a container sealing ring 52 is provided between the release port device 5 and the inner side of the high-pressure medium container 1 to prevent leakage of the high-pressure medium.

[0036] Preferably, a piston sealing ring 29 is provided between the actuating piston 22 and the cylinder body 21 .

[0037] Preferably, the filling port device 3 is mounted on the wall of the high-pressure medium container 1, with the actuating mechanism 2 and the filling port device 3 interfacing with the flow channel. This device is used for filling the high-pressure medium and provides sealing and one-way filling. The filling port device 3 may be made of metal, alloy, or composite material. It may be connected to the high-pressure medium container wall via threads, rivets, or snap fasteners.

[0038] Preferably, the excitation device 4 is disposed on the wall of the high-pressure medium container 1, and the actuating mechanism 2 and the excitation device 4 are connected to the flow channel. By controlling the opening and closing of the excitation device 4, the actuating mechanism is activated and controlled to move, thereby releasing the high-pressure medium. The excitation device 4 can be a chemical and pharmaceutical product device, or an electric or electromagnetic heating device.

[0039] The method of using a novel high-pressure medium release actuation device of the present invention includes a method of using the high-pressure medium filling method and a method of using the excitation device 4 to release the device, which are described below respectively.

[0040] The method and operating principle of high-pressure medium filling in the present invention are as follows:

[0041] According to scenario calculations and requirements, select or customize matching high-pressure medium container materials, volume, size, configuration and performance-related information.

[0042] According to the work performance requirements, match the high-pressure medium flow channel, the opening and closing pressure of the actuating one-way valve, the opening and closing pressure of the actuating piston, and the relevant parameters of the release port.

[0043] The high-pressure medium container is filled with high-pressure medium through the one-way valve of the filling port device.

[0044] The high-pressure medium sequentially passes through the first flow channel 24, then enters the second flow channel 25 inside the actuator device 2. After entering the third flow channel 26, the high-pressure medium first pushes the actuator piston 22 to close because the actuating check valve 23 has a certain opening and closing pressure, sealing the release port device flow channel and forming a closed container. As the filling pressure rises and reaches the opening and closing threshold of the actuating check valve 23, the high-pressure medium immediately pushes the actuating check valve 23 open and enters the fourth flow channel 27, ultimately filling the high-pressure medium container and the fifth flow channel 28.

[0045] The actuating piston remains closed when filled with high-pressure medium under the action of uneven pressure.

[0046] When the filling and loading reaches a predetermined pressure, the pressure in the high-pressure medium container 1 is close to equilibrium with the flow channel pressure, and the one-way actuating valve 23 closes the interface between the fourth flow channel 27 and the flow channel under the action of the threshold pressure.

[0047] The pressure in the high-pressure medium container 1 is recorded in real time by the test instrument.

[0048] Release according to experimental instructions.

[0049] The release method and operating principle of the excitation device 4 in the present invention are as follows:

[0050] Do a good job in protecting personnel and equipment and clean up the venue.

[0051] Make preparations for opening and releasing the high-pressure medium valve.

[0052] Confirm that the signal connection line of the excitation device 4 is connected to the excitation control device.

[0053] According to the excitation requirement, the excitation device 4 is started and the mouth of the excitation device is opened.

[0054] The pressure in the annular first flow channel 24 decreases rapidly, thereby causing the pressure in the second flow channel 25 to decrease accordingly, resulting in the pressure in the third flow channel 26 quickly approaching the external environmental pressure.

[0055] The movement of the actuating piston 22 is controlled by the pressure of the high-pressure medium in the fifth flow channel 28 and the pressure in the third flow channel 26. After excitation, the pressure in the third flow channel 26 drops rapidly, resulting in an imbalance in the pressure of the two sections of the actuating piston. Under the action of the high-pressure medium pressure in the fifth flow channel 28, the actuating piston 22 is pushed to open, thereby opening the flow channel at the mouth of the release device.

[0056] The medium in the high-pressure medium container is quickly released to the medium release flow channel 51 through the fifth flow channel 28 .

[0057] The actuation mode of the present invention is simple and clear, safe and reliable, and can be widely used in the fields of gas blasting, inflation rescue, load propulsion, etc.

[0058] The invention is easy to operate, releases pressure accurately, and has a rapid and controllable release process. In particular, it can be repeatedly filled and released, and has broad market application prospects.

[0059] The structure of the present invention is clear, simple and reliable, and can be processed and designed using some composite lightweight materials. It can be used in some scenarios with strict restrictions on device quality.

As long as they do not exceed the scope of protection described in the claims of the present invention, they should be within the scope of protection of the present invention.
