Abstract
The invention relates to an adjustment structure with a multi-layer sleeve. The adjustment structure with the multi-layer sleeve comprises a valve body (1). The multi-layer sleeve (4) is mounted on a valve seat (6) in the valve body (1). The adjustment structure with the multi-layer sleeve is characterized in that the multi-layer sleeve (4) is composed of at least two layers of ferrules, a plurality of through holes are formed in each layer of ferrule, and an annular medium passageway is formed between every two adjacent layers of ferrules; at least one annular partition board is fixedly mounted in each medium passageway, so that the medium passageway is divided in the vertical direction. It is proved through the trail that by the adoption of the novel adjustment valve with the partition board type multi-layer sleeve, the problems that when a multi-layer sleeve in the prior art is used under a small-opening-degree working condition, the flow velocity in the sleeve is too high, and consequentially the interior of the sleeve is severely eroded and noise is high can be effectively solved, and thus the service life of the adjustment valve is prolonged.
Description
Technical field
The present invention relates to a kind of multilayer sleeve regulation structure.
Background technique
At present, under operating mode for High Pressure Difference (pressure reduction is greater than 10MPa before and after valve), most of modulating valve adopts Multilayer sleeve structure, find through using, when small guide vane, the flowing space of multilayer sleeve inner is comparatively large, causes the flow velocity of fluid still very fast, erosion for multilayer sleeve is still serious and noise is comparatively large, has a strong impact on the working life of valve.
Summary of the invention
The object of this invention is to provide a kind of multilayer sleeve regulation structure, when effectively can avoid small guide vane, multilayer sleeve is by erosion.
A kind of multilayer sleeve regulation structure, comprise valve body, valve seat in this valve body is provided with multilayer sleeve, its specialization is: described multilayer sleeve is made up of at least 2 layers of lasso, every layer of lasso all has some through holes, and between adjacent two-layer lasso, form the medium runner of a ring-type, at each medium runner internal fixtion, the dividing plate of at least one annular is installed thus this medium runner is separated in vertical direction.
Wherein multilayer sleeve is made up of 2 to 9 layers of lasso, is provided with 1 to 9 dividing plate in the medium runner between each adjacent two-layer lasso.
Wherein each dividing plate is made up of two semicircular ring.
The invention provides a kind of modulating valve of novel diaphragm type multilayer sleeve, through probationary certificate, effectively can to solve in prior art multilayer sleeve under the operating mode of small guide vane, in sleeve, flow velocity is too fast, fluid and problem that noise excessive serious to sleeve inner erosion, thus extend the working life of modulating valve.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is the partial enlarged drawing at A place in Fig. 1;
Accompanying drawing 3 is working principle schematic diagram of the present invention.
Embodiment
As shown in Figure 1, 2, 3, the invention provides a kind of multilayer sleeve regulation structure, comprise valve body 1, valve seat 6 in this valve body 1 is provided with multilayer sleeve 4, described multilayer sleeve 4 is made up of at least two-layer lasso, every layer of lasso all has some through holes, and between adjacent two-layer lasso, forms the medium runner of a ring-type, be installed with the dividing plate of at least one annular vertically at each medium runner thus this medium runner is separated in vertical direction.
Wherein multilayer sleeve 4 is made up of 2 to 9 layers of lasso, in medium runner between each adjacent two-layer lasso, 1 to 9 dividing plate is installed, such as 3 layers of lasso, 2 dividing plates, each dividing plate is made up of two semicircular ring in addition, is welded on lasso on after also can manufacturing separately with lasso is integrally manufactured.
Embodiment 1:
Consult shown in Fig. 1, a kind of multilayer sleeve regulation structure: mainly comprise valve body 1, fluid enters from the left side of valve body 1, and right side goes out.Valve seat 6 is placed on the inner chamber mounting hole of valve body 1, and (diaphragm type) multilayer sleeve 4 is placed on above valve seat 6, and bonnet 2 is placed on valve body 1, also compresses diaphragm type multilayer sleeve 4 simultaneously.It is secondary that the sealing surface of spool 5 and the sealing surface of valve seat 6 form primary seal.
Under operating mode for High Pressure Difference (pressure reduction >=10MPa), multi-stage sleeve is under the operating mode of small guide vane, and the space between sleeve at different levels is comparatively large, and fluid is too fast by flow velocity after sleeve, and direct high speed impact next stage sleeve, easily causes the damage of sleeve.And in order to solve this situation, the technical solution used in the present invention is split in the space in sleeve, under ensureing each aperture, the flow velocity of fluid all can not be excessive, under this thinking is known, the present invention adopts dividing plate that adjacent two-stage sleeve is carried out compartition, ensures that the fluid circulation space under each aperture is consistent.As shown in Figure 2,3, diaphragm type multilayer sleeve 4 of the present invention is respectively one-level sleeve 4.1, one-level dividing plate 4.2, two-level sleeve 4.3, secondary dividing plate 4.4, three grades of sleeves 4.5 from inside to outside, namely have employed 3 layers of lasso, the pattern of 2 dividing plates between every two adjacent lassos.
As shown in Figure 2, split in vertical direction with the space of dividing plate by adjacent two sleeves, form space independently.During concrete use, along with valve rod 3 moves with on movable valve plug 5, fluid enters sleeve, by the dividing plate in sleeve, when different stroke, and the flowing space of control media in sleeve.It is valve opening for different that the present invention mainly deals with problems, and ensure that the flowing space of fluid can be controlled, when avoiding small guide vane, the space of multilayer sleeve 4 is excessive, and flow velocity is too fast, avoids multilayer sleeve 4 by erosion.
The making form of dividing plate should by the restriction of accompanying drawing 2, dividing plate be manufactured with following two kinds of situations, one, dividing plate can with the processing of sleeve one.Two, dividing plate can be independent processing, cuts into two halves, is bumped in sleeve, and in 4 metering orifice place spot welding, prevents dividing plate from rotating; Coordinating between dividing plate cylindrical and the endoporus of next stage sleeve is Spielpassung, ensures that dividing plate can be put into smoothly; There is positioning table between diaphragm type multilayer sleeve 4 and valve seat 6, diaphragm type multilayer sleeve 4 and valve seat 6 can be closely cooperated.
Claims (3)
