Abstract
The utility model relates to an open and close procedure adjustable flow limiting electrical liquid reversal valve used for the hydraulic machinery equipment. The utility model is composed of an electromagnetic reversal valve, a dampener, a valve body, the valve core, a spring and an end cover, and besides, the utility model is characterized in that the limiting electrical liquid reversal valve is also provided with an adjusting device for the stroke of a valve core and an oil guiding shaft journal of the valve core, which is a cone or whose part is the cone. The utility model has the advantages that the running speed of an actuating device can be adjusted in order to adapt requirements of different technics when the hydraulic machinery equipment adopts the valve; the utility model has small noise and vibration.
Description
The utility model relates to the improvement of electro-hydraulic reversing valve.
Accompanying drawing 1 is the existing electro-hydraulic reversing valve partial sectional view that is used for hydraulic machinery equipment.With reference to Fig. 1, existing electro-hydraulic reversing valve is made up of solenoid directional control valve 1, damper 2, valve body 3, spool 4, spring 5 and end cap 6.It is not structurally owing to have spool stroke regulating device and spool Oil Guide axle journal.What adopt is cylindrical body, so there is following defective: the one, spool stroke is that fixed value can not be transferred; Turn to the no current limliting effect in back, the fluid flow is difficult to control, so actuator's motion speed can not be adjusted; The 2nd, rise sharply for the amount rapid drawdown, there is not the buffer function of progressively lifting, so noise is big, vibratility is big.
The purpose of this utility model is to provide a kind of can make the opening-closing process that actuator's motion speed is adjustable, noise is little, vibratility is little can debug Electro-hydraulic direction valve.
The utility model is to adopt to set up spool stroke controlling device and the spool Oil Guide axle journal be made up of guide pin bushing 7, resistance position bar 8 and handle thereof or handwheel adopt the mode of cone to achieve the goal on end cap 6.
Characteristics of the present utility model are: hydraulic machinery equipment adopts its actuator's motion speed of this valve to adjust; To adapt to the needs of different process; Noise is little, shakes little.
Below in conjunction with accompanying drawing embodiment is described:
Fig. 1 is existing electro-hydraulic reversing valve partial sectional view.
Fig. 2 is this Electro-hydraulic direction valve partial sectional view.
With reference to Fig. 1～2, this Electro-hydraulic direction valve is made up of solenoid directional control valve 1, damper 2, valve body 3, spool 4, spring 5, end cap 6 and spool stroke controlling device.The spool stroke controlling device is made up of guide pin bushing 7, resistance position bar 8 and handle or handwheel 9.End cap 6 is the wheel drum type, and the end cap endoporus is equipped with the guide pin bushing 7 that is mated, and is equipped with oil sealing in guide pin bushing 7 mesopores and the annular groove outside, and bar 8 the inners, resistance position are positioned in guide pin bushing 7 mesopores, and the outer end is equipped with handle or handwheel 9, and a resistance bar cooperates with the end cap center screw for threaded one section.Spool 4 Oil Guide axle journals 10,11,12 are that 1～2 in cone or the Oil Guide axle journal 10,11,12 is cone, and remaining is a cylindrical body.
Claims (1)
- A kind of opening-closing process that is used for hydraulic machinery equipment can be debugged Electro-hydraulic direction valve, remove by solenoid directional control valve 1, damper 2, valve body 3, spool 4, spring 5, outside end cap 6 is formed, it is characterized in that it is that cone or part are cone that this Electro-hydraulic direction valve also has spool stroke controlling device and spool 4 Oil Guide axle journals, the spool stroke controlling device is by guide pin bushing 7, resistance position bar 8 and handle or handwheel 9 are formed, end cap 6 is the wheel drum type, the end cap endoporus is equipped with the guide pin bushing 7 that is mated, be equipped with oil sealing in guide pin bushing 7 mesopores and the annular groove outside, bar 8 the inners, resistance position are positioned in guide pin bushing 7 mesopores, the outer end is equipped with handle or handwheel 9, and resistance position bar cooperates with the end cap center screw for threaded one section.Spool 4 Oil Guide axle journals 10,11,12 are that 1～2 in cone or the Oil Guide axle journal 10,11,12 is cone, and remaining is a cylindrical body.
