Abstract
The utility model overcomes the defects of the prior art, and provides a noise reduction structure of a diaphragm pump, wherein a noise reduction barrier is arranged on a pump pipe, so that the noise is effectively reduced while the transmission flow of the pump is not influenced; in order to solve the technical problem, the utility model discloses a technical scheme be: a noise reduction structure of a diaphragm pump comprises a diaphragm pump body, wherein a partition fence is arranged above a valve plate of the diaphragm pump body and is arranged on the lower side of an upper cover of the diaphragm pump body, the partition fence is of a plate-shaped structure, and a plurality of irregular through holes are formed in the partition fence and are used for reducing noise; the utility model discloses but wide application in diaphragm pump field.
Description
Technical Field
The utility model relates to a structure of making an uproar falls in diaphragm pump belongs to diaphragm pump technical field.
Background
When the existing diaphragm pump works, because the valve plate is continuously flapped, great noise can be generated, and the most of the noise can be transferred along with the pump pipe.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes prior art exists not enough, provides a structure of making an uproar falls of diaphragm pump, sets up the jube of making an uproar that falls on the pump line, when not influencing pump transmission flow, effective noise reduction.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a structure of making an uproar falls in diaphragm pump, includes the diaphragm pump body, the valve block top of the diaphragm pump body is provided with the jube, the jube sets up the upper cover downside at the diaphragm pump body, the jube is platelike structure, just be provided with a plurality of anomalous through-holes on the jube for fall and make an uproar.
The partition is provided with a large round hole at the position right above the valve block, and the inner diameter of the large round hole is larger than the outer diameter of the valve block and used for avoiding damage to the stroke of the valve block.
The partition is arranged above a liquid inlet and outlet pipeline of the diaphragm pump body and is provided with an arc noise reduction block, and the arc noise reduction block and the valve plate are integrally formed.
And the liquid inlet and outlet pipeline of the diaphragm pump body is provided with a bent pipe, and the bent pipe prevents the liquid inlet and outlet pipeline from being directly communicated.
Compared with the prior art, the utility model beneficial effect who has is: the utility model discloses be equipped with the jube at the export of giving vent to anger and admitting air of pump for the valve block slaps the noise and can directly not propagate through giving vent to anger or air inlet. The transmission route of the noise changes along with the change of the air flow transmission direction, and the noise is effectively reduced by the structure while the transmission flow of the pump is not influenced.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
In the figure: 1 is a diaphragm pump body, 2 is a valve plate, 3 is a barrier, 4 is an upper cover, 5 is a through hole, 6 is a large round hole, 7 is a liquid inlet and outlet pipeline, 8 is an arc noise reduction block, and 9 is a bent pipe.
Detailed Description
As shown in fig. 1 and 2, the utility model relates to a structure of making an uproar falls in diaphragm pump, including the diaphragm pump body 1, 2 tops of the valve block of the diaphragm pump body 1 are provided with jube 3, jube 3 sets up the 4 downside at the upper cover of the diaphragm pump body 1, jube 3 is platelike structure, just be provided with an anomalous a plurality of through-holes 5 on the jube 3 for fall and make an uproar.
The partition 3 is provided with a large round hole 6 at a position right above the valve plate 2, and the inner diameter of the large round hole 6 is larger than the outer diameter of the valve plate 2, so that damage to the stroke of the valve plate 2 is avoided.
The partition 3 is arranged above a liquid inlet and outlet pipeline 7 of the diaphragm pump body 1 and is provided with an arc noise reduction block 8, and the arc noise reduction block 8 and the valve plate 2 are integrally formed.
The inlet and outlet liquid pipeline 7 of the diaphragm pump body 1 is provided with an elbow 9, and the elbow 9 prevents the inlet and outlet liquid pipeline 7 from being directly communicated, so that the noise is further reduced.
The utility model discloses be equipped with the jube at the export of giving vent to anger and admitting air of pump for the valve block slaps the noise and can directly not propagate through giving vent to anger or air inlet. The transmission route of the noise changes along with the change of the air flow transmission direction, and the noise is effectively reduced by the structure while the transmission flow of the pump is not influenced.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
