Abstract
The utility model relates to a silencer of an air outlet of a pressure shell. The silencer is simple in structure and convenient to produce, can effectively reduce noise, avoids abnormal vibration of a supercharger, and helps the supercharger normally work. The silencer comprises a cylindrical shell, an inner cylinder is installed inside the cylindrical shell, the waist portion of the inner cylinder is provided with an upper protruding circular ring and a lower protruding circular ring, and the two protruding circular rings separate a cavity composed of the inner cylinder and the cylindrical shell into two independent circular-ring cavities. An internal thread is arranged on the upper portion of an inner wall of the cylindrical shell, a chamfer is arranged on the lower portion of the internal thread, a chamfer is arranged inside the bottom end of the inner cylinder, and an external thread is arranged on the outer side of the upper protruding circular ring of the inner cylinder.
Description
Technical field
The utility model relates to the turbosupercharger pressure shell, is specially a kind of pressure shell air outlet baffler.
Background technique
Through the pressurized machine supercharging, the air that blows out in the pressure shell air outlet has very strong pressure and flow velocity, during through long pressure shell runner, can produce and screams and noise, causes the undesired vibrations of pressurized machine, influences the motor proper functioning.
Summary of the invention
To the problems referred to above, the utility model provides a kind of pressure shell air outlet baffler, and it is simple in structure, and is easy to make, can effectively reduce noise, helps the pressurized machine proper functioning.
Its technological scheme is such: a kind of pressure shell air outlet baffler; It is characterized in that: it comprises barrel shrond; Inner cylinder is equipped with in described barrel shrond inside; The waist of described inner cylinder has the annulus of two convexities up and down, and the annulus of described two convexities is separated into two independently toroidal cavities with the cavity of said inner cylinder and said barrel shrond composition.
It is further characterized in that: the top of the inwall of said barrel shrond is provided with internal thread, and the bottom of said internal thread is provided with chamfering; The bottom set inside of described inner cylinder has chamfering, and said inner cylinder leans on the annulus arranged outside of top convexity that outside thread is arranged.
The utility model adopts the baffler of said structure, baffler is contained in place, pressure shell air outlet, when sound wave imports in the baffler; Through two independently behind the cavity; The energy of sound wave will weaken greatly, effectively reduce noise, avoid the undesired vibrations of pressurized machine.
Description of drawings
Fig. 1 is the sectional view of the utility model structure.
Embodiment
Like Fig. 1; The utility model comprises barrel shrond 1; Inner cylinder 2 is equipped with in barrel shrond 1 inside, and the waist of inner cylinder 2 has the annulus 3 and 4 of two convexities up and down, and the cavity that protruding annulus 3 and 4 is formed inner cylinder 2 and barrel shrond 1 is separated into two independently toroidal cavities.The top of the inwall of barrel shrond 1 is provided with internal thread, and the bottom of internal thread is provided with chamfering, and the bottom set inside of inner cylinder 2 has chamfering, and protruding annulus 3 arranged outside have outside thread.
In use; Only need baffler is installed in place, pressure shell air outlet, after sound wave imports in the baffler along with the air of pressure shell air outlet, behind two enclosed cavities; The energy of sound wave will weaken greatly; Just effectively reduce noise, avoided the undesired vibrations of pressurized machine, guaranteed the proper functioning of pressurized machine.
