[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0024] like Figure 1-Figure 4 As shown, the utility model provides a device for testing the pipeline blockage of a piston tube, including a testing mechanism and a testing station 4, wherein the testing station 4 is provided with a positioning portion for positioning the piston tube 5; the testing mechanism includes an exhaust purifier 1, a testing module 2 and a moving portion, wherein the number of the testing modules 2 is multiple and arranged in parallel; the inlet end of the test pipeline 21 of the testing module 2 is connected to the exhaust purifier 1, and the outlet end of the test pipeline 21 is connected to the moving portion, and the moving portion drives the outlet end of the test pipeline 21 to move toward or away from the testing station 4.

[0025] Through the cooperation of the moving part and the test module 2, the automatic docking and testing of the pipeline 53 of the piston tube 5 and the test module 2 are realized without human intervention. Moreover, the parallel arrangement of multiple test modules 2 can perform blockage tests on the pipelines 53 of multiple piston tubes 5 at the same time, greatly improving the test efficiency.

[0026] Clean gas is provided by the exhaust purifier 1, so that the gas used in the test process is free of impurities, thereby avoiding the influence of impurities on the test results. The exhaust purifier 1 adopts the existing technology, which will not be described in detail here.

[0027] As an optional implementation, the test module 2 also includes a solenoid valve 22, a speed control valve 23, a pressure switch 24 and a test head 25. The solenoid valve 22, the speed control valve 23 and the pressure switch 24 are arranged in sequence on the test pipeline 21 along the gas flow direction. The test head 25 has a through test channel 251. The inlet end of the test channel 251 is connected to the outlet end of the test pipeline 21, and the outlet end of the test channel 251 faces the test station 4.

[0028] Through the coordinated action of the exhaust cleaner 1 , the test pipeline 21 , the solenoid valve 22 , the speed control valve 23 , the pressure switch 24 and the test head 25 , the pipeline 53 can be accurately tested for blockage pressure.

[0029] The test pipeline 21 connects the exhaust cleaner 1 and the test head 25 to deliver clean gas to the pipeline 53 of the piston tube 5 for a blockage test.

[0030] The test head 25 has a through test channel 251 , the inlet end of the test channel 251 is connected to the outlet end of the test pipeline 21 so that the gas can smoothly enter the pipeline 53 of the piston tube 5 .

[0031] The function of the solenoid valve 22 is to control the on-off of the airflow in the test pipeline 21. When the solenoid valve 22 is opened, the clean gas output by the exhaust cleaner 1 is allowed to flow into the test pipeline 21 and the pipeline 53 of the piston tube 5. When the solenoid valve 22 is closed, the gas supply to the pipeline 53 is stopped.

[0032] The function of the speed control valve 23 is to adjust the flow rate and speed of the gas in the test pipeline 21 to meet different test requirements.

[0033] The function of the pressure switch 24 is to monitor the pressure changes in the test pipeline 21 in real time. When the pressure in the pipeline 53 gradually rises and reaches the preset blocking pressure threshold, it means that the gas encounters the blockage of particles in the pipeline 53 of the piston tube 5. The pressure switch 24 records the data and triggers the blocking signal, notifying the operator that the pipeline 53 of the piston tube 5 is blocked. If the pressure in the pipeline 53 is maintained within the preset normal range, the pressure switch 24 records the data and triggers the normal signal, notifying the operator that the pipeline 53 of the piston tube 5 is not blocked.

[0034] When a blockage test is required, that is, the pipeline 53 and the test channel 251 are in a connected state, the gas flow and speed in the test pipeline 21 are preset on the speed control valve 23 according to the test needs, and the blockage pressure threshold and normal pressure range are preset on the pressure switch 24. Then, the exhaust cleaner 1 is started, and the gas pressure output from the exhaust cleaner 1 to the test pipeline 21 is adjusted by the pressure reducing valve, and then the solenoid valve 22 of the corresponding test module 2 is opened, and the clean gas flows from the exhaust cleaner 1 into the test pipeline 21, and then enters the pipeline 53 of the piston tube 5. The pressure switch 24 monitors the pressure change in the test pipeline 21 in real time. If the pressure in the pipeline 53 gradually rises and reaches the preset blockage pressure threshold, it means that the gas encounters the blockage of particles in the pipeline 53 of the piston tube 5. The pressure switch 24 records the data and triggers the blockage signal, notifying the operator that the pipeline 53 of the piston tube 5 is blocked. If the pressure in the pipeline 53 is maintained within the preset normal range, the pressure switch 24 records the data and triggers the normal signal, notifying the operator that the pipeline 53 of the piston tube 5 is not blocked.

[0035] It should be noted that the solenoid valve 22, the speed control valve 23 and the pressure switch 24 are prior arts and will not be described in detail herein.

[0036] As an optional implementation, the inlet ends of all the test pipelines 21 are connected to the exhaust purifier 1 through the pipeline connector 6 .

[0037] Furthermore, a pressure reducing valve is provided on the pipeline between the exhaust purifier 1 and the pipeline connector 6 .

[0038] The function of the pressure reducing valve is to adjust the gas pressure output to the test pipeline 21 to ensure that the gas pressure remains within a safe and stable range, thereby playing a certain protective role for the test module 2 .

[0039] All the test pipelines 21 obtain clean gas from the same exhaust purifier 1, so that each test pipeline 21 obtains gas with consistent quality and cleanliness, thereby improving the accuracy and consistency of the test.

[0040] As an optional implementation, the number of the test modules 2 is four.

[0041] Furthermore, the number of the positioning parts is also four, and they are arranged in a one-to-one correspondence with the test modules 2.

[0042] With this arrangement, the four piston tubes 5 can be tested for blockage at one time, which effectively reduces the test time and improves the test efficiency.

[0043] As an optional implementation, the moving part includes a cylinder 3, the action end of the cylinder 3 is connected to the test head 25 through a connecting plate 26, and the cylinder 3 performs telescopic movement to drive the test channel 251 of the test head 25 to connect with the pipe 53 of the piston tube 5.

[0044] Furthermore, the cylinder 3 is connected to the base surface via a bracket 7 .

[0045] In the initial state, the cylinder 3 is in a retracted state, and there is a certain distance between the test head 25 and the test station 4, which is convenient for placing the piston tube 5 on the positioning part.

[0046] When a blockage test is required, the cylinder 3 performs telescopic movement, pushes the connecting plate 26 to drive the test head 25 to move toward the test station 4 until the test head 25 abuts against the piston tube 5 and the test channel 251 is connected to the pipeline 53. Then, the blockage test is performed.

[0047] After the test is completed, the cylinder 3 drives the test head 25 to return to the initial position and wait for the next test.

[0048] As an optional implementation, the test heads 25 are arranged side by side on the connecting plate 26 , and the positioning portions are arranged in a one-to-one correspondence with the test heads 25 .

[0049] This arrangement enables multiple test heads 25 to work simultaneously, thereby achieving simultaneous testing of multiple piston tubes 5 and pipelines 53, effectively reducing test time and improving test efficiency.

[0050] As an optional implementation, the positioning portion includes a first positioning groove 41 and a second positioning groove 42, the first positioning groove 41 is adapted to the base 51 of the piston tube 5, the second positioning groove 42 is connected to the first positioning groove 41 and adapted to the tube body 52 of the piston tube 5, and the second positioning groove 42 is arranged close to the cylinder 3.

[0051] The first positioning groove 41 is used to fix and limit the base 51 of the piston tube 5 to prevent the piston tube 5 from shifting during the test, thereby improving the test stability and reliability.

[0052] The second positioning groove 42 is used to fix the tube body 52 of the piston tube 5 so that the tube body 52 can be precisely docked with the test head 25 , that is, the pipeline 53 is precisely connected with the test channel 251 .
