[0049] As described in the background technology, most tests are carried out by directly controlling the opening and closing of the pulse solenoid valve through a controller to detect the open and closed valve status of the pulse solenoid valve, and there are fewer devices for unified testing of other performances of the pulse solenoid valve or the testing methods are more cumbersome, which will affect the accuracy and efficiency of the test, and may also cause the application flushing valve to malfunction or operate incorrectly under certain operating conditions, affecting the quality of the application flushing valve.

[0050] Based on this, an embodiment of the present invention proposes a testing device and a testing method for a pulse solenoid valve to improve the comprehensiveness and accuracy of the pulse solenoid valve test.

[0051] like Figure 1 and Figure 3 As shown, a pulse solenoid valve testing device provided in some embodiments of the present invention includes: a first regulating module 100 , a second regulating module 200 , a third regulating module 300 , a control module 400 , a first power supply port 500 and a second power supply port 600 .

[0052] The first power supply port 500 is electrically connected to the first external power supply, and the first power supply port 500 is also electrically connected to the power supply end of the first regulating module 100 . The first external power supply outputs a driving voltage, which is supplied to the first regulating module 100 through the first power supply port 500 .

[0053] The first external power supply is a voltage-regulated DC power supply, and the voltage supplied by the first power supply port 500 is within the set working voltage range of the pulse solenoid valve being measured.

[0054] In one embodiment, the voltage supplied by the first power supply port 500 can be adjusted according to the working voltage of the pulse solenoid valve to be tested, and then supplied to the first adjustment module 100 to implement testing using multiple working voltages. That is, the voltage supplied by the first power supply port 500 is adjustable.

[0055] The second power supply port 600 is electrically connected to the second external power supply, and the second power supply port 600 is also electrically connected to the power supply end of the first regulating module 100 . The second external power supply outputs a driving voltage, which is supplied to the first regulating module 100 through the second power supply port 600 .

[0056] The second external power supply is a voltage-regulated DC power supply, and the voltage supplied by the second power supply port 600 is within the operating voltage range of the pulse solenoid valve being measured.

[0057] The input end of the first regulating module 100 is electrically connected to the control module 400, and the output end of the first regulating module 100 is electrically connected to the power supply end of the second regulating module 200. The first regulating module 100 can adjust the input voltage of the second regulating module 200 to realize power supply to the second regulating module 200 through the first external power supply or the second external power supply. In other words, through the regulation of the control module 400, the first regulating module 100 can adjust the on-off between the first power supply port 500, the second power supply port 600 and the second regulating module 200, thereby adjusting the voltage input to the second regulating module 200 to test the pulse solenoid valve with different voltage intensities.

[0058] The input end of the second regulating module 200 is electrically connected to the control module 400, and the output end of the second regulating module 200 is electrically connected to the pulse solenoid valve to be measured, and the second regulating module 200 can adjust the operating state of the pulse solenoid valve to be measured. That is to say, through the regulated input voltage and the regulation of the control module 400, the second regulating module 200 can control the opening and closing of the pulse solenoid valve to be measured, and adjust the opening time of the pulse solenoid valve to be measured, thereby realizing the adjustment of the operating state, so as to perform an opening and closing test and a flow test on the pulse solenoid valve.

[0059] The input end of the third regulating module 300 is electrically connected to the control module 400, and the output end of the third regulating module 300 is electrically connected to the pulse solenoid valve to be tested. The third regulating module 300 can supply water to the pipeline where the pulse solenoid valve to be tested is located, and adjust the water supply pressure of the pipeline. In other words, through the regulation of the control module 400, the third regulating module 300 can supply water to the pipeline where the pulse solenoid valve to be tested is located, and adjust the water supply pressure of the pipeline, so as to test the pulse solenoid valve with different water pressure strengths.

[0060] The control module 400 can regulate the first regulating module 100 to adjust the input voltage of the second regulating module 200. The control module 400 can also regulate the second regulating module 200 to adjust the operating state. The control module 400 can also regulate the third regulating module 300 to adjust the water supply pressure.

[0061] By setting the first power supply port 500, the second power supply port 600 and the first adjustment module 100, the input voltage is adjusted to test the pulse solenoid valve with different voltage strengths, and the control module 400 is used to regulate the power supply. Compared with the controller 410 in the prior art directly controlling the operation of the pulse solenoid valve, the test accuracy is higher; by setting the second adjustment module 200, the operation state of the pulse solenoid valve is adjusted to perform an opening and closing test and a flow test on the pulse solenoid valve; by setting the third adjustment module 300, the water supply pressure is adjusted to test the pulse solenoid valve with different water pressure strengths, thereby testing the full performance of the pulse solenoid valve, testing the voltage strength, water pressure strength and opening and closing performance, and improving the comprehensiveness, accuracy and test efficiency of the pulse solenoid valve test. Prevent the application flushing valve of the pulse solenoid valve from having a situation where the flushing response is not timely or remains in an open state when not needed, which affects the quality of the application flushing valve, so as to improve the performance of the application flushing valve and extend the service life of the application flushing valve.

[0062] like Figure 2 As shown, the pulse solenoid valve testing device provided in some embodiments of the present invention further includes: a detection module 700.

[0063] The detection module 700 is connected to the third regulating module 300 , and the output end of the detection module 700 is electrically connected to the control module 400 . The detection module 700 can detect the current flushing pressure and flushing flow of the pipeline where the pulse solenoid valve is located.

[0064] Among them, the flushing flow includes: instantaneous flushing volume and cumulative flushing volume.

[0065] That is to say, the detection module 700 and the pulse solenoid valve being tested are both arranged on the same pipeline. During the test of the pulse solenoid valve being tested, the detection module 700 detects the current flushing water pressure and flushing water flow in the pipeline, and sends them to the control module 400. The control module 400 obtains the current flushing water pressure and flushing water flow through the detection module 700, and detects whether the operating status of the pulse solenoid valve being tested is normal based on the current flushing water pressure and flushing water flow.

[0066] In one embodiment, the control module 400 detects whether the open valve state and the closed valve state of the measured pulse solenoid valve are normal according to the current flushing water pressure, so as to detect the operating state of the measured pulse solenoid valve; the control module 400 detects whether the open valve time of the measured pulse solenoid valve is normal according to the flushing water flow, so as to detect the operating state of the measured pulse solenoid valve.

[0067] like Figure 1 and Figure 2 As shown, the control module 400 provided in some embodiments of one aspect of the present invention includes: a controller 410 , a regulation unit 420 and a regulation port 430 .

[0068] The control port 430 is electrically connected to an external control power supply, and the control port 430 is also electrically connected to an input end of the control unit 420 . The external control power supply outputs a high-level voltage and a low-level voltage, which are supplied to the control unit 420 through the control port 430 .

[0069] Among them, Figure 1 and Figure 2 As shown, the control port 430 includes: a high level supply port and a low level supply port. The control unit 420 is connected to the external control power supply through the high level supply port.

The regulating unit 420 can control the on-off between the regulating port 430 and the second regulating module 200 .

[0072] That is to say, through the control of the controller 410, the control unit 420 can connect the control port 430 and the second regulation module 200 to output the high level voltage or the low level voltage to the second regulation module 200; or cut off the control port 430 and the second regulation module 200 to prevent the high level voltage or the low level voltage from being output to the second regulation module 200, thereby realizing the control of the second regulation module 200.

[0073] The controller 410 is electrically connected to the first regulating module 100 , the second regulating module 200 , the third regulating module 300 , the detection module 700 and the control unit 420 .

The controller 410 can also regulate the second regulating module 200 and the regulating unit 420 to adjust the operating state of the measured pulse solenoid valve. The controller 410 can also regulate the third regulating module 300 to adjust the water supply pressure of the pipeline where the measured pulse solenoid valve is located. The controller 410 can also detect the measured pulse solenoid valve according to the flushing flow rate and the current flushing pressure.

[0075] Among them, Figure 1 and Figure 2 As shown, the control unit 420 includes: an optical coupler isolator 421 , a third relay 422 and a fourth relay 423 .

[0076] The input end of the third relay 422 is electrically connected to the controller 410, the output end of the third relay 422 is electrically connected to the input end of the optocoupler isolator 421, the input end of the fourth relay 423 is electrically connected to the regulation port 430 and the controller 410 respectively, the output end of the fourth relay 423 is electrically connected to the optocoupler isolator 421, and the output end of the optocoupler isolator 421 is electrically connected to the input end of the second regulation module 200.

Among them, the valve closing signal is a high level voltage, and the driving signal is a 12V DC voltage.

[0078] like Figure 1 As shown, in another embodiment, the controller 410 drives the third relay 422, the third relay 422 conducts the controller 410 and the optocoupler isolator 421, the controller 410 outputs a driving signal to the optocoupler isolator 421, the light emitting diode of the optocoupler isolator 421 is turned on, the controller 410 sends a second control signal to the fourth relay 423, the fourth relay 423 conducts the control port 430 and the optocoupler isolator 421, so that the low-level voltage output by the external control power supply can be sent to the second regulating module 200, so as to realize the control module 400 outputs a valve opening signal.

[0079] By setting up a first adjustment module 100, two power supply ports, a control port 430, a controller 410 and a control unit 420, the power supply is indirectly controlled by using the controller 410 and the control unit 420. Compared with the prior art in which the controller 410 directly controls the operation of the pulse solenoid valve, the test accuracy of this solution is higher.

[0080] like Figure 1 and Figure 2 As shown, the third regulating module 300 provided in some embodiments of one aspect of the present invention includes: a water supply pipeline 310 , a pressure water pump 320 , a pneumatic ball valve 330 and a pressure converter 340 .

The pressure supply frequency converter 340 can adjust the pressure supply water pump 320 , thereby adjusting the water supply pressure.

[0083] That is to say, through the regulation of the controller 410, the pressure supply inverter 340 can adjust the operating frequency of the pressure supply water pump 320, thereby adjusting the water pressure of the pipeline water in the water supply pipeline 310, so as to realize the testing of the pulse solenoid valve under test with different water pressure intensities, thereby facilitating the determination of the water pressure bearing capacity of the pulse solenoid valve, improving the performance and service life of the applied flushing valve, and thus improving the user experience.

[0162] The embodiment provided in the present application adjusts the operating state of the pulse solenoid valve by regulating the second regulating module to perform an opening and closing test on the pulse solenoid valve. The opening and closing test is performed under test conditions with different water pressures to improve the comprehensiveness, accuracy and test efficiency of the pulse solenoid valve test, facilitate determining the opening and closing state performance of the pulse solenoid valve, improve the performance of the applied flushing valve, and thus improve the user experience.

[0163] In S230 of some embodiments, after closing the measured pulse solenoid valve and starting water supply through S210 and S220, the detection module detects the current flushing water pressure of the flushing water pipeline where the measured pulse solenoid valve is located, and feeds back the current flushing water pressure to the control module. The control module obtains the current flushing water pressure, and determines whether the closed valve state of the measured pulse solenoid valve is normal through the current flushing water pressure.

[0164] The control module may determine that the closed valve state of the pulse solenoid valve under test is normal by the current flushing pressure being greater than a set threshold value, or may determine that the closed valve state is normal by other means, which is not limited in the present embodiment.

[0166] In S240 of some embodiments, if the closed valve state of the measured pulse solenoid valve is normal, the control module sends a valve opening signal to the second regulating module, and the second regulating module controls the measured pulse solenoid valve to open through the valve opening signal.

[0167] In one embodiment, when the voltage supplied by the first power supply port is adjusted to the input voltage, the controller drives the third relay, the third relay turns on the controller and the optocoupler isolator, the controller outputs a drive signal to the optocoupler isolator, the light emitting diode of the optocoupler isolator is turned on, the controller sends a second control signal to the fourth relay, the fourth relay turns on the regulation port and the optocoupler isolator, and the regulation port supplies a low-level voltage.

And from S210 to S240, it can be seen that the present application saves energy by closing the valve first, then starting the water supply, and finally opening the valve, which helps to prevent the risk of excessive pressure during the startup process of the device, reduce the energy loss caused by the startup shock, and thus improve the overall efficiency of the device.

[0171] In S250 of some embodiments, after the measured pulse solenoid valve is opened and water supply starts through S220 and S240, the detection module detects the current flushing water pressure of the flushing water pipeline where the measured pulse solenoid valve is located, and feeds back the current flushing water pressure to the control module. The control module obtains the current flushing water pressure, and determines whether the valve opening state of the measured pulse solenoid valve is normal through the current flushing water pressure.

[0172] When the closed valve state of the measured pulse solenoid valve is normal and the open valve state of the measured pulse solenoid valve is also normal, it can be determined that both the open valve state and the closed valve state of the measured pulse solenoid valve are normal, thereby operating S300 to switch the water pressure intensity.

[0173] The control module may determine that the valve opening state of the pulse solenoid valve under test is normal by the current flushing pressure being less than a set threshold value, or may determine that the valve opening state is normal by other means, which is not limited in the present embodiment.

[0184] Among them, the first valve opening time length and the second valve opening time length can be two seconds, four seconds or other time lengths, and can also be set according to actual needs. There is no specific limitation on them in this embodiment.

[0185] In S600 of some embodiments, when the control module adjusts the first flow control plate, the detection module detects the flushing flow and outputs it to the control module. The control module obtains the flushing flow and detects whether the set first valve opening time maintained by the measured pulse solenoid valve is normal based on the instantaneous flushing volume in the flushing flow.

[0186] When the controller adjusts the second flow control board, the detection module detects the flushing flow and outputs it to the control module. The control module obtains the flushing flow and detects whether the set second valve opening time maintained by the measured pulse solenoid valve is normal based on the accumulated flushing volume in the flushing flow.

[0187] If the two valve opening times of the tested pulse solenoid valve are normal, the flow test is considered to be qualified.

[0188] Among them, by accumulating the flushing volume and the instantaneous flushing volume to detect whether the valve opening time of the measured pulse solenoid valve is normal, the pulse signal output by the flow control board, the obtained flushing volume and the set valve opening time can be combined through the data fusion algorithm to detect whether the valve opening time of the measured pulse solenoid valve is normal. The detection can also be achieved by other methods, and the detection method is not specifically limited in this application.

[0189] The embodiment provided by the present application uses a control module and a second regulating module to perform flow testing on the pulse solenoid valve. The instantaneous flushing volume is used to detect the response time and flow control accuracy of the measured pulse solenoid valve within the first valve opening time. The cumulative flushing volume is used to ensure the consistency of the performance of the measured pulse solenoid valve, and the response time and flow control accuracy of the measured pulse solenoid valve can also be detected. This allows the full performance of the pulse solenoid valve to be tested, improves the comprehensiveness, accuracy and test efficiency of the pulse solenoid valve test, facilitates the determination of the response speed of the pulse solenoid valve, improves the response efficiency and service life of the applied flushing valve, and thus improves the user experience.

[0190] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
