Description

Technical Field

[0001] This utility model relates to the technical field of pneumatic valve testing equipment, specifically a pneumatic valve performance testing equipment. Background Technology

[0002] Pneumatic control valves are various pneumatic components in a pneumatic system that control the pressure, flow rate, and direction of airflow, ensuring the normal operation of pneumatic actuators or mechanisms. Currently, when diagnosing malfunctions in pneumatic control valves, we are easily influenced by other components in the pneumatic control system, which may lead to inaccuracies. Furthermore, after repairing and maintaining a faulty pneumatic control valve, there is no equipment to test whether its function has been fully restored. Both of these situations rely on the experience of maintenance personnel for judgment, and different personnel have different abilities and experience, resulting in significant differences in judgment efficiency and results. To improve efficiency and ensure maintenance effectiveness, a pneumatic control valve testing device needs to be designed.

[0003] CN221925615U discloses a pneumatic valve testing device, including a base, a housing fixed to the upper surface of the base, a quick-fixing assembly for fixing the pneumatic valve under test on one side of the housing, a pressure regulating device inside the housing, and a power switch on the surface of the housing. One end of the power switch is connected to a power interface embedded in the surface of the housing. This invention enables standardized and efficient testing of pneumatic valves after fault diagnosis and repair, avoiding repetitive work that results in unusable valves due to improper installation. Through the power interface, two branch pipes connecting to the air source, and the inclusion of a control ball valve and a working ball valve, the device can test electromagnetic, manual, and pneumatically controlled pneumatic valves, covering a wide range of testing types.

[0004] However, after the device completes the test on the pneumatic control valve, the pneumatic control valve to be tested needs to be replaced before the next test can be performed, resulting in a long interval between the two tests and greatly reducing work efficiency. Utility Model Content

A lead screw is rotatably mounted within the transmission cavity, and a first transmission slider is threaded onto the lead screw. A testing instrument is mounted on the top of the first transmission slider. Four support feet protrude from the bottom of the device body. A handwheel is provided at one end of the lead screw extending to the outside. A control panel electrically connected to the servo motor and the testing instrument is provided on the device body. A connecting pipe protrudes from the testing instrument and can be connected to the inlet and outlet pipes of the pneumatic valve.

[0012] Preferably, the clamping mechanism has two symmetrical connecting lugs protruding from it, and the connecting lugs are fixed to the rotating disk by fixing bolts.

[0013] Compared with the prior art, this utility model provides a pneumatic valve performance testing device with the following advantages: This utility model, through its rotating disk and clamping mechanism, allows multiple pneumatic valves to be tested to be sequentially fixed on multiple clamping mechanisms on the rotating disk.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-4A pneumatic valve performance testing device includes a main body 1 and a protective tube body. A servo motor 23 is installed on the main body 1. A rotating disk 8 is mounted on the output shaft of the servo motor 23. Multiple clamping mechanisms 9 are detachably connected to the rotating disk 8. A mounting block 4 is detachably connected to the top of the main body 1. A transmission cavity 13 is opened on the mounting block 4. A lead screw 14 is rotatably installed in the transmission cavity 13. A first transmission slider 15 is threadedly connected to the lead screw 14. A testing instrument 5 is installed on the top of the first transmission slider 15. Four support feet 2 protrude from the bottom of the main body 1. A handwheel 7 is provided at one end of the lead screw 14 extending to the outside. A control panel 3 is provided on the main body 1 and electrically connected to the servo motor 23 and the testing instrument 5. A connecting pipe 6 protrudes from the testing instrument 5 and can be connected to the air inlet and outlet pipes of the pneumatic valve.

[0020] With the provided rotating disk 8 and clamping mechanism 9, multiple pneumatic control valves to be tested can be sequentially fixed on the multiple clamping mechanisms 9 on the rotating disk 8. When the testing instrument 5 has finished testing the pneumatic control valve and needs to replace the pneumatic control valve to be tested, the servo motor 23 can be started through the control panel 3. The servo motor 23 then drives the rotating disk 8 to rotate, thereby moving the pneumatic control valve to be tested on the adjacent clamping mechanism 9 on the rotating disk 8 to the front of the testing instrument 5 for testing. During the testing process, the tested pneumatic control valve can be replaced with the pneumatic control valve to be tested, which greatly shortens the interval time between two testing processes and thus improves the testing efficiency.

[0021] Specifically, in this embodiment, a motor slot 22 is provided on the main body 1 of the device, and a servo motor 23 is disposed in the motor slot 22.

[0022] Specifically, in this embodiment, a support ring 20 is provided on the top of the main body 1 of the device, and a plurality of support rollers 21 are provided on the top of the support ring 20 at intervals along the circumferential direction. The bottom surface of the rotating disk 8 is in contact with the plurality of support rollers 21, which can provide support for the rotating disk 8 while reducing the friction between the support structure and the rotating disk 8.

[0023] Specifically, in this embodiment, a fixed gripper 10 protrudes from the clamping mechanism 9, and a threaded rod 16 is rotatably mounted on the clamping mechanism 9. A second transmission slider 17 is threadedly connected to the threaded rod 16, and a movable gripper 11 is provided on the top of the second transmission slider 17. An arc-shaped groove 19 is provided on the side where the fixed gripper 10 and the movable gripper 11 are close to each other. The movable gripper 11 can be moved toward the fixed gripper 10 by rotating the threaded rod 16 through the threaded screwing relationship, thereby realizing the clamping and fixing of the pneumatic control valve to be tested.

[0024] Specifically, in this embodiment, both the fixed gripper 10 and the movable gripper 11 are provided with U-shaped grooves 18 through which the air inlet pipe and air outlet pipe of the pneumatic control valve can pass. The position of the U-shaped grooves 18 is set according to the different models of the pneumatic control valve to be tested, which can facilitate the clamping and fixing of different models of pneumatic control valves and reduce the obstruction of the clamping mechanism 9 to the pneumatic control valve testing process.

[0025] Specifically, in this embodiment, the clamping mechanism 9 is provided with two symmetrical connecting ear plates 12. The connecting ear plates 12 are fixed to the rotating disk 8 by fixing bolts 24, which makes it easy to replace the clamping mechanism 9. When testing different models of pneumatic control valves, the clamping mechanism 9 that is compatible with the position of the inlet pipe and outlet pipe of the pneumatic control valve can be replaced, thereby improving the adaptability of the device.

[0026] It should be noted that the testing instrument is electrically connected to the servo motor and the mains power, and the more detailed structure, working principle and usage of the servo motor and the testing instrument are the same as those in the prior application of a pneumatic valve testing device disclosed in patent number CN221925615U, so this application will not repeat them.
