[0042] Please refer to Figure 3 , the vacuum steam pressure test device 100 further includes a controller (not shown in the figure). The vacuum pump 60, the steam generator 30, the first solenoid valve 70, and the second solenoid valve 80 are all electrically connected to the controller.

[0043] Please refer to Figure 3 , the vacuum steam pressure test device 100 further includes a drain pump 90. The drain pipe is connected to the drain pump 90, and the water in the vacuum test device is drained through the drain pump 90. The drain pump 90 is electrically connected to the controller.

[0046] Please refer to Figure 3 , the vacuum steam pressure test device 100 further includes a safety valve 130. The safety valve 130 is arranged on the vacuum test tank 20. When the pressure value in the vacuum test tank 20 reaches the critical pressure value of the vacuum test tank 20, the safety valve 130 opens to relieve pressure, thereby effectively improving the safety performance of the vacuum steam pressure test device 100.

[0047] Please refer to Figure 1, the vacuum steam pressure test device 100 further includes rollers 40 and feet 50. The rollers 40 are provided below the box body 10, and the feet 50 are screwed to the box body 10. By rotating the feet 50 and extending the feet 50 downward to support the rollers 40, the vacuum steam pressure test device 100 can be fixedly placed on the floor. When the feet 50 are rotated to contract upward and the rollers 40 contact the floor, the vacuum steam pressure test device 100 can be moved, which is convenient for users.

[0048] The working principle of the vacuum steam pressure test device 100 in this embodiment: During operation, the staff places the test sample in the vacuum test tube, and then sets the temperature threshold and pressure threshold required for the test. When conducting a test that requires steam participation, the controller controls the first solenoid valve 70 to open, and the steam in the steam generator 30 enters the vacuum test tank 20 through the steam inlet pipe.

[0049] When the temperature value measured by the temperature sensor 110 is greater than the temperature threshold stored in the controller, the controller controls the first solenoid valve 70 to close. When the pressure value measured by the pressure sensor 120 in the vacuum test tank 20 is not less than the pressure threshold stored in the controller, the controller controls the first solenoid valve 70 to open. In the actual application process, when the temperature value measured by the temperature sensor 110 is greater than the temperature threshold stored in the controller, and the pressure value measured by the pressure sensor 120 in the vacuum test tank 20 is less than the pressure threshold stored in the controller, the controller preferentially controls the first solenoid valve 70 to close. When the temperature value in the vacuum test tank 20 is not greater than the temperature threshold, the controller controls the first solenoid valve 70 to open; when the temperature value measured by the temperature sensor 110 is greater than the temperature threshold stored in the controller, and the pressure value measured by the pressure sensor 120 in the vacuum test tank 20 is greater than the pressure threshold stored in the controller, the controller controls the first solenoid valve 70 to close.

[0050] When the temperature value measured by the temperature sensor 110 is less than the temperature threshold stored in the controller, and the pressure value measured by the pressure sensor 120 in the vacuum test tank 20 is greater than the pressure threshold stored in the controller, the controller controls the first solenoid valve 70 to remain open and simultaneously controls the vacuum pump 60 to start.

[0051] After the steam pressure test is completed, the controller controls the first solenoid valve 70 and the vacuum pump 60 to close, and the controller controls the second solenoid valve 80 to open and the drain pump 90 to open to drain the water in the vacuum test tank 20.

[0052] When the test sample needs to be tested under vacuum conditions, the controller controls the first solenoid valve 70 to remain closed, and at the same time the controller controls the vacuum pump 60 to start to evacuate the vacuum test tank 20.

[0053] The beneficial effects of the present utility model are as follows: Through the cooperation of the box body 10, the vacuum test tank 20, the vacuum pump 60 and the steam generator 30, it can not only provide a vacuum condition for the test sample, but also provide a high-pressure steam condition, enabling the test sample to complete the vacuum test and the steam high-pressure test on the vacuum steam pressure test device 100 without replacing the machine, effectively avoiding the influence brought by environmental changes and making the test data more accurate.

[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0055] The above-described embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
