Referring to fig. 1 and 2, in some embodiments, a first end 271 of the conveying pipe extends into the storage chamber 11, a second end 273 of the conveying pipe is correspondingly communicated with the storage chamber 11, and a water pump 23 is used to pump the liquid material through the first end 271 of the conveying pipe and back to the storage chamber 11 through the second end 273 of the conveying pipe.

In some embodiments, the storage cavity 11 has an opening, i.e. the storage element 10 is provided with an opening. The first end 271 of the transfer line extends into the storage chamber 11 to withdraw liquid material from the storage chamber 11. At this time, in one embodiment, the second end 273 of the conveying pipe may be disposed at an interval corresponding to the opening of the storage cavity 11, and the water pump 23 pumps the liquid material back into the storage cavity 11 through the second end 273 of the conveying pipe, so that on one hand, the conveying pipe 27 can form a loop, and thus, the liquid material does not need to be added into the storage cavity 11 for multiple times, so as to simplify the operation of the testing device 100; on the other hand, corrosion of the second end 273 of the transfer line by the liquid material can be avoided, thereby ensuring proper operation of the test device 100. In another embodiment, the second end 273 of the conveying pipe can extend into the storage cavity 11, and compared with the second end 273 of the conveying pipe and the opening of the storage cavity 11 which are correspondingly spaced, the present embodiment can also prevent the liquid material from being splashed when the water pump 23 pumps the liquid material back into the storage cavity 11 through the second end 273 of the conveying pipe, thereby reducing the production cost.

In other embodiments, the storage cavity 11 may be a sealed cavity, i.e., the storage element 10 may be a sealed structure. At this time, the second end 273 of the conveying pipe can extend into the storage cavity 11, so that on one hand, the conveying pipe 27 can form a loop, and further, the liquid material does not need to be added into the storage cavity 11 for multiple times, so that the operation of the testing device 100 is simplified; on the other hand, foreign matters such as external dust can be prevented from entering the storage cavity 11, so that liquid materials are polluted, and the accuracy of performance test of the electromagnetic valve 21 to be tested by the testing device 100 is ensured.

In some embodiments, the solenoid valve 21 to be measured, the flow meter 25 and the water pump 23 may be sequentially disposed on the delivery line 27 along the direction from the first end 271 of the delivery line to the second end 273 of the delivery line.

Specifically, the storage chamber 11 is communicated with the inlet 211 of the solenoid valve to be tested, the outlet 213 of the solenoid valve to be tested is communicated with the inlet 251 of the flowmeter, the outlet 253 of the flowmeter is communicated with the inlet 231 of the water pump, and the outlet 233 of the water pump is correspondingly communicated with the storage chamber 11, so that the liquid material in the storage chamber 11 can be pumped back into the storage chamber 11 by the water pump 23 after sequentially passing through the solenoid valve to be tested 21, the flowmeter 25 and the water pump 23 under the condition that both the solenoid valve to be tested 21 and the water pump 23 are opened. The flowmeter 25 is arranged between the electromagnetic valve 21 to be tested and the water pump 23, so that the influence of the water pump 23 on the flow rate of the liquid material in the conveying pipeline 27 can be reduced or even avoided, the accuracy of flow data of the liquid material on the conveying pipeline 27 detected by the flowmeter 25 is further ensured, and the accuracy of the performance of the electromagnetic valve 21 to be tested detected by the testing device 100 is further ensured.

In other embodiments, the solenoid valve 21 to be tested, the water pump 23 and the flow meter 25 may be sequentially disposed on the delivery line 27 along the direction from the first end 271 of the delivery line to the second end 273 of the delivery line.

Specifically, the storage chamber 11 is communicated with the inlet 211 of the solenoid valve to be tested, the outlet 213 of the solenoid valve to be tested is communicated with the inlet 231 of the water pump, the outlet 233 of the water pump is communicated with the inlet 251 of the flowmeter, and the outlet 253 of the flowmeter is correspondingly communicated with the storage chamber 11, so that the liquid material in the storage chamber 11 can be pumped into the storage chamber 11 by the water pump 23 after sequentially passing through the solenoid valve 21 to be tested, the water pump 23 and the flowmeter 25 under the condition that both the solenoid valve 21 to be tested and the water pump 23 are opened. The water pump 23 is arranged between the electromagnetic valve 21 to be tested and the flowmeter 25, so that the situation that the distance between the electromagnetic valve 21 to be tested and the water pump 23 on the conveying pipeline 27 is too far can be avoided, the water pump 23 cannot normally extract liquid materials in the storage cavity 11, and the normal operation of the testing device 100 is further ensured.

Referring to fig. 2, in some embodiments, the solenoid valve 21 to be measured is a multi-position solenoid valve, and the solenoid valve 21 to be measured includes a plurality of inlets 211 and an outlet 213. The inlets 213 of each solenoid valve to be tested can be controlled to be opened or closed, and the inlets 211 of the solenoid valves to be tested are communicated with the outlets 213 of the solenoid valves to be tested.

In certain embodiments, the transfer line 27 includes a plurality of feed lines 275, a plurality of connecting lines 277, and an outlet line 279. The plurality of feeding pipes 275 correspond to the inlets 211 of the plurality of solenoid valves to be measured, and one end of each feeding pipe 275 is communicated with the storage chamber 11, and the other end is communicated with the inlet 211 of one solenoid valve to be measured. The connecting pipes 277 are respectively disposed between the outlet 213 of the solenoid valve to be tested, the water pump 23 and the flow meter 25 to communicate the solenoid valve to be tested 21, the water pump 23 and the flow meter 25. One end of the discharge pipe 279 is communicated with the outlet 233 of the water pump, the other end is communicated with the storage chamber 11, and the discharge pipe 279 is used for pumping liquid material extracted from the storage chamber 11 by the water pump 23 back into the storage chamber 11.

In the case that the solenoid valve 21 to be tested, the flow meter 25 and the water pump 23 are sequentially disposed on the conveying pipeline 27 along the direction from the first end 271 to the second end 273 of the conveying pipeline in fig. 1, two connecting pipes 277 may be disposed between the outlet 213 of the solenoid valve to be tested and the inlet 251 of the flow meter, and between the outlet 253 of the flow meter and the inlet 231 of the water pump, respectively. In some embodiments, the feeding pipe 275, the connecting pipe 277 and the discharging pipe 279 are made of bendable and corrosion-resistant materials, such as hard polyvinyl chloride, rubber, etc., so that on one hand, the feeding pipe 275, the connecting pipe 277 and the discharging pipe 279 can be prevented from being damaged due to corrosion of liquid materials, and normal operation of the testing device 100 is ensured; on the other hand, the bendable conveying pipe 27 can reduce the space occupied by the conveying assembly 20 compared with the non-bendable conveying pipe 27, thereby realizing miniaturization of the test device 100.

In some embodiments, the inlet 211 of one solenoid valve to be tested is connected to the atmosphere, and when the inlet 211 of the other solenoid valve to be tested is closed and the inlet 211 of the solenoid valve to be tested which is connected to the atmosphere is opened, the water pump 23 is further configured to pump the atmosphere through the inlet 211 of the solenoid valve to be tested which is connected to the atmosphere, so as to empty the liquid material in the conveying pipeline 27, thereby preventing the residual liquid material in the conveying pipeline 27 from affecting the flow data detected by the flowmeter 25, and ensuring the accuracy of the performance of the solenoid valve to be tested 21 detected by the testing device 100.

Referring to fig. 2, in some embodiments, the test apparatus 100 further includes a control component 30. The control assembly 30 is electrically connected with the solenoid valve 21 to be tested, the water pump 23 and the flowmeter 25, and the control assembly 30 is used for controlling the start and stop of the solenoid valve 21 to be tested and the water pump 23 and obtaining flow data detected by the flowmeter 25.

In some embodiments, the solenoid valve 21 to be tested further includes a plurality of valve spools 215 corresponding to the inlets 211 of the plurality of solenoid valves to be tested, each valve spool 215 is used for switching the conducting state of the inlet 211 of the corresponding solenoid valve to be tested and the outlet 213 of the solenoid valve to be tested, and each valve spool 215, the inlet 211 of the corresponding solenoid valve to be tested and the outlet 213 of the solenoid valve to be tested form a conducting position 210. Wherein the control assembly 30 is capable of controlling the opening or closing of the delivery line 27 by controlling the movement of each spool 215 to control the conductive state of the inlet 211 of the corresponding solenoid valve under test and the outlet 213 of the solenoid valve under test, i.e., to control the opening or closing of the conductive bit 210. For example, the control assembly 30 controls one valve core 215 to move, so that the inlet 211 of the corresponding solenoid valve to be tested and the outlet 213 of the solenoid valve to be tested are conducted, and the conveying pipeline 27 is opened, at this time, the water pump 23 pumps the liquid material in the storage cavity 11, and the liquid material can be pumped back into the storage cavity 11 after passing through the corresponding feeding pipeline 275, the connecting pipeline 277 and the discharging pipeline 279 in sequence.

In some embodiments, the solenoid valve 21 to be tested and the water pump 23 are in a start-stop period, the solenoid valve 21 to be tested is used for opening an inlet 211 of one of the solenoid valves to be tested, the water pump 23 is used for extracting liquid material in a feed pipeline 275 corresponding to the inlet 211 of the solenoid valve to be tested which is opened, the flow meter 25 is used for detecting flow data of the liquid material once, and a plurality of flow data in a predetermined start-stop period are used for reflecting conduction performance of a conduction bit 210 formed by the opened inlet 211. It should be noted that, in some embodiments, one start-stop period is a period in which the control unit 30 controls the water pump 23 to be turned on and off once.

Specifically, in a start-stop period, under the condition that the water pump 23 pumps liquid material, the inlet 211 of one of the solenoid valves 21 to be tested is opened, the flow meter 25 detects flow data of the primary liquid material, and the control assembly 30 is connected with the flow meter 25, so that the flow data detected by the flow meter 25 can be obtained and recorded. During a plurality of start-stop periods, the flow meter 25 can detect the obtained flow data of the liquid material for a plurality of times, and the control assembly 30 judges the conduction performance of the conduction bit 210 formed by the inlet 211 of the opened solenoid valve to be tested according to the flow data for a plurality of times. Specifically, in one embodiment, there is a difference between the initial flow data and the final flow data in the multiple flow data, where the conduction performance of the conduction bit 210 is poor if the absolute value of the difference is greater than the first threshold, and where the conduction performance of the conduction bit 210 is better if the difference is less than the first threshold. When the absolute value of the difference value between the initial flow data and the final flow data in the multiple flow data is greater than the first threshold, if the initial flow data is greater than the final flow data, it indicates that the valve core 215 in the conducting bit 210 may be blocked; if the initial flow data is smaller than the last flow data, it indicates that the valve element 215 in the conducting bit 210 may wear out.

In some embodiments, the time of the start-stop periods, the power of the water pump 23 and the extracted liquid material are the same, so that the accuracy of the flow data detected by the flow meter 25 can be ensured, and the conduction performance of the conduction bit 210 can be accurately reflected.

In some embodiments, the number of start-stop cycles may be a preset constant value, for example, one thousand start-stop cycles may be preset, that is, the control component 30 controls the water pump 23 to start and stop one thousand times, and in the case that the water pump 23 is turned on, the inlets 211 of one or more solenoid valves to be tested 21 are turned on, so that the flow meter 25 can detect and obtain flow data of one thousand liquid materials, and the control component 30 determines the conduction performance of the conduction bit 210 formed by the turned on inlet 211 of the solenoid valve to be tested according to the one thousand flow data.

Referring to fig. 2 again, in some embodiments, the solenoid valve 21 to be tested is used to open the inlets 211 of the plurality of solenoid valves to be tested in one start-stop period, the water pump 23 is used to pump the liquid material in the plurality of feeding pipes 275 corresponding to the inlets 211 of the plurality of solenoid valves to be tested opened, the flow meter 25 is used to detect the flow data of the liquid material once, and the plurality of flow data in the predetermined start-stop periods are used to reflect the conduction performance of the conduction bit 210 formed by the inlets 211 of the plurality of solenoid valves to be tested opened. The start-stop period in this embodiment is substantially the same as that in the above embodiment, except that:

in this embodiment, in a start-stop period, under the condition that the water pump 23 pumps the liquid material, the inlets 211 of a plurality of solenoid valves to be tested in the solenoid valves to be tested 21 are opened, the flow rate data of the primary liquid material detected by the flow meter 25 is connected to the flow meter 25, so that the flow rate data detected by the flow meter 25 can be acquired and recorded. During a plurality of start-stop periods, the flow meter 25 can detect the obtained flow data of the liquid material for a plurality of times, and the control assembly 30 judges the conduction performance of the conduction bit 210 formed by the inlet 211 of the opened solenoid valve to be tested according to the flow data for a plurality of times. Specifically, in one embodiment, there is a difference between the initial flow data and the final flow data in the multiple flow data, where the conduction performance of the conduction bit 210 is poor if the absolute value of the difference is greater than the second threshold, and where the conduction performance of the conduction bit 210 is better if the difference is less than the second threshold. When the absolute value of the difference value between the initial flow data and the final flow data in the multiple flow data is greater than the second threshold, if the initial flow data is greater than the final flow data, it indicates that the valve core 215 in the conducting bit 210 may be blocked; if the initial flow data is smaller than the last flow data, it indicates that the valve element 215 in the conducting bit 210 may wear out. It should be noted that, in some embodiments, the second threshold range may be set according to a specific usage condition of the solenoid valve 21 to be tested, so as to evaluate the performance of the solenoid valve 21 to be tested.

Specifically, the storage element 10 may be disposed on the top of the carrier 41, so as to avoid direct contact between the storage element 10 and the ground, further prevent the liquid material in the storage element 10 from being polluted, and ensure the accuracy of the performance test of the electromagnetic valve 21 to be tested by the testing device 100. The storage part 10 is disposed on the first side 431 of the supporting part, and the solenoid valve 21 to be tested, the water pump 23 and the flowmeter 25 are disposed on the second side 433 of the supporting part, so as to avoid damage caused by contact of the solenoid valve 21 to be tested, the water pump 23 and the flowmeter 25 with the liquid material, and ensure normal operation of the testing device 100.
