Abstract
The invention discloses an exhaust silencer of a compressor and is used for the field of compressors. The exhaust silencer of the compressor comprises a shell in which an air inlet and an air outlet are formed; a silencing cavity is formed between the air inlet and the air outlet of the shell; a choke block for dividing the silencing cavity into a front chamber and a rear chamber is arranged in the shell; orifices which are used for enabling the front chamber and the rear chamber to be communicated and adjustable in aperture are formed in the choke block. According to the exhaust silencer of the compressor, a structural design that the aperture is adjusted is adopted by the orifices in the choke blocks; when the compressor is just started, the aperture of each orifice is increased, the exhaust resistance of the compressor is reduced, and the starting torque of the compressor is reduced. After the compressor is started, the aperture of each orifice in the choke plate is reduced, and the goals that the gas pulsation of exhaust is reduced and the running noise of the compressor is reduced are achieved. According to the exhaust silencer of the compressor disclosed by the invention, through such a design, double effects that a throttling and noise reduction function is kept while the starting torque of the compressor is reduced are achieved.
Description
Technical field
The present invention, for compressor field, particularly relates to a kind of compressor air-discharging baffler.
Background technique
The built-in exhaust throttle plate of traditional compressor muffler, arranges throttle orifice on Rectifier plate, during compressor air-discharging, gas is discharged muffler by suction port, throttle orifice and exhaust port successively.Muffler plays the gas that reduces exhaust by exhaust throttle plate, reduce the object of compressor operating noise.In order to play good throttling action, this throttle orifice diameter need to design very littlely.But very little throttle orifice will produce larger exhaust resistance in compressor start, need compressor that larger starting torque is provided.So be unfavorable for the cost-saving and efficiengy-increasing of the motor of compressor.
Summary of the invention
For addressing the above problem, the invention provides and a kind ofly can reduce compressor start moment, keep the compressor air-discharging baffler of throttling decrease of noise functions simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of compressor air-discharging baffler, comprise the shell that is provided with suction port and relief opening, shell forms silencing cavity between suction port and relief opening, the inside of shell is provided with the Rectifier plate that silencing cavity is divided into forward and backward two Room, and Rectifier plate is provided with forward and backward two Room of conducting and the adjustable throttle orifice in aperture.
Be further used as the improvement of technical solution of the present invention, Rectifier plate comprises the base plate that is provided with through hole and the thermosensitive bimetal that is located at base plate front side, thermosensitive bimetal comprises the variant part of heaving forward and the pressure edge that is located at variant part outer and fits with base plate, and the center of variant part is provided with aperture.
Be further used as the improvement of technical solution of the present invention, thermosensitive bimetal is provided with some expansion joints that extended to edge by aperture.
Be further used as the improvement of technical solution of the present invention, expansion joint is vertical masonry joint or the abnormity seam evenly arranging.
Be further used as the improvement of technical solution of the present invention, shell comprises fore shell and the back cover of mutual fastening, and suction port and relief opening lay respectively on fore shell and back cover, and back cover inner side is provided with the convex edge of placing Rectifier plate, after fore shell and back cover fasten, Rectifier plate is clamped between fore shell and convex edge.
Beneficial effect of the present invention: in this compressor air-discharging baffler, throttle orifice on Rectifier plate adopts the adjustable structural design in aperture, when compressor just starts, increase the aperture of throttle orifice, reduce the exhaust resistance of compressor, reduce the starting torque of compressor; After compressor start, reduce the aperture of throttle orifice on Rectifier plate, and play the gas that reduces exhaust, reduce the object of compressor operating noise.The present invention reduces by so designing to meet the double effects that compressor start moment keeps throttling decrease of noise functions simultaneously.

Embodiment
With reference to Fig. 1～Fig. 7, the invention provides a kind of compressor air-discharging baffler, comprise the shell 1 that is provided with suction port 11 and relief opening 12, shell 1 forms silencing cavity 2 at suction port 11 and 12 of relief openings, the inside of shell 1 is provided with the Rectifier plate 3 that silencing cavity 2 is divided into forward and backward two Room, and Rectifier plate 3 is provided with forward and backward two Room of conducting and the adjustable throttle orifice in aperture.
In this compressor air-discharging baffler, the throttle orifice on Rectifier plate 3 adopts the adjustable structural design in aperture, and the aperture that increases throttle orifice when compressor just starts, reduces the exhaust resistance of compressor, reduces the starting torque of compressor; After compressor start, reduce the aperture of throttle orifice on Rectifier plate 3, and play the gas that reduces exhaust, reduce the object of compressor operating noise.The present invention reduces by so designing to meet the double effects that compressor start moment keeps throttling decrease of noise functions simultaneously.
Concrete, Rectifier plate 3 comprises the base plate 32 that is provided with through hole 31 and the thermosensitive bimetal 33 that is located at base plate 32 front sides, thermosensitive bimetal 33 comprise the variant part 34 of heaving forward and be located at variant part 34 outers and with the pressure of base plate 32 laminatings along 35, the center of variant part 34 is provided with aperture 36.The cross section of shell 1 is rounded, be similarly that circular Rectifier plate 3 is inlayed or and clamping in shell 1 inside.When compressor just starts, the gas temperature that enters silencing cavity 2 from suction port 11 is lower, the thermosensitive bimetal 33 that is located at base plate 32 front sides holds its shape, aperture 36 apertures are maximum, gas passes aperture 36 and through hole 31 from suction port 11 flows into, and discharge from relief opening 12, gas flow process resistance is little, saves the starting torque of compressor.After compressor start, the gas temperature that enters silencing cavity 2 constantly increases, and thermosensitive bimetal 33 is heated rapidly, shape becomes flat by original heaving forward, shrink in aperture 36 apertures, so reach the effect of throttling, thereby play the gas that reduces exhaust, reduce the object of compressor operating noise.
The present invention, in order to reach better the object of distortion, arranges some expansion joints 37 that extended to edge by aperture 36 on thermosensitive bimetal 33, and expansion joint 37 is divided into thermosensitive bimetal 33 structure of Multi-vane type.Certainly, expansion joint 37 can be set to the vertical masonry joint or the abnormity seam that evenly arrange as required.
As the preferred embodiment of the present invention, shell 1 comprises fore shell 13 and the back cover 14 of mutual fastening, suction port 11 and relief opening 12 lay respectively on fore shell 13 and back cover 14, back cover 14 inner sides are provided with the convex edge 15 of placing Rectifier plate 3, after fore shell 13 and back cover 14 fasten, Rectifier plate 3 is clamped between fore shell 13 and convex edge 15.Concrete, the thermosensitive bimetal 33 of Rectifier plate 3 is pressed on base plate 32 along 35 by fore shell 13 by pressing, and base plate 32 compresses laminating with convex edge 15, and final Rectifier plate 3 is limited at shell 1 inside, and silencing cavity 2 is divided into forward and backward two Room.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the modification that these are equal to or replacement are all included in the application's claim limited range.
