Description
Technical field
The invention belongs to actuator control technology, and in particular to a kind of mode selection valve technology of civil aircraft actuator.
Background technology
Mode selector valve is a kind of mode conversion element, and it belongs to sophisticated product, is mainly used in controlling actuator, by making
Driven with the pilot pressure from the magnetic valve to connect with mode selector valve, mode selector valve is in activation or damping bypass two
One of kind mode, so as to reach the purpose of mode selection.
Traditional mode selector valve, the pressure using only spring and the pilot pressure from magnetic valve are balanced, with up to
To the purpose of mode selection.Under such circumstances, due to only being balanced using only the power of the single aspect of spring from magnetic valve
Larger pilot pressure, just must provide larger spring force using the larger spring of volume weight, and then cause valve
Volume and weight is also bigger, does not reach the purpose for designing light and handy and loss of weight.Simultaneously as spring is present for a long time using can make
The risk that power weakens or disappeared, so just can not balanced solenoid valve pilot pressure so that valve has the risk of failure.
The content of the invention
The purpose of the present invention is：
The present invention proposes a kind of mode selector valve design, by devising a kind of by-pass prot, solves single
Using spring force balanced solenoid valve pilot pressure, the bypass hydraulic coupling effectively brought using by-pass prot, cylinder spring force balances together
Pilot pressure from magnetic valve, so as to share the effect of spring, and reduce the risk of defective valve.
Technical scheme：
A kind of civil aircraft actuator mode selector valve, includes following six part：Inner carrier, spring, outer cover, valve element, promote
Piston, valve pocket；
Outer cover is the cylinder that right-hand member opens wide, and the valve element first paragraph that sits up has infundibulate hollow cavity, and hollow cavity periphery is provided with
Spring pedestal, by being slidably installed in valve element left end hollow cavity, spring is placed in hollow cavity periphery and slided with valve element inner carrier
Dynamic connection, with promoting piston contact to be connected, inner carrier moves valve element in the hollow cavity of valve element；Piston is promoted to withstand the right side of valve element
End face, the move within lumens that both connect in outer cover with valve pocket together；Outer cover is socketed with valve pocket；Valve element is provided with by-pass prot, and
Communicated with infundibulate hollow cavity bottom.
Further, there is the first oil return opening on outer cover, be hollow cavity in outer cover, spring is in the hollow cavity of outer cover.
Further, valve pocket is provided with four and is open, respectively activation mode mouth, bypass mode mouth, oil inlet, second time
Hydraulic fluid port.
The effect of inner carrier is moved in the hollow cavity of valve element, and the hollow cavity of itself and valve element forms a cavity, the cavity
Inside there is the fluid from by-pass prot, the fluid forms bypass pressure to balance the electromagnetic valve guide pressure of a part；Spring
Effect is the electromagnetic valve guide pressure for providing pressure to balance a part of；The effect of outer cover is for installing fixed spring one
End, prevents fluid from overflowing and fixes valve pocket.The effect of valve element is by bypass pressure caused by spring force, by-pass prot and promotes piston
Thrust, moved back and forth in valve pocket, so that activation mode mouth or bypass mode mouth are in an ON state, reached mode selection
Purpose；It is to promote valve core movement for receiving the pilot pressure from magnetic valve to promote piston；The offer of the effect of valve pocket
Cavity, make valve element and promote piston to move back and forth wherein, carry out mode selection.
Beneficial effects of the present invention：
Devise by-pass prot so that the pilot pressure of spring force and the homostasis of oil return hydraulic coupling one from magnetic valve, reach
Reduce spring volume and effectively utilize the purpose of hydraulic coupling, greatly reduce the defective valve risk that spring failure is brought, reached and subtracted
The small volume and weight of valve, improve the safety coefficient of valve.

Fig. 3 mode selector valve activates mode schematic diagram；
Number explanation：1- inner carriers, 2- springs, 3- outer covers, 4- valve elements, 5- promote piston, 6- valve pockets, 7- activation mode
Mouthful, 8- bypass mode mouths, 9- oil inlets, the oil return openings of 10- first, the oil return openings of 11- second, 12- by-pass prots.
Embodiment：
The present invention uses the pilot pressure (PRESS, SOV) from magnetic valve, and the pressure, which is applied to, to be promoted on piston 5, is led to
Cross and promote piston 5 to promote valve element 4 to be moved in the cavity of valve pocket 6, so that the activation mode mouth 7 of valve pocket 6 and bypass mode
Mouth 8 communicates with oil inlet 9 respectively, valve is in one of activation and damping bypass both modalities which so as to reach.
Present invention uses inner carrier 1 and by-pass prot 12, by-pass prot 12 has bypassed the fluid of oil inlet 9, and the fluid flows into
In the cavity that the hollow cavity of inner carrier 1 and valve element 4 is formed, so as to form oil pressure, the pressure of the oil pressure and spring together, balances
The pilot pressure (PRESS SOV) of magnetic valve, hydraulic action is made full use of so as to reach, and mould is can reach using less spring
The purpose of state selection.
When Fig. 2 is that magnetic valve is in bypass mode, the pilot pressure PRESS SOV of magnetic valve scarce capacity is to promote valve
Core 4 moves, and now the fluid from oil inlet 9 flows into bypass mode mouth 8 and by-pass prot 12, the fluid now from by-pass prot 12
Flow into the small cavity in the hollow cavity of inner carrier 1 and valve element 4, so as to produce oil pressure, the oil pressure with spring pressure together, use
To balance PRESS SOV power so that valve is in bypass mode.
When Fig. 3 is that magnetic valve is in activation mode, the pilot pressure PRESS SOV's of magnetic valve pushes movable valve plug motion,
Now the fluid from oil inlet 9 flows into activation mode mouth 7 and by-pass prot 12, now living in the fluid inflow from by-pass prot 12
Plug 1 and valve element 4 hollow cavity in small cavity in, so as to produce oil pressure, the oil pressure with spring pressure together, for balancing
PRESS SOV power so that valve is active.
