The poking groove is V-shaped.
The utility model discloses a this kind of structure, the ECU of car passes through the turned position of hall element control pivot, the ECU of car is the corresponding voltage of more navigating mate's control intention output, the voltage passes through the sensor and conducts to make it produce corresponding magnetic field force on the coil winding, and then the turned angle of control magnetic ring and pivot, the rotation of pivot drives the shift fork and rotates and then make the gyro wheel on the connecting rod do displacement from top to bottom along the raceway groove, and then the lift of control valve rod, valve block and valve rod are connected, like this alright control the accurate location and the control of the aperture of valve block and valve port.
The invention is further described with reference to the accompanying drawings and the detailed description.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is a perspective view of a shift fork according to an embodiment of the present invention.
Detailed Description
The present invention will be specifically described below by way of examples.
As shown in fig. 1 and fig. 2, the embodiment discloses a rotary positioning exhaust gas circulation valve, which includes a valve body 1 and a driving part 2, the valve body 1 is provided with a valve port 11 and a valve sheet 3 capable of blocking the valve port 11, the valve sheet 3 is connected to a valve rod 4, the driving part 2 includes a housing 21, a sensor (not shown in the figure) connected to an automobile ECU (ECU is a vehicle control system) is installed in the housing 21, a coil winding 22, a rotating shaft 23 and a magnetic ring 24, the magnetic ring 24 is sleeved on a circumferential wall of the rotating shaft 23, the rotating shaft 23 is rotatably installed at a hollow position of the coil winding 22, the coil winding 22 is electrically connected to the sensor, the coil winding 22 is energized to generate a magnetic force to drive the magnetic ring 24 to rotate, and simultaneously drive the rotating shaft 23 to rotate synchronously, a lower end of the rotating shaft 23 is connected to a rotating disc 5, the rotating disc 5 is provided with symmetrically arranged and, hall element 20 is arranged at the position of the symmetry axis of two magnets 10, the upper end of rotating shaft 23 is connected with a U-shaped shifting fork 6, shifting grooves 61 which are symmetrically arranged are formed in shifting fork 6, valve rod 4 is connected with a radial connecting rod 7, connecting rod 7 penetrates shifting groove 61 and is connected with a roller 8 at the end part, track ring 9 is further arranged on the inner wall of valve body 1, inclined circular arc-shaped track groove 91 is formed in the peripheral wall of track ring 9, and roller 8 is arranged in track groove 91 to move.
The groove 61 is "V" shaped.
