The horizontal movement of the festo rodless cylinder DGC-K-63-200-PPV-A-GK is achieved by the photoelectric switch (2), the pressure reducing valve, and the control circuit. The positioning post (4) connected to the positioning air filter (3) performs extension and retraction movements under the control of the two-position three-way valve and the rodless air filter return control of the pneumatic two-position five-way valve. The initial position of the device is the original position after the compressed air enters the air filter. When the next positioning is performed, the control circuit first sends a signal to the pressure reducing valve, which switches direction, controlling the rodless air filter to move forward. When the rodless air filter moves forward a certain distance, it triggers the two-position three-way valve to switch the two-position five-way pneumatic control valve, causing the positioning air filter positioning post (4) to extend. The rodless air filter moves forward until the positioning post (4) hits the positioning stop block (9), completing the positioning of the second station. After the second station is positioned, other stations perform their actions. After the actions are completed, a signal is given to perform the next positioning. At this point, the pressure reducing valve is controlled to switch direction by the control signal from the printing mechanism, causing the rodless air control filter to retract a short distance. During the short retraction, the compressed air controlling the rodless air filter retraction also causes the two-position five-way pneumatic control valve to switch direction, causing the positioning air filter positioning post (4) to retract. 9. Flexible connection of the pipeline can be achieved with the flexible groove-type clamp connection, forming a flexible system that can absorb the length displacement of the pipe caused by temperature changes and allows for a certain angle of pipe偏移. ② The pressure sensor is a type of volume flow measurement instrument. During the measurement process, it is not affected by the temperature, viscosity, density, and electrical conductivity (within a certain range) of the measured medium. Therefore, after calibration with water, the electromagnetic flowmeter can be used to measure the flow of other conductive liquids without needing additional corrections. 1. Use a dial indicator to measure the bending values at various parts of the valve rod, and make marks and records to determine the highest and lowest points of bending. Notes on valve islands: There are two types of valve islands, normally closed and normally open. The normally closed type is in a closed state when power is off. When the coil is energized, electromagnetic force is generated, causing the moving iron core to overcome the spring force and directly open the valve, allowing the medium to pass through; when the coil is de-energized, the electromagnetic force disappears, and the moving iron core returns to its original position under the action of the spring force, directly closing the valve port, and the medium does not pass through. The structure is simple, the action is reliable, and it works normally under zero pressure difference and micro vacuum. The normally open type is exactly the opposite. It uses a primary valve opening and a secondary valve opening connected together, with the main valve and the pilot valve opening step by step under the direct action of electromagnetic force and pressure difference. When the coil is energized, electromagnetic force is generated causing the moving iron core and the stationary iron core to attract each other, opening the pilot valve port, which is located on the main valve port, and the moving iron core is connected with the main valve core. At this point, the pressure in the upper chamber of the main valve is relieved through the pilot valve port, and under the combined action of the pressure difference and the electromagnetic force, the main valve core moves upward, opening the main valve for medium flow. When the coil is de-energized, the electromagnetic force disappears, and at this point, the moving iron core closes the pilot valve port under the action of its own weight and spring force. At this point, the medium enters the upper chamber of the main valve core through the balance hole, causing the pressure in the upper chamber to increase. At this point, under the action of spring return and pressure, the main valve closes, causing the medium to stop flowing. The structure is reasonable, the action is reliable, and it works reliably even at zero pressure difference. The universal valve island itself has an internal structure with an air buffer of about 10 mm. The universal valve island in
