Abstract
The utility model relates to a silencer for compressed air exhaust, which comprises a sleeve and is characterized in that the front end of the sleeve is a communicating port, and connected with a compressed air exhaust port; the interior of the sleeve is divided into a plurality of airflow decelerating chambers which are communicated with one another, and each chamber is filled with ventilating and sound attenuation materials; and a plurality of vent holes are arranged at the tail end of the sleeve. With the silence, air discharged at high speed can pass multiple airflow decelerating chambers, and netty ventilating materials in the chambers decreases the speed of the airflow, thus greatly reducing noise generated during discharge of compressed air.
Description
Technical field
The utility model relates to a kind of silencer, particularly a kind of pressurized air exhaust muffling device.
Background technique
Existing compressed air system is discharged into pressurized air in the air when work, and flow velocity is very fast during owing to its discharging, and high speed airflow produces ear-piercing noise, befouling environment.
Summary of the invention
The purpose of this utility model is that a kind of pressurized air exhaust muffling device will be provided, and it allows the air-flow that discharges at a high speed through some grades of air-flow deceleration cavitys, and the flow velocity of pressurized air discharging is reduced, and sound diminishes.
The utility model is achieved in that described a kind of pressurized air exhaust muffling device, and it comprises a sleeve, it is characterized in that: the front end of sleeve is a connecting port, is connected with compressed air outlet port; Be divided into some air-flow deceleration cavitys that are interconnected in the sleeve, be plugged with ventilative quieter material in each cavity; The tail end of sleeve is provided with the plurality of rows pore.
Be provided with three grades or level Four or Pyatyi or six grades of air-flow deceleration cavitys that are interconnected in the sleeve described in the utility model, be provided with more than one intercommunicating pore between each cavity; From the front end of sleeve to the air-flow deceleration cavitys at different levels of the tail end of sleeve, set ventilative quieter material gradually by closely knit to lax; Described ventilative quieter material is the textile material of netted Stainless Steel Wire or sponge or good permeability.
The beneficial effects of the utility model are, the air communication of discharging is at a high speed crossed multistage air-flow deceleration cavity, and the netted gas permeable material in the cavity makes airspeed retarded, reduces the noise of pressurized air discharge process significantly.
Description of drawings
Fig. 1 is the utility model generalized section.
Among the figure: 1. sleeve, 2. connecting port, 3. exhaust port, 4. intercommunicating pore, 5. netted Stainless Steel Wire, 6. sponge, the 7. textile material of good permeability.
Embodiment
A kind of pressurized air exhaust muffling device described in the utility model, as shown in Figure 1, the front end of sleeve 1 is a connecting port 2, is connected with compressed air outlet port; Be divided into three grades of air-flow deceleration cavitys that are interconnected in the sleeve, be plugged with ventilative quieter material in each cavity; The tail end of sleeve is provided with plurality of rows pore 3.Be provided with more than one intercommunicating pore 4 between each cavity; From the front end of sleeve to the air-flow deceleration cavitys at different levels of the tail end of sleeve, set ventilative quieter material gradually by closely knit to lax; Ventilative quieter material in the cavitys at different levels is respectively the textile material 7 of netted Stainless Steel Wire 5, sponge 6, good permeability.The utility model air communication of discharging is at a high speed crossed multistage air-flow deceleration cavity, and the netted gas permeable material in the cavity makes airspeed retarded, reduces the noise of pressurized air discharge process significantly.
