The invention discloses an intermittent adjusting device and a valve control system. The intermittent adjusting device comprises a crankshaft assembly, a compression cylinder assembly, a compensation cylinder assembly, a communicating pipe and a valve control assembly. According to the scheme, the compression ratio of a first compression cylinder to a second compression cylinder is controlled through the crankshaft assembly, so that fluid in the first compression cylinder, the second compression cylinder and the compensation cylinder enters or is discharged out of the compression cylinders through the communicating pipe, a linkage piston drives a connecting rod to do periodic reciprocating motion under abutting of a first reset spring, and then on-off of a switch connected with the linkage piston can be controlled. By adopting the structure, the intermittent adjusting device is good in silence, low in noise, small in friction force, low in manufacturing cost, high in proportion of the maximum starting time in one period and short in time required for on or off a control switch.
Description
technical field [0001] The invention belongs to the technical field of switch control, and in particular relates to an intermittent regulating device and a valve control system. Background technique [0002] Cam mechanism is a common motion mechanism, which is a high-level mechanism composed of three basic components: cam, follower and frame. The cam is a component with a curved profile or a groove, generally a driving part, which performs constant-speed rotary motion or reciprocating linear motion. When the displacement, speed and acceleration of the follower must be changed strictly according to the predetermined law, especially when the original moving part is in continuous motion and the follower must be in intermittent motion, it is most convenient to use the cam mechanism. The motion law of the cam follower depends on the contour line of the cam or the shape of the groove. The cam can convert continuous rotational motion into reciprocating linear motion, and complex m...
