It is provided with fourth link 156, fourth link 156 extends second housing 151 and is provided with second handle 157.Second coil 152
After energization, the second armature 153 of driving is moved out, so that the second spool 56 is disengaged with the second connecting hole 14, after power loss, the
Two spools 56 homing under spring force.In addition, in some special circumstances, moreover it is possible to by pulling with hand second-hand
Handle 157 opens the second spool 56.
As shown in Figure 1, when the second electromagnet 150 obtains electric, the first spool 16 resists the 4th when 100 power loss of the first electromagnet
Connecting hole 54, and the second spool 56 is disengaged with the second connecting hole 14, at this point, oil liquid is after the entrance of the 4th connecting hole 54, it can
It pushes the first spool 16 open, and is flowed out by the first, second through flow hole 12,52 from the second connecting hole 14；And if oil liquid is from second
When connecting hole 14 flows into, the first spool 16 is oppressed due to the first spring 19 and resists the 4th connecting hole 54, the pressure of oil liquid can be into one
Step makes the first spool 16 press the 4th connecting hole 54, and therefore, oil liquid will be unable to flow into the 4th connecting hole 54, that is, only allow at this time
Oil liquid is flowed into from the second connecting hole 14, is flowed out from the 4th connecting hole 54.
Correspondingly, as shown in Fig. 2, when the first electromagnet 100 it is electric, when the second 150 power loss of electromagnet, the first spool 16 with
4th connecting hole 54 is detached from, and the second spool 56 and the second connecting hole 14 push against, at this point, oil liquid enters from the second connecting hole 14
Afterwards, the second spool 56 can be pushed open, and flowed out by the first, second through flow hole 12,52 from the 4th connecting hole 54；And if oil liquid from
When 4th connecting hole 54 flows into, the second spool 56 is oppressed due to second spring 59 and resists the second connecting hole 14, the pressure meeting of oil liquid
The second spool 56 is further set to press the second connecting hole 14, therefore, oil liquid will be unable to flow into the second connecting hole 14, that is, at this time only
Allow oil liquid to flow into from the 4th connecting hole 54, is flowed out from the second connecting hole 14.
It will be apparent that when the first, second electromagnet 100,150 it is electric when, the first, second spool 10,50 is in
Opening state, entire valve body is in fully on state at this time；And when the first, second electromagnet 100,150 equal power loss, the
One, the second spool 10,50 is abutted with the 4th connecting hole 54 and the second connecting hole 14 respectively, at this point, entire valve body is in and cuts completely
State only, that is, be disconnected oil circuit.
The electromagnetism check valve in adjustable cutoff direction of the invention by electromagnet driving device change automatically the first spool and
The state of second spool enables this check valve easily to control the direction for preventing oil liquid reverse flow, in addition it can reach
To fully on and cut-off state, function is more diversified, also, simple to operate, high reliablity, is easy to implement automatic
Change.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Those skilled in the art can understand the contents of the present invention and implements accordingly, and protection of the invention can not be limited with this
Range.Any equivalent change or modification in accordance with the spirit of the invention should be covered by the protection scope of the present invention.
