An air inlet of the throttle valve 3 is connected with a port C of the two-position three-way single electric control normally open electromagnetic valve 2 through a pipeline; the throttle valve 3 may be a valve available from Ningbo hundred million days technologies Inc. under model number ESA 12. The throttle valve 3 throttles the compressed air in an exhaust backflow mode, adjusts the flow rate of the compressed air within the adjusting range of 2-5mm/s, so that the moving speed of the air cylinder 5 is very low, and the air cylinder 5 is very easy to position under the condition that the moving speed is low, so that the problem of expansion of the air cylinder 5 is solved, and the operating speed of the air cylinder 5 can be better adjusted. The pipeline all is provided with one-way throttle valve 7 with the interface connection department of cylinder 5, and concrete can use the mode of exhaust throttle to control, adopts the exhaust throttle after, and two tee bend single automatically controlled normally open solenoid valve 2 commutate back, and choke valve 3 opens, aerifys to cylinder 5 rodless chamber fast, and the gas in rodless chamber can only be through the one-way throttle valve 7 exhaust of exhaust side. By adjusting the opening speed of the throttle valve 3, the moving speed of the cylinder can be changed. The control mode has the advantages that the piston runs stably, and the speed control is accurate. The throttle valve 3 is a pipeline type throttle valve, so that the throttle valve can be better installed with a pipeline.
The port A of the three-position five-way middle seal electromagnetic valve 4 is respectively connected with the port B of the two-position three-way single electric control normally open electromagnetic valve 2 and the air outlet of the throttle valve 3 through a pipeline and a three-way joint 6; the three-position five-way middle sealing electromagnetic valve 4 can be a valve with model number SY9320-5DZ-03 of SMC company.
A mouth and the B mouth of cylinder 5 pass through the pipeline and are connected with the C mouth and the B mouth of three-position five-way middle seal solenoid valve 4 respectively, can touch proximity switch's response end when cylinder 5 moves, and when proximity switch sensed cylinder 5, two tee bend list automatically controlled normally open solenoid valve 2 got the electricity switching-over and made its A mouth and C mouth switch on.
