Detailed description of the invention
Two grades of reversing arrangements of this hydraulic actuating mechanism band complex function include main valve body 1, left signal chamber 2, left valve seat 3, left valve rod 4, screw plug 5, separating brake one-step valve 6, sealing ring 7, runner 8, low pressure chamber 9, right valve rod 10, signal switching chamber 11, M signal chamber 12, high pressure chest 13, right valve seat 14, screw 15, spring 16, cap 17, sealing ring 18, circumferential weld 19, right signal chamber 20, screw plug 21, throttle orifice 22, screw 23, runner 24, runner 25, runner 26, restriction 27, runner 28, combined floodgate one-step valve 29, runner 30 and runner 31.Separating brake one-step valve 6, combined floodgate one-step valve 29 are arranged on the bottom surface of main valve body 1, the left side is the separating brake one-step valve 6 that two installation directions are consistent, the right is combined floodgate one-step valve 29, left valve seat 3 is arranged in main valve body 1 with right valve seat 14, left valve rod 4 is arranged on after combining with right valve rod 10 in the slideway of left valve seat 3 and the formation of right valve seat 14, four constitute two grades of reversing arrangements, right valve seat 14 forms normal high pressure chest 13 with main valve body 1 inner chamber, left valve seat 3 and main valve body 1 inner chamber form normal low pressure chamber 9, and left valve seat 3, right valve seat 14 and main valve body 1 inner chamber form signal switching chamber 11.Often the hydraulic oil of high pressure chest 13 enters the left signal chamber 2 of left valve seat 3 side by runner 8, and the most a part of hydraulic oil acts on M signal chamber 12.Being provided with the cap 17 of initial tension of spring on right valve seat 14, the rod end of right valve rod 10 is designed as concavo-convex header structure, and the structure centre of cap 17 is arranged symmetrically with.Right valve seat 10 designs restriction 27 and runner 28.
Described point, combined floodgate one-step valve 6,29 structure identical, be electromagnetic type 2/2-way reversal valve.Separating brake one-step valve 6 forward is installed on main valve body 1 bottom surface, and combined floodgate one-step valve 29 is reversely installed on main valve body 1 bottom surface, and normal high pressure chest 13 fluid is entered in combined floodgate one-step valve 29 by runner 31.When combined floodgate one-step valve 29 switches, hydraulic oil enters right signal chamber 20 by runner 26, runner 24, circumferential weld 19.Owing to the area sum in right signal chamber 20 with M signal chamber 12 is more than left signal chamber 2 area, thus left and right valve rod 4,10 is promoted to be moved to the left together.Opening valve port so that often high pressure chest 13 is connected with signal switching chamber 12, signal switching chamber 12 exports hydraulic oil.In like manner, when separating brake one-step valve 6 is connected, runner 28 is communicated with runner 30, make right signal chamber 20 inner high voltage oil by low pressure chamber 9, owing to left signal chamber 2 area is more than M signal chamber 12 area, promote left and right valve rod 4,10 to move right together.Normal low pressure chamber 9 is connected with signal switching chamber 12, and signal switching chamber 12 exports low pressure oil, thus completes the commutation function of two grades of reversing arrangements.
Described right valve seat 14 is provided with decompression and prevents slow separating device, be specifically made up of with cap 17 screw 15, spring 16.Right valve rod 10 right-hand member is designed with concave head structure, and cap 17 is pressed in the concave head of right valve rod 10 under the action of the spring 16.After in normal high pressure chest 13, pressure is reduced to certain value, right signal chamber 20 adds the difference in M signal chamber 12 and left signal chamber 2 and overcomes cap 17 to be pressed in the resistance that right valve rod 10 produces by not promoting, it is impossible to promote left and right valve rod 4,10 to be moved to the left together.Two grades of reversing arrangements only need to arrange less part, it is ensured that two grades of reversing arrangements are under decompression state, it is impossible to carries out slow point of operation.
Described safe self-locking function, by designing suitable restriction 27, runner 25 screw 23 on right valve seat 14, the oil in signal switching chamber 12 is by restriction 27, runner 25, in screw 23, restriction 22 enters right signal chamber 20, in maintaining right signal chamber 20 and signal switching chamber 12, pressure is the most consistent, has stopped because leakage, compression shock cause the possibility of two grades of reversing arrangement actions.Meanwhile, suitable restriction 27, restriction 22 can stop the pressure oscillation impact on right signal chamber 20 in signal switching chamber 12.
