Detailed Description
In order to make the implementation objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application.
In order to overcome the problem that high pressure explosive gas has the noise when aerifing that points out in the prior art, this application provides a noise eliminator.
As shown in fig. 1 and 2, the muffler device 10 provided by the present application has a cylindrical body 1, an airflow hole 4 axially provided in the cylindrical body 1, a muffler hole 2 radially penetrating the cylindrical body 1 at a substantially middle position, the muffler hole 2 communicating with the airflow hole 4, a tail outlet 3 provided at a distal end of the cylindrical body 1, the tail outlet 3 transitioning from cylindrical to oblate.
Preferably, the aperture of the gas flow hole 4 is a through hole which is gradually reduced, and the gas filled in the high-pressure gas cylinder flows in from a larger hole.
Further, the cylindrical body 1 of the muffler device 10 has a length of 20mm to 30mm and a diameter of 5mm to 6 mm. The diameter of the silencing hole 2 is about 2.3 mm-2.8 mm; the length of the tail outlet 3 is between 5mm and 6mm, and the width is changed from the diameter same as that of the cylindrical body 1 to 6mm to 8 mm. The diameter of the airflow hole 4 is transited from 4.8 mm-5.8 mm to 0.1 mm-0.3 mm.
In the silencer 10 provided by the application, the radius of the silencing hole 2 and the airflow holes in the silencer are designed according to the characteristics of gas, so that the disturbance of the gas during inflation can be effectively increased, the flow field is more complicated, the flow rate of the gas is reduced, and the noise during inflation is effectively reduced.
The application provides a silencing device 10 mainly used high-pressure explosive gas's packing is used, only is equipped with a noise elimination hole 2 on silencing device 10 to can avoid because a plurality of noise elimination holes appear simultaneously, the friction produces more heats when leading to filling explosive gas, makes the gas cylinder heat up too high, has reachd the optimum flow field through calculating simultaneously, noise when greatly reduced fills.
As shown in fig. 3 and 4, the muffler device 10 may be fixed to a three-way connector 20 of the high-pressure gas cylinder, and communicate with an inflation port of the connector 20, the connector 20 may be connected to the high-pressure gas cylinder by a screw to accommodate the muffler device 10 in the high-pressure gas cylinder 30, when the high-pressure gas cylinder 30 is inflated, the high-pressure gas flows in a lateral direction, and a part of the high-pressure gas flows in a vertical direction through the connector 20 to reach the muffler device 10, and is filled in the high-pressure gas cylinder 30 after passing through the muffler device 10.
Compared with the low-flow high-pressure inflammable gas inflation process without adopting the noise eliminator in the prior art, the noise eliminator greatly reduces the noise during working, thereby reducing the noise pollution to the surrounding environment; after the noise is reduced, workers can accurately and clearly understand various instructions, and can quickly respond when encountering emergency, so that the accident potential is reduced.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application.
