Abstract
This utility model belongs to the current-limiting orifice plate, and particularly relates to a flow-adjustable current-limiting orifice plate. The structure of the flow-adjustable current-limiting orifice plate comprises two rotatable porous orifice plates which abut against with each other. A plurality of orifices are formed on each porous orifice plate, and one of the orifice plates rotates by an angle to block part area of the orifices of the other orifice plate. The flow-adjustable current-limiting orifice plate is simple in structure, which is easy to process and install, and the cost is relatively low.
Description
Technical field
The utility model belongs to restriction orifice, is specifically related to the adjustable restriction orifice of a kind of flow, can be in process system pipeline adjust flux.
Background technique
Orifice plate is as time-honored throttling arrangement, have simple in structure, be easy to installation, reliable performance, cheap, the feature such as maintain easily, in the steam-water pipe systems such as nuclear industry, chemical industry, space flight, be widely used.Restriction orifice utilizes the throttling action of fluid when flowing through orifice plate, limit fluid flow or reduction hydrodynamic pressure.
The restriction orifice adopting is at present standard restriction orifice mostly, and throttle hole area is fixed, unadjustable.This profiled orifice plate is usually inaccurate because early stage, aperture design was calculated, or the change of later stage system, causes orifice plate that manufactory has manufactured cannot meet the requirement of system, can only again process orifice plate, causes the extension of debugging.And for can not determine final flow rate before system debug or having the process system of different flow operating mode, the narrow limitation of this profiled orifice plate is larger.
Chinese patent CN101737509 discloses a kind of orifice plate of capable of regulating flow quantity, by what have the flange of throttle orifice and an orifice plate, cooperatively interacts adjust flux.Although this scheme has also realized the adjusting of flow, need the flange of special processing, for the occasion of mounting flange, cannot use.
Model utility content
The purpose of this utility model is the defect for prior art, provides a kind of flow adjustable restriction orifice, is not only applicable to new construction, be also applicable to reconstruction project, and cost is lower.
The technical solution of the utility model is as follows: the adjustable restriction orifice of a kind of flow, comprise two rotatable multi-hole orifices that fit together, every multi-hole orifice is provided with some throttle orifices, wherein a multi-hole orifice rotates an angle, shelters from a part of throttle hole area of another piece multi-hole orifice.Two multi-hole orifices are arranged between a pair of companion flange and clamp, with bolts between companion flange.
Further, the adjustable restriction orifice of flow as above, wherein, shape, structure, the size of two described multi-hole orifices are identical.
The beneficial effects of the utility model are as follows: restriction orifice provided by the utility model combines by the rotation of two multi-hole orifices, capable of regulating flow quantity, and regulation range is large; The utility model is simple in structure, be convenient to processing and install, and cost is lower.
Accompanying drawing explanation
Fig. 1 is a kind of multi-hole orifice structural representation of the utility model embodiment;
Fig. 2 is two multi-hole orifice Composite Structure of Revolution schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
The utility model is the adjustable restriction orifice of a kind of flow, by the combination of two multi-hole orifices, realizes adjustable throttle hole area, thereby can adjust flux, meets the different traffic requirement of process system.Avoid repeating processing, even can Substitute For Partial modulating valve.
As a specific embodiment, as shown in Figure 1, orifice plate is provided with three throttle orifices 3 to the structure of multi-hole orifice.The hole count of throttle orifice and aperture can be selected as required, thereby can realize different adjusting ratios.
Two multi-hole orifices can adopt same multi-hole orifice, also can adopt different multi-hole orifices.In order to exchange and versatility, the utility model adopts same multi-hole orifice.As shown in Figure 2, shape, structure, the size of multi-hole orifice 1 and multi-hole orifice 2 are identical, by two multi-hole orifices, 1,2 bonded to each other being set together, by inciting somebody to action a wherein angle of multi-hole orifice 2 rotations, shelter from the area of a part of throttle orifice 3 of another piece multi-hole orifice 1, just realized the adjusting of different throttle hole area.The angle of multi-hole orifice 2 rotations is larger, and throttle hole area is less, and flow is also less.
As concrete mode of execution, two multi-hole orifices 1,2 can be arranged between a pair of companion flange and clamp, and between flange and pipeline, adopt welding manner to be connected, with bolts between companion flange.During as need rotation multi-hole orifice, only need unclamp flange bolt and operate.
The utlity model has following advantage: the utility model capable of regulating flow quantity, and regulation range is large; Simple in structure, be convenient to processing and install; Cost is lower.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if of the present utility model these are revised and within modification belongs to the scope of the utility model claim and equivalent technology thereof, the utility model is also intended to comprise these changes and modification interior.
Claims (1)
1. the adjustable restriction orifice of flow, it is characterized in that: comprise two rotatable multi-hole orifices that fit together (1,2), every multi-hole orifice is provided with some throttle orifices (3), wherein a multi-hole orifice (2) rotates an angle, shelter from a part of throttle hole area of another piece multi-hole orifice (1), shape, structure, the size of described two multi-hole orifices (1,2) are identical; Two multi-hole orifices (1,2) are arranged between a pair of companion flange and clamp, with bolts between companion flange.
