[0015] (3) Beneficial effects

[0016] The utility model provides a valve testing machine test data acquisition device, which has the following beneficial effects:

[0017] 1. The valve testing machine test data acquisition device transports the hydraulic oil in the oil tank to the valve testing host through the oil outlet pipe and the oil inlet pipe, so as to perform pressure testing on the valve. During the oil transportation process, the filter in the filter box filters the impurities contained in the hydraulic oil. When there are too many impurities on the surface of the filter, the motor is started. Through the cooperation of the rotating column and the rotating groove, the cleaning brush can be driven to move up and down at both ends of the cleaning plate to clean the impurities on the surface of the filter. When the cleaning brush moves downward, it can drive the connecting rod to move downward. Due to the cooperation of the pressure column and the trapezoidal baffle, the impurities are swept into the collection box, thereby avoiding impurities filtering and clogging the filter, thereby affecting the filtering effect of the filter, thereby improving the accuracy of the results of the valve testing machine.

[0018] 2. The valve testing machine tests the data acquisition device. When the pressure sensor needs to be replaced, the pressure sensor is pressed to drive the connecting plate to move downward. Through the cooperation of the sliding column and the sliding groove, the sliding column can be separated from the limit of the fixed plate, so that the pressure sensor can be removed. After replacing the new pressure sensor, due to the cooperation of the second spring, the sliding column can be re-fixed in the depression of the sliding groove, so that the pressure sensor can be fixed, which facilitates the replacement of the pressure sensor.
