Have employed technique scheme, the beneficial effects of the utility model are: spool stress balance, and resistance to motion is little, can realize large discharge, respond fast; Improve sealing effect while the inclination angle of spool and valve body junction tapering surface not etc. guarantees spool stress balance, the leakage that sealing surface uneven wear causes can be avoided; Wear-resisting steel loop is arranged on making contact face, can slow down the wearing and tearing of part, increase the service life; Arranging of pad can accurate adjustment stroke, because sealing surface adopts line contact sealing, sealing strip area is close to zero, the imbalance of hydraulic pressure can not be caused, therefore this valve not only can realize import high pressure, the control of the hydraulic oil of outlet low pressure, also can be used for import high pressure, the control of the hydraulic oil of outlet high pressure.
accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the A portion structure for amplifying schematic diagram of Fig. 1.
embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, the spool 2 that hydraulic pressure large discharge high-speed figure valve open in usual comprises valve body 1 and is slidably mounted in described valve body, described spool 2 is column structure, the rear end of spool 2 is set with columned moving armature 5, the electromagnet assembly determining armature 3 and electromagnetic coil formation is installed in the valve body at described moving armature 5 rear, describedly determine to be provided with spring 6 between armature 3 and spool 2, the center of spool 2 is provided with pre-and post perforative through hole 21, described valve body is provided with liquid entering hole 8 and liquid outlet 9, described liquid entering hole 8 is arranged around spool 2, described liquid outlet 9 is positioned at one end of valve body, be positioned on the axis of spool 2.When valve open, liquid enters the inner chamber of valve body by liquid entering hole 8, then is discharged by liquid outlet 9, and the liquid of spool 2 front end can import in the cavity of spool 2 rear end by through hole 21, makes spool 2 stress balance, reduces its running resistance, improves speed of response.
The boss 11 around spool 2 is provided with in the inner chamber of described valve body 1.As shown in Figure 2, the front end of described boss 11 is provided with the inner conical surface 34 of interior chamfering shape, described spool 2 is provided with the dashpot 31 of the annular being communicated with liquid entering hole 8, and the front end of described dashpot 31 is provided with the male cone (strobilus masculinus) 25 of coupling inner conical surface 34, and the inclination angle G of described inner conical surface 34 is greater than the inclination angle H of male cone (strobilus masculinus) 25.
When spool 2 moves to rear end, valve closing time, male cone (strobilus masculinus) 25 mates to be formed with inner conical surface 34 and seals, due to two conical surfaces inclination angle not etc., sealing herein by inner conical surface 34 the knuckle of inner side be resisted against on male cone (strobilus masculinus) 25 and formed, it is the sealing that annular wire and conical surface are formed, have and process feature that is simple, good sealing effect, and, because the area of contact of linear sealing is close to zero, when spool closed condition, the pressure of hydraulic oil to the active force that spool produces to make a concerted effort be zero, make valve realize high-speed response.
Be provided with gap between described moving armature 5 and the inwall of valve body, described spool 2 is provided with pressure compensation opening 23, and described pressure compensation opening 23 is communicated with the inner chamber of spool 2 and the gap between moving armature 22 and valve body.The liquid in through hole 21 can be made like this to be full of whole body cavity, to make spool 2 and moving armature 5 stress balance, reduce resistance to motion, improve speed of response.
In addition, described front end of determining armature 3 is provided with spring mounting hole, is provided with rear wear-resisting steel bushing 61 in described spring mounting hole, is provided with front wear-resisting steel bushing 24 in the inner chamber of described moving armature 5, and described spring 5 is arranged in front wear-resisting steel bushing 24 and rear wear-resisting steel bushing 61.The front end of described moving armature 5 is provided with the mounting hole of coupling spool 2, and the bottom of described mounting hole is provided with pad 71, and described spool 2 is fixedly inserted in described mounting hole; The front-end face of moving armature 5 is installed with the wear-resisting steel loop 7 around spool 2.By adjusting the thickness of pad 71, the sealing of spool can be finely tuned, to reach optimal seal state.
In the process that moving armature 5 moves with movable valve plug 2, wear-resisting steel loop 7 collides the rear end of boss 11, plays spacing effect.Meanwhile, front wear-resisting steel bushing 24 plays with rear wear-resisting steel bushing 61 effect protecting spring 5.This three places High Strength Wear-Resistance Material can slow down the wearing and tearing of part, increases the service life.
The present embodiment is open type valve, and time electromagnetic coil 4 is idle, spool 2 is pushed to front end by the elastic force of spring 5, and liquid can enter liquid outlet 9 by liquid entering hole 8, and valve is in open mode.Otherwise produce magnetic force when electromagnetic coil 4 obtains electric, the spring band movable valve plug 2 that moving armature 5 overcomes spring 6 under magnetic force moves backward, and male cone (strobilus masculinus) 25 and inner conical surface 34 are formed and seal, and fluid passage is truncated, and valve is in closed condition.
