Background technique
In the process control of fluid, there is many industrial stokehold valves and carry out throttling for convection cell.Throttling means generation differential pressure, and namely the pressure potential of fluid changes the kinetic energy of fluid into, and throttling element carries out the final element of throttling as control valve convection cell, by the destruction of bearing these kinetic energy discharged and bringing.Due to the demand of operating mode, the differential pressure that throttling produces may be very large, exceeded the ability to bear of throttling element, caused throttling element to lose efficacy.At present, for solving the problem that large differential pressure throttle operating mode produces, the main mode relying on multistage throttle, allows medium pass through tortuous runner thus to discharge kinetic energy step by step, by fluid by speeds control during throttling element at different levels in the scope of safety.
Common multistage throttle part can meet the large differential pressure throttle operating mode of single phase flow medium, but in the cutting condition of multiphase flow medium, accelerate because the high-density medium such as solid phase or liquid phase particle is produced gas phase at a high speed by throttling, also obtain very high speed, very high impact stress is produced by material surface when these high density granulars impact throttling element surface, material surface was lost efficacy, causes throttling element by these high density granular erosion damages.In addition, consider that throttling element must have certain anti-plugging ability, the sectional dimension of single runner can not be too little, and this causes common multistage throttle part to be difficult to increase throttling progression further in limited yardstick, can not reduce the speed of high-density medium further.Therefore common multistage throttle part is not suitable for being applied in the large differential pressure throttle operating mode of multiphase flow medium.
Summary of the invention
For this reason, technical problem to be solved in the utility model is that existing multistage throttle part is for throttling poor performance in multiphase flow medium, provides a kind of throttling element that can meet the large differential pressure regulation operating mode of multiphase flow medium.
For solving the problems of the technologies described above, one of the present utility model can tune up differential pressure throttle part, it comprises, fixed block, and flip sleeve is located at inside described fixed block or the activity adjustment part in outside, some fluid passages are provided with in described fixed block, bending on three Spatial Dimensions of described fluid passage in described fixed block.
Described fixed block forms by several annular slabs are stacked, and it comprises the isolating plate being arranged at two ends, and the some laminar flow guidance tapes between isolating plate, described runner plate offers the breach and runner hole that form described fluid passage.
Runner plate described in every one deck is arranged equably breach described in some groups and described runner hole.
The plate face of described annular slab is vertical with the moving direction of described activity adjustment part.

Technique scheme of the present utility model has the following advantages compared to existing technology:
(1) throttling element fixed block of the present utility model and activity adjustment part composition.Fixed block is provided with some fluid passages, realizes throttling.Because fluid passage is bending on three Spatial Dimensions of fixed block, namely fluid passage has multiple turning, each turning represents a throttling progression, and when fluid will produce significant differential pressure by during a turning, therefore throttling element needs the differential pressure of bearing can be dispersed to turning at different levels; So the throttling progression of these runners is more, the differential pressure that throttling element can bear is also larger.
(2) there is in fixed block of the present utility model the independent flow passage of three dimensional topology.This runner is three enterprising line bend of Spatial Dimension, and because runner can be roundabout in three dimensional space, turning quantity can promote 100% at most relative to the turning quantity of two dimensional topology runner, thus improves throttle efficiency.
(3) fixed block of the present utility model forms by some layers of annular slab is stacked, it comprises and is arranged at the isolating plate at two ends and the runner plate between isolating plate, runner plate has and forms the breach of runner and runner hole, one independently runner need at least four laminatings to be combined.Centre is two-layer is perforated layer, these through hole mutual conduction after being superimposed together, and forms tortuous runner; The structural element that these form runner is evenly distributed on each laminar flow guidance tape, just defines the fixed block with numerous independent flow passage.The separate differential pressure that can ensure that turning at different levels produces on a runner in fluid passage be distributed in fixed block is close, this means that the liquid speed peak value of throttling element inside is lower, makes throttling element throttle efficiency high.
(4) while reducing liquid speed further, in order to promote the ability of material opposing fluid scouring, the material of the utility model throttling element is widia.Widia has very high hardness, makes to have certain toughness simultaneously, is highly suitable for the throttling of multiphase flow medium.Widia part is prepared by the method for powder metallurgy.
