Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
The embodiment of the invention provides a kind of pressure seal parallel slide valves, including valve body 1, valve deck 3, valve 4 and valve rod
2, the junction of the valve deck 3 and valve rod 2 is equipped with packing cavity, and filler 6 is equipped in the packing cavity, is additionally provided on the packing cavity
Filler compacting device 7, the filler compacting device 7 are set on valve rod 2, for compressing filler 6, and the valve 4 includes: first
Flashboard 41, the second flashboard 42, first flashboard 41, the second flashboard 42 form mutually matched concave-convex fit structure, and described
The sealing surface of one flashboard 41, the second flashboard 42 and valve body 1 is sealed using plane contact, and plane contact sealing has sealing effect good
The advantages of, first flashboard 41, the second flashboard 42 being connect with valve rod 2 independently, first flashboard 41, the second flashboard
Inner containment chamber 43 is equipped among 42 interfaces, the inner containment chamber 43 is being equipped with stroke surplus along feed liquor direction；First
Spring 44, first spring 44 are mounted in the inner containment chamber 43,44 both ends of the first spring respectively with the first lock
Plate 41, the second flashboard 42 are fixedly connected；So that first flashboard 41 and the second flashboard 42 can be along 44 active force sides of the first spring
It is slided in the stroke that stroke surplus limits.
The parallel slide valve further include: vacuum cover component 5, the vacuum cover component 5 are set in 2 outside of valve rod,
The vacuum cover component 5 is removably sealingly disposed on the valve deck 3 and forms sealing accommodating chamber with valve deck 3, described to fill out
Material 6, filler compacting device 7 are located in the sealing accommodating chamber, and the vacuum cover component 5 is equipped with leak detection mouth 58；
Leakage detection apparatus, the leakage detection apparatus is connect with the leak detection mouth 58, for detecting the leak case of filler 6.
The working principle of above-mentioned technical proposal are as follows: when valve 4 shuts off, valve rod 2 pushes the first flashboard 41, the second flashboard 42
Into in the runner of valve body 1, since 4 front and back pressure difference of valve is different, along with the flowing of fluid, flashboard is always to valve export side
Offset is bonded the flashboard close to 4 outlet side of valve with 1 sealing surface of valve body by the pressure of fluid, realize runner from close
Envelope, pressure difference is bigger, is bonded closer.
When hunting leak to valve 4, vacuum cover component 5 is sealingly disposed on valve deck 3 and forms sealing with valve deck 3 and is held
Receive chamber, filler 6, filler compacting device 7 are located in the sealing accommodating chamber, leakage detection apparatus and the leak detection mouth 58 on vacuum (-tight) housing connected
It connects, to hunt leak.
Having the beneficial effect that for above-mentioned technical proposal forms concave-convex fit structure the first flashboard 41, the second flashboard by setting
42 and first flashboard 41,42 interface of the second flashboard among be equipped with inner containment chamber 43, inner containment chamber 43 is along feed liquor side
It is equipped with stroke surplus upwards, the first spring 44 is connected in inner containment chamber 43, when above structure valve 4 shuts off, when the first flashboard
41, it is pushed away under the action of Fluid pressure by the effect of the first spring 44 in the second flashboard 42 when the flashboard far from 4 outlet side of valve

Liquid cross-sectional area in pipeline locating for body, valve body is interior to adulterate object amount, the n index such as flow rate of liquid in valve body, and these are referred to
Mark all quantizes, and whether needs the case where carrying out valve body cleaning corresponding to possessing in the case where these indexs be in different situations
Numerical value, whether the p different content is corresponding needs the case where cleaning that can be indicated with vector Y
Y=(y1,y2,y3…yp)
Wherein 0,1 expression of each value in Y, 0 indicates not needing to clean, and 1 indicates occur needing to clean, and yi indicates i-th
The value of data corresponding to data, i=1,2,3 ... p, then defined formula (1)
Wherein in formula (1), xi is i-th of finger target value,For the coefficient of xi,For i-th index square value, βi
ForCoefficient, i=1,2,3 ... n, g (x) are the probability that the needs solved clean,And βiIt needs to utilize following formula
(2) gained is calculated:
Wherein lnL (x) is intermediate expression, yiFor the corresponding value of the i-th data, X in Y-direction amountiIt is the i-th data in database
Value bring the expression formula in formula (1) into,It is right for lnL (x)Ask local derviation, i=1,2,3 ... ... j；
It can then be calculated by formula (2) in formula (1)WithThen it will be solvedWithBand
Enter formula (1), then may be implemented to monitor valve body, at all moment, takes valve intracorporal using environment acquisition submodule
The n finger target value, and carry it into and solvedWithFormula (1) obtain corresponding g (x), if g
(x) it is greater than 1/2 and needs to clean valve body, does not otherwise need cleaning valve body；
It further include user terminal, the user terminal and traffic monitoring module communicate to connect, and the traffic monitoring module is analyzed
The result for carrying out valve body that whether needs out is sent to user terminal, and user controls opening-closing control mechanism work according to it.
