Description
Technical field
The present invention relates to one kind 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 is raised, and 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 meets requirement by moving from conventional control valve.And when pressure difference is larger, in order to reduce noise and eliminate cavitation erosion
Destruction is general to control valve to solve this problem using porous type sleeve.Current control valve generally only sets a sleeve,
Multiple holes are opened up on sleeve so as to allow fluid flow, the shape of hole, size and number can 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 below attached technical scheme of the invention.
Preferably, the second sleeve upper end is provided with the first flange, and the first sleeve lower end is provided with first and prolongs
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
The second flange is provided with, the second flange and the second extension are spacing mutually.
Preferably, the outer surface of first sleeve is provided with the first projection, and the outer surface of the second sleeve sets
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 stopper protrusion, convex on the outside of stopper protrusion the first sleeve of direction
Go out.
Preferably, the through hole in the second sleeve, 3rd sleeve is circle.
Technique effect of the invention：Many sleeve control valves of the invention realize the obstruct to fluid and tune using three sleeves
Section, consequently facilitating being adjusted according to different fluid control；In addition so that fluid realizes multi-stage jet in sleeve, so as to enter
One step reduction fluid noise.
Brief description of the drawings

Schematic diagram when Fig. 2 is the sleeve rise of the embodiment of the present invention.
Sectional view when Fig. 3 is the sleeve rise of the embodiment of the present invention.
Fig. 4 is the sectional view of the second sleeve of the embodiment of the present invention.
Specific embodiment
Below, substantive distinguishing features of the invention and advantage are further described with reference to example, but the present invention not office
It is limited to listed embodiment.
As shown in Figures 1 to 4, many sleeves control valve 100 of the present embodiment includes 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 slide, and the 3rd sleeve 23 is set in
Second set of 22 outside and relative can slide.The first to 3rd sleeve is coaxially disposed, and is set on described second, third 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 as needed change first to the 3rd
The position of sleeve, so as to change the flow velocity of control valve fluid.When the first to 3rd sleeve is combined, due to the first sleeve
Through hole is not opened up, 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 obstruct of two-layer 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 can be effectively to fluid flow velocity be controlled,
The noise of low control valve can drop 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 the 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 cannot continue motion, so as to prevent the first sleeve from the
Depart from two sleeves.The lower end of the 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 is prevented from
Depart from motion process, it is spacing so as to be carried out to its relative slip.It is raised that the outer surface of first sleeve 21 is 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, described first raised 212 with the clamping of the first groove 224, described second it is raised and
Second groove clamping.By the male-female engagement of above-mentioned technical proposal so that the first sleeve and second sleeve, second sleeve and the 3rd
Relative can be slided between sleeve and prevent from relatively rotating.In the present embodiment, the structure of first, second projection is identical, and first,
The structure of two grooves is identical.The upper end of the 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 protrudes towards second sleeve inner side, 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 protrudes towards the first sleeve outside, spacing so as to be carried out during the decline of the first sleeve.Described second, third sleeve
On through hole 4 for 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 sleeves control valve of the present embodiment realizes the obstruct 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, made an uproar so as to further reduce fluid
Sound.
It is pointed out that above-mentioned preferred embodiment is only explanation technology design of the invention and feature, its object is to
Allow person skilled in the art will appreciate that present disclosure and implement according to this, protection of the invention can not be limited with this
Scope.Any equivalent change or modification in accordance with the spirit of the invention, should all be included within the scope of the present invention.
