Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
The driving cylinder beneficial to improving the air tightness and the maneuverability as shown in fig. 1 comprises a cylinder body 1 and an air supply system, wherein a piston 2 is arranged in the cylinder body 1 in a sliding manner, and the piston 2 is connected with a piston rod 3; the air supply system comprises a pneumatic triple piece 4, a two-position five-way reversing valve 5 and an air source 6.
The air source 6 is connected with the air inlet end of the pneumatic triple piece 4, the air outlet end of the pneumatic triple piece 4 is connected with the air inlet end of the two-position five-way reversing valve 5, and a quick exhaust valve 9 and a ball valve 10 are respectively arranged between the two-position five-way reversing valve 5 and the rod cavity 7 and the rodless cavity 8 of the cylinder body 1.
The periphery of the cylinder block 1 is coated with a water tank sleeve 11, the water tank sleeve 11 positioned at the bottom of the cylinder block 1 is connected with a water inlet pipe 12 for introducing cooling water, the water tank sleeve 11 positioned at the top of the cylinder block 1 is connected with a water outlet pipe 13, and water valves are arranged on pipelines of the water inlet pipe 12 and the water outlet pipe 13.
After the air supply of the air source 6 is filtered and pressure-regulated by the pneumatic triple piece 4, the clean air source 6 enters the two-position five-way reversing valve 5, the direction of the air source 6 is controlled by the two-position five-way reversing valve 5, the controlled air source 6 enters the quick exhaust valve 9 from the port B of the two-position five-way reversing valve 5, the quick exhaust valve 9 enters the rodless cavity 8 of the cylinder, the air source 6 pushes the piston 2 to extend upwards after entering the rodless cavity 8 of the cylinder, the air on one side of the rod cavity 7 of the cylinder is discharged out of the cylinder along with the pushing of the piston 2 to enter the quick exhaust valve 9, and the air is directly discharged from the port R of the quick exhaust valve 9.
