Description

Technical Field

[0001] This utility model relates to the technical field of valve temperature and pressure component testing equipment, specifically a valve temperature and pressure component testing device. Background Technology

[0002] In the testing of valve temperature and pressure components, traditional testing fixtures typically require the sensor to be directly connected to the test board. This direct connection method has significant drawbacks in practical operation: 1. Frequent plugging and unplugging of interfaces: Because the testing process requires frequent connection and disconnection of the sensor and test board, the interfaces are prone to loosening under these frequent plugging and unplugging actions. Loose interfaces directly lead to poor contact, resulting in test failures. This not only affects testing efficiency but may also cause misjudgments, posing safety hazards to subsequent valve use.

[0003] 2. High risk of test board damage: Severe interface damage may cause the solder pads on the test board to detach. Pad detachment often means the entire test board is unusable and requires replacement with a completely new one. As a core component of testing fixtures, the test board has high replacement costs; frequent replacements significantly increase a company's testing costs, hindering cost control and economic efficiency.

[0004] Therefore, improvements are needed to address the aforementioned technical issues. Utility Model Content

[0005] The purpose of this invention is to provide a valve temperature and pressure component testing device that transfers physical wear to a replaceable adapter board, protects the lifespan of the main control board, and reduces maintenance costs, thereby solving the problems mentioned in the background art, such as frequent plugging and unplugging of interfaces leading to loosening, solder pad detachment, and high cost of replacing test boards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve temperature and pressure component detection device, comprising a base, a top cover, a main control board, a connecting wire, and an adapter plate; the base and the top cover are detachably connected, forming a positioning cavity between the base and the top cover, the main control board is built into the positioning cavity, and the adapter plate is mounted on the top cover, wherein the adapter plate is a replaceable structure, and the two ends of the connecting wire are respectively connected to the main control board and the adapter plate to realize data and signal transmission between the main control board and the adapter plate; the valve temperature and pressure sensor is connected to the detection device through the adapter plate, and the adapter plate is used to bear the physical wear caused by the insertion and removal of the valve temperature and pressure sensor interface.

[0007] The advantages of the above-mentioned basic structure design are as follows: By embedding the main control board within the positioning cavity formed by the base and the top cover, the main control board is prevented from being directly exposed to the external environment, reducing the corrosion of the main control board by dust, moisture, and other impurities, while also preventing physical damage to the main control board from external impacts; the adapter board and the main control board are indirectly connected via a connecting cable, and during testing, only the valve temperature and pressure component needs to be connected to the adapter board, so that the physical wear of the interface plugging and unplugging is concentrated on the adapter board. When the adapter board is severely worn, only the adapter board needs to be replaced, without replacing the more expensive main control board, which greatly reduces maintenance costs; in addition, the detachable connection design of the base and the top cover makes it easy to open the device for inspection when the main control board fails, improving the convenience of equipment maintenance.

[0008] Furthermore, a guide groove is formed on the upper cover, and the adapter plate is built into the guide groove. The adapter plate and the upper cover are fastened together by bolts. The guide groove can accurately position the installation position of the adapter plate, avoid the adapter plate from shifting during assembly, ensure the docking accuracy between the adapter plate and the connecting line, and reduce signal transmission deviation caused by the positional shift of the adapter plate. At the same time, the guide groove can provide circumferential restraint for the adapter plate, prevent the adapter plate from shifting due to vibration or external force during the testing process, and ensure the stability of the testing process. The bolt fastening method not only ensures the firmness of the connection between the adapter plate and the upper cover, but also allows for quick replacement of the adapter plate by removing the bolts after the adapter plate wears down, further improving the convenience of adapter plate replacement and shortening equipment downtime for maintenance.

[0009] Furthermore, a guide hole is formed near the guide groove on the top cover for the connecting wire to pass through. The guide hole provides a dedicated passage for the connecting wire, which can regulate the direction of the connecting wire, prevent the connecting wire from being randomly tangled inside the device, and prevent signal transmission interference or wire wear caused by the tangled connecting wire. At the same time, the guide hole can limit the connection end of the connecting wire to the adapter board in a specific area, reducing the risk of the connecting wire becoming loose from the adapter board or main control board due to external force pulling during the detection process, ensuring the stability of the circuit connection, and thus improving the reliability of the detection data.

[0010] Furthermore, the guide hole has an arc-shaped structure around its perimeter. This arc-shaped structure prevents the edges of the guide hole from forming sharp corners, preventing the connecting wire from being scratched by the edge of the hole during installation or long-term use, reducing wear on the wire insulation layer, and lowering the risk of short circuits caused by damage to the wire insulation layer. At the same time, the arc-shaped structure can disperse the contact stress between the connecting wire and the edge of the hole, preventing the wire from breaking due to local stress concentration, extending the service life of the connecting wire, and reducing equipment failures caused by damage to the connecting wire.

[0011] Furthermore, the adapter board has a connection adapter socket and a detection adapter socket. The connection adapter socket connects to the connecting cable, and the detection adapter socket connects to the valve temperature and pressure assembly via a wire. By separating the interface functions of the adapter board into the connection adapter socket and the detection adapter socket, the functions of "internal connection" and "external detection" are separated: the connection adapter socket only connects to the connecting cable when the adapter board is replaced, with a low frequency of connection and low wear; the detection adapter socket, on the other hand, handles high-frequency connection with the valve temperature and pressure assembly, with wear concentrated on this socket, further clarifying the wear location and facilitating targeted maintenance. At the same time, the functional separation design allows different interfaces to be selected according to usage requirements. The connection adapter socket can use a highly stable interface to ensure the signal transmission quality with the main control board, while the detection adapter socket can use a highly wear-resistant interface to improve service life, thereby improving the overall adaptability and reliability of the device.

[0012] Furthermore, the detection adapter socket is made of wear-resistant material. Since the detection adapter socket needs to be frequently plugged and unplugged with the valve temperature and pressure component, it is the component with the most concentrated wear in the entire device. Using wear-resistant materials (such as brass alloys, engineering plastics and metal inserts) can significantly improve the wear resistance of the detection adapter socket, extend its service life, and reduce the replacement frequency caused by wear of the detection adapter socket. At the same time, the surface hardness of the wear-resistant material is higher, which can reduce the coefficient of friction during the plugging and unplugging process and reduce the plugging and unplugging resistance. This not only makes it easier for operators to perform docking operations, but also reduces the wear on the valve temperature and pressure component interface during plugging and unplugging, thereby protecting the object being tested.

[0013] Furthermore, the connecting line uses a conductor with anti-interference properties, and the outer layer of the conductor is wrapped with a shielding layer to reduce the interference of external electromagnetic signals on the data transmitted between the main control board and the adapter board. During the valve temperature and pressure component testing process, the detection data (such as pressure signals, temperature signals, etc.) transmitted between the main control board and the adapter board are usually weak electrical signals, which are easily affected by the external electromagnetic environment, resulting in data distortion and affecting the detection accuracy. The conductor with anti-interference properties and the outer shielding layer (such as copper mesh shielding layer, aluminum-plastic composite shielding layer, etc.) can effectively block the intrusion of external electromagnetic signals, reduce the impact of electromagnetic interference on the transmitted data, and ensure the accuracy and stability of the detection data. At the same time, the shielding layer can also prevent the signal transmitted by the connecting line itself from radiating outward, avoid causing electromagnetic interference to other surrounding equipment, and improve the compatibility of the equipment in scenarios where multiple detection devices are working simultaneously.

[0014] Furthermore, the base has lower lugs on both sides, and correspondingly, the top cover has upper lugs on both sides. The lower and upper lugs are fixed together by screws. This corresponding design distributes the stress on the connection between the base and the top cover to the lugs on both sides, preventing stress concentration at the edges of the base or top cover, reducing deformation caused by stress concentration, and extending the service life of the device casing. The screw fixing method not only provides a secure connection but also allows for quick disassembly and assembly of the base and top cover by removing the screws, facilitating the operator's inspection or replacement of internal components such as the main control board and connecting wires, thus improving equipment maintenance efficiency. In addition, the lug design increases the contact area between the base and the top cover, further enhancing the overall structural stability of the device and preventing internal components from shifting due to loosening of the device casing during testing.

[0015] Furthermore, the base has a circumferentially oriented limiting protrusion at its top and a circumferentially oriented limiting groove at its bottom. When the base and the top cover are assembled, the limiting protrusion is embedded in the limiting groove. The fitting structure of the limiting protrusion and the limiting groove can play a precise guiding role during the assembly of the base and the top cover, ensuring that the base and the top cover can be quickly aligned and improving assembly efficiency. At the same time, the fitting structure can provide circumferential limiting for the base and the top cover, preventing relative rotation between the base and the top cover after assembly, and ensuring the integrity and stability of the device housing. In addition, the fitting structure can also enhance the sealing performance between the base and the top cover, reducing the entry of external dust, moisture and other impurities into the positioning cavity through the gap between the base and the top cover, further protecting internal components such as the main control board and extending their service life.

[0016] Furthermore, the top cover is made of a transparent material; the transparent material allows operators to directly observe the working status of the internal main control board, connecting wires, and adapter boards without opening the device. For example, it allows for a direct assessment of whether the connecting wires are loose, whether the adapter boards have shifted, and whether the indicator lights on the main control board are functioning normally. This facilitates timely detection of equipment abnormalities, reduces the number of times the device needs to be opened for troubleshooting, and improves fault response efficiency. At the same time, the transparent top cover also allows operators to easily observe the mating of internal components during assembly, ensuring assembly accuracy and reducing the assembly error rate.

[0017] The beneficial effects of this utility model are: This utility model is ingeniously designed. By adding a replaceable modular adapter board, the physical wear caused by frequent plugging and unplugging of the interface is transferred to the adapter board instead of directly affecting the core main control board, thereby protecting the service life of the main control board. At the same time, by replacing the entire main control board with a low-cost adapter board, maintenance costs are significantly reduced. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0021] Example

[0022] like Figures 1-4 As shown, a valve temperature and pressure component detection device includes a base 1, an upper cover 2, a main control board 3, a connecting line 4, and an adapter plate 5. The base 1 and the upper cover 2 are detachably connected, and a positioning cavity 6 is formed between the base 1 and the upper cover 2. The main control board 3 is built into the positioning cavity 6, the adapter plate 5 is assembled on the upper cover 2, and the two ends of the connecting line 4 are connected to the main control board 3 and the adapter plate 5 respectively.

[0023] In this embodiment, both the base 1 and the top cover 2 are made using 3D printing technology and are made of ABS engineering plastic, which combines lightweight and high strength characteristics, effectively reducing the overall weight of the device while ensuring the structural strength of the shell; the main control board 3 adopts a conventional single-chip microcomputer control board, integrating pressure signal acquisition, data processing and transmission functions; the connecting cable 4 adopts RVVP shielded wire with copper mesh shielding layer to improve anti-interference performance; the adapter board 5 uses FR-4 epoxy resin board as the substrate, and the adapter socket 50 and the detection adapter socket 51 are welded to the surface.

[0024] like Figure 2 As shown, a guide groove 20 is formed on the upper cover 2, and the adapter plate 5 is built into the guide groove 20. The adapter plate 5 and the upper cover 2 are fastened by bolts 21. The size of the guide groove 20 is adapted to the size of the adapter plate 5, and the tolerance is controlled within ±0.1mm to ensure that the adapter plate 5 can be accurately embedded without loosening. The bolts 21 are M3 cross countersunk screws to avoid the bolt heads protruding and affecting the appearance of the device or scratching the operators.

[0025] The top cover 2 has a guide hole 22 near the guide groove 20 for the connecting wire 4 to pass through. The diameter of the guide hole 22 is larger than the outer diameter of the connecting wire 4, which facilitates the insertion of the connecting wire 4 and prevents the connecting wire 4 from shaking excessively in the hole. The guide hole 22 has an arc-shaped structure around it, which effectively prevents the wire insulation layer from being scratched.

[0026] like Figure 3 As shown, the connection adapter socket 5 on the adapter plate 5 is adapted to the terminal of the connection line 4; the test adapter socket 51 is made of brass and has a nickel-plated surface to improve wear resistance and conductivity. The specifications of the test adapter socket 51 are adapted to the interface model of the temperature and pressure component of the valve to be tested.

[0027] like Figures 5-6 As shown, the base 1 has lower lugs 10 on both sides, and the upper cover 2 has upper lugs 23 on both sides. Both the lower lugs 10 and the upper lugs 23 have threaded holes and are fixed by screws. The top of the base 1 has a 2mm high limiting protrusion 11, and the bottom of the upper cover 2 has a 2mm deep limiting groove 24. The cross-sections of the limiting protrusion 11 and the limiting groove 24 are both rectangular to ensure a tight fit.

[0028] The top cover 2 is made of transparent acrylic sheet with a thickness of 3mm, which makes it easy for operators to observe the condition of internal components; at the same time, the surface of the transparent acrylic sheet is covered with a scratch-resistant film to reduce scratches during use and ensure long-term light transmittance.

[0029] In this embodiment, the valve temperature and pressure component testing device first connects the valve temperature and pressure component interface to the testing adapter socket 51 on the adapter plate 5. After starting the device, the main control board 3 sends a testing command to the adapter plate 5 via the connecting cable 4 and receives the valve temperature and pressure component testing data transmitted by the adapter plate 5, thus completing the pressure performance test. When the testing adapter socket 51 becomes worn or has poor contact due to long-term plugging and unplugging, it is only necessary to remove the bolts 21 on the top cover 2 and replace the new adapter plate 5 to restore its use. There is no need to replace the main control board 3, which significantly reduces maintenance costs. In addition, the transparent top cover 2 allows real-time observation of the internal component status, making it easy to detect abnormalities such as loose connecting cables 4 in a timely manner, thereby improving the reliability and stability of the testing process.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0031] Although this document frequently uses reference numerals from the accompanying drawings, such as base 1, top cover 2, main control board 3, connecting line 4, adapter plate 5, positioning cavity 6, lower lug structure 10, limiting protrusion 11, guide groove 20, bolt 21, guide through hole 22, upper lug structure 23, limiting groove 24, connecting adapter socket 50, and detection adapter socket 51, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
