The invention discloses compressor air-discharging baffler, for compressor field, comprise the shell being provided with suction port and relief opening, shell forms silencing cavity between suction port and relief opening, the inside of shell is provided with Rectifier plate silencing cavity being 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.In this compressor air-discharging baffler, the structural design that the throttle orifice on Rectifier plate adopts aperture adjustable, increases the aperture of throttle orifice, reduces the exhaust resistance of compressor, reduce the starting torque of compressor when compressor just starts; After compressor start, reduce the aperture of throttle orifice on Rectifier plate, and play the gas reducing exhaust, reduce the object of compressor operating noise.The present invention is by so designing the double effects meeting and reduce compressor start moment and keep throttling decrease of noise functions simultaneously.
Description
Technical field
The present invention is used 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, Rectifier plate arranges throttle orifice, and during compressor air-discharging, gas discharges muffler by suction port, throttle orifice and exhaust port successively.Muffler plays the gas reducing exhaust by exhaust throttle plate, reduce the object of compressor operating noise.In order to play good throttling action, this orifice diameter needs to design very little.But very little throttle orifice will produce larger exhaust resistance when compressor start, need the starting torque that compressor provides larger.So be unfavorable for the cost-saving and efficiengy-increasing of the motor of compressor.
Summary of the invention
For solving the problem, the invention provides one and 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 being provided with suction port and relief opening, shell forms silencing cavity between suction port and relief opening, the inside of shell is provided with Rectifier plate silencing cavity being 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 being provided with through hole and the thermosensitive bimetal be located on front side of base plate, thermosensitive bimetal comprises the variant part heaved forward and is located at variant part outer and the pressure edge of fitting 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 being extended to edge by aperture.
Be further used as the improvement of technical solution of the present invention, expansion joint is the vertical masonry joint or abnormity seam that evenly arrange.
Be further used as the improvement of technical solution of the present invention, shell comprises the fore shell and back cover that mutually fasten, and suction port and relief opening lay respectively on fore shell and back cover, is provided with the convex edge of placing Rectifier plate inside back cover, 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, the structural design that throttle orifice on Rectifier plate adopts aperture adjustable, increase the aperture of throttle orifice when compressor just starts, 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 reducing exhaust, reduce the object of compressor operating noise.The present invention is by so designing the double effects meeting and reduce compressor start moment and keep 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 being provided with suction port 11 and relief opening 12, shell 1 forms silencing cavity 2 between suction port 11 and relief opening 12, the inside of shell 1 is provided with the Rectifier plate 3 silencing cavity 2 being 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 structural design that the throttle orifice on Rectifier plate 3 adopts aperture adjustable, increases the aperture of throttle orifice, reduces the exhaust resistance of compressor, reduce the starting torque of compressor when compressor just starts; After compressor start, reduce the aperture of throttle orifice on Rectifier plate 3, and play the gas reducing exhaust, reduce the object of compressor operating noise.The present invention is by so designing the double effects meeting and reduce compressor start moment and keep throttling decrease of noise functions simultaneously.
Concrete, Rectifier plate 3 comprises the base plate 32 being provided with through hole 31 and the thermosensitive bimetal 33 be located on front side of base plate 32, thermosensitive bimetal 33 comprise the variant part 34 heaved forward and be located at variant part 34 outer and the pressure of fitting with base plate 32 along 35, the center of variant part 34 is provided with aperture 36.The circular in cross-section of shell 1, be similarly circular Rectifier plate 3 inlayed or and clamping inner at shell 1.When compressor just starts time, the gas temperature entering silencing cavity 2 from suction port 11 is lower, the thermosensitive bimetal 33 be located on front side of base plate 32 holds its shape, aperture 36 aperture is maximum, through aperture 36 and through hole 31 after gas flows into from suction port 11, and discharge from relief opening 12, gas flow resistance is little, saves the starting torque of compressor.After compressor start, the gas temperature entering silencing cavity 2 constantly increases, and thermosensitive bimetal 33 is heated rapidly, shape becomes flat by original heaving forward, aperture 36 aperture is shunk, so reach the effect of throttling, thus play the gas reducing exhaust, reduce the object of compressor operating noise.
The present invention is in order to reach the object of distortion better, and thermosensitive bimetal 33 arranges some expansion joints 37 being extended to edge by aperture 36, and thermosensitive bimetal 33 is divided into the structure of Multi-vane type by expansion joint 37.Certainly, expansion joint 37 can be set to vertical masonry joint or the abnormity seam of evenly setting as required.
As the preferred embodiment of the present invention, shell 1 comprises the fore shell 13 and back cover 14 that mutually fasten, suction port 11 and relief opening 12 lay respectively on fore shell 13 and back cover 14, the convex edge 15 of placing Rectifier plate 3 is provided with inside back cover 14, 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 between base plate 32 by fore shell 13 along 35 by pressure, and base plate 32 and convex edge 15 compress and fit, 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 these equivalent modification or replacement are all included in the application's claim limited range.
