The surface of the fixture 14 on the side of the first side water inlet product positioning groove 142 is also provided with a slot 143. There are two or more slots 143. The slots 143 and the first side water inlet product positioning groove 142 are used for positioning the side water inlet product. The surface of the product sealing core body 144 is provided with water and gas inlets and outlets 148. The water and gas inlets and outlets 148 are used for the entry and exit of water and gas during testing. An assembly tube 17 is provided at the bottom of the fixture 14. The assembly tube 17 is connected to the interior of the product sealing core body 144. The surface of the assembly tube 17 is threaded. A detachable detection pipeline 18 is connected to the device. A pressure sensor 110, which can be a MEMS resistive pressure sensor, is mounted on the surface of the detection pipeline 18.

A bottom-inlet product body 15 is provided on the surface of the product sealing core body 144.The interior of the bottom-inlet product body 15 is connected to the water and air inlet / outlet 148.

[0024] Furthermore, such as Figure 2 and Figure 5 As shown, lifting components 2 are provided on the surfaces of the frame plate 12 and the lifting plate 13. The lifting components 2 consist of a motor 21, a rotating shaft 22, a lifting rod 23, a driving pulley 24, a driven pulley 25, a belt body 26, a connecting frame 27, a support frame 28, and a guide frame 29. The motor 21 is mounted on the surface of the frame plate 12. The input end of the motor 21 is electrically connected to the output end of the controller 11. The output end of the motor 21 is mounted on the rotating shaft 22 through a coupling. Two sets of support frames 28 are symmetrically mounted on the surface of the frame plate 12. The inner side of the support frame 28 is provided with a rotating driving pulley 24. The surface of the pulley 24 is fixed to the surface of one end of the shaft 22. Two sets of connecting frames 27 are symmetrically arranged on the surface of the frame plate 12. A driven pulley 25 is arranged on the inner side of the connecting frame 27. A belt body 26 is fitted on the surface of the driven pulley 25 and the driving pulley 24. A lifting rod 23 is arranged on the surface of the connecting frame 27. The lifting rod 23 slides with the surface of the connecting frame 27. The lifting rod 23 slides with the inner wall of the guide frame 29. The surface of the belt body 26 is fixed to the surface of the lifting rod 23. The surface of the lifting rod 23 is fixed to the surface of the rear side of the lifting plate 13.

[0025] During implementation, the control motor 21 operates, driving the rotating shaft 22 to rotate. When the rotating shaft 22 rotates, it drives the drive pulley 24 on the inner wall of the support frame 28 to rotate. When the drive pulley 24 rotates, it drives the belt body 26 to drive the driven pulley 25 to rotate on the inner wall of the connecting frame 27. When the belt body 26 is in operation, it drives the lifting rod 23 to slide on the inner wall of the guide frame 29. At this time, the lifting rod 23 drives the lifting plate 13 to move downwards, thereby driving the surface of the lifting plate 13... Each fixture 14 and the product mounted on its surface moves downwards into the water tank 10. The product's sealing performance is tested by the pressure difference between the product and the water in the water tank 10. When the product is immersed in water, a vacuum is drawn inside through the water and air inlet / outlet 148 to create a negative pressure environment. At this time, the gas pressure inside the product is lower than the external water pressure, creating a pressure difference between the inside and outside. If the product is well sealed, no bubbles will emerge. If there is a leak, water will enter the product under the pressure difference, generating bubbles. This allows for a direct assessment of whether the sealing performance meets the standard, thus achieving the function of accurate testing by the testing equipment.

[0026] Furthermore, such as Figure 3 , Figure 4 and Figure 6As shown, the surface of the product sealing core body 144 is provided with a high compatibility mechanism 3. The high compatibility mechanism 3 includes a positioning groove 31, a limiting groove 32, and a sealing ring groove 33. The product sealing core body 144 has a limiting groove 32, a sealing ring groove 33, and a positioning groove 31 sequentially formed from top to bottom. The limiting groove 32, the sealing ring groove 33, and the positioning groove 31 are used to position the sealing rings of water inlet valve products of different diameters.

[0027] Working principle: During use, first place the equipment frame 1 in the designated position, install the product in the fixture 14, and ensure that the water and gas inlet / outlet 148 on the surface of the product sealing core body 144 is tightly connected to the corresponding interface of the product. The sealing structure on the product surface, such as the sealing ring, fixes and seals the product to the product sealing core body 144 to prevent media leakage during the test. Specifically: if the product to be tested is a bottom-inlet water product body 15, the product sealing core body 144 can rotate on the inner wall of the fixture 14, and is positioned by the first sealing core positioning top bead 145 and the second sealing core positioning top bead 145. The core positioning bead 1410 positions the product sealing core body 144. At this time, the water and gas inlet / outlet 148 is vertically upward. The user installs the bottom-inlet product body 15 on the surface of the product sealing core body 144 and tests the bottom-inlet product body 15 through the water and gas inlet / outlet 148. If the product to be tested is a side-inlet product, the water and gas inlet / outlet 148 is horizontally forward. The user installs the side-inlet product on the surface of the product sealing core body 144 and tests the side-inlet product through the water and gas inlet / outlet 148. Before testing the product, the stability of the connection between the assembly pipe 17 and the detection pipe 18 must be ensured. Water enters the interior of the water and gas inlet / outlet 148 from the detection pipe 18 and the assembly pipe 17, and then flows through the internal flow channel of the product. During testing, the product is in a closed state, and its sealing performance is evaluated by detecting whether the water flow leaks. If no leakage occurs within the specified time, the sealing performance of the inlet valve product is deemed qualified; otherwise, it is deemed unqualified. The controller 11 controls the water pump 16 to work, and the water pump 16 delivers water from the water storage tank 10 to the detection pipe 18 and the assembly pipe 17. For high-pressure flow detection, the high-pressure regulating valve of the water pump 16 is adjusted to achieve the required high-pressure value. When the water flows through the product, the flow meter 19 records the flow data at this time. For low-pressure flow detection, the water flow meter 19 is adjusted to ensure the high pressure. The low-pressure regulating valve of pump 16 is adjusted to the set pressure value. Flow data is also obtained through flow meter 19. By comparing the actual flow rate with the standard flow range, the performance of the product's high-pressure water flow rate and low-pressure water flow rate is judged to be qualified. Air enters the interior of the water and air inlet / outlet 148 from the detection pipe 18 and assembly pipe 17, and then enters the interior of the product through the water and air inlet / outlet 148, forming a stable air pressure inside the product. Pressure sensor 110 judges the leakage situation by detecting changes in air pressure. After inflation and pressure stabilization, if the air pressure drops beyond the set threshold, it is determined that the product has a leak and the sealing performance is unqualified. After the test is completed, pressure sensor 110 and flow meter 19 send signals to controller 11. Controller 11 automatically displays the test results, making it easy to quickly judge whether the sealing performance of the water inlet valve meets the standard.

[0028] Subsequently, during product testing, controller 11 controls motor 21 to operate, which in turn drives shaft 22 to rotate. When shaft 22 rotates, it drives the drive pulley 24 on the inner wall of support frame 28 to rotate. This drive pulley 24 then drives belt body 26, which in turn drives driven pulley 25 to rotate on the inner wall of connecting frame 27. As belt body 26 drives, it causes lifting rod 23 to slide on the inner wall of guide frame 29. At this time, lifting rod 23 causes lifting plate 13 to move downwards, thereby causing the fixtures 14 on the surface of lifting plate 13 and the products mounted on the fixtures 14 to move downwards. Inside the water tank 10, the product's sealing performance is tested by the pressure difference between the product and the water in the tank. When the product is immersed in water, a vacuum is created inside through the water and air inlet / outlet 148, forming a negative pressure environment. At this time, the gas pressure inside the product is lower than the external water pressure, creating a pressure difference. If the product is well sealed, no bubbles will emerge. If there is a leak, water will enter the product under the pressure difference, generating bubbles. This allows for a direct assessment of whether the sealing performance meets the standards, enabling the testing equipment to perform accurate testing. This allows the testing equipment to accurately test the inlet valve product under low-pressure water testing, high-pressure water testing, low-pressure air testing, and high-pressure air testing, eliminating misjudgments and improving product quality.

[0029] Subsequently, when installing the product on the surface of the product sealing core body 144, since the surface of the product sealing core body 144 is provided with positioning groove 31, sealing ring slot 33, and limiting groove 32, the user can select the appropriate installation position of the product according to the different diameters of the product sealing ring, so that the sealing ring on the product surface can be accurately locked onto the surface of positioning groove 31, sealing ring slot 33, or limiting groove 32 to seal the product. Moreover, by setting up lifting component 2, the worker does not need to be in contact with the water inside the water tank 10 for a long time, making the worker comfortable and safe. Since there are eight sets of fixtures 14, eight products can be loaded at one time, and each workstation tests the low-pressure water flow separately, which makes the product testing efficiency higher, so as to realize the highly practical function of the testing equipment. Thus, when using the testing equipment, the equipment fixtures can be quickly disassembled for products with different outer diameters, the program can be quickly called, and it is compatible with the testing of various models of drain valves. At the same time, the worker does not need to be in contact with water for a long time, making the worker comfortable and safe, and the testing efficiency is higher, thus completing the use of the testing equipment.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
