The valve provided on the first connecting pipe 63 is valve nine 631, and the valve provided on the second connecting pipe 64 is valve ten 641. Since the electronic water valve 4 has two liquid outlets, to enable simultaneous flow and leakage testing of both outlets, both outlets are connected to pipes during installation. Liquid outlet 1 42 and liquid outlet 2 43 are connected in parallel. When testing liquid outlet 1 42, the valve on the second connecting pipe 64 connected to liquid outlet 2 43 is closed. When testing liquid outlet 2 43, the valve on the first connecting pipe 63 connected to liquid outlet 1 42 is closed, thereby improving testing efficiency.

[0039] Furthermore, the system includes an electrical cabinet 7 and an external computer 71. The external computer 71 is connected to a display screen that displays test data and results. The electronic water valve 4 is provided with a power connection port, and a power connection cable is provided within the electrical cabinet 7. When power is on, the valve disc within the electronic water valve 4 moves downward, opening the first liquid outlet 42. When power is off, the internal valve disc moves upward, opening the second liquid outlet 43. Different liquid outlets are opened in different states. The various pressure sensors and flow sensors transmit test results back to the computer, which compares them with set values ​​to determine whether the water valve passes the test.

[0040] In some embodiments, the fixture 1 is provided with a fixing plate 11, which is provided with fixing holes for fixing. The fixture 1 is fixed by screws, etc. The fixed position can be a workbench or a rack. A fixing cavity 12 is provided on the upper surface of the fixing plate 11. The bottom of the fixing cavity 12 is an arc that matches the outer surface of the electronic water valve 4 to be tested. The arc area is small to accommodate electronic water valves 4 of different sizes. A bypass groove for avoiding the inlet and outlet of the electronic water valve 4 is provided on the side of the fixing cavity 12. The depth of the bypass groove is large and is suitable for electronic water valves 4 of different models. A clamping block 13 is provided on the upper side of the fixing cavity 12.

[0041] Furthermore, a guide plate 15 is provided on the upper side of the clamping block 13, and the clamping block 13 and the guide plate 15 are connected by a guide shaft 16. There are two guide shafts 16 arranged side by side, and a spring is provided on the guide shaft 16. The guide shaft 16 slides in the guide plate 15. One end of the guide shaft 16 is fixedly connected to the clamping block 13. A through hole is provided in the guide plate 15. The guide shaft 16 passes through the guide plate 15 and slides in the guide plate 15. A stopper is provided at its protruding end. The stopper limits the position of the guide shaft 16 to prevent the guide shaft 16 from falling off. The setting of the spring and the guide shaft 16 makes the clamping block 13 have a certain elasticity to prevent the electronic water valve 4 from being damaged by excessive clamping force. At the same time, it can also be suitable for different models of electronic water valves 4.

[0042] In some embodiments, a second valve 65 is provided on the liquid outlet pipe 6 , and the second valve 65 is connected in parallel with the leakage detection sensor 61 .

[0043] When detecting the flow of the corresponding outlet, open valve 2 65. At this time, the water in the return pipe flows back through the opened valve 2 65. The flow sensor 51 detects the flow rate and detects whether the flow is smooth when the valve is opened. This is used to determine whether the electronic water valve 4 is qualified.

[0044] When detecting the leakage amount of the corresponding outlet, close valve 2 65. At this time, the water in the return pipe flows back through the leakage detection sensor 61. The amount of water passing through the leakage detection sensor 61 is the leakage amount of the electronic water valve 4, which is used to judge whether the electronic water valve 4 is qualified. The leakage detection sensor 61 is also a flow sensor, which can detect the flow rate of the liquid.

[0045] Furthermore, a water pump 31 and a valve 32 are provided on the main pipeline 3, the water outlet of the water supply tank 2 is connected to the main pipeline 3, a liquid level sensor is provided in the water supply tank 2, and a water supply pipe is connected to the upper side of the water supply tank 2. When the water level in the water supply tank 2 drops to a certain position, water is automatically supplied, and the water pump 31 drives the water in the main pipeline 3 to flow to the water inlet pipe, and the water flows back from the water outlet pipe.

[0046] In some embodiments, the liquid inlet pipe 5 is provided with a valve 54, and the liquid outlet pipe 6 is provided with a valve 68. The provision of the valve 54 and the valve 68 plays a role in controlling the on-off function of the liquid outlet pipe 6 and the liquid inlet pipe 5.

[0047] Furthermore, an exhaust assembly is provided on the liquid inlet pipe 5 and the liquid outlet pipe 6, and the exhaust assembly includes an outlet pipe 1 55 connected to the liquid inlet pipe 5 and an outlet pipe 2 66 connected to the liquid outlet pipe 6. A valve 7 53 is provided on the outlet pipe 1 55, and a valve 8 67 is provided on the outlet pipe 2 66. The outlet pipe 1 55 and the outlet pipe 2 66 are both vertically arranged with openings at the upper ends. After the water in the water tank enters the pipeline, the valve 7 53 and the valve 8 67 are opened. Since the outlet pipe 1 55 and the outlet pipe 2 66 are vertically arranged, the water will enter the air inlet pipe at this time, and then enter the air outlet pipe through the electronic water valve 4 to be tested. Since the valve 7 53 and the valve 8 67 are opened, the air is discharged from the valve 7 53 and the valve 8 67, and due to the atmospheric pressure, the water in the outlet pipe 1 55 and the outlet pipe 2 66 will not flow out. After the air is discharged, the valve 7 53 and the valve 8 67 are closed to reduce the influence of the gas on the test results.

[0048] In some embodiments, the liquid inlet pipe 5 and the liquid outlet pipe 6 are both connected to a hose, and quick connectors are provided at both ends of the hose to connect to the liquid inlet 41 and two liquid outlets of the electronic water valve 4. The quick connectors are clamp-type quick connectors that can be tightened and can be used for liquid inlets and outlets of various diameters. After connection, they have good air tightness.

[0049] During the testing process, first place the electronic water valve 4 to be tested into the fixed cavity 12, press the pressing block 13 downward, connect the liquid inlet 41 of the electronic water valve 4 to the liquid inlet pipe 5, and connect the liquid outlet 1 42 and liquid outlet 2 43 to the liquid outlet pipe 6. After the connection is completed, start the test;

[0050] Before the test, all valves are in the closed state. The liquid outlet 42 is tested first. Therefore, the valve 9 631 on the connecting pipe 1 63 is opened first, and the valve connected to the water tank is opened. The water in the water tank enters the main pipe 3, the switch of the electrical cabinet 7 is turned on, and then the water pump 31 is turned on. The water in the main pipe 3 flows into the liquid inlet pipe 5. At this time, the liquid outlet 1 42 is in the open state. The valve 65 is opened, and the water flows back from the liquid outlet pipe 6. Then the valve 7 53 and the valve 8 67 are opened to exhaust. After exhausting, the valve 8 67 and the valve 7 53 are closed. The flow sensor 51 and the inlet pressure sensor 52 and the outlet pressure sensor 62 detect the values, detect the pressure and flow of the water passing through, and after comparison by the computer, it can be known whether the valve passability is qualified; then the electronic water valve 2 is powered off, and the liquid outlet 1 42 is closed after the power is cut off. Then the valve 65 is closed. At this time, the flow rate detected by the leakage detection sensor 61 is the leakage rate of the liquid outlet 1 42. The computer can compare it with the set range to know whether it is qualified. The process for testing liquid outlet 2 43 is the same as that for testing liquid outlet 1 42. Simply close valve 9 631 on connecting pipe 1 63 and open valve 10 641 on connecting pipe 2 64. The valves used in the entire device include automatically controlled solenoid valves, ball valves, and stop valves, enabling automatic testing, a simple structure, and reduced testing time.
