Embodiment
Below in conjunction with Figure of description, the utility model will be further described, but the utility model protection domain is not limited in this:
As shown in Figure 1, a kind of Novel diversion valve arrangement described in the utility model, comprise shunting valve body 1 and be arranged on the diverter valve assembly 2 in shunting valve body 1, steering knuckle assembly 3, turn to safety valve 4 and main safety valve 5, described diverter valve assembly 2 comprises flow divider valve core 11, flow divider valve core 11 one end arranges shunting spring 12, the other end arranges and can prevent from turning to the unidirectional damping assembly turning to pause with mechanism's teamwork generation, described unidirectional damping assembly comprises Returnning spring 16, damping steel ball 15 and damping plug screw 14, Returnning spring 16 is arranged between damping plug screw 14 and flow divider valve core 11 right-hand member, damping steel ball 15 is between Returnning spring 16 and damping plug screw 14, damping plug screw 14 is arranged damping hole 13, steering knuckle assembly 3 comprises valve seat, joint and turns to steel ball, described valve seat touches with shunting spring 12 and is connected, the described steel ball that turns to is arranged between joint and valve seat, described shunting spring 12 is arranged between the valve seat of steering knuckle assembly 3 and flow divider valve core 11 left end, oil inlet P 6 be set, turn to a mouthful PF7 in shunting valve body 1, guide's oil duct N8, work oil duct EF 9, back oil road T10, restriction X17 and restriction X118.
As shown in Figures 2 and 3, during meta, flow divider valve core 11 is toward moving left, fluid is except supply turns to mouthful PF7, and other fluid remove work oil duct EF 9, and now the pressure of oil inlet P 6 is for pushing flow divider valve core 11 open, oil inlet P 6 is connected with work oil duct EF 9, overcomes the pressure of shunting spring 12;
1-shunts valve body, 2-diverter valve assembly, 3-steering knuckle assembly, 4-turns to safety valve, 5-main safety valve, 6-oil inlet P, 7-turns to mouthful PF, 8-guide oil duct N, a 9-work oil duct EF, 10-back oil road T, 11-flow divider valve core, 12-shunts spring, 13-damping hole, 14-damping plug screw, 15-steel ball, 16-Returnning spring, 17-restriction X, 18-restriction X1.
When institution staff or when turning to separately, oil inlet P 6 pressure is by load feedback, and pressure oil enters guide's oil duct N 8 by restriction X 17 and damping hole 13, promotes flow divider valve core 11 to left movement, due to the existence of damping function, certain reflecting time is had to make action mild.
As shown in Figure 3, Figure 4, when mechanism action with when turning to joint operation, oil inlet P 6 feeds back the higher person pressure.Mouthful PF 7 pressure that turns to of steering procedure is generally below 7MPa, and during institution staff, work oil duct EF 9 pressure can reach more than 10MPa when heavy duty, reaches main safety valve 5 pressure when building the pressure.Therefore, during teamwork, it is a kind of transient equiliblium that oil inlet P 6 pressure is generally greater than 10MPa flow divider valve core, pressure due to guide's oil duct N 8 equals to turn to the pressure of mouthful PF 7 and the pressure sum shunting spring 11, therefore when building the pressure, the pressure of oil inlet P 6 is far longer than the pressure of guide's oil pocket N 8, this pressure difference is moved to left by flow divider valve core 11, and the size controlling throttle orifice X 17 realizes.
When the moment of mechanism's tenth skill, what feed back due to oil inlet P 6 is the pressure of work oil duct EF 9, and therefore at the pressure (being less than 1MPa) that produces to meta crushing of abrupt pressure reduction of this oil inlet P 6, two ends pressure reduction reduces instantaneously moment.Now to open damping steel ball 15 fuel-displaced for the fluid of guide's oil pocket N 8, flow divider valve core 11 is under the effect of shunting spring 12, be rapidly to and move right, reduce the size of restriction X1 18, re-establish pressure, make the time of adjustment be less than person's development detecting period, steering operation gets up to feel smooth and easy, does not occur the even reversal phenomenon that pauses.
