DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with 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 definite definition of the protection scope of the present invention.

[0024] See also Figure 1 As shown, this embodiment discloses a novel 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, wherein the actuation mechanism device 2 is detachably fixed to the inner side 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 to push the actuating piston 22 to close so that the medium release channel 51 and the cylinder body 21 are closed. After reaching the opening and closing threshold of the actuating check valve 23, the high-pressure medium opens the actuating check valve 23 and flows into the high-pressure medium container 1.

[0029] When the excitation device is released, the excitation device 4 starts, the actuating piston 22 (pushes the actuating piston through 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, the actuating mechanism body 20 is provided with 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.

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 mouth device 3, and 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, and can be made of metal or composite materials. The high-pressure medium container 1 can be a single cylinder, a cuboid, 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 fixed to the inner side of the high-pressure medium container 1 by means of thread, snap or riveting. The size of the medium release channel 51 is determined by calculation to match the expansion capacity of the high-pressure medium. The medium release channel 51 can be a single circular, square, or special-shaped one, 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 arranged on the wall of the high-pressure medium container 1, and the actuating mechanism device 2 and the filling port device 3 are connected to the flow channel. It is used to fill the high-pressure medium and has the functions of sealing and one-way filling. The filling port device 3 can be a metal part, an alloy part, or a composite material part. The filling port device 3 can be connected to the wall of the high-pressure medium container by threading, riveting, or snapping.

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

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

[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, volumes, sizes, configurations, and performance-related information.

[0042] According to the work capacity requirements, match the high-pressure medium flow channel, the opening and closing pressure of the actuating check 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 passes through the first flow channel 24 in turn, and enters the second flow channel 25 inside the actuating mechanism device 2 from the annular first flow channel 24. After the high-pressure medium enters the third flow channel 26, because the actuating check valve 23 has a certain opening and closing pressure, the high-pressure medium first pushes the actuating piston 22 to close, closes the release port device flow channel, and forms 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 to enter the fourth flow channel 27, and finally fills the high-pressure medium container and the fifth flow channel 28.

[0045] The actuating piston remains closed when filling with high-pressure medium under 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 pressure in the flow channel, 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 means of a 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 needs, 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, so that the pressure in the third flow channel 26 quickly approaches 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 at 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 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 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, has accurate pressure release, and a rapid and controllable release process. In particular, it can be repeatedly filled and released for use, 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, and can be used in some scenarios with strict restrictions on device quality.

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