State liquid outlet, the second valve；
（2）Set with the 3rd pipeline of first pipeline connection, one end of the 3rd pipeline located at first valve and
Between the inlet, the 3rd valve is set on the 3rd pipeline, then sets the 4th pipe with second pipeline connection
Road, one end of the 4th pipeline is located between the liquid outlet and second valve, and the is set on the 4th pipeline
Four valves；
（3）First valve and second valve are opened, and closes the 3rd valve and the 4th valve, the liquid
The liquid of body entrance output sequentially passes through first pipeline, the flow controller, second pipeline, and the pressure is passed
The detected value of sensor is contrasted with the aperture of the flow controller；
（4）When the aperture of the flow controller starts more than normal value, and the detected value of the pressure sensor is without substantially change
During change, first valve and second valve are closed, and open the 3rd valve and the 4th valve, by described the
The other end of four pipelines is connected with cleansing medium entrance, and the cleansing medium of cleansing medium entrance output sequentially passes through described the
Two pipelines, the flow controller, first pipeline.
Preferably, the liquid inlet is set to dioxygen water inlet.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：It is of the invention a kind of right
The method of flow controller back washing anti-blocking plug, by setting pressure sensor, the aperture with flow controller is contrasted, and is come
Judge that flow controller, with the presence or absence of situation about blocking, if there is situation about blocking, is then backwashed to flow controller,
Preventing the stopping state of flow controller becomes more serious, enables flow controller normal work.

Specific embodiment
The technical solution of the present invention will be further described below with reference to the accompanying drawings.
It is shown in Figure 1, a kind of above-mentioned method to flow controller back washing anti-blocking plug.
Flow controller 1 is included for being passed through the inlet 2 of dioxygen water liquid, the liquid outlet for pass-out dioxygen water liquid
3, in the present embodiment, heated after the dioxygen water liquid of output is used for and compressed air mixes, to obtain steam state hydrogen peroxide,
The method is comprised the following steps：
（1）The first pipeline 4 that setting is connected with inlet 2, the first pipeline 4 is sequentially communicated liquid inlet 5, the first valve 6, pressure
Sensor 7, inlet 2, then the second pipeline 8 connected with liquid outlet 3 is set, the second pipeline 8 is sequentially communicated liquid outlet 3, second
Valve 9；In the present embodiment, liquid inlet 5 is dioxygen water inlet, and the first valve 6 is used to control whether hydrogen peroxide flows into flow
In controller 1, the second valve 9 is used to control whether hydrogen peroxide flows out from flow controller 1；
（2）The 3rd pipeline 10 that setting is connected with the first pipeline 4, one end of the 3rd pipeline 10 is located at the first valve 6 and inlet 2
Between, the 3rd valve 11 is set on the 3rd pipeline 10, then sets the 4th pipeline 12 connected with the second pipeline 8, the 4th pipeline
12 one end sets the 4th valve 13 between the valve 9 of liquid outlet 3 and second on the 4th pipeline 12；The He of 3rd valve 11
4th valve 13 is respectively used to control the break-make of the 3rd pipeline 10 and the 4th pipeline 12；
（3）5th pipeline 17 is set, and the 5th pipeline 17 is sequentially communicated compressed gas entrance 15, compressed air stream amount controller 16, Wen Qiu
In blender 18；The other end of the second pipeline 8 is also connected on venturi mixer 18, by venturi mixer 18 by second
The liquid hydrogen peroxide of the pass-out of pipeline 8 mixes with the compressed gas of the 5th pass road pass-out；
（4）The first valve 6 and the second valve 9 are opened, and closes the 3rd valve 11 and the 4th valve 13, the output of liquid inlet 5
Hydrogen peroxide is sequentially passed through in flow into after the first pipeline 4, flow controller 1, the second pipeline 8 venturi mixer 18, and pressure is passed
The detected value of sensor 7 is contrasted with the aperture of flow controller 1；
（5）When the aperture of flow controller 1 starts to be more than normal value, and the detected value of pressure sensor 7 without significant change, say
Free flow amount controller 1 begins with blocking, it is necessary to be backwashed；The first valve 6 and the second valve 9 are closed, and opens the 3rd valve
