Detailed Description
In order to make the purposes, technical solutions and advantages of the implementation of the present application more clear, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the accompanying drawings in the embodiments of the present application.
In order to overcome the problem that the high-pressure explosive gas has noise when being inflated, which is pointed out in the prior art, the application provides a silencing device.
As shown in fig. 1 and 2, the muffler device 10 provided in the present application has a cylindrical body 1, an air flow hole 4 axially provided in the interior of the cylindrical body 1, a radially penetrating muffler hole 2 provided in the substantially middle of the cylindrical body 1, the muffler hole 2 communicating with the air flow hole 4, and a tail outlet 3 provided at the end of the cylindrical body 1, the tail outlet 3 being transited from cylindrical shape to oblate shape.
Preferably, the aperture of the gas flow hole 4 is a through hole which is reduced in size, and the gas filled in the high-pressure gas cylinder flows in through the 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 6mm. 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 into 6mm to 8mm from the diameter which is the same as that of the cylindrical body 1. The diameter of the air flow hole 4 is changed from 4.8mm to 5.8mm to 0.1mm to 0.3mm.
In the muffler device 10 provided by the application, the radius of the muffler hole 2 and the airflow hole in the muffler device are designed according to the characteristics of the gas, so that the disturbance of the gas during inflation can be effectively increased, the flow field becomes more complex, the flow velocity of the gas is reduced, and the noise during inflation is effectively reduced.
The silencer 10 provided by the application is mainly used for filling high-pressure explosive gas, and only one silencing hole 2 is formed in the silencer 10, so that more heat generated by friction when the explosive gas is filled due to the simultaneous occurrence of a plurality of silencing holes can be avoided, the temperature of a gas cylinder is excessively high, an optimal flow field is obtained through calculation, and the noise during filling is greatly reduced.
As shown in fig. 3 and 4, the muffler device 10 may be fixed to a three-way nipple 20 of a high-pressure gas cylinder, which is in communication with an inflation port of the nipple 20, and the nipple 20 may be screwed with the high-pressure gas cylinder to accommodate the muffler device 10 in the high-pressure gas cylinder 30, so that when the high-pressure gas cylinder 30 is inflated, the high-pressure gas flows transversely, and part of the high-pressure gas flows vertically through the nipple 20 to reach the muffler device 10, and is filled into the high-pressure gas cylinder 30 after passing through the muffler device 10.
Compared with the small-flow high-pressure inflammable gas charging process without adopting the muffler device in the prior art, the muffler device provided by the application has the advantages that the noise is greatly reduced during working, so that the noise pollution to the surrounding environment is reduced; after noise is reduced, a worker can accurately read various instructions, and can quickly respond when an emergency is met, so that accident potential is reduced.
The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions easily conceivable by those skilled in the art within the technical scope of the present application should be covered in the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
