Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model that the present invention is protected
Enclose.
Fig. 1 is referred to Fig. 2, a kind of solenoid directional control valve, including valve body 1, the valve element 2 in valve body 1 and oil pocket 3 and
Electromagnet 7 outside valve element, forms sealed control chamber 4, makes control chamber 4 between electromagnet 7, valve element 2 and the three of valve body 1
Do not connect, be connected between control chamber 4 by connecting oil duct 5 with oil pocket 3, connection oil duct 5 makes the fluid between control chamber 4 circulate
Reach balance.Oil pocket 3 is not connected with control chamber 4, will not be delivered in control chamber 4 and be influenceed because of the compression shock of actuator port
Normal commutation.Two control chambers 4 are connected by connecting oil duct 5, valve element 2 is smoothly moved.
In addition, being provided with spring 6 in control chamber 4, the one end of spring 6 is connected on valve element 2, and the other end is connected in control chamber 4.
In addition, being additionally provided with magnetic valve 7 on the other end of control chamber 4.
In addition, being also associated with the governor motion 8 for adjusting spool commutating period on connection oil duct 4, governor motion 8 is installed
On valve body 1, one end is connected with control chamber 4, and the other end is connected with being connected oil duct 5.
In addition, governor motion 8 is the screw with throttling function.The spiral shell with throttling function is added in connection oil duct 5
Minimum area of passage in nail so that when valve element 2 is moved, the connection inner fluid flow process of oil duct 5 reduces, and can thus increase valve
The resistance that core 2 is moved, and then reduce the speed that valve element 2 commutates, reach regulation commutating period, reduce the effect of reversing impact.
In addition, the cross section of connection oil duct 5 is L-type.
In addition, the cross section of connection oil duct 5 is trapezoidal.
Prior art is different from, solenoid directional control valve of the present invention while enabling to valve element still can smoothly commutate, is cut off
Influence of each actuator port compression shock to connection oil duct, enters and produces influence without aligning often commutation, will not produce vibration and make an uproar
Sound.
