Description

Technical Field

[0001] The present invention relates to the technical field of gas supply and transmission pipeline systems for precision instruments, and in particular to a gyro suspension angle device and a gas delivery system. Background Art

[0002] Many precision instruments are very sensitive to external interference such as vibration during operation. However, during operation, precision instruments require air source equipment such as suction vacuum pumps or high-pressure compressors to continuously provide them with power air, and the power air source is often the main source of vibration interference.

[0003] In the prior art, in order to reduce the interference and vibration caused by the power gas source, it is necessary to use a flexible metal tube to transmit the power gas source to minimize and block the vibration of the power gas source. However, in actual applications, due to environmental factors such as the installation space and installation location, the flexible metal tube cannot always be installed and arranged in a straight line. It will have some corners depending on the installation environment. At the corners, the gas flow direction in the flexible metal tube changes. When the gas changes its flow direction, it will exert a lateral thrust on the flexible metal tube, causing the flexible metal tube to easily jump. This problem is particularly obvious when the pressure and flow rate of the transmitted gas change, which is quite detrimental to the operation of precision instruments.

[0004] Therefore, the present invention proposes a gyro suspension corner device and a gas delivery system, aiming to achieve both rigid support and vibration reduction for the transmission pipeline at the corner. Summary of the Invention

[0021] Another object of the present invention is to provide a gas delivery system that can not only deliver power gas to precision instruments, but also effectively reduce the vibration transmitted to the precision instruments at corners and non-corners.

[0022] To achieve this object, the present invention adopts the following technical solutions:

It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation.

[0036] This embodiment provides a gyroscopic suspension angle rotation device, which is mainly suitable for the power gas source transmission system of precision instruments. For example, in the pipeline layout of the gas processing system of the mixed gas of helium-3 and helium-4 in the ultra-low temperature system, the use of this gyroscopic suspension angle rotation device can not only complete the change of the direction of the gas transmission pipeline at the corner, but also avoid the local pipeline bounce problem caused by the use of flexible metal pipes at the corner, and at the same time has the effect of reducing vibration.

[0037] Specifically, if Figure 1 and Figure 2 As shown, the gyro suspension angle device includes a support member 100, a first flange 210, a rigid bent pipe 300, a first gyro suspension 410 and a first cable 510. The support member 100 can be fixed on the rigid surface 20. The first flange 210 is fixed on the support member 100 and is used to connect the first air pipe 11. The rigid bent pipe 300 includes a first pipe section 310 and a second pipe section 320 connected at a 90° angle. The first pipe section 310 is connected to the first flange 210, and the second pipe section 320 is used to connect to the second air pipe 32. The first gyro suspension 410 is installed on the support member 100. One end of the first cable 510 is fixed to the first gyro suspension 410, and the other end is fixed to the rigid bent pipe 300.

[0038] In practical applications, the gyro suspension corner device is positioned at a corner, and the support member 100 is secured to a rigid surface 20, such as a wall. The rigid curved tube 300 is tightened and secured using the first cable 510, the first gyro suspension 410, and the support member 100, effectively achieving a change in direction of the gas delivery pipeline at the corner. Furthermore, the use of a rigid curved tube 300 at the corner of the gyro suspension corner device avoids the problem of using a flexible metal tube at the corner, namely, localized vibration of the flexible metal tube due to the lateral thrust exerted by the gas. This, in turn, prevents vibration of the gas delivery pipeline at the corner caused by the use of a flexible metal tube. Again, some vibrations of the gas flowing between the first pipe section 310 and the first air pipe 11 are transmitted to the support 100 through the first flange 210. Among the vibrations transmitted to the support 100, a part of the vibrations is transmitted to the rigid surface 20 through the support 100, thereby reducing this part of the vibrations, and the other part of the vibrations is transmitted to the first gyro suspension 410 through the support 100. The vibrations transmitted to the first gyro suspension 410 are transmitted to the rigid bend 300 through the first cable 510. The elastic deformation of the flexible material of the first cable 510 itself is used to reduce the vibrations, thereby reducing the vibrations transmitted to the rigid bend 300 by the first cable 510, thereby achieving the effect of reducing the vibrations.

[0039] Optionally, the support member 100 is a plate-shaped structure. Of course, in other embodiments, the support member 100 may also be a support structure such as a support frame.

[0040] Optionally, the first cable 510 is a steel cable. Of course, in other embodiments, the first cable 510 may also be any one or more combinations of steel strands, steel cables, and steel cables.

[0041] Optionally, the rigid elbow 300 is made of stainless steel. Stainless steel has a low thermal conductivity, which prevents heat transfer from the external environment to the gas within the rigid elbow 300. Furthermore, the stainless steel surface is relatively clean, preventing contamination of the transported gas and thus ensuring the purity of the transported gas. It should be noted that 90° right-angle stainless steel tubes are a common standard component, and their specific manufacturing process is a mature existing technology and will not be described in detail here.

[0042] Alternatively, as Figure 1 and Figure 2 As shown, the gyro suspension angle device provided in this embodiment also includes a first bellows 610, one end of the first bellows 610 is connected to the first pipe section 310, and the other end is sealed with the first flange 210 to achieve communication between the first pipe section 310 and the first air pipe 11 through the first bellows 610. The setting of the first bellows 610 can effectively reduce the vibration transmitted from the first air pipe 11 to the first pipe section 310 (or, from the first pipe section 310 to the first air pipe 11).

[0043] Alternatively, as Figure 1 and Figure 2 As shown, the gyro suspension angle device provided in this embodiment further includes a second flange 220 , and the second pipe section 320 can be connected to the second air pipe 32 through the second flange 220 , thereby achieving communication between the second pipe section 320 and the second air pipe 32 .

[0044] Further, if Figure 1 and Figure 2 As shown, the gyro suspension angle device provided in this embodiment also includes a second gyro suspension 420 and a second cable 520. The second gyro suspension 420 is mounted on the second flange 220. One end of the second cable 520 is fixed to the second gyro suspension 420, and the other end is fixed to the rigid bend 300. The provision of the second cable 520 and the second gyro suspension 420 increases the force acting to tighten the rigid bend 300, thereby improving the stability and reliability of the rigid bend 300. Furthermore, the elastic deformation capability of the flexible material of the second cable 520 can reduce some vibration. Even if some vibration is transmitted to the second flange 220 through the second cable 520, this vibration is relatively small.

[0045] Optionally, the second cable 520 is a steel cable. Of course, in other embodiments, the second cable 520 may also be any one or more combinations of steel strands, steel cables, and steel cables.

[0046] Preferably, if Figure 1 and Figure 2 As shown, the first cable 510 is connected to the second pipe section 320, and the second cable 520 is connected to the first pipe section 310, that is, the first cable 510 and the second cable 520 are respectively fixed at two different positions of the rigid bend 300, and the first cable 510 and the second cable 520 are set at an angle, so that the tensioning support positions provided by the first cable 510 and the second cable 520 for the rigid bend 300 are two different positions, thereby improving the stability and reliability of the first cable 510 and the second cable 520 in tightening and fixing the rigid bend 300. On the other hand, this structural setting enables the first gyro suspension 410, the second gyro suspension 420, the first cable 510 and the second cable 520 to jointly form a gyro structure, that is, the first cable 510 and the second cable 520 each have a certain degree of flexibility, and there is also a certain restraining effect between the two. While achieving the tightening and fixing of the rigid bend 300, when the rigid bend 300 shakes, the interaction between the first cable 510 and the second cable 520 can effectively reduce the shaking amplitude of the rigid bend 300, so that it can be maintained in a relatively balanced and stable state, thereby achieving the effect of reducing the vibration of the transmitted gas.

[0047] Further, if Figure 1 and Figure 2 As shown, the first cable 510 is coaxially arranged with the axis of the first pipe section 310, and the second cable 520 is coaxially arranged with the axis of the second pipe section 320, so that the tensioning force provided by the first cable 510 and the second cable 520 to the rigid bend 300 is relatively uniform, and can also effectively improve the mutual restraint effect between the first cable 510 and the second cable 520, which can further improve the stability of the rigid bend 300 and thereby reduce the vibration of the transmitted gas.

[0048] Alternatively, as Figure 1 and Figure 2 As shown, the first gyro suspension 410 is a first gate frame, comprising two first support frames and a first connecting frame connected between the two first support frames. The two first support frames are both mounted on the support member 100, and the first cable 510 is fixed to the middle of the first connecting frame. The second gyro suspension 420 is a second gate frame, comprising two second support frames and a second connecting frame connected between the two second support frames. The two second support frames are both mounted on the second flange 220, and the second cable 520 is fixed to the middle of the second connecting frame. The first and second gyro suspensions 410, 420 are both configured as gate frames, providing good support stability, thereby enhancing the effectiveness of the first and second cables 510, 520 in tightening and securing the rigid bend 300.

[0049] Preferably, if Figure 1 and Figure 2 As shown, the first gyro suspension 410 and the second gyro suspension 420 are arranged in a cross shape and are not connected to each other, which facilitates the assembly of the first gyro suspension 410 and the second gyro suspension 420. At the same time, the separate structural design allows the first gyro suspension 410 and the second gyro suspension 420 to not interfere with each other. When one of the brackets shakes, the other bracket can still maintain a relatively stable state, thereby reducing the shaking of the rigid bend 300 to a certain extent.

[0050] Alternatively, as Figure 1 and Figure 2 As shown, the gyro suspension angle device provided in this embodiment also includes a second bellows 620, one end of the second bellows 620 is connected to the second pipe section 320, and the other end is sealed with the second flange 220 to achieve communication between the second pipe section 320 and the second air pipe 32 through the second bellows 620. The setting of the second bellows 620 can effectively reduce the vibration transmitted from the second pipe section 320 to the second air pipe 32 (or, from the second air pipe 32 to the second pipe section 320).

[0051] The gyro suspension angle device provided in this embodiment cleverly combines rigid and flexible connections, not only resolving the localized vibration problem at corners caused by the use of flexible metal tubes in the prior art, but also achieving multiple vibration reduction effects during power gas transmission through the first bellows 610, the first cable 510, the second bellows 620, and the second cable 520. Furthermore, the arrangement of the first gyro suspension 410, the second gyro suspension 420, the first cable 510, and the second cable 520 enables the rigid curved tube 300 to maintain a relatively stable suspension state, thereby reducing vibrations in the transmitted gas. The gyro suspension angle device provided in this embodiment has a significant vibration reduction effect and is highly flexible and reliable in pipeline layout. When large pressure or airflow fluctuations occur in the pipeline, the gyro suspension angle device can effectively reduce the vibrations caused by these fluctuations. Its novel overall structure makes it suitable for widespread use.

[0052] This embodiment also provides a gas delivery system that can not only deliver power gas to precision instruments, but also effectively reduce the vibration transmitted to the precision instruments at corners and non-corners. Figure 3 As shown, the gas delivery system includes a vibration reduction platform 31, an air source device 10, a first air pipe 11, a second air pipe 32 and the above-mentioned gyro suspension angle device. The vibration reduction platform 31 is used to install the precision instrument 30. The air inlet of the precision instrument 30 is connected to the second pipe section 320 of the gyro suspension angle device through the second air pipe 32. The air outlet of the air source device 10 is connected to the first pipe section 310 of the gyro suspension angle device through the first air pipe 11. The support member 100 of the gyro suspension angle device can be fixed on the rigid surface 20.

[0053] Furthermore, the first air pipe 11 and the second air pipe 32 are both flexible metal pipes. The flexible metal pipes have good softness, and thus can reduce part of the vibration transmitted from the air source equipment 10 to the first pipe section 310, and part of the vibration transmitted from the second pipe section 320 to the precision instrument 30. On the basis of reducing the vibration of the gyro suspension angle device, further reduction of vibration is achieved.

[0054] Optionally, the flexible metal tube may be a stainless steel hose, a metal bellows, or the like.

[0055] The following is a brief description of the working principle of the gas delivery system provided in this embodiment:

[0056] See also Figure 3The air outlet of the air source device 10 is connected to the first air pipe 11, the air inlet of the precision instrument 30 is connected to the second air pipe 32, the first bellows 610 is connected to the first air pipe 11 through the first flange 210, and the second bellows 620 is connected to the second air pipe 32 through the second flange 220, and the support member 100 is fixed on the rigid surface 20 (here is the wall), thereby completing the fixed connection of the gyro suspension angle device and the communication with the first air pipe 11 and the second air pipe 32.

[0057] The power gas supplied by the gas source device 10 enters the first bellows 610 from the first gas pipe 11 through the first flange 210, and the good flexibility of the first gas pipe 11 is used to achieve a vibration reduction effect;

[0058] At the same time, the first flange 210 transmits some of the vibration of the power gas to the support member 100. Of the vibration transmitted to the support member 100, a portion of the vibration is transmitted to the wall through the support member 100, thereby reducing this portion of the vibration. Another portion of the vibration transmitted to the support member 100 is transmitted to the first gyro suspension 410 through the support member 100. The first gyro suspension 410 transmits this portion of the vibration to the rigid bend 300 through the first cable 510. Due to the good flexibility of the first cable 510, the first cable 510 reduces this portion of the vibration, and the remaining vibration is transmitted to the rigid bend 300.

[0059] The power gas enters the rigid elbow 300 through the first bellows 610. Since the first bellows 610 has good flexibility, it can reduce some vibrations, and the remaining vibrations are transmitted to the rigid elbow 300.

[0060] The power gas in the rigid curved pipe 300 is transmitted from the first pipe section 310 to the second pipe section 320. During this process, the rigid curved pipe 300 transmits part of its vibration to the second cable 520. The second cable 520 has good flexibility, which reduces some of the vibration. The remaining vibration is transmitted to the second gyro suspension 420 through the second cable 520, and then to the second flange 220 through the second gyro suspension 420.

[0061] The motive gas in the second pipe section 320 enters the second air pipe 32 through the second bellows 620. The second bellows 620 has a relatively good flexibility to reduce vibrations of the motive gas entering the second air pipe 32. When the motive gas enters the precision instrument 30 through the second air pipe 32, the relatively good flexibility of the second air pipe 32 reduces vibrations.

[0062] After the vibration is reduced by the first air pipe 11, the wall, the first cable 510, the first bellows 610, the second cable 520, the second bellows 620 and the second air pipe 32, the vibration is significantly reduced, and the vibration can be basically controlled at the micron level. In addition, the vibration reduction effect of the vibration reduction platform 31 on the precision instrument 30 makes the vibration finally transmitted to the precision instrument 30 negligible, providing a strong guarantee for the smooth operation of the precision instrument 30.

[0063] It should be noted that the above-mentioned air source equipment 10, rigid surface 20 and precision instrument 30 are in three different motion systems. That is to say, if there is no contact between the three of them through the connecting pipeline, each of them is almost an independent motion system. In the technical solution provided in this embodiment, the air source equipment 10 is on the ground 12, the rigid surface 20 is the fixed surface of the support 100, and the precision instrument 30 is installed on the vibration reduction platform 31.

[0064] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
