Embodiment shall fall within the protection scope of the present invention.
As shown in Figs. 1-5, a kind of porous transformation flow testing device proposed by the present invention, comprising:
Outer tube 1 and inner tube 2, inner tube 2 is arranged in outer tube 1, and can move along a straight line in outer tube 1；Wherein, outer tube 1
On be relatively set with several first holes 3, the spacing between adjacent first hole 3 differs；Inner tube 2 is provided with several second holes 4, phase
It differs in the distance between adjacent second hole 4；And second hole 4 be oppositely arranged with the first hole 3；
In the present invention, preferred first hole 3 is three；Second hole 4 is three；And the number in the first hole 3 and the second hole 4
Number is decided according to the actual requirements, in the present invention, to be preferably illustrated, it is preferred that three the first holes 3 are respectively exit orifice one
31, exit orifice 2 32 and exit orifice 3 33；Three the second holes 4 are respectively inner hole 1, inner hole 2 42 and inner hole 3 43；
And to carry out the sealing in other holes during use, then in the present invention, it is preferred to, exit orifice 1 and outer
The distance between hole 2 32 is 1.5 times of distance between exit orifice 2 32 and exit orifice 3 33；Between inner hole 1 and inner hole 2 42
Distance is 1.5 times of distance between inner hole 2 42 and inner hole 3 43.
In the present invention, exit orifice 1 can be the flow velocity for being set as 1.5 meters of positions of measurement, and exit orifice 2 32 is 1.2 meters of measurement
The flow velocity of position；Exit orifice 3 33 is the flow velocity for measuring 1.0 meters；Form the first hole 3；And three holes and first in the second hole 4
Three corresponding settings in hole in hole 3, do not repeat further to save space；
Measuring device one end is threaded through in inner tube 2, obtains flow velocity in inner tube 2 by measuring device；In the present invention, preferably
, measuring device is flow tester；When gas or liquid flow through first hole 3 and the second hole 4 on outer tube 1 and inner tube 2
Afterwards, the flow velocity of current state is obtained by measuring device, and according to the position in the first hole 3 of selection and the second hole 4, and then obtain
Flow velocity in the position, and then the measurement of the selection realization flow velocity by different first holes 3 and the second hole 4；
Since the flow velocity of gas and liquid heart position in the duct in the duct is maximum, by changing in pipeline the
Different positions in measurement pipeline are realized so that the first hole 3 and the second hole 4 of connection change in the position in one hole 3 and the second hole 4
The flow velocity set, and first hole 3 and second is got by the flow velocity of the different location relationship directly proportional to duct height
The flow velocity of corresponding position in the case that hole 4 is connected to, and need to replace position again and measure；
As shown in Fig. 2, inner tube 2 is moved in outer tube 1 so that inner hole 2 42 is connected to exit orifice 1, such gas or
Liquid flows out after sequentially passing through exit orifice 1, inner hole 2 42 and the exit orifice 1 of the other side of side, and is flowing through inner tube 2
When, the flow velocity under the state is obtained by measuring device；
As shown in figure 3, inner tube 2 is moved in outer tube 1 so that inner hole 1 is connected to exit orifice 2 32, such gas or

When, the flow velocity under the state is obtained by measuring device；
Such as Fig. 4, inner tube 2 is moved in outer tube 1, so that inner hole 2 42 is connected to exit orifice 3 33, such gas or liquid
It is flowed out after exit orifice 3 33, inner hole 2 42 and the exit orifice 3 33 of the other side of side can be sequentially passed through, and when flowing through inner tube 2, lead to
It crosses measuring device and obtains flow velocity under the state；
By the position of the mobile change inner tube 2 in appearance of inner tube 2, so that a certain first hole 3 and a certain second hole 4
Connection, and other first holes 3 are blocked by inner tube 2, other second holes 4 are blocked by outer tube 1；And then avoid its connection, such gas
Liquid is only capable of the first hole 3 and the second hole 4 of flow communication afterwards, realizes the measurement of different location；
It certainly is the position of preferably limitation inner tube 2, so that content preferably moves in outer tube 1, such as Fig. 5 and Fig. 6 institute
Show, in the present invention, is preferably provided with sliding slot 11 and sliding block 21, which is oppositely arranged on 1 inner wall of outer tube；21 phase of sliding block
To being arranged on the outer wall of inner tube 2, and it is adapted with sliding slot 11；It in this way can be better by the cooperation of sliding slot 11 and sliding block 21
Position of the inner tube 2 in outer tube 1 is limited, and plays the role of slideway during inner tube 2 is mobile；In addition, sliding slot 11 and cunning
The setting position of block 21 will be staggered with the position in the first hole 3 and the second hole 4, avoid influencing being connected to for the first hole 3 and the second hole 4.
In addition, in the present invention, scale is provided on the outer wall of inner tube 2, when being operated, due to several first holes
The distance between 3 and several second holes 4 have been fixed, therefore, by obtaining on the outer surface of inner tube 2 for extending outer tube 1
