One-way valve structures can both obtain similar effect with reference to traditional various structures.
Its working principle and process are following:
1) goes journey working state (valve rod of multifunction valve is the whole example that is)
See Figure 13; The valve rod of handling selector valve 20 moves right (valve rod 3 of solenoid valve 4 promotion multifunction valves moves simultaneously) to the right, make the middle import 20.2a and a left side mouthful 20.1b connection that handle selector valve 20, and right mouthful 20.3b and right refluxing opening 20.3a is communicated with; The fluid in working medium source is through the intermediate flow channel 30.2 of collecting plate 30 like this; Successively through middle import 20.2a, get into the left chamber 40.1 of piston cylinder 40 by a left side mouthful 20.1b, the working medium fluids pass through right refluxing opening 20.3a again through right mouthful 20.3b in the right chamber 40.2 of piston cylinder 40 again; Through one-way valve 50, enter into the right runner 30.3 of collecting plate 30;
Move to the right because solenoid valve 4 promotes valve rod 3, the right import 1.3a of multifunction valve and right outlet 1.3b are communicated with, left import 1.1a and left side outlet 1.1b are communicated with; Like this; The working medium fluid is discharged with right outlet 1.3b through the right import 1.3a of multifunction valve successively in the right runner 30.3 of collecting plate 30, because the bore of these several passages is all bigger, flow is big relatively; Therefore the fluid of pressure medium enters into the piston cylinder chamber with fast speeds, the piston rapid movement;
See Figure 14, when piston motion to position shown in Figure 14 during promptly near the top of piston cylinder, the valve rod 3 that solenoid valve 4 promotes multifunction valves move (generally being to start through many modes always such as time control or Stroke Control) left; Make the right import 1.3a and right its direct connection of outlet 1.3b blocking-up of multifunction valve; Right import 1.3a also need pass through damping flow channel 1.7 and be communicated with right outlet 1.3b, because the bore of damping flow channel 1.7 is little through valve pocket 2; Resistance is big; Therefore the fluid of pressure medium can not be discharged from the piston cylinder chamber through multifunction valve with fast speeds, has increased the resistance to motion of piston, thereby has slowed down the movement rate of piston; Make piston touch the top of piston cylinder lentamente; To the gouging abrasion of piston, effectively prolong the working life of piston cylinder when having avoided piston to move rapidly, guaranteed the safety in operation and the stability of piston cylinder simultaneously;
2) backhaul working state (valve rod of multifunction valve is that non-integral is an example)
See Figure 15; The valve rod of handling selector valve 20 make the middle import 20.2a and right mouthful of 20.3b connection that handle selector valve 20, and a left side mouthful 20.1b and left refluxing opening 20.1a is communicated with to left movement (the left valve rod 3.a of solenoid valve 4 promotion multifunction valves outwards moves simultaneously); The fluid in working medium source is through the intermediate flow channel 30.2 of collecting plate 30 like this; Get into the right chamber 40.2 of piston cylinder 40 more successively through middle import 20.2a, right mouthful 20.3b, the working medium fluid passes through left refluxing opening 20.1a again through a left side mouthful 20.1b in the left chamber 40.1 of piston cylinder 40; Through one-way valve 50, enter into the left runner 30.1 of collecting plate 30;
Because promoting left valve rod 3.a, solenoid valve 4 moves left; The left import 1.1a of multifunction valve is communicated with left side outlet 1.1b, and like this, the working medium fluid is discharged with left side outlet 1.1b through the left import 1.1a of multifunction valve successively in the left runner 30.1 of collecting plate 30; Because the bore of these several passages is all bigger; Flow is big relatively, so the fluid of pressure medium enters into the piston cylinder chamber with fast speeds, the piston rapid movement;
