[0034] Reference Figure 5 As shown, the structures of the water tank system 1 2 and the water tank system 2 3 are the same. The water tank system 1 2 and the water tank system 2 3 both include a water pump 20, a pressure-stabilizing tank 21, a water tank 22, a safety valve 23, a water supply electronic valve 24, a heating pipe 25, a drain valve 26, a water tank bracket 27 and a filter 28. The water pump 20 and the water tank bracket 27 are both fixedly arranged on the test bench 1. The water tank 22 is installed on the water tank bracket 27. The pressure-stabilizing tank 21 is arranged on the water pump 20. The water pump 20 is connected to the water tank 22, and a filter 28 is provided in the pipeline between the water pump 20 and the water tank 22. The safety valve 23 and the water supply electronic valve 24 are arranged on the top plate of the water tank 22. The heating pipe 25 is arranged on the side wall of the water tank 22, and the heating pipe 25 is used to heat the medium in the water tank 22. The drain valve 26 is arranged on the bottom plate of the water tank 22, and the drain valve 26 is used to discharge impurities in the water tank 22. The water outlet box 22 is provided with a liquid level sensor 32. The water outlet box 22 is provided with a temperature sensor 33.

[0035] A drain valve 26 is provided at the bottom of the water tank 22. When the water circulates too many times, the drain valve 26 at the bottom can be opened to drain all the water in the water tank 22. The test system can be set to a constant pressure mode or a constant flow mode. By controlling the operating power of the pump, different flow rates can be achieved through the solenoid valve at the same pressure, or the same flow rate can flow through the solenoid valve at different pressures, so as to achieve the performance test of the solenoid valve to be tested with water as the medium. In this process, various performance parameters of the solenoid valve are recorded and displayed on the touch screen. The data will also be stored in time for subsequent viewing and export. A water leakage detection sensor is installed on the table to monitor whether there is leakage in the solenoid valve to be tested for a period of time under the set pressure.

[0036] The water tank 22 is equipped with a liquid level sensor 32, a temperature sensor 33, a heating pipe 25, a sewage outlet, a water outlet, a water inlet, and a negative pressure explosion-proof integrated valve. The water outlet is connected to a filter 28 for filtering impurities in the water, and the water inlet is connected to an electromagnetic on-off valve. Whether the water tank 22 needs to be replenished with water is determined based on the signal fed back by the liquid level sensor 32. The water pump 20 is used to pump water out of the water tank 22 and pump it into the corresponding pipeline system. The pressure regulating tank 21 is used to stabilize the internal pressure of the system.

[0037] The multi-media solenoid valve testing device of the present invention has three testing modes:

[0038] (1) Normal temperature water test mode: External tap water or liquid prepared by the customer can flow into the water tank 22 when the water supply electronic valve 24 is opened, and then the water in the water tank 22 is pumped into the test pipeline by the water pump 20, flows through the flow sensor 29, the pressure reducing valve 30, the pressure sensor 31, the flow regulating valve 11, the manual stop valve 2 10, the test solenoid valve, the manual stop valve 1 9, and finally flows back to the water tank 22. During the test, close the manual stop valve 1 9 to perform the pressure holding test.

[0039] (2) High temperature water test mode: the test temperature (between 0-95°C) is set on the touch screen, heated by the heating tube 25, and the temperature sensor 33 provides feedback. When the customer's set value is reached, the water pump 20 will start working, pumping water into the test pipeline, flowing through the flow sensor 29, the pressure reducing valve 30, the pressure sensor 31, the flow regulating valve 11, the manual stop valve 2 10, the test solenoid valve, the manual stop valve 1 9, and finally flowing back to the water tank 22. During the test, close the manual stop valve 1 9 to perform the pressure holding test.

[0040] (3) The steam test mode is: start the steam generator 4, the steam flows through the steam inlet pipe 39, the flow sensor 29, the pressure reducing valve 30, the pressure sensor 31, the flow regulating valve 11, the manual stop valve 10, the test solenoid valve, the manual stop valve 9, and finally enters the exhaust pipe 38 to connect to the customer's on-site sewage system.

[0041] When the electronic on-off valve 1 5 is opened, the electronic on-off valve 2 6, the electronic on-off valve 3 7 and the electronic on-off valve 4 8 are closed, the test mode is a 3-station normal temperature water test, a 3-station high temperature water test, and a 2-station steam test. When the electronic on-off valve 2 6 and the electronic on-off valve 4 8 are opened, the electronic on-off valve 1 5 and the electronic on-off valve 3 7 are closed, the steam test pipeline is borrowed by the high temperature water test, and the test mode is a 3-station normal temperature water test and a 5-station high temperature water test. Since both water pump systems are equipped with a heating pipe 25, an 8-station high temperature water test or an 8-station normal temperature water test, or simultaneous testing of two high temperature waters of different temperatures, etc. can also be achieved. The return water pipelines of the two water tanks 22 are independent of each other to avoid heat exchange between waters of different temperatures.

[0042] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
