Abstract
The utility model relates to a noise eliminating plate type rectifier. A plate type rectifier in the prior art generates vibrations or noises in the using process. Negative influences are brought to a noise eliminating effect as the plate type rectifier is insufficiently sealed in the fixation and installation process. The noise eliminating plate type rectifier is composed of a metal disk (1), wherein the edge of the metal disk is provided with a clamping ring (2), the clamping ring is provided with a group of circular groove wires (3) which are concentric with the disk, the disk is provided with a group of circulation holes (4), a medium inlet end of the circulation hole is provided with a guide section (5), and the guide section is provided with a circular arc section (6). The noise elimination plate type rectifier is applied to natural gas transmission pipelines.
Description
Technical field:
The utility model relates to the board-like rectifier of a kind of eliminated noise.
Background technology:
Existing board-like rectifier in use can produce vibration or noise.In hard-wired process, sealing not, bring adverse effect to soundproof effect.
Summary of the invention:
The purpose of this utility model is to provide the board-like rectifier of a kind of eliminated noise.
Above-mentioned purpose realizes by following technical scheme:
The board-like rectifier of a kind of eliminated noise, its composition comprises: rosette, the edge of described rosette has the ring of clamping, described clamping on ring has one group of annular ditch line concentric with described disk, described disk is provided with one group of opening, the medium inlet end of described opening has diversion section, on described diversion section, has arc section.
The board-like rectifier of described eliminated noise, the arc radius of described arc section is greater than 1/100 of rosette diameter, and the radius of the circular arc on the diversion section at place, described medium inlet should be greater than 1.5mm.
The board-like rectifier of described eliminated noise, the diameter of described opening is identical.
The board-like rectifier of described eliminated noise, the diameter difference of described opening: the through-hole diameter that is positioned at outer shroud is greater than the through-hole diameter that is positioned at ring.
Beneficial effect:
1. the utility model is drilled with a plurality of openings on rosette, and all opening Central Symmetries distribute, and the size dimension of opening has various ways, according to the flow velocity of situ flow body medium, determines.Each opening on rosette is provided with diversion section, and the inner circle of diversion section is arc transition with being connected of disk port.
2. the utility model becomes to clamp ring in the edge designs of rosette, and on ring, with some annular ditch lines, annular ditch line is concentric with rosette, the sealing that by annular ditch line, can make rosette be connected with pad.
3. the common board-like rectifier thickness of the Thickness Ratio of the utility model disk increases, and the thickness of increase must be greater than 1/10, and for example: the thickness of common board-like rectifier is 20mm, and the thickness of the board-like rectifier of eliminated noise of same size should be 22 so.
4. the medium inlet of opening of the present utility model adopts diversion section, arc radius on diversion section is large as far as possible, should be greater than the board-like rectifier of eliminated noise specification 1/100, could produce eliminated noise effect preferably, for example: the board-like rectifier of the eliminated noise that specification is DN150, the radius of the circular arc on the diversion section at place, medium inlet should be greater than 1.5mm; The board-like rectifier of the eliminated noise that specification is DN200, the radius of the circular arc on the diversion section at place, medium inlet should be greater than 2mm.
The accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is left views of accompanying drawing 1.
Accompanying drawing 3 is the partial enlarged drawings of A in accompanying drawing 2.
