[0029] Example 2:

[0030] See also Figures 1 to 6 , a solenoid valve performance testing device and thermal deformation detection method under high temperature environment of the present invention, compared with embodiment 1, this embodiment also includes: a surface detection component 27 includes a magnetic material 271 fixedly arranged at the end of the multi-arm robot 26, and the magnetic material 271 is specifically composed of a neodymium iron boron magnet; the magnetic material 271 is fixedly installed on the bottom of the heat exchange box 272 by bolts, and quick-connect valve ports 273 are plugged and fixed on both sides of the heat exchange box 272; a second heat insulation box 274 is fixedly installed on the top of the heat exchange box 272 by bolts, and a sensor 275 is fixedly installed inside the second heat insulation box 274; the sensor head at the bottom of the sensor 275 passes through the magnetic material 271 and the heat exchange box 272, and the outer side of the end of the sensor head of the sensor 275 is sleeved with hard rubber with a protective function.

[0032] The working principle of the solenoid valve performance testing device and thermal deformation detection method under high temperature environment is as follows: First, when using this device, first place the device in the working area, then connect the device to an external power source to provide the power required for the device to work; Second, the staff controls the external pressure regulating device through the control panel 4 to adjust the pressure inside the pressure cylinder 23, thereby pulling the two sets of adsorption sliders 22 through the pressure cylinder 23 to adjust the spacing. Then the staff places the solenoid valve to be tested between the two sets of connecting components 24. Here, the staff controls the servo motor 2441 to drive the gear box 2442 to engage with the rotating disk 2443, so that the second moving block 2445 inside the rotating disk 2443 drives the first moving block 2431 to move synchronously through the connecting rod. During the displacement of the first moving block 2431, the memory metal 2432 is driven to form a trumpet-shaped connecting pipe with the fixed ring 2433 at its tail. The opening and closing component 244 is adjusted to adapt to the pipe connection of solenoid valves of different specifications. Third, while the performance test is being conducted inside the regulating assembly 243, high-pressure fluid flows through it. At this time, the fluid is introduced into the first barrier cloth 242 through the valve on the side of the first heat-insulating box 241, thereby forming a high-pressure environment around the second barrier cloth 2434. This prevents the second barrier cloth 2434 from deforming due to the increased fluid pressure inside, which would affect the flow rate of the fluid. The multi-arm robot 26 then moves along the linear guide rail 25, and the surface detection assembly 27 at its end is attracted and directly contacts the surface of the solenoid valve to complete the clamping and fixing action. Fourth, after the installation of the solenoid valve is completed, a high temperature environment is simulated inside the upper cavity of the test bench 1 through two sets of temperature control boxes 3 at the bottom of the test bench 1. Here, the full-field deformation of the surface of the solenoid valve body is measured by the sensor 275 inside the second heat insulation box 274, and the temperature distribution is monitored synchronously by infrared thermal imaging through the scanning camera at the end of the multi-arm robot 26. The heat exchange fluid is introduced into the heat exchange box 272 through the cooling flow channel of the quick-connect valve port 273 to cooperate with the temperature sensor for dynamic temperature control to ensure the operating temperature of the surface detection component 27 is stable, establish a temperature-deformation correspondence to realize synchronous temperature monitoring, use the second heat insulation box 274 and the heat exchange box 272 and the first blocking cloth 242 to block thermal radiation, actively dissipate heat to protect the sensor 275, and centrally process the collected temperature data through the control panel 4 to generate a temperature-deformation curve and a three-dimensional deformation map to evaluate the high-temperature performance of the solenoid valve.

[0033] The present invention provides an improved solenoid valve performance testing device and thermal deformation detection method under high-temperature environment. Through the adjustment effect of the adjustment component 243 and the opening and closing component 244, combined with the deformation characteristics of the memory metal 2432, an adjustable trumpet-shaped connecting pipe structure is formed, which realizes adaptive sealing connection of the pipe mouths of solenoid valves of different specifications and solves the multi-size compatibility problem; the high-temperature environment is simulated by the temperature control box 3, combined with infrared thermal imaging and surface detection component 27, the temperature distribution and deformation data are collected in real time, and a temperature-deformation correspondence map is established to realize accurate evaluation of the high-temperature performance of the solenoid valve. The control panel centrally processes data, generates a three-dimensional deformation map and temperature curve, and realizes intelligent closed-loop control of the detection process.
