Description
Technical field
This utility model relates to a kind of iris type multilamellar sleeve adjusting valve.
Background technology
At present, under the operating mode for High Pressure Difference (pressure reduction is more than 10MPa before and after valve), great majority are adjusted
Joint valve uses Multilayer sleeve structure, finds through using, in the case of small guide vane, and multilamellar sleeve
The internal flowing space is relatively big, causes the flow velocity of fluid the most quickly, and the erosion for multilamellar sleeve depends on
So serious and noise is relatively big, have a strong impact on the service life of valve.
Utility model content
The purpose of this utility model is to provide a kind of iris type multilamellar sleeve adjusting valve, it is possible to be prevented effectively from
In the case of small guide vane, multilamellar sleeve is by erosion.
A kind of iris type multilamellar sleeve adjusting valve, including valve body, the valve seat in this valve body is provided with
Multilamellar sleeve, it is particular in that: described multilamellar sleeve is made up of at least 2 layers of lasso, often
All have some through holes on layer lasso, and between adjacent two-layer lasso, form a ring-type medium
Runner, is installed with the dividing plate of at least one annular thus by this medium stream in each medium runner
Road separates in vertical direction.
Wherein multilamellar sleeve is made up of 2 to 9 layers of lasso, Jie between each adjacent two-layer lasso
Mass flow road is provided with 1 to 9 dividing plate.
The most each dividing plate is made up of two semicircular ring.
This utility model provides the regulation valve of a kind of novel iris type multilamellar sleeve, through card on probation
Bright, can effectively solve multilamellar sleeve in prior art and, under the operating mode for small guide vane, flow in sleeve
Speed is too fast, the problem that fluid is serious to sleeve inner erosion and noise is excessive, thus extends regulation valve
Service life.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is the partial enlarged drawing in Fig. 1 at A；
Accompanying drawing 3 is operation principle schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, 2, 3, this utility model provides a kind of iris type multilamellar sleeve adjusting valve,
Including valve body 1, the valve seat 6 in this valve body 1 is provided with multilamellar sleeve 4, described multilamellar set
Cylinder 4 is made up of at least two-layer lasso, all has some through holes on every layer of lasso, and adjacent two
Form a ring-type medium runner between layer lasso, be axially fixed at each medium runner and be provided with
The dividing plate of at least one annular thus this medium runner is separated in vertical direction.
Wherein multilamellar sleeve 4 is made up of 2 to 9 layers of lasso, between each adjacent two-layer lasso
Medium runner is provided with 1 to 9 dividing plate, 2 dividing plates of such as 3 layers lasso, the most each dividing plate
Be made up of two semicircular ring, can integrally manufactured with lasso also can separately fabricated after be welded on lasso.
Embodiment 1:
Refering to shown in Fig. 1, iris type multilamellar sleeve adjusting valve: mainly including valve body 1, fluid is from valve
The left side of body 1 is entered, and right side goes out.Valve seat 6 is placed on the inner chamber installing hole of valve body 1, (iris type)
Multilamellar sleeve 4 is placed on above valve seat 6, and bonnet, 2 is placed on valve body 1, also compress simultaneously every
Board-like multilamellar sleeve 4.It is secondary that the sealing surface of spool 5 and the sealing surface of valve seat 6 constitute primary seal.
Under operating mode for High Pressure Difference (pressure reduction >=10MPa), multi-stage sleeve under the operating mode of small guide vane,
Space between sleeves at different levels is relatively big, and fluid is too fast by flow velocity after sleeve, direct high speed impact next stage
Sleeve, easily causes the damage of sleeve.And in order to solve this situation, the skill that this utility model uses
Art scheme is to be split in the space in sleeve, it is ensured that under each aperture, the flow velocity of fluid all without
Excessive, under this thinking is known, this utility model uses dividing plate that adjacent two-stage sleeve is carried out space
Segmentation, it is ensured that the fluid circulation space under each aperture is consistent.As shown in Figure 2,3, this practicality is new
The iris type multilamellar sleeve 4 of type is respectively one-level sleeve 4.1,4.2, two grades of one-level dividing plate from inside to outside
Sleeve 4.4, three grades of sleeves 4.5 of 4.3, two grades of dividing plates, i.e. have employed 3 layers of lasso, and each two is adjacent
The pattern of 2 dividing plates between lasso.
As shown in Figure 2, with dividing plate, the space of two adjacent sleeves is carried out in vertical direction
Segmentation, forms independent space.Time specifically used, along with the upper shifting of valve rod 3 band movable valve plug 5,
Fluid enters sleeve, by the dividing plate in sleeve, in the case of different strokes, controls medium at set
The flowing space in Tong.It is for different valve openings that this utility model mainly solves problem, it is ensured that
The flowing space of fluid can be controlled, it is to avoid in the case of small guide vane, and the space of multilamellar sleeve 4 is excessive,
Flow velocity is too fast, it is to avoid multilamellar sleeve 4 is by erosion.
The making form of dividing plate should not limited by accompanying drawing 2, and the making of dividing plate has following two situation,
One, dividing plate can be integrally machined with sleeve.Two, dividing plate can be individually processing, cuts into two halves,
It is bumped in sleeve, and spot welding at 4 metering orifices, prevent dividing plate from rotating；Dividing plate cylindrical and next stage set
Cooperation between the endoporus of cylinder is matched in clearance, it is ensured that dividing plate can be put into smoothly；Iris type multilamellar set
There is positioning table between cylinder 4 and valve seat 6, make iris type multilamellar sleeve 4 can closely join with valve seat 6
Close.
