Technical field
The utility model is related to a kind of control valve, more particularly to a kind of many sleeve control valves.
Background technology
At present, in industrial automation fluid control systems, control valve be the fluid control devices be used widely it
One, for the flow or pressure parameter of regulating system.When pressure difference is larger before and after valve, medium is flowed through at control valve throttling, by
In the drastically change of choke area, constriction in flow area, flow velocity rise, pressure declines, and is also easy to produce obstruction stream, flash distillation occurs empty
Change phenomenon, this phenomenon is the main cause for inducing trim destruction and noise.When pressure difference is little before and after valve, medium is just
Permanent current is dynamic can to meet requirement from conventional control valve.And when pressure difference is larger, in order to reduce noise and eliminate cavitation erosion
Destruction, typically solves this problem using porous type sleeve control valve.Current control valve generally only sets a sleeve,
Open up multiple holes on sleeve to allow fluid flow, shape, the size and number of hole can be set according to design requirement, but
It is, once setting, is difficult to change in use.Therefore, existing sleeve control valve is difficult to the need according to different fluid
It is adjusted.

It is attached technical scheme of the present utility model below.
Preferably, the second sleeve upper end is provided with the first flange, and the first sleeve lower end is prolonged provided with first
Extending portion, the first flange and the first extension are spacing mutually, and the second sleeve lower end is provided with the second extension, 3rd sleeve upper end
Provided with the second flange, the second flange and the second extension are spacing mutually.
Preferably, the outer surface of first sleeve is raised provided with first, and the outer surface of the second sleeve is set
There is the second projection, the inner surface of second sleeve is provided with the first groove, and the inner surface of 3rd sleeve is provided with the second groove, described first
Raised and the first groove clamping, described second raised and the second groove clamping.
Preferably, the second sleeve upper end is provided with male part, and male part is protruded towards second sleeve outside, the
One flange protrudes towards second sleeve inner side.
Preferably, the first sleeve upper end is provided with convex on the outside of stopper protrusion, stopper protrusion the first sleeve of direction
Go out.
Preferably, the second sleeve, the through hole in 3rd sleeve are circle.
Technique effect of the present utility model：Many sleeve control valves of the present utility model are realized to fluid using three sleeves
Barrier and regulation, consequently facilitating being adjusted according to different fluid control；In addition so that fluid realizes multistage spray in sleeve
Penetrate, so as to further reduce fluid noise.

Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figures 1 to 4, many sleeve control valves 100 of the present embodiment include valve body 1, sleeve 2 and connecting rod 3, described
Connecting rod 3 is connected with sleeve 2, and sleeve 2 is arranged in valve body 1.The sleeve 2 includes the first sleeve 21, second sleeve 22 and the
Three sleeves 23, the second sleeve 22 is set in the outside of the first sleeve 21 and relative can slided, and the 3rd sleeve 23 is set in
Second set of 22 outside and relative it can slide.First is coaxially disposed to 3rd sleeve, is set on second, third described sleeve 22,23
There is through hole 4, the first sleeve 21 is connected with connecting rod 3.By above-mentioned technical proposal, user can change first to the 3rd as needed
The position of sleeve, so as to change the flow velocity of control valve fluid.When first to 3rd sleeve combines, due to the first sleeve
Through hole is not opened up, and the first sleeve can block fluid；After the first sleeve rises, fluid is by the through hole 4 on second, third sleeve
Sleeve is flowed through, now, due to the barrier of two layers of sleeve, flow velocity is slower；If desired accelerate flow velocity, then rise second sleeve so that
Fluid only need to be that can flow through control valve by 3rd sleeve.Above-mentioned technical proposal effectively can be controlled to the flow velocity of fluid,
The noise of control valve can be reduced simultaneously.Skilled person will appreciate that, the shape of the through hole in second sleeve, 3rd sleeve,
Quantity and big I need to carry out different designs according to design.
As shown in Figures 1 to 4, further, the upper end of second sleeve 22 is provided with the first flange 221, the first set
21 lower ends of cylinder are provided with the first extension 211, and the first flange 221 and the first extension 211 are spacing mutually, i.e., the first sleeve 21 is upward
When moving to the first flange and being in contact with the first extension, the first sleeve can not continue motion, so as to prevent the first sleeve from the
Depart from two sleeves.The lower end of second sleeve 22 is provided with the second extension 222, and the upper end of 3rd sleeve 23 is provided with the second flange
231, the second flange 231 and the second extension 222 are spacing mutually.By above-mentioned technical proposal, first, second sleeve can be prevented
Depart from motion process, so as to be carried out to its relative slip spacing.The outer surface of first sleeve 21 is raised provided with first
212, the outer surface of the second sleeve 22 is provided with the second projection 223, and the inner surface of second sleeve 22 is provided with the first groove 224,
The inner surface of 3rd sleeve is provided with the second groove, first projection 212 and the clamping of the first groove 224, described second it is raised and
Second groove clamping.Pass through the male-female engagement of above-mentioned technical proposal so that the first sleeve and second sleeve, second sleeve and the 3rd
It relative can be slided between sleeve and prevent from relatively rotating.In the present embodiment, first, second raised structure is identical, and first, the
The structure of two grooves is identical.The upper end of second sleeve 22 is provided with male part 225, and male part 225 is towards convex on the outside of second sleeve
Go out, the first flange 221 is towards protrusion on the inside of second sleeve, by setting male part 225 so that second sleeve is dropping to evagination
When portion is with the second Hp contacts, second sleeve stops declining.The upper end of first sleeve 21 is provided with stopper protrusion 213, limit convex
Portion 213 is towards protrusion on the outside of the first sleeve, so as to be carried out during the decline of the first sleeve spacing.Second, third described sleeve
On through hole 4 be circle, through hole is not provided with first sleeve, by setting manhole, so that flow of fluid is more
Smooth, when the first sleeve does not rise, the first sleeve can block the flow of fluid between first passage 5 and second channel 6.
Many sleeve control valves of the present embodiment realize the barrier and regulation to fluid using three sleeves, consequently facilitating according to
Different fluid control is adjusted；In addition so that fluid realizes multi-stage jet in sleeve, so that further reduction fluid is made an uproar
Sound.
It is pointed out that above-mentioned preferred embodiment is only explanation technical concepts and features of the present utility model, its purpose
It is person skilled in the art can understand content of the present utility model and according to this implement, this reality can not be limited with this
With new protection domain.All equivalent change or modifications made according to the utility model Spirit Essence, should all cover in this reality
Within new protection domain.
