Embodiment 3
As shown in Figure 3, a kind of combination brake switch and proporting or valve island, it comprises the multifunction valve 10 in embodiment 1 or 2, and concrete structure is shown in description in embodiment 1, no longer repeats here to describe;
Three manipulation selector valves 20;
And a collecting plate 30;
Make the left mouth 20.1b of manipulation selector valve 20 1 side, left chamber 40.1, right chamber 40.2 that right mouth 20.3b connects piston cylinder 40 respectively, and handle left refluxing opening 20.1a, the central inlet 20.2a of selector valve 20 another side and right refluxing opening 20.3a and connect the left runner 30.1 of collecting plate 30, intermediate flow channel 30.2 and right runner 30.3 respectively;
Left import 1.1a, the central inlet 1.2a of multifunction valve 10 and right import 1.3a connect the left runner 30.1 of collecting plate 30, intermediate flow channel 30.2 and right runner 30.3 respectively;
Collecting plate 30 intermediate flow channel 30.2 connects working medium source, and other runner hole sealing covers of its both ends of the surface are blocked;
Three manipulation selector valves 20 can connect three piston cylinders respectively, control each piston cylinder and carry out work, see Fig. 4.
Its working principle and process as follows:
1) journey working state (valve rod of multifunction valve is overall is example) is gone
See Fig. 4, the valve rod handling selector valve 20 moves right (solenoid valve 4 promotes valve rod 3 action to the right of multifunction valve simultaneously), the central inlet 20.2a of manipulation selector valve 20 is communicated with left mouth 20.1b, and right mouth 20.3b is communicated with right refluxing opening 20.3a, the fluid in such working medium source passes through the intermediate flow channel 30.2 of collecting plate 30, again successively through central inlet 20.2a, left mouth 20.1b enters the left chamber 40.1 of piston cylinder 40, in the right chamber 40.2 of piston cylinder 40, working medium fluid is through right mouth 20.3b, again through right refluxing opening 20.3a, enter into the right runner 30.3 of collecting plate 30,
Because solenoid valve 4 promotes valve rod 3 action to the right, the right import 1.3a of multifunction valve is communicated with right outlet 1.3b, left import 1.1a is communicated with left outlet 1.1b, like this, in the right runner 30.3 of collecting plate 30, working medium fluid is discharged through the right import 1.3a of multifunction valve and right outlet 1.3b successively, and because the bore of this several passage is all comparatively large, flow is relatively large, therefore the fluid of pressure medium enters into piston cylinder chamber, piston rapid movement with speed faster;
See Fig. 5-6, when the top of position shown in piston movement to Fig. 5 namely close to piston cylinder, solenoid valve 4 promotes valve rod 3 action left (being generally started by time controling or Stroke Control) of multifunction valve, make the right import 1.3a of multifunction valve block it with right outlet 1.3b to be directly communicated with, left import 1.1a blocks it with left outlet 1.1b and is directly communicated with, right import 1.3a is by valve pocket 2, also need to be communicated with right outlet 1.3b through throttle valve 1.7, because the bore of throttle valve 1.7 is little, resistance is large, therefore the fluid of pressure medium can not be discharged through multifunction valve from piston cylinder chamber with speed faster, add the resistance to motion of piston, thus slow down the movement rate of piston, piston is made to touch the top of piston cylinder lentamente, gouging abrasion to piston when avoiding piston jerky motion, effectively extend the working life of piston cylinder, ensure that safety in operation and the stability of piston cylinder simultaneously,
2) backhaul working state (valve rod of multifunction valve is non-integral is example)
See that Fig. 7 (eliminates collecting plate, its arrange be the same above), to left movement, (solenoid valve 4 promotes a left side for multifunction valve to the valve rod of manipulation selector valve 20 simultaneously, right valve rod 3 respectively left, right action), the central inlet 20.2a of manipulation selector valve 20 is communicated with right mouth 20.3b, and left mouth 20.1b is communicated with left refluxing opening 20.1a, the fluid in such working medium source passes through the intermediate flow channel 30.2 of collecting plate 30, again successively through central inlet 20.2a, right mouth 20.3b enters the right chamber 40.2 of piston cylinder 40, in the left chamber 40.1 of piston cylinder 40, working medium fluid is through left mouth 20.1b, again through left refluxing opening 20.1a, enter into the left runner 30.1 of collecting plate 30,
Because solenoid valve 4 promotes left valve rod 3.a action left, right valve rod 3.b action to the right, the right import 1.3a of multifunction valve is communicated with right outlet 1.3b, left import 1.1a is communicated with left outlet 1.1b, like this, in the left runner 30.1 of collecting plate 30, working medium fluid is discharged through the left import 1.1a of multifunction valve and left outlet 1.1b successively, because the bore of this several passage is all larger, flow is relatively large, therefore the fluid of pressure medium enters into piston cylinder chamber, piston rapid movement with speed faster;
See Fig. 8-9, when the top of position shown in piston movement to Fig. 8 namely close to piston cylinder, solenoid valve 4 promotes the left valve rod 3.a action to the right (being generally started by time controling or Stroke Control or other control) of multifunction valve, make the left import 1.1a of multifunction valve block it with left outlet 1.1b to be directly communicated with, left import 1.1a is by valve pocket 2, also need to be communicated with left outlet 1.1b through throttle valve 1.6, because the bore of throttle valve 1.6 is little, resistance is large, therefore the fluid of pressure medium can not be discharged through multifunction valve from piston cylinder chamber with speed faster, add the resistance to motion of piston, thus slow down the movement rate of piston, piston is made to touch the top of piston cylinder lentamente, gouging abrasion to piston when avoiding piston jerky motion, effectively extend the working life of piston cylinder, ensure that safety in operation and the stability of piston cylinder simultaneously.
