Abstract
The invention discloses a gas safety emission silencer. The silencer comprises a silencing pot (1), silencing sheets (2), an inlet pipe (3), a rain hat (4) and an emission port (5), wherein the silencing sheets (2) are arranged inside the silencing pot (1), the inlet pipe (3) and the emission port (5) are arranged at two ends of the silencing pot (1) respectively, the rain hat (4) is installed above the inlet pipe (3), the silencing pot (1) and the silencing sheets (2) are tightly pressed through press rings (6), and the space between the two silencing sheets (2) is filled with gland packing (7). The gas safety emission silencer has the advantages of simple structure, small size, facilitation of manufacturing, low cost, good silencing performance and the like.
Description
Technical field
The present invention is specifically related to a kind of gas safety vent silencer.
Background technique
In prior art, the silencing apparatus of vent systems is by the installation composition of acoustic filtering or sound energy consumption.The expanssion type exhaust silencer adopting on internal-combustion engine at present, sound deadening capacity is little, and its exhaust sound, higher than the noise of other parts, becomes the Main Noise Sources of internal-combustion engine, and air-flow is large by resistance, and power loss is large, and exhaust stroke is long.And the vortex type exhaust silencer recently occurring, although it is differential to reduce preferably exhaust noise, reaches the object of eliminating noise, but its complex structure, manufacturing is difficulty comparatively, and cost is high, air-flow is large by resistance, and power loss is more, therefore is also difficult to promote the use of.
Summary of the invention
Object of the present invention will overcome problems of the prior art exactly, and a kind of simple and reasonable, volume is little, sound deadening capacity is large, power loss is few gas safety vent silencer is provided.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of gas safety vent silencer, comprise silencing pot (1), anechoic sheet (2), inlet duct (3), rainhat (4), outer row mouthful (5), described anechoic sheet (2) is arranged on the inside of silencing pot (1), inlet duct (3) and outer row mouthful (5) are separately positioned on the two ends of silencing pot (1), and rainhat (4) is arranged on the top of inlet duct (3).
Described anechoic sheet (2) has two-layer, and silencing pot (1) is divided into three sections.
Between described anechoic sheet (2) and silencing pot (1), by retainer ring (6), compress.
Between described two-layer anechoic sheet (2), stuffing box packing (7) is housed.
Beneficial effect of the present invention is: safety dumping silencing apparatus of the present invention utilizes anechoic sheet (2) and stuffing box packing (7) to absorb acoustic energy, simple in structure, volume is little, be easy to manufacture, cost is low, acoustic attenuation performance good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, silencing pot; 2, anechoic sheet; 3, inlet duct; 4, rainhat; 5, outer row mouthful; 6, retainer ring; 7, stuffing box packing.
Embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated.
As shown in the figure, a kind of gas safety vent silencer provided by the invention, comprise silencing pot (1), anechoic sheet (2), inlet duct (3), rainhat (4), outer row mouthful (5), anechoic sheet (2) is arranged on the inside of silencing pot (1), inlet duct (3) and outer row mouthful (5) are separately positioned on the two ends of silencing pot (1), and rainhat (4) is arranged on the top of inlet duct (3); Anechoic sheet (2) has two-layer, and silencing pot (1) is divided into three sections; Between anechoic sheet (2) and silencing pot (1), by retainer ring (6), compress; Stuffing box packing (7) is housed between two-layer anechoic sheet (2).
When a kind of gas safety vent silencer of the present invention is used, anechoic sheet (2) and stuffing box packing (7) be the noise of absorbing high-frequency or low frequency well, through experiment, detects, and the maximum sound-damping qualities of silencing apparatus of the present invention reaches 48dB, minimum sound-damping qualities reaches 35dB, has good erasure effect.
Claims (4)
1. a gas safety vent silencer, comprise silencing pot (1), anechoic sheet (2), inlet duct (3), rainhat (4), outer row mouthful (5), it is characterized in that: described anechoic sheet (2) is arranged on the inside of silencing pot (1), inlet duct (3) and outer row mouthful (5) are separately positioned on the two ends of silencing pot (1), and rainhat (4) is arranged on the top of inlet duct (3).
2. a kind of gas safety vent silencer according to claim 1, is characterized in that: described anechoic sheet (2) has two-layer, and silencing pot (1) is divided into three sections.
3. a kind of gas safety vent silencer according to claim 1, is characterized in that: between described anechoic sheet (2) and silencing pot (1), by retainer ring (6), compress.
