when the patch is wrapped on the valve body, the base layer is tightly attached to the outer wall surface of the valve body;
the flow monitor comprises a content database and an environment acquisition submodule, wherein the content database is provided with p pieces of data corresponding to different contents, each piece of data is provided with n indexes such as the transverse cutting area of liquid in a pipeline where the valve body is positioned, the amount of doped material in the valve body, the flow velocity of the liquid in the valve body and the like, the indexes are digitized, the numerical values of the conditions that whether the valve body needs to be cleaned or not are corresponding to the indexes under different conditions are provided, and the conditions that whether the p pieces of different contents need to be cleaned or not can be represented by a vector Y
Figure 46093DEST_PATH_IMAGE001
Wherein each value in Y is represented by 0,1, 0 represents no need of cleaning, 1 represents need of cleaning, yi represents value of data corresponding to ith data, and then formula (1) is defined
Figure 457482DEST_PATH_IMAGE002
（1）
Wherein in formula (1), xi is the value of the ith index,
Figure 895417DEST_PATH_IMAGE003
is the coefficient of the x,
Figure 909509DEST_PATH_IMAGE004
is the value of the square of the i-th index,
Figure 382079DEST_PATH_IMAGE005
is composed of
Figure 964370DEST_PATH_IMAGE004
I =1,2,3 … … n,
Figure 889601DEST_PATH_IMAGE006
in order to solve for the probability of needing cleaning,
Figure 458117DEST_PATH_IMAGE003
and
Figure 519613DEST_PATH_IMAGE005
it is calculated by the following formula (2):
Figure 272806DEST_PATH_IMAGE007
（2）
wherein
Figure 685333DEST_PATH_IMAGE008
In order to be an intermediate expression,
Figure 306807DEST_PATH_IMAGE009
is the value corresponding to the ith data in the Y vector,
Figure 488389DEST_PATH_IMAGE010
is the expression of substituting the value of the ith piece of data in the database into the formula (1),
Figure 146904DEST_PATH_IMAGE011
is composed of
Figure 46727DEST_PATH_IMAGE012
To pair
Figure 455580DEST_PATH_IMAGE013
Calculating a partial derivative, i =1,2,3, … … j;
then the value in formula (1) can be calculated by formula (2)
Figure 757249DEST_PATH_IMAGE014
And
Figure 586664DEST_PATH_IMAGE015
then solved for
Figure 973783DEST_PATH_IMAGE014
And
Figure 937060DEST_PATH_IMAGE015
the formula (1) is substituted, so that the valve body can be monitored, and at all times, the environment acquisition submodule is used for acquiring the values of the n indexes in the valve body and substituting the values into the solved values
Figure 827656DEST_PATH_IMAGE014
And
Figure 93552DEST_PATH_IMAGE015
the formula (1) of (A) obtains the corresponding
Figure 702388DEST_PATH_IMAGE006
If, if
Figure 220088DEST_PATH_IMAGE006
If the valve body is larger than 1/2, the valve body needs to be cleaned, otherwise, the valve body does not need to be cleaned;
the valve body opening device is characterized by further comprising a user side, the user side is in communication connection with the flow monitor, the flow monitor sends the result of whether the valve body needs to be carried out or not obtained through analysis to the user side, and the user controls the opening mechanism to work according to the result.
