Description

Technical Field

[0001] This utility model belongs to the field of pressure core testing technology, specifically relating to a matrix-type gas-liquid universal pressure core testing device. Background Technology

[0002] During the development of pressure cores, it is necessary to accurately test various performance indicators of the core, such as sensitivity, linearity, repeatability, and hysteresis. Conventional pressure core testing involves testing each core individually, which is inefficient and unsuitable for testing multiple types or multiple pressure cores.

[0003] Because it is necessary to test the pressure range and accuracy of the pressure core, existing testing devices cannot flexibly adjust the testing parameters to adapt to diverse R&D needs. For example, in the initial debugging stage of the pressure core, a wider pressure range and accuracy are needed to quickly screen out unqualified cores; in the later fine adjustment stage, a narrower pressure range and higher accuracy are needed to determine the precise performance of the core and achieve calibration and compensation.

[0004] Furthermore, existing testing devices struggle to control the consistency of the testing environment for each core when performing multi-core testing. Even minor differences in environmental factors (such as temperature and vibration) can affect the test results of the pressure core, leading to complex calibration processes and error accumulation, which in turn affects the accurate assessment of the core. Utility Model Content

[0005] To address the differences in existing technologies, this invention proposes a matrix-type universal gas-liquid pressure core testing device, comprising: a pressure core testing base, a testing interface sealing ring, a testing interface plug, a gas / liquid connector, and a pressure core testing assembly; the pressure core testing base includes multiple bases, multiple connecting pipes, and multiple testing interfaces; the testing interface sealing ring is disposed at the testing interface, and the pressure core testing assembly, gas / liquid connector, and testing interface plug are sequentially installed in the corresponding testing interface to achieve device sealing.

[0006] The beneficial effects of this utility model are: This invention utilizes a pressure core as the pressure-sensitive unit of a pressure sensor, which senses external pressure and converts the pressure signal into an electrical signal. Through multi-channel parallel detection and optimized elastic structure, this invention effectively expands the testing range and improves testing efficiency. Based on the gas / liquid transmission principle, the pressure at each pressure interface remains consistent in real time. Furthermore, the use of sealing rings with threaded pre-tightening provides a stable and reliable sealing connection, improving the accuracy of pressure testing. Attached Figure Description

[0008] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0009] A matrix-type universal gas-liquid pressure core testing device, such as Figure 1 As shown, the device includes: a pressure core test base 1, a test interface sealing ring 2, a test interface plug 3, a gas / liquid connector 4, and a pressure core test assembly 5; the pressure core test base includes multiple bases, multiple connecting pipes, and multiple test interfaces; the test interface sealing ring is set at the test interface, and the pressure core test assembly, gas / liquid connector, and test interface plug are sequentially installed in the corresponding test interfaces to achieve device sealing.

[0010] The pressure core test base consists of 1-1 the base, 1-2 the connecting pipe, and 1-3 the test interface. The base has a hollow internal structure to ensure the passage of gas / liquid media. All ends of the base are welded and sealed, and multiple matrix-style through holes are pre-drilled on the front for connection to the test interface. Single-sided through holes can be added to the sides of the base as needed, and these can be connected in series via connecting pipes to form a base assembly. Base assemblies can increase the number of tests per cycle and improve work efficiency.

[0011] The connecting pipe 1-2 has a through hole feature, which can be matched with the single-sided through hole on the side of the base and sealed by welding.

[0012] Test interfaces 1-3 have internal threads for installing the pressure core test assembly, test interface plug, and gas / liquid connector. The test interfaces also feature through-holes, which are sealed to the pre-drilled through-hole on the front of the base by welding, thus connecting the two through-holes.

[0013] The test interface sealing ring 2 is installed in the test interface. The pressure core test assembly, the test interface plug and the gas / liquid connector are connected to the test connector through threaded engagement. Under the action of thread preload, the test interface sealing ring is deformed by force, thereby achieving a seal.

[0014] The test interface plug 3 has an external thread feature, which, when used with the test interface sealing ring, can achieve a threaded connection and seal with the test interface. In particular, after sealing, the test interface plug will completely block the through hole of the test interface, preventing leakage of gas / liquid media.

[0015] The gas / liquid connector 4 has an external thread feature, which, when used with the test interface sealing ring, can achieve a threaded connection and seal with the test interface. Simultaneously, the gas / liquid connector has a through-hole feature, allowing communication with the through-hole of the test interface. The gas / liquid connector can be replaced and customized according to the characteristics of the measured medium and the different pipelines used to transmit the measured medium.

[0016] In this embodiment, as Figure 3 and 4 As shown, the pressure core test assembly consists of a 5-1 adapter, a 5-2 adapter sealing ring, a 5-3 pressure core, and a 5-4 adapter plug. The adapter has a through hole and a groove. The adapter sealing ring is located in the groove of the adapter. The pressure core is located in the groove and contacts the adapter sealing ring. The adapter plug is fixed in the groove, thus sealing the end face of the pressure core.

[0017] One end of the 5-1 adapter has external threads and a through hole, allowing it to be used with the test interface sealing ring to achieve a threaded connection seal with the test interface, while also communicating with the through hole of the test interface. The 5-1 adapter has a hexagonal structure, which can serve as a clamping force point during thread pre-tightening. The inner cavity of the 5-1 adapter has a stepped feature, allowing the installation of the 5-2 adapter sealing ring and the 5-3 pressure core. The inner cavity of the 5-1 adapter also has internal threads, allowing it to be used with the 5-2 adapter sealing ring and the 54 adapter plug to achieve a pre-tightening seal on the 5-3 pressure core.

[0018] The sealing ring of the 5-2 adapter fits tightly against the contact end face of the 5-3 pressure core. The sealing ring of the 5-2 adapter can be customized according to the size of the contact end face of the 5-3 pressure core.

[0019] The 5-3 pressure core is the pressure-sensitive unit of the pressure sensor, which has pin features for outputting signals.

[0020] The 5-4 adapter plug features a through-hole design, facilitating electrical connection of the 5-3 pressure core pins to the outside. Simultaneously, one end of the 5-4 adapter plug has an external thread, allowing for threaded connection with the internal thread of the 5-1 adapter. The thread preload ensures a tight seal between the 5-2 adapter sealing ring and the 5-3 pressure core contact surface, achieving a seal. The other end of the 5-4 adapter plug has a flat surface, facilitating thread preload.

[0021] In this embodiment, when using the device of the present invention to measure the pressure of the pressure core with a liquid medium, firstly, the 5-2 adapter sealing ring, the 5-3 pressure core, and the 5-4 adapter plug are sequentially installed into the inner cavity of the 5-1 adapter, completing the installation of the 5 pressure core test assembly. Then, the 1 pressure core test base assembly is placed on the worktable. Next, Figure 2 Any test interface serves as an air inlet, used to connect to an external liquid phase pipeline (measuring medium). Place the sealing ring into the sealing ring mounting position of test interfaces 1-3, then install the 5-pressure core test assembly into the test interface. Complete the installation of all 5-pressure core test assemblies to be tested sequentially. Use a torque wrench to pre-tighten the threads at each connection to deform the sealing ring, thus achieving a seal. If there are remaining test interfaces, use plugs to pre-tighten the threads for sealing. Through these steps, all 5-pressure core test assemblies to be tested can be sealed. Then, connect the external liquid phase pipeline (measuring medium) to the hydraulic connector and pre-tighten the threads. The measuring medium acts on the pressure core's pressure-sensing interface through the internal pipeline of the test device. According to the hydraulic transmission principle, this ensures that the pressure applied to each pressure core is consistent, thus enabling batch testing. Simultaneously, for more intuitive pressure observation, an external pressure gauge can be connected to test interfaces 1-3 to monitor pressure changes in real time. Because the interface connections of the test device are sealed through thread pre-tightening and welding, the sealing reliability is high, meeting the testing requirements for a large range and wide temperature range.

[0022] In this embodiment, when using the device of the present invention to measure the pressure of the pressure core using a gas medium, firstly, the 5-2 adapter sealing ring, the 5-3 pressure core, and the 5-4 adapter plug are sequentially installed into the inner cavity of the 5-1 adapter, completing the installation of the pressure core testing assembly. Then, the 1 pressure core testing base assembly is placed on the workbench for easy operation. Next, Figure 2Any test interface serves as an air inlet, used to connect to an external gas phase pipeline (measuring medium). Next, place the sealing ring into the sealing ring mounting position of test interfaces 1-3. Then, install the 5-pressure core test assembly into the test interface, completing the installation of all 5-pressure core test assemblies to be tested in sequence. Use a torque wrench to pre-tighten the threads at each connection to deform the sealing ring, thus achieving a seal. If there are remaining test interfaces, use plugs to pre-tighten the threads for sealing. Through these steps, all 7-pressure core test assemblies to be tested can be sealed. Then, connect the external gas phase pipeline (measuring medium) to the (quick-connect) pneumatic connector. The measuring medium acts on the pressure core's pressure sensing interface through the internal pipeline of the testing device. According to the pneumatic transmission principle, this ensures that the pressure applied to each pressure core is consistent, thus enabling batch testing. Simultaneously, for more intuitive pressure observation, an external pressure gauge can be installed in test interfaces 1-3 to monitor pressure changes in real time.
