The hot water pipe 4 and the cold water pipe 3 are controlled to enter and exit the hot and cold water through the first solenoid valve 5 and the second solenoid valve 6, so as to achieve the goal of keeping cold water or hot water in the test cylinder 8 for testing. The water pump 12 is switched on and off at the same time with the first solenoid valve 5, and the hot water after the test in the test cylinder 8 is controlled to flow into the water heater 1 through the recovery pipe 14. The water pump 2 13 is linked with the second solenoid valve 6 at the same time, and the cold water after the test in the test cylinder 8 is controlled to flow into the water cooler 2 through the recovery pipe 2 15 for subsequent testing, so as to solve the problem that after the rapid cooling and heating shock test, water needs to be added again, and the water needs to be heated or cooled again before the test, so that the device has high cost performance, energy saving and environmental protection when used.

[0026] Further, such as Figure 1 and Figure 2As shown, the other end of the recovery pipe 14 is connected to the water heater 1; the water outlet end of the recovery pipe 2 15 is fixedly connected to the water cooler 2; the top of the test tube 8 is fixedly connected to a pressure gauge 21 and a temperature detection module 20; the detection end of the temperature detection module 20 is arranged in the test tube 8; the test door 22 is fixedly connected to a scale 19.

[0028] Further, such as Figure 4As shown, the test cylinder 8 is connected with a descaling device 9; the descaling device 9 includes a driving motor 901; a driving shaft 902 is fixedly connected to the driving motor 901; the driving shaft 902 is rotatably connected to the top of the test cylinder 8; three fixed brackets 903 are fixedly connected to the driving shaft 902; a scraper 904 is fixedly connected to the fixed bracket 903; the scraper 904 is attached to the inner wall of the test cylinder 8. When descaling, cleaning water is introduced into the test cylinder 8, and then the driving motor 901 drives the driving shaft 902 The driving shaft 902 rotates and drives the fixed bracket 903 and the connected scraper 904, so that the fixed bracket 903 and the scraper 904 drive the cleaning water in the test tube 8 to rotate, and the impact force of the water flow is used to soften and fall off the impurities attached to the inner wall of the test tube 8, and then the scraper 904 scrapes the inner wall of the test tube 8 to clean the residual impurities on the inner wall of the test tube 8, and the cleaned water is discharged through the interface assembly 16 on the recovery pipe 14, thereby cleaning the inner wall of the test tube 8, thereby reducing the influence of impurities on the accuracy of the sanitary ware resistance to rapid cooling and heating shock test during the test.

[0030] Further, such as Figure 1 As shown, a fixed base 17 is fixedly connected to the bottom of the test cylinder 8; three anti-skid pads 18 are arranged on the fixed base 17.

[0031] Working principle: during operation, the three-way valve 7 is synchronized with the first solenoid valve 5 and the second solenoid valve 6. When the first solenoid valve 5 is opened, the connection position of the first solenoid valve 5 and the three-way valve 7 is opened, and the connection position of the second solenoid valve 6 and the three-way valve 7 is closed; when the second solenoid valve 6 is opened, the connection position of the first solenoid valve 5 and the three-way valve 7 is closed, and the connection position of the second solenoid valve 6 and the three-way valve 7 is opened. At the same time, the water pump 12 is switched on and off with the first solenoid valve 5, and the water pump 2 13 is linked with the second solenoid valve 6 at the same time. The first solenoid valve 5 and the second solenoid valve 6 are used to control the hot and cold water inlet and outlet of the hot and cold water pipes 4 and 3, so as to keep cold water or hot water in the test cylinder 8 for testing. The water pump 12 is switched on and off with the first solenoid valve 5 at the same time, so as to control the heat in the test cylinder 8 after the test. Water flows into the water heater 1 through the recovery pipe 14, and the water pump 2 13 is linked with the second solenoid valve 6 at the same time, thereby controlling the cold water after the test in the test tube 8 to flow into the water cooler 2 through the recovery pipe 2 15 for subsequent tests, so as to solve the problem that after the rapid cold and heat shock test, water needs to be added again, and the water needs to be reheated or cooled before the test, so that the device has high cost performance, energy saving and environmental protection when used. When the sanitary ware is subjected to the rapid cold and heat shock test, the cold and hot water flows into the hot water pipe 4 or the cold water pipe 3 through the water cooler 2 and the water heater 1, and the switch is controlled by the first solenoid valve 5 and the second solenoid valve 6, so that the cold and hot water used for the test enter the test tube 8 through the three-way valve 7, and the sanitary ware in the test tube 8 is subjected to the rapid cold and heat shock test. The detection module 20 detects the temperature in the test cylinder 8. When the temperature in the test cylinder 8 is too high or too low, the first solenoid valve 5 and the second solenoid valve 6 cooperate to control the amount of hot and cold water entering the test cylinder 8, so that the temperature in the test cylinder 8 is more accurate, so that when the sanitary ware is subjected to the rapid cold and hot shock test, the test data is more accurate, and the test accuracy is improved. The pressure gauge 21 can detect the pressure value in the test cylinder 8, and the scale 19 can see the water level in the test cylinder 8 at any time.

When descaling, cleaning water is introduced into the test tube 8, and then the driving motor 901 drives the driving shaft 902 to rotate. The driving shaft 902 drives the fixed bracket 903 and the connected scraper 904, so that the fixed bracket 903 and the scraper 904 drive the cleaning water in the test tube 8 to rotate, and the impact force of the water flow is used to soften and fall off the impurities attached to the inner wall of the test tube 8, and then the scraper 904 scrapes the inner wall of the test tube 8 to clean the residual impurities on the inner wall of the test tube 8. The cleaned water is discharged through the interface assembly 16 on the recovery pipe 14, and then the inner wall of the test tube 8 is cleaned, so as to reduce the influence of impurities on the accuracy of the sanitary ware resistance to rapid cold and heat shock test during the test.The driving motor 901 drives the driving shaft 902 to rotate, and the driving shaft 902 drives the connected fixed shaft 906 to rotate, and then drives the cleaning rod 907 and the auxiliary rod 908 fixed by the fixed shaft 906 to rotate, and the rotating cleaning rod 907 scrapes the bottom of the test tube 8, and then cleans the bottom of the test tube 8, so that the cleaning of the test tube 8 is cleaner and the cleaning effect is improved. By setting the fixed base 17 and the anti-skid pad 18, when using the device, the bearing capacity of the test tube 8 is improved by the fixed base 17, and the anti-skid pad 18 reduces the large movement of the test tube 8 during operation, so that the test tube 8 is more stable when in use.
