Embodiment
For further disclosing technological scheme of the present invention; Specify mode of execution of the present invention below in conjunction with accompanying drawing: like Fig. 1 and shown in Figure 4; A kind of pneumatic arrangements for speed regulation comprise speed governing solenoid valve 2,3,4, and control system is connected with speed governing solenoid valve 2,3,4 respectively with execution cylinder 5; One end of speed governing solenoid valve 2,3,4 is connected with source of the gas; Form gas circuit, on the gas circuit main line, be connected with the first gas circuit branch road 6, the second gas circuit branch road 7, the 3rd gas circuit branch road 8 side by side, every branch road respectively with carry out cylinder 5 and be connected.On the gas circuit main line, be connected with reduction valve 1, an end of reduction valve 1 is connected with source of the gas.On every gas circuit branch road, be connected with throttle valve 9 respectively, regulate the gas circuit gas flow, throttle valve 9 is connected with reduction valve 1.
When the speed governing solenoid valve 2 of the first gas circuit branch road 6 led to: gas flow was a;
When the speed governing solenoid valve 3 of the second gas circuit branch road 7 led to: gas flow was b;
When the speed governing solenoid valve 4 of the 3rd gas circuit branch road 8 led to: gas flow was c.
As shown in Figure 1: when pneumatic movement begins, by control system control speed governing solenoid valve 2,3,4 standard-sized sheets, carry out cylinder 5 and obtain maximum flow, actuator moves with top speed;
Getting into the total discharge of carrying out cylinder 5 gases is a+b+c.
As shown in Figure 2: in the pneumatic movement process, opened by control system control speed governing solenoid valve 2,3, speed governing solenoid valve 4 cuts out, and carries out cylinder 5 flows and reduces actuator's retarded motion;
The total discharge that gets into cylinder gas is a+b.
As shown in Figure 3: at pneumatic movement last (soon near exercise end); Open by control system control speed governing solenoid valve 2; Speed governing solenoid valve 3,4 cuts out, and carries out cylinder and obtains minimum discharge, and actuator moves with minimum speed; Thereby the assurance accurate positioning can not make actuator overshoot position because of the inertia that speed produces too soon;
The total discharge that gets into cylinder gas is a.
The present invention is divided into plurality of sections through on the gas circuit main line, connecting side by side some branch roads with movement locus, and every section moves through control system and gives and carry out solenoid valve with different flows, thereby realizes good speed controlling.The present invention is simple in structure, and is easy to operate, and accurate positioning has improved working efficiency greatly, has reduced cost of production, has guaranteed the quality of product.
More than, basic design of the present invention and basic principle have been set forth through introduction to listed mode of execution.But the present invention never is limited to above-mentioned listed mode of execution, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on technological scheme of the present invention of change all should belong to protection scope of the present invention.
