Description
The utility model relates to a kind of modulating valve that can regulate captured area with rotation angle linearly, and it comprises valve body, spool, turning handle etc., is specially adapted to regulate the flow of the heterogeneous fluid in pipeline and the equipment.
The valve that is installed on pipeline and the equipment has gate valve, stop valve, throttle valve, ball valve, stopcock etc., mainly be made for the usefulness of controlling or opening, closing the medium of pipeline and equipment, only when the medium of pipeline and equipment is liquid or gas, just have reliable regulatory function.But related in the material processing procedure is not only simple liquid or simple gas.And the mixture of treatment fluid and solid particle often.Liquid-solid gentle-solid mixing medium in, solid particle to wash away abrasion serious, cause spool and gate quick abrasion, life-span is short, because the flowability of mixture medium is poor, friction factor is big, cause the instability of flow of adjusting, cause flow to diminish so that block because of the solid particle deposition easily.
For can be in the material processing procedure stable regulation control comprise the flow of the fluidised form object of gas-solid and liquid-solid mixture medium, the application number that Kunming Metallurgy Inst proposes provides a kind of wear-out period long for 90200626.6 utility application, and adjusting control is easy, throttling is stable, not susceptible to plugging twin columns core circular hole linearly adjust valve.This modulating valve mainly comprises upper end cap and lower end cap, valve body, two cylindrical spools, two gears, and a handle, fluted on the cylinder around two cylindrical spools, the cylinder groove of two cylindrical spools closes up and constitutes circular throttling passage.As long as in the counterclockwise direction or the clockwise direction turning handle that rotates modulating valve just can reach the purpose of throttling.But this modulating valve still has shortcoming, mainly is that spool is made up of two cylindrical bodys, and an end of each cylinder axis is set with a gear, and two gears are meshing with each other, the structure more complicated, and volume and weight is bigger, and cost is also corresponding higher.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and provides a kind of simple in structure, and convenience is durable, cost is low, use is reliable, widely used easy modulating valve.
The purpose of this utility model can reach by following measure: this modulating valve is formed single-column core semiellipse hole linearly adjust valve by a whole valve body (1) and a cylindrical spool (2) and upper end cap (5).Spool swivel bearing axle (4) is arranged in cylindrical spool (2), turning handle (8) is housed at an end of swivel bearing axle (4).Be embedded with sealing material (6) between swivel bearing axle (4) and the upper end cap (5).Gland nut (7) is housed, at valve body (1) internal surface dress wear resistance lining spare (3) on it.There is a groove (9) at cylinder middle part at cylindrical spool (2) around cylinder, and the cornerite on coupled columns surface is less than 300 °.The section of this groove (9) is a half elliptic, with a madial wall formation half elliptic passage (12) of valve body (1).The basal area of groove (9) increases to maximum value gradually by zero in case of necessity, that is: when cylindrical spool (2) rotates, the area of the half elliptic passage (12) that groove (9) and valve body (1) madial wall constitute can be by the zero area that increases to the outlet (11) that equals modulating valve import (10); During cylindrical spool (2) counterrotating, the area of passage (12) can be reduced to zero by maximum value; The area of passage (12) increases or reduces, and is linear with the angle of cylindrical spool (2) rotation.The big 20mm of overall dimensions of the aspect ratio passage (12) of cylindrical spool (2).The angle of cylindrical spool (2) rotation be the section ab of groove (9) and 0 line with the angle of transverse axis ed, be expressed as 2.Valve body (1) is cast with gray cast iron, plastics or glass fibre reinforced plastic integral, and cylindrical spool (2) is made of rubber, polyurethane, pottery, Cuprum alloy or stainless steel.Sealing material (6) and wear resistance lining spare (3) can adopt rubber, plastics etc.
The drawing of accompanying drawing is described as follows:
Fig. 1 is an erection drawing of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
The utility model is further elaborated below in conjunction with (accompanying drawing) embodiment: according to Fig. 1 and Fig. 2, rotate turning handle (8) with the hand rotation or with power driver in the counterclockwise direction, driven rotary supporting axle (4), drive cylindrical spool (2) along rotational, rotation along with cylindrical spool (2), groove (9) constitutes half elliptic passage (12) with a madial wall of valve body (1), become big gradually by zero, its maximum basal area value equates with the long-pending value of the circle cross section of modulating valve import (10) and outlet (11), rotate turning handle (8) with the hand rotation or by power driver along clockwise direction, driven rotary supporting axle (4), drive cylindrical spool (2) along rotational, passage (12) is by diminishing greatly gradually until closing, therefore, only need in the counterclockwise direction or clockwise direction rotates the turning handle (8) of modulating valve, just can reach with corner and regulate the also purpose of the various fluid flows of controlling plumbing fixtures and equipment linearly.
The operation of modulating valve can be manually, also can be undertaken by actuator (for example power driver etc.).
Single-column core semiellipse hole linearly adjust valve according to Fig. 1 and Fig. 2 manufacturing, it half amasss with the import (10) of the maximum basal area of circular hole and this modulating valve and the circle cross section that exports (11) and to equate, its specification represents that with the import (10) of modulating valve and the diameter of outlet (11) can manufacture nominal diameter is the single-column core semiellipse hole linearly adjust valve of Dg25mm, Dg38mm, Dg50mm, Dg75mm, Dg100mm and bigger specification.
Result's row that the single-column core semiellipse hole linearly adjust valve of nominal diameter Dg50 is measured during for water at medium are as following table:
| Spool corner α | Ο | π／9 | 2π/9 | π/3 | 4π/9 | 5π/9 |
| Flow m 3/S | 0.3937 | 0.3543 | 0.3149 | 0.2756 | 0.2363 | 0.1809 |
| Spool corner α | 2π／3 | 7π／9 | 8π/9 | π | 10π/9 | |
| Flow m 3/s | 0.1575 | 0.1182 | 0.0788 | 0.0394 | 0 |
The utility model has following advantage compared to existing technology:
1, semiellipse hole throttling, stability of flow particularly when throttle rate is high, is difficult for stopping up under low discharge;
2, the increase of semiellipse pore cross section and reduce with spool corner linearly, the convenient adjusting realized control automatically easily;
3, semiellipse hole throttling, wear away little, long service life, can keep fluid flow is certain value;
4, single-column core semiellipse hole linearly adjust valve adaptability is strong, be specially adapted to the slurry of thickness and to have hardness big, the strong solid particle of property shelled by mill and the gas that has granular material--heterogeneous fluids such as solid mixture body are the pipeline and the equipment of medium, can be widely used in industry-by-industries such as metallurgy, chemical industry, coal, oil, building materials, water conservancy, light industry, food.
5, the equipment that can be used as uses, and the easy dismounting of spool is convenient for changing, and material source is extensive, low price etc.;
6, the single-column core semiellipse hole linearly adjust valve major character that provides of the utility model is, a whole valve body and a cylindrical spool are arranged, compare with bicylindrical core circular hole modulating valve, valve body parts reduces, and has saved a cylindrical spool and two gears, designs simplification, make easily, and material province, volume is little, weight saving, cost reduces;
