Technical Field

[0001] The present application relates to the technical field of pressure measurement, and particularly relates to a slider and a scanning valve for a 64-channel pressure scanning valve. Background Art

[0002] With the continuous improvement of the requirements for pressure measurement accuracy and efficiency in modern industry, as an important test device, the pressure scanning valve is widely used in fields such as aerospace, automotive, and wind tunnel testing. Traditional pressure scanning valves usually adopt a 32-channel design, but their design and functions have not fully met the growing industrial needs. Especially in multi-channel and high-efficiency pressure measurement scenarios, there are some limitations in existing technical solutions.

[0003] One of the main challenges faced by the design of existing 32-channel pressure scanning valves is the complexity of gas path management. In a multi-channel pressure measurement system, the smoothness and stability of the gas path are crucial for ensuring the accuracy of measurement results. However, the existing design may experience problems with unsmooth gas paths during long-term operation or under complex working conditions, which may affect the stability and reliability of measurement data. In addition, as the number of channels increases, the challenges for gas path design also increase, and a new pressure scanning valve design that can adapt to more channels and maintain gas path stability is needed. Summary of the Invention

[0018] In some embodiments, it further includes a calibration system having a calibration input port and a calibration output port. The calibration input port is located on the top surface of the top of the slider, and the calibration output port is located on the front side and the rear side of the slider;

[0019] The measurement output port and the calibration output port are both arranged in the following way: two sides, two zones on each side, two rows in each zone, eight in each row, and the measurement output port and the calibration output port in each row are arranged crosswise, and the distance between the measurement output port and the calibration output port is equal to the distance between the measurement station and the calibration station.

[0020] In some embodiments, the purging system is further provided with purging air ports which communicate with the purging channels and are located on the front side and the rear side of the slider.

[0021] This application also provides a scanning valve, including the slider for the 64-channel pressure scanning valve described above.

[0022] Compared with the above background art, the slider for the 64-channel pressure scanning valve and the scanning valve provided by this application mainly include a measurement system and a purging system.

[0023] One of the main challenges faced by the existing 32-channel pressure scanning valve mentioned in the background art is the complexity of gas path management.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0036] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0037] Please refer to Figure 1 , Figure 1 It is a schematic diagram of the slider for the 64-channel pressure scanning valve provided by the embodiment of the present application.

[0038] In the first specific embodiment, the slider and the scanning valve for a 64-channel pressure scanning valve provided by the implementation scheme of the present application mainly include a measurement system 1 and a purging system 5. The measurement system 1 is provided with a communicating measurement input port 11 and a measurement output port 12. When the slider is in the measurement position, the measurement input port 11 is connected to the gas guiding component, and the measurement output port 12 is used to provide a measurement pressure to the first side of the pressure chip. The purging system 5 is provided with a communicating purging input port 51 and a purging output port 52. The purging input port 51 is used to input purging gas. When the slider is in the purging position, the purging output port 52 is connected to the gas guiding component, and the inside of the gas guiding component is purged by the purging gas.

[0039] One of the main challenges faced by the existing 32-channel pressure scanning valve mentioned in the background art is the complexity of gas path management. Especially during long-term operation or under complex working conditions, problems such as poor gas path flow may occur, which directly affects the stability and reliability of measurement data. In addition, with the increase in the number of channels, the challenges for gas path design are also increasing, and a new type of pressure scanning valve design that can adapt to more channels and maintain gas path stability is needed.

[0040] To address this technical problem, the slider and the scanning valve for a 64-channel pressure scanning valve provided by the present application effectively solve the above challenges through the innovative integration of the measurement system 1 and the purging system 5. Specifically, the design of the measurement system 1 enables the connection of the gas guiding component through the measurement input port 11 and the measurement output port 12 when the slider is in the measurement position, and provides a measurement pressure to the first side of the pressure chip, ensuring the accuracy of the measurement process. The introduction of the purging system 5, when the slider is in the purging position, uses the purging input port 51 to input purging gas, and makes the purging output port 52 connected to the gas guiding component, and purges the inside of the gas guiding component through the purging gas, thereby removing impurities or blockages that may accumulate in the gas path and maintaining the smoothness of the gas path.

[0041] This design not only improves the measurement accuracy of a single channel, but also enhances the stability and reliability of the entire multi-channel system through the application of the purging system 5. By performing purging operations regularly or as needed, problems such as poor gas path flow can be prevented, maintenance requirements can be reduced, and the equipment life can be extended.

[0042] Combined with the above structural and process descriptions, it can be seen that the slider for a 64-channel pressure scanning valve has at least the following beneficial effects: The slider for a 64-channel pressure scanning valve effectively solves the problem of poor gas path flow in a multi-channel pressure scanning valve by integrating the purging system 5, improving the measurement accuracy and the stability of the system.

[0043] It should be noted that the pressure in this embodiment usually refers to gas pressure. The gas guiding component in this embodiment usually includes a gas guiding plate and a gas connector.

[0044] When using the slider for the 64-channel pressure scanning valve provided by the present application, the slider slides in the scanning valve, and there are non-coincident measurement stations and purging stations in its moving direction. When the slider moves to the measurement station, the measurement input port 11 in the measurement system 1 is connected to the air guiding component, and the measurement pressure is introduced through the air guiding component, so that the measurement output port 12 can provide the measurement pressure to the first side of the pressure chip for pressure measurement. At this time, the slider is located at the measurement station and is in the measurement state.

[0045] When the slider further moves to the purging station, the purging input port 51 in the purging system 5 is used to input purging gas, and the connected object of the air guiding component is switched from the measurement input port 11 in the measurement system 1 to the purging output port 52 of the purging system 5. The inside of the air guiding component is purged by the purging gas to remove impurities or blockages that may accumulate in the gas path and maintain the smoothness of the gas path. At this time, the slider is located at the purging station and is in the purging state.

[0046] In this way, the switching of the slider between different stations realizes two states of measurement and purging.

[0047] In some embodiments, the slider further includes: a calibration system 2, which has a communicating calibration input port 21 and calibration output port 22. The calibration input port 21 is used to introduce calibration pressure, and when the slider is at the calibration station, the calibration output port 22 is used to provide calibration pressure to the first side of the pressure chip.

[0048] In this embodiment, the design of the slider not only includes the measurement system 1 and the purging system 5, but also extends to the calibration system 2 to enhance the functionality and flexibility of the pressure scanning valve. The calibration system 2 consists of a calibration input port 21 and a calibration output port 22, and these two components are in communication. The main function of the calibration input port 21 is to introduce calibration pressure. When the slider moves to a specific calibration station, the calibration pressure enters the system through the calibration input port 21, and the calibration output port 22 transfers the calibration pressure to the first side of the pressure chip. This process is crucial for ensuring the accuracy of pressure measurement and the accuracy of the calibration process.

[0049] By operating at the calibration station, the slider can provide the necessary calibration pressure to adjust or calibrate the performance of the pressure chip to ensure reliable measurement results under various working conditions. This design enables the slider not only to perform conventional pressure measurement and purging operations, but also to execute calibration tasks, thereby improving the operation efficiency and measurement accuracy of the entire system.

[0050] When using the slider for the 64-channel pressure scanning valve provided by the present application, the slider slides in the scanning valve, and there are non-coincident measurement stations and calibration stations in its moving direction.

[0051] When the slider moves to the calibration station, the calibration air pressure is introduced into the calibration input port 21 in the calibration system 2, and the calibration output port 22 is responsible for transmitting the calibration pressure to the first side of the pressure chip for pressure calibration. At this time, the slider is located at the calibration station and is in the calibration state.

[0052] It should be noted that the test station and the calibration station are designed not to coincide, which means that the slider can only be at one station at the same time. Therefore, the different states that the slider can switch between include the measurement state and the calibration state, but the slider cannot be in both states simultaneously. In other words, the slider can only perform measurements at the test station to provide real-time pressure data, and perform calibration when moving to the calibration station to ensure the overall accuracy of the measurement system. The design and operating mechanism of the slider enable it to perform only one of the functions of testing and calibration at the same time, that is, perform measurements at the test station or perform calibration at the calibration station, rather than performing both measurements and calibration simultaneously. Such a design ensures the accuracy of operation and the stability of the system, while also improving work efficiency and avoiding confusion or errors that may be caused by performing multiple operations simultaneously.

[0053] In some embodiments, the purge station and the calibration station coincide.

[0054] In this embodiment, the purge station and the calibration station are designed to coincide, and this design allows the slider to achieve the dual functions of purging and calibration at the same station. Specifically, when the slider is located at this coincident station, it can be in either the purge state or the calibration state, depending on the configuration and operating mode of the slider. The advantage of this design is that, compared with the case where the purge station and the calibration station are independently separated, the coincident design makes the structure of the slider more compact and smaller in volume.

[0055] Such a compact design reduces the distance the slider moves within the scan valve and the required space, thus saving the overall volume of the equipment, which is particularly beneficial for application scenarios with limited space. At the same time, due to the coincidence of the stations, the slider switches between different stations more efficiently, reducing mechanical wear and operating time, and improving the operating efficiency and reliability of the equipment. In addition, the compactification of the structure also helps to reduce manufacturing costs and maintenance difficulties, making the entire system more economical and practical. In summary, the coincident design of the purge station and the calibration station provides an effective solution for realizing multi-functional integration and equipment miniaturization.

[0056] In a specific implementation manner, for the measurement station, calibration station, and purge station designed for the measurement system 1, calibration system 2, and purge system 5, the calibration station and the purge station coincide and can be regarded as the first position, which means that at this position, the slider can perform both calibration operations and purge operations. The measurement station, which does not coincide with the calibration station, can be regarded as the second position and is specifically used for the measurement operation of the slider.

[0057] Therefore, when the slider is in the first position, corresponding to the calibration / purging state of the slider, the slider can perform precise pressure calibration using the calibration system 2, or use the purging system 5 to remove impurities in the gas path, maintaining the cleanliness and performance of the system. Conversely, when the slider moves to the second position, i.e., the measurement station, the slider is in the measurement state and uses the measurement system 1 to perform the pressure measurement task. Such a design enables the slider to switch between different stations to adapt to different operation requirements, ensuring the accuracy of measurement and the efficient operation of the system.

[0058] In some embodiments, the slider further includes:

[0059] A measurement reference system 3, having a communicating measurement reference input port 31 and measurement reference output port 32. The measurement reference input port 31 is used to introduce a measurement reference pressure. When the slider is at the measurement station, the measurement reference output port 32 is used to provide a measurement reference pressure to the second side of the pressure chip;

[0060] A calibration reference system 4, having a communicating calibration reference input port 41 and calibration reference output port 42. The calibration reference input port 41 is used to introduce a calibration reference pressure. When the slider is at the calibration station, the calibration reference output port 42 is used to provide a calibration reference pressure to the second side of the pressure chip.

[0061] In this embodiment, the slider includes a measurement reference system 3 and a calibration reference system 4, and these two systems are crucial for the precise operation of the differential pressure type pressure chip. The working principle of the differential pressure type pressure chip is based on receiving different pressure signals on both sides of the chip to measure the pressure difference.

[0062] When the slider is in the measurement state, the first side of the pressure chip receives the measurement pressure through the measurement output port 12 of the measurement system 1, while the second side receives the measurement reference pressure through the measurement reference output port 32 of the measurement reference system 3. This configuration allows the pressure chip to measure the difference between the actual pressure value and the reference pressure value, thereby obtaining accurate measurement results.

[0063] In the calibration state, the slider is located at the calibration station. At this time, the first side of the pressure chip receives the calibration pressure through the calibration output port 22 of the calibration system 2, while the second side receives the calibration reference pressure through the calibration reference output port 42 of the calibration reference system 4. Such a design enables the calibration process to precisely adjust the pressure chip, ensuring that it can provide accurate measurements under various operating conditions.

[0064] With this design, the slider can provide the necessary pressure signal for the pressure chip during the measurement and calibration processes, ensuring the accuracy of measurement and calibration. The application of this differential pressure principle enables the slider to effectively operate on the pressure chip under different working conditions, improving the performance and reliability of the entire system.

[0065] In some embodiments, the measurement system 1 includes 64 mutually independent measurement channels located inside the slider. The two ends of the measurement channels are provided with a measurement input port 11 and a measurement output port 12.

[0066] The purging system 5 includes 64 purging channels that are connected at the first ends and independent at the tail ends. The purging channels are located inside the slider. The first end of the purging channel is provided with a purging input port 51, and the tail end of the purging channel is provided with a purging output port 52.

[0067] In this embodiment, the design of the measurement system 1 includes 64 mutually independent measurement channels. The two ends of these measurement channels are respectively provided with a measurement input port 11 and a measurement output port 12. Each measurement channel can independently perform pressure measurement, ensuring that there is no mutual interference between channels during multi-channel operation, thereby improving the accuracy and reliability of measurement.

[0068] At the same time, the purging system 5 includes 64 purging channels that are connected at the first ends, meaning they share a common purging input port 51 for introducing purging gas. This design allows the purging gas to enter the first ends of all purging channels simultaneously, thereby performing a unified cleaning process on the entire gas guiding assembly. The tail ends of the purging channels are independent, and each tail end of the purging channel is provided with an independent purging output port 52. Such a design allows the purging gas of each purging channel to be independently discharged from the gas guiding assembly, ensuring that each channel can be thoroughly cleaned.

[0069] This design enables the purging system 5 to effectively remove possible impurities or blockages inside the gas guiding assembly that originally served 64 independent measurement channels. Through the configuration of common gas inlet at the first end and independent gas outlet at the tail end, the purging system 5 achieves comprehensive purging of the gas guiding assembly, improving the cleaning efficiency and ensuring the smooth gas path and measurement accuracy of each measurement channel during the measurement process.

[0070] In some embodiments, the measurement input port 11, the purging input port 51, and the purging output port 52 are located on the top surface of the top of the slider, and the measurement output port 12 is located on the front side and the rear side of the slider.

[0071] In this embodiment, the design of the slider takes into account the layout of the pressure chip and the gas guiding component to optimize the connection and facilitate management. Specifically, the measurement input port 11, the purge input port 51, and the purge output port 52 are arranged on the top surface of the top of the slider. This layout allows the gas guiding component to be compactly installed on the top of the slider, while simplifying the connection of the external gas source and the layout of the purge system 5.

[0072] At the same time, the measurement output port 12 is arranged on the front side and the rear side of the slider, corresponding to the position of the pressure chip. Since the pressure chip is usually installed on the front side and the rear side of the slider, such a design enables the measurement output port 12 to be directly connected to the pressure chip, providing a channel for measuring pressure. This layout not only simplifies the internal structure of the slider but also makes the connection between various components more direct and efficient, facilitating management and maintenance.

[0073] Through this layout, the design of the slider achieves optimized connection, reduces the complexity of the connection, and improves the operating efficiency of the entire system. Such a layout design takes into account the convenience of actual operation, helps to improve the stability and reliability of the system, and also reduces the maintenance difficulty and cost.

[0074] In some embodiments, the measurement input port 11 and the purge output port 52 are arranged in the following way: two zones, four rows in each zone, eight in each row, and the measurement input port 11 and the purge output port 52 in each row are arranged crosswise, and the distance between the measurement input port 11 and the purge output port 52 is equal to the distance between the measurement station and the purge station.

[0075] In this embodiment, the layout design of the top surface of the slider adopts an orderly and symmetrical arrangement, especially for the measurement input port 11 and the purge output port 52. These interfaces are divided into two zones, each zone contains four rows, and each row has eight interfaces, achieving a layout of two zones, four rows in each zone, and eight in each row. Specifically, the measurement input port 11 and the purge output port 52 are arranged crosswise in each row. This crosswise layout helps to optimize the space utilization and may improve the flexibility and efficiency of the connection.

[0076] In addition, the distance between the measurement input port 11 and the purge output port 52 is designed to be equal to the distance between the measurement station and the purge station. This design means that when the slider moves a certain distance to switch from one station to another, the relative position between each interface remains consistent, thus ensuring a smooth transition and precise docking of the slider between different stations. This precise layout is crucial for ensuring the accuracy of the measurement and purge operations, and also simplifies the design and manufacturing process of the slider because it reduces the complex connections between the interfaces and potential errors. Through this carefully designed layout, the slider can efficiently perform its functions while maintaining the compactness of the structure and the simplicity of the operation.

[0077] In some embodiments, the slider further includes a calibration system 2 provided with a calibration input port 21 and a calibration output port 22. The calibration input port 21 is located on the top surface of the top of the slider, and the calibration output port 22 is located on the front side and the rear side of the slider; both the measurement output port 12 and the calibration output port 22 are arranged in the following manner: two sides, two areas per side, two rows per area, eight in each row, and the measurement output port 12 and the calibration output port 22 in each row are arranged crosswise, and the spacing between the measurement output port 12 and the calibration output port 22 is equal to the spacing between the measurement station and the calibration station.

[0078] In this embodiment, the calibration input port 21 is arranged on the top surface of the top of the slider. This layout is beneficial for introducing the calibration pressure and managing the position where the calibration pressure is introduced, while the calibration output port 22 is arranged on the front side and the rear side of the slider, corresponding to the position of the pressure chip, facilitating the supply of the calibration pressure to the pressure chip.

[0079] The measurement output port 12 and the calibration output port 22 are arranged in a specific pattern to optimize space utilization and operation efficiency. This arrangement is designed to be two sides, two areas per side, two rows per area, eight in each row, that is, there are two areas on the front side and the rear side of the slider respectively, each area has two rows, and each row contains eight output ports. In particular, the measurement output port 12 and the calibration output port 22 are arranged crosswise in each row. This crosswise layout helps to reduce space occupancy and at the same time ensures the efficiency of the measurement and calibration processes.

[0080] In addition, the spacing between the measurement output port 12 and the calibration output port 22 is precisely designed to be equal to the spacing between the measurement station and the calibration station. This design allows the slider to accurately dock with the corresponding output ports when moving to the corresponding stations, ensuring the precise docking of the measurement and calibration processes and the reliability of the operation. Through this carefully designed layout, the slider can smoothly transition between different stations while maintaining the simplicity of the operation and the stability of the system.

[0081] In a specific implementation, due to the coincidence of the calibration station and the purging station, the slider has a specific corresponding relationship at different stations. Specifically, the spacing between the measurement input port 11 and the purging output port 52 is designed to be equal to the spacing between the measurement station and the purging station, which is equivalent to the moving distance of the slider between the first position (i.e., the calibration / purging station) and the second position (i.e., the measurement station).

[0082] Similarly, the spacing between the measurement output port 12 and the calibration output port 22 is also designed to be equal to the spacing between the measurement station and the calibration station, which also corresponds to the moving distance of the slider between the first position and the second position. Therefore, the spacing between the measurement input port 11 and the purging output port 52 is equal to the spacing between the measurement output port 12 and the calibration output port 22, which means that during the conversion of the slider between the two stations, the corresponding relationship and the spacing between the interfaces remain consistent.

[0083] This equidistant design simplifies the conversion mechanism of the slider between different workstations, improving the flexibility and accuracy of operation. It also helps to reduce the alignment errors that may be caused by inconsistent workstation spacings, ensuring the continuity and reliability during measurement and calibration at different workstations. By maintaining a consistent spacing between these key interfaces, the design of the slider becomes more efficient, while also reducing the complexity of manufacturing and maintenance.

[0084] In some embodiments, the purging system 5 is further provided with purging air ports 53, which communicate with the purging channels and are located on the front and rear sides of the slider.

[0085] In this embodiment, the design of the purging system 5 further includes purging air ports 53 that are connected to the purging channels. Such a layout allows the purging gas to directly act on the relevant areas of the gas guiding assembly through the purging air ports 53, further expanding the scope of cleaning and maintenance. The design of the purging air ports 53 aims to optimize the flow path of the purging gas, ensuring the effectiveness of the purging operation while maintaining the compactness of the structure and the simplicity of operation. Through this design, the purging system 5 can more efficiently remove impurities in the gas path, maintaining the normal operation of the system and the accuracy of measurement.

[0086] In some embodiments, the measurement reference system 3 is provided with a measurement reference input port 31 and two measurement reference output ports 32, and the calibration reference system 4 is similarly provided with a calibration reference input port 41 and two calibration reference output ports 42. The measurement reference input port 31 and the calibration reference input port 41 are located on the top surface of the slider, and the measurement reference output ports 32 and the calibration reference output ports 42 are located on the front and rear sides of the slider. The arrangement of the measurement reference output ports 32 and the calibration reference output ports 42 is such that there are two on each of the two sides, and the spacing between the measurement reference output ports 32 and the calibration reference output ports 42 is equal to the spacing between the measurement workstation and the calibration workstation, i.e., the spacing between the first position and the second position.

[0087] In some cases, the spacing between the first position and the second position is 1.7 mm.

[0088] This application also provides a scanning valve, including the slider for the above-mentioned 64-channel pressure scanning valve.

[0089] This scanning valve should have all the beneficial technical effects of the above-mentioned slider for the 64-channel pressure scanning valve; in addition to the slider, the scanning valve further includes a gas guiding assembly, a pressure chip, and a corresponding control system.

[0090] The air guiding component is responsible for connecting the pressure source to the measurement input port 11 on the slider, ensuring that the pressure signal can be accurately transmitted to the pressure chip. Additionally, the air guiding component is also responsible for transmitting the reference pressure to the pressure chip. The pressure chip, as the core component for measuring pressure, is arranged on the front and rear sides of the slider, corresponding to the measurement output port 12 and the calibration output port 22, to sense pressure changes. Additionally, the pressure chip also senses the reference pressure. The control system is mainly used to control the movement of the slider in the valve body, ensuring that the slider can accurately switch between the test station and the calibration / purging station, as well as control the supply of the pressure source and the flow of the purging gas.

[0091] Through the coordinated work of these components, the scanning valve can achieve high-precision pressure measurement and convenient maintenance operations, while maintaining a compact structure and simple operation, meeting the requirements of modern industry for pressure measurement equipment.

[0092] In a specific implementation manner, the usage process of the scanning valve is described as follows in combination with the slider for a 64-channel pressure scanning valve.

[0093] The movement of the slider in the scanning valve precisely controls the switching between the measurement, calibration, and purging functions. When pressure measurement needs to be performed, the slider moves to the measurement station, making the measurement input port 11 of the measurement system 1 connected to the air guiding component, and the measurement output port 12 is responsible for transmitting the measured pressure to the first side of the pressure chip, realizing the interconnection from 64 external air pipes to 64 pressure chips. During this process, the measurement reference system 3 ensures that each pressure chip can obtain the required measurement reference pressure during measurement.

[0094] Furthermore, when the system demand switches from the measurement mode to the calibration or purging state, the slider moves to the calibration / purging station. At this time, the control system controls the front piston to push the slider backward by 1.7 mm, so that the purging gas introduced through the purging input port 51 of the purging system 5 clears the impurities in the air guiding component through the purging output port 52. At the same time, the calibration output port 22 is responsible for transmitting the calibration pressure to the first side of the pressure chip. During this process, the calibration reference system 4 ensures that each pressure chip can obtain the required calibration reference pressure during measurement.

[0095] The significant advantage of this scanning valve is that the slider integrates the purging function, significantly improving the reliability of the scanning valve, and being able to implement two modes of purging and calibration at one station, effectively reducing the volume of the slider and the scanning valve. This design not only optimizes the space utilization but also reduces the system complexity and maintenance cost, making the scanning valve more efficient and reliable in multi-channel pressure measurement applications. Through this integrated design, the slider can provide efficient and accurate pressure measurement and system maintenance functions while maintaining a compact structure.
