Since the leakproofness of sealing surface is to determine the key factor of the life of valve length, prolonged airtightness is not only
The reliability for measuring valve mass even more guarantees that this system is safe and reliable, premise of stable operation.Currently, since valve exists
In use, the pressure flowed through before and after will lead to because of medium is larger, when the flow velocity for flowing through sealing surface is higher, meeting is used for a long time
The phenomenon that causing certain abrasion to valve sealing face, valve is caused to leak, the case where being unable to reach complete sealing.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of valve throttling proposed
Buck configuration is gradually increased by the area that the structure of circulating line can be such that medium passes through, so that reaching reduces medium
The effect of flow velocity impacts sealing surface in order to reduce.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of valve reducing pressure by regulating flow structure, including valve body, the upper end of the valve body are equipped with sealing surface, the valve body it is interior
Wall is fixedly connected with annular slab, and insertion is equipped with the first filter screen on the annular slab, and the inner wall of the valve body slidably connects valve
The side walls of core, the spool are connected on the inner wall of annular slab, and the lower end of the spool is equipped with valve seat, under the valve body
End is equipped with annular groove, is arranged in the valve body there are two the circulating line communicated with the inner top of annular groove, the valve body
Inner wall is set there are two the outlet communicated respectively with two circulating lines, and the inner wall of the annular groove is equipped with filter mechanism.
Preferably, the annular that the annular slab is equipped with the insertion for the first filter screen and matches with the first filter screen
Through-hole.
Preferably, the pipeline aperture of the circulating line becomes larger from lower to upper.
Preferably, two circulating lines, which are symmetrical arranged, forms.
Preferably, the filter mechanism is the second filter screen, and the side wall of second filter screen is fixedly connected on annular groove
Inner wall.
Preferably, the shape of second filter screen is annular.
The utility model has the beneficial effects that
1, by setting circulating line, since the pipeline aperture of circulating line becomes larger from lower to upper, when medium passes through
Area be gradually increased, gradually decrease the flow velocity of its medium will, achieve the effect that reduce medium flow velocity, can be by medium
Influence to sealing surface is preferably minimized；
2, by setting the second filter screen, annular groove, the first filter screen, annular slab, the second filter screen will flow into ring pipe
Media filtration in road, avoids circulating line there is a situation where blocking, the first filter screen can to flow to the medium of sealing surface into
Row filtering avoids the substance in medium from influencing the effect of sealing.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of valve reducing pressure by regulating flow structure structural schematic diagram；
Fig. 2 is the partial enlarged view in the utility model Fig. 1 at A.
In figure: 1 valve body, 2 sealing surfaces, 3 outlets, 4 first filter screens, 5 valve seats, 6 spools, 7 annular slabs, 8 circulating lines, 9
Annular groove, 10 second filter screens.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, the upper end of a kind of valve reducing pressure by regulating flow structure, including valve body 1, valve body 1 is equipped with sealing surface 2, valve
The inner wall of body 1 is fixedly connected with annular slab 7, and insertion is equipped with the first filter screen 4 on annular slab 7, and the inner wall of valve body 1 slidably connects
Spool 6, the side walls of spool 6 are connected on the inner wall of annular slab 7, and the lower end of spool 6 is equipped with valve seat 5, and the lower end of valve body 1 is set
There is the circular groove matched with valve seat 5, the lower end of valve body 1 is equipped with annular groove 9, and there are two interior with annular groove 9 for setting in valve body 1
The circulating line 8 that top communicates, two circulating lines 8 are symmetrical arranged and form, the inner wall of valve body 1 set there are two respectively with two rings
The outlet 3 that shape pipeline 8 communicates, the inner wall of annular groove 9 are equipped with filter mechanism.
Specifically, the annular that annular slab 7 is equipped with the insertion for the first filter screen 4 and matches with the first filter screen 4
Through-hole, the first filter screen 4 can be filtered the medium for flowing to sealing surface 2, and the substance in medium is avoided to influence the effect of sealing
Fruit.
Specifically, the pipeline aperture of circulating line 8 becomes larger from lower to upper, according to hydromechanical principle, works as medium
By area be gradually increased, gradually decrease the flow velocity of its medium will, achieve the effect that reduce medium flow velocity, can will
Influence of the medium to sealing surface 2 is preferably minimized.
Specifically, filter mechanism is the second filter screen 10, and the side wall of the second filter screen 10 is fixedly connected on the interior of annular groove 9
The shape of wall, the second filter screen 10 is annular, and the second filter screen 10 will flow into the media filtration in circulating line 8, avoid annular
There is a situation where block for pipeline 8.
In the utility model, when medium flows through the lower end of valve body 1, medium passes through the junction of valve body 1 lower end and valve seat 5
Between gap get into annular groove 9, medium first passes through the first filter screen 4 and is filtered, avoid filtering circulating line 8 in occur
Then the case where blocking, is flowed into again in two circulating lines 8, since the pipeline aperture of circulating line 8 becomes larger, to make to be situated between
The area of mass flow warp is become larger suddenly by small, thus according to hydromechanical principle, when the area that medium passes through is gradually increased, makes it
The flow velocity of medium will gradually decrease, thus when medium flows out from outlet 3 by circulating line 8, by the drop of circulating line 8
Fast process can gradually increase the area of flow of media in this way, achieve the effect that the flow velocity for reducing medium, can be by medium to close
The influence of cover 2 is preferably minimized, and reduces the abrasion to sealing surface 2.
More than, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, according to the utility model
Technical solution and its utility model design be subject to equivalent substitution or change, should all cover the protection scope of the utility model it
It is interior.
