[0008] A fourth aspect of the present invention provides a readable storage medium.

[0009] In view of this, a first aspect of the present invention provides a detection device for a thermostatic valve. The thermostatic valve includes multiple water inlets and water outlets. The detection device includes a water inlet assembly, an inlet water temperature detection assembly, a water outlet assembly, and a first outlet water temperature detection component.

The water outlet assembly is connectable to the water outlet. The first outlet water temperature detection component is disposed on the water outlet assembly. A first control module is electrically connected to the inlet water temperature detection assembly and the first outlet water temperature detection component, respectively.

[0010] The detection device for a thermostatic valve provided by the present invention includes a water inlet assembly, a water inlet temperature detection assembly, a water outlet assembly, and a first water outlet temperature detection component. When the thermostatic valve needs to be tested, the water inlet end of the thermostatic valve is connected to the water inlet assembly, and the water outlet end of the thermostatic valve is connected to the water outlet assembly, so that the detection device of the thermostatic valve can supply water to the thermostatic valve through the water inlet assembly, and the water flows out from the water outlet assembly after passing through the thermostatic valve, thereby forming a water path for testing the thermostatic valve. A water inlet temperature detection assembly is provided on the water inlet assembly of the detection device, and the water inlet temperature detection assembly can detect the temperature of water flowing through the water inlet assembly. A first water outlet temperature detection component is provided on the water outlet assembly of the detection device, and the first water outlet temperature detection component can detect the temperature of water flowing through the water outlet assembly. When the detection device detects the thermostatic valve, the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component can be sent to the first control module. The first control module can determine the position of the valve core of the thermostatic valve based on the temperature difference between the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component, and then determine whether the valve core of the thermostatic valve can move to a preset position under the drive of the driving component, so as to determine whether the driving component and the valve core can work normally, thereby realizing automatic detection of the thermostatic valve, improving the automation level of the thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0011] In one technical solution of the present invention, the thermostatic valve further includes a second outlet water temperature detection component, which is disposed on the water outlet end and can be electrically connected to the first control module.

[0012] In this technical solution, a second water outlet temperature detection component is provided on the water outlet of the thermostatic valve, and the detection device can also detect whether the second water outlet temperature detection component can work normally during use and whether the installation position is accurate. When it is necessary to detect whether the second water outlet temperature detection component can work normally during use and whether the installation position is accurate, the second water outlet temperature detection component can be connected to the first control module, and then the second water outlet temperature detection component can send the detected temperature to the first control module, so that the first control module can judge whether the second water outlet temperature detection component can work normally during use and whether the installation position is accurate based on the temperature detected by the second water outlet temperature detection component, thereby realizing automatic detection of the second water outlet temperature detection component, improving the degree of automation of the thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0013] In one technical solution of the present invention, the thermostatic valve also includes a valve core, and the multiple water inlet ends also include a first water inlet end; the water inlet assembly also includes a first water inlet pipe, which can be connected to the first water inlet end; the water inlet temperature detection assembly includes a first water inlet temperature detection component, and the first water inlet temperature detection component is arranged on the first water inlet pipe.

[0014] In this technical solution, a valve core is provided on the thermostatic valve, which can control the opening of the cold water end and the hot water end of the thermostatic valve, thereby adjusting the water temperature. The water inlet assembly includes a first water inlet pipe, which can provide hot water to the first water inlet end of the thermostatic valve. The water inlet temperature detection assembly includes a first water inlet temperature detection component, which can detect the temperature of the hot water flowing through the first water inlet pipe.

[0015] When the valve core and the driving component are tested, the first water inlet pipeline is controlled to deliver hot water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to the position where the hot water is fully open and the cold water is fully closed, that is, the first position. The first control module controls the first water inlet temperature detection component to detect the temperature of the hot water flowing through the first water inlet pipeline, and uses it as the first water inlet temperature. The first control module controls the first water outlet temperature detection component to detect the temperature of the hot water flowing through the water outlet component, and uses it as the first water outlet temperature. The first control module respectively obtains the temperature detected by the first water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component. The measured temperature is compared with the temperature detected by the first water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component. When the difference between the temperature detected by the first water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component is less than or equal to 1 degree Celsius, it indicates that the valve core is in the zero position, that is, the valve core is in the position where the hot water is fully open and the cold water is fully closed. It can then be detected that the driving component can accurately drive the valve core to rotate to the zero position, thereby realizing automatic detection of the valve core and the driving component, improving the automation level of the thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0016] In one technical solution of the present invention, the multiple water inlet ends also include a second water inlet end; the water inlet assembly also includes a second water inlet pipe, which can be connected to the second water inlet end; the water inlet temperature detection assembly also includes a second water inlet temperature detection component, which is arranged on the second water inlet pipe.

[0017] In this technical solution, the water inlet assembly also includes a second water inlet pipe, which can provide cold water to the second water inlet end of the thermostatic valve. The water inlet temperature detection assembly includes a second water inlet temperature detection component, which can detect the temperature of the cold water flowing through the second water inlet pipe.

[0018] When the valve core and the driving component are tested, the second water inlet pipeline is controlled to deliver cold water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to the position where the hot water is fully closed and the cold water is fully opened, that is, the second position. The first control module controls the second water inlet temperature detection component to detect the temperature of the cold water flowing through the first water inlet pipeline, and uses it as the second water inlet temperature. The first control module controls the first water outlet temperature detection component to detect the temperature of the cold water flowing through the water outlet component, and uses it as the first water outlet temperature. The first control module respectively obtains the temperature detected by the second water inlet temperature detection component and the first water outlet temperature detection component. The temperature detected by the second water inlet temperature detection component is compared with the temperature detected by the first water outlet temperature detection component. When the difference between the temperature detected by the second water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component is less than or equal to 1 degree Celsius, it indicates that the valve core is in the position where the cold water is fully open and the hot water is fully closed. It can then be detected that the driving component can accurately drive the valve core to rotate to the second position, realizing automatic detection of the valve core and driving component, improving the automation level of thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and has higher detection reliability, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0019] In one technical solution of the present invention, the thermostatic valve further includes a third water inlet temperature detection component, which is disposed on the second water inlet end and is electrically connected to the first control module.

[0020] In this technical solution, a third water inlet temperature detection component is provided on the thermostatic valve, and the detection device can also detect whether the third water inlet temperature detection component can work normally during use and is accurately installed. When it is necessary to detect whether the third water inlet temperature detection component can work normally during use and is accurately installed, the third water inlet temperature detection component can be connected to the first control module, and then the third water inlet temperature detection component can send the detected temperature to the first control module, so that the first control module can judge whether the third water inlet temperature detection component can work normally during use and is accurately installed based on the temperature detected by the third water inlet temperature detection component, thereby realizing automatic detection of the third water inlet temperature detection component, improving the degree of automation of thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0021] In one technical solution of the present invention, the thermostatic valve also includes a first flow detection component, which is arranged at the second water inlet end and electrically connected to the first control module; the detection device also includes a second flow detection component, which is arranged on the second water inlet pipeline and electrically connected to the first control module.

[0022] In this technical solution, a first flow detection component is further provided at the second water inlet end of the thermostatic valve. When the first flow detection component needs to be tested, the first flow detection component can be connected to the first control module, and then the first flow detection component is tested according to the second flow detection component provided on the second water inlet pipe. This enables automatic detection of the first flow detection component, improves the automation level of thermostatic valve testing, and thus increases the speed of thermostatic valve testing. It also avoids the influence of human factors on the test results, improves the reliability of the test, and improves the accuracy of thermostatic valve testing, thereby improving the quality of the thermostatic valve.

[0023] When detecting the first flow detection component, the second water inlet pipe is controlled to supply cold water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to a position where the hot water is fully closed and the cold water is fully opened. After a delay of a first preset time, the first control module controls the first flow detection component to detect the flow of cold water flowing through the second water inlet end and uses it as the first flow rate. The first control module controls the second flow detection component to detect the flow of cold water flowing through the second water inlet pipe and uses it as the second flow rate. The first control module respectively obtains the flow rate detected by the first flow detection component and the flow rate detected by the second flow detection component, and compares the flow rate detected by the first flow detection component with the flow rate detected by the second flow detection component. If the flow rate detected by the first flow detection component and the flow rate detected by the second flow detection component are within a 10% error range, then the first flow detection component can operate normally during use and is accurately installed, that is, the first flow detection component can accurately detect the flow rate of cold water flowing through the second water inlet end.

[0024] In one technical solution of the present invention, the thermostatic valve also includes a driving component, which is connected to the valve core; the detection device also includes a second control module, which can be electrically connected to the driving component to send a preset number of pulses to the driving component to control the driving component.

The detection device is provided with a second control module, which can control the operation of the driving component, so that the detection device drives the valve core to move to the specified position according to the test requirements, further improving the degree of automation of the thermostatic valve detection.

[0026] In one technical solution of the present invention, the detection device of the thermostatic valve also includes a water inlet solenoid valve and a water outlet solenoid valve; the water inlet solenoid valve is arranged on the water inlet assembly; and the water outlet solenoid valve is arranged on the water outlet assembly.

[0027] In this technical solution, by setting a water inlet solenoid valve and a water outlet solenoid valve, the water inlet component and the water outlet component are controlled, and the degree of automation of the thermostatic valve detection is further improved.

[0028] In a technical solution of the present invention, the detection device of the thermostatic valve further includes a display module and a communication module; the display module is electrically connected to the first control module; and the communication module is connected to the first control module.

[0029] In this technical solution, the thermostatic valve detection device also includes a display module electrically connected to the first control module to display the test results of the thermostatic valve and the status of each detection component, thereby making it more convenient for operators to test the thermostatic valve. The thermostatic valve detection device also includes a communication module connected to the first control module to upload the test results to a server for storage and subsequent tracing of the test results of the thermostatic valve.

[0030] The second aspect of the present invention provides a method for detecting a thermostatic valve, comprising: controlling an inlet water temperature detection component to detect the inlet water temperature of the inlet water component; controlling a first outlet water temperature detection component to detect the first outlet water temperature of the outlet water component; and detecting the position of the valve core of the thermostatic valve according to the inlet water temperature and the first outlet water temperature.

[0031] The present invention provides a method for testing a thermostatic valve. When the thermostatic valve needs to be tested, the water inlet of the thermostatic valve is connected to the water inlet assembly, and the water outlet of the thermostatic valve is connected to the water outlet assembly. This allows the thermostatic valve detection device to supply water to the thermostatic valve through the water inlet assembly. After passing through the thermostatic valve, the water flows out of the water outlet assembly, thereby forming a water path for testing the thermostatic valve. The water inlet assembly of the detection device is provided with an inlet water temperature detection component, which can detect the temperature of water flowing through the water inlet assembly. The water outlet assembly of the detection device is provided with a first outlet water temperature detection component, which can detect the temperature of water flowing through the outlet assembly. When the detection device detects the thermostatic valve, the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component can be sent to the first control module. The first control module can determine the position of the valve core of the thermostatic valve based on the temperature difference between the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component, and then determine whether the valve core of the thermostatic valve can move to a preset position under the drive of the driving component, so as to determine whether the driving component and the valve core can work normally, thereby realizing automatic detection of the thermostatic valve, improving the automation level of the thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0032] In addition, the thermostatic valve detection method in the above technical solution provided by the present invention may also have the following additional technical features:

[0033] In one technical solution of the present invention, the detection method of the thermostatic valve also includes: obtaining a second outlet water temperature from a second outlet water temperature detection component; and detecting whether the second outlet water temperature detection component is working normally based on the first outlet water temperature and the second outlet water temperature.

[0034] In this technical solution, a second water outlet temperature detection component is provided on the water outlet of the thermostatic valve, and the detection device can also detect whether the second water outlet temperature detection component can work normally during use and whether the installation position is accurate. When it is necessary to detect whether the second water outlet temperature detection component can work normally during use and whether the installation position is accurate, the second water outlet temperature detection component can be connected to the first control module, and then the second water outlet temperature detection component can send the detected temperature to the first control module, so that the first control module can judge whether the second water outlet temperature detection component can work normally during use and whether the installation position is accurate based on the temperature detected by the second water outlet temperature detection component, thereby realizing automatic detection of the second water outlet temperature detection component, improving the degree of automation of the thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0035] In one technical solution of the present invention, the inlet water temperature includes a first inlet water temperature, and detecting the position of the valve core of the thermostatic valve according to the inlet water temperature and the first outlet water temperature includes: detecting whether the valve core of the thermostatic valve is in the first position according to the first inlet water temperature and the first outlet water temperature.

[0036] In this technical solution, a valve core is provided on the thermostatic valve, which can control the opening of the cold water end and the hot water end of the thermostatic valve, thereby adjusting the water temperature. The water inlet assembly includes a first water inlet pipe, which can provide hot water to the first water inlet end of the thermostatic valve. The water inlet temperature detection assembly includes a first water inlet temperature detection component, which can detect the temperature of the hot water flowing through the first water inlet pipe.

[0037] When the valve core and the driving component are tested, the first water inlet pipeline is controlled to deliver hot water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to the position where the hot water is fully open and the cold water is fully closed, that is, the first position. The first control module controls the first water inlet temperature detection component to detect the temperature of the hot water flowing through the first water inlet pipeline, and uses it as the first water inlet temperature. The first control module controls the first water outlet temperature detection component to detect the temperature of the hot water flowing through the water outlet component, and uses it as the first water outlet temperature. The first control module respectively obtains the temperature detected by the first water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component. The measured temperature is compared with the temperature detected by the first water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component. When the difference between the temperature detected by the first water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component is less than or equal to 1 degree Celsius, it indicates that the valve core is in the zero position, that is, the valve core is in the position where the hot water is fully open and the cold water is fully closed. It can then be detected that the driving component can accurately drive the valve core to rotate to the zero position, thereby realizing automatic detection of the valve core and the driving component, improving the automation level of the thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0038] In one technical solution of the present invention, the inlet water temperature includes a second inlet water temperature, and detecting the position of the valve core of the thermostatic valve according to the inlet water temperature and the first outlet water temperature includes: detecting whether the valve core of the thermostatic valve is in the second position according to the second inlet water temperature and the first outlet water temperature.

[0039] In this technical solution, the water inlet assembly also includes a second water inlet pipe, which can provide cold water to the second water inlet end of the thermostatic valve. The water inlet temperature detection assembly includes a second water inlet temperature detection component, which can detect the temperature of the cold water flowing through the second water inlet pipe.

[0040] When the valve core and the driving component are tested, the second water inlet pipeline is controlled to deliver cold water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to the position where the hot water is fully closed and the cold water is fully opened, that is, the second position. The first control module controls the second water inlet temperature detection component to detect the temperature of the cold water flowing through the first water inlet pipeline, and uses it as the second water inlet temperature. The first control module controls the first water outlet temperature detection component to detect the temperature of the cold water flowing through the water outlet component, and uses it as the first water outlet temperature. The first control module respectively obtains the temperature detected by the second water inlet temperature detection component and the first water outlet temperature detection component. The temperature detected by the second water inlet temperature detection component is compared with the temperature detected by the first water outlet temperature detection component. When the difference between the temperature detected by the second water inlet temperature detection component and the temperature detected by the first water outlet temperature detection component is less than or equal to 1 degree Celsius, it indicates that the valve core is in the position where the cold water is fully open and the hot water is fully closed. It can then be detected that the driving component can accurately drive the valve core to rotate to the second position, realizing automatic detection of the valve core and driving component, improving the automation level of thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and has higher detection reliability, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0041] In one technical solution of the present invention, the detection method of the thermostatic valve also includes: obtaining a third water inlet temperature from a third water inlet temperature detection component; detecting whether the third water inlet temperature detection component is working normally based on the second water inlet temperature and the third water inlet temperature; or detecting whether the valve core of the thermostatic valve is in the second position based on the second water inlet temperature, the third water inlet temperature, the first water outlet temperature and the second water outlet temperature.

[0042] In this technical solution, a third water inlet temperature detection component is installed on the thermostatic valve. The detection device can also verify that the third water inlet temperature detection component is functioning properly and is accurately installed. This enables automatic detection of the third water inlet temperature detection component, improving the automation level of thermostatic valve testing and, in turn, increasing the speed of thermostatic valve testing. This also eliminates the influence of human factors on the test results, resulting in higher detection reliability, improved thermostatic valve detection accuracy, and ultimately, improved thermostatic valve quality.

[0043] In one technical solution of the present invention, a driving component is controlled to drive the valve core to rotate to a second position; after a first preset delay time, a first flow detected by the first flow detection component is obtained; the second flow detection component is controlled to detect a second flow in the second water inlet pipe; and based on the first flow and the second flow, whether the first flow detection component is working normally is detected.

[0044] In this technical solution, a first flow detection component is further provided at the second water inlet end of the thermostatic valve. When the first flow detection component needs to be tested, the first flow detection component can be connected to the first control module, and then the first flow detection component is tested according to the second flow detection component provided on the second water inlet pipe. This enables automatic detection of the first flow detection component, improves the automation level of thermostatic valve testing, and thus increases the speed of thermostatic valve testing. It also avoids the influence of human factors on the test results, improves the reliability of the test, and improves the accuracy of thermostatic valve testing, thereby improving the quality of the thermostatic valve.

[0045] When detecting the first flow detection component, the second water inlet pipe is controlled to supply cold water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to a position where the hot water is fully closed and the cold water is fully opened. After a delay of a first preset time, the first control module controls the first flow detection component to detect the flow of cold water flowing through the second water inlet end and uses it as the first flow rate. The first control module controls the second flow detection component to detect the flow of cold water flowing through the second water inlet pipe and uses it as the second flow rate. The first control module respectively obtains the flow rate detected by the first flow detection component and the flow rate detected by the second flow detection component, and compares the flow rate detected by the first flow detection component with the flow rate detected by the second flow detection component. If the flow rate detected by the first flow detection component and the flow rate detected by the second flow detection component are within a 10% error range, then the first flow detection component can operate normally during use and is accurately installed, that is, the first flow detection component can accurately detect the flow rate of cold water flowing through the second water inlet end.

[0046] In one technical solution of the present invention, before controlling the water inlet temperature detection component to detect the water inlet temperature of the water inlet component, the detection method also includes: controlling the second control module to send a preset number of pulses to the driving component to control the driving component to drive the valve core to rotate; after detecting the position of the valve core of the thermostatic valve according to the water inlet temperature and the first water outlet temperature, the detection method also includes: judging whether the driving component has lost steps according to the position of the valve core.

[0047] In this technical solution, the first control module transmits the maximum rotation angle of the thermostatic valve spool to the second control module. The second control module drives the stepper motor to rotate based on the final pulse number obtained by multiplying the maximum rotation angle by the pulse coefficient required per degree of the thermostatic valve stepper motor. The specific pulse number is sent to control the stepper motor's rotation. The temperature sensor determines whether it has lost steps, thereby achieving automatic detection of the drive components, improving the automation level of thermostatic valve detection, and thus increasing the speed of thermostatic valve detection. It also avoids the influence of human factors on the detection results, improves the reliability of the detection, and improves the accuracy of thermostatic valve detection, thereby improving the quality of the thermostatic valve.

[0070] like Figure 1 and Figure 2 As shown, the present invention provides a detection device for a thermostatic valve. The thermostatic valve includes multiple water inlets 210 and water outlets 220. The detection device includes a water inlet assembly, an inlet water temperature detection assembly 120, a water outlet assembly 130, and a first outlet water temperature detection component 140. The water inlet assembly can be connected to at least one of the multiple water inlets 210. The inlet water temperature detection assembly 120 is disposed on the water inlet assembly. The water outlet assembly 130 can be connected to the water outlet 220. The first outlet water temperature detection component 140 is disposed on the outlet assembly 130. A first control module 150 is electrically connected to the inlet water temperature detection assembly 120 and the first outlet water temperature detection component 140, respectively.

[0071] In this embodiment, the detection device of the thermostatic valve includes a water inlet assembly, an inlet water temperature detection assembly 120 , a water outlet assembly 130 and a first outlet water temperature detection component 140 .

[0072] When the thermostatic valve needs to be tested, the water inlet end 210 of the thermostatic valve is connected to the water inlet assembly, and the water outlet end 220 of the thermostatic valve is connected to the water outlet assembly 130, so that the detection device of the thermostatic valve can supply water to the thermostatic valve through the water inlet assembly.

[0073] After passing through the thermostatic valve, the water flows out from the water outlet assembly 130 , thereby forming a water path for testing the thermostatic valve.

[0074] A water inlet temperature detection component 120 is provided on the water inlet component of the detection device, and the water inlet temperature detection component 120 can detect the temperature of water flowing through the water inlet component. A first water outlet temperature detection component 140 is provided on the water outlet component 130 of the detection device, and the first water outlet temperature detection component 140 can detect the temperature of water flowing through the water outlet component 130.

[0075] When the detection device detects the thermostatic valve, the temperature detected by the water inlet temperature detection component 120 and the temperature detected by the first water outlet temperature detection component 140 can be sent to the first control module 150. The first control module 150 can determine the position of the valve core of the thermostatic valve based on the temperature difference between the temperature detected by the water inlet temperature detection component 120 and the temperature detected by the first water outlet temperature detection component 140, and then determine whether the valve core of the thermostatic valve can move to a preset position under the drive of the driving component 260, so as to determine whether the driving component 260 and the valve core can work normally, thereby realizing automatic detection of the thermostatic valve, improving the automation level of thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0076] Specifically, when testing the valve core and the driving component 260, the specific testing method is as follows:

[0077] The water inlet assembly is controlled to supply water to the thermostatic valve, and the driving component 260 is controlled to drive the valve core to rotate to a specified position.

[0078] The first control module 150 controls the water inlet temperature detection component 120 to detect the temperature of water flowing through the water inlet component and uses it as the water inlet temperature. The first control module 150 controls the first water outlet temperature detection component 140 to detect the temperature of water flowing through the water outlet component 130 and uses it as the first water outlet temperature.

[0079] The first control module 150 obtains the temperature detected by the water inlet temperature detection component 120 and the temperature detected by the first water outlet temperature detection component 140 respectively.

[0080] The temperature detected by the water inlet temperature detection component 120 is compared with the temperature detected by the first water outlet temperature detection component 140, and the position of the valve core is judged according to the difference between the temperature detected by the water inlet temperature detection component 120 and the temperature detected by the first water outlet temperature detection component 140, and then it is determined whether the driving component 260 drives the valve core to rotate to the specified position, so as to avoid the driving component 260 losing steps when driving the valve core.

[0081] When the difference between the temperature detected by the water inlet temperature detection component 120 and the temperature detected by the first water outlet temperature detection component 140 is less than or equal to 1 degree Celsius, it means that the valve core is in the zero position, that is, the valve core is in the position where the hot water is fully open and the cold water is fully closed, or the valve core is in the position where the hot water is fully closed and the cold water is fully open.

[0082] When the difference between the temperature detected by the water inlet temperature detection component 120 and the temperature detected by the first water outlet temperature detection component 140 is greater than 1 degree Celsius, it means that the valve core is in a position where the hot water is not opened and the cold water is partially opened. The specific opening angle can be determined according to the specific size of the difference between the temperature detected by the water inlet temperature detection component 120 and the temperature detected by the first water outlet temperature detection component 140.

[0083] Specifically, the first outlet water temperature detecting component 140 may be a temperature sensor.

[0084] Specifically, the thermostatic valve may be an electronic thermostatic valve.

[0085] Specifically, Figure 1 The arrows in the figure indicate the direction of water flow in the detection device.

[0086] Example 2:

[0087] This embodiment provides a detection device for a thermostatic valve. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0088] like Figure 1 and Figure 2 As shown, the thermostatic valve further includes a second outlet water temperature detection component 230 . The second outlet water temperature detection component 230 is disposed on the water outlet end 220 and can be electrically connected to the first control module 150 .

[0089] In this embodiment, a second outlet water temperature detection component 230 is provided on the water outlet end 220 of the thermostatic valve. The detection device can also detect whether the second outlet water temperature detection component 230 can work normally during use and whether the installation position is accurate.

[0090] When it is necessary to detect whether the second outlet water temperature detection component 230 can work normally during use and is installed in the correct position, the detection can be performed in the following manner:

[0091] The second outlet water temperature detection component 230 is connected to the first control module 150, and the second outlet water temperature detection component 230 can send the detected temperature to the first control module 150, so that the first control module 150 can determine whether the second outlet water temperature detection component 230 is functioning properly during use and is accurately installed based on the temperature detected by the second outlet water temperature detection component 230. This enables automatic detection of the second outlet water temperature detection component 230, improves the automation level of thermostatic valve detection, and thus increases the speed of thermostatic valve detection. It also prevents human factors from affecting the detection results, improves the reliability of the detection, and improves the accuracy of thermostatic valve detection, thereby improving the quality of the thermostatic valve.

[0092] Specifically, when detecting whether the second outlet water temperature detection component 230 can work normally during use and is installed in the correct position, the detection can be performed in the following manner:

[0093] The water inlet assembly is controlled to supply water to the thermostatic valve, and the driving component 260 is controlled to drive the valve core to rotate to the position where the cold water is fully open and the hot water is fully closed.

[0094] The first control module 150 controls the water inlet temperature detection component 120 to detect the temperature of water flowing through the water inlet component and uses the temperature as the water inlet temperature.

[0095] The first control module 150 controls the first outlet water temperature detection component 140 to detect the temperature of water flowing through the water outlet assembly 130 and uses the temperature as the first outlet water temperature.

[0096] The first control module 150 controls the second outlet water temperature detection component 230 to detect the temperature of water flowing through the outlet end 220 of the thermostatic valve, and uses the temperature as the second outlet water temperature.

[0097] The first control module 150 respectively obtains the temperature detected by the water inlet temperature detection component 120, the temperature detected by the first water outlet temperature detection component 140 and the temperature detected by the second water outlet temperature detection component 230, and compares the temperature detected by the water inlet temperature detection component 120, the temperature detected by the first water outlet temperature detection component 140 and the temperature detected by the second water outlet temperature detection component 230, and then determines whether the second water outlet temperature detection component 230 can work normally during use and whether the installation position is accurate based on the difference between the temperature detected by the water inlet temperature detection component 120, the temperature detected by the first water outlet temperature detection component 140 and the temperature detected by the second water outlet temperature detection component 230.

[0098] When the difference between the temperature detected by the water inlet temperature detection component 120 and the temperature detected by the second water outlet temperature detection component 230, and the difference between the temperature detected by the first water outlet temperature detection component 140 and the temperature detected by the second water outlet temperature detection component 230 are both less than or equal to 1 degree Celsius, the second water outlet temperature detection component 230 can operate normally during use and the installation position is accurate, that is, the second water outlet temperature detection component 230 can accurately detect the temperature of water flowing through the water outlet end 220 of the thermostatic valve.

[0099] When one or both of the difference between the temperature detected by the water inlet temperature detection component 120 and the temperature detected by the second water outlet temperature detection component 230, and the difference between the temperature detected by the first water outlet temperature detection component 140 and the temperature detected by the second water outlet temperature detection component 230 is greater than 1 degree Celsius, the second water outlet temperature detection component 230 cannot operate normally during use, that is, the second water outlet temperature detection component 230 cannot accurately detect the temperature of water flowing through the water outlet end 220 of the thermostatic valve.

[0100] Specifically, the second outlet water temperature detecting component 230 may be a temperature sensor.

[0101] Example 3:

[0102] This embodiment provides a detection device for a thermostatic valve. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0103] like Figure 1 and Figure 2 As shown, the thermostatic valve also includes a valve core, and the multiple water inlet ends 210 also include a first water inlet end 212; the water inlet assembly also includes a first water inlet pipe 112, and the first water inlet pipe 112 can be connected to the first water inlet end 212; the water inlet temperature detection assembly 120 includes a first water inlet temperature detection component 122, and the first water inlet temperature detection component 122 is arranged on the first water inlet pipe 112.

[0104] In this embodiment, a valve core is provided on the thermostatic valve, which can control the opening of the cold water end and the hot water end of the thermostatic valve, thereby adjusting the water temperature. The water inlet component includes a first water inlet pipe 112, which can provide hot water to the first water inlet end 212 of the thermostatic valve. The water inlet temperature detection component 120 includes a first water inlet temperature detection component 122, which can detect the temperature of the hot water flowing through the first water inlet pipe.

[0105] When the valve core and the driving component 260 are tested, the first water inlet pipe 112 is controlled to deliver hot water to the thermostatic valve, and the driving component 260 is controlled to drive the valve core to rotate to the position where the hot water is fully open and the cold water is fully closed, that is, the first position.

[0106] The first control module 150 controls the first inlet water temperature detection component 122 to detect the temperature of the hot water flowing through the first inlet water pipe 112 and use it as the first inlet water temperature.

[0107] The first control module 150 controls the first outlet water temperature detection component 140 to detect the temperature of the hot water flowing through the water outlet assembly 130 and use it as the first outlet water temperature.

[0108] The first control module 150 obtains the temperature detected by the first water inlet temperature detection component 122 and the temperature detected by the first water outlet temperature detection component 140 respectively, and compares the temperature detected by the first water inlet temperature detection component 122 with the temperature detected by the first water outlet temperature detection component 140.

[0109] When the difference between the temperature detected by the first water inlet temperature detection component 122 and the temperature detected by the first water outlet temperature detection component 140 is less than or equal to 1 degree Celsius, it indicates that the valve core is in the zero position, that is, the valve core is in the position where the hot water is fully open and the cold water is fully closed. It can then be detected that the driving component 260 can accurately drive the valve core to rotate to the zero position, thereby achieving automatic detection of the valve core and the driving component 260, improving the automation level of thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0110] Specifically, the first inlet water temperature detecting component 122 may be a temperature sensor.

[0111] Example 4:

[0112] This embodiment provides a detection device for a thermostatic valve. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0114] In this embodiment, the water inlet assembly also includes a second water inlet pipe 114, which can provide cold water to the second water inlet end 214 of the thermostatic valve. The water inlet temperature detection assembly 120 includes a second water inlet temperature detection component 124, which can detect the temperature of the cold water flowing through the second water inlet pipe.

[0115] When the valve core and the driving component 260 are tested, the second water inlet pipe 114 is controlled to deliver cold water to the thermostatic valve, and the driving component 260 is controlled to drive the valve core to rotate to the position where the hot water is fully closed and the cold water is fully opened, that is, the second position.

[0116] The first control module 150 controls the second inlet water temperature detection component 124 to detect the temperature of the cold water flowing through the first inlet water pipe 112 as the second inlet water temperature.

[0117] The first control module 150 controls the first outlet water temperature detection component 140 to detect the temperature of the cold water flowing through the water outlet assembly 130 and use it as the first outlet water temperature.

[0118] The first control module 150 obtains the temperature detected by the second water inlet temperature detection component 124 and the temperature detected by the first water outlet temperature detection component 140, respectively, and compares the temperature detected by the second water inlet temperature detection component 124 with the temperature detected by the first water outlet temperature detection component 140. When the difference between the temperature detected by the second water inlet temperature detection component 124 and the temperature detected by the first water outlet temperature detection component 140 is less than or equal to 1 degree Celsius, it indicates that the valve core is in the position where the cold water is fully open and the hot water is fully closed. It can then be detected that the driving component 260 can accurately drive the valve core to rotate to the second position, thereby achieving automatic detection of the valve core and the driving component 260, improving the automation level of thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0123] In this embodiment, a third water inlet temperature detection component 240 is provided on the thermostatic valve, and the detection device can also detect whether the third water inlet temperature detection component 240 can work normally during use and whether the installation position is accurate.

[0124] When it is necessary to detect whether the third water inlet temperature detection component 240 can work normally during use and is installed in the correct position, the detection can be performed in the following manner:

[0125] The third water inlet temperature detection component 240 is connected to the first control module 150, and then the third water inlet temperature detection component 240 can send the detected temperature to the first control module 150, so that the first control module 150 can determine whether the third water inlet temperature detection component 240 can work normally during use and the installation position is accurate based on the temperature detected by the third water inlet temperature detection component 240.

[0126] This enables automatic detection of the third water inlet temperature detection component 240, improves the automation level of thermostatic valve detection, and thereby increases the speed of thermostatic valve detection. Furthermore, it prevents the impact of human factors on the detection results, thereby increasing detection reliability, improving the accuracy of thermostatic valve detection, and thus improving the quality of the thermostatic valve.

[0127] Specifically, when detecting whether the third inlet water temperature detection component 240 can work normally during use and is installed in an accurate position, the detection can be performed in the following manner:

[0128] The second water inlet pipe 114 is controlled to deliver cold water to the thermostatic valve, and the driving component 260 is controlled to drive the valve core to rotate to the position where the hot water is fully closed and the cold water is fully opened.

[0129] The first control module 150 controls the second inlet water temperature detection component 124 to detect the temperature of the cold water flowing through the first inlet water pipe 112 as the second inlet water temperature.

[0130] The first control module 150 controls the third inlet water temperature detecting component 240 to detect the temperature of the cold water flowing through the second water inlet end 214 of the thermostatic valve, and uses the temperature as the third inlet water temperature.

[0131] The first control module 150 obtains the temperature detected by the second water inlet temperature detection component 124 and the temperature detected by the third water inlet temperature detection component 240 respectively, and compares the temperature detected by the second water inlet temperature detection component 124 and the temperature detected by the third water inlet temperature detection component 240, and then determines whether the third water inlet temperature detection component 240 can work normally during use and the installation position is accurate based on the difference between the temperature detected by the second water inlet temperature detection component 124 and the temperature detected by the third water inlet temperature detection component 240.

[0132] When the difference between the temperature detected by the second water inlet temperature detection component 124 and the temperature detected by the third water inlet temperature detection component 240 is less than or equal to 1 degree Celsius, the third water inlet temperature detection component 240 can operate normally during use and the installation position is accurate, that is, the third water inlet temperature detection component 240 can accurately detect the temperature of water flowing through the water outlet end 220 of the thermostatic valve.

[0133] On the contrary, when the difference between the temperature detected by the second water inlet temperature detection component 124 and the temperature detected by the third water inlet temperature detection component 240 is greater than 1 degree Celsius, the third water inlet temperature detection component 240 cannot work normally during use, that is, the third water inlet temperature detection component 240 cannot accurately detect the temperature of water flowing through the water outlet end 220 of the thermostatic valve.

[0134] Specifically, the third inlet water temperature detecting component 240 may be a temperature sensor.

[0135] Example 6:

[0136] This embodiment provides a detection device for a thermostatic valve. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0137] like Figure 1 and Figure 2 As shown, the thermostatic valve also includes a first flow detection component 250, which is arranged at the second water inlet end 214 and electrically connected to the first control module 150; the detection device also includes a second flow detection component 160, which is arranged on the second water inlet pipe 114 and electrically connected to the first control module 150.

[0138] In this embodiment, the second water inlet end 214 of the thermostatic valve is further provided with a first flow detection component 250. When the first flow detection component 250 needs to be tested, the first flow detection component 250 can be connected to the first control module 150, and then the first flow detection component 250 is tested according to the second flow detection component 160 provided on the second water inlet pipe 114, thereby achieving automatic detection of the first flow detection component 250, improving the automation level of thermostatic valve testing, and thereby increasing the speed of thermostatic valve testing. In addition, the influence of human factors on the test results is avoided, the reliability of the test is higher, the accuracy of thermostatic valve testing is improved, and the quality of the thermostatic valve is improved.

The second water outlet temperature detection component is the second water outlet temperature sensor, the third water inlet temperature detection component is the third water inlet temperature sensor, and the first flow rate detection component is the first flow rate sensor.

[0163] Embodiment 10:

[0164] like Figure 3 As shown, the present invention provides a method for detecting a thermostatic valve, comprising:

[0165] Step 302, controlling the water inlet temperature detection component to detect the water inlet temperature of the water inlet component;

[0166] Step 304, controlling the first outlet water temperature detection component to detect the first outlet water temperature of the water outlet assembly;

[0167] Step 306: Detect the position of the valve core of the thermostatic valve according to the inlet water temperature and the first outlet water temperature.

[0168] In this embodiment, when the thermostatic valve needs to be tested, the water inlet of the thermostatic valve is connected to the water inlet assembly, and the water outlet of the thermostatic valve is connected to the water outlet assembly, so that the detection device of the thermostatic valve can supply water to the thermostatic valve through the water inlet assembly. After passing through the thermostatic valve, the water flows out of the water outlet assembly, thereby forming a water path for testing the thermostatic valve. The water inlet assembly of the detection device is provided with an inlet water temperature detection assembly, which can detect the temperature of water flowing through the water inlet assembly. The water outlet assembly of the detection device is provided with a first outlet water temperature sensor, which can detect the temperature of water flowing through the outlet assembly. When the detection device detects the thermostatic valve, the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature sensor can be sent to the first control module. The first control module can determine the position of the valve core of the thermostatic valve based on the temperature difference between the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature sensor, and then determine whether the valve core of the thermostatic valve can move to a preset position under the drive of the driving component, so as to determine whether the driving component and the valve core can work normally, thereby realizing automatic detection of the thermostatic valve, improving the automation level of thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0169] Specifically, when the valve core and the driving component are tested, the water inlet component is controlled to supply water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to the specified position. The first control module controls the water inlet temperature detection component to detect the temperature of water flowing through the water inlet component, and uses it as the water inlet temperature. The first control module controls the first water outlet temperature sensor to detect the temperature of water flowing through the water outlet component, and uses it as the first water outlet temperature. The first control module obtains the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature sensor respectively, and compares the temperature detected by the water inlet temperature detection component with the temperature detected by the first water outlet temperature sensor, and then judges the position of the valve core according to the difference between the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature sensor, and then determines whether the driving component drives the valve core to rotate to the specified position.

[0170] When the difference between the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature sensor is less than or equal to 1 degree Celsius, it means that the valve core is in the zero position, that is, the valve core is in the position where the hot water is fully open and the cold water is fully closed, or the valve core is in the position where the hot water is fully closed and the cold water is fully open.

[0171] When the difference between the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature sensor is greater than 1 degree Celsius, it means that the valve core is in a position where the hot water is not open and the cold water is partially open. The specific opening angle can be determined according to the specific size of the difference between the temperature detected by the water inlet temperature detection component and the temperature detected by the first water outlet temperature sensor.

[0172] Example 11:

[0173] like Figure 4 As shown, the present invention provides a method for detecting a thermostatic valve, comprising:

[0174] Step 402, controlling the water inlet temperature detection component to detect the water inlet temperature of the water inlet component;

[0175] Step 404, controlling the first outlet water temperature detection component to detect the first outlet water temperature of the water outlet assembly;

[0176] Step 406, detecting the position of the valve core of the thermostatic valve according to the inlet water temperature and the first outlet water temperature;

[0177] Step 408, obtaining a second outlet water temperature from a second outlet water temperature detection component;

[0178] Step 410: Detect whether the second outlet water temperature detection component works normally based on the first outlet water temperature and the second outlet water temperature.

[0179] In this embodiment, a second outlet water temperature sensor is provided at the water outlet of the thermostatic valve, and the detection device can also detect whether the second outlet water temperature sensor can operate normally during use and is accurately installed. When it is necessary to detect whether the second outlet water temperature sensor can operate normally during use and is accurately installed, the second outlet water temperature sensor can be connected to the first control module, and the second outlet water temperature sensor can send the detected temperature to the first control module, so that the first control module can determine whether the second outlet water temperature sensor can operate normally during use and is accurately installed based on the temperature detected by the second outlet water temperature sensor, thereby achieving automatic detection of the second outlet water temperature sensor, improving the degree of automation of thermostatic valve detection, and thus improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the detection results, and the reliability of the detection is higher, improving the detection accuracy of the thermostatic valve, and thus improving the quality of the thermostatic valve.

[0180] Specifically, when detecting whether the second water outlet temperature sensor can work normally during use and the installation position is accurate, the water inlet component is controlled to supply water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to the position where the cold water is fully open and the hot water is fully closed. The first control module controls the water inlet temperature detection component to detect the temperature of the water flowing through the water inlet component, and uses it as the water inlet temperature. The first control module controls the first water outlet temperature sensor to detect the temperature of the water flowing through the water outlet component, and uses it as the first water outlet temperature. The first control module controls the second water outlet temperature sensor to detect the temperature of the water flowing through the water outlet end of the thermostatic valve, and uses it as the second water outlet temperature. The module respectively obtains the temperature detected by the water inlet temperature detection component, the temperature detected by the first water outlet temperature sensor and the temperature detected by the second water outlet temperature sensor, and compares the temperature detected by the water inlet temperature detection component, the temperature detected by the first water outlet temperature sensor and the temperature detected by the second water outlet temperature sensor, and then determines whether the second water outlet temperature sensor can work normally during use and the installation position is accurate according to the difference between the temperature detected by the water inlet temperature detection component, the temperature detected by the first water outlet temperature sensor and the temperature detected by the second water outlet temperature sensor.

[0181] When the difference between the temperature detected by the water inlet temperature detection component and the temperature detected by the second water outlet temperature sensor, and the difference between the temperature detected by the first water outlet temperature sensor and the second water outlet temperature sensor are both less than or equal to 1 degree Celsius, the second water outlet temperature sensor can operate normally during use and the installation position is accurate, that is, the second water outlet temperature sensor can accurately detect the temperature of water flowing through the water outlet end of the thermostatic valve.

[0182] When one or both of the difference between the temperature detected by the water inlet temperature detection component and the temperature detected by the second water outlet temperature sensor, and the difference between the temperature detected by the first water outlet temperature sensor and the temperature detected by the second water outlet temperature sensor is greater than 1 degree Celsius, the second water outlet temperature sensor cannot work normally during use, that is, the second water outlet temperature sensor cannot accurately detect the temperature of water flowing through the water outlet end of the thermostatic valve.

[0183] Example 12:

[0184] like Figure 5 As shown, the present invention provides a method for detecting a thermostatic valve, comprising:

[0185] Step 502: Control the water inlet temperature detection component to detect the water inlet temperature of the water inlet component, where the water inlet temperature includes a first water inlet temperature;

[0186] Step 504, controlling the first outlet water temperature detection component to detect the first outlet water temperature of the water outlet assembly;

[0187] Step 506: Detect whether the valve core of the thermostatic valve is in the first position according to the first water inlet temperature and the first water outlet temperature.

[0188] In this embodiment, a valve core is provided on the thermostatic valve, which can control the opening of the cold water end and the hot water end of the thermostatic valve, thereby adjusting the water temperature. The water inlet component includes a first water inlet pipe, which can provide hot water to the first water inlet end of the thermostatic valve. The water inlet temperature detection component includes a first water inlet temperature sensor, which can detect the temperature of the hot water flowing through the first water inlet pipe.

[0189] When testing the valve core and the driving component, the first water inlet pipe is controlled to supply hot water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to a position where the hot water is fully open and the cold water is fully closed, i.e., the first position. The first control module controls the first water inlet temperature sensor to detect the temperature of the hot water flowing through the first water inlet pipe, and uses it as the first water inlet temperature. The first control module controls the first water outlet temperature sensor to detect the temperature of the hot water flowing through the water outlet assembly, and uses it as the first water outlet temperature. The first control module obtains the temperature detected by the first water inlet temperature sensor and the temperature detected by the first water outlet temperature sensor, respectively, and compares the temperature detected by the first water inlet temperature sensor with the temperature detected by the first water outlet temperature sensor. When the difference between the temperature detected by the first water inlet temperature sensor and the temperature detected by the first water outlet temperature sensor is less than or equal to 1 degree Celsius, it indicates that the valve core is in the zero position, i.e., the valve core is in the position where the hot water is fully open and the cold water is fully closed. Therefore, it can be detected that the driving component can accurately drive the valve core to rotate to the zero position, thereby realizing automatic testing of the valve core and the driving component, improving the automation level of thermostatic valve testing, and thereby improving the testing speed of the thermostatic valve. It also avoids the influence of human factors on the test results, makes the test more reliable, improves the detection accuracy of the thermostatic valve, and thus improves the quality of the thermostatic valve.

[0190] Example 13:

[0191] like Figure 6 As shown, the present invention provides a method for detecting a thermostatic valve, comprising:

[0192] Step 602, controlling the water inlet temperature detection component to detect the water inlet temperature of the water inlet component, where the water inlet temperature includes a second water inlet temperature;

[0193] Step 604, controlling the first outlet water temperature detection component to detect the first outlet water temperature of the water outlet assembly;

[0194] Step 606: Detect whether the valve core of the thermostatic valve is in the second position according to the second water inlet temperature and the first water outlet temperature.

[0195] In this embodiment, the water inlet component also includes a second water inlet pipe, which can provide cold water to the second water inlet end of the thermostatic valve. The water inlet temperature detection component includes a second water inlet temperature sensor, which can detect the temperature of the cold water flowing through the second water inlet pipe.

[0196] When testing the valve core and the driving component, the second water inlet pipe is controlled to supply cold water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to a position where the hot water is fully closed and the cold water is fully open, i.e., the second position. The first control module controls the second water inlet temperature sensor to detect the temperature of the cold water flowing through the first water inlet pipe, and uses it as the second water inlet temperature. The first control module controls the first water outlet temperature sensor to detect the temperature of the cold water flowing through the water outlet assembly, and uses it as the first water outlet temperature. The first control module obtains the temperature detected by the second water inlet temperature sensor and the temperature detected by the first water outlet temperature sensor, respectively, and compares the temperature detected by the second water inlet temperature sensor with the temperature detected by the first water outlet temperature sensor. When the difference between the temperature detected by the second water inlet temperature sensor and the temperature detected by the first water outlet temperature sensor is less than or equal to 1 degree Celsius, it indicates that the valve core is in the position where the cold water is fully open and the hot water is fully closed. It can then be detected that the driving component can accurately drive the valve core to rotate to the second position, thereby realizing automatic detection of the valve core and the driving component, improving the automation level of thermostatic valve detection, and thereby improving the detection speed of the thermostatic valve. It also avoids the influence of human factors on the test results, makes the test more reliable, improves the detection accuracy of the thermostatic valve, and thus improves the quality of the thermostatic valve.

[0197] Example 14:

[0198] like Figure 7 As shown, the present invention provides a method for detecting a thermostatic valve, comprising:

[0199] Step 702: Control the water inlet temperature detection component to detect the water inlet temperature of the water inlet component, where the water inlet temperature includes a second water inlet temperature;

[0200] Step 704, controlling the first outlet water temperature detection component to detect the first outlet water temperature of the water outlet assembly;

[0201] Step 706, obtaining a second outlet water temperature from a second outlet water temperature detection component;

[0202] Step 708, obtaining a third inlet water temperature from a third inlet water temperature detection component;

[0203] Step 710: Detect whether the component is working normally according to the second inlet water temperature and the third inlet water temperature.

[0204] In this embodiment, a third water inlet temperature sensor is provided on the thermostatic valve, and the detection device can also detect whether the third water inlet temperature sensor is functioning properly during use and is accurately installed. When it is necessary to detect whether the third water inlet temperature sensor is functioning properly during use and is accurately installed, the third water inlet temperature sensor can be connected to the first control module, and the third water inlet temperature sensor can then transmit the detected temperature to the first control module. The first control module can then determine whether the third water inlet temperature sensor is functioning properly during use and is accurately installed based on the temperature detected by the third water inlet temperature sensor, thereby achieving automatic detection of the third water inlet temperature sensor, improving the automation level of thermostatic valve detection, and thereby increasing the detection speed of the thermostatic valve. This also prevents human factors from affecting the detection results, resulting in higher detection reliability, improved detection accuracy of the thermostatic valve, and thus improved thermostatic valve quality.

[0205] Specifically, when detecting whether the third water inlet temperature sensor can work normally during use and the installation position is accurate, the second water inlet pipeline is controlled to deliver cold water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to the position where the hot water is fully closed and the cold water is fully open. The first control module controls the second water inlet temperature sensor to detect the temperature of the cold water flowing through the first water inlet pipeline, and uses it as the second water inlet temperature. The first control module controls the third water inlet temperature sensor to detect the temperature of the cold water flowing through the second water inlet end of the thermostatic valve, and uses it as the third water inlet temperature.

[0206] The first control module respectively obtains the temperature detected by the second water inlet temperature sensor and the temperature detected by the third water inlet temperature sensor, and compares the temperature detected by the second water inlet temperature sensor with the temperature detected by the third water inlet temperature sensor, and then determines whether the third water inlet temperature sensor can work normally during use and is installed in an accurate position based on the difference between the temperature detected by the second water inlet temperature sensor and the temperature detected by the third water inlet temperature sensor.

[0207] When the difference between the temperature detected by the second water inlet temperature sensor and the temperature detected by the third water inlet temperature sensor is less than or equal to 1 degree Celsius, the third water inlet temperature sensor can operate normally during use and the installation position is accurate, that is, the third water inlet temperature sensor can accurately detect the temperature of water flowing through the water outlet end of the thermostatic valve.

[0208] On the contrary, when the difference between the temperature detected by the second water inlet temperature sensor and the temperature detected by the third water inlet temperature sensor is greater than 1 degree Celsius, the third water inlet temperature sensor cannot work normally during use, that is, the third water inlet temperature sensor cannot accurately detect the temperature of water flowing through the water outlet end of the thermostatic valve.

[0209] Embodiment 15:

[0210] like Figure 8 As shown, the present invention provides a method for detecting a thermostatic valve, comprising:

[0211] Step 802, controlling the water inlet temperature detection component to detect the water inlet temperature of the water inlet component, where the water inlet temperature includes a second water inlet temperature;

[0212] Step 804, controlling the first outlet water temperature detection component to detect the first outlet water temperature of the water outlet assembly;

[0213] Step 806, obtaining a second outlet water temperature from a second outlet water temperature detection component;

[0214] Step 808, obtaining a third inlet water temperature from a third inlet water temperature detection component;

[0215] Step 810 , detecting whether the valve core of the thermostatic valve is in the second position according to the second water inlet temperature, the third water inlet temperature, the first water outlet temperature, and the second water outlet temperature.

[0216] In this embodiment, when detecting whether the valve core of the thermostatic valve is in the second position, the second water inlet pipe is controlled to supply cold water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to the position where the hot water is fully closed and the cold water is fully open. The first control module controls the second water inlet temperature sensor to detect the temperature of the cold water flowing through the first water inlet pipe, and uses it as the second water inlet temperature. The first control module controls the first water outlet temperature sensor to detect the temperature of the cold water flowing through the water outlet component, and uses it as the first water outlet temperature. The first control module controls the third water inlet temperature sensor to detect the temperature of the cold water flowing through the second water inlet end of the thermostatic valve, and uses it as the third water inlet temperature. The first control module controls the second water outlet temperature sensor to detect the temperature of the water flowing through the water outlet end of the thermostatic valve, and uses it as the second water outlet temperature.

[0217] The first control module respectively obtains the temperature detected by the second water inlet temperature sensor and the temperature detected by the third water inlet temperature sensor, compares the temperature detected by the second water inlet temperature sensor with the temperature detected by the third water inlet temperature sensor, and then determines whether the valve core of the thermostatic valve is in the second position according to the difference between the temperature detected by the second water inlet temperature sensor and the temperature detected by the third water inlet temperature sensor.

[0218] When the difference between the temperature detected by the second water inlet temperature sensor and the temperature detected by the third water inlet temperature sensor, the difference between the temperature detected by the first water outlet temperature sensor and the temperature detected by the third water inlet temperature sensor, and the difference between the temperature detected by the second water outlet temperature sensor and the temperature detected by the third water inlet temperature sensor are all less than or equal to 1 degree Celsius, it means that the valve core is in the position where the cold water is fully open and the hot water is fully closed. It can be detected that the driving component can accurately drive the valve core to rotate to the second position, and automatic detection of the valve core and the driving component can be realized, so that the position detection of the valve core is more accurate.

[0219] Example 16:

[0220] like Figure 9 As shown, the present invention provides a method for detecting a thermostatic valve, comprising:

[0221] Step 902: Control the driving component to drive the valve core to rotate to the second position;

[0222] Step 904: After a first preset delay, obtain a first flow rate detected by a first flow rate detection component;

[0223] Step 906, controlling the second flow detection component to detect a second flow in the second water inlet pipe;

[0224] Step 908: Detect whether the first flow detection component works normally based on the first flow and the second flow.

[0225] In this embodiment, a first flow sensor is further provided at the second water inlet end of the thermostatic valve. When the first flow sensor needs to be tested, the first flow sensor can be connected to the first control module, and then the first flow sensor is tested based on the second flow sensor provided on the second water inlet pipe. This enables automatic testing of the first flow sensor, improves the automation level of thermostatic valve testing, and thereby increases the speed of thermostatic valve testing. This also prevents human factors from affecting the test results, resulting in higher test reliability, improved test accuracy, and thus improved thermostatic valve quality.

[0226] When detecting the first flow sensor, the second water inlet pipe is controlled to supply cold water to the thermostatic valve, and the driving component is controlled to drive the valve core to rotate to the position where the hot water is fully closed and the cold water is fully opened. After a first preset delay, the first control module controls the first flow sensor to detect the flow of cold water flowing through the second water inlet end, and uses it as the first flow rate. The first control module controls the second flow sensor to detect the flow of cold water flowing through the second water inlet pipe, and uses it as the second flow rate. The first control module obtains the flow rate detected by the first flow sensor and the flow rate detected by the second flow sensor respectively, and compares the flow rate detected by the first flow sensor with the flow rate detected by the second flow sensor. If the flow rate detected by the first flow sensor and the flow rate detected by the second flow sensor are within a 10% error range, then the first flow sensor can operate normally during use and is accurately installed, that is, the first flow sensor can accurately detect the flow rate of cold water flowing through the second water inlet end.

[0231] Step 1006, controlling the first outlet water temperature detection component to detect the first outlet water temperature of the water outlet assembly;

[0232] Step 1008: detecting the position of the valve core of the thermostatic valve according to the inlet water temperature and the first outlet water temperature;

[0233] Step 1010: Determine whether the driving component has lost steps based on the position of the valve core.

[0234] In this embodiment, the first control module transmits the maximum rotation angle of the thermostatic valve spool to the second control module. The second control module drives the stepper motor to rotate based on the final pulse number calculated by multiplying the maximum rotation angle by the pulse coefficient required per degree of the thermostatic valve stepper motor. The specific pulse number is sent to control the stepper motor's rotation, and a temperature sensor is used to determine whether the stepper motor has lost steps. This enables automatic detection of the drive components, improves the automation level of thermostatic valve detection, and thus increases the speed of thermostatic valve detection. This also prevents human factors from affecting the detection results, improves detection reliability, and enhances the accuracy of thermostatic valve detection, thereby improving the quality of the thermostatic valve.
