Problems solved by technology
In practical applications, there are the following problems: the fluid in the flow path must pass through the inner cavity of the solenoid valve, so some highly corrosive or highly absorptive fluids will cause corrosion problems to the solenoid valve; since each flow path needs to use an independent Solenoid valve, when one of the solenoid valves fails, it is difficult to judge in time; in addition, the entire flow control system is relatively complicated, and the implementation cost is high

The invention discloses a complex flow path state control device and a control method of the complex flow path state control device. The complex flow path state control device comprises a valve body and a valve element. The valve element is connected into the valve body in a sleeved manner. The valve element is provided with first arc-shaped path grooves and second arc-shaped path grooves. First linear path grooves and second linear path grooves are disposed on the valve body. The first curved path grooves and the first linear path grooves are connected with a first ball in an embedded manner.The first linear path grooves and the second linear path grooves communicate with a first transverse through hole and a second transverse through hole formed in the valve body correspondingly. The control method of the complex flow path state control device comprises the following steps that S1, an output shaft of a stepping motor drives the valve element to rotate; S2, fixing plates rotate alongwith the valve element; S4, the contact position of each arc-shaped path groove and the ball changes; S5, the ball moves left and right on the linear path grooves; S6, as the output shaft of the stepping motor rotates by different angles, flow tubes in the first transverse through hole and the second transverse through hole are in different control states.
Description
technical field [0001] The invention relates to the field of fluid control, in particular to a complex flow path state control device and a control method thereof. Background technique [0002] In the field of fluid control, it is often necessary to control and switch the states of multiple flow paths. At present, it is generally realized by using solenoid valves. Specifically, it is necessary to install solenoid valves in each flow path that needs to be controlled, and then open or close each solenoid valve as required, so as to realize the control of the flow path where the solenoid valve is located. state control. In practical applications, there are the following problems: the fluid in the flow path must pass through the inner cavity of the solenoid valve, so some highly corrosive or highly absorptive fluids will cause corrosion problems to the solenoid valve; since each flow path needs to use an independent Solenoid valve, when one of the solenoid valves fails, it is ...
