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 the part of the embodiment of the present invention, rather than whole embodiments.It is common based on the embodiment in the present invention, this area
All other embodiment that technical staff is obtained under the premise of creative work is not made, belong to the model that the present invention protects
Enclose.
Referring to Fig. 1, a kind of hydraulic control one-way valve, including：Piston rod chamber R3, load chamber R2, upper control chamber R1, lower control
Chamber R4 and valve body 6 processed, valve pocket 9 being provided with the valve body 6, valve element 8 being provided with the valve pocket 9, the upper end of the valve pocket 9 connects
Limit assembly is connected to, the lower end of the valve pocket 9 is connected with piston 10, and the piston 10 is also connected with valve element 8, the lower control
Chamber R4 is arranged at the lower end of piston 10, and motion makes piston rod chamber be connected with R3 load chambers R2 to the valve pocket 9 upwards, retracts original
Position disconnection piston rod chamber R3 connects with load chamber R2's, and motion makes piston rod chamber R3 and upper control to the valve element 8 upwards
Chamber R1 is connected, and retracts and in situ disconnects connecting for piston rod chamber R3 and upper control chamber R1, lower control cavity volume R4 active area
The active area A2 with poppet valve core, the active area A3 of valve pocket are combined and are determined two kinds of different area ratios A4 respectively
In addition, being provided with the first radial hole K2 on the valve pocket 9, the limit assembly is provided with the second radial hole K1, institute
Limit assembly is stated to control the first radial hole K2 and the second radial hole K1 connections or disconnect.
In addition, the limit assembly includes adjusting screw rod 4 and adjustment seat 3, described one end of adjusting screw rod 4 is connected with valve element 8
Connect, the other end is connected in adjustment seat 3, and the second radial hole K1 is opened on adjusting screw rod 4, and the adjusting screw rod 4 controls
First radial hole K2 and the second radial hole K1 connections disconnect.
In addition, the upper end of adjusting screw rod 4 is provided with locking nut 2, the locking nut 2 is located in adjustment seat 3.
In addition, the lower section of the piston 10 connection limited location screw plug 11.
In addition, being connected with (the first back-moving spring 5 on the valve pocket 9, second back-moving spring 7 is connected with the valve element 8.
In addition, the upper end of valve body 6 is additionally provided with protection cap 1, the protection cap 1 is connected to limit assembly upper end.
Hydraulic control one-way valve concrete operating principle of the present invention is as follows：When pressure oil enters from piston rod chamber R3 fashionable, act on
Hydraulic coupling on valve pocket 9 is more than the spring force and load force sum of (the first back-moving spring 5, and valve pocket 9 moves up, piston rod chamber
R3 connects with load chamber R2, and pressure oil enters load chamber R2 from piston rod chamber R3；
When pressure oil enters from load chamber R2, the downward power acted on valve pocket 9, which is more than, makes what valve pocket 9 moved upwards
Power, check valve are closed, and load chamber R2 is not connected with piston rod chamber R3.When the radial directions of the first radial hole K2 and second
When hole K1 is in connected state, hydraulic coupling caused by lower control chamber R4 control pressure is more than the load pressure in upper control chamber R1
When acting on caused hydraulic coupling on valve element 8, valve element 8 moves upwards, and upper control chamber R1 passes through the second radial hole K1 on valve element 8
Connected with piston rod chamber R3, upper control chamber R1 pressure reduces, and acting on power downward on valve pocket 9 and being less than makes valve pocket 9 transport upwards
Dynamic power, valve pocket 9 move upwards, and load chamber R2 connects with piston rod chamber R3, and pressure oil enters piston from load chamber R2
Rod chamber R3.
When the first radial hole K2 and the second radial hole K1 are in blocking state, control pressure of the piston 10 in lower control chamber R1
Moved upwards in the presence of power and push up valve opening core 8, but because the first radial hole K2 and the second radial hole K1 are not connected, upper control
Chamber R1 can not connect with piston rod chamber R3, and the downward power acted on valve pocket 9, which is still more than, makes its power to motion, unidirectionally
Valve continues up still in closed mode, piston 10 in the presence of lower control chamber R4 pressure, piston 10 is withstood on valve pocket
On, when acting on the upward power on valve pocket 9 and being more than downward power, valve pocket 9 is moved upwards, and check valve is opened, pressure oil from
Load chamber R2 enters piston rod chamber R3.
Prior art is different from, hydraulic control one-way valve of the present invention, structure can be simplified, be active in one's movements, stable and reliable in work, system
Cause low.
