Below in conjunction with Figure of description, the utility model is further elaborated.
As shown in Figure 1, the utility model is used for the spring hydraulic stored energy mechanism of the automatic divide-shut brake powder operation device of primary cut-out, there is working cylinder 1 (structure is as shown in Fig. 2 A ~ 2D), loaded cylinder 8 and butterfly spring 13, wherein loaded cylinder 8 is sleeved in the middle part of the external diameter of working cylinder 1, butterfly spring 13 is set in the external diameter bottom of loaded cylinder 8 outside and working cylinder 1, and the upper surface of butterfly spring 13 is pressed on by positioning wire in the groove of the large circle end face of loaded cylinder 8; The middle part cylindrical of working cylinder 1 is set with from inside to outside the 2nd O RunddichtringO back-up ring the 9, the 3rd O RunddichtringO (115 × 3.55) 10 and sealing ring baffle ring 12, microcephaly's cylindrical of sealing ring baffle ring 12 is set with porose right-angle array sealing ring (KNP613-140) 11, from being separately installed with the 3rd O RunddichtringO back-up ring the 17, the 4th O RunddichtringO (110 × 5.3) 16, second guidance tape (346 × 5 × 2.5) 15 and axle right-angle array sealing ring (KNR611-110) 14 outside to inside in microcephaly's inner hole groove of loaded cylinder 8; Be provided with inside loaded cylinder major part on the first guidance tape (445 × 5 × 2.5) 7, end face and have the 2nd O RunddichtringO (145 × 3.55) 5, O RunddichtringO back-up ring the 2, an one O RunddichtringO (140 × 5.3) 3 is installed in the internal bore groove of energy storage cylinder cap 4; Energy storage cylinder cap 4 is fixed in the big end surface of loaded cylinder 8 with six hexagon socket cap head screws (M8 × 25) 6.
As shown in Fig. 2 A, 2B, the present embodiment is provided with oil return groove 21 at working cylinder 1 cylindrical 140 diameter apart from end face 5mm place, be provided with each radial spill port 20 of multiple radial spill port 20 (this example three) in groove to be communicated with corresponding axial spill port 19 respectively, axial spill port 19 is communicated with fuel tank; The middle part of working cylinder 1 is provided with the external screw thread M115 × 1-6H for installing sealing ring baffle ring 12.
As shown in Fig. 4 A, 4B, loaded cylinder 8 is provided with multiple spill port, and the present embodiment is three, i.e. the first ~ three spill port 8a ~ 8c, be distributed on loaded cylinder 8 wall, the upper end outlet of spill port is at distance end face 10mm place, and the lower end outlet of spill port is at distance 10mm place, lower surface; Hydraulic oil in loaded cylinder 8 may have micro-leakage, and the fluid of leakage flows back to fuel tank by this hole.As shown in Fig. 5 A, 5B, microcephaly's cylindrical of sealing ring baffle ring 12 is set with porose right-angle array sealing ring 11.
As shown in Figure 1, when hydraulic system does not work, loaded cylinder 8 is under the effect of butterfly spring 13 for operation principle of the present utility model, and in it, hole end surface is close in the big end surface of sealing ring baffle ring 12, both non operating state.When system after operation of oil pump forms injection pressure oil in space (maximum pressure 70MPa) by turnover oilhole to the cylindrical shoulder of loaded cylinder 8 endoporus shoulder and working cylinder 1, under pressure oil effect, the cylindrical spatial volume that shoulder is formed of loaded cylinder 8 endoporus shoulder and working cylinder 1 increases gradually, loaded cylinder 8 moves down, butterfly spring 13 is gradually reduced simultaneously, when moving to setting height, travel switch disconnects, motor power disconnects, oil pump quits work, loaded cylinder 13 is in packing state, now the elastic force of butterfly spring 13 acts on loaded cylinder 8, namely the active force of butterfly spring 13 act on the cylindrical shoulder of loaded cylinder 8 endoporus shoulder and working cylinder 1 form in space fluid on, the size of butterfly spring 13 active force determines the pressure size of loaded cylinder 8 inner fluid.When system to be received point or system oil-way break-in at once after reclosing command, the valve port closing turnover oilhole is opened, and the fluid in loaded cylinder 8, under the effect of butterfly spring 13, is extruded at once, and complete needed for flowing to point or closing position.During separating brake, fluid enters the epicoele of working cylinder 1 under the control of reversal valve, promotes piston and moves down.During combined floodgate, fluid carries out the cavity of resorption of working cylinder under the control of reversal valve, promotes piston moves.After fluid in loaded cylinder 8 is extruded, loaded cylinder 8 is upspring, and connect with the travel switch of its movement simultaneously, motor is powered, and drive oil pump to continue to oiling in loaded cylinder 8, when reaching predetermined altitude, travel switch disconnects, and motor quits work, oil pump fuel cut-off.
Seal with hole right-angle array sealing ring (KNP613-140) 11 between the large nose end of loaded cylinder 8 and the large cylindrical of working cylinder 1, in order to ensure sealing and not damage hole right-angle array sealing ring 11, have employed split type groove, increase sealing ring baffle ring 12, the connection of sealing ring baffle ring 12 and working cylinder 1 is for being threaded, in order to prevent threaded connection place from leaking, be provided with the 2nd O RunddichtringO back-up ring the 9, the 3rd O RunddichtringO (115 × 3.55) 10 at microcephaly's endoporus of sealing ring baffle ring 12 and the cylindrical place of working cylinder 1.
In the microcephaly inner side of loaded cylinder, axle right-angle array sealing ring (KNR611-110) 14 is set, in order to the phase mutual friction of the outer surface of the inner surface and working cylinder 1 that reduce loaded cylinder 8, in the major part of loaded cylinder, bore ends and microcephaly's endoporus centre position are provided with the first guidance tape (445 × 5 × 2.5) 7 and the second guidance tape (346 × 5 × 2.5) 15 respectively.
Because loaded cylinder 8 inner fluid pressure is comparatively large, upper hole right-angle array sealing ring 11 and bottom axle right-angle array sealing ring 14 liang of places, may have the oil liquid leakage of trace.In order to not make oil liquid leakage to the outside of body, outside microcephaly's endoporus of loaded cylinder 8, the 4th O RunddichtringO the 16, three O RunddichtringO back-up ring 17 and an O RunddichtringO 3, an O RunddichtringO back-up ring 2 are set respectively with energy storage inner hole of cylinder cover.In order to the fluid of leakage is flow back to fuel tank, uniform 3 place's spill ports in the cylinder arm of loaded cylinder 8.
On working cylinder 1, assigned position place more than hole right-angle array sealing ring is provided with groove, multiple radial hole 20 is provided with in groove, with each radial hole 20 to there being working cylinder spill port 19 (this spill port is for axial), the present embodiment is three, when butterfly spring 13 is compressed to required height, the upper port of the first ~ three loaded cylinder spill port 8a ~ 8c corresponding on loaded cylinder is communicated with three working cylinder spill ports 19 by ring-shaped groove, and spill port is communicated with fuel tank; Leak fluid and just can get back to fuel tank, this addresses the problem the problem that fluid trace leaks outside.
