Concrete, according to actual clinical test data, different running parameters and target flow value corresponding thereto can be organized into data form is stored in clinical data on flows storehouse, or arranged out corresponding data matrix, matched curve etc., and then running parameter and target flow value are embodied in the mode of function expression, such as, if running parameter X=is (X1, X2, X3,), target flow value F, then F=f (X), concrete, can according to the different function expression of actual clinical test and Selection.
Step 103: determine the first controlling value according to described target flow value;
The controlling value that different flow value is corresponding different, and be stored in controller, when determining a certain target flow value, then controller can determine corresponding thereto according to this target flow value the first controlling value.
Step 104: generate the first control signal comprising described first controlling value;
After the first controlling value determined by controller, the first control signal comprising the first controlling value accordingly can be generated, such as, comprise the voltage signal of a certain magnitude of voltage.
Step 105: send described first control signal to described proportioning valve, opens the aperture corresponding with described first controlling value to control described proportioning valve.
When the first control signal acts on proportioning valve, proportioning valve can be opened and the corresponding aperture of the first controlling value, to make the argon flow amount that exports in the pipeline of argon control device corresponding with current operating parameters.
In the present embodiment, argon control device comprises the proportioning valve be connected with air relief valve, in this control method, the current operating parameters that controller can obtain according to the master control set from high-frequency argon pneumoelectric cutter is determined to draw target flow value, and determine the first controlling value according to described target flow value, generate the first control signal comprising described first controlling value, send described first control signal to described proportioning valve, the aperture corresponding with described first controlling value is opened to control described proportioning valve, because proportioning valve is controlled continuously, make it possible to by the aperture of controller control ratio valve to realize the continuous adjustment to argon flow amount, make it possible to export argon gas stream value accurately according to current operating parameters.

Preset Time is provided with in controller, described Preset Time is the time carrying out managing cleaning, can set according to the actual requirements, when reaching Preset Time, controller can obtain the current argon gas stream value that flow transducer gathers again, to judge that whether pipeline cleaning is successful.
Step 316: more described target flow value and the current argon gas stream value again obtained, determines the 4th controlling value according to comparative result;
After controller obtains current argon gas stream value again, current argon gas stream value and target flow value are compared, and determine corresponding 4th controlling value according to pid control algorithm.
Step 317: judge whether described 4th controlling value is greater than described maximum controlling value, when described 4th controlling value is greater than described maximum controlling value, then enters step 320; When described 4th controlling value is less than or equal to described maximum controlling value, enter step 318,
Controller controls, with the size of maximum controlling value, to judge whether the pipeline in this argon control device is cleared up successfully by comparing the 4th.
Step 318: generate the 4th control signal comprising the 4th controlling value;
