Move the blocking that aforementioned spool realizes the first hydraulic fluid port and the second hydraulic fluid port.Although two-way stop may be implemented in the invention and Electromagnetic Control is led
It is logical, but have the following disadvantages：
(1) maximum pressure in two hydraulic fluid ports is introduced into the oil pocket of main valve plug rear end and lead to the pressure of oil pocket in order to realize
It crosses pilot valve and flows into two hydraulic fluid port mesolow areas, the first unidirectional damping hole, the second unidirectional damping are provided on main valve plug
Hole, third unidirectional damping hole, the 4th damping hole, and it is configured with the runner of corresponding four steel balls, three resilient keys and complexity, add
Work difficulty is big, process costs are high, assembly difficulty is also big.
(2) it is used opened by pilot valve after, the oil of main valve plug rear end oil pocket is leaked by the selection of two steel balls
The lower hydraulic fluid port of pressure in two hydraulic fluid ports, if there are back pressure in the lower hydraulic fluid port of pressure, the unlatching of main valve plug just by
To influence, it will cause that main valve plug pressure drop is excessive, and fever is serious.

In application, the first hydraulic fluid port A and the second hydraulic fluid port B are connected to working connection.
When two-position two-way pilot 12 no power of solenoid valve (that is, second spring 127 pushes up when 122 power loss of coil
Pilot valve 126 is so that the stopper section closes the lower end of the through-hole, pilot valve 126 with this against the stage portion
Above push rod 124 and moved up with moving armature 123), under the active force of the first spring 4, the first hydraulic fluid port A and the is truncated in main valve plug 2
Two hydraulic fluid port B, and the oil liquid of the first hydraulic fluid port A is passed through by the oil liquid of the first damping hole 2a1 into the first control chamber 3a, the second hydraulic fluid port B
It crosses the second damping hole 2c1 and enters the second control chamber 3b, since the outer diameter of the supporting section is equal to the outer diameter of first linkage section,
The pressure of first hydraulic fluid port A acts on the active force downwardly and upwardly generated on main valve plug 2 and balances each other, and the second hydraulic fluid port B pressure is made
Also balanced each other with the active force downwardly and upwardly generated on main valve plug 2, no matter the first hydraulic fluid port A and the second hydraulic fluid port B pressure such as
What changes, and main valve plug 2 is all reliably in off state under the active force of the first spring 4, and the oil liquid of the first hydraulic fluid port A cannot flow
Enter the second hydraulic fluid port B, the oil liquid of the second hydraulic fluid port B can not flow into the first hydraulic fluid port A.
When two-position two-way pilot solenoid valve 12 be powered when (that is, when coil 122 it is electric when, armature 123 moves down, under push rod
124 so that pilot valve 126 overcomes the elastic force of second spring 127 to move down, and the stopper section is made to leave the stage portion downward, with
This lower end to open the through-hole), the first control chamber 3a and the second control chamber 3b are connected to.If being first at this time
Hydraulic fluid port A pressure is greater than the second hydraulic fluid port B pressure, then oil liquid is by the first hydraulic fluid port A through the first damping hole 2a1, the first control chamber 3a, two
The is flowed into simultaneously by third flow channel 2c and the 4th runner 2d after two-way pilot solenoid valve 12, the 5th runner 5b, the second control chamber 3b
Two hydraulic fluid port B, because the effect of the first damping hole 2c1 makes to produce pressure difference between the first hydraulic fluid port A and the first control chamber 3a, due to
The effect of two check valves 11 keeps the pressure of the first control chamber 3a, the second control chamber 3b and the second hydraulic fluid port B of substantially equal, the first hydraulic fluid port
The differential pressure action of A and the first control chamber 3a overcome the active force of the first spring 4 to open up valve port on main valve plug 2, make oil liquid
Second hydraulic fluid port B is flowed by the first hydraulic fluid port A.If being that the second hydraulic fluid port B pressure is greater than the first hydraulic fluid port A pressure at this time, oil liquid is by the
Two hydraulic fluid port B are controlled through the second damping hole 2c1, the second control chamber 3b, the 5th runner 5b, two-position two-way pilot solenoid valve 12, first
The first hydraulic fluid port A is flowed by first runner 2a and second flow channel 2b simultaneously after chamber 3a, because of the second oil of effect of the second damping hole 2c1
Pressure difference is produced between mouth B and the second control chamber 3b, since the effect of the first check valve 10 makes the first control chamber 3a, the second control
The pressure of chamber 3b and the first hydraulic fluid port A are of substantially equal, and the differential pressure action between the second hydraulic fluid port B and the second control chamber 3b is in main valve plug 2
On overcome the active force of the first spring 4 to open up valve port, make oil liquid by the second hydraulic fluid port B flow into the first hydraulic fluid port A.Therefore, pass through
Oil liquid may be implemented by the first hydraulic fluid port A to the second hydraulic fluid port B, the second hydraulic fluid port B to the in the control energization of two-position two-way pilot solenoid valve 12
The bidirectionally conductive of one hydraulic fluid port A.
It, can be with by being pressed downward handle 9 when electric fault or two-position two-way pilot solenoid valve 12 occur and breaking down
It drives drive rod 6 to move upwards and then main valve plug 2 is driven to move upwards opening valve port, lead the first hydraulic fluid port A and the second hydraulic fluid port B
It is logical.
In conclusion the advantages of two-way shut-off valve of electromagnetism-hand-operated double controlled according to an embodiment of the present invention, is：
(1) structure is simple, and main valve plug is easy to process, and overall cost is low.
(2) outer diameter for being equal to first linkage section by the way that the outer diameter of the supporting section is arranged, makes the stress surface of main valve plug 2
Product is balanced, and is influenced main valve plug 2 by the first hydraulic fluid port A, the second hydraulic fluid port B pressure, is reliably fitted in off state.
(3) Handleset directly acts on main valve plug 2, rather than in pilot valve, operating reliability is higher, Bu Huiyin
Manual-operated emergent operation is influenced for electric fault or pilot valve failure.
