Spool 2 can be switched between first position, the second position and the third place.
What needs to be explained here is that first position is that spool 2 be in position as shown in Figure 1, the second position for spool 2 with
First position is mobile for starting point right-to-left, and the third place is that spool 2 is mobile by starting point right-to-left of first position.
More specifically, spool 2 is not by external force (that is, come from when spool 2 is in the first position
The pressure of 5th hydraulic fluid port D, also not by the external force and the 6th hydraulic fluid port C applied from the 6th hydraulic fluid port C pressure or the 5th hydraulic fluid port D
The external force of application is equal, while also not by the active force from Handleset 11, at this point, to bear against first oval for gear needle 71
The right end of the right end in hole 41 and the second slotted hole 22), spool 2 is connected to the first hydraulic fluid port T with the first through-flow slot 201,2 envelope of spool
The second hydraulic fluid port B is closed, spool 2 is connected to third hydraulic fluid port P with the second through-flow slot 202, and spool 2 closes the 4th hydraulic fluid port A and spool 2 is closed
Third is through-flow slot 203.At this point, the first hydraulic fluid port T, the second hydraulic fluid port B, third hydraulic fluid port P and the 4th hydraulic fluid port A are disconnected between any two.
When spool 2 is in the second position, the active force that spool 2 is applied by the 5th hydraulic fluid port D be greater than spool 2 by
The active force that 6th hydraulic fluid port C applies, the active force by Handleset 11, the movement of 2 right-to-left of spool, spool 2 do not make spool 2
First hydraulic fluid port T is connected to the first through-flow slot 201, and spool 2 connects the second hydraulic fluid port B and third hydraulic fluid port P by the second through-flow slot 203
Logical, spool 2 is connected to the 4th hydraulic fluid port A with the through-flow slot 203 of third.At this point, the first hydraulic fluid port T is connected to the 4th hydraulic fluid port A, the second hydraulic fluid port
B is connected to third hydraulic fluid port P.
As shown in Figure 1, due at first position, gear needle 71 respectively with first slotted hole and second slotted hole
Right end be connected, therefore, when being switched to the second position from first position, spool 2 can pass through gear needle 71 drive the first spring base 7
It moves downward, and valve core housing 4 is limited by being fixed seat 5, can not be moved right, and second spring seat 8 is fixed on valve core housing 4
Left end, spool 2 drives the first spring base 7 when moving downward, compresses to spring 10, and the left end of spool 2 is further to the left
The left end of valve core housing 4 is stretched out so as to be spaced a predetermined distance between second connecting rod 114 and second spring seat 8.At the 5th hydraulic fluid port D
When pressure is rebalanced with the pressure at the 6th hydraulic fluid port C, then spool 2 can be under the action of the restoring force of spring 10, from second
It sets and is returned to first position.This will be understood by those skilled in the art.
When spool 2 is in the third place, spool 2 is less than spool 2 by the 6th by the 5th hydraulic fluid port D active force applied
The active force that hydraulic fluid port C applies, the active force by Handleset 11, spool 2 do not move spool 2 from left to right, and spool 2 makes first
Hydraulic fluid port T and the second hydraulic fluid port B is connected to by the first through-flow slot 201, and spool 2 keeps third hydraulic fluid port P and the 4th hydraulic fluid port A through-flow by second
Slot 202 is connected to, and spool 2 closes the through-flow slot 203 of third.At this point, the first hydraulic fluid port T is connected to the second hydraulic fluid port B, third hydraulic fluid port P and
Four hydraulic fluid port A connection.
As shown in Figure 1, due at first position, gear needle 71 respectively with first slotted hole and second slotted hole
Left end be connected, therefore, when being switched to the third place from first position, spool 2 drive valve core housing 4 move from left to right together
Dynamic, the stroke of spool 2 is limited by the first slotted hole 41 and the second slotted hole.It is limited since the first spring base 7 is fixed seat 5
It is fixed, it can not move right, therefore spool 2 will drive fixing piece 9, second spring seat 10 and valve during moving right
Core retainer plate 4 moves right together, and spring 10 is compressed.The pressure at pressure and the 6th hydraulic fluid port C at the 5th hydraulic fluid port D rebalances
When, then spool 2 can be returned to first position from the third place under the action of the restoring force of spring 10.This is for this field skill
For art personnel, it will be understood by.
When spool 2 is in the second position, spool 2 not by the 5th hydraulic fluid port D apply active force and spool 2 not by
The active force applied to the 6th hydraulic fluid port C, spool 2 are moved by the active force of Handleset 11 with band 2 right-to-left of movable valve plug, valve
Core 2 is connected to the first hydraulic fluid port T with the first through-flow slot 201, and spool 2 makes the second hydraulic fluid port B and third hydraulic fluid port P pass through the second through-flow slot
203 connections, spool 2 are connected to the 4th hydraulic fluid port A with the through-flow slot 203 of third.At this point, the first hydraulic fluid port T is connected to the 4th hydraulic fluid port A, the
Two hydraulic fluid port B are connected to third hydraulic fluid port P.
As shown in Figure 1, due at first position, gear needle 71 respectively with first slotted hole and second slotted hole
Right end be connected, therefore, when being switched to the second position from first position, spool 2 can pass through gear needle 71 drive the first spring base 7
It moves downward, and valve core housing 4 is limited by being fixed seat 5, can not be moved right, and second spring seat 8 is fixed on valve core housing 4
Left end, spool 2 drives the first spring base 7 when moving downward, compresses to spring 10, and the left end of spool 2 is further to the left
The left end of valve core housing 4 is stretched out so as to be spaced a predetermined distance between second connecting rod 114 and second spring seat 8.At the 5th hydraulic fluid port D
When pressure is rebalanced with the pressure at the 6th hydraulic fluid port C, then spool 2 can be under the action of the restoring force of spring 10, from second
It sets and is returned to first position.This will be understood by those skilled in the art.
When spool 2 is in the third place, spool 2 is less than spool 2 by the 6th by the 5th hydraulic fluid port D active force applied
The active force that hydraulic fluid port C applies, the active force by Handleset 11, spool 2 do not move spool 2 from left to right, and spool 2 makes first
Hydraulic fluid port T and the second hydraulic fluid port B is connected to by the first through-flow slot 201, and spool 2 keeps third hydraulic fluid port P and the 4th hydraulic fluid port A through-flow by second
Slot 202 is connected to, and spool 2 closes the through-flow slot 203 of third.At this point, the first hydraulic fluid port T is connected to the second hydraulic fluid port B, third hydraulic fluid port P and
Four hydraulic fluid port A connection.
As shown in Figure 1, due at first position, gear needle 71 respectively with first slotted hole and second slotted hole
Left end be connected, therefore, when being switched to the third place from first position, spool 2 drive valve core housing 4 move from left to right together
Dynamic, the stroke of spool 2 is limited by the first slotted hole 41 and the second slotted hole.It is limited since the first spring base 7 is fixed seat 5
It is fixed, it can not move right, therefore spool 2 will drive fixing piece 9, second spring seat 10 and valve during moving right
Core retainer plate 4 moves right together, and spring 10 is compressed.The pressure at pressure and the 6th hydraulic fluid port C at the 5th hydraulic fluid port D rebalances
When, then spool 2 can be returned to first position from the third place under the action of the restoring force of spring 10.This is for this field skill
