Shape is separately positioned in two iron core placing chambers.Electromagnetic coil 2 in two electromagnet respectively around the home at the both ends of outer frame pipe 8,
And ring lives corresponding iron core.When electromagnetic coil 2 is powered, corresponding iron core generates magnetic
Variable spool is arranged in spool sliding cavity 8-1, including bipyramid head rod 6, permanent magnet 7 and pipe sleeve 5.Bipyramid head rod 6
It is made of shaft and conical head.The bottom surface of two conical heads is fixed respectively with two shafts.Permanent magnet 7 is nested at circular ring shape
On shaft.Pipe sleeve 5 is nested on permanent magnet 7.The diameter of pipe sleeve 5 is less than the internal diameter of spool sliding cavity 8-1.The excircle of pipe sleeve 5
On be provided with n convex block 5-1.N convex block 5-1 is uniformly distributed along the circumferential direction of pipe sleeve 5, and contacts with the inner wall of spool sliding cavity 8-1.
The central axis of two conical heads is overlapped with the central axis of two flow-path tubes 4.The basal diameter of conical head is greater than flow-path tube 4
Internal diameter, flow-path tube can be sealed completely.
As shown in figure 4, driving circuit includes DC power supply BT1 and double-point double-throw switch S1.Have in double-point double-throw switch S1
Two contact sets.Contact sets include movable contact (knife i.e. in switch), the first stationary contact and the second stationary contact.Pass through movable contact
Movement, movable contact can be electrically connected with the first stationary contact and the second stationary contact respectively.The synchronous fortune of movable contact in two contact sets
It is dynamic.If a movable contact is electrically connected with corresponding first stationary contact, another movable contact is also electric with corresponding first stationary contact
Connection.Anode, the cathode of DC power supply BT1 is separately connected with the first stationary contact, the second stationary contact in one of contact sets,
And it is separately connected with the second stationary contact, the first stationary contact in another contact sets.Movable contact in one of contact sets with

According to use demand, two flow-path tubes 4 are defined respectively as input pipe, efferent duct.The control of driving circuit is defeated
Enter one I/O mouthfuls of end and controller；Controller output control level signal, so that electromagnet and variable spool on input pipe
On the different generation suction of 7 opposite end magnetic pole of permanent magnet, 7 opposite end of permanent magnet on electromagnet and variable spool on efferent duct
The identical generation repulsion of magnetic pole.
When the fluid in input pipe the pressure of variable spool is greater than magnetic field force that variable spool is subject to (suction being subject to
The sum of repulsion) when, variable spool is entered the fluid in pipe and opens, and the fluid in input pipe is slided by variable spool and spool
Gap between chamber 8-1 side wall flows to efferent duct.Resist the inner end of input pipe due to can be changed spool, thus the fluid in efferent duct without
Method adverse current has the function that stop adverse current into input pipe.
When needing reverse flow, only needs controller to change control level signal, that is, may make the stress side of vario valve core
To variation, at this point, the fluid in efferent duct can flow into input pipe, and the fluid in input pipe can not countercurrently arrive efferent duct.
