Description

Technical Field

[0001] This utility model relates to the field of gas pipeline connection technology, and in particular to a gas pipeline connection device for analytical instruments. Background Technology

[0002] Analytical instruments are devices used to measure and detect the physical, chemical, and biological properties of substances and acquire information. They are used in scientific research, industrial production, environmental monitoring, and medical and health fields. By performing qualitative or quantitative analysis on the composition, structure, and content of samples, they provide data support for scientific research. There are many types of analytical instruments, and the precise control of gas delivery and distribution makes gas pipeline connection devices an integral part of analytical instruments.

[0003] The function of a gas pipeline connection device for an analytical instrument is to achieve reliable connection between gas pipelines, ensure that gas can be stably transmitted between the components of the analytical instrument according to a predetermined path, accurately connect the gas source to the analytical instrument, maintain the gas pressure and flow rate within a suitable range, ensure the normal operation of the analytical instrument, and improve the accuracy and repeatability of analytical results. It is necessary to avoid gas leakage, reduce gas loss during transmission, and facilitate installation, disassembly and maintenance, thereby improving the ease of use and work efficiency of the analytical instrument.

[0004] Existing gas pipeline connection devices for analytical instruments have shortcomings in terms of gas flow stability. Current devices typically control gas flow through regulating valves, using the opening and closing degree of the valve core to change the gas flow cross-sectional area, thereby achieving initial regulation of the gas flow. Pressure sensors monitor pipeline pressure in real time and feed back to the control equipment for flow correction, avoiding large deviations in gas flow due to pressure fluctuations. However, due to the gap between the regulating valve core and the valve seat, and the wear of the valve core during frequent operation, micro-leakage occurs when gas passes through the regulating valve, affecting the accuracy of flow control. This makes it easy for turbulence to form when the gas flows in the pipeline, resulting in unstable gas flow and failing to meet the requirements of analytical instruments with extremely high gas flow stability. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gas pipeline connection device for analytical instruments, which aims to improve the problem of poor gas flow stability in the prior art.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when gas enters the high-pressure gas pipe from the gas pipe connector, the high-pressure spring in the one-way gas valve pushes the stop ball.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of an analytical instrument gas pipeline connection device, comprising multiple connector housings 1 for installing and protecting gas pipe connectors 3, achieving stable installation of pipeline connection components. Gas pipe connectors 3 are fixedly connected to the inner sides of each of the multiple connector housings 1, serving to connect high-pressure gas pipe 7 assemblies and ensuring stable connection of the gas flow channel. Two baffles 4 are fixedly connected to the inner sides of each of the multiple gas pipe connectors 3, defining the position of pressure dividing plates 5 and simultaneously guiding the gas flow path. The same pressure dividing plate 5 is fixedly connected between adjacent baffles 4, diverting or dividing the gas passing through the gas pipe connectors 3 to ensure uniform and stable gas delivery. Ventilation holes 6 are provided in the middle of the inner sides of each of the two baffles 4, providing a flow channel for the gas and ensuring smooth passage of the gas pipe connectors 3. High-pressure gas pipes 7 are connected to the rear sides of each of the multiple gas pipe connectors 3 for delivering high-pressure gas, ensuring efficient gas transmission in the pipeline. Each of the multiple high-pressure gas pipes 7 has a one-way valve 8 fixedly connected to the front of its inner wall to prevent gas backflow and ensure that the gas flows in a preset direction. Each of the multiple one-way valves 8 has a high-pressure spring 10 fixedly connected to its rear inner wall, which cooperates with the ball stop 9 to provide a reset force for the one-way valve 8 and maintain the one-way conduction function. Each of the multiple high-pressure springs 10 has a ball stop 9 fixedly connected to its front side, which cooperates with the one-way valve 8 under the action of gas pressure to realize one-way gas flow control. Each of the multiple high-pressure gas pipes 7 has a gas transfer device 11 connected to its rear side to centrally transfer and distribute the gas transported by the multiple high-pressure gas pipes 7, so that the gas enters the detector 12. Each of the multiple gas transfer devices 11 has a fixedly connected detector 12 to its rear side, which is used to detect and analyze the gas and obtain gas data. Each of the multiple gas transfer devices 11 has a gas pressure detection mechanism 2 on its top, which is used to detect whether the gas is leaking, detect gas leaks in the pipeline in time, and ensure safe use.

[0033] Specifically, the front of the high-pressure air pipe 7 is connected to the air pipe connector 3. The air pipe connector 3 is installed inside the connector housing 1. The connector housing 1 provides installation and protection for the air pipe connector 3, achieving a stable connection. The two baffles 4 inside the air pipe connector 3 define the position of the pressure dividing plate 5 and simultaneously guide the gas flow path. The vent 6 opened in the middle of the inner side of the two baffles 4 provides a flow channel for the gas. The pressure dividing plate 5 divides or reduces the pressure of the gas passing through the air pipe connector 3, so that the gas enters the high-pressure air pipe 7 evenly and stably. The high-pressure gas is first transported through the high-pressure air pipe 7. The one-way valve 8, with the high-pressure spring 10 connected to the rear inside, cooperates with the baffle ball 9. When the high-pressure gas flows into the high-pressure air pipe 7 from front to back, the gas pressure... The high-pressure spring 10 is compressed by pushing the baffle ball 9, allowing the gas to pass smoothly through the one-way valve 8. When the gas shows a backflow tendency, the high-pressure spring 10 pushes the baffle ball 9 to reset, closing the one-way valve 8 to prevent gas backflow and ensure that the gas flows in the preset direction. The gas delivered by multiple high-pressure gas pipes 7 converges to the gas transferor 11, which centrally transfers and distributes the gas. The gas is then delivered to the detector 12, which detects and analyzes the gas to obtain gas data. The gas pressure detection mechanism 2 set on the top of the gas transferor 11 monitors the gas pressure in real time. If an abnormal gas pressure is detected, it is determined that there is a gas leak, and the gas leak problem in the pipeline is detected in time to ensure the safe use of the device.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The air pressure testing mechanism 2 includes multiple connecting hoses 201, which are used to flexibly connect gas pipelines, effectively buffering pipeline vibration and preventing gas leakage or pipeline damage. The tops of each connecting hose 201 are connected to the same three-way closure 202, which allows for flexible control of gas flow. Different pipeline channels can be opened or closed according to testing requirements to ensure accurate gas transmission. A transmission pipe 203 is connected to the front of the three-way closure 202, which is used to stably transmit gas and ensure that the gas... The gas is safely and efficiently transported to the subsequent testing components. A controller 204 is fixedly connected to the rear side of the transmission tube 203. The controller 204 intelligently regulates the gas transmission process, accurately controls the gas flow and pressure parameters, and ensures the reliability of the test data. A data line 205 is connected to the left side of the controller 204. The data line 205 is used to transmit control signals and test data. The bottom end of the data line 205 is connected to a display 206 and is fixedly connected to the external left side of the detector 12. The display 206 displays the gas test data in real time, making it easy for operators to understand the test status.

[0035] Specifically, during the air pressure testing process, gas enters the air pressure testing mechanism 2 through multiple connecting hoses 201. The connecting hoses 201 provide flexible connections for the gas pipeline, effectively buffering vibrations generated during pipeline operation and preventing gas leakage or pipeline damage due to vibration, thus providing stability for gas transmission. The tops of the multiple connecting hoses 201 are all connected to a three-way closure 202. According to specific testing needs, the operator opens or closes different pipeline channels by operating the three-way closure 202, achieving flexible control of the gas flow direction, thereby ensuring accurate gas transmission along a predetermined path. The gas, after being regulated by the three-way closure 202, will enter the transmission... The transmission pipe 203 stably delivers gas to the subsequent detection components, ensuring safe and efficient gas transmission. When the gas reaches the controller 204, the controller 204 begins to regulate and ensure that the gas enters the detection stage in a suitable state, guaranteeing the reliability of the detection data. The controller 204 transmits the processed control signal and the data generated during the detection process to the display 206 via the data cable 205. The display 206 is connected to the external left side of the detector 12, enabling real-time display of gas detection data. This allows operators to understand the detection situation in a timely and intuitive manner, achieving efficient and accurate operation of the gas pressure detection work.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The bottom of the detector 12 is fixedly connected to four corners with base columns 13, which support the detector 12 and ensure the stability of the detector 12. The bottom of the multiple base columns 13 is fixedly connected to the bottom with fixing blocks 23, which can increase the contact area with the placement surface and enhance the stability of the placement. The bottom center of the detector 12 is threadedly connected to a fixing plate 14, which is convenient for installation and removal. The bottom of the fixing plate 14 is fixedly connected to a stabilizing spring 15, which plays a buffering and shock-absorbing role when the detector 12 is subjected to vibration, reducing the impact of vibration on the internal components of the detector 12. The front top of the connector housing 1 is fixedly connected to a pressure gate 18, which can control and regulate the air pressure in the gas pipeline. The bottom of the pressure gate 18 is rotatably connected to a blocking ball 19 and is set on the inner wall of the connector housing 1. According to the control of the pressure gate 18, the flow of gas is blocked or opened by the blocking ball 19.

[0037] Specifically, when placing the detector 12, the base column 13 provides support for the detector 12, ensuring the stability of its placement. The fixing block 23 connected to the bottom of the base column 13 increases the contact area with the placement surface, enhancing the stability of the placement. When the detector 12 is subjected to vibration, the stabilizing spring 15 connected to the bottom of the fixing plate 14 absorbs the vibration energy through deformation, achieving a buffering and shock-absorbing effect, reducing the impact of vibration on the internal components of the detector 12. In terms of gas pipeline control, the pressure gate 18 controls and adjusts the gas pressure in the gas pipeline according to actual needs. The blocking ball 19 will block or open the gas flow according to the closing of the pressure gate 18. When it is necessary to block the gas flow, the pressure gate 18 controls the blocking ball 19 to rotate and block the gas from passing through; when it is necessary to open the gas flow...

[0038] Reference Figure 2 and Figure 3 A positioning ring 20 is fixedly connected to the front side of the outer wall of the connector housing 1. The positioning ring 20 plays a positioning role in the connection position, which facilitates accurate installation. Two slots 21 are opened on the front side of the outer wall of the air pipe connector 3. The slots 21 are used to cooperate with the components to achieve a stable connection. Multiple air pressure columns 22 are fixedly connected to the left side of the display 206. The air pressure columns 22 adopt an equidistant design and display the air pressure information of the gas transfer unit 11. Through mechanical liquid lifting, the pressure situation can be quickly reflected. Multiple pressure gauges 16 are fixedly connected to the bottom of the three-way closure 202. The pressure gauges 16 can monitor and identify the internal air pressure value in real time. An alarm 17 is connected to the rear left side of the three-way closure 202. The alarm 17 can issue an alarm in time when the air pressure is abnormal.

[0039] Specifically, the positioning ring 20 serves to position the connection. When the gas pipe connector 3 and the gas pipeline are installed, the positioning ring 20 ensures that the gas pipe connector 3 is in the correct position, facilitating accurate installation. When the two slots 21 are connected to the connector components of the gas pipeline, they cooperate with the corresponding locking structure to achieve a stable connection, ensuring the stability of the gas transmission channel. After the gas enters the equipment, the pressure column 22 adopts a mechanical liquid lifting principle, which can quickly react to the pressure situation and facilitate real-time observation by the operator. Multiple pressure gauges 16 monitor the internal pressure values ​​of the equipment in real time, providing accurate data support for equipment pressure monitoring. When the pressure is abnormal, the alarm 17 will promptly issue an alarm to remind the staff to take appropriate measures to avoid safety accidents or equipment failures caused by abnormal pressure.

[0040] Working principle: The gas is connected to the gas pipe connector 3 of the gas connector and connector housing 1, allowing the gas to be precipitated. Inside the gas pipe connector 3, two baffles 4 limit the position of the pressure dividing plate 5 and simultaneously guide the gas flow path. The pressure dividing plate 5 divides or pressurizes the gas passing through the gas pipe connector 3, allowing the gas to enter the high-pressure gas pipe 7 evenly and stably. The high-pressure gas is first transported through the high-pressure gas pipe 7. The one-way valve 8 has a high-pressure spring 10 connected to the rear side inside, which cooperates with the baffle ball 9. When the high-pressure gas flows into the high-pressure gas pipe 7 from front to back, the gas pressure pushes the baffle ball 9 to compress the high-pressure spring 10, allowing the gas to pass smoothly through the one-way valve 8. When the gas shows a backflow tendency, the high-pressure spring 10 pushes the baffle ball 9 to reset, closing the one-way valve 8 to prevent gas backflow and ensure that the gas flows in the preset direction. The gas transported by multiple high-pressure gas pipes 7 converges to the gas transferor 11. The gas transferor 11 centrally transfers and distributes the gas, and then the gas is transported to the detector 12, which detects and analyzes the gas to obtain gas data.

[0041] During the air pressure testing process, gas enters the air pressure testing mechanism 2 through multiple connecting hoses 201. According to specific testing requirements, the operator opens or closes different pipeline channels by operating the three-way closure device 202. After being regulated by the three-way closure device 202, the gas enters the transmission pipe 203. The transmission pipe 203 stably delivers the gas to the controller 204, ensuring safe and efficient gas transmission. When the gas is transmitted to the controller 204, the controller 204 begins to regulate and ensure that the gas enters the testing stage in a suitable state, ensuring the reliability of the testing data. The processed control signal and the data generated during the testing process are transmitted to the display 206 through the data cable 205, which can display the gas testing data in real time, realizing efficient and accurate operation of the air pressure testing work.
