Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of split type pneumatic control valve, the split type pneumatic adjusting
Valve includes valve body (not shown), pneumatic actuator 10, locator 20 and flexible axle 30, and the pneumatic actuator 10 is arranged at institute
State on valve body, the locator 20 is connected on the pneumatic actuator 10 by flexible axle 30, and the flexible axle 30 will pneumatically be held
The rotational angle of 10 valve position of row mechanism is transferred on locator 20.
The pneumatic actuator 10 is equipped with a valve main shaft contiguous block 11, and the main shaft contiguous block 11 is equipped with a peace
Fill hole.The locator 20 is equipped with a flexible axle fixed frame 21 and a flexible axle contiguous block 22, and the flexible axle fixed frame 21 is by tight
Gu screw is fixedly installed on the locator 20, the flexible axle fixed frame 21 sets the outside of flexible axle contiguous block 22.It is described soft
Axis connection block 22 is equipped with a positioning hole, and the flexible axle fixed frame 21 is equipped with a limit hole, and it is described fixed that the perforation corresponds to
Position hole is set.One end of the flexible axle 30 is installed in the mounting hole on the main shaft contiguous block 11, and the other end of flexible axle 30 is worn
Cross the perforation and be arranged in the location hole.
An erection joint 31 is equipped with the both ends of the flexible axle 30, the erection joint 31 includes an insertion rod 32 and one
Limiting section 33, the outer surface of the insertion rod 32 are equipped with a card slot 35.The limiting section 33 is arranged at the inner side of insertion rod 32,
The lateral surface of the limiting section 33 is equipped with a movable convex block 34.Specifically, it is recessed to be equipped with one for the outer surface of the limiting section 33
Groove, a return spring is equiped with the groove, the activity convex block 34 is arranged at the outside of the return spring, and protrudes from
